    2015-09-01

    Full Text Available The 2014-2020 Common Agricultural Policy (CAP reform defines new rules for farmers including maintenance of the ecological focus area (EFA. Sustainability is also a requirement to meet consumer expectations and a competitive advantage for firms. This paper aims to evaluate the farmers’ intention to implement sustainable practices related to the EFA measure and to the private sustainability schemes proposed by the food industry. The Theory of Planned Behaviour (TPB was applied on a sample of durum wheat producers to analyse intentions 1 to maintain 7% of the arable land as an EFA, and 2 to implement the private sustainability scheme. Structural equation modelling was applied to test for the relative importance of intention determinants. The farmers’ attitude and past behaviour positively affect intentions to implement the EFA, while perceived behavioural control and attitudes predict intentions to adopt the private sustainability scheme. These results suggest possible interventions that public authorities and supply chain leaders might implement to stimulate farmers’ sustainable behaviours.

  8. Do Smallholder, Mixed Crop-Livestock Livelihoods Encourage Sustainable Agricultural Practices? A Meta-Analysis

    Directory of Open Access Journals (Sweden)

    Thomas K. Rudel

    2016-02-01

    Full Text Available As calls for bolstering ecosystem services from croplands have grown more insistent during the past two decades, the search for ways to foster these agriculture-sustaining services has become more urgent. In this context we examine by means of a meta-analysis the argument, proposed by Robert McC. Netting, that small-scale, mixed crop-livestock farming, a common livelihood among poor rural peoples, leads to environmentally sustainable agricultural practices. As predicted, mixed crop-livestock farms exhibit more sustainable practices, but, contrary to predictions, a small scale of operation does not predict sustainability. Many smallholders on mixed crop-livestock farms use sustainable practices, but other smallholders practice a degrading, input-scarce agriculture. Some large farm operators use soil-conserving, minimum-tillage techniques while other large operators ignore soil-conserving techniques and practice an industrialized, high chemical input agriculture. The strength and pervasiveness of the link in the data between mixed crop-livestock farming and sustainable agricultural practices argues for agricultural policies that promote mixed crop-livestock livelihoods.

  9. Sustainable Agricultural Marketing Initiatives

    Full Text Available Sustainable marketing is a holistic approach that puts equal emphasis on environmental, social equity, and economic concerns in the development of marketing strategies. The purpose of the study is to examine and discuss the sustainable agricultural marketing initiatives practiced throughout the World and Turkey, and to put forth suggestions to further improve the performance of agricultural marketing initiatives in Turkey. Some of the sustainable agricultural marketing initiatives practiced around the world are carried out through civil organizations. Furthermore; some of these initiatives have also launched by farmers, consumers, food processors and retailers. The long-term strategies to increase these initiatives should be determined due to the fact that examples of successful sustainable agricultural marketing initiatives are inadequate and cannot be spread in Turkey. In this context, first of all, the supports provided by the government to improve agricultural marketing systems, such as EU funds for rural development should be compatible with the goals of sustainable marketing. For this purpose, it should be examined whether all proposed projects related to agricultural marketing meet the social, economic, and environmental principles of sustainable marketing. It is important that supporting organizations, especially civil society organisations, should take an active role for faster dissemination and adoption of sustainable agricultural marketing practices in Turkey. These organizations may provide technical assistance in preparing successful project proposals and training to farm groups. In addition, the other organizations, such as local administrations, producers' associations, cooperatives, can contribute to the success of sustainable agricultural marketing initiatives. The use of direct marketing strategies and vertical integration attempts in sustainable agricultural marketing initiatives that will likely be implemented in Turkey is

  10. Innovation, Cooperation, and the Perceived Benefits and Costs of Sustainable Agriculture Practices

    Directory of Open Access Journals (Sweden)

    Mark Lubell

    2011-12-01

    Full Text Available A central goal of most sustainable agriculture programs is to encourage growers to adopt practices that jointly provide economic, environmental, and social benefits. Using surveys of outreach professionals and wine grape growers, we quantify the perceived costs and benefits of sustainable viticulture practices recommended by sustainability outreach and certification programs. We argue that the mix of environmental benefits, economic benefits, and economic costs determine whether or not a particular practice involves decisions about innovation or cooperation. Decision making is also affected by the overall level of knowledge regarding different practices, and we show that knowledge gaps are an increasing function of cost and a decreasing function of benefits. How different practices are related to innovation and cooperation has important implications for the design of sustainability outreach programs. Cooperation, innovation, and knowledge gaps are issues that are likely to be relevant for the resilience and sustainability of many different types of social-ecological systems.

    Full Text Available In the framework of the 16th National Meeting of the Italian Ecological Society (“Global Change, Ecological Diversity and Sustainability”, University of Tuscia, Viterbo, 19-22 September 2006, a symposium was devoted to “Agroecology and Sustainable Development”. A major goal of this symposium was to contribute to keeping the dialogue among the experts of the various disciplines alive. Sustainability of agriculture is a challenge for society world wide. Universities and society as a whole have a responsibility in re-examining current perception of nature, of the world and of human society in the light of natural resources depletion, increasing pollution and social inequalities. The urgency to address sustainability issues is increasingly being reflected in the manner in which institutions of higher education around the world are giving priority to the teaching, research and practice of sustainability. The University of Tuscia is involved in international initiatives concerning teaching and research in Agroecology and Sustainable Agriculture.

    In order to support agribusiness and to attain food security for ever-increasing populations, most countries in the world have embraced modern agricultural technologies. Ecological consequences of the technocentric approaches, and their sustainability and impacts on human health have, however, not received adequate attention particularly in developing countries. India is one country that has undergone a rapid transformation in the field of agriculture by adopting strategies of the Green Revolution. This article provides a comparative analysis of the effects of older and newer paradigms of agricultural practices on ecosystem and human health within the larger context of sustainability. The study was conducted in three closely situated areas where different agricultural practices were followed: (a) the head-end of a modern canal-irrigated area, (b) an adjacent dryland, and (c) an area (the ancient area) that has been provided with irrigation for some 800 years. Data were collected by in-depth interviews of individual farmers, focus-group discussions, participatory observations, and from secondary sources. The dryland, receiving limited rainfall, continues to practice diverse cropping centered to a large extent on traditional coarse cereals and uses only small amounts of chemical inputs. On the other hand, modern agriculture in the head-end emphasizes continuous cropping of rice supported by extensive and indiscriminate use of agrochemicals. Market forces have, to a significant degree, influenced the ancient area to abandon much of its early practices of organic farming and to take up aspects of modern agricultural practice. Rice cultivation in the irrigated parts has changed the local landscape and vegetation and has augmented the mosquito population, which is a potential vector for malaria, Japanese encephalitis and other diseases. Nevertheless, despite these problems, perceptions of adverse environmental effects are lowest in the heavily irrigated area.

    Sustainable water management typically emphasizes water resource quantity, with focus directed at availability and use practices. When attention is placed on sustainable water quality management, the holistic, cross-sector perspective inherent to sustainability is often lost. Proper water quality management is a critical component of sustainable development practices. However, sustainable development definitions and metrics related to water quality resilience and management are often not well defined; water quality is often buried in large indicator sets used for analysis, and the policy regulating management practices create sector specific burdens for ensuring adequate water quality. In this research, we investigated the methods by which water quality is evaluated through internationally applied indicators and incorporated into the larger idea of "sustainability." We also dissect policy's role in the distribution of responsibility with regard to water quality management in the United States through evaluation of three broad sectors: urban, agriculture, and environmental water quality. Our research concludes that despite a growing intention to use a single system approach for urban, agricultural, and environmental water quality management, one does not yet exist and is even hindered by our current policies and regulations. As policy continues to lead in determining water quality and defining contamination limits, new regulation must reconcile the disparity in requirements for the contaminators and those performing end-of-pipe treatment. Just as the sustainable development indicators we researched tried to integrate environmental, economic, and social aspects without skewing focus to one of these three categories, policy cannot continue to regulate a single sector of society without considering impacts to the entire watershed and/or region. Unequal distribution of the water pollution burden creates disjointed economic growth, infrastructure development, and policy

  16. Cyanobacterial Farming for Environment Friendly Sustainable Agriculture Practices: Innovations and Perspectives

    2018-02-01

    Full Text Available Sustainable supply of food and energy without posing any threat to environment is the current demand of our society in view of continuous increase in global human population and depletion of natural resources of energy. Cyanobacteria have recently emerged as potential candidates who can fulfill abovementioned needs due to their ability to efficiently harvest solar energy and convert it into biomass by simple utilization of CO2, water and nutrients. During conversion of radiant energy into chemical energy, these biological systems produce oxygen as a by-product. Cyanobacterial biomass can be used for the production of food, energy, biofertilizers, secondary metabolites of nutritional, cosmetics, and medicinal importance. Therefore, cyanobacterial farming is proposed as environment friendly sustainable agricultural practice which can produce biomass of very high value. Additionally, cyanobacterial farming helps in decreasing the level of greenhouse gas, i.e., CO2, and it can be also used for removing various contaminants from wastewater and soil. However, utilization of cyanobacteria for resolving the abovementioned problems is subjected to economic viability. In this review, we provide details on different aspects of cyanobacterial system that can help in developing sustainable agricultural practices. We also describe different large-scale cultivation systems for cyanobacterial farming and discuss their merits and demerits in terms of economic profitability.

    The extensive use of fertilizers has become one of the most challenging environmental issues in agricultural catchment areas. In order to reduce the negative impacts from agricultural activities and to accomplish the objectives of the European Water Framework Directive we must consider the implementation of sustainable agricultural practices. In this study, we assess sustainable agricultural practices based on reductions in N-fertilizer application rates (from 100% to 0%) and N-application methods (single, split and slow-release) across key agricultural land use classes in the Vouga catchment, Portugal. The SWAT model was used to relate sustainable agricultural practices, agricultural yields and N-NO3 water pollution deliveries. Results show that crop yields as well as N-NO3 exportation rates decrease with reductions in N-application rates and single N-application methods lead to lower crop yields and higher N-NO3 exportation rates as compared to split and slow-release N-application methods.

  1. Smallholder Farmers’ Perceptions on Climate Change and the Use of Sustainable Agricultural Practices in the Chinyanja Triangle, Southern Africa

    2017-03-01

    Full Text Available In developing regions with high levels of poverty and a dependence on climate sensitive agriculture, studies focusing on climate change adaptation, planning, and policy processes, have gained relative importance over the years. This study assesses the impact of farmer perceptions regarding climate change on the use of sustainable agricultural practices as an adaptation strategy in the Chinyanja Triangle, Southern Africa. In this empirical approach, we adopt methods that account for the plausibility that unmeasured characteristics exist, which are correlated with perceptions and the adoption of Sustainable Agricultural Practices. We use a unique and representative dataset collected in December 2012 and June 2013, from smallholder farmers in the Chinyanja Triangle. The results indicate that farmer’s perceptions significantly influence the use of sustainable agricultural practices. Specifically, we established that farmer perceptions considerably impact the use of grain legume rotations, inorganic fertilizers, compost, and farmyard manure. Our results highlight the need for a serious and perhaps equal consideration of farmer perceptions regarding climate change, as important inputs to climate change adaptation policies targeted at enhancing climatic resilience in smallholder farming communities. This is plausible as the adaptation and pliability of farmers to the effects of climate change should be a social process involving the collective efforts from various stakeholders.

    2016-07-01

    Excessive use of chemical fertilizers to increase production from available land has resulted in deterioration of soil quality. To prevent further soil deterioration, the use of methylotrophic bacteria that have the ability to colonize different habitats, including soil, sediment, water, and both epiphytes and endophytes as host plants, has been suggested for sustainable agriculture. Methylotrophic bacteria are known to play a significant role in the biogeochemical cycle in soil ecosystems, ultimately fortifying plants and sustaining agriculture. Methylotrophs also improve air quality by using volatile organic compounds such as dichloromethane, formaldehyde, methanol, and formic acid. Additionally, methylotrophs are involved in phosphorous, nitrogen, and carbon cycling and can help reduce global warming. In this review, different aspects of the interaction between methylotrophs and host plants are discussed, including the role of methylotrophs in phosphorus acquisition, nitrogen fixation, phytohormone production, iron chelation, and plant growth promotion, and co-inoculation of these bacteria as biofertilizers for viable agriculture practices.

    New consumer awareness is shifting industry towards more sustainable practices, creating a virtuous cycle between producers and consumers enabled by eco-labelling. Eco-labelling informs consumers of specific characteristics of products and has been used to market greener products. Eco-labelling in the food industry has yet been mostly focused on promoting organic farming, limiting the scope to the agricultural stage of the supply chain, while carbon labelling informs on the carbon footprint throughout the life cycle of the product. These labelling strategies help value products in the eyes of the consumer. Because of this, decision makers are motivated to adopt more sustainable models. In the food industry, this has led to important environmental impact improvements at the agricultural stage, while most other stages in the Food Supply Chain (FSC) have continued to be designed inefficiently. The objective of this work is to define a framework showing how carbon labelling can be integrated into the design process of the FSC. For this purpose, the concept of Green Supply Chain Network Design (GSCND) focusing on the strategic decision making for location and allocation of resources and production capacity is developed considering operational, financial and environmental (CO 2 emissions) issues along key stages in the product life cycle. A multi-objective optimization strategy implemented by use of a genetic algorithm is applied to a case study on orange juice production. The results show that the consideration of CO 2 emission minimization as an objective function during the GSCND process together with techno-economic criteria produces improved FSC environmental performance compared to both organic and conventional orange juice production. Typical results thus highlight the importance that carbon emissions optimization and labelling may have to improve FSC beyond organic labelling. Finally, CO 2 emission-oriented labelling could be an important tool to improve the

    Manolo Muñoz-Espinosa

    2016-08-01

    Full Text Available The inappropriate use of agrochemicals and technologies in farming systems can cause an accelerated deterioration of agricultural and soil pollution. Thus, agriculture and livestock are becoming an environmental problem in the world, which implies the need to assess the efficiency of agricultural production systems related to sustainability. The traditional peasant system is apparently unsustainable, while farm with an integral production approach have better opportunities for development over time as they tend to sustainability. This type of farms incorporate productive alternatives that improve as a whole, the system and the livelihood of the peasants. The trends towards sustainability of farms are mainly due to a better land use. As well as, implementing systems adapted to each soil and production type to ensure profitability and persistence, achieving the highest possible agricultural productivity. The urgency to produce food for a growing population is almost a paradigm that reinforces the imperative for maximum yield per unit area, and creates a vision of the rural world aimed at increasing profit at the expense of the attributes and core values of livelihood in rural areas. It can be concluded that the integrated farming articulate various subsystems, which working together could allow higher sustainability of agricultural production practices, environmentally friendly, safeguarding the food sovereignty of the population and improving the quality of life of farmers

    2014-01-01

    Background Agricultural systems are amended ecosystems with a variety of properties. Modern agroecosystems have tended towards high through-flow systems, with energy supplied by fossil fuels directed out of the system (either deliberately for harvests or accidentally through side effects). In the coming decades, resource constraints over water, soil, biodiversity and land will affect agricultural systems. Sustainable agroecosystems are those tending to have a positive impact on natural, social and human capital, while unsustainable systems feed back to deplete these assets, leaving fewer for the future. Sustainable intensification (SI) is defined as a process or system where agricultural yields are increased without adverse environmental impact and without the conversion of additional non-agricultural land. The concept does not articulate or privilege any particular vision or method of agricultural production. Rather, it emphasizes ends rather than means, and does not pre-determine technologies, species mix or particular design components. The combination of the terms ‘sustainable’ and ‘intensification’ is an attempt to indicate that desirable outcomes around both more food and improved environmental goods and services could be achieved by a variety of means. Nonetheless, it remains controversial to some. Scope and Conclusions This review analyses recent evidence of the impacts of SI in both developing and industrialized countries, and demonstrates that both yield and natural capital dividends can occur. The review begins with analysis of the emergence of combined agricultural–environmental systems, the environmental and social outcomes of recent agricultural revolutions, and analyses the challenges for food production this century as populations grow and consumption patterns change. Emergent criticisms are highlighted, and the positive impacts of SI on food outputs and renewable capital assets detailed. It concludes with observations on policies and

The review begins with analysis of the emergence of combined agricultural-environmental systems, the environmental and social outcomes of recent agricultural revolutions, and analyses the challenges for food production this century as populations grow and consumption patterns change. Emergent criticisms are highlighted, and the positive impacts of SI on food outputs and renewable capital assets detailed. It concludes with observations on policies and incentives necessary for the wider adoption of

  17. Soil Erosion and Agricultural Sustainability

    Data drawn from a global compilation of studies support the long articulated contention that erosion rates from conventionally plowed agricultural fields greatly exceed rates of soil production, erosion under native vegetation, and long-term geological erosion. Whereas data compiled from around the world show that soil erosion under conventional agriculture exceeds both rates of soil production and geological erosion rates by up to several orders of magnitude, similar global distributions of soil production and geological erosion rates suggest an approximate balance. Net soil erosion rates in conventionally plowed fields on the order of 1 mm/yr can erode typical hillslope soil profiles over centuries to millennia, time-scales comparable to the longevity of major civilizations. Well-documented episodes of soil loss associated with agricultural activities date back to the introduction of erosive agricultural methods in regions around the world, and stratigraphic records of accelerated anthropogenic soil erosion have been recovered from lake, fluvial, and colluvial stratigraphy, as well as truncation of soil stratigraphy (such as truncated A horizons). A broad convergence in the results from studies based on various approaches employed to study ancient soil loss and rates of downstream sedimentation implies that widespread soil loss has accompanied human agricultural intensification in examples drawn from around the world. While a broad range of factors, including climate variability and society-specific social and economic contexts — such as wars or colonial relationships — all naturally influence the longevity of human societies, the ongoing loss of topsoil inferred from studies of soil erosion rates in conventional agricultural systems has obvious long-term implications for agricultural sustainability. Consequently, modern agriculture — and therefore global society — faces a fundamental question over the upcoming centuries. Can an agricultural system

    Telaga Warna and Telaga Pengilon are two volcanic lakes in the Dieng Plateau offer some unique phenomena which are interested for tourists to visit. Telaga Warna and Telaga Pengilon are located side by side in the Dieng Palteau. Those two lakes also have specific ecosystem which differ to other lakes. However as land use in the surrounding area is now gradually changing, the lake is now facing to environmental degradation. The land use in the surrounding area is for intensive agricultural which main crops are vegetable, especially potatoes. Meanwhile, the number of tourist visiting those two lakes is increasing; it may also give some impact to the lake environment. This research aims to study the impacts of agricultural practices and tourism activities to the lake environmental which lead to the environment sustainability of the lakes. The field survey was conducted to collect some data on lakes characteristics, agricultural and tourism activities. Some interviews to local people and tourists were also conducted. Some water and sediment samples were collected followed by laboratory analyses. Some secondary data from previous study was also collected. Data analysis was conducted based on qualitative and quantitative techniques. The study found that agricultural practices of potatoes plantation uses water from the Telaga Pengilon to irrigate the plant by pumping out the water using water pump and distributes the water over the plantation area. Agricultural practices lead to soil erosion, which contribute sediment to the lake carried by surface runoff. Therefore, the volume of lakes is gradually decreasing. The use of fertilizer in the agricultural practice contribute nutrient into the lake carried by surface runoff, leading to the eutrophication, due to the excess used of fertilizer. The study concludes that agricultural practices and tourism activities have some positive economic impacts to the local community, however it also give some adverse affects on the lakes

    Olive (Olea europaea) is the dominant agriculture plantation in Spain and its main product, olive oil, is vital to the economy of Mediterranean countries. Given the extensive surface dedicated to olive plantations, olive groves can potentially sequester large amounts of carbon and contribute to mitigate climate change. Their potential for carbon sequestration will, however, largely depend on the management and irrigation practices in the olive grove. Although soil respiration is the main path of C release from the terrestrial ecosystems to the atmosphere and a suitable indicator of soil health and fertility, the interaction of agricultural management practices with irrigation regimes on soil CO2 fluxes have not been assessed yet. Here we investigate the influence of the presence of herbaceous cover, use of artificial fertilizers and their interaction with the irrigation regime on the CO2 emission from the soil to the atmosphere. For this, the three agricultural management treatments were established in replicated plots in an olive grove in the SE of Spain: presence of herbaceous cover ("H"), exclusion of herbaceous cover by using herbicides ("NH"), and exclusion of herbaceous cover along with addition of artificial fertilizers (0.55 kg m-2 year-1 of N, P, K solid fertilizer in the proportion 20:10:10, "NHF"). Within each management treatment, three irrigation regimes were also implemented in a randomized design: no-irrigation ("NO") or rain fed, full irrigation (224 l week-1 per olive tree, "MAX"), and a 50% restriction (112 l week-1 per olive tree, "MED"). Soil respiration was measured every 2-3 weeks at 1, 3, and 5 meters from each olive tree together with soil temperature and soil moisture in order to account for the spatial and seasonal variability over the year. Soil respiration was higher when herbaceous cover was present compared to the herbaceous exclusion, whereas the addition of fertilizer did not exert any significant effect. Although the different

    The aim of this review is to generate awareness and understand the importance of earthworms in sustainable agriculture and effect of pesticides on their action. The natural resources are finite and highly prone to degradation by the misuse of land and mismanagement of soil. The world is in utter need of a healthy ecosystem that provides with fertile soil, clean water, food and other natural resources. Anthropogenic activities have led to an increased contamination of land. The intensification of industrial and agricultural practices chiefly the utilization of pesticides has in almost every way made our natural resources concave. Earthworms help in a number of tasks that support many ecosystem services that favor agrosystem sustainability but are degraded by exhaustive practices such as the use of pesticides. The present review assesses the response of earthworm toward the pesticides and also evaluates the relationship between earthworm activity and plant growth. We strictly need to refresh and rethink on the policies and norms devised by us on sustainable ecology. In an equivalent way, the natural resources should be utilized and further, essential ways for betterment of present and future livelihood should be sought.

  3. Agricultural innovations for sustainable crop production intensification

    Full Text Available Sustainable crop production intensification should be the first strategic objective of innovative agronomic research for the next 40 years. A range of options exist (often very location specific for farming practices, approaches and technologies that ensure sustainability, while at the same time improving crop production. The main challenge is to encourage farmers in the use of appropriate technologies,  and  to  ensure  that  knowledge  about  sound  production  practices  is  increasingly accepted and applied by farmers. There is a huge, but underutilized potential to link farmers’ local knowledge with science-based innovations, through favourable institutional arrangements.  The same  holds  for  the  design,  implementation  and  monitoring  of  improved  natural  resource management  that  links  community  initiatives  to  external  expertise.  It is also suggested that a comprehensive effort be undertaken to measure different stages of the innovation system, including technological adoption and diffusion at the farm level, and to investigate the impact of agricultural policies on technological change and technical efficiency. This paper provides a brief review of agronomic management practices that support sustainable crop production system and evidence on developments  in the selection of crops and cultivars; describes farming systems for crop which take a predominantly ecosystem approach; discusses the scientific application of ecosystem principles for the management of pest and weed populations; reviews the  improvements in fertilizer and nutrient management that explain productivity growth; describes the benefits and constraints of irrigation technologies; and suggests a way forward. Seven changes in the context for agricultural development are proposed that heighten the need to examine how innovation occurs in the agricultural sector.

    The disposal of olive mill wastewater (OMW) is a serious environmental issue for the Mediterranean countries. However, there is still no common European legislation on the management and the re-use of OMW in agriculture, in the frame of sustainable crop management and the standards for the safe OMW disposal and re-use are left to be set by each EU country, individually. This review paper presents the most effective and sustainable practices for OMW, (treatment, application and management), which can maximize the benefits of OMW on crops and soils, while minimizing the potential hazards for public health, thus promoting environmental sustainability. The findings of this synthetic work suggest that there is enough information and proven sustainable practices to go ahead with the initial formulation of a new consensual framework, environmentally acceptable, socially bearable and economically viable, that could hopefully help to set the standards for the re-use of olive mil wastewater and can lead to a common EU policy on the management and re-use of OMW.

    The flood events present during the last years in different basins of the Colombian territory have raised questions on the sensitivity of the regions and if this regions have common features. From previous studies it seems important features in the sensitivity of the flood process were: land cover change, precipitation anomalies and these related to impacts of agriculture management and water management deficiencies, among others. A significant government investment in the outreach activities for adopting and promoting the Colombia National Action Plan on Climate Change (NAPCC) is being carried out in different sectors and regions, having as a priority the agriculture sector. However, more information is still needed in the local environment in order to assess were the regions have this sensitivity. Also the continuous change in one region with seasonal agricultural practices have been pointed out as a critical information for optimal sustainable development. This combined spatio-temporal dynamics of crops cycle in relation to climate change (or variations) has an important impact on flooding events at basin areas. This research will develop on the assessment and optimization of the aggregated impact of flood events due to determinate the spatio-temporal dynamic of changes in agricultural management practices. A number of common best agricultural practices have been identified to explore their effect in a spatial hydrological model that will evaluate overall changes. The optimization process consists on the evaluation of best performance in the agricultural production, without having to change crops activities or move to other regions. To achieve this objectives a deep analysis of different models combined with current and future climate scenarios have been planned. An algorithm have been formulated to cover the parametric updates such that the optimal temporal identification will be evaluated in different region on the case study area.

    Full Text Available Agriculture is one of the most important economic activities in each country or area, as it is in close correlation with all other the other economic activities, in a whole which must be structured so as to achieve a more efficient planning and organization of the territory. The practice of a traditional agriculture, based on industrialization, affects the natural environment through emissions of pollutants, waste and deforestation which together affects biodiversity. Green Agriculture suppose to empower managers to widespread the use of fertilizers, to improve the crop rotation, to realize a more efficient water consumption, to improve the storage methods and the supply chain of products. Agricultural policies are closely interrelated with environmental policies as agricultural activities have a considerable influence on the environment. The efficiency of agricultural policies is reflected in monetary transfers between agriculture and other economic sectors, in the costs due to the reallocation of the resources between different agricultural and non-agricultural activities and in the realized gains. Currently there is a constant concern of the governments for the transition to a green agriculture, and most countries recognize the importance of achieving sustainable economic development.

    As global populations continue to increase, agricultural productivity will be challenged to keep pace without overtaxing important environmental resources. A dynamic and integrated approach will be required to solve global food insecurity and position agriculture on a trajectory toward sustainability. Genetically modified (GM) crops enhanced through modern biotechnology represent an important set of tools that can promote sustainable agriculture and improve food security. Several emerging biotechnology approaches were discussed in a recent symposium organized at the 13th IUPAC International Congress of Pesticide Chemistry meeting in San Francisco, CA, USA. This paper summarizes the innovative research and several of the new and emerging technologies within the field of agricultural biotechnology that were presented during the symposium. This discussion highlights how agricultural biotechnology fits within the context of sustainable agriculture and improved food security and can be used in support of further development and adoption of beneficial GM crops.

The principle of sustainable agriculture is to cover the human needs for food without damage to the environment. The aim of the article was to research the farmers' awareness of the principle of sustainable agriculture and balanced fertilization and their influence on the environment. Among 100 farmers of the Tczew district (Poland) there was done questionnaire research on the determination rates of nitrogen fertilizers and on the regulation of fertilizers usage in Poland. Most of farmers declared a good knowledge of good agricultural practices and of balanced fertilization and the awareness of threats issuing from their activities. At the same time in Poland since the announcement of the Nitrate Directive of the former European Common Market (1992) up till now (2013) the application of nitrogen fertilizers doubled and the yield of wheat increased only by 15%, which means the increase of environmental burden with this chemical element.

    1999-01-01

    Future agricultural and rural development is, to a large extent, influenced by the projected food needs of 2.5 billion people expected to swell the world population by 2020. This increase will require more food in general and, in view of recent experience in East Asia, more animal products. To achieve this increase will require judicious use of resources, and trade, especially in those countries where natural resources are insufficient to support food production. Achieving food sufficiency in a sustainable manner is a major challenge for farmers, agro-industries, researchers and governments. The latter play an important role as many of the farmers' choices are, to a large extent, directed by government or supra-government, often through macro- and micro-economic policy. In many countries the economic, environmental, trade and agricultural policies have not been conducive to an agricultural development that is risk-free with respect to the environment, animal welfare or public health. The recent decline of government support in agriculture forced farmers in Western countries to think about more risk adverse agricultural practices and more efficient production systems. On the other hand, many countries in Eastern Europe and the former Soviet Union, as well as other developing countries, are still going through a painful process of adjustment to new market conditions. International banks and development agencies have a mandate to help developing countries, but are somewhat restricted both by needing to work directly with governments and by their perceived dogmatic approach to development. Changing policies do, now and in the future, also affect the development of animal disease control programmes, including the control of parasitic diseases. On the one hand there is an increasing interest in risk-free control practices, and on the other hand a demand for greater regulatory control over the production process. As parasitic diseases of animals are closely linked to the

    2011-12-01

    Full Text Available The sustainability of conventional agriculture in Bangladesh is under threat from the continuous degradation of land and water resources, and from declining yields due to indiscriminate use of agro-chemicals. Government is pursuing efforts to promote sustainable agriculture with emphasis on better use of on-farm resources and the reduction of external inputs. This paper presents four dimensions of agricultural sustainability as productivity, environmental stability, economical profitability, and social and economic equity. Six characters were selected to evaluate sustainability. Significant differences were found between the two systems (conventional and sustainable agriculture in crop diversification, soil fertility management, pests and diseases management, use of agro-chemicals and environmental issues. However, no significant variations were found in other indicators such as land-use pattern, crop yield and stability, risk and uncertainties, and food security. Although crop yield and financial return were found to be slightly higher in the conventional system, the economic return and value addition per unit of land did not show any difference. It can be suggested that sustainable agriculture has a tendency towards becoming environmental, economically and socially more sound than conventional agriculture, as it requires considerably less agro-chemicals, adds more organic matter to the soil, provides balanced food, and requires higher local inputs without markedly compromising output and financial benefits. Broad-policy measures, including the creation of mass awareness of adverse health effects of agrochemical-based products, are outlined for the promotion of sustainable agriculture.

    Full Text Available Bioelectrochemical systems (BES are a newly emerged technology for energy-efficient water and wastewater treatment. Much effort as well as significant progress has been made in advancing this technology towards practical applications treating various types of waste. However, BES application for agriculture has not been well explored. Herein, studies of BES related to agriculture are reviewed and the potential applications of BES for promoting sustainable agriculture are discussed. BES may be applied to treat the waste/wastewater from agricultural production, minimizing contaminants, producing bioenergy, and recovering useful nutrients. BES can also be used to supply irrigation water via desalinating brackish water or producing reclaimed water from wastewater. The energy generated in BES can be used as a power source for wireless sensors monitoring the key parameters for agricultural activities. The importance of BES to sustainable agriculture should be recognized, and future development of this technology should identify proper application niches with technological advancement.

    Full Text Available Sustainability assessment is a mainstream business activity that demonstrates the link between the organization’s strategy and commitment to a sustainable global economy. Sustainability indicators describe the environmental, social, economic and governance performance of Small and Medium‑sized Businesses/Enterprises (SMB/SME. Unfortunately, their implementations in the Czech Republic show a low level of engagement in sustainability assessment. The paper presents the results of the authors’ research in sustainability assessment of SMB/SMEs in the agriculture sector of the Czech Republic. An appropriate set of key performance indicators (KPIs in four dimensions (economy, environment, social and governance was developed to suit the SMB/SMEs sustainability assessment in the agriculture sector. A set of KPIs is proposed to help SMB/SMEs to avoid the barriers of sustainability assessment. These indicators are based mainly on Sustainability Assessment of Food and Agriculture, Global Reporting Initiatives Frameworks and on current research state‑of‑the‑art. They have been created following the analysis of a number of agricultural enterprises over the world, particularly within European countries.

    2017-04-01

    The concept of sustainable development has evolved from a mere perception for the protection of the environment, to a holistic approach, seeking to preserve not only the environment, but also to achieve sustainability in economics and social wellbeing. Globally, there is a major challenge to face in the agricultural sector: to produce more food, feed and other raw materials to satisfy the increasing demand of a growing population, whilst also contributing to economic prosperity, climate change mitigation / adaptation, social wellbeing and preserving natural capital such as soil, water, biodiversity and other ecosystem services. Nowadays, conventional approaches to agriculture are under threat. A more productive and resource efficient agriculture that integrates natural resource protection into its approach will help to meet all these challenges, enabling us to have more of everything - more food, more feed, more non-food crops, more biodiversity and natural habitats - while also reducing greenhouse gas emissions. In this context, INSPIA is an innovative approach that has worked since 2013 towards demonstration that sustainable productive agriculture is possible thanks to the implementation of a host of best management practices (BMPs) capable of delivering the above achievements. The purpose on INSPIA is to make visible with European decision makers that a sustainable and productive agricultural model exists in a small scale in Europe and that wider dissemination is possible with enabling legislation. INSPIA is demonstrating sustainable agriculture through the implementation of BMPs and the measurement and monitoring of a set of defined indicators (economic, social and environmental ones). INSPIA promotes sustainable practices that protect biodiversity, soils and water and contribute towards maintaining ecosystems services. This holistic sustainable system of productive agriculture is based on the combination of Conservation Agriculture (CA) and Integrated Pest

    Full Text Available In the present article, an attempt was made to assess the sustainability of agricultural holdings with diff erent directions of production. Agricultural holdings in the Podlaskie voivodeship registered in the FADN system in 2011–2012 were investigated. Assessment accounted for agroecological indicators (share of permanent grasslands, share of cereals in crops, soil coverage with vegetation, stock density and economic indicators (profi tableness of land and labor. Analysis was conducted according to a classifi cation into agricultural holding types: fi eldcrops, dairy cattle, and granivores. Fieldcrop and granivore holdings achieved more favourable environmental sustainability indicators. Holdings specializing in dairy cattle breeding posed a threat to the natural environment, mainly due to their excessive stock density. Economic sustainability assessment showed that granivore holdings were assessed most favorably. In these holdings, holding income per full-time worker was 37% greater than in fi eldcrop holdings and 57% greater than in dairy cattle holdings.

    Full Text Available Yacht tourism has become an important asset for the countries which consider tourism as a means of development due to its environment awareness, national and international investments, the volume of business, employment opportunities, foreign exchange income, socio-economic and socio-cultural impact, and an increasing number of investments and incentives for yacht tourism have made and used in a number of countries. In the presence of such rapid developments, the environmental damage caused by yacht tourism has been of importance for coastal countries, and action plans and special projects involving many countries have been developed in order to enhance the awareness of the sustainability of yacht tourism. Given that environment is not a limited source, it is blatant that national or international sustainable tourism practices have been essential for coastal countries and environmental threats are now so severe that they cannot be overlooked. The purpose of the study is to discuss sustainable tourism practices as a part of the measures to eliminate the negative impacts of yacht tourism and provide relevant suggestions.

    Fresh water scarcity is a global problem with local solutions. Agriculture is one of many human systems threatened by water deficits, and faces unique supply, demand, quality, and management challenges as the global climate changes and population grows. Sustainable agricultural water management is paramount to protecting global economies and ecosystems, but requires different approaches based on environmental conditions, social structures, and resource availability. This research compares water used by conservation agriculture in temperate and tropical agroecosystems through data collected from operations growing strawberries, grapes, tomatoes, and pistachios in California and corn and soybeans in Colombia. The highly manipulated hydrologic regime in California has depleted water resources and incited various adaptive management strategies, varying based on crop type and location throughout the state. Operations have to use less water more efficiently, and sometimes that means fallowing land in select groundwater basins. At the opposite end of the spectrum, the largely untouched landscape in the eastern plains of Colombia are rapidly being converted into commercial agricultural operations, with a unique opportunity to manage and plan for agricultural development with sustainability in mind. Although influenced by entirely different climates and economies, there are some similarities in agricultural water management strategies that could be applicable worldwide. Cover crops are a successful management strategy for both agricultural regimes, and moving forward it appears that farmers who work in coordination with their neighbors to plan for optimal production will be most successful in both locations. This research points to the required coordination of agricultural extension services as a critical component to sustainable water use, successful economies, and protected environments.

    Full Text Available Biodynamic agriculture is undoubtedly the oldest organized agricultural movement in the world. It is considered as an organic agricultural farming approach and determined as the oldest organized alternative agricultural movement in the world. In 1924 Rudolf Steiner – an Austrian natural scientist and philosopher, carried out a series of eight lectures in Koberwitz, currently Kobierzyce- Poland, where he formulated his visions on changes in agriculture and revealed his spiritual and scientific concepts about the connection between nature and agriculture by determining the important role of agriculture for the future of humanity and thus he became known as “the father of anthroposophy”. The great ecological effect of the application of the biodynamic agriculture is expressed in soil preservation and preservation of the living organisms in the soil, as well as maintenance of the natural balance in the vegetable and animal kingdom.

    Indian agriculture has achieved remarkable success in the food grain production due to inception of 'rainbow revolution', which made the country self-sufficient in food production. Sustainable agriculture (SA) is an ongoing process, in which people take actions leading to development of agriculture that meets their current needs without compromising the ability of future generations to meet their needs. It advocates avoiding all those actions, which reduce the ability of future generations to meet out the present generations. It is based on the optimal interaction between clean environment, healthy economy, and vital society by avoiding trade-off of problems to other regions on to the future. Moreover, sustainable agriculture is the function of people's progress and nature's capacity. In fact, SA commits us to considering the long-term effect and to recognize our place within the ecosystem. It encourages a continuous reflection on the implications of human activity on the ecosystem. Empirical evidences shows that in the race of self-sufficiency in food grain production, we compromised a lot on social and environmental fronts. The aftermath of green revolution is not so sustainable as it showed reverse side too, in the form of environmental degradation and ecological imbalances. Such threats have led to the need for promoting sustainable development in agriculture. Due to several unsustainable activities which resulted in resource degradation in the form of top soil loss, ground water depletion and forest degradation. The average soil loss is estimated to be over 16 tonnes/ha/year. The ground water depletion resulted in several blocks as 'grey blocks' and 'dark blocks'. This happened mainly due to increase in number of tube-wells and free supply of electricity making the cost of pumping water very low. Rate of human induced land degradation is very high. Out of total geographical area of 329.0 million ha, 187 million ha (57.0 %) are reported to have degraded, of

  16. Challenges for Sustainable Land Management through Climate-Smart Agriculture

    2017-04-01

    There are increasing pushes for agricultural land management to be both sustainable and climate-smart (in terms of increasing productivity, building resilience to climate change and enhancing carbon storage). Climate-smart agriculture initiatives include conservation agriculture, based on minimum soil disturbance, permanent soil cover and crop rotation, and agroforestry. Such efforts address key international goals of the United Nations Convention to Combat Desertification (UNCCD) and United Nations Framework Convention on Climate Change (UNFCCC), but as yet have not seen widespread uptake. Based on analyses of different project interventions from across a range of southern African countries, we outline the inter-related challenges that are preventing adoption of climate-smart agriculture initiatives. We then identify routes to building multi-stakeholder partnerships and empowering communities through participatory monitoring with the aim of increasing uptake of such sustainable land management practices. Good practice examples remain largely restricted to local-level project interventions with significant donor (or private-sector) support, aligned to short-term community priorities relating to access to inputs or reduced labour requirements. Scaling-up to district- and national-level initiatives is yet to be widely successful due to problems of: limited policy coherence; a lack of communication between stakeholders at different levels; and limited understanding of long-term benefits associated with changes in agricultural practices. We outline opportunities associated with improved communication of climate information, empowerment of district-level adaptation planning and diversification of agricultural livelihood strategies as key routes to guide farmers towards more sustainable, and climate-smart, land management practices. Recent experiences in Malawi, which has experienced significant floods and an El Niño drought year in the last two years, are used to

    Water is a renewable but limited resource. Most human use of freshwater resources is for agriculture, and global water demand for agriculture is increasing because of the growth in food demand, driven by increasing population and changing diets. Hence, measuring the pressure exerted by agriculture on freshwater sources is a key issue. The sustainability of water use depends on the water source renewability rate: the water use is not sustainable (depleting the water storage) where/when it exceeds the renewable freshwater availability. In this study, we explore the sustainability of rain and irrigation water use for the production of nine major crops, globally at a 5'x5' spatial resolution. We split the crop water use into soil moisture (from rainfall) and irrigation, with, for the first time, separating ground- and surface-water sources, which is a key distinction because the renewability of these two water sources can be very different. In order to physically quantify the extent to which crop water use is sustainable, we measure the severity of the source depletion as the number of years required for the hydrological cycle to replenish the water resource used by the annual crop production, namely the Water Debt. This newly developed indicator allows one to compare the depletion level of the three water sources at a certain location for a specific crop. Hence, we mapped, for each crop, the number of years required to replenish the water withdrawn from soil-, surface- and ground-water resources. Each map identifies the hotspots for each water source, highlighting regions and crops that threaten most the water resource. We found that the water debt with soil moisture is heterogeneous in space but always lower than one year indicating a non-surprising sustainability of rain-fed agriculture. Rice and sugarcane make the largest contribution to global soil moisture depletion. Water debt in surface water is particularly high in areas of intense wheat and cotton production

    Intensive agriculture, which depends on unsustainable levels of agrochemical inputs, is environmentally harmful, and the expansion of these practices to meet future needs is not economically feasible. Other options should be considered to meet the global food security challenge. The plant microbiome has been linked to improved plant productivity and, in this microreview, we consider the endosphere - a subdivision of the plant microbiome. We suggest a new definition of microbial endophyte status, the need for synergy between fungal and bacterial endophyte research efforts, as well as potential strategies for endophyte application to agricultural systems. © 2016 THE AUTHORS.

  20. Routing of biomass for sustainable agricultural development

    International Nuclear Information System (INIS)

    Suhaimi Masduki; Aini Zakaria

    1998-01-01

    Photosynthetically derived biomass and residues, including waste products from food processing industries are renewable. They accumulate every year in large quantities, causing deterioration to the environment and loss of potentially valuable resources. The conserved energy is potentially convertible; thermodynamically the energy can be tapped into forms which are more amenable for value added agricultural applications or for other higher value products such as chemicals or their feedstocks. The forms and types in which this biomass has to be modified for the intended use depend on the costs or the respective alternatives. Under current situations, where chemical feedstocks are available in abundance at very competitive prices, biomass is obviously more suitably placed in the agro-industrial sector. Recycling of the biomass or residues into the soil as biofertilizers or for some other uses for agricultural applications requires less intense energy inputs for their improvements. Highly efficient biological processes with microorganisms as the primary movers in the production of the desired end products indeed require less capital costs than in most other industrial entities. In this paper, the various processes, which are potentially valuable and economically feasible in the conversion of biomass and residues for several products important in the agricultural sector, are described. Emphasis is given to the approach and the possible permutations of these processes to arrive at the desired good quality products for sustainable agricultural development. (Author)

    The changing climate leads to uncertainties concerning the sustainability of certain agricultural resources, and with the additional stresses of an increasing global population, uncertainty in food security will greatly increase. To adhere to future food demands in the face of this changing climate, perennial agriculture has been a proposed solution. However, it is equally important to assure that perennial agriculture is not negatively affecting the climate in exchange for this proposed more robust food source. We chose to examine the interactions between perennial and annual agricultural crops by focusing on the efficiency of exchanges with the atmosphere. This is done using the omega decoupling factor for 4 different sites as a way of quantifying the contributions of radiation and stomatal conductance over the resulting water and carbon cycles. This gives us an indication of how the plant canopy is interacting with, and influencing the local microclimate. Ultimately, this should give us an indication of the ability of perennial crops to aid in the climate mitigation process. We hypothesized that the perennial site chosen would have omega values more similar to the omega values of a natural grassland rather than an annual crop site. Using AmeriFlux towers to determine the canopy values needed to calculate the omega decoupling factor, we focused on the Kernza perennial crops being grown at the Land Institute in Salina, Kansas (KLS), in comparison to a natural grassland in Manhattan, Kansas (KON), a typical land cover model in Lawrence, Kansas (KFS), and an annual crop site in Lamont, Oklahoma (ARM). These results will allow us to move forward in the investigation of perennial crops as a sustainable food source.

    Increasing crop yields can provide food, animal feed, bioenergy feedstocks and biomaterials to meet increasing global demand; however, the methods used to increase yield can negatively affect sustainability. For example, application of excess fertilizer can generate and maintain high yields but also increases input costs and contributes to environmental damage through eutrophication, soil acidification and air pollution. Improving crop nutrient efficiency can improve agricultural sustainability by increasing yield while decreasing input costs and harmful environmental effects. Here, we review the mechanisms of nutrient efficiency (primarily for nitrogen, phosphorus, potassium and iron) and breeding strategies for improving this trait, along with the role of regulation of gene expression in enhancing crop nutrient efficiency to increase yields. We focus on the importance of root system architecture to improve nutrient acquisition efficiency, as well as the contributions of mineral translocation, remobilization and metabolic efficiency to nutrient utilization efficiency. © 2017 Institute of Botany, Chinese Academy of Sciences.

    Full Text Available Sustainability and agricultural finance are two important issues attracting attention from industry and academia. This research adopts an in-depth case study methodology to investigate the agricultural finance initiatives of Alibaba Group, and explores how the agricultural finance practices of an e-commerce platform facilitate its sustainability goal. A reference framework is proposed to prove the adoption of agricultural finance. The influence of three moderating variables, namely, IT support, financial attractiveness, and cooperation with other entities, is analyzed. We find that advanced IT support and financial attractiveness are two indispensable enablers for agricultural finance initiatives, and collaboration with other entities is necessary in adopting agricultural supply chain finance.

    2014-12-01

    Full Text Available Sustainable water management (SWM requires allocating between competing water sector demands, and balancing the financial and social resources required to support necessary water systems. The objective of this review is to assess SWM in three sectors: urban, agricultural, and natural systems. This review explores the following questions: (1 How is SWM defined and evaluated? (2 What are the challenges associated with sustainable development in each sector? (3 What are the areas of greatest potential improvement in urban and agricultural water management systems? And (4 What role does country development status have in SWM practices? The methods for evaluating water management practices range from relatively simple indicator methods to integration of multiple models, depending on the complexity of the problem and resources of the investigators. The two key findings and recommendations for meeting SWM objectives are: (1 all forms of water must be considered usable, and reusable, water resources; and (2 increasing agricultural crop water production represents the largest opportunity for reducing total water consumption, and will be required to meet global food security needs. The level of regional development should not dictate sustainability objectives, however local infrastructure conditions and financial capabilities should inform the details of water system design and evaluation.

    2017-01-01

    Maintaining the long-term sustainability of human and natural systems across agricultural landscapes requires an integrated, systematic monitoring system that can track crop productivity and the impacts of agricultural intensification on natural resources. This study presents the design and practical implementation of a monitoring framework that combines satellite observations with ground-based biophysical measurements and household surveys to provide metrics on ecosystem services and agricultural production at multiple spatial scales, reaching from individual households and plots owned by smallholder farmers to 100-km 2 landscapes. We developed a set of protocols for monitoring and analyzing ecological and agricultural household parameters within two 10 × 10-km landscapes in Rwanda, including soil fertility, crop yield, water availability, and fuelwood sustainability. Initial results suggest providing households that rely on rainfall for crop irrigation with timely climate information and improved technical inputs pre-harvest could help increase crop productivity in the short term. The value of the monitoring system is discussed as an effective tool for establishing a baseline of ecosystem services and agriculture before further change in land use and climate, identifying limitations in crop production and soil fertility, and evaluating food security, economic development, and environmental sustainability goals set forth by the Rwandan government.

    To meet the growing global demand for food and bioenergy, agricultural production must nearly double by 2050, placing additional pressures on the environment and the society. Thus, how to efficiently use limited land, water, and nutrient resources to produce more food with low pollution (MoFoLoPo) is clearly one of the major challenges of this century. The increasingly interconnected global market provides a great opportunity for reallocating crop production to the countries and regions that use natural resources more efficiently. For example, it is estimated that optimizing the allocation of crop production around the world can mitigate 41% of nitrogen lost to the environment. However, higher efficiency in nutrients use does not necessarily lead to higher efficiency in land use or water use. In addition, the increasing share of international trade in food supply may introduce additional systemic risk and affect the resilience of global food system. Using the data/indicator from a Sustainable Agriculture Matrix and an international trade matrix, we developed a simple model to assess the trade-offs of international trade considering resource use efficiencies (including water, land, nitrogen, and phosphorus), economic costs and benefits, and the resilience of food system.

    In a sustainable system, the soil is viewed as a fragile and living medium that must be protected and nurtured to ensure its long-term productivity and stability. However, due to high demand for food brought about by high population as well as the decline in agricultural lands, the soil is being exploited beyond its limit thus, leading to poor or sick soils. Sound soil management practices in the Philippines is being reviewed. The technologies, including the advantages and disadvantages are hereby presented. This includes proper cropping systems, fertilizer program, soil erosion control and correcting soil acidity. Sound soil management practices which conserve organic matter for long-term sustainability includes addition of compost, maintaining soil cover, increasing aggregates stability, soil tilt and diversity of soil microbial life. A healthy soil is a key component to sustainability as a health soil produce healthy crop plants and have optimum vigor or less susceptible to pests. (author)

    Full Text Available Trichoderma spp. are well-known bio-control agents which promote the plant growth and suppress the pathogen infection. The beneficial effects are attributed to the production of phytohormones, antibiotics, siderophores and secondary metabolites (SM. Trichodermin and Harzianum A, SMs have documented anti-fungal activities as well. Tri5 gene encodes for trichodiene synthase (TS contains a terpene fold and involved at the initial step of the biosynthetic pathway of these molecules. Furthermore, domain analysis of proteins from diverse organisms showed that the terpene fold has functional diversity with diverse applications in agriculture, medicine and applied biotechnology. These proteins can be classified into single and multi-domains based on their structures. It was observed that multi-domain proteins carry additional helices which may regulate the catalytic efficiency. Further, activity enhancing mutations with potentially higher catalytic activities were screened. In an offshoot to the above work, we have analyzed binding of Trichodermin with the 25S rRNA that constitutes the petidyltransferase centre (PTC. The trichodermin resistance protein (60S ribosomal protein L3 was reported to overcome the inhibitory effects of trichothecene compounds. Normal mode analysis and MD of trichodermin resistance protein and 25S consisting of PTC showed that the W-finger region of the protein may move towards 25S rRNA and may block the binding pocket of the trichodermin. These results may lead to develop strategies for higher TS activity and the mechanism of action of these molecules involved in plant-microbe interactions. These may be further exploited for enhancing the efficiency of these biotechnological agents used in sustainable agriculture.

Maintaining high quality of agricultural products with lower environmental impacts through a sustainable economic viability and life satisfaction of farmers and community are important factors helping to meet sustainable agriculture. Human resources are playing key role in directing the community toward sustainable development. The trend of improving the human development index in Malaysia is highest in the East Asia and the Pacific, high human development countries and the world, since 2000. Precision agriculture is providing strong tools to achieve sustainable agriculture. Different types of sensors, positioning and navigation systems, GIS, software and variable rate technology are well known components of precision agriculture. Drones and robots are promising tools that enabling farmers and managers to collect information or perform particular actions in remote areas or tough conditions. According to a survey, forestry and timber, rubber production and oil palm estates are three main agricultural divisions that precision agriculture may improve the productivity in respect to area of cropland/worker. Main factors affecting the adoption of precision agriculture in Malaysia are: a) Political and legal supports, b) Decision support systems and user interfaces c) Experienced research team works d) National educational policy e) Success in commercialization of precision agriculture system.

  2. Modeling large-scale adoption of intercropping as a sustainable agricultural practice for food security and air pollution mitigation around the globe

    The fast-growing world population will impose a severe pressure on our current global food production system. Meanwhile, boosting crop yield by increasing fertilizer use comes with a cascade of environmental problems including air pollution. In China, agricultural activities contribute to 95% of total ammonia emissions. Such emissions are attributable to 20% of the fine particulate matter (PM2.5) formed in the downwind regions, which imposes severe health risks to the citizens. Field studies of soybean intercropping have demonstrated its potential to enhance crop yield, lower fertilizer use, and thus reduce ammonia emissions by taking advantage of legume nitrogen fixation and enabling mutualistic crop-crop interactions between legumes and non-legume crops. In our work, we revise the process-based biogeochemical model, DeNitrification-DeComposition (DNDC) to capture the belowground interactions of intercropped crops and show that with intercropping, only 58% of fertilizer is required to yield the same maize production of its monoculture counterpart, corresponding to a reduction in ammonia emission by 43% over China. Using the GEOS-Chem global 3-D chemical transport model, we estimate that such ammonia reduction can lessen downwind inorganic PM2.5 by up to 2.1% (equivalent to 1.3 μg m-3), which saves the Chinese air pollution-related health costs by up to US$1.5 billion each year. With the more enhanced crop growth and land management algorithms in the Community Land Model (CLM), we also implement into CLM the new parametrization of the belowground interactions to simulate large-scale adoption of intercropping around the globe and study their beneficial effects on food production, fertilizer usage and ammonia reduction. This study can serve as a scientific basis for policy makers and intergovernmental organizations to consider promoting large-scale intercropping to maintain a sustainable global food supply to secure both future crop production and air quality.

  3. Agroforestry—The Next Step in Sustainable and Resilient Agriculture

    Full Text Available Agriculture faces the unprecedented task of feeding a world population of 9 billion people by 2050 while simultaneously avoiding harmful environmental and social effects. One effort to meet this challenge has been organic farming, with outcomes that are generally positive. However, a number of challenges remain. Organic yields lag behind those in conventional agriculture, and greenhouse gas emissions and nutrient leaching remain somewhat problematic. In this paper, we examine current organic and conventional agriculture systems and suggest that agroforestry, which is the intentional combination of trees and shrubs with crops or livestock, could be the next step in sustainable agriculture. By implementing systems that mimic nature’s functions, agroforestry has the potential to remain productive while supporting a range of ecosystem services. In this paper, we outline the common practices and products of agroforestry as well as beneficial environmental and social effects. We address barriers to agroforestry and explore potential options to alter policies and increase adoption by farmers. We conclude that agroforestry is one of the best land use strategies to contribute to food security while simultaneously limiting environmental degradation.

    the Land and Water Development Division (AGL), FAO, and the national action plans for soil productivity improvement under the Soil Fertility Initiative for sub-Saharan countries, PRs are considered as potentially important locally available P sources. AGL has instituted several studies on the agro-economic assessment of PRs for direct application in selected countries. Results of practical utility and policy guidelines can be drawn from these studies. Several organizations have conducted extensive research on the utilization of indigenous PR deposits in tropical soils in Latin America, Africa, Asia and elsewhere. In the past decade, considerable progress has been made in the utilization of PR sources for direct application in agricultural cropping systems worldwide. A wealth of information is now available but scattered in several publications. Recognizing the need for the wider dissemination of the available information, the Joint FAO/ IAEA Division of Nuclear Techniques in Food and Agriculture together with the AGL convened a Consultants' Meeting in Vienna in November 2001 in order to review advances in this fi eld of research and development, and to elaborate a proposal for the production of this technical bulletin

    Full Text Available Noise has become a serious environmental problem and there are demands for alternative sustainable materials which capable to reduce the noise level at various frequency ranges. Therefore, the aim of this research is to study the potential of turning the agricultural waste and waste paper into a sound absorption panel. For the purpose of this study, combination of two materials was under studied; coconut coir fibre from agriculture waste and shredded waste paper from the office. There were two main objective of the research; first is to develop absorption panels from coconut coir powder that available locally with a combination of shredded paper at different percentage of mixture. Second objective is to identify the absorption rate of the panels. The study encompasses the fabrication of the particle board using the coconut husk powder mix with shredded waste paper and using the gypsum powder as the binder for the two materials. Four acoustic panels of size 0.5m x 0.5m and 0.012 m thick were fabricated with different mix ratio; 25% of coconut coir powder mixed with 75% of shredded waste papers for sample 1, 50% both of the material for sample 2, 75% of coconut coir powder mixed with 25% of shredded waste paper for sample 3, and lastly 100% of coconut coir powder for sample 4. The absorption coefficient of the panels was tested in a reverberation chamber and in accordance with ISO 354:1985 standards. Based on the results, sample 1 gave the highest absorption coefficient compared to sample 2, 3 and 4. It can be concluded that the acoustic panel made from a mixture of 25% coconut coir powder with 75% shredded waste paper provided higher absorption coefficient compared to the performance of the other samples. This might be caused by the size of the coir powder which is very small, creating less void space in between the panel and thus causing it to absorb less sound. Since sound absorption is very much affected by the availability of void space of

    Full Text Available The paper is focused on the evaluation of economic, social and environmental challenges of sustainable agriculture. The selected indicators of the economic challenges of sustainable agriculture imply that agriculture in Slovakia is not in long term be able to ensure competitiveness in the European market, gross agricultural output is characterized by a faster decline in animal production than in crop production and the value of import of agri-food commodities is higher than the value of export. According to selected indicators of social challenges of sustainable agriculture the number of persons working in agriculture has decreasing tendency in last years. The evaluation of selected indicators of environmental challenges of sustainable agriculture implies that area of organic agriculture is the most widely applied sub-measure within the measure agri-environmental payments. For ensuring the balance of the three mentioned dimensions of sustainable agriculture is necessary to increase of local production and consumption of local products, to ensure the protection of nature and landscape, to ensure rural development and to increase the employment opportunities in countryside.

  9. GM Crops, Organic Agriculture and Breeding for Sustainability

    Directory of Open Access Journals (Sweden)

    Salvatore Ceccarelli

    2014-07-01

    Full Text Available The ongoing debate about the use of genetically-modified (GM crops in agriculture has largely focused on food safety and genetic contamination issues. Given that the majority of GM crops have been produced to respond to the problem of crop yield reductions caused by diseases, insects and weeds, the paper argues that in those cases, the currently used GM crops are an unstable solution to the problem, because they represent such a strong selection pressure, that pests rapidly evolve resistance. Organic agriculture practices provide a more sustainable way of producing healthy food; however, the lower yields often associated with those practices, making the resultant healthy food more expensive, open the criticism that such practices will not be able to feed human populations. Evolutionary plant breeding offers the possibility of using the evolutionary potential of crops to our advantage by producing a continuous flow of varieties better adapted to organic systems, to climate change and to the ever changing spectrum of pests, without depending on chemical control.

  13. Sustainable Urban Agriculture in Ghana: What Governance System Works?

    Directory of Open Access Journals (Sweden)

    Eileen Bogweh Nchanji

    2017-11-01

    Full Text Available Urban farming takes advantage of its proximity to market, transport and other urban infrastructure to provide food for the city and sustain the livelihoods of urban and peri-urban dwellers. It is an agricultural activity which employs more than 50% of the local urban population with positive and negative impacts on local and national development. Urban agriculture is an informal activity not supported by law but in practice is regulated to a certain extent by state institutions, traditional rulers, farmers and national and international non-governmental organisations. Tamale’s rapid population growth, exacerbated by the unplanned development system and institutional conflicts, are factors contributing to the present bottlenecks in the urban agricultural system. In this paper, these bottlenecks are conceptualised as problems of governance. These issues will be illustrated using ethnographic data from land sales, crop-livestock competition, waste-water irrigation, and markets. I will explain how conflicts which arise from these different situations are resolved through the interactions of various governance systems. Informal governance arrangements are widespread, but neither they nor formal systems are always successful in resolving governance issues. A participatory governance does not seem possible due to actors’ divergent interests. A governance solution for this sector is not yet apparent, contributing to food and nutritional insecurity.

    2018-03-01

    Full Text Available Agriculture in China started about 8000 BCE with cultivation of millet and rice. Thus, China's modern agriculture is rooted in a long evolutionary history of agricultural practices. China's population of 211 million in 1700 increased to 295 million in 1800, 400 million in 1900, 1266 million in 2000, and is 1409 million in 2017. Thus, China has to feed 18.5% of the world population on merely 7% of the world's arable land and with even scarcer water resources. Yet, between 1950 and 2017, the grain production in China increased at a faster rate than that of the population. Total grain production (million ton or Tg was 113 in 1949, 305 in 1970, 462 in 2000, and 603 in 2015. The high agricultural productivity is attributed to high consumption of fertilizers (58.8 Tg in 2015, pesticides (1.81 Tg in 2014, and irrigation (65.7 Mha in 2014. However, the high production is also associated with the severe problems of soil degradation (erosion, water contamination and air pollution. It is estimated that ~40% of China's arable land is degraded to some degree. Thus, there is a strong need for a paradigm shift of sustaining high productivity while restoring quality of natural resources of soil, water and air. In this context, conversion to a system-based conservation agriculture (CA may be an important strategy of sustainable intensification of agro-ecosystems for advancing and sustaining high production while restoring soil health, purifying water and air and improving the environment. The CA has been practiced in China since 1990s and was adopted on ~8.0 Mha in 2015. The available literature shows that conversion to CA increases soil organic C (SOC concentration and stocks mostly in the surface layer while also producing an equivalent agronomic yield. Therefore, a widespread adoption of CA in China would necessitate a deeper understanding of its ecological underpinnings. To be effective, site-specific CA practices must reduce risks of soil erosion under

    The global and regional potentials of Earth Observation (EO) to contribute to food security and sustainable agriculture in the 2050-timeframe were analysed in the ESA study EO4Food, whose outcome will be presented (www.EO4Food.org). Emphasis was put on the global societal, economic, environmental and technological megatrends that will create demand for food and shape the future societies. They will also constitute the background for developments in EO for food security and sustainable agriculture. The capabilities of EO in this respect were critically reviewed with three perspectives 1) the role of EO science for society, 2) observables from space and 3) development of future science missions.It was concluded that EO can be pivotal for the further development of food security and sustainable agriculture. EO allows to support the whole economic and societal value chain from farmers through food industry to insurance and financial industry in satisfying demands and at the same time to support society in governing sustainable agriculture through verifyable rules and regulations. It has the potential to become the global source of environmental information that is assimilated into sophisticated environmental management models and is used to make agriculture sustainable.

    Full Text Available Rapid urbanization in developing countries involves unplanned migration, unemployment and poverty. The steady shrinking of rural areas and the use of agricultural land for other purposes are progressively increasing the pressure on natural resources. This development on the one hand increases the risk to food security, and on the other triggers climate change. The rural population who migrate to the cities or who are absorbed into urban areas continue their agricultural activities in the urban in order to provide themselves with an income or to maintain their food security. In the big cities of the developed world, contact with nature is kept by means of hobby gardens, recreational areas and urban and suburban plant and animal farming, and creative ideas such as roof gardens can be found. This development, known as urban agriculture, is practiced by 800 million people in the world. Urban agriculture has many economic, social and environmental benefits, but it may also have risks and adverse effects. In this study, the developments in this area in Turkey and the world are presented, and all aspects of its effects and outcomes are discussed.

Intensive agriculture practiced without adherence to the scientific principles and ecological aspects has led to loss of soil health, and depletion of freshwater resources and agrobiodiversity. With progressive diversion of arable land for non-agricultural purposes, the challenge of feeding the growing population without, at the same time, annexing more forestland and depleting the rest of life is indeed daunting. Further, even with food availability through production/procurement, millions of marginal farming, fishing and landless rural families have very low or no access to food due to lack of income-generating livelihoods. Approximately 200 million rural women, children and men in India alone fall in this category. Under these circumstances, the evergreen revolution (pro-nature, pro-poor, pro-women and pro-employment/livelihood oriented ecoagriculture) under varied terms are proposed for achieving productivity in perpetuity. In the proposed 'biovillage paradigm', eco-friendly agriculture is promoted along with on- and non-farm eco-enterprises based on sustainable management of natural resources. Concurrently, the modern ICT-based village knowledge centres provide time- and locale-specific, demand-driven information needed for evergreen revolution and ecotechnologies. With a system of 'farm and marine production by masses', the twin goals of ecoagriculture and eco-livelihoods are addressed. The principles, strategies and models of these are briefly discussed in this paper.

    Ever increasing demands of food are met through increased production by vertical or horizontal expansion. Vertical expansion needs increased inputs (fertilizer, chemicals, etc.) supply, leaving many negative effects on environment. Horizontal expansion limits the choice for future generations. Apart from agricultural activities, agro-based industries produce large amounts of waste material. Farm waste, along with industrial waste, used as fertilizer after necessary preparation would reduce the cost of production, increase production and clean the environment. Safe and proper disposal of saline water could reduce the risk of further salinization. Alternative methods of irrigation would solve the problem of waster logging. (author)

  1. Technological Approaches to Sustainable Agriculture at a Crossroads: An Agroecological Perspective

    Directory of Open Access Journals (Sweden)

    Miguel A. Altieri

    2017-02-01

    Full Text Available Most efforts to improve agricultural production remain focused on practices driven by an intensification agenda and not by an agroecological one. Agroecology transcends the reformist notion of organic agriculture and sustainable intensification proponents who contend that changes can be achieved within the dominant agroindustrial system with minor adjustments or “greening” of the current neoliberal agricultural model. In the technological realm, merely modifying practices to reduce input use is a step in the right direction but does not necessarily lead to the redesign of a more self sufficient and autonomous farming system. A true agroecological technological conversion calls into question monoculture and the dependency on external inputs. Traditional farming systems provide models that promote biodiversity, thrive without agrochemicals, and sustain year-round yields. Conversion of conventional agriculture also requires major social and political changes which are beyond the scope of this paper.

    Full Text Available Agriculture, a key component of the structure of economic branches, should be addressed directly related to the maintenance of natural resources and their exploitation in a controlled way or the enhancement of their own, without resorting to inconsistent stimulus elements that can in time generate dysfunctions in products and the environment. Looking at things from this perspective, there is a need for a sustainable agriculture approach, given its social, ecological and economic representativeness, with active and continuous character.

    Two scientific communities with broad interest in sustainable agriculture independently focus on multifunctional agriculture or ecosystem services. These communities have limited interaction and exchange, and each group faces research challenges according to independently operating paradigms. This paper presents a comparative review of published research in multifunctional agriculture and ecosystem services. The motivation for this work is to improve communication, integrate experimental approaches, and propose areas of consensus and dialog for the two communities. This extensive analysis of publication trends, ideologies, and approaches enables formulation of four main conclusions. First, the two communities are closely related through their use of the term "function." However, multifunctional agriculture considers functions as agricultural activity outputs and prefers farm-centred approaches, whereas ecosystem services considers ecosystem functions in the provision of services and prefers service-centred approaches. Second, research approaches to common questions in these two communities share some similarities, and there would be great value in integrating these approaches. Third, the two communities have potential for dialog regarding the bundle of ecosystem services and the spectrum of multifunctional agriculture, or regarding land sharing and land sparing. Fourth, we propose an integrated conceptual framework that distinguishes six groups of ecosystem services and disservices in the agricultural landscape, and combines the concepts of multifunctional agriculture and ecosystem services. This integrated framework improves applications of multifunctional agriculture and ecosystem services for operational use. Future research should examine if the framework can be readily adapted for modelling specific problems in agricultural management. Copyright © 2014 Elsevier Ltd. All rights reserved.

  6. The Role of Biotechnology in Sustainable Agriculture: Views and Perceptions among Key Actors in the Swedish Food Supply Chain

    Directory of Open Access Journals (Sweden)

    Karin Edvardsson Björnberg

    2015-06-01

    Full Text Available Researchers have put forward agricultural biotechnology as one possible tool for increasing food production and making agriculture more sustainable. In this paper, it is investigated how key actors in the Swedish food supply chain perceive the concept of agricultural sustainability and the role of biotechnology in creating more sustainable agricultural production systems. Based on policy documents and semi-structured interviews with representatives of five organizations active in producing, processing and retailing food in Sweden, an attempt is made to answer the following three questions: How do key actors in the Swedish food supply chain define and operationalize the concept of agricultural sustainability? Who/what influences these organizations’ sustainability policies and their respective positions on agricultural biotechnology? What are the organizations’ views and perceptions of biotechnology and its possible role in creating agricultural sustainability? Based on collected data, it is concluded that, although there is a shared view of the core constituents of agricultural sustainability among the organizations, there is less explicit consensus on how the concept should be put into practice or what role biotechnology can play in furthering agricultural sustainability.

    An outline is given of the social dilemmas associated with agriculture and horticulture in the Netherlands. Ongoing innovation and accelerated sustainable development are essential to resolve these dilemmas. Given the importance of the Dutch agriculture and horticulture sector, there is every reason for the central government to play its part and help remove the obstacles to the continuing sustainable development of the sector. The Council recommends that the central government continues developing the Council's vision for agriculture and horticulture with the parties concerned, allows scope for the development of different agricultural business models, applies knowledge and innovation as drivers of continuing sustainable development, amends laws and regulations as necessary, and facilitates a permanent dialogue between the sector and society. The advisory report also sets out the Council's vision concerning the political and public debate on agriculture and horticulture. This debate is most clearly characterised by major and seemingly insurmountable differences of opinion. The Council hopes that its report will induce a shift in thinking about Dutch agriculture among politicians and society at large, so that the transitions considered necessary by the Council can be implemented more rapidly.

    Biogas production and use are generally regarded as a sustainable practice that can guarantee high greenhouse gas (GHG) savings. However, the actual carbon footprint of biogas is strongly influenced by several factors. The aim of this study is to analyse the environmental performance of different biogas to electricity scenarios. Two criticalities are identified as important: the choice of feedstock and the operational practice concerning the digestate. Maize, manure and co-digestion of them are the different feedstocks chosen. Maize has higher yields, but its cultivation has to be accounted for, which consists of 28–42% of the GHG emissions of the whole process of producing electricity. Manure is considered a residue and as a result benefits from no production stage, but also from avoided emissions from the normal agricultural practice of storing it in the farm and spreading it as fertiliser, but has lower methane yields. Co-digestion combines the benefits and disadvantages of the two different feedstocks. Digestate storage in open or closed tanks and further use as fertiliser is analysed. The environmental impact analysis shows that a substantial reduction of GHG emissions can be achieved with closed digestate storage. The GHG emissions savings vary from about 3% in the maize pathways with open storage up to 330% in the manure pathway with closed storage. The biogas pathways, though, have worse environmental performances in all other environmental impacts considered but ozone depletion potential when compared to the European electricity average mix. -- Highlights: ► Biogas sustainability depends on the feedstock and the digestate management. ► Closed storage is strongly recommended. ► Taking into consideration credits is recommended. ► The biogas pathways GHG emissions can be lower than the ones of the reference system. ► Biogas pathways have higher impact in eutrophication, ecotoxicity and PM potentials

  14. Sustainability and Competitiveness of Romanian Farms through Organic Agriculture

    Directory of Open Access Journals (Sweden)

    Mirela Ionela Aceleanu

    2016-03-01

    Full Text Available Currently, the development of any sector involves respecting the principles of sustainability, which means economic, social and environmental development. Moreover, organic farming is a very important field for ensuring sustainable development. Romania has great potential for the development of organic agriculture, especially due to the large number of available farmland and reduced use of fertilizers and other chemicals. However, the development of organic farming in Romania is in an early stage, due to the numerous problems that Romanian agriculture is still facing. Concern for the environment should be reflected at the level of production processes and consumption. As market demand influences and stimulates production, we can ask the question to what extent stimulating the consumption of organic products through green marketing can boost organic agriculture development and competitiveness of Romanian farms. Using several methods of research, such as analysis, synthesis, comparison, statistical methods and by calling on studies, reports and data series on organic farming in the EU and Romania, this paper highlights Romania's position in terms of the level of development of organic agriculture and recommends several ways to improve the outcomes obtained by Romania in the field. Moreover, based on regression equations, the trend of convergence of Romanian organic agriculture development in relation to the EU countries is analysed. The paper demonstrates that one of the measures that can be taken by Romanian farms is green marketing strategy development that can stimulate both consumption and production of organic products. Therefore, with increasing interest in the development of organic agriculture in Romania, green marketing can play an increasingly important role in promoting the benefits of consuming organic products, thus contributing to business development of organic products as well as to the development of Romanian agriculture

    Full Text Available The frequency and intensity of drought, extreme events and high wind velocities in South Africa are expected to increase in the next century as a result of the changing climate. The National Water Resource Strategy 2 (NWRS2 has set out the general and strategic directions for water resources management in the country for the next 20 years. However, the strategy does not draw a framework tailored specifically for agricultural use, with specific measures and goals. Therefore, to reach sustainability of water in agriculture, four major strategic goals are suggested, on which research institutions can focus and promote through good governance. The strategy emphasises: (1 crop research to find new drought-and heat- tolerant and resistant breeds and varieties; (2 intensified research in agricultural practices; (3 increasing the efficiency of water use within agriculture; and (4 integrating all these strategic goals within a sustainable research framework. Finally, the research calls for rapid action and implementation.

  18. Agricultural sustainability in the semi-arid Near East

    2007-05-01

    Full Text Available Agriculture began in the eastern Mediterranean Levantine Corridor about 11000 years ago toward the end of the Younger Dryas when aridity had diminished wild food resources. During the subsequent Climatic Optimum, agricultural villages spread rapidly but subsequent climatic changes on centennial to millennial scales resulted in striking oscillations in settlement, especially in marginal areas. Natural climate change thus alternately enhanced and diminished the agricultural potential of the land. Growing populations and more intensive land us, both for agriculture and livestock, have led to changes in the structure of vegetation, hydrology, and land quality. Over the millennia, political and economic interventions, warfare and incursions by nomadic herding tribes all impacted sustainability of agriculture and the ability of the land to supports its populations. In much of the region today, agricultural land use is not sustainable given existing technology and national priorities. The Near Eastern case is instructive because of the quality of information, the length of the record, and the pace of modern change.

  20. Making rainfed agriculture sustainable through environmental friendly technologies in Pakistan: A review

    Directory of Open Access Journals (Sweden)

    Mirza B. Baig

    2013-09-01

    Full Text Available Pakistan is an agricultural country spreading over an area of about 79. 6 million hectares (Mha with an arid and semi arid climate. Of 79. 6 Mha, about 23 Mha is suitable for crop production and nearly 25 percent of the total cultivated area is designated for rainfed agriculture. Unfortunately, rain-fed agriculture is constrained with multifarious problems such as moisture stress, soil erosion and crusting, nutrient deficiency, depletion and poor nutrient use efficiency, and weed infestation limiting the yield potential of these lands. In addition, deforestation and poor crop husbandry techniques are commonly noticed features. To meet the food requirements, farmers bring all the available pieces of lands under plough including steep slopes. Farming on steep slopes if not managed on scientific lines, results in severe erosion. The problems faced by the farmers are due to the unsustainable practices they adopt to practice dryland agriculture, limiting the productive potential of these important ecosystems. However, their potential can be improved by adopting suitable rainwater harvesting techniques; employing scientific soil and water conservation methods and using sustainable agricultural practices. This paper highlights some important issues associated with the rainfed agriculture of Pakistan. Working strategies for realizing optimum and sustainable yields have been outlined while conserving both land and water resources.

  6. Sustainable commercialization of new crops for the agricultural bioeconomy

    N.R. Jordan

    2016-01-01

    Full Text Available Abstract Diversification of agroecological systems to enhance agrobiodiversity is likely to be critical to advancing environmental, economic, and social sustainability of agriculture. Temperate-zone agroecological systems that are currently organized for production of summer-annual crops can be diversified by integration of fallow-season and perennial crops. Integration of such crops can improve sustainability of these agroecological systems, with minimal interference with current agricultural production. Importantly, these crops can provide feedstocks for a wide range of new bio-products that are forming a new agricultural bioeconomy, potentially providing greatly increased economic incentives for diversification. However, while there are many fallow-season and perennial crops that might be used in such a “bioeconomic” strategy for diversification, most are not yet well adapted and highly-marketable. Efforts are underway to enhance adaptation and marketability of many such crops. Critically, these efforts require a strategic approach that addresses the inherent complexity of these projects. We outline a suitable approach, which we term “sustainable commercialization”: a coordinated innovation process that integrates a new crop into the agriculture of a region, while intentionally addressing economic, environmental and social sustainability challenges via multi-stakeholder governance. This approach centers on a concerted effort to coordinate and govern innovation in three critical areas: germplasm development, multifunctional agroecosystem design and management, and development of end uses, supply chains, and markets. To exemplify the approach, we describe an ongoing effort to commercialize a new fallow-season crop, field pennycress (Thlaspi arvense L..

    Harris, Paul; Takahashi, Taro; Lee, Michael

    2017-04-01

    Agriculture at the global-scale is at a critical juncture where competing requirements for maximal production and minimal pollution have led to the concept of sustainable intensification. All farming systems (arable, grasslands, etc.) are part of this debate, where each have particular associated environmental risks such as water and air pollution, greenhouse gas emissions and soil degradation, as well as issues affecting production efficiency, product quality and consumer acceptability, reflected in the development of agricultural sustainability policies. These challenges necessitate multidisciplinary solutions that can only be properly researched, implemented and tested in real-world production systems which are suited to their geographical and climatic production practice. In this respect, various high-profile agricultural data collection experiments have been set up, such as the North Wyke Farm Platform (http://www.rothamsted.ac.uk/farmplatform) to research agricultural productivity and ecosystem responses to different management practices. In this farm-scale grasslands experiment, data on hydrology, emissions, nutrient cycling, biodiversity, productivity and livestock welfare/health are collected, that in turn, are converted to trade-off metrics with respect to: (i) economic profits, (ii) societal benefits and (iii) environmental concerns, under the umbrella of sustainable intensification. Similar agriculture research platforms have similar objectives, where data collections are ultimately synthesised into trade-off metrics. Trade-offs metrics can then be usefully visualized via the usual sustainable triangle, with a new triangle for each key time period (e.g. baseline versus post-baseline). This enables a visual assessment of change in sustainability harmony or discord, according to the remit of the given research experiment. In this paper, we discuss different approaches to calculation of the sustainability trade-off metrics that are required from the farm

    2015-04-01

    Full Text Available To improve decision-making, sustainability-based approaches to assessment of options and undertakings demand that we move beyond narrowly defined considerations to address the full suite of requirements for progress towards sustainability. This paper reports on a sustainability assessment exercise that originally focused on burning agricultural residues, primarily peanut shells, for cooking applications in Senegal. The scope of assessment had to be expanded to address the agricultural and energy systems of Senegal, when closer examination revealed a complex set of energy and agricultural system interactions that could undermine the anticipated positive effects of initiatives centred primarily on peanut residue cookstoves. The case highlights the need to be open to expanding the scope of assessment to address underlying and/or unexpected issues that cannot be addressed appropriately at the project scale. In particular, the case illustrates how the assessment of an energy system may serve as an entry point into a deeper exploration of the context in which the energy system is embedded. The analysis also illustrates a situation in which different paths that may be followed, each with its own degree of uncertainty, path dependence, feasibility, fairness, cultural sensitivity, trade-off acceptability and possibilities for public judgement of overall desirability.

    Sustainable intensification is an emerging model for agriculture designed to reconcile accelerating global demand for agricultural products with long-term environmental stewardship. Defined here as increasing agricultural production while maintaining or improving environmental quality, sustainable intensification hinges upon decision-making by agricultural producers, consumers, and policy-makers. The Long-Term Agroecosystem Research (LTAR) network was established to inform these decisions. Here we introduce the LTAR Common Experiment, through which scientists and partnering producers in US croplands, rangelands, and pasturelands are conducting 21 independent but coordinated experiments. Each local effort compares the outcomes of a predominant, conventional production system in the region (‘business as usual’) with a system hypothesized to advance sustainable intensification (‘aspirational’). Following the logic of a conceptual model of interactions between agriculture, economics, society, and the environment, we identified commonalities among the 21 experiments in terms of (a) concerns about business-as-usual production, (b) ‘aspirational outcomes’ motivating research into alternatives, (c) strategies for achieving the outcomes, (d) practices that support the strategies, and (e) relationships between practice outreach and adoption. Network-wide, concerns about business as usual include the costs of inputs, opportunities lost to uniform management approaches, and vulnerability to accelerating environmental changes. Motivated by environmental, economic, and societal outcomes, scientists and partnering producers are investigating 15 practices in aspirational treatments to sustainably intensify agriculture, from crop diversification to ecological restoration. Collectively, the aspirational treatments reveal four general strategies for sustainable intensification: (1) reducing reliance on inputs through ecological intensification, (2) diversifying management

    Sustainability standards and certification serve to differentiate and provide market recognition to goods produced in accordance with social and environmental good practices, typically including practices to protect biodiversity. Such standards have seen rapid growth, including in tropical agricultural commodities such as cocoa, coffee, palm oil, soybeans, and tea. Given the role of sustainability standards in influencing land use in hotspots of biodiversity, deforestation, and agricultural intensification, much could be gained from efforts to evaluate and increase the conservation payoff of these schemes. To this end, we devised a systematic approach for monitoring and evaluating the conservation impacts of agricultural sustainability standards and for using the resulting evidence to improve the effectiveness of such standards over time. The approach is oriented around a set of hypotheses and corresponding research questions about how sustainability standards are predicted to deliver conservation benefits. These questions are addressed through data from multiple sources, including basic common information from certification audits; field monitoring of environmental outcomes at a sample of certified sites; and rigorous impact assessment research based on experimental or quasi-experimental methods. Integration of these sources can generate time-series data that are comparable across sites and regions and provide detailed portraits of the effects of sustainability standards. To implement this approach, we propose new collaborations between the conservation research community and the sustainability standards community to develop common indicators and monitoring protocols, foster data sharing and synthesis, and link research and practice more effectively. As the role of sustainability standards in tropical land-use governance continues to evolve, robust evidence on the factors contributing to effectiveness can help to ensure that such standards are designed and

  17. Sustainable Uses of FGD Gypsum in Agricultural Systems: Introduction.

    2014-01-01

    Interest in using gypsum as a management tool to improve crop yields and soil and water quality has recently increased. Abundant supply and availability of flue gas desulfurization (FGD) gypsum, a by-product of scrubbing sulfur from combustion gases at coal-fired power plants, in major agricultural producing regions within the last two decades has attributed to this interest. Currently, published data on the long-term sustainability of FGD gypsum use in agricultural systems is limited. This has led to organization of the American Society of Agronomy's Community "By-product Gypsum Uses in Agriculture" and a special collection of nine technical research articles on various issues related to FGD gypsum uses in agricultural systems. A brief review of FGD gypsum, rationale for the special collection, overviews of articles, knowledge gaps, and future research directions are presented in this introductory paper. The nine articles are focused in three general areas: (i) mercury and other trace element impacts, (ii) water quality impacts, and (iii) agronomic responses and soil physical changes. While this is not an exhaustive review of the topic, results indicate that FGD gypsum use in sustainable agricultural production systems is promising. The environmental impacts of FGD gypsum are mostly positive, with only a few negative results observed, even when applied at rates representing cumulative 80-year applications. Thus, FGD gypsum, if properly managed, seems to represent an important potential input into agricultural systems.

    Full Text Available Currently, many have been concerned with the oil palm cultivation since it may also put land resources in danger and bring about environmental damage. Poor practices in managing agricultural land very often occur due to the inadequate knowledge of soil conservation. Application of soil and water conservation is to maintain the productivity of the land and to prevent further damage by considering land capability classes. This research was aimed at obtaining soil and water conservation techniques which are the most appropriate and optimal for oil palm cultivation areas based on land capability classes which can support sustainable oil palm cultivation. Several soil conservation techniques had been treated to each different class III, IV, and VI of the studied area. These treatment had been performed by a standard plot erosion. The results showed for the land capability class III, Cover plants + Manure was able to control runoff, erosion and reduce leaching of N (LSD P≤0,05, in which soil conservation produced the lowest erosion (3,73t/ha, and N leaching (0,25%. On land capability class IV, Sediment Trap + cover plants+ manure was able to control runoff, erosion and reduce organic C and P leaching (LSD P≤0,05, in which soil conservation produced the lowest runoff (127,77 m3/ha, erosion (12,38t/ha, organic C leaching (1,14 %, and P leaching (1,28 ppm. On land capability class VI, there isn’t significant effect of soil conservation, but Bench Terrace + cover plants +manure has the lowest runoff, erosion and soil nutrient leaching.

    Full Text Available In Western economies, several agriculture models coexist. For instance, intensive agriculture organization, which has increased yields while causing major pollution and resource depletion, competes with alternative models, which tackle these sustainability issues and lead to lower yields. An agronomical typology of current agriculture models in Western societies is proposed that describes multiple sustainability issues through an agroecological perspective. However, in order to choose between these agroecological pathways, we must understand their social structure and the principles underlying them. Thus, our purpose is to characterize the institutional aspects of the alternative models using socioeconomic convention theory. We conducted a series of workshops with specialists in the natural sciences (agronomy, landscape ecology, and entomology and social sciences (economics and sociology to describe sustainable agriculture models. This characterization revealed the values underlying six different sustainable agriculture models, their forms of organization, and the institutions governing them. We discuss the implications of the coexistence of these six models in light of sustainable transition issues. From this coexistence perspective, transition (i refers to an intertwined process of legitimation and disqualification, and (ii means seeing pathways as the multiplicity and degree of interconnection between models. Therefore, we (i identified the elements in each model that legitimize its mode of organization, and (ii disqualified the elements that are incompatible with the principles underlying the model's practices. Moreover, we emphasize that multiple transition pathways are possible based on complex, complementary combinations of different models. This revealed the intricate processes of competition and complementarity involving these models. Finally, our study on the coexistence, interdependence, and coevolution of multiple agriculture models

    Drought is considered as one of the major natural hazards with a significant impact on agriculture, environment, society and economy. Droughts affect sustainability of agriculture and may result in environmental degradation of a region, which is one of the factors contributing to the vulnerability of agriculture. This paper addresses agrometeorological or agricultural drought within the risk management framework. Risk management consists of risk assessment, as well as a feedback on the adopted risk reduction measures. And risk assessment comprises three distinct steps, namely risk identification, risk estimation and risk evaluation. This paper deals with risk identification of agricultural drought, which involves drought quantification and monitoring, as well as statistical inference. For the quantitative assessment of agricultural drought, as well as the computation of spatiotemporal features, one of the most reliable and widely used indices is applied, namely the vegetation health index (VHI). The computation of VHI is based on satellite data of temperature and the normalized difference vegetation index (NDVI). The spatiotemporal features of drought, which are extracted from VHI, are areal extent, onset and end time, duration and severity. In this paper, a 20-year (1981-2001) time series of the National Oceanic and Atmospheric Administration/advanced very high resolution radiometer (NOAA/AVHRR) satellite data is used, where monthly images of VHI are extracted. Application is implemented in Thessaly, which is the major agricultural drought-prone region of Greece, characterized by vulnerable agriculture. The results show that agricultural drought appears every year during the warm season in the region. The severity of drought is increasing from mild to extreme throughout the warm season, with peaks appearing in the summer. Similarly, the areal extent of drought is also increasing during the warm season, whereas the number of extreme drought pixels is much less than

  4. Sustainability of natural attenuation of nitrate in agricultural aquifers

    2010-01-01

    Increased concentrations of nitrate in groundwater in agricultural areas, coinciding with increased use of chemical and organic fertilizers, have raised concern because of risks to environmental and human health. At some sites, these problems are mitigated by natural attenuation of nitrate as a result of microbially mediated reactions. Results from U.S. Geological Survey (USGS) research under the National Water-Quality Assessment (NAWQA) program show that reactions of dissolved nitrate with solid aquifer minerals and organic carbon help lower nitrate concentrations in groundwater beneath agricultural fields. However, increased fluxes of nitrate cause ongoing depletion of the finite pool of solid reactants. Consumption of the solid reactants diminishes the capacity of the aquifer to remove nitrate, calling into question the long-term sustainability of these natural attenuation processes.

    A conservative projection shows the world's population growing by 32% (to 9.5 billion) by 2050 and 53% (to 11 billion) by 2100 compared with its current level of 7.2 billion. Because most arable land worldwide is already in use, and water and energy also are limiting, increased production of food will require a substantial increase in efficiency. In this article, we highlight the importance of animals to achieving food security in terms of their valuable contributions to agricultural sustainability, especially in developing countries, and the high nutritional value of animal products in the diet. © 2015 American Society for Nutrition.

  7. Knowledge, conservation and sustainable use of soil: agricultural chemistry aspects

    Full Text Available Soil is an environmental resource and plays ecological, social and economic functions which are fundamental for the life. To guarantee its availability to future generations, soil resource needs sustainable management. The CEC Thematic Strategy for Soil Protection identifies a series of soil degradation processes or threats, which must be identified and combated. These include erosion, decline in organic matter, local and diffuse contamination, sealing, compaction, decline in biodiversity, salinisation, floods and landslides. With respect to management of contamination with potentially toxic elements, an approach based on the identification and quantification of the various forms or, at least, the main pools, in which contaminants occur in soil, is envisaged. The residence time of an element in soil depends, indeed, by the mobility of its predominant forms. Speciation studies provide information on the mobility and biological availability of contaminants, and seek to assess not simply the contamination level, but rather the risk/toxicity of a polluted soil and to predict its reduction after application of remediation techniques. Soil degradation is often associated with a decrease in the organic matter content, mainly caused by soil use change and global warming. Improving the accumulation of organic matter in soil or contrasting its reduction has positive effects on soil and water quality, crop yields, biodiversity and climate leading to a reduction of green-house gas emissions from soil to the atmosphere. In order to obtain a real accumulation of organic matter in soil, it is not sufficient to temporarily increase its total content, but it is necessary to favour the main processes which govern organic matter stabilization. This requires an approach at both molecular and multidisciplinary level.

    Full Text Available Increasing global demand for oil seeds and cereals during the past 50 years has caused an expansion in the cultivated areas and resulted in major soil management and crop production changes throughout Bolivia, Paraguay, Uruguay, Argentina and southern Brazil. Unprecedented adoption of no-tillage as well as improved soil fertility and plant genetics have increased yields, but the use of purchased inputs, monocropping i.e., continuous soybean (Glycine max (L. Merr., and marginal land cultivation have also increased. These changes have significantly altered the global food and feed supply role of these countries, but they have also resulted in various levels of soil degradation through wind and water erosion, soil compaction, soil organic matter (SOM depletion, and nutrient losses. Sustainability is dependent upon local interactions between soil, climate, landscape characteristics, and production systems. This review examines the region’s current soil and crop conditions and summarizes several research studies designed to reduce or prevent soil degradation. Although the region has both environmental and soil resources that can sustain current agricultural production levels, increasing population, greater urbanization, and more available income will continue to increase the pressure on South American croplands. A better understanding of regional soil differences and quantifying potential consequences of current production practices on various soil resources is needed to ensure that scientific, educational, and regulatory programs result in land management recommendations that support intensification of agriculture without additional soil degradation or other unintended environmental consequences.

  10. Ecologically sustainable chemical recommendations for agricultural pest control?

    Thomson, Linda J; Hoffmann, Ary A

    2007-12-01

    Effective pest control remains an essential part of food production, and it is provided both by chemicals and by natural enemies within agricultural ecosystems. These methods of control are often in conflict because of the negative impact of chemicals on natural enemies. There are already well-established approaches such as those provided by the International Organization for Biological and Integrated Control-Pesticides and Beneficial Organisms for testing, collecting, and publishing information on responses of natural enemies to chemicals based on laboratory responses of specific organisms; however, these tests do not assess the cumulative impact of chemical inputs across an entire season or consider impacts on the complex communities of natural enemies that can provide effective pest control on a farm. Here, we explore the potential of different approaches for assessing the impact of chemicals on agricultural ecosystems and we propose a simple metric for sustainable chemical use on farms that minimizes overall impact on beneficial groups. We suggest ways in which the effectiveness of metrics can be extended to include persistence and habitat features. Such metrics can assist farmers in developing targets for sustainable chemical use as demonstrated in the viticultural industry.

    Full Text Available This article explores the impact of climate change and variability on agricultural productivity in the communal area of Bikita. The article further examines the adaptation and mitigation strategies devised by farmers to deal with the vagaries of climate change and variability. The sustainability of these is also interrogated in this article. This study juxtaposed qualitative and quantitative methodologies albeit with more bias on the former. A total of 40 farmers were sampled for unstructured interviews and focus group discussions. This article argues that the adverse impacts of climate change and variability are felt heavily by the poor communal farmers who are directly dependent on agriculture for livelihood. From the study, some of the widely reported signs of climate variability in Bikita included late and unpredictable rains, high temperatures (heat waves, successive drought, shortening rainfall seasons and seasonal changes in the timing of rainfall. The paper argues that climate change has compounded the vulnerability of peasant farmers in the drought - prone district of Bikita plunging them into food insecurity and abject poverty. It emerged in the study that some of effects of climate variability felt by communal farmers in Bikita included failure of crops, death of livestock and low crop yields, all of which have led to declining agricultural productivity. Findings in this study however established that communal farmers have not been passive victims of the vagaries of climate change and variability. They have rationally responded to it through various adaptation and mitigation strategies both individually and collectively.

    Rain-fed agricultural production supported by exogenous inputs is not sustainable because a continuous influx of expensive inputs (fertilizer, chemicals, fossil fuel, labor, tillage, and other) is required. Alternatives to traditional management allow natural occurring dynamic soil processes to provide the necessary microbial activity that supports nutrient cycling in balance with nature. Research designed to investigate the potential for integrated systems to replace expensive inputs has shown that healthy soils rich in soil organic matter (SOM) are the foundation upon which microbial nutrient cycling can reduce and eventually replace expensive fertilizer. No-till seed placement technology effectively replaces multiple-pass cultivation conserving stored soil water in semi-arid farming systems. In multi-crop rotations, cool- and warm-season crops are grown in sequence to meet goals of the integrated farming and ranching system, and each crop in the rotation complements the subsequent crop by supplying a continuous flow of essential SOM for soil nutrient cycling. Grazing animals serve an essential role in the system's sustainability as non-mechanized animal harvesters that reduce fossil fuel consumption and labor, and animal waste contributes soil nutrients to the system. Integrated systems' complementarity has contributed to greater soil nutrient cycling and crop yields, fertilizer reduction or elimination, greater yearling steer grazing net return, reduced cow wintering costs grazing crop residues, increased wildlife sightings, and reduced environmental footprint. Therefore, integrating crop and animal systems can reverse soil quality decline and adopting non-traditional procedures has resulted in a wider array of opportunities for sustainable agriculture and profitability.

    2012-10-01

    Agricultural residues have significant potential as a near term source of cellulosic biomass for bioenergy production, but sustainable removal of agricultural residues requires consideration of the critical roles that residues play in the agronomic system. Previous work has developed an integrated model to evaluate sustainable agricultural residue removal potential considering soil erosion, soil organic carbon, greenhouse gas emission, and long-term yield impacts of residue removal practices. The integrated model couples the environmental process models WEPS, RUSLE2, SCI, and DAYCENT. This study uses the integrated model to investigate the impact of interval removal practices in Boone County, Iowa, US. Residue removal of 4.5 Mg/ha was performed annually, bi-annually, and tri-annually and were compared to no residue removal. The study is performed at the soil type scale using a national soil survey database assuming a continuous corn rotation with reduced tillage. Results are aggregated across soil types to provide county level estimates of soil organic carbon changes and individual soil type soil organic matter content if interval residue removal were implemented. Results show interval residue removal is possible while improving soil organic matter. Implementation of interval removal practices provide greater increases in soil organic matter while still providing substantial residue for bioenergy production.

    A major problem for irrigated agricultural production is soil salinization, which can occur naturally or can be human-induced. Human-induced, or secondary salinization, is particularly a problem in arid and semi-arid regions, especially in irrigated areas. Irrigated land has more than twice the production of rainfed land, and accounts for about one third of the world's food, but nearly 20% of irrigated lands are salt-affected. Many farmers worldwide currently seasonally leach their land to reduce the soil salt content. These practices, however, create further problems such as a raised groundwater table, and salt, fertilizer, and pesticide pollution of nearby lakes and groundwater. In Uzbekistan, a combination of these management practices and a propensity to cultivate 'thirsty' crops such as cotton has also contributed to the Aral Sea shrinking nearly 90% by volume since the 1950s. Most common agricultural crops are glycophytes that have reduced yields when subjected to salt-stress. Some plants, however, are known as halophytic or 'salt-loving' plants and are capable of completing their life-cycle in higher saline soil or water environments. Halophytes may be useful for human consumption, livestock fodder, or biofuel, and may also be able to reduce or maintain salt levels in soil and water. To assess the potential for these halophytes to assist with salinity management, we are developing a model that is capable of tracking salinity under different management practices in agricultural environments. This model is interdisciplinary as it combines fields such as plant ecology, hydrology, and soil science. The US Department of Agriculture (USDA) model, Agricultural Policy/Environmental Extender (APEX), is being augmented with a salinity module that tracks salinity as separate ions across the soil-plant-water interface. The halophytes Atriplex nitens, Climacoptera lanata, and Salicornia europaea are being parameterized and added into the APEX model database. Field sites

However, the selection of optimal mine water management practices is technically challenging due to the lack of scientific tools to comprehensively evaluate management options against a set of conflicting criteria. This work has provided a solution to aid the identification of more sustainable mine water management practices. The solution includes a conceptual framework for forming a decision hierarchy; an evaluation method for assessing mine water management practices; and a sensitivity analysis in view of different preferences of stakeholders or managers. The solution is applied to a case study of the evaluation of sustainable water management practices in 16 mines located in the Bowen Basin in Queensland, Australia. The evaluation results illustrate the usefulness of the proposed solution. A sensitivity analysis is performed according to preference weights of stakeholders or managers. Some measures are provided for assessing sensitivity of strategy ranking outcomes if the weight of an indicator changes. Finally, some advice is given to improve the mine water management in some mines.

    Arbuscular mycorrhizal (AM) fungi are rich in diversity in agricultural ecosystem, playing a vital role based on their unique community structure. Host plants and environmental factors have important effects on AM fungal community structure, so do the agricultural practices which deserve to pay attention to. This paper summarized the research advances in the effects of agricultural practices such as irrigation, fertilization, crop rotation, intercropping, tillage, and pesticide application on AM fungal community structure, analyzed the related possible mechanisms, discussed the possible ways in improving AM fungal community structure in agricultural ecosystem, and put forward a set of countermeasures, i.e., improving fertilization system and related integrated techniques, increasing plant diversity in agricultural ecosystem, and inoculating AM fungi, to enhance the AM fungal diversity in agricultural ecosystem. The existing problems in current agricultural practices and further research directions were also proposed.

    The challenge of meeting the projected doubling of global demand for food by 2050 is monumental. It is further exacerbated by the limited prospects for land expansion and rapidly dwindling water resources. A promising strategy for increasing crop yields per unit land requires the expansion of irrigated agriculture and the harnessing of water sources previously considered "marginal" (saline, treated effluent, and desalinated water). Such an expansion, however, must carefully consider potential long-term risks on soil hydroecological functioning. The study provides critical analyses of use of marginal water and management approaches to map out potential risks. Long-term application of treated effluent (TE) for irrigation has shown adverse impacts on soil transport properties, and introduces certain health risks due to the persistent exposure of soil biota to anthropogenic compounds (e.g., promoting antibiotic resistance). The availability of desalinated water (DS) for irrigation expands management options and improves yields while reducing irrigation amounts and salt loading into the soil. Quantitative models are used to delineate trends associated with long-term use of TE and DS considering agricultural, hydrological, and environmental aspects. The primary challenges to the sustainability of agroecosystems lies with the hazards of saline and sodic conditions, and the unintended consequences on soil hydroecological functioning. Multidisciplinary approaches that combine new scientific knowhow with legislative, economic, and societal tools are required to ensure safe and sustainable use of water resources of different qualities. The new scientific knowhow should provide quantitative models for integrating key biophysical processes with ecological interactions at appropriate spatial and temporal scales.

    Globally, irrigated agriculture is the largest abstractor, and predominant consumer, of groundwater resources, with large groundwater-dependent agro-economies now having widely evolved especially in Asia. Such use is also causing resource depletion and degradation in more arid and drought-prone regions. In addition crop cultivation practices on irrigated land exert a major influence on groundwater recharge. The interrelationship is such that cross-sector action is required to agree more sustainable land and water management policies, and this paper presents an integrated vision of the challenges in this regard. It is recognised that 'institutional arrangements' are critical to the local implementation of management policies, although the focus here is limited to the conceptual understanding needed for formulation of an integrated policy and some practical interventions required to promote more sustainable groundwater irrigation.

    Full Text Available We performed a Water Footprint Sustainability Assessment (WFSA in the Xingu Basin of Mato Grosso (XBMT, Brazil, with the objectives of (1 tracking blue (as surface water and green water (as soil moisture regenerated by precipitation consumption in recent years (2000, 2014; and (2 evaluating agricultural intensification options for future years (2030, 2050 considering the effects of deforestation and climate change on water availability in the basin. The agricultural sector was the largest consumer of water in the basin despite there being almost no irrigation of cropland or pastures. In addition to water use by crops and pasture grass, water consumption attributed to cattle production included evaporation from roughly 9463 ha of small farm reservoirs used to provide drinking water for cattle in 2014. The WFSA showed that while blue and green water consumptive uses were within sustainable limits in 2014, deforestation, cattle confinement, and the use of irrigation to increase cropping frequency could drive water use to unsustainable levels in the future. While land management policies and practices should strive for protection of the remaining natural vegetation, increased agricultural production will require reservoir and irrigation water management to reduce the potential threat of blue water scarcity in the dry season. In addition to providing general guidance for future water allocation decisions in the basin, our study offers an interpretation of blue and green water scarcities with changes in land use and climate in a rapidly evolving agricultural frontier.

    Full Text Available Climate change and the subsequent change in agricultural conditions increase the vulnerability of agricultural water use. Wastewater reuse is a common practice around the globe and is considered as an alternative water resource in a changing agricultural environment. Due to rapid urbanization, indirect wastewater reuse, which is the type of agricultural wastewater reuse that is predominantly practiced, will increase, and this can cause issues of unplanned reuse. Therefore, water quality standards are needed for the safe and sustainable practice of indirect wastewater reuse in agriculture. In this study, irrigation water quality criteria for wastewater reuse were discussed, and the standards and guidelines of various countries and organizations were reviewed to suggest preliminary standards for indirect wastewater reuse in South Korea. The proposed standards adopted a probabilistic consideration of practicality and classified the use of irrigation water into two categories: upland and rice paddy. The standards suggest guidelines for E. coli, electric conductivity (EC, turbidity, suspended solids (SS, biochemical oxygen demand (BOD, pH, odor, and trace elements. Through proposing the standards, this study attempts to combine features of both the conservative and liberal approaches, which in turn could suggest a new and sustainable practice of agricultural wastewater reuse.

    Agricultural expansion is mostly done at the expense of forests and woodlands in the tropics. In Sub-Saharan Africa, forests are also critical as providers of wood energy for domestic consumption with a clear majority of households depending on firewood and charcoal as primary source of energy. Using Zambia as a case study, we look at the link between agricultural expansion, wood energy and the sustainability of forest resources. Zambia has been identified as having one of the highest rates of deforestation in the world, but there is large uncertainty in these estimates. The government of Zambia has identified charcoal production as one of the main of drivers of forest cover loss and is targeting this practice in their national strategy for reducing emissions from deforestation and forest degradation (REDD+). Other assessment however indicate that agricultural expansion is by far the main driver of deforestation and charcoal production is sustainable in Zambia. These competing evaluations call for a better understanding of the drivers of change. Using two national-scale vegetation surveys and remote sensing data, we compare and validate historical forest cover loss estimates to improve their accuracy. We attribute the change and their associated emissions to specific drivers of deforestation. The ecological properties of areas under change are compared to stable areas over time. Our results from national permanent plots indicate a woody encroachment process in Zambia, a potential ecological response to rising CO2 levels. We found that despite large emissions from deforestation, forests and woodlands have been acting as a carbon sink. This research addresses directly the potential feedbacks and responses to competing demands on forests coming from different sectors, including for agriculture and energy, to set the baseline on which to evaluate forest sustainability now and in the future given potentially new ecological conditions. It provides policy relevant

    The unsustainable use of the soil of the deforested area at the Amazonian border is one of the greatest threats to the rainforest, because it is the predominant cause of shifting cultivation in the region. The sustainable management of soils with low natural fertility is a major challenge for smallholder agriculture in the humid tropics. In the periphery of Brazilian Amazonia, agricultural practices that are recommended for the Brazilian savannah, such as saturating soils with soluble nutrients do not ensure the sustainability of agroecosystems. Improvements in the tilled topsoil cannot be maintained if deterioration of the porous soil structure is not prevented and nutrient losses in the root zone are not curtailed. The information gleaned from experiments affirms that in the management of humid tropical agrosystems, the processes resulting from the interaction between climatic factors and indicators of soil quality must be taken into consideration. It must be remembered that these interactions manifest themselves in ways that cannot be predicted from the paradigm established in the other region like the southeast of Brazil, which is based only on improving the chemical indicators of soil quality. The physical indicators play important role in the sustainable management of the agrosystems of the region and for these reasons must be considered. Therefore, alley cropping is a potential substitute for slash and burn agriculture in the humid tropics with both environmental and agronomic advantages, due to its ability to produce a large amount of residues on the soil surface and its effect on the increase of economic crop productivity in the long term. The article presents some promising patents on the importance of an alternative for sustainability of agriculture.

    2008-05-01

    Global agriculture faces some unique challenges and opportunities for the rest of this century. The need for food, feed and fiber will continues to grow as the world population continue to increase in the future. Agricultural ecosystems are also expected to be the source of a significant portion of renewable energy and fuels around the world, without further compromising the integrity of the natural resources base. How can agriculture continue to provide these services to meet the growing needs of world population while sustaining the integrity of agricultural ecosystems and natural resources, the very foundation it depends on? In the last century, scientific discoveries and technological innovations in agriculture resulted in significant increase in food, feed and fiber production globally, while the total amount of water, energy, fertilizers and other input used to achieve this growth remained the same or even decreased significantly in some parts of the world. Scientific and technical advances in understanding global and regional water and energy cycles, water resources management, soil and water conservation practices, weather prediction, plant breeding and biotechnology, and information and communication technologies contributed to this tremendous achievement. The projected increase in global population, urbanization, and changing lifestyles will continue the pressure on both agriculture and other managed and natural ecosystems to provide necessary goods and services for the rest of this century. To meet these challenges, we must obtain the requisite scientific and technical advances in the functioning of Earth's water, energy, carbon and biogeochemical cycles. We also need to apply the knowledge we gain and technologies we develop in assessing Earth's ecosystems' conditions, and their management and stewardship. In agricultural ecosystems, management of soil and water quality and quantity together with development of new varieties of plants based on advances

    There is no question that human must produce additional 70% food to feed the new 2.2 billion of people on the planet by 2050, but the question is where to grow the additional food. The demand for the additional food lies not only in producing the basic resources needed to sustain a healthy lifestyle, but also from a changing diet, especially in rapidly developing countries in the dryland regions around the world. It is forecast that this demand for meat will require an additional 0.2 billion tons per year by 2050, which is almost a doubling of present meat consumption. These new demands create mounting pressures on agriculture and pastoral ecosystems and the reported trajectory of warmer and drier climate in the future increases uncertainties in food security, adding further stresses to the already stressed nations in the Asian dryland belt. Different approaches are being either proposed or practiced in the region but the question is whether or not the current practices are sustainable or optimal in addressing the emerging issues. Given the complexity and interplay among the food, water and energy, what are alternatives to ensure a sustainable trajectory of regional development to meet the new food demand? This presentation reviews existing practices and proposes alternative solutions, by specifically examining the trade-offs between different ecosystem services that drylands in Asian may provide. Preliminary analysis suggested that the current trajectory of meat and milk production is likely not on a sustainable pathway.

  13. Can Precision Agriculture Increase the Profitability and Sustainability of the Production of Potatoes and Olives?

    2017-10-01

    Full Text Available For farmers, the application of Precision Agriculture (PA technology is expected to lead to an increase in profitability. For society, PA is expected to lead to increased sustainability. The objective of this paper is to determine for a number of common PA practices how much they increase profitability and sustainability. For potato production in The Netherlands, we considered variable rate application (VRA of soil herbicide, fungicide for late blight control, sidedress N, and haulm killing herbicide. For olive production in Greece, we considered spatially variable application of P and K fertilizer and lime. For each of the above scenarios, we quantified the value of outputs, the cost of inputs, and the environmental costs. This allowed us to calculate profit as well as social profit, where the latter is defined as revenues minus conventional costs minus the external costs of production. Social profit can be considered an overall measure of sustainability. Our calculations show that PA in potatoes increases profit by 21% (420 € ha−1 and social profit by 26%. In olives, VRA application of P, K, and lime leads to a strong reduction in nutrient use and although this leads to an increase in sustainability, it has only a small effect on profit and on social profit. In conclusion, PA increases sustainability in olives and both profitability and sustainability in potatoes.

  14. A Need for Education in Water Sustainability in the Agricultural Realm

    2015-12-01

    This study draws upon the definition of water sustainability from the National Water Research Institute as the continual supply of clean water for human uses and for other living beings without compromising the water welfare of future generations. Currently, the greatest consumer of water resources worldwide is irrigation. The move from small-scale, family farms towards corporately owned and market driven, mass scale operations have drastically increased corn production and large-scale factory hog farming in the American Midwest—and the water quality related costs associated with this shift are well-documented. In the heart of the corn belt, the state of Iowa has dealt with issues over the past two decades ranging from flooding of historic proportions, to yield destroying droughts. Most recently, the state's water quality is intensely scrutinized due to nutrient levels higher than almost anywhere else in the world. While the changed agricultural landscape is ultimately responsible for these environmental costs, they can be mitigated if the farmers adopt practices that support water sustainability. However, many Iowa farmers have yet to embrace these necessary practices because of a lack of proper education in this context. Thus, the purpose of this paper is to explore how water sustainability is being conceptualized within the agricultural realm, and ultimately, how the issues are being communicated and understood within various subgroups in Iowa, such as the farmers, the college students, and the general public.

    Full Text Available The soil and land resources play a vital role in sustaining the local livelihoods of rural communities in the Himalaya. Most of the arable land has already been brought under cultivation, hence the ever-increasing demand for food and fiber has left farmers with no choice but to intensify agriculture. However, producing more crops and greater quantities of food, fiber and other materials on the same parcel of land can to soil fertility and productivity decline with overall degradation of land quality. Therefore, ways and means to intensify agriculture to enhance productivity without degrading the soil and land resource base have become imperative. Agro-forestry, agro-slivi-pastoral systems, and the adoption of a variety of crop, soil and water management and conservation practices offer potential to deliver multiple benefits without sacrificing the very resource upon which the human population depends. Presented herein are findings on approaches to sustainable intensification of agriculture and land management related to soil OM management and C sequestration for multiple benefits, and, agro-forestry as a crop diversification strategy with both livelihood, and climate change adaptation/mitigation benefits. The results indicate that sustainable soil management practices could lead to significant SOC accumulations (4-8 t/ha over 6 yrs. SOC and soil C stocks tend to increase with elevation due to cooler climate and slow decomposition rates. Carbon stocks for the 3 LU types was in the order CF>AF/LH>AG, suggesting that diversified cropping practices including agro-forestry have good potential sequester C while providing livelihood opportunities and climate adaptive capacity for local farming communities. Biochar amendment increased growth of both coffee plants and radish with mixed grass/weed biochar being most effective. Biochar application also significantly decreased emission of GHGs, especially N2O.

    Full Text Available The exposed carbonate rocks aged from Sinian to Mid-Triassic Periods cover an area of 500,000 Km2 in south-west China. In karst areas with spectacular landscapes characterized by magnificent tower karst and conical karst, rare surface drainage systems and prevalent subsurface drainage systems, the environment is ecologically very fragile. The rapid increase of population, over deforested and cultivated lands, worsted the ecological system, causing a higher frequency of draught, flood and various disasters, backward economic development, low living standard of the people. In order to improve the sustainability of the agriculture the experience shows that the following operations should be adopted: (1 serious control of the population increase, emigration, extra labours and improvement of the environmental education of the local inhabitants; (2 terracing of the slopes (shi jala di as to improve the cultivated land quality, to preserve the water, soil and fertiliser and ameliorate the effective utilisation of the land; (3 development of new rural energies such as the solar energy and gas energy, and expansion of the saving-fuel stoves to reduce the load of bio-energy; (4 reforestation and bounding the hills and mountains; the ecological, economic and fuel forests model has been developed in fengcong-depression areas: the tree species with high ecological, economical and energetic characteristics, should be chosen, such as the bamboo, wild grapes, Sapium rotundifolium etc.; (5 better utilisation of the ram water and karst water resource to solve the water supply problems.

    International Nuclear Information System (INIS)

    Simon, Sonja; Wiegmann, Kirsten

    2009-01-01

    This paper presents a model for analyzing the sustainable potential of agricultural biomass for energy production. Available land and residue potentials are assessed up to 2030 for Germany, Poland, the Czech Republic and Hungary. Two scenarios are presented: a ''business as usual'' scenario is compared to a sustainability scenario. The latter implements a comprehensive sustainability strategy, taking also into account non-agricultural land use such as building activity and nature conservation. On the one hand our model quantifies the conflict of objectives between enhanced extensification in agriculture and increased area for nature conservation. On the other hand the synergies in restricting built up area and increased mobilisation of agricultural residues are assessed. Additionally the impact of reduced subsidized agricultural exports from the EU is calculated, also as an indicator for the influence of world food markets on bioenergy potentials. Our results show that the sustainable energy potential from agricultural biomass is strongly restricted for Germany and the Czech Republic compared to their energy demand. But in Poland and Hungary native agricultural biomass provides a much higher potential for energy supply, even if sustainability is comprehensively considered. However, this is strongly influenced by the amount of agricultural exports of each country. For bioenergy from agricultural cultivation to remain a sustainable option in the energy sector, its influence on the food markets must be respected more thoroughly and a comprehensive approach to sustainable development in land use is a prerequisite.

    2013-01-01

    Full Text Available In the post independence period, the most important challenge in India has been to produce enough food for the growing population. Hence, high-yielding varieties are being used with infusion of irrigation water, fertilizers, or pesticides. This combination of high-yielding production technology has helped the country develop a food surplus as well as contributing to concerns of soil health, environmental pollution, pesticide toxicity, and sustainability of agricultural production. Scientists and policy planners are, therefore, reassessing agricultural practices which relied more on biological inputs rather than heavy usage of chemical fertilizers and pesticides. Organic farming can provide quality food without adversely affecting the soil’s health and the environment; however, a concern is whether large-scale organic farming will produce enough food for India’s large population. Certified organic products including all varieties of food products including basmati rice, pulses, honey, tea, spices, coffee, oilseeds, fruits, cereals, herbal medicines, and their value-added products are produced in India. Non edible organic products include cotton, garments, cosmetics, functional food products, body care products, and similar products. The production of these organic crops and products is reviewed with regard to sustainable agriculture in northern India.

    Full Text Available Management of agricultural practices plays a vital role in reducing the use of limited water resources in arid and semi-arid regions which could result in their sustainability. In this research, the role of managing agriculture in sustaining flow of Zayandeh-rud was studied by calculation of rice water requirement (actual evapotranspiration in paddy fields of Zarrin-shahr by using method of FAO-56 and comparing the results assuming a shift in cropping pattern from rice to other crops. Rice water requirement was estimated at 1485 mm and the volume of water required for irrigation of paddy fields with area of about 6630 Hectare was estimated at 77 MCM. Volume of irrigated waterwas also evaluated by water balance method, confirmed the reliability of FAO-56 method. The results show that, replacing rice or wheat-rice cropping pattern with some possible crops such as bean, maize, walnut, apple and grape decreases irrigation requirements about 27, 15, 24, 29 and 40 MCM, respectively. Generalizing results for the total paddy fields in Isfahan Province with estimated area of about 20000 Hectare will result in an increase of about 3.4 to 9.1 m3/s in Zayandeh-rud discharge during critical months of June to October, when the river flow highly decreases, causing sustainable flow of the river through the year.

    Full Text Available The conception of sustainable development has been implemented into practice in numerous economic sectors, including forestry. Forest ecosystems are extremely important in the global ecological system, therefore maintenance and appropriate management of forest resources according to sustainable development principles have engaged a great deal of attention. The concept of sustainable forest management (SFM encompasses three dimensions: ecological, economic and social. A powerful tool to promote SFM are criteria and indicators. The aim of the article was evaluation of SFM in Poland, using one of the methods proposed by the Food and Agriculture Organization (FAO. According to data available, Polish forestry has a number of advantages: Poland has avoided the problem of deforestation, forest area has been permanently increasing, there has been observed improvement of forest health and vitality as well as a significant share of forests has carried out protective functions with no impact on timber production. Poland’s model of SFM is an adaptive process of balancing the ever-changing set of economic, environmental and social expectations. Such a complicated undertaking requires constant assessing and adjusting forest practices, in response to new circumstances, scientific advances and societal input

    Full Text Available Sustainability of agricultural production in the world is in serious crisis. Interdependence of agricultural production and the environment is multiple and causality works both ways. On one hand, there are environmental changes which hamper food production, and on the other, the agricultural production, as it is, is severely damaging the environment. The very systems of agricultural production jeopardize future production. The goal of this paper is to explore causes of limitations of sustainable agricultural development in the world, where the authors emphasize the following: gas emissions with greenhouse effect, a disturbed cycle of nitrogen circulation and destruction of biodiversity.

    2010-01-01

    Rapid population growth and the challenge of food security combined with burgeoning urban development have put multiple pressures on land and water resources. Worldwide soil degradation is currently estimated at 1.9 billion hectares and is increasing at a rate of 5 to 7 million hectares each year. Once land resources are degraded, rehabilitation usually requires a long-term effort and is often expensive. To mitigate land and soil degradation, effective soil conservation and suitable rehabilitation practices are required and should be chosen according to the levels and causes of soil degradation. The basic principles of soil conservation and management for preventing land degradation are: (i) to control soil erosion by practices such as terracing, reduced tillage in combination with mulching, intercropping or grass strips, (ii) to improve soil fertility through organic and inorganic fertilizers, and (iii) to prevent accumulation of harmful substances. Natural rehabilitation of degraded land can be a practical and low-cost alternative. For example, soil stabilization through vegetative measures has been used to control wind and water erosion and simultaneously improve soil health by increasing soil organic matter and nutrient availability. Nevertheless, if land has been degraded by mining and/or contaminated by heavy metals or organic pollutants, the surrounding farmlands can also be affected through surface runoff from the contaminated site, thereby rendering them unfit for cultivation. In this case, phytoremediation technologies, defined as the use of plants and trees to remove, immobilize, transform or degrade contaminants in polluted soil or water, in combination with for instance constructed wetlands and/or microbial interactions can be used to remediate polluted land as well as to prevent contamination of farmlands. Therefore both on-farm management and off-site remediation are important to protect and improve agricultural land resources, hence improve crop

    The ratification of Sustainable Development Goals (SDGs) by all member countries of the United Nations demonstrates the determination of the international community in moving towards a sustainable future. To enable and encourage accountability, independent and transparent measurements of national sustainability efforts are essential. Among all sectors, agriculture is fundamental to all three pillars of sustainability, namely environment, society, and economy. However, the definition of a sustainable agriculture and the feasibility of measuring it remain elusive, in part because it encompasses both biophysical and socio-economic components that are still poorly integrated. Therefore, we have been developing a Sustainable Agriculture Matrix (SAM) on a national scale in order to measure country-level performance in agriculture. First proposed by Swaminathan for agricultural research and policy in 1990s, SAM is a collection of indicators measuring sustainable agriculture from environmental, social, and economic dimensions. The environmental dimension evaluates various impacts of agricultural production on the environment, such as water consumption and nutrient pollution. The economic dimension quantifies the costs and benefits for major stakeholders involved in agricultural production, including government, industry, farmers, and consumers. The social dimension considers three major aspects: 1) social welfare (e.g., hunger and poverty rate, nutritional quality, demography of rural community); 2) equity over sectors, space, and gender (e.g., access to resources/services and opportunities, distribution of income, land ownership and tenure rights); 3) systemic risk (e.g., fragility of the global agricultural production and trade system, resilience of a farm or a country to market and natural shocks). Translating the illustrative concepts into measureable indicators will not only provide an independent and transparent measurement of national performance in the

    The progression of life in all forms is not only dependent on agricultural and food security but also on the soil characteristics. The dynamic nature of soil is a direct manifestation of soil microbes, bio-mineralization, and synergistic co-evolution with plants. With the increase in world's population the demand for agriculture yield has increased tremendously and thereby leading to large scale production of chemical fertilizers. Since the use of fertilizers and pesticides in the agricultural fields have caused degradation of soil quality and fertility, thus the expansion of agricultural land with fertile soil is near impossible, hence researchers and scientists have sifted their attention for a safer and productive means of agricultural practices. Plant growth promoting rhizobacteria (PGPR) has been functioning as a co-evolution between plants and microbes showing antagonistic and synergistic interactions with microorganisms and the soil. Microbial revitalization using plant growth promoters had been achieved through direct and indirect approaches like bio-fertilization, invigorating root growth, rhizoremediation, disease resistance etc. Although, there are a wide variety of PGPR and its allies, their role and usages for sustainable agriculture remains controversial and restricted. There is also variability in the performance of PGPR that may be due to various environmental factors that might affect their growth and proliferation in the plants. These gaps and limitations can be addressed through use of modern approaches and techniques such as nano-encapsulation and micro-encapsulation along with exploring multidisciplinary research that combines applications in biotechnology, nanotechnology, agro biotechnology, chemical engineering and material science and bringing together different ecological and functional biological approaches to provide new formulations and opportunities with immense potential.

    Full Text Available Knowledge based economy, found in more than one fields, started – considering agriculture – from a transition premise towards sustainable agro-food systems. The conceptual boundaries between the two major paradigms on sustainable development of agriculture, namely the agro-industrial paradigm and the integrated territorial paradigm, is used nowadays for teaching and research purpose, as a comparison basis with an ideal case, mostly because we only have hybrid models which tend to coexist, always improving the food and goods production, also promoting innovative agro-food systems. This paper highlights the idea that the establishment of an institutional and legal framework, will have a catalytic role acting as an engine of economic growth and boosting the development of agricultural systems by mobilizing entrepreneurs in agriculture and related areas. In this regard, we present best practices of economic actors engaged in meta network of agriculture clusters.

    The paper discusses the patents that have been filed in the areas of sustainable development in agriculture, food and nutrition and use of natural resources in achieving this goal. A large number of patents deal with the production of fertilizers from animal manure, plant sources and other organic wastes, which are more sustainable that the chemical fertilizers that are being currently used. Sustainability in agriculture is achieved in developing processes for the manufacture of biopesticides/insecticides and bioactive agricultural products. Development of novel sustainable agricultural processes has also been the focus of researchers and technologists. Plant derived nutritious food products are sustainable and can cater for the growing population burden. This has been the focus of several patents. Processes for enhancing the nutrition in food also serve the purpose of catering for the under nourished population.

    Full Text Available California's Mediterranean agro-ecosystems are a major source of U.S. fruits and vegetables, and vulnerable to future extremes of precipitation and temperature brought on by climate change, including increased drought and flooding, and more intense and longer heat waves. To develop resilience to these threats, strategies are necessary for climate-smart management of soil and water. Long-term, large-scale, replicated ecological experiments provide unique testbeds for studying such questions. At the UC Davis Russell Ranch Sustainable Agriculture Facility (RRSAF, the 100-year Century Experiment, initiated in 1992, is investigating the effects of multiple farming practices in a farm-scale replicated study of 10 row crop cropping systems. It includes different fertility management systems: organic, conventional and hybrid (conventional plus winter cover crop systems; different crops: wheat, tomatoes, corn, alfalfa, cover crops and grasslands; and different irrigation systems: rainfed, flood irrigated and drip irrigated. We briefly describe and report on a selection of long-term experiments conducted at RRSAF investigating soil management and irrigation practices, which are an important focus for developing climate-smart strategies in Mediterranean systems. For example, long-term monitoring of soil carbon content revealed that most crop systems have experienced a small increase in soil carbon since 1993, and increases in organically managed plots were substantially higher. As RRSAF continues to build upon this rich dataset from one of a very few long-term row crop experiments in Mediterranean ecosystems, it provides a testbed for identifying climate-smart solutions for these agronomically important ecosystems.

  3. Namibia specific climate smart agricultural land use practices: Challenges and opportunities for enhancing ecosystem services

    2015-04-01

    Agriculture is a backbone for many African economies, with an estimated 70% of Africans active in agricultural production. The sector often does not only directly contribute to, but sustains food security and poverty reduction efforts. Sustaining this productivity poses many challenges, particularly to small scale subsistence farmers (SSF) in dry land areas and semi-arid countries like Namibia. SSF in northern central Namibia mix crop and livestock production on degraded semi-arid lands and nutrient-poor sandy soils. They are fully dependent on agricultural production with limited alternative sources of income. Mostly, their agricultural harvests and outputs are low, not meeting their livelihood needs. At the same time, the land use is often not sustainable, leading to degradation. The Namibia case reveals that addressing underlying economic, social and environmental challenges requires a combination of farm level-soil management practices with a shift towards integrated landscape management. This forms the basis for SSF to adopt sustainable land management practices while building institutional foundations, like establishing SSF cooperatives. One way in which this has been tested is through the concept of incentive-based motivation, i.e. payment for ecosystem services (PES), in which some of the beneficiaries pay, for instance for farmers or land users, who provide the services. The farmers provide these services by substituting their unsustainable land and soil management and adopting new (climate smart agricultural) land use practices. Climate Smart Agricultural land use practices (CSA-LUP) are one way of providing ecosystem services, which could be fundamental to long-term sustainable soil and land management solutions in Africa. There are few PES cases which have been systematically studied from an institutional development structure perspective. This study presents lessons evolving from the notion that direct participation and involvement of local people

    Based on the ecological and economic problems in Good Agriculture Practice (GAP) of Chinese material medica, we introduced the origin, concept, features and operative technology of eco-agriculture worldwide, emphasizing its modes on different biological levels of landscape, ecosystem, community, population, individual and gene in China. And on this basis, we analyzed the background and current situation of eco-agriculture of Chinese materia medica, and proposed its development ideas and key tasks, including: (1) Analysis and planning of the production pattern of Chinese material medica national wide. (2) Typical features extraction of regional agriculture of Chinese materia medica. (3) Investigation of the interaction and its mechanism between typical Chinese materia medica in each region and the micro-ecology of rhizosphere soil. (4) Study on technology of eco-agriculture of Chinese materia medica. (5) Extraction and solidification of eco-agriculture modes of Chinese materia medica. (6) Study on the theory of eco-agriculture of Chinese materia medica. Also we pointed out that GAP and eco-agriculture of Chinese material medica are both different and relative, but they are not contradictory with their own features. It is an irresistible trend to promote eco-agriculture in the GAP of Chinese material medica and coordinate ecological and economic development.

    Sustaining food production, water quality, soil retention, flood, and climate regulation in agricultural landscapes is a pressing global challenge given accelerating environmental changes. Scenarios are stories about plausible futures, and scenarios can be integrated with biophysical simulation models to explore quantitatively how the future might unfold. However, few studies have incorporated a wide range of drivers (e.g., climate, land-use, management, population, human diet) in spatially explicit, process-based models to investigate spatial-temporal dynamics and relationships of a portfolio of ecosystem services. Here, we simulated nine ecosystem services (three provisioning and six regulating services) at 220 × 220 m from 2010 to 2070 under four contrasting scenarios in the 1,345-km 2 Yahara Watershed (Wisconsin, USA) using Agro-IBIS, a dynamic model of terrestrial ecosystem processes, biogeochemistry, water, and energy balance. We asked (1) How does ecosystem service supply vary among alternative future scenarios? (2) Where on the landscape is the provision of ecosystem services most susceptible to future social-ecological changes? (3) Among alternative future scenarios, are relationships (i.e., trade-offs, synergies) among food production, water, and biogeochemical services consistent over time? Our results showed that food production varied substantially with future land-use choices and management, and its trade-offs with water quality and soil retention persisted under most scenarios. However, pathways to mitigate or even reverse such trade-offs through technological advances and sustainable agricultural practices were apparent. Consistent relationships among regulating services were identified across scenarios (e.g., trade-offs of freshwater supply vs. flood and climate regulation, and synergies among water quality, soil retention, and climate regulation), suggesting opportunities and challenges to sustaining these services. In particular, proactive

  7. Developing Sustainable Agromining Systems in Agricultural Ultramafic Soils for Nickel Recovery

    Directory of Open Access Journals (Sweden)

    Petra Susan Kidd

    2018-06-01

    Full Text Available Ultramafic soils are typically enriched in nickel (Ni, chromium (Cr, and cobalt (Co and deficient in essential nutrients, making them unattractive for traditional agriculture. Implementing agromining systems in ultramafic agricultural soils represent an ecological option for the sustainable management and re-valorisation of these low-productivity landscapes. These novel agroecosystems cultivate Ni-hyperaccumulating plants which are able to bioaccumulate this metal in their aerial plant parts; harvested biomass can be incinerated to produce Ni-enriched ash or “bio-ore” from which Ni metal, Ni ecocatalysts or pure Ni salts can be recovered. Nickel hyperaccumulation has been documented in ~450 species, and in temperate latitudes these mainly belong to the family Brassicaceae and particularly to the genus Odontarrhena (syn. Alyssum pro parte. Agromining allows for sustainable metal recovery without causing the environmental impacts associated with conventional mining activities, and at the same time, can improve soil fertility and quality and provide essential ecosystem services. Parallel reductions in Ni phytotoxicity over time would also permit cultivation of conventional agricultural crops. Field studies in Europe have been restricted to Mediterranean areas and these only evaluated the Ni-hyperaccumulator Odontarrhena muralis s.l. Two recent EU projects (Agronickel and LIFE-Agromine have established a network of agromining field sites in ultramafic regions with different edapho-climatic characteristics across Albania, Austria, Greece and Spain. Soil and crop management practices are being developed so as to optimize the Ni agromining process; field studies are evaluating the potential benefits of fertilization regimes, crop selection and cropping patterns, and bioaugmentation with plant-associated microorganisms. Hydrometallurgical processes are being up-scaled to produce nickel compounds and energy from hyperaccumulator biomass. Exploratory

    The worldwide increase in human population raises a big threat to the food security of each people as the land for agriculture is limited and even getting reduced with time. Therefore, it is essential that agricultural productivity should be enhanced significantly within the next few decades to meet the large demand of food by emerging population. Not to mention, too much dependence on chemical fertilizers for more crop productions inevitably damages both environmental ecology and human health with great severity. Exploitation of microbes as biofertilizers is considered to some extent an alternative to chemical fertilizers in agricultural sector due to their extensive potentiality in enhancing crop production and food safety. It has been observed that some microorganisms including plant growth promoting bacteria, fungi, Cyanobacteria, etc. have showed biofertilizer-like activities in the agricultural sector. Extensive works on biofertilizers have revealed their capability of providing required nutrients to the crop in sufficient amounts that resulted in the enhancement of crop yield. The present review elucidates various mechanisms that have been exerted by biofertilizers in order to promote plant growth and also provides protection against different plant pathogens. The aim of this review is to discuss the important roles and applications of biofertilizers in different sectors including agriculture, bioremediation, and ecology.

  5. Identifying Best Practices for Engaging Faculty in International Agricultural Education

    2013-10-01

    Full Text Available Universities are being called upon to internationalize curriculum as the need for a globally competent workforce increases. Without globally-competent faculty, international integration within higher education cannot occur. Literature indicates that participation in short-term international agricultural education experiences is important to increasing agricultural faculty members’ cultural awareness. However, the best way to design and implement such experiences for faculty is uncharted. The purpose of the study was to identify best practices for facilitating a short-term international education experience for faculty in the agricultural and life sciences that encouraged learning, discussion, and reflection leading faculty to further integrate international perspectives in their agricultural courses in the U.S. Through a qualitative research design, reflective observations and statements from a planning team conducting short-term international agricultural education experience in Ecuador were used to provide a thick, rich description of the successes/challenges faced while designing and implementing the experience. The results provided a list of best practices future planning team members can use to emphasize learning before, during, and after a short-term international agricultural education experience for faculty.

    2017-06-01

    Full Text Available Despite the efforts for sustainability studies in building and infrastructure construction, the sustainability issues in industrial construction remain understudied. Further, few studies evaluate sustainability and benchmark sustainability issues in industrial construction from a management perspective. This study presents a phase-based benchmarking framework for evaluating sustainability practices use focusing on industrial facilities project. Based on the framework, this study quantifies and assesses sustainability practices use, and further sorts the results by project phase and major project characteristics, including project type, project nature, and project delivery method. The results show that sustainability practices were implemented higher in the construction and startup phases relative to other phases, with a very broad range. An assessment by project type and project nature showed significant differences in sustainability practices use, but no significant difference in practices use by project delivery method.

    Full Text Available Working lands have potential to meet agricultural production targets while serving as reservoirs of biological diversity and as sources of ecological services. Yet agricultural policy creates disincentives for this integration of conservation and production goals. While necessary, the development of a policy context that promotes agroecosystem sustainability will take time, and successful implementation will depend on a receptive agricultural audience. As the demands placed on working lands grow, there is a need for regional support networks that build agricultural producers' capacity for land stewardship. We used a social-ecological system framework to illustrate the Healthy Grown Potato Program as an agricultural network case study. Our Capacity-Building Stewardship Model reflects a 20-year experience working in collaboration with potato growers certified under an ecolabel in Wisconsin, USA. The model applies an evolving, modular farm stewardship standard to the entire farm - croplands and noncroplands. The model demonstrates an effective process for facilitating communication and shared learning among program participants, including agricultural producers, university extension specialists, nonprofit conservation partners, and industry representatives. The limitation of the model in practice has been securing funding to support expansion of the program and to ensure that the ecolabel standard is responsive to changes in the social-ecological system. Despite this constraint, the Capacity-Building Stewardship Model reveals an important mechanism for building regional commitment to conservation, with agricultural producers in a leadership role as architects, adopters, and advocates for stewardship behavior. Our experience provides important insight for the application of agri-environment schemes on private lands. The durability of a conservation ethic on working farms is likely to be enhanced when networks engage and support producers in an

    Full Text Available Agriculture land use right transfer (ALURT is a new policy designed to meet the demand of the sustainable development of agriculture in China. In the Heihe river basin (HRB, ALURT has also recently been introduced to cope with the emerging challenges in agriculture. In this paper, we empirically study the long-term viability of this new policy in HRB using a sustainability assessment. We collect the documents of ALURT contracts, statistical data of ALURT performance, and conduct interviews with its users. The main finding is that the centralized institutional structure of ALURT in HRB compromises its long-term viability. In particular, the power imbalance under the regulation of the intermediate agency, which causes the dissatisfaction of the participants, is threatening the application of the ALURT policy in the long run. Therefore, we suggest that the role of the intermediate agency in ALURT needs to be redefined, to better serve the sustainable development of agriculture in HRB.

    2013-06-05

    The Brazilian Amazon frontier shows how remarkable leadership can work towards increased agricultural productivity and environmental sustainability without new greenhouse gas emissions. This is due to initiatives among various stakeholders, including national and state government and agents, farmers, consumers, funding agencies and non-governmental organizations. Change has come both from bottom-up and top-down actions of these stakeholders, providing leadership, financing and monitoring to foster environmental sustainability and agricultural growth. Goals to reduce greenhouse gas emissions from land-cover and land-use change in Brazil are being achieved through a multi-tiered approach that includes policies to reduce deforestation and initiatives for forest restoration, as well as increased and diversified agricultural production, intensified ranching and innovations in agricultural management. Here, we address opportunities for the Brazilian Amazon in working towards low-carbon rural development and environmentally sustainable landscapes.

    ZHAO Qi-Guo; XU Meng-Jie

    2004-01-01

    Agricultural sustainability for economic development is important and a complex issue throughout the world; however,it is difficult to synthetically evaluate its use in the policy making process. The objective of this study was to evaluate sustainable agriculture in the red soil hill region of Southeast China through a newly proposed method combining four separate sub-systems: regional population (P), resource (R), environmental (E), and socio-economic (S). This new index system was proposed to appraise synthetically the agricultural sustainability of the red soil hill region from 1988 to 1996 with a two-step method assessing: a) the agricultural sustainability in each province independently and b) the relative sustainability of each province to the whole region. The first step only provided a development trend for each province based on its original situation, while the second step provided additional information on the comparative status of each province in agricultural development to the region as a whole. Higher index scores were found for the economy and resource categories denoting improvement. However, lower scores in the environment category indicated the improvement was achieved at the cost of deteriorating ecological surroundings due to an increasing population that demanded more from the agro-ecosystem and put heavier pressures on it. Results also showed that water and soil losses in this region were the major obstacles encountered in sustainable agriculture development. The assessment results were verified when compared with results from another method. This suggested that the new assessment system was reliable and credible in evaluating agricultural sustainability on a regional scale.

    In developed countries, changes in agriculture practices have greatly accelerated the degradation of the landscape and the functioning of adjacent aquatic ecosystems. Such alteration can in turn impair the services provided by aquatic ecosystems, namely the decomposition of organic matter, a key process in most small streams. To study this alteration, we recorded three measures of heterotrophic activity corresponding to microbial hydrolasic activity (FDA hydrolysis) and leaf litter breakdown rates with (k{sub c}) and without invertebrates (k{sub f}) along a gradient of contrasted agricultural pressures. Hydrolasic activity and k{sub f} reflect local/microhabitat conditions (i.e. nutrient concentrations and organic matter content of the sediment) but not land use while k{sub c} reflects land-use conditions. k{sub c}, which is positively correlated with the biomass of Gammaridae, significantly decreased with increasing agricultural pressure, contrary to the taxonomic richness and biomass of Trichoptera and Plecoptera. Gammaridae may thus be considered a key species for organic matter recycling in agriculture-impacted streams. - This study highlights the consequences of intensive agricultural practices on heterotrophic processes in streams along a strong gradient of perturbation.

    Byomkesh Talukder

    2017-02-01

    Full Text Available In the present world context, there is a need to assess the sustainability of agricultural systems. Various methods have been proposed to assess agricultural sustainability. Like in many other fields, Multi-Criteria Decision Analysis (MCDA has recently been used as a methodological approach for the assessment of agricultural sustainability. In this paper, an attempt is made to apply Elimination, a MCDA method, to an agricultural sustainability assessment, and to investigate its benefits and drawbacks. This article starts by explaining the importance of agricultural sustainability. Common MCDA types are discussed, with a description of the state-of-the-art method for incorporating multi-criteria and reference values for agricultural sustainability assessment. Then, a generic description of the Elimination Method is provided, and its modeling approach is applied to a case study in coastal Bangladesh. An assessment of the results is provided, and the issues that need consideration before applying Elimination to agricultural sustainability, are examined. Whilst having some limitations, the case study shows that it is applicable for agricultural sustainability assessments and for ranking the sustainability of agricultural systems. The assessment is quick compared to other assessment methods and is shown to be helpful for agricultural sustainability assessment. It is a relatively simple and straightforward analytical tool that could be widely and easily applied. However, it is suggested that appropriate care must be taken to ensure the successful use of the Elimination Method during the assessment process.

  7. Estimates of sustainable agricultural water use in northern China based on the equilibrium of groundwater

    Science.gov (United States)

    Yali, Y.; Yu, C.

    2015-12-01

    The northern plain is the important food production region in China. However, due to the lack of surface water resources, it needs overmuch exploitation of groundwater to maintain water use in agriculture, which leads to serious environmental problems. Based on the assumption that the reserves of groundwater matches the statistics and keeps on stable, the author explores the reasonable agricultural water and its spatial distribution based on the principle of sustainable utilization of water resources. According to the priorities of water resources allocation (domestic water and ecological water>industrial water>agricultural water), it is proposed to reduce agricultural water use to balance the groundwater reserves on condition that the total water supply is constant. Method: Firstly, we calculate annual average of northern groundwater reserves changes from 2004 to 2010, which is regarded as the reduction of agricultural water; Then, we estimate the food production changes using variables of typical crop water requirements and unit yields assuming that the efficiency of water use keeps the same during the entire study period; Finally, we evaluate the usage of sustainable agricultural water. The results reveal that there is a significant reduction of groundwater reserves in Haihe river basin and Xinjiang oasis regions; And the annual loss of the corn and wheat production is about 1.86 billion kg and 700 million kg respectively due to the reduction of agricultural water; What's more, in order to ensure China's food security and sustainable agricultural water use, in addition to great efforts to develop water-saving agriculture, an important adjustment in the distribution of food production is in need. This study provided a basis to the availability of agricultural water and a new perspective was put forth for an estimation of agricultural water.

    Brazil's large land base is important for global food security but its high dependency on inorganic phosphorus (P) fertilizer for crop production (2.2 Tg rising up to 4.6 Tg in 2050) is not a sustainable use of a critical and price-volatile resource. A new strategic analysis of current and future P demand/supply concluded that the nation's secondary P resources which are produced annually (e.g. livestock manures, sugarcane processing residues) could potentially provide up to 20% of crop P demand by 2050 with further investment in P recovery technologies. However, the much larger legacy stores of secondary P in the soil (30 Tg in 2016 worth over $40 billion and rising to 105 Tg by 2050) could provide a more important buffer against future P scarcity or sudden P price fluctuations, and enable a transition to more sustainable P input strategies that could reduce current annual P surpluses by 65%. In the longer-term, farming systems in Brazil should be redesigned to operate profitably but more sustainably under lower soil P fertility thresholds.

  10. The potential and sustainability of agricultural land use in a changing ecosystem in southern Greenland

    2015-04-01

    Southern Greenland currently experiences an increase in summer temperatures and a prolonged growing season (Masson-Delmotte et al. 2012), resulting in an increased potential regarding agricultural land use. Subsequently, the agricultural sector is expected to grow. Thereby, a higher hay production and grazing capacity is pursued by applying more efficient farming practices (Greenland Agriculture Advisory Board 2009). However, agricultural potential at borderline ecotones is not only influenced by factors like temperature and growing season but also by other ecologic parameters. In addition, the intensification of land use in the fragile boreal - tundra border ecotone has various environmental impacts (Perren et al. 2012; Normand et al. 2013). Already the Norse settlers practiced animal husbandry in southern Greenland between 986-1450 AD. Several authors mention the unadapted land use as main reason for the demise of the Norse in Greenland, as grazing pressure exceeded the resilience of the landscape and pasture economy failed (Fredskild 1988; Perren et al. 2012). During the field work in summer 2014, we compared the pedologic properties of already used hay fields, grazed land, birch woodland and barren, unused land around Igaliku (South Greenland), in order to estimate the potential and the sustainability of the land use in southern Greenland. Beside physical soil properties, nutrient condition of the different land use types, the shrub woodland and barren areas was analyzed. The results of the study show that the most suitable areas for intensive agricultural activity are mostly occupied. Further on, the fields, which were used by the Norse, seem to be the most productive sites nowadays. Less productive hay fields are characterized by a higher coarse fraction, leading to a reduced ability to store water and to an unfavorable nutrient status. An intensification of the agricultural land use by applying fertilizer would lead to an increased environmental impact

    2017-01-01

    Full Text Available The purpose of this research study is to investigate some of the sustainable practices within projects with a focus on social projects. The different research methodologies applied through this research consisted both primary and secondary research, including literature review and through case study. The stakeholder’s behavioural needs towards acting and implementing sustainable practices led to the adoption of sustainable practices within projects which are managed across profit and non-profit organisations. Nevertheless, lack of sustainable behaviour was outlined, and henceforth the integration of sustainable development within social projects is crucially important as such projects were identified as the drivers toward educating the society in order to help to produce generations of people who would be more sustainably aware. Currently, sustainable development is very often taken into account when it comes to managing projects. Nevertheless, if the adoption of sustainable practices is well established in some sectors such as construction, literature tends to demonstrate a lack of information regarding other sectors, especially within social projects. This research aims to investigate the adoption of sustainable practices within social projects and therefore to satisfy a literature gap.

  12. Recycling of Treated Sewage Sludge in Sustainable Agriculture

    Galal, Y.G.M.

    2012-01-01

    Agricultural utilization of organic wastes amendments has been shown to be a sound alternative for both waste recycling and soil fertility improvement. Also, attention had been paid to use the biological agents that most cheap and safe for agricultural application in poor sandy soils. In this respect, irradiated sewage sludge and individual and dual inoculants of Azospirillum, Rhizobium and Arbuscular mycorrhizae fungi were applied for reclamation and development of low fertile sandy soil. The fertilizer value of sewage sludge has been known for a long time, but the concomitant problems of heavy metals in soil, as a result of its continuous applications, have only been recognized recently. Most of the studies were devoted to follow up the effect of high concentrations of metals when sewage sludge was applied, but no attention has been accelerated about its effect on soil microorganisms. Adverse effects of sewage sludge on microbial activity and populations of cyanobacteria, Rhizobium, Mycorrhizae and total microbial biomass have been detected in some cases of Europe. For example, N 2 fixation by free-living heterotrophic bacteria was found to be inhibited at concentrations (mg kg -1 ) of 127 Zn, 37 Cu, 21 Ni, 3.4 Cd, 52 Cr, and 71 Pb. Impact of bio fertilizers combined with irradiated sewage sludge on micro nutrients, e.g. Fe, Zn, Mn, Pb availability to clover and wheat plants, and productivity of both crops was the main objective of this study. In this connection, nuclear technology may offer a safety method against pathogenic effects of sewage sludge applied into agricultural ecosystems. Therefore, irradiated sludge is considered as safely source of organic wastes as well as the benefits on enrichment the low fertile soil with available nutrients, which act as a limiting factor for crop production. The N, P and K nutrients uptake by either shoots or grains of tested crops were positively and significantly affected by application of sewage sludge as well as bio

    2018-03-01

    Full Text Available Marine macroalgae are plant-like organisms with simple internal structures that generally live in coastal areas. They mainly include different communities of red, brown and green macroalgae. Marine macroalgae commonly occupy intertidal and sublittoral-to-littoral zones on rocks and other hard substrata. They are considered to be an excellent natural biosource in different aspects of agricultural fields. They have great proficiency in improving soil physical and chemical properties. Marine macroalgae are also characterized by producing a large array of biologically active biocidal substances against plant-infecting pathogens. Unfortunately, most available literatures on marine macroalgae and their derivatives mainly focused on their pharmaceutical applications but their potential utilization in sustainable agriculture development is still often regarded as a secondary goal. However, a relatively considerable dataset on marine macroalgae showed that they could play a major role in plant protection and improvement. This review summarizes different aspects of potential macroalgal applications in agriculture. Commercial production and exploitation of specific compounds with interesting biotechnological importance from marine macroalgae including microbicides, nematicides, insecticides, biofertilizers, biostimulators and soil conditioners are highlighted and discussed in detail. Bioactive compounds like fatty acids (in particular polyunsaturated fatty acids (PUFAs, proteins (amino acids, bioflavonoids, sulfated polysaccharides, carotenoids, polyphenols and carbohydrates are considered to have bactericidal, antiviral and fungicidal effects against some plant-infecting pathogens. These biocontrol agents provide multiple benefits and act as useful pointers for improving cultivation practices in diverse habitats. Marine macroalgae can be generally considered as promising multifunctional bioinoculants and ecofriendly environmental tools in recent trends

  14. Utilization of Live Localized Weather Information for Sustainable Agriculture

    2010-09-01

    Authors: Jim Anderson VP, Global Network and Business Development WeatherBug® Professional Jeremy Usher Managing Director, Europe WeatherBug® Professional Localized, real-time weather information is vital for day-to-day agronomic management of all crops. The challenge for agriculture is twofold in that local and timely weather data is not often available for producers and farmers, and it is not integrated into decision-support tools they require. Many of the traditional sources of weather information are not sufficient for agricultural applications because of the long distances between weather stations, meaning the data is not always applicable for on-farm decision making processes. The second constraint with traditional weather information is the timeliness of the data. Most delivery systems are designed on a one-hour time step, whereas many decisions in agriculture are based on minute-by-minute weather conditions. This is especially true for decisions surrounding chemical and fertilizer application and frost events. This presentation will outline how the creation of an agricultural mesonet (weather network) can enable producers and farmers with live, local weather information from weather stations installed in farm/field locations. The live weather information collected from each weather station is integrated into a web-enabled decision support tool, supporting numerous on-farm agronomic activities such as pest management, or dealing with heavy rainfall and frost events. Agronomic models can be used to assess the potential of disease pressure, enhance the farmer's abilities to time pesticide applications, or assess conditions contributing to yield and quality fluctuations. Farmers and industry stakeholders may also view quality-assured historical weather variables at any location. This serves as a record-management tool for viewing previously uncharted agronomic weather events in graph or table form. This set of weather tools is unique and provides a

    Sustainable agricultural production relies on soil communities as the main actors in key soil processes necessary to maintain sustainable soil functioning. Soil biodiversity influences soil physical and chemical characteristics and thus the sustainability of crop and agro-ecosystems functioning. Agricultural practices (e.g.: soil tillage, pesticides and fertilizer applications, irrigation) may affects negatively or positively soil biodiversity and abundances by modifying the relationships between organisms in the soil ecosystem. The present study aimed to study the influence of agricultural practices of three crops (potato, onion and maize) under Mediterranean climate conditions on soil macro- and mesofauna during their entire crop cycles. Effects on soil communities were assessed at a higher tier of environmental risk assessment comprising field testing of indigenous edaphic communities in a selected study-site located in a major agriculture region of Central Portugal, Ribatejo e Oeste, neighbouring protected wetlands. A reference site near the agricultural field site was selected as a Control site to compare the terrestrial communities' composition and variation along the crop cycle. The field soil and Control site soil are sandy loam soils. Crops irrigation was performed by center-pivot (automated sprinkler that rotates in a half a circle area) and by sprinklers. Soil macro- and mesofauna were collected at both sites (field and Control) using two methodologies through pitfall trapping and soil sampling. The community of soil macro- and mesofauna of the three crops field varied versus control site along the crops cycles. Main differences were due to arachnids, coleopterans, ants and adult Diptera presence and abundance. The feeding activity of soil fauna between control site and crop areas varied only for potato and onion crops vs. control site but not among crops. Concentration of pesticides residues in soil did not cause apparent negative effects on the soil

    The rational use of soil requires the selection of management practices to take profit of the beneficial functions of plant growth, water and nutrient storage, and pollutants removal by filtering and decomposition without altering its properties. However, the first evidence of important and widespread erosion peaks can generally be found with the arrival of the first farmers all over the world. In areas with a long land-use history such as the Mediterranean, clear signs indicating the advanced degradation status of the landscape, such as heavily truncated soils, are visible throughout. Soil conservation practices are then aimed at reducing erosion to geological rates, in equilibrium with long-term soil formation rates, while maximizing agricultural production. The adoption of such practices in most areas of the world are as old as the earliest soil erosion episodes themselves. This work firstly reviews historical evidence linking soil management and soil erosion intensity, with examples from N Europe and the Mediterranean. In particular, work by the authors in olive orchards will be presented that shows how significant variations in soil erosion rates between could be linked to the historical soil management. The potential of historical documents for calibrating a soil erosion model is shown as the model, in this case RUSLE-based and combining tillage and water erosion, adequately represents the measured erosion rate dynamics. Secondly, results from present-day, long-term farm experiments in the EU are reviewed to evaluate the effect of different soil management practices on physical soil properties, such as bulk density, penetration resistance, aggregate stability, runoff coefficient or sediment yield. Finally, we reflect upon model and field data that indicate how future global climate change is expected to affect soil management and erosion and how the examples used above hold clues about sustainable historical management practices that can be used successfully

    Sembiring, Sri Alem Br

    2018-03-01

    This paper discusses how agricultural practices build social change in the Berastagi highlands. Agricultural products from this area are the vegetable supplier base for Medan City and other surrounding cities. The supply involves a network of trades involving many actors with many interests, as well as generating migration from other areas around and coming from different ethnicities. The migrants’ settlements are concentrated in certain areas of the region around Berastgai. This paper will illustrate the interaction between these aspects to bring about social change in Berastagi. This research uses qualitative method. Primary data were obtained through in-depth interview techniques and participant observation. Secondary data accessed from relevant agencies. This discussion shows how the pattern of social relationships changed due to changes in the goals of agricultural practices that not only oriented local markets but also exports. Competition, secrecy, and money orientation have become part of their planting activities. On the other hand, trade networks also construct them to work together in a particular context. This paper shows that agricultural activities and all things related to it reflect a broader context to see the development of small towns that also affect the development of the surrounding villages.

    Recent innovations in soil conservation methods do not present any breakthrough. Providing more attractive soil conservation methods from the farmer’s perspective is however still of critical importance. Contributing to this soil research gap we attempt to evaluate the sustainable use of three modified conservation methods, namely JALAPA (Jala Sabut Kelapa - geotextile made of coconut fibres), wood sediment trap, and polybag system compared to traditional tillage without conservation method. This research provides both qualitative and quantitative analysis on the performance of each conservation measures. Therefore, in addition to the total sediment yield value and investment cost – as quantitative analysis, we also evaluate qualitatively the indicator of soil loss, installation, maintenance, and the durability of conservation medium. Those criteria define the sustainability use of each conservation method. The results show that JALAPA is the most effective method for controlling soil loss, but it also requires the most expensive cost for installation. However, our finding confirms that geotextile is sensitive to sun heating by which the coconut fibre can become dry and shrink. Wood sediment trap is the cheapest and easiest to install; however it is easily damaged by termite. Polybag method results in the highest productivity, but requires more time during the first installation. In terms of the farmer’s perspective, soil conservation using polybag system was the most accepted technique due to its high benefits; even if it is less effective at reducing soil loss compared to JALAPA.

    Full Text Available Due to the low compliance of greenhouse production with the principles of sustainable agriculture, a meaningful effort in this regard needs to be done. One of the important factors affecting the success of future planning is the positive attitude of greenhouse owners toward sustainable agriculture. The purpose of this descriptive- correlational study was to investigate factors affecting greenhouse owners’ attitude toward sustainable agriculture. The validity of the questionnaire was verified by a panel of experts in the related field and to obtain its reliability, calculated alpha Cronbach coefficient was higher than 0.75 for different parts. The statistical population consisted all greenhouse owners in Zanjan province (N=80 and based on Krejci and Morgan sampling Table and using randomized sampling method 66 greenhouse owners selected. Results showed that majority of greenhouse owner use moderately of information channels and mass media. The majority of greenhouse owners (59.6 percent had a medium level of knowledge regarding sustainable agriculture and Majority of them (73.7 percent had a positive attitude toward sustainable agriculture. Correlation coefficient showed that greenhouse owners’ attitude had a positive meaningful correlation with information using level, income from the greenhouse, number of educational classes and their job satisfaction but a negative meaningful correlation with the number of household members participating in the activity. Regression analysis revealed that five variable of information using level, the number of household members participating in activity, knowledge and daily time spending in the greenhouse were explained 55.4 percent of greenhouse owners’ attitude toward sustainable agriculture.

    Full Text Available Abstract Land degradation is the most chronic problem in the Ethiopia. Soil erosion and denudation of vegetation covers are tending to enlarge the area of degraded and west land in semi-arid watersheds. It is therefore watershed management is believed as a holistic approach to create a climate smart landscape that integrate forestry agriculture pasture and soil water management with an objective of sustainable management of natural resources to improve livelihood. This approach pursues to promote interactions among multiple stakeholders and their interests within and between the upstream and downstream locations of a watershed. Melkassa Agricultural Research Centre MARC has been implementing integrated watershed management research project in the Jogo-gudedo watershed from 2010-2014 and lessons from Jogo-gudedo watershed are presented in this research report. Participatory action research PAR was implemented on Soil and Water Conservation SWC area enclosure Agroforestry AF Conservation Tillage CT energy saving stove drought resistance crop varieties in the Jogo-gudedo watershed. Empirical research and action research at plot level and evaluation of introduced technologies with farmers through experimental learning approach and documentation were employed. The participatory evaluation and collective action of SWC and improved practices brought high degree of acceptance of the practices and technologies. This had been ratified by the implementation of comprehensive watershed management action research which in turn enabled to taste and exploit benefits of climate-smart agricultural practices. Eventually significant reduction on soil loss and fuel wood consumption improvements on vegetation cover and crop production were quantitatively recorded as a good indicator and success. Field visit meetings trainings and frequent dialogues between practitioners and communities at watershed level have had a help in promoting the climate smart agriculture

  3. Considering the normative, systemic and procedural dimensions in indicator-based sustainability assessments in agriculture

    Binder, Claudia R.; Feola, Giuseppe; Steinberger, Julia K.

    2010-01-01

    This paper develops a framework for evaluating sustainability assessment methods by separately analyzing their normative, systemic and procedural dimensions as suggested by Wiek and Binder [Wiek, A, Binder, C. Solution spaces for decision-making - a sustainability assessment tool for city-regions. Environ Impact Asses Rev 2005, 25: 589-608.]. The framework is then used to characterize indicator-based sustainability assessment methods in agriculture. For a long time, sustainability assessment in agriculture has focused mostly on environmental and technical issues, thus neglecting the economic and, above all, the social aspects of sustainability, the multi-functionality of agriculture and the applicability of the results. In response to these shortcomings, several integrative sustainability assessment methods have been developed for the agricultural sector. This paper reviews seven of these that represent the diversity of tools developed in this area. The reviewed assessment methods can be categorized into three types: (i) top-down farm assessment methods; (ii) top-down regional assessment methods with some stakeholder participation; (iii) bottom-up, integrated participatory or transdisciplinary methods with stakeholder participation throughout the process. The results readily show the trade-offs encountered when selecting an assessment method. A clear, standardized, top-down procedure allows for potentially benchmarking and comparing results across regions and sites. However, this comes at the cost of system specificity. As the top-down methods often have low stakeholder involvement, the application and implementation of the results might be difficult. Our analysis suggests that to include the aspects mentioned above in agricultural sustainability assessment, the bottom-up, integrated participatory or transdisciplinary methods are the most suitable ones.

    2015-12-01

    Full Text Available Coastal tourism destinations are reinventing themselves, concentrating on product improvement and image enhancement. Reinventing sustainably is key and restaurants are an important factor. Research upon the processes of change in the industry seems to be fragmented and undefined in its conclusions. Knowledge is lacking on what specifically drives innovation in the hospitality industry. Since restaurants seem to be focusing more than ever on implementing green strategies, incorporating sustainability into restaurant practices is not an unexplored area. However, the how and why it is incorporated or not, can be different per restaurant. The objective of this study is to identify possibilities of change in restaurateur practices, which can lead to interventions that will foster sustainable destination development in Vrouwenpolder; a coastal destination within the Netherlands. For the identification of interventions that could advance the sustainability enacted in restaurateur practices, a qualitative research was conducted. Practices of restaurateurs in Vrouwenpolder are identified and compared to perceived-to-be ideal practices. Analysis of data collection draws on practice theory, and resulted into recommendations for advancing the sustainability enacted in restaurateur practices. It seems to be that primarily the meaning within a practice is decisive in whether sustainability is integrated or not.

    2011-08-01

    Agricultural residues have significant potential as a feedstock for bioenergy production, but removing these residues can have negative impacts on soil health. Models and datasets that can support decisions about sustainable agricultural residue removal are available; however, no tools currently exist capable of simultaneously addressing all environmental factors that can limit availability of residue. The VE-Suite model integration framework has been used to couple a set of environmental process models to support agricultural residue removal decisions. The RUSLE2, WEPS, and Soil Conditioning Index models have been integrated. A disparate set of databases providing the soils, climate, and management practice data required to run these models have also been integrated. The integrated system has been demonstrated for two example cases. First, an assessment using high spatial fidelity crop yield data has been run for a single farm. This analysis shows the significant variance in sustainably accessible residue across a single farm and crop year. A second example is an aggregate assessment of agricultural residues available in the state of Iowa. This implementation of the integrated systems model demonstrates the capability to run a vast range of scenarios required to represent a large geographic region.

  8. Sustainable energy, environmental and agricultural policies in Turkey

    2010-01-01

    Turkey's demand for energy and electricity is increasing rapidly and heavily dependent on expensive imported energy resources that place a big burden on the economy and air pollution is becoming a great environmental concern in the country. As would be expected, the rapid expansion of energy production and consumption has brought with it a wide range of environmental issues at the local, regional and global levels. With respect to global environmental issues, Turkey's carbon dioxide (CO 2 ) emissions have grown along with its energy-consumption. States have played a leading role in protecting the environment by reducing emissions of greenhouse gases (GHGs). In this regard, renewable energy resources appear to be the one of the most efficient and effective solutions for clean and sustainable energy development in Turkey. Turkey's geographical location has several advantages for extensive use of most of these renewable energy sources.

  9. Deficit irrigation and sustainable water-resource strategies in agriculture for China's food security.

    2015-04-01

    More than 70% of fresh water is used in agriculture in many parts of the world, but competition for domestic and industrial water use is intense. For future global food security, water use in agriculture must become sustainable. Agricultural water-use efficiency and water productivity can be improved at different points from the stomatal to the regional scale. A promising approach is the use of deficit irrigation, which can both save water and induce plant physiological regulations such as stomatal opening and reproductive and vegetative growth. At the scales of the irrigation district, the catchment, and the region, there can be many other components to a sustainable water-resources strategy. There is much interest in whether crop water use can be regulated as a function of understanding of physiological responses. If this is the case, then agricultural water resources can be reallocated to the benefit of the broader community. We summarize the extent of use and impact of deficit irrigation within China. A sustainable strategy for allocation of agricultural water resources for food security is proposed. Our intention is to build an integrative system to control crop water use during different cropping stages and actively regulate the plant's growth, productivity, and development based on physiological responses. This is done with a view to improving the allocation of limited agricultural water resources. © The Author 2015.

    Full Text Available The attitude of greenhouse owner as the basis of agricultural production towards sustainable agriculture could be grounds for increasing the sustainability of this type of cultivation system. Therefore, the main purpose of this study is to investigate the factors affecting the attitude of greenhouse owners towards sustainability in the Alborz province. The target population for this study consisted of all active greenhouse owners in the Alborz province (N=366. The sample size was determined by using Cochran’s formula (n=155 and using the proportional stratified random sampling method. The validity was confirmed by a panel of experts and its reliability was established by Cronbach's Alpha coefficient (0.85. The results showed that the attitude of 41 percent of the respondents towards sustainability was positive. Also, there were significant differences between the attitudes of the respondents in the group with related education and unrelated education group. Correlation analysis showed that the there is a positive relation between attitude towards searching behavior and the use of communication channels. In addition, the results of multiple regression analysis indicated that about 40 percent of the attitudes of greenhouse owner towards sustainable agriculture are explained by 4 variables. The result of this study indicate that by using different means of providing information and training, we can change the attitudes of greenhouse owners and lead them to produce more sustainable and healthy product.

  14. McSustainability and McJustice: Certification, Alternative Food and Agriculture, and Social Change

    Directory of Open Access Journals (Sweden)

    Maki Hatanaka

    2014-11-01

    Full Text Available Alternative food and agriculture movements increasingly rely on market-based approaches, particularly voluntary standards and certification, to advance environmental sustainability and social justice. Using a case study of an ecological shrimp project in Indonesia that became certified organic, this paper raises concerns regarding the impacts of certification on alternative food and agriculture movements, and their aims of furthering sustainability and justice. Drawing on George Ritzer’s McDonaldization framework, I argue that the ecological shrimp project became McDonaldized with the introduction of voluntary standards and certification. Specifically, efficiency, calculability, predictability, and control became key characteristics of the shrimp project. While the introduction of such characteristics increased market access, it also entailed significant costs, including an erosion of trust and marginalization and alienation of farmers. Given such tradeoffs, in concluding I propose that certification is producing particular forms of environmental sustainability and social justice, what I term McSustainability and McJustice. While enabling the expansion of alternative food and agriculture, McSustainability and McJustice tend to allow little opportunity for farmer empowerment and food sovereignty, as well as exclude aspects of sustainable farming or ethical production that are not easily measured, standardized, and validated.

    2017-08-01

    In rapidly urbanizing semi-arid regions, increasing amounts of historically irrigated cropland lies permanently fallowed due to water court policies as agricultural water rights are voluntarily being sold to growing cities. This study develops an integrative framework for assessing the effects of population growth and land use change on agricultural production and evaluating viability of alternative management strategies, including alternative agricultural transfer methods, regional water ownership restrictions, and urban conservation. A partial equilibrium model of a spatially-diverse regional water rights market is built in application of the framework to an exemplary basin. The model represents agricultural producers as profit-maximizing suppliers and municipalities as cost-minimizing consumers of water rights. Results indicate that selling an agricultural water right today is worth up to two times more than 40 years of continued production. All alternative policies that sustain agricultural cropland and crop production decrease total agricultural profitability by diminishing water rights sales revenue, but in doing so, they also decrease municipal water acquisition costs. Defining good indicators and incorporating adequate spatial and temporal detail are critical to properly analyzing policy impacts. To best improve agricultural profit from production and sale of crops, short-term solutions include alternative agricultural transfer methods while long-term solutions incorporate urban conservation.

  2. Agricultural use of treated municipal wastewaters preserving environmental sustainability

    2007-07-01

    Full Text Available In this paper the utility of the treated municipal wastewaters in agriculture, analyzing the chemical, physical and microbiological characteristics and their pollution indicators evaluation are being illustrated. Some methods employed for treating wastewaters are examined, as well as instructions and rules actually in force in different countries of the world, for evaluating the legislative hygienic and sanitary and agronomic problems connected with the treated wastewaters use, are being collected and compared. Successively, in order to provide useful indications for the use of treated municipal wastewaters, results of long-term field researches, carried out in Puglia, regarding two types of waters (treated municipal wastewater and conventional water and two irrigation methods (drip and capillary sub-irrigation on vegetable crops grown in succession, are being reported. For each crop cycle, chemical physical and microbiological analyses have been performed on irrigation water, soil and crop samples. The results evidenced that although irrigating with waters having high colimetric values, higher than those indicated by law and with two different irrigation methods, never soil and marketable yield pollutions have been observed. Moreover, the probability to take infection and/or disease for ingestion of fruits coming from crops irrigated with treated wastewaters, calculated by Beta-Poisson method, resulted negligible and equal to 1 person for 100 millions of exposed people. Concentrations of heavy metals in soil and crops were lesser than those admissible by law. The free chlorine, coming from disinfection, found in the wastewaters used for watering, in some cases caused toxicity effects, which determined significant yield decreases. Therefore, municipal wastewaters, if well treated, can be used for irrigation representing a valid alternative to the conventional ones.

    2016-04-01

    The world water strategy is to be changed because the current imitational gravitational frontal isotropic-continual paradigm of irrigation is not sustainable. This paradigm causes excessive consumption of fresh water - global deficit - up to 4-15 times, adverse effects on soils and landscapes. Current methods of irrigation does not control the water spread throughout the soil continuum. The preferable downward fluxes of irrigation water are forming, up to 70% and more of water supply loses into vadose zone. The moisture of irrigated soil is high, soil loses structure in the process of granulometric fractions flotation decomposition, the stomatal apparatus of plant leaf is fully open, transpiration rate is maximal. We propose the Biogeosystem technique - the transcendental, uncommon and non-imitating methods for Sustainable Natural Resources Management. New paradigm of irrigation is based on the intra-soil pulse discrete method of water supply into the soil continuum by injection in small discrete portions. Individual volume of water is supplied as a vertical cylinder of soil preliminary watering. The cylinder position in soil is at depth form 10 to 30 cm. Diameter of cylinder is 1-2 cm. Within 5-10 min after injection the water spreads from the cylinder of preliminary watering into surrounding soil by capillary, film and vapor transfer. Small amount of water is transferred gravitationally to the depth of 35-40 cm. The soil watering cylinder position in soil profile is at depth of 5-50 cm, diameter of the cylinder is 2-4 cm. Lateral distance between next cylinders along the plant raw is 10-15 cm. The soil carcass which is surrounding the cylinder of non-watered soil remains relatively dry and mechanically stable. After water injection the structure of soil in cylinder restores quickly because of no compression from the stable adjoining volume of soil and soil structure memory. The mean soil thermodynamic water potential of watered zone is -0.2 MPa. At this potential

    Full Text Available By transition process, which is presented in the Republic of Serbia for many years, rural areas are also covered in great extent. Changes in national agricultural policy, in terms of orientation towards rural development and multifunctional agriculture, have led to situation that process of development must involve all stakeholders, from governmental institutions, via local community, to population of rural areas. Such approach to rural development could initiate easier integration into international institutions and European Union, as well as to strengthening of cross-border cooperation within the mentioned area of economy. The most part of the Carpathians in the Republic of Serbia is taken by the national park „Đerdap“ and its protected zone. Within the mentioned protected area, sustainable use of agricultural land is based on traditional system of mountain agriculture that provides a high degree of ecological rationality and represents a very good foundation for development of integral and organic production.Opening toward the international community and peculiarly clear commitment of Serbia to European integrations,requires a new definition of role and importance of agricultural sector. Therefore, it is estimated that now is the perfect time for establishment of concrete conceptual framework and Strategy that will answer to key questions within the agro-food sector. In this context, authors’ intention (they are also the members of the research team of IAE Belgrade which is the holder of the project III 46006 - Sustainable agriculture and rural development in function of Republic of Serbia strategic goals achievement within the Danube region is to evaluate a social sustainability of agriculture in the area of the Carpathians in Serbia. Because of that, research is focused to administrative area of next municipalities: Golubac, Kučevo, Majdanpek, Kladovo and Negotin. Considering microeconomic character of research, it was used the

    2009-01-01

    Despite the advance of sustainable practice and energy efficient techniques outside of the nuclear industry, at the start of the 21. Century there was a lack of published guidance aimed at their adoption at specifically nuclear facilities. Even with the establishment of the Nuclear Decommissioning Authority, there is very little guidance published on how to adopt sustainable practices during decommissioning. There have been instances where energy efficiency had affected design and operations decisions. Projects aimed at responsible housekeeping, switching off lights, and changes to the nuclear ventilation design philosophy illustrate a desire for action, but these activities were championed by interested and motivated employees. Sustainable practice had not at that time received a strategic lead that resulted in a management structure to enable a coordinated and concerted effort in sustainable practice. This paper traces the progress during the 20. and early 21. Centuries, whereby sustainable practice is now established within a much firmer foundation of case study, guidance and organisational structure; to embed sustainable practice within the United Kingdom's current decommissioning programme. It looks at the development of relevant literature and, through interviews with key managers and external stakeholders, demonstrates (i) the degree to which two essential guidance documents (the NiCOP and CIRIA SD:SPUR) are permeating the industry, (ii) how the current work of the Characterisation and Clearance Group has evolved to influence the decontamination and dismantling planning procedures and (iii) the transition from identifying 'free-release' materials to actually releasing them for re-use in the community.

    The financial crisis in 2007-2008 and the subsequent economic crisis served as a wake-up call for sustainable consumption studies. The literature on consumption and environment had little focus on finance, but the crisis made it clear that financial issues are important also from an environmental...... perspective. Credit plays an important role as a driver of unsustainable consumption, and financial mechanisms contribute to the widening inequalities as well as the build-up of macroeconomic instability. Looking ahead, transformation of finance is just as important for sustainability as transformation...... of the provision systems for food, transport, housing, etc. that are the dominant focus of environmental studies. Intertwined with these systems, the economy includes various other systems that are decisive for the overall economic and environmental performance and for the distribution of goods and services...

  14. Agricultural and Food Production in Hungary: On the Road to Sustainability

    Directory of Open Access Journals (Sweden)

    2017-11-01

    Full Text Available In the last 25 years Hungarian agriculture has lost its position. Rapid growth in the world’s population requires an increase in food production since one seventh of the population is still starving. The development of agricultural production and the food industry is the basis for the development of rural areas. Hungary produces two per cent of the EU agricultural output, which is far behind its potential. Agriculture, food industry and food trade can only develop together. We need to find the most favourable forms of coexistence with multinational chains sustainably. Food industry is a critical point in the product line, it lags behind the performance of European countries, and resources are insufficient. Long-term co-operation between farmers and processors is inadequate; the common organizations of the markets are minimal. Today, sustainability is increasingly emphasized, environmental and nature protection has been appreciated. The agriculture and forestry sectors are not only suitable for production of food and other raw materials, but they can also replenish resources and have a beneficial effect on biodiversity as well. Today’s problems can only be solved by taking sustainability into consideration. Agri-food industry that complies with the requirements can play a major role in rural employment and value creation.

    2018-03-01

    While sustainability is a key concept in many different domains today, it has not yet been sufficiently emphasized in the healthcare sector. Earlier research shows that ethical values and evidence-based care models create sustainability in care practice. The aim of this study was to gain further understanding of the ethical values central to the realization of sustainability in care and to create an ethical practice model whereby these basic values can be made perceptible and active in care practice. Part of the ongoing "Ethical Sustainable Caring Cultures" research project, a hermeneutical application research design was employed in this study. Dialogues were used, where scientific researchers and co-researchers were given the opportunity to reflect on ethical values in relation to sustainability in care. An ethical practice model with ethos as its core was created from the results of the dialogues. In the model, ethos is encircled by the ethical values central to sustainability: dignity, responsibility, respect, invitation, and vows. The model can be used as a starting point for ethical conversations that support carers' reflections on the ethical issues seen in day-to-day care work and the work community, allowing ethical values to become visible throughout the entire care culture. It is intended as a tool whereby carers can more deeply understand an organization's common basic values and what they entail in regard to sustainability in care.

  18. Green House Gas Control and Agricultural Biomass for Sustainable Animal Agriculture in Developing Countries

    2010-06-01

    Full Text Available Important green house gases (GHG attributed to animal agriculture are methane (CH4 and nitrous oxide (N2O, though carbon dioxide (CO2 contributes almost half of total greenhouse effect. Rumen CH4 production in an enteric fermentation can be accounted as the biggest anthropogenic source. Some of prebiotics and probiotics have been innovated to mitigate rumen CH4 emission. The possible use of agricultural biomass consisted of non-edible parts of crop plants such as cellulose and hemi cellulose and animal wastes was proposed as a renewable energy and nitrogen sources. The ammonia stripping from digested slurry of animal manure in biogas plant applied three options of nitrogen recycling to mitigate nitrous oxide emission. In the first option of the ammonia stripping, the effect of ammonolysis on feed value of cellulose biomass was evaluated on digestibility, energy metabolism and protein utilization. Saccharification of the NH3 treated cellulose biomass was confirmed in strictly anaerobic incubation with rumen cellulolytic bacteria, Ruminoccous flavefaciens, to produce bio-ethanol as the second option of ammonia stripping. In an attempt of NH3 fuel cell, the reformed hydrogen from the NH3 stripped from 20 liter of digested slurry in thermophilic biogas plant could generate 0.12 W electricity with proton exchange membrane fuel cell (PEM as the third option.

    Organic production and consumption provide a delineated food system that can be explored for its potential contribution to sustainable diets. While organic agriculture improves the sustainability performance on the production side, critical reflections are made on how organic consumption patterns, understood as the practice of people consuming significant amounts of organic produce, may also be taken as an example for sustainable food consumption. The consumption patterns of regular organic consumers seem to be close to the sustainable diet concept of FAO. Certain organic-related measures might therefore be useful in the sustainability assessment of diets, e.g., organic production and organic consumption. Since diets play a central role in shaping food systems and food systems shape diets, the role of organic consumption emerges as an essential topic to be addressed. This role may be based on four important organic achievements: organic agriculture and food production has a definition, well-established principles, public standards, and useful metrics. By 2015, data for organic production and consumption are recorded annually from more than 160 countries, and regulations are in force in more than 80 countries or regions. The organic food system puts the land (agri-cultura) back into the diet; it is the land from which the diet in toto is shaped. Therefore, the organic food system provides essential components of a sustainable diet.

  3. Giving sustainable agriculture really good odds through innovative rainfall index insurance

    2017-12-01

    Population growth, increasing demands for food, and increasingly uncertain and limited water availability amidst competing demands for water by other users and the environment call for a novel approach to manage water in food production systems to be developed now. Tapping into broad popularity of crop insurance as a risk management intervention, we propose an innovative rainfall index insurance program as a novel systems approach that addresses water conservation in food production systems by exploiting two common currencies that tie the food production systems and others together, namely water and money. Our novel methodology allows for optimizing diverse farm and financial strategies together, revealing strategy portfolios that result in greater water use efficiency and higher incomes at a lower level of water use. Furthermore, it allows targeted interventions to achieve reduction in irrigation water, while providing financial protection to farmers against the increasing uncertainty in water availability. Not only would such a tool result in efficiently less use of water, it would also encourage diversification in farm practices, which reduces the farm's vulnerability against crop price volatility and pest or disease outbreaks and contributes to more sustainable agriculture.

    The creation of a sustainable future depends on the knowledge and involvement of the people, as well as an understanding of the consequences of individual actions. To implement sustainable construction effectively, the construction practitioners must be willing to change their behaviour in exploring new territory and willing to adopt new products, ideas and practices. In Malaysia, the issues of environmental dissatisfaction on construction projects regularly appeared in headlines. These negative remarks about construction tainted the good image of the industry. Due to the growing concern on environment, the government, professional bodies and private companies are beginning to take proactive approach to reduce this problem without restraining the need for development. There is some evidence of sustainable projects being built in Malaysia indicating that the concept of sustainable construction has beginning to settle within the industry. However, these projects are pioneers and merely fingers count. As global interest on sustainability has steadily blooming, Malaysia should not fell short in its attitude on sustainability and sustainable construction. Are we ready to make our commitment for sustainability in the global market? This paper focuses on the actions undertaken by the Malaysian government, non-government organisations and construction players in promoting sustainability in construction. To ensure that those concerted efforts are not only skin deep in its impact, a survey was conducted to investigate the awareness of the developers regarding this issue and whether those developers has absorb the concept of sustainable construction in their current practices. The survey revealed that although the developers are aware of the rising issues on sustainability, little efforts are generated from the developers in implementing it. More effort is necessary to boost this application and further stimulate actions and strategies towards a sustainable built environment.

  5. Environmental Sustainability of Agriculture Stressed by Changing Extremes of Drought and Excess Moisture: A Conceptual Review

    Full Text Available As the climate changes, the effects of agriculture on the environment may change. In the future, an increasing frequency of climate extremes, such as droughts, heat waves, and excess moisture, is expected. Past research on the interaction between environment and resources has focused on climate change effects on various sectors, including agricultural production (especially crop production, but research on the effects of climate change using agri-environmental indicators (AEI of environmental sustainability of agriculture is limited. The aim of this paper was to begin to address this knowledge gap by exploring the effects of future drought and excess moisture on environmental sustainability of agriculture. Methods included the use of a conceptual framework, literature reviews, and an examination of the climate sensitivities of the AEI models. The AEIs assessed were those for the themes of soil and water quality, and farmland management as developed by Agriculture and Agri-Food Canada. Additional indicators included one for desertification and another for water supply and demand. The study area was the agricultural region of the Canadian Prairie Provinces. We found that the performance of several indicators would likely decrease in a warming climate with more extremes. These indicators with declining performances included risks for soil erosion, soil salinization, desertification, water quality and quantity, and soil contamination. Preliminary trends of other indicators such as farmland management were not clear. AEIs are important tools for measuring climate impacts on the environmental sustainability of agriculture. They also indicate the success of adaptation measures and suggest areas of operational and policy development. Therefore, continued reporting and enhancement of these indicators is recommended.

    The United States Food and Drug Administration and the Department of Agriculture jointly published the "Guide to Minimize Microbial Food Safety Hazards for Fresh Fruits and Vegetables," which is used as a basis for Good Agricultural Practices (GAP) audits. To understand barriers to incorporation of GAP by Minnesota vegetable farmers, a mail survey completed in 2008 was validated with visits to a subset of the farms. This was done to determine the extent to which actual practices matched perceived practices. Two hundred forty-six producers completed the mail survey, and 27 participated in the on-farm survey. Over 75% of the on-farm survey respondents produced vegetables on 10 acres or less and had 10 or fewer employees. Of 14 questions, excellent agreement between on-farm interviews and mail survey responses was observed on two questions, four questions had poor or slight agreement, and eight questions had no agreement. Ninety-two percent of respondents by mail said "they took measures to keep animals and pests out of packing and storage buildings." However, with the on-site visit only 45% met this requirement. Similarly, 81% of respondents by mail said "measures were taken to reduce the risk of wild and/or domestic animals entering into fruit and vegetable growing areas." With direct observation, 70% of farms actually had taken measures to keep animals out of the growing areas. Additional, on-farm assessments were done regarding employee hygiene, training, presence of animals, water sources, and composting practices. This validation study demonstrated the challenge of creating nonleading and concise questions that are not open to broad interpretation from the respondents. If mail surveys are used to assess GAP, they should include open-ended questions and ranking systems to better assess farm practices. To provide the most accurate survey data for educational purposes or GAP audits, on-farm visits are recommended.

  7. The Implementation of the Food Safety Modernization Act and the Strength of the Sustainable Agriculture Movement.

    Science.gov (United States)

    Wiseman, Samuel R

    2015-01-01

    In the wake of growing public concerns over salmonella outbreaks and other highly publicized food safety issues, Congress passed the FDA Food Safety Modernization Act in 2011, which placed more stringent standards on food growing and packaging operations. In negotiations preceding the Act's passage, farmers of local, sustainable food argued that these rules would unduly burden local agricultural operations or, at the extreme, drive them out of business by creating overly burdensome rules. These objections culminated in the addition of the Tester-Hagan Amendment to the Food Safety Modernization Act, which created certain exemptions for small farms. Proposed Food and Drug Administration (FDA) rules to implement the Act threatened to weaken this victory for small farm groups, however, prompting a loud response from small farmers and local food proponents. The FDA's second set of proposed rules, issued in September 2014 in response to these and other complaints, were, perhaps surprisingly, responsive to small farmers' concerns. Using comments submitted to the FDA, this article explores the responses of the agriculture industry and public health organizations, as well as small farm groups, consumers of local food, and sustainable agriculture interests (which, for simplicity, I alternately describe as comprising the "sustainable agriculture" or "small farm" movement), to three aspects of the FDA's proposed rules--involving manure application, on-farm packing activities, and exemptions for very small farms--to assess the strength of the sustainable agriculture movement. The rules involving manure application and on-farm packing, it turns out, reveal little about the independent political strength of the local food movement, as large industry groups also objected to these provisions. But for the third issue discussed here--exemptions for very small farms--the interests of sustainable agriculture groups were directly opposed to both industry and public health organizations

    2009-01-01

    Full Text Available Agricultural production in developed countries undergoes various changes, some of which take place at consumers’ request, while others are of ethical importance. This is especially true of plant protection. A global demand for reducing the use of chemical pesticides, which are regarded as harmful to the consumer, induce the developement of new, less harmful and sustainable strategies of plant protection. Many chemical pesticides have been excluded from further use (e.g. organochlorine insecticides, methyl bromide due totheir potential risk to human health, the environment and non-target organisms, or developement of resistance of harmful organisms to those substances. A need for developing alternative protection systems in the future is beyond doubt and they should be implementedeither as an addition or a substitute for conventional pesticides. Well-considered use of biological products in combination with other protection measures would meet the requirements for producing sanitary and health-safe agricultural products, and food in general. In the paper, we discuss the modes of action, formulation types and applicability of different biological fungicides, and list them individually with their advantages and disadvantages, as well as the production and application risks associated with biological products.

    Today, urban agriculture is one of the most widely used sustainability strategies to improve the metabolism of a city. Schools can play an important role in the implementation of sustainability master plans, due their socio-educational activities and their cohesive links with families; all key elements in the development of urban agriculture. Thus, the main objective of this research is to develop a procedure, in compact cities, to assess the potential installation of rooftop greenhouses (RTGs) in schools. The generation of a dynamic assessment tool capable of identifying and prioritizing schools with a high potential for RTGs and their eventual implementation would also represent a significant factor in the environmental, social, and nutritional education of younger generations. The methodology has four-stages (Pre-selection criteria; Selection of necessities; Sustainability analysis; and Sensitivity analysis and selection of the best alternative) in which economic, environmental, social and governance aspects all are considered. It makes use of Multi-Attribute Utility Theory and Multi-Criteria Decision Making, through the Integrated Value Model for Sustainability Assessments and the participation of two panels of multidisciplinary specialists, for the preparation of a unified sustainability index that guarantees the objectivity of the selection process. This methodology has been applied and validated in a case study of 11 schools in Barcelona (Spain). The social perspective of the proposed methodology favored the school in the case-study with the most staff and the largest parent-teacher association (social and governance indicators) that obtained the highest sustainability index (S11); at a considerable distance (45%) from the worst case (S3) with fewer school staff and parental support. Finally, objective decisions may be taken with the assistance of this appropriate, adaptable, and reliable Multi-Criteria Decision-Making tool on the vertical integration and

  10. Self-Organization and the Bypass: Re-Imagining Institutions for More Sustainable Development in Agriculture and Food

    Directory of Open Access Journals (Sweden)

    Stephen Sherwood

    2016-12-01

    Full Text Available In exploring the social dynamics of agrofood movements in Ecuador as examples of self-organization (i.e., locally distributed and resolved development, this article departs from a preoccupation with innovation by means of design and the use of scaling as a metaphor for describing research contributions in agriculture and food. The case material highlights that much development is contingent, unpredictable, and unmanageable as well as unbound to fixed spaces or places. In their study of people’s daily practice, the authors do not find clear boundaries between dichotomies of internal–external, lay–expert, traditional–modern, or local–global organization, but heterogeneous blends of each. For the purposes of sustainable development, this highlights the need for attention to be paid to relationships (social, material, and biological, adaptation (the capacity to innovate, and responsibility (adherence to norms of sustainability. Far from romanticizing self-organization, the authors acknowledge that people and their institutions share varying degrees of complicity for the goods as well as the bads of their economic activity, such as mass soil degradation, agrobiodiversity loss, and poisoning by pesticides. Nevertheless, even under highly difficult conditions, certain actors effectively bypass the limitations of formal institutions in forging a socio-technical course of action (i.e., policy for relatively healthy living and being. As such, the authors have come to appreciate self-organization as a neglected, if paradoxical, resource for policy transition towards more sustainable agriculture and food.

  11. Improving productivity in agriculture. One of the five key areas to sustainable development where progress is possible with the resources and technologies at our disposal today

    International Nuclear Information System (INIS)

    2002-01-01

    Despite progress made since the 1996 World Food Summit that set the goal of halving the number of undernourished people by the 2015, serious food insecurity persists in many parts of the world. Although more food is being produced worldwide than ever before, some 800 million people are still chronically malnourished. Improving agricultural productivity is a driving force for both economic and social development. When agriculture falters, income sources are lost, social ties are disrupted, and, as a result, societies become more mobile. Up-to-date technologies, improved plant and animal stock, and better soil and water management practices not only combat food insecurity, they are also important to achieving sustainable agriculture practices essential to maintaining an appropriate balance between conservation and use of all the resources required to grow crops and raise livestock. Through its programme in Food and Agriculture operated with the Food and Agriculture Organization (FAO), the International Atomic Energy Agency (IAEA) works to enhance capacities at national and international levels for identifying and alleviating constraints to sustainable food security by facilitating development and adoption of nuclear and related biotechnologies. With an annual budget of nearly $10 million, this programme helps Member States to improve productivity in agriculture, particularly through better water and soil management practices, efficient crop nutrition, and control of insect pests

  12. Agricultural Water Use Sustainability Assessment in the Tarim River Basin under Climatic Risks

    2018-02-01

    Full Text Available Proper agricultural water management in arid regions is the key to tackling climatic risks. However, an effective assessment of the current response to climate change in agricultural water use is the precondition for a group adaptation strategy. The paper, taking the Tarim River basin (TRB as an example, aims to examine the agricultural water use sustainability of water resource increase caused by climatic variability. In order to describe the response result, groundwater change has been estimated based on the Gravity Recovery and Climate Experiment (GRACE and the Global Land Data Assimilation System (GLDAS–Noah land surface model (NOAH data. In order to better understand the relationship between water resource increase and agricultural water consumption, an agricultural water stress index has been established. Agricultural water stress has been in a severe state during the whole period, although it alleviated somewhat in the mid–late period. This paper illustrates that an increase in water supply could not satisfy agricultural production expansion. Thus, seasonal groundwater loss and a regional water shortage occurred. Particularly in 2008 and 2009, the sharp shortage of water supply in the Tarim River basin directly led to a serious groundwater drop by nearly 20 mm from the end of 2009 to early 2010. At the same time, a regional water shortage led to water scarcity for the whole basin, because the water consumption, which was mainly distributed around Source Rivers, resulted in break-off discharge in the mainstream. Therefore, current agricultural development in the Tarim River basin is unsustainable in the context of water supply under climatic risks. Under the control of irrigation, spatial and temporal water allocation optimization is the key to the sustainable management of the basin.

Agriculture is faced with a lot of uncertainly most of which are not within the control of farmers. Global climatic change, climatic disasters, fluctuation of global economic and competitiveness of multinational company make difficulties of farmers to pursue his sustainable farming activity. The challenge and the role of government is to reduce uncertainly and to improve resiliency of the small farmer. Agriculture insurance shall focus on risk factors that are difficult to manage or cannot be managed by small farmers and it is should be viewed as just one aspect of the “holistic” risk management strategy. Technology, market, consumer, behaviour, development will always move forward, and no individual farmers can adapt this change alone, so small farmers need to corporate with each other that can optimized the resources they have. Cooperative could create possibilities, value added, shortening the supplied chain, made a product more effective and efficient, and finally can complete in domestic and global markets. Therefore, agriculture insurance as well a farmer cooperative may play an important role on sustainability of rice production in Indonesia. Nowadays and in the future agriculture sustainability is a not merely of technology problems but also a matter of economic-social-culture and politic issues within local, national, and international context.

    Full Text Available The adoption of sustainable technologies, like Agriculture Conservation Practices in drought-stricken suburban areas is a must for land sustainable management. In order to contribute with the inclusion of this technology at the Ignacio Agramonte CCS, in El Carmen, municipality of Nuevitas, Camaguey, Agricultural Extension tools were used, like systemic diagnostic and participatory orientation. The SWOT matrix was created after three workshops, where agricultural conservation practices were identified for adoption, based on actual conditions at the CCS. As a result, five key problems were identified: lack of water for irrigation, saline waters, saline soils, use of inappropriate management technologies, deforestation and poor training in agriculture. The most critical impact found in the matrix was in Weaknesses - Threats (81.3%. Furthermore, local farmers, inhabitants and public officials agreed on the use of agricultural extension tools to provide positive elements and an effective way to help increase motivation and knowledge about agricultural conservation technology, as an alternative to mitigate the degradation state of lands at the CCS.

    Full Text Available Ending hunger, achieving food security and promoting sustainable development are at the top of the list of United Nations sustainable global development priorities after 2015. In addition to many positive effects, efforts of mankind regarding the reduction of rural poverty realized through the Green Revolution have had many negative effects, primarily related to natural resources. Irreversible devastation of land, air and water quality deterioration and jeopardizing biodiversity have been recognized as key elements of unsustainability of existing agricultural development concept. Consequently, there is a need for the adoption of a new concept of agricultural development, which will lie between intensive conventional and organic farming. The concept which has already been applied in some regions of the world and whose basic goal is to find a way to increase production with a negligible negative impact on the environment is sustainable agricultural intensification. The aim of this paper is to look at both positive and negative aspects of biotechnology development so far and point out the place and role the sustainable intensification concept should have in relation to conservation of natural resources and achievement of food security.

    Full Text Available Traditional agriculture in rainfed uplands of India has been experiencing low agricultural productivity as the lands suffer from poor soil fertility, susceptibility to water erosion and other external pressures of development and climate change. A shift towards more sustainable cropping systems such as conservation agriculture production systems (CAPS may help in maintaining soil quality as well as improving crop production and farmer’s net economic benefit. This research assessed the effects over three years (2011-2014 of reduced tillage, intercropping, and cover cropping practices customized for maize-based production systems in upland areas of Odisha, India. The study focused on crop yield, system productivity and profitability through maize equivalent yield and dominance analysis. Results showed that maize grain yield did not differ significantly over time or among CAPS treatments while cowpea yield was considered as an additional yield in intercropping systems. Mustard and horsegram grown in plots after maize cowpea intercropping recorded higher grain yields of 25 and 37%, respectively, as compared to those without intercropping. Overall, the full CAPS implementation i.e. minimum tillage, maize-cowpea intercropping and mustard residue retention had significantly higher system productivity and net benefits than traditional farmer practices, i.e. conventional tillage, sole maize cropping, and no mustard residue retention. The dominance analysis demonstrated increasing benefits of combining conservation practices that exceeded thresholds for farmer adoption. Given the use of familiar crops and technologies and the magnitude of yield and income improvements, these types of CAPS should be acceptable and attractive for smallholder farmers in the area. This in turn should support a move toward sustainable intensification of crop production to meet future household income and nutritional needs.

    2016-10-01

    Full Text Available In industrialized nations, local food networks have generally been analyzed through alternative food systems, in spite of the fact that they are much more diverse than this would imply. In France, ‘short food chains’ are both a continuation of a long tradition and a recent trend which now extends beyond activists, to consumers and producers as well. This paper will explore the conditions under which these chains can change the practices and knowledge of ordinary actors in urban food systems, from producers to urban consumers and policy-makers, in the area of agriculture and sustainability. It will consider the case study of the creation and development of an urban open-air market which has been analyzed using intervention research with input from economic sociology. We will highlight how personal relations, which are encouraged by a participatory context, support the evolution of practices and knowledge. We will also illustrate how a system of produce labelling has emerged as a mediation resource, and has increased changes as well as participation within the re-territorialization of the urban food system. By describing a concrete expression of food democracy which is spreading in France via a free collective trademark, and by showing its role in the transition of ‘ordinary’ actors towards a more sustainable agriculture, this paper will shine new light onto local food chains as well as traditional short food chains, and will call for more research on the subject.

    The problem of sustainability is a topic that since the end of the XX century has been worrying more the different sectors of society; becoming one of the topics of greatest interest for managers, consumers, academics and investigators that conform the different agricultural food chains of the world. This paper presents from the general systems theory point of view some elements of critical reflection, approaching the problem of sustainability from the complexity of agricultural production systems, beginning with the original philosophical conception of agricultural and ending by outlining some considerations that should be kept in mind for the development of scientific and technological advances concordant with the agricultural food chain needs of the XX century; which permit an orientation of not only work by profession is who lead the processes of animal and vegetable production, but also creates a sense of pertinence in all of the participants in the chain, highlighting the importance of studying by means of systemic thought, agronomy and animal science, as disciplines that approach to complexities of agriculture which is the angular stone of civilization, such as we know it at the moment

    Jordan is one of the world's most water-deficit countries with only about 4% of the total land area considered arable. As a consequence agricultural production is greatly constrained by limited natural resources. Therefore, a major challenge for the country is to promote the sustainable use of natural resources for agricultural purposes. This challenge is being made harder by the ongoing processes of degradation due to increased population pressure, which undermine any social and economic development gains. In the southern plains of Jordan, sustainability of farming practices has worsened in the past three decades, exacerbating pressure on land and increasing land degradation processes. Non-sustainable land use practices include improper ploughing, inappropriate rotations, inadequate or inexistent management of plant residues, overgrazing of natural vegetation, random urbanization, land fragmentation and over-pumping of groundwater. The root cause is the high population growth which exerts excessive pressure on the natural resources to meet increased food and income demand. The poorest farmers who are increasingly growing cereals on marginal areas. Wheat and barley are now grown with little to no rotation, with no nutrient replenishment, and at places avoiding even fallow. Small landholding sizes and topographic features of the area tend to oblige longitudinal mechanized tillage operations along the slopes. Overall, the constraints facing the deprived land users such as, poor access to technology, capital and organization are the factors that lead into unsustainable practices. The main bottlenecks and barriers that hinder mainstreaming of sustainable land management in Jordan can be grouped into three main categories: (i) Knowledge, (ii) Institutional and Governance, and (iii) Economic and Financial. In this case study, the key challenge was to create a knowledge base among local stakeholders - including planners, extension officers, NGO/community leaders, teachers

    The ability of the earth to sustain health among humans and in the natural world is under threat from overpopulation, environmental degradation, and climate change. These global threats are anticipated to harm health and human occupation in many direct and indirect ways. Strategies are needed to mitigate the effects of these threats and to build individual and community capacities to foster resilience. This paper links issues of sustainability with occupational therapy philosophy and discusses how employing a sustainability lens with professional reasoning can help practitioners integrate sustainability into their practice. Human occupation is inseparable from the environments in which people live. Human occupation has caused the current environmental crisis, and targeted human action is required to safeguard future health and well-being. Occupational therapists have an ethical obligation to use professional reasoning strategies that, taken collectively, can help to build a sustainable and resilient future.

    This review addresses the perspectives of Azolla as a multifaceted aquatic resource to ensure ecosystem sustainability. Nitrogen fixing potential of cyanobacterial symbiont varies between 30 and 60 kg N ha(-1) which designates Azolla as an important biological N source for agriculture and animal industry. Azolla exhibits high bioremediation potential for Cd, Cr, Cu, and Zn. Azolla mitigates greenhouse gas emission from agriculture. In flooded rice ecosystem, Azolla dual cropping decreased CH4 emission by 40 % than did urea alone and also stimulated CH4 oxidation. This review highlighted integrated approach using Azolla that offers enormous public health, environmental, and cost benefits.

    Full Text Available This article argues that it is possible to transform innovation pathways in natural-resource-based industries towards more sustainable ones. In particular, it employs the socio-technical transitions framework to understand the structural barriers that the industrial agricultural system puts to COOPSOL, an Argentinean cooperative project of organic apiculture. The article is based on qualitative data that systematize, on the one hand, the pressures for continuity and change in the agricultural system. On the other hand, the data reveal the main perceptions of COOPSOL´s actors about the existing structural limits.

    2017-02-01

    Full Text Available This article aims to assess the impacts of climate change towards the achievement of Sustainable Development Goal number two (SDG 2 as well as examining the poverty alleviation strategies by subsistence farmers in South Africa. Widespread hunger and poverty continue to be among the most life-threatening problems confronting mankind. Available statistics show that global poverty remains a serious challenge around the world. Across the globe, one in five people lives on less than $1 a day and one in seven suffers from chronic hunger. Similarly, the developing world is adversely affected by poverty and hunger. In the sub-Saharan Africa, research has revealed a higher prevalence of hunger, malnutrition, poverty and food insecurity. SDG 2 focuses more on eliminating hunger and promoting sustainable agriculture. The study employed an exploratory design and a qualitative method. Snowball sampling was used in selecting relevant sources which led the researchers to other research work on the same field through keywords and reference lists. The researchers employed discourse analysis to analyse data. The study discovered that there are numerous potential effects climate change could have on agriculture. It affects crop growth and quality and livestock health. Farming practices could also be affected as well as animals that could be raised in particular climatic areas. The impact of climate change as well as the susceptibility of poor communities is very immense. The article concludes that climate change reduces access to drinking water, negatively affects the health of people and poses a serious threat to food security.

    2013-07-01

    Full Text Available Increasing concerns about global environmental change and food security have focused attention on the need for environmentally sustainable agriculture. This is agriculture that makes efficient use of natural resources and does not degrade the environmental systems that underpin it, or deplete natural capital stocks. We convened a group of 29 ‘practitioners’ and 17 environmental scientists with direct involvement or expertise in the environmental sustainability of agriculture. The practitioners included representatives from UK industry, non-government organizations and government agencies. We collaboratively developed a long list of 264 knowledge needs to help enhance the environmental sustainability of agriculture within the UK or for the UK market. We refined and selected the most important knowledge needs through a three-stage process of voting, discussion and scoring. Scientists and practitioners identified similar priorities. We present the 26 highest priority knowledge needs. Many of them demand integration of knowledge from different disciplines to inform policy and practice. The top five are about sustainability of livestock feed, trade-offs between ecosystem services at farm or landscape scale, phosphorus recycling and metrics to measure sustainability. The outcomes will be used to guide on-going knowledge exchange work, future science policy and funding.

  14. How the organic food system supports sustainable diets and translates these into practice

    Directory of Open Access Journals (Sweden)

    Carola eStrassner

    2015-06-01

    Full Text Available Organic production and consumption provide a delineated food system that can be explored for its potential contribution to sustainable diets. While organic agriculture improves the sustainability performance on the production side, critical reflections are made on how organic consumption patterns, understood as the practice of people consuming significant amounts of organic produce, may also be taken as an example for sustainable food consumption. The consumption patterns of regular organic consumers seem to be close to the sustainable diet concept of FAO. Certain organic-related measures might therefore be useful in the sustainability assessment of diets, e.g. organic production and organic consumption. Since diets play a central role in shaping food systems and food systems shape diets, the role of organic consumption emerges as an essential topic to be addressed. This role may be based on four important organic achievements: organic agriculture and food production has a definition, well-established principles, public standards and useful metrics. By 2015 data for organic production and consumption is recorded annually from more than 160 countries, and regulations are in force in more than 80 countries or regions. The organic fo

    2018-03-01

    Full Text Available Sustainable development has become the main focus of the global development agenda as presented in the 2015 Sustainable Development Goals (SDGs. However, for countries to assess progress, they need to have reliable baseline indicators. Therefore, the objective of this paper is to develop a composite baseline index of the agriculture-related SDGs in Southern Africa to guide progress reporting. The paper identified eight of the SDG indicators related to the agriculture sector. The paper relies on data for indicators from five SDGs (SDGs 1, 2, 6, 7 and 15. Applying the arithmetic mean method of aggregation, an agriculture-related SDG composite index for Southern Africa between zero (0 = poor performance and 100 (best possible performance was computed for thirteen countries that had data on all identified indicators. The results show that the best performing countries (Botswana, Angola, Namibia, Zambia and South Africa in the assessment recorded high scores in SDGs 1, 2 and 7. The three countries (Democratic Republic of Congo, Zimbabwe and Madagascar that performed poorly on both SDG 1 and 2 also had the least scores on the overall agriculture-related SDG composite index. The water stress indicator for SDG 6 recorded the worst performance among most countries in the region. Possible approaches to improve the contribution of agriculture to SDGs may include investing more resources in priority areas for each agriculture-related SDG depending on baseline country conditions. The implementation, monitoring and evaluation of regional and continental commitments in the agriculture sector and the SDGs are critical for achievement of the targets at the national and local levels. While the methods employed are well-grounded in literature, data unavailability for some of the SDGs in some countries presented a limitation to the study, and future efforts should focus on collecting data for the other SDGs in order to permit a wider application.

    Agriculture is currently facing unprecedented challenges: ensuring food, fiber and energy production in the face of global change, maintaining the economic performance of farmers and preserving natural resources such as biodiversity and associated key ecosystem services for sustainable agriculture. Addressing these challenges requires innovative landscape scale farming systems that account for changing economic and environmental targets. These novel agricultural systems need to be recognized, accepted and promoted by all stakeholders, including local residents, and supported by public policies. Agroecosystems should be considered as socio-ecological systems and alternative farming systems should be based on ecological principles while taking societal needs into account. This requires an in-depth knowledge of the multiple interactions between sociological and ecological dynamics. Long Term Socio-Ecological Research platforms (LTSER) are ideal for acquiring this knowledge as they (i) are not constrained by traditional disciplinary boundaries, (ii) operate at a large spatial scale involving all stakeholders, and (iii) use systemic approaches to investigate biodiversity and ecosystem services. This study presents the socio-ecological research strategy from the LTSER "Zone Atelier Plaine & Val de Sèvre" (ZA PVS), a large study area where data has been sampled since 1994. Its global aim is to identify effective solutions for agricultural development and the conservation of biodiversity in farmlands. Three main objectives are targeted by the ZAPVS. The first objective is intensive monitoring of landscape features, the main taxa present and agricultural practices. The second objective is the experimental investigation, in real fields with local farmers, of important ecosystem functions and services, in relation to pesticide use, crop production and farming socio-economic value. The third aim is to involve stakeholders through participatory research, citizen science and

    The water requirement greatly increased due to population growth, increased agricultural areas and industrial development, thus causing high water demand. The complex problems facing by country is water pricing is not designed optimally as a staple of human needs and on the other hand also cannot guarantee the maintenance and distribution of water effectively. The cheap water pricing caused increase of water use and unmanageable water resource. Therefore, the more optimal water pricing as an effective control of water policy is needed for the sake of ensuring water resources conservation and sustainability. This paper presents the review on problems, issues and mathematical modelling of water pricing based on agriculture and domestic groundwater for water sustainability and conservation.

    Full Text Available The need to strengthen the connection between academia and society has received increased attention over the past years. The importance of bringing university students closer to stakeholders in society as part of their learning process is high regarding sustainable agriculture, because of its applied approach. University programs based on experiential and action-oriented learning have been developed over the past decades, but more knowledge is needed about the impact of these educational activities. In a short course in sustainable agriculture at the University of Gastronomic Sciences in Bra, Italy, we examined the impacts of experiential and action-oriented learning on competency development as well as transformational impacts on the students. We found that students improve on several core competences as a result of their participation in the short course, and also signs of deep transformational processes among the students.

    Agricultural practices have proven to be unsuitable in many cases, causing considerable reductions in soil quality. Land management practices can provide solutions to this problem and contribute to get a sustainable agriculture model. The main objective of this work was to assess the effect of different agricultural management practices on soil microbial community structure (evaluated as abundance of phospholipid fatty acids, PLFA). Five different treatments were selected, based on the most common practices used by farmers in the study area (eastern Spain): residual herbicides, tillage, tillage with oats and oats straw mulching; these agricultural practices were evaluated against an abandoned land after farming and an adjacent long term wild forest coverage. The results showed a substantial level of differentiation in the microbial community structure, in terms of management practices, which was highly associated with soil organic matter content. Addition of oats straw led to a microbial community structure closer to wild forest coverage soil, associated with increases in organic carbon, microbial biomass and fungal abundances. The microbial community composition of the abandoned agricultural soil was characterised by increases in both fungal abundances and the metabolic quotient (soil respiration per unit of microbial biomass), suggesting an increase in the stability of organic carbon. The ratio of bacteria:fungi was higher in wild forest coverage and land abandoned systems, as well as in the soil treated with oat straw. The most intensively managed soils showed higher abundances of bacteria and actinobacteria. Thus, the application of organic matter, such as oats straw, appears to be a sustainable management practice that enhances organic carbon, microbial biomass and activity and fungal abundances, thereby changing the microbial community structure to one more similar to those observed in soils under wild forest coverage.

  1. Nested archetypes of vulnerability in African drylands: where lies potential for sustainable agricultural intensification?

    Food production is key to achieving food security in the drylands of sub-Saharan Africa. Since agricultural productivity is limited, however, due to inherent agro-ecological constraints and land degradation, sustainable agricultural intensification has been widely discussed as an opportunity for improving food security and reducing vulnerability. Yet vulnerability determinants are distributed heterogeneously in the drylands of sub-Saharan Africa and sustainable intensification cannot be achieved everywhere in cost-effective and efficient ways. To better understand the heterogeneity of farming systems’ vulnerability in order to support decision making at regional scales, we present archetypes, i.e. socio-ecological patterns, of farming systems’ vulnerability in the drylands of sub-Saharan Africa and reveal their nestedness. We quantitatively indicated the most relevant farming systems’ properties at a sub-national resolution. These factors included water availability, agro-ecological potential, erosion sensitivity, population pressure, urbanisation, remoteness, governance, income and undernourishment. Cluster analysis revealed eight broad archetypes of vulnerability across all drylands of sub-Saharan Africa. The broad archetype representing better governance and highest remoteness in extremely dry and resource-constrained regions encompassed the largest area share (19%), mainly indicated in western Africa. Moreover, six nested archetypes were identified within those regions with better agropotential and prevalent agricultural livelihoods. Among these patterns, the nested archetype depicting regions with highest erosion sensitivity, severe undernourishment and lower agropotential represented the largest population (30%) and area (28%) share, mainly found in the Sahel region. The nested archetype indicating medium undernourishment, better governance and lowest erosion sensitivity showed particular potential for sustainable agricultural intensification, mainly in

    One of the main environmental effects of agriculture is the negative impacts on areas with soil vulnerability to compaction and undersurface water derived from inputs and treatment distributions. A solution may represented from the "Precision Farming". Precision Farming refers to a management concept focusing on (near-real time) observation, measurement and responses to inter- and intra-variability in crops, fields and animals. Potential benefits may include increasing crop yields and animal performance, cost and labour reduction and optimisation of process inputs, all of which would increase profitability. At the same time, Precision Farming should increase work safety and reduce the environmental impacts of agriculture and farming practices, thus contributing to the sustainability of agricultural production. The concept has been made possible by the rapid development of ICT-based sensor technologies and procedures along with dedicated software that, in the case of arable farming, provides the link between spatially-distributed variables and appropriate farming practices such as tillage, seeding, fertilisation, herbicide and pesticide application, and harvesting. Much progress has been made in terms of technical solutions, but major steps are still required for the introduction of this approach over the common agricultural practices. There are currently a large number of sensors capable of collecting data for various applications (e.g. Index of vegetation vigor, soil moisture, Digital Elevation Models, meteorology, etc.). The resulting large volumes of data need to be standardised, processed and integrated using metadata analysis of spatial information, to generate useful input for decision-support systems. In this context, a user-friendly IT applications has been developed, for organizing and processing large volumes of data from different types of remote sensing and meteorological sensors, and for integrating these data into user-friendly farm management support

    Agricultural practices pose threats to biotic diversity in freshwater systems with increasing use of glyphosate-based herbicides for weed control and animal waste for soil amendment becoming common in many regions. Over the past two decades, these particular agricultural trends have corresponded with marked declines in populations of fish and mussel species in the Upper Conasauga River watershed in Georgia/Tennessee, USA. To investigate the potential role of agriculture in the population declines, surface waters and sediments throughout the basin were tested for toxicity and analyzed for glyphosate, metals, nutrients, and steroid hormones. Assessments of chronic toxicity with Ceriodaphnia dubia and Hyalella azteca indicated that few water or sediment samples were harmful and metal concentrations were generally below impairment levels. Glyphosate was not observed in surface waters, although its primary degradation product, aminomethyl phosphonic acid (AMPA), was detected in 77% of the samples (mean = 509 μg/L, n = 99) and one or both compounds were measured in most sediment samples. Waterborne AMPA concentrations supported an inference that surfactants associated with glyphosate may be present at levels sufficient to affect early life stages of mussels. Nutrient enrichment of surface waters was widespread with nitrate (mean = 0.7 mg NO3-N/L, n = 179) and phosphorus (mean = 275 μg/L, n = 179) exceeding levels associated with eutrophication. Hormone concentrations in sediments were often above those shown to cause endocrine disruption in fish and appear to reflect the widespread application of poultry litter and manure. Observed species declines may be at least partially due to hormones, although excess nutrients and herbicide surfactants may also be implicated.

    Regarding increasing pressures by global societal and climate change, for example, the assessment of the impact of land use and land management practices on land productivity, land degradation and the related decrease in sustainable food production and the provision of ecosystem services gains increasing interest. Regarding international research on land use and soil threats, main problems in agricultural land use on global scale are erosion by water and wind, soil organic matter loss, salinization, depletion of nutrients, chemical and physical deterioration, including e.g. soil compaction. When coming to soil sciences, basically soil functions are affected negatively by intensive food production and field traffic. Management based negative changes in soil functions and a suboptimal soil structure have multiple negative effects on physical, biological and chemical soil functions, like a poor water balance, air and water permeability, disturbed soil fauna, impeded root penetration etc. and in consequence on the achievable yields. The presentation deals with the multiple effects of different agricultural machinery and technologies and different agricultural soil tillage (e.g. no-till, conservation tillage, ploughing), on various soil properties of a stagnic Luvisol in Lower Saxony, Germany. These are e.g. bulk density, air capacity, saturated water permeability, changes in pore size distribution and water retention curve as well as crop yields. Furthermore results of a long term study of bulk density and total pore size on more then 20 farms in Lower Saxony since the year 1952 will be presented. Finally, key factors and first recommendations for sustainable agricultural soil protection will be derived from the results.

    Full Text Available Abstract Introduction Sustainable agricultural development is an important goal in economic planning and human development worldwide. A range of processes and relationships are transformed, beginning with aspects of basic soil structure, organic matter content, and diversity and activity of soil biota. Eventually, major changes also occur in the relationships among weed, insect, and disease populations, and in the balance between beneficial and pest organisms. Ultimately, nutrient dynamics and cycling, energy use efficiency, and overall system productivity are impacted. Measuring and monitoring these changes during the conversion period helps the farmer evaluate the success of the conversion process, and provides a framework to determine the requirements for sustainability. After improving resource use efficiency, replacement of ecological inputs with chemical inputs as second step and redesign of agro-ecosystems is as final step in transition of common to sustainable agriculture. The study was investigated to evaluation of Iran’s agricultural systems status. Materials and Methods Using organic and ecological inputs than chemicals is the second step for transition to sustainable agriculture. This study was performed to assess and measure the status of inputs replacement and agro-ecosystem designing based on ecological principle in Iran. For this purpose, we used 223 studied researches on agronomical and medicinal plants. After, they analyzed based on functional and structural characteristics and then used. Considering to the importance of multi-functionality in sustainable agriculture, in this study we considered the multiple managements for inputs replacement. The using functions in the study were: improving fertility and bio-chemical characteristics of soil, ecological managements of pest and diseases, reducing the energy usage, and increasing biodiversity. Using the organic and biological inputs, remaining the plant residual on soil, using

    Full Text Available With the emergence of environmental protection as a global issue, implementing environmental practices for sustaining green supply chain management (GSCM has received a lot of attention. This study investigates the impact of integration with suppliers and supply disruption risk on environmental practices. It also examines the role of supplier integration and supply disruption risk on performance. Finally, it investigates the relationship between environmental practices and performance in order to sustain green supply chains. Based on 272 survey responses from supply and purchase managers, our research results support the positive impact of integration with suppliers and the negative impact of supply disruption risk on the adoption of environmental practices. Furthermore, they provide empirical evidence that environmental practices and integration with suppliers are positively associated with performance, while supply disruption risk is negatively associated with performance. This study identifies antecedents and establishes a research framework of GSCM. More importantly, it provides meaningful insights to managers regarding the implementation of environmental practices related to other supply chain practices for sustaining green supply chains.

    According to the FAO's latest estimates, the world food supply can only be guaranteed if the 1982 agricultural production is increased by approx. 50% by the year 2000. 2/3 of this production increase must be achieved on areas already under cultivation. This means that in addition to balanced mineral fertilization the use of pesticides will have to be intensively continued in order to fully exploit the improved yield potential of the cultivated plants achieved by breeding. The primary research objective is therefore to extend our knowledge of the uptake and effects of pesticides in the plant as well as their persistence in agricultural ecosystems in order to be able to apply them both more efficiently and more safely. The Institute of Radioagronomy at the Kernforschungsanlage Juelich GmbH (Juelich Nuclear Research Centre) is carrying out practical experiments into these problems using 14 C-labelled pesticides under field conditions. In this way statements will become possible on the uptake and residue situation in plants, translocation and metabolism in the soil, the balance in the year of application as well as on the uptake of untreated cultures in the crop rotation. Parallel to this, uptake after leaf spraying or after seed grain treatment is being studied under standardized conditions, as well as for example the mineralization, sorption and fixation of active substances and metabolites in the soil. Results from the past 12 years are being utilized as a basis for an evaluation of the state of knowledge. (orig.)

    The concept of sustainable agriculture encompasses ecological, economic and social problems in which weather and climate can be of great importance. Despite considerable technological advancement and improved irrigation facilities, Indian farmers are still dependent on seasonal rains, which are highly variable both in time and space. Inclement weather events like droughts, floods, cold and heat waves, hails, squalls, tropical storms severely affect the agricultural production. Their harmful effects may be partially reduced if the occurrence of these events is predicted in advance and farmers are suitably advised to take preventive/corrective measures. With the objective to help the farmers maximize profits by decreasing weather related losses, increasing the timeliness of farm operations and to reduce environmental pollution through the optimal use of agricultural chemicals, the location specific/regional Agrometeorological Advisory Service was initiated in the year 1991. The forecasting skills of most of the weather parameters at Hisar have improved considerably over the years. Now, it is time to integrate and make use of vast agrometeorological information available online in preparing weather based advisories for in-season agricultural operations both for single locations and on a meso or regional scale as desired. This can be further strengthened through input from new technologies such as neural network, remote sensing, GIS, ground measurements and modeling applications along with traditional wisdom available with the farming communities should be integrated to further strengthen the location specific weather forecasting system for the development of sustainable and more efficient crop production systems.

    Elizabeth T. Alori

    2017-06-01

    Full Text Available The use of excess conventional Phosphorus (P fertilizers to improve agricultural productivity, in order to meet constantly increasing global food demand, potentially causes surface and ground water pollution, waterway eutrophication, soil fertility depletion, and accumulation of toxic elements such as high concentration of selenium (Se, arsenic (As in the soil. Quite a number of soil microorganisms are capable of solubilizing/mineralizing insoluble soil phosphate to release soluble P and making it available to plants. These microorganisms improve the growth and yield of a wide variety of crops. Thus, inoculating seeds/crops/soil with Phosphate Solubilizing Microorganisms (PSM is a promising strategy to improve world food production without causing any environmental hazard. Despite their great significance in soil fertility improvement, phosphorus-solubilizing microorganisms have yet to replace conventional chemical fertilizers in commercial agriculture. A better understanding of recent developments in PSM functional diversity, colonizing ability, mode of actions and judicious application should facilitate their use as reliable components of sustainable agricultural systems. In this review, we discussed various soil microorganisms that have the ability to solubilize phosphorus and hence have the potential to be used as bio fertilizers. The mechanisms of inorganic phosphate solubilization by PSM and the mechanisms of organic phosphorus mineralization are highlighted together with some factors that determine the success of this technology. Finally we provide some indications that the use of PSM will promote sustainable agriculture and conclude that this technology is ready for commercial exploitation in various regions worldwide.

    Full Text Available Organizational sustainability (OS has been guiding the decision-making process of managers in order to generate competitive advantage. This paper aims to identify the sustainable practices performed by large corporations in the implementation of OS. Reports with actions performed by large organizations and their reach in the three pillars of sustainability—environmental, economic, and social dimensions—are disclosed to their main stakeholders, based on short, medium and long-term sustainable goals. These reports often reflect the progress of OS or the progress made toward them. However, few studies investigate the sustainable practices adopted by firms and their reproducibility. A search was performed in reports selected from the firms listed by the Corporate Sustainability Index (CSI from 2012–2016, belonging to the Brazilian stock market in services sector of the economy and employed the Global Reporting Initiative (GRI methodology. The results showed the strategic planning involving infrastructure, environment, human resources, product innovation, organizational management and deadline setting acted as the baseline for the implementation of the practices found. The findings will guide the managers´ decisions in the development of their strategic planning, based on practical and objective results.

    Full Text Available In the present article was carried out a descriptive statistical study in which different tools like non structured interviews, revision of files and the use of the SIG are integrated. The investigation was developed in 2010 - 2011. The population of Banao showed a high sense of ownership to the area and 70% is in labour age highlighting the range of 25 - 39 years, out of them 24,1% of the producers have been devoted to the agriculture for 10 and 20 years. 45,8% presents problems with the supply source, 71,8% should drive the water to more than 200 m to water. When analyzing the degradation of the soil it is appreciated that 97% of the soil that is dedicated to the cultivation of the onion is eroded, existing areas where the cultivation should not be fomented, for the excessive exploitation of its soils. Among the interviewed producers 59.7% knows that there is degradation of the soils in its property, however 51.7% doesn't apply any alternative of protection of the soil. The current production of onion compromises the stability of the ecosystem considerably. This study constitutes an indispensable premise to advance toward a sustainable model of the local onion system.

    In the 450,000 acres of the Everglades Agricultural Area (EAA) of South Florida, farming practices have long been mindful of phosphorus (P) management as it relates to sufficiency and efficiency of P utilization. Over two decades of P best management practices have resulted in 3001 metric-ton of P load reduction from the EAA to downstream ecosystems. During the summer, more than 50,000 acres of fallow sugarcane land is available for rice production. The net value of growing flooded rice in the EAA as a rotational crop with sugarcane far exceeds its monetary return. Soil conservation, improvement in tilth and P load reduction are only some of the benefits. With no P fertilizer applied, a two-year field trial on flooded rice showed improved outflow P concentrations by up to 40% as a result of particulate setting and plant P uptake. Harvested whole grain rice can effectively remove a significant amount of P from a rice field per growing season. In parts of the EAA where soils are sandy, the application of using locally derived organic amendments as potential P fertilizer has gained interest over the past few years. The use of local agricultural and urban organic residues as amendments in sandy soils of South Florida provide options to enhance soil properties and improve sugarcane yields, while reducing waste and harmful effects of agricultural production on the environment. A lysimeter study conducted to determine the effect of mill ash and three types of biochar (rice hulls, yard waste, horse bedding) on sugarcane yields, soil properties, and drainage water quality in sandy soils showed that mill ash and rice hull biochar increased soil TP, Mehlich 3-P (M3-P), and cation exchange capacity (CEC) compared to the control. TP and M3-P content remained constant after 9 months, CEC showed a significant increase over time with rich hull biochar addition. Future projects include the utilization of aquatic vegetation, such as chara and southern naiad as bio-filters in farm

    Between 1994 and 1996 CLM developed a method for assessing the ecological and economic sustainability of producing and using energy from agricultural and forest biomass. The method has much in common with environmental life cycle assessment (LCA). CLM has also co-ordinated a concerted action called 'Environmental aspects of biomass production and routes for European energy supply'. LCA is at present the best available instrument for assessing the ecological sustainability of energy crops. CLM focused on three topics disseminating the results of the concerted action; updating the work on bioethanol, and proposals for new financial instruments. The results are presented in this report. First, the results from the concerted action and work carried out by CLM were disseminated. Papers were presented at the international conference on 'Implementation of solid biofuels for carbon dioxide mitigation', 29-30 September 1997, Uppsala, Sweden, and at the international workshop on 'Environmental aspects of energy crop production', 9-10 October 1997, Brasimone, Italy. In addition, a paper was written on the need to co-ordinate policy options to stimulate the production and use of energy crops from an energy, agricultural and environmental point of view. Second, a study on bioethanol was carried out in which data obtained elsewhere on the use of bioethanol as a transport fuel were revised and updated. The sustainability of bioethanol production from sugar beet was compared with that of bioethanol from winter wheat. Using bioethanol from sugar beet replaces more fossil energy than bioethanol from winter wheat. For both crops, the costs per ton avoided CO2 decrease over time to 2010, but are still higher than electricity routes. The third action was the development of proposals for new financial instruments to stimulate energy production from biomass in the agricultural and forestry sector. This proposal was presented at the ALTENER Seminar on 'Financial incentives for

    Strategically leveraging health and safety initiatives with sustainability and stewardship helps organizations improve profitability and positively impact team member and customer attachment to the organization. Collective efficacy enhances the triple bottom line: healthy people, healthy planet, and healthy profits. The HS(3)™ Best Practice Exchanges group demonstrated that collective efficacy can leverage the social cohesion, communication channels, and activities within workplaces to promote a healthy, sustainable work culture. This in turn (1) protects the health and safety of workers, (2) preserves the natural environment, and (3) increases attachment to the organization. Community-based participatory research using the Attach21 survey assessed the progress of these companies in their efforts to integrate health, safety, sustainability, and stewardship. Monthly Best Practice Exchanges promoted collective efficacy by providing support, encouragement, and motivation to share and adopt new ideas. Copyright 2013, SLACK Incorporated.

    The study aimed to explore the knowledge, attitudes, and practices of women farmers working in tobacco production concerning the social, environmental, and health impacts of this economic activity. Focus groups were used in this qualitative study, and themes were explored until reaching saturation. The study was conducted in a municipality (county) in southern Brazil in 2013 and included 64 women farmers. The discussions revealed participants' familiarity with health problems associated with workloads in tobacco production: green tobacco sickness, pesticide poisoning, musculoskeletal disorders, and others. The discussions also revealed a concern with the negative impacts of tobacco agriculture on the environment. They also revealed apprehension concerning decisions on switching to alternatives for sustainable agricultural production, emphasizing that on-going and systematic government support would be necessary for such a transition. Women farmers identified various factors that contribute to the persistence of tobacco farming: small holdings for cultivation, lack of guarantees for marketing crops, and indebtedness to tobacco companies. The study showed that an integrated approach is needed to deal with tobacco farmers' problems, considering a balance between farmers' beliefs and government decisions. This approach, in keeping with the recommendations of the WHO Framework Convention on Tobacco Control, may help strengthen policies and measures to promote health and sustainable local development.

    Soil erosion can lead to severe destruction of agricultural sustainability that affects not only productivity, but the entire ecosystem in the neighboring areas. Sediments transported together with the associated nutrients and chemicals can significantly impact downstream water bodies. Various conservation and management practices implemented individually or integrated together as a system can be used to reduce the negative impacts on agricultural watersheds from soil erosion. Hydrological models are useful tools for decision makers when selecting the most effective combination of management practices to reduce pollutant loads within a watershed system. The Annualized Agricultural Non-point Source (AnnAGNPS) pollutant loading management model can be used to analyze the effectiveness of diverse management and conservation practices that can control or reduce the impact of soil erosion processes and subsequent sediment loads in agricultural watersheds. A 506 km2 Mediterranean medium-size watershed (Carapelle) located in Apulia, Southern Italy was used as a case study to evaluate the model and best management practices (BMPs) for sediment load control. A monitoring station located at the Ordona bridge has been instrumented to continuously monitor stream flow and suspended sediment loads. The station has been equipped with an ultrasound stage meter and a stage recorder to monitor stream flow. An infrared optic probe was used to measure suspended sediment concentrations (Gentile et al., 2010 ). The model was calibrated and validated in the Carapelle watershed on an event basis (Bisantino et al., 2013), and the validated model was used to evaluate the effectiveness of BMPs on sediment reduction. Various management practices were investigated including evaluating the impact on sediment load of: (1) converting all cropland areas into forest and grass covered conditions; (2) converting the highest eroding cropland areas to forest or grass covered conditions; and (3

    The Lower Mississippi River Alluvial Plain is a highly productive agricultural region for rice, soy beans, and cotton that depends heavily on irrigation. Development of the Mississippi River Alluvial Aquifer (MRAA), one of the more prolific agricultural aquifers in the country, has traditionally been the primary source for irrigation in the region yielding over 1,100 Mgal/day to irrigation wells. Increasingly, the realities of changing climate and rapidly declining water tables have highlighted the necessity for new water management practices. Tail-water recovery and reuse is a rapidly expanding practice due in part to the efforts and cost-sharing of the NRCS, but regional studies of the potential for such practices to alleviate groundwater mining under current and future climate are lacking. While regional studies of aquifer geology have long been available, including assessments of regional groundwater flow, much about the aquifer is still not well understood including controls on recharge rates, a crucial component of water management design. We review the trends in regional availability of surface and groundwater resources, their current status, and the effects of recent changes in management practices on groundwater decline in Mississippi and Arkansas. Global and regional climate projections are used to assess scenarios of sustainable aquifer use under current land use and management along with the potential for more widely practiced surface water capture and reuse to alleviate groundwater decline. Finally, we highlight crucial knowledge gaps and challenges associated with the development of water management practices for sustainable agricultural use in the region.

    This paper presents a decision support system (DSS) for sustainable development and environmental protection of agricultural regions developed in the framework of the Interreg-Archimed project entitled WaterMap (development and utilization of vulnerability maps for the monitoring and management of groundwater resources in the ARCHIMED areas). Its aim is to optimize the production plan of an agricultural region taking in account the available resources, the environmental parameters, and the vulnerability map of the region. The DSS is based on an optimization multicriteria model. The spatial integration of vulnerability maps in the DSS enables regional authorities to design policies for optimal agricultural development and groundwater protection from the agricultural land uses. The DSS can further be used to simulate different scenarios and policies by the local stakeholders due to changes on different social, economic, and environmental parameters. In this way, they can achieve alternative production plans and agricultural land uses as well as to estimate economic, social, and environmental impacts of different policies. The DSS is computerized and supported by a set of relational databases. The corresponding software has been developed in a Microsoft Windows XP platform, using Microsoft Visual Basic, Microsoft Access, and the LINDO library. For demonstration reasons, the paper includes an application of the DSS in a region of Northern Greece.

    For centuries, traditional agricultural systems have contributed to food and livelihood security throughout the world. Recognizing the ecological legacy in the traditional agricultural systems may help us develop novel sustainable agriculture. We examine how rice-fish coculture (RF), which has been designated a "globally important agricultural heritage system," has been maintained for over 1,200 y in south China. A field survey demonstrated that although rice yield and rice-yield stability are similar in RF and rice monoculture (RM), RF requires 68% less pesticide and 24% less chemical fertilizer than RM. A field experiment confirmed this result. We documented that a mutually beneficial relationship between rice and fish develops in RF: Fish reduce rice pests and rice favors fish by moderating the water environment. This positive relationship between rice and fish reduces the need for pesticides in RF. Our results also indicate a complementary use of nitrogen (N) between rice and fish in RF, resulting in low N fertilizer application and low N release into the environment. These findings provide unique insights into how positive interactions and complementary use of resource between species generate emergent ecosystem properties and how modern agricultural systems might be improved by exploiting synergies between species.

    SummaryAgriculture is the largest consumer of freshwater resources - around 70 percent of all freshwater withdrawals are used for food production. These agricultural products are traded internationally. A full understanding of water use is, therefore, impossible without understanding the international market for food and related products, such as textiles. Based on the global general equilibrium model GTAP-W, we offer a method for investigating the role of green (rain) and blue (irrigation) water resources in agriculture and within the context of international trade. We use future projections of allowable water withdrawals for surface water and groundwater to define two alternative water management scenarios. The first scenario explores a deterioration of current trends and policies in the water sector (water crisis scenario). The second scenario assumes an improvement in policies and trends in the water sector and eliminates groundwater overdraft world-wide, increasing water allocation for the environment (sustainable water use scenario). In both scenarios, welfare gains or losses are not only associated with changes in agricultural water consumption. Under the water crisis scenario, welfare not only rises for regions where water consumption increases (China, South East Asia and the USA). Welfare gains are considerable for Japan and South Korea, Southeast Asia and Western Europe as well. These regions benefit from higher levels of irrigated production and lower food prices. Alternatively, under the sustainable water use scenario, welfare losses not only affect regions where overdrafting is occurring. Welfare decreases in other regions as well. These results indicate that, for water use, there is a clear trade-off between economic welfare and environmental sustainability.

    Full Text Available Many common bird species have declined as a result of agricultural intensification and this could be mitigated by organic farming. We paired sites for habitat and geographical location on organic and nonorganic farms in Ontario, Canada to test a priori predictions of effects on birds overall, 9 guilds and 22 species in relation to candidate models for farming practices (13 variables, local habitat features (12 variables, or habitat features that influence susceptibility to predation. We found that: (1 Overall bird abundance, but not richness, was significantly (p < 0.05 higher on organic sites (mean 43.1 individuals per site than nonorganic sites (35.8 individuals per site. Significantly more species of birds were observed for five guilds, including primary grassland birds, on organic vs. nonorganic sites. No guild had higher richness or abundance on nonorganic farms; (2 Farming practice models were the best (Î"AIC < 4 for abundance of birds overall, primary grassland bird richness, sallier aerial insectivore richness and abundance, and abundance of ground nesters; (3 Habitat models were the best for overall richness, Neotropical migrant abundance, richness and abundance of Ontario-USA-Mexico (short-distance migrants and resident richness; (4 Predation models were the best for richness of secondary grassland birds and ground feeders; (5 A combination of variables from the model types were best for richness or abundance overall, 13 of 18 guilds (richness and abundance and 16 of 22 species analyzed. Five of 10 farming practice variables (including herbicide use, organic farm type and 9 of 13 habitat variables (including hedgerow length, proportion of hay were significant in best models. Risk modeling indicated that herbicide use could decrease primary grassland birds by one species (35% decline from 3.4 to 2.3 species per site. Organic farming could benefit species of conservation concern by 49% (an increase from 7.6 to 11.4 grassland birds. An

    Driven by growing pressure for a more sustainable operational practice, improvement on the classification of non-value added (waste) is one of the prerequisites to realize sustainability of a firm. While the use of the 7 (seven) types of the Ohno model now becoming a versatile tool to reveal the lean waste occurrence. In many recent investigations, the use of the Seven Waste model of Ohno is insufficient to cope with the types of waste occurred in industrial practices at various application levels. Intended to a narrowing down this limitation, this paper presented an improved waste classification model based on survey to recent studies discussing on waste at various operational stages. Implications on the waste classification model to the body of knowledge and industrial practices are provided.

    The necessity of transition of agriculture to sustainability is complicated by the necessity to increase production of local environmentally safe food, unemployment indigenous growth of living standards of the peasant community, stable and balanced nature management. Due to the difficult economic conditions of natural and agricultural development for the Komi Republic principle of food self-sufficiency is unacceptable, but the production of basic food products, for which favorable there are conditions, is objective necessity in the short term. Priority directions of development of the agricultural and fisheries sectors: the production of socially significant food products - potatoes, vegetables of the local range, milk, fresh meat, eggs, dietary, preservation and development of traditional industries, and collecting wild mushrooms and berries and its processing. Off forecast in the northern agricultural areas three scenarios selected: a base (slow), optimistic and pessimistic. For all versions of the forecast to be considered systemic crisis of the agricultural sector of the North is ongoing. Functioning of on sector under a particular scenario will depend on the factors and conditions that affect the stability of the agricultural enterprises and farms. At the base, especially under unfavorable conditions, negative external factors and conditions will prevail. The baseline scenario of recent years assumes the maintenance of the rate of change indicators of agriculture, of the levels of state industry conditions of interbranch exchange in agriculture, of access to economic entities in the financial markets, of the pricing and taxation policies, of relatively low investment opportunities to upgrade production capacity. In this embodiment the growth of agricultural production and its reduction will occur in suburban (peripheral areas). The optimistic scenario will be characterized by protectionist policies of the state, increase investment to improve soil fertility

    This paper comprises a selection tool for water disinfection methods for fresh produce pre- and postharvest practices. A variety of water disinfection technologies is available on the market and no single technology is the best choice for all applications. It can be difficult for end users to choose the technology that is best fit for a specific application. Therefore, the different technologies were characterized in order to identify criteria that influence the suitability of a technology for pre- or postharvest applications. Introduced criteria were divided into three principal components: (i) criteria related to the technology and which relate to the disinfection efficiency, (ii) attention points for the management and proper operation, and (iii) necessities in order to sustain the operation with respect to the environment. The selection criteria may help the end user of the water disinfection technology to obtain a systematic insight into all relevant aspects to be considered for preliminary decision making on which technologies should be put to feasibility testing for water disinfection in pre- and postharvest practices of the fresh produce chain.

    2017-06-23

    Dentistry is highly energy and resource intensive with significant environmental impact. Factors inherent in the profession such as enormous electricity demands of electronic dental equipment, voluminous water requirements, environmental effects of biomaterials (before, during and after clinical use), the use of radiation and the generation of hazardous waste involving mercury, lead etc have contributed towards this. With rising temperatures across the world due to global warming, efforts are being made worldwide to mitigate the effects of environmental damage by resorting to sustainability concepts and green solutions in a myriad of ways. In such a scenario, a professional obligation and social responsibility of dentists makes it imperative to transform the practice of dentistry from a hazardous to a sustainable one, by adopting environmental-friendly measures or 'green dentistry'. The NHS in the UK has been proactive in implementing sustainability in healthcare by setting targets, developing guidance papers, initiating steering groups to develop measures and implementing actions through its Sustainable Development Unit (SDU). Such sustainable frameworks, specific to dentistry, are not yet available and even the scientific literature is devoid of studies in this field although anecdotal narratives abound. Hence this paper attempts to present a comprehensive evaluation of the existing healthcare sustainability principles, for their parallel application in the field of dentistry and lays out a blueprint for integrating the two main underlying principles of sustainability - resource use efficiency and eliminating or minimising pollution - in the day-to-day practice. The article also highlights the importance of social values, community care, engaging stakeholders, economic benefits, developing policy and providing leadership in converting the concept of green dentistry into a practised reality.

  15. A review of sustainable facilities management knowledge and practice

    Full Text Available Sustainability is seen as a far-reaching issue now, and one which the facilities management [FM] profession cannot overlook. This paper explores current sustainable facilities management [SFM] knowledge and practice with specific focus on performance as part of a research focus toward proposing a sustainable FM performance management framework for sustainable healthcare waste management in Malaysia. This paper utilized a review of extant literature on the subject of SFM, FM performance and FM development in Malaysia as source of information. Findings reflect the increasing recognition of the need for the strategic FM function, and how facilities managers are best positioned to drive organizations’ sustainability agendas. In Malaysian context, this recognition is barely evident as findings show FM practice is still immature and predominantly operational. Unlike developed FM markets, FM relevance in Malaysia is being driven by the public sector. Also findings show a disharmony between organizations’ sustainability priority areas and the responsibilities for facilities managers to execute them where the sustainability policy of organizations prioritize one FM service and the facilities managers’ responsibilities prioritize another. As most of SFM implementation is driven by legislation this seems to strengthen the position that, organizations continue to view support services as non-value-adding, as unavoidable liabilities. The implication of this is the pressure on the FM function to continually express its strategic relevance to organizations by tangible value-adding performance output. This creates a new perspective to measuring and managing facilities performance. This paper therefore elevates the importance of FM performance management in SFM context taking into account the peculiar position of the facilities manager. This is seen as a way forward for FM to better express its value to the organization

    Fisheries and aquaculture make a crucial contribution to global food security, nutrition and livelihoods. However, the UN Sustainable Development Goals separate marine and terrestrial food production sectors and ecosystems. To sustainably meet increasing global demands for fish, the interlinkages among goals within and across fisheries, aquaculture and agriculture sectors must be recognized and addressed along with their changing nature. Here, we assess and highlight development challenges for fisheries-dependent countries based on analyses of interactions and trade-offs between goals focusing on food, biodiversity and climate change. We demonstrate that some countries are likely to face double jeopardies in both fisheries and agriculture sectors under climate change. The strategies to mitigate these risks will be context-dependent, and will need to directly address the trade-offs among Sustainable Development Goals, such as halting biodiversity loss and reducing poverty. Countries with low adaptive capacity but increasing demand for food require greater support and capacity building to transition towards reconciling trade-offs. Necessary actions are context-dependent and include effective governance, improved management and conservation, maximizing societal and environmental benefits from trade, increased equitability of distribution and innovation in food production, including continued development of low input and low impact aquaculture.

    2015-04-01

    In this paper, issues of agricultural drainage systems are introduced and discussed from the views of their former, current and future roles and functioning in the Czech Republic (CR). A methodologically disparate survey was done on thirty-nine model localities in CR with different intensity and state of land drainage systems, aimed at description of commonly occurred problems and possible adaptations of agricultural drainage as perceived by farmers, land owners, landscape managers or by protective water management. The survey was focused on technical state of drainage, fragmentation of land ownership within drained areas as well as on possible conflicts between agricultural and environmental interests in a landscape. Achieved results confirmed that there is obviously an increasing need to reassess some functions of prevailingly single-purpose agricultural drainage systems. Drainage intensity and detected unfavourable technical state of drainage systems as well as the risks connected with the anticipated climate change from the view of possible water scarcity claims for a complex solution. An array of adaptation options for agricultural drainage systems is presented, aiming at enhancement of water retention time and improvement of water quality. It encompasses additional flow-controlling measures on tiles or ditches, or facilities for making selected parts of a drainage system inoperable in order to retain or slow down the drainage runoff, to establish water accumulation zones and to enhance water self-cleaning processes. However, it was revealed that the question of landowner parcels fragmentation on drained land in CR would dramatically complicate design and realization of these measures. Presented solutions and findings are propounded with a respect to contemporary and future state policies and international strategies for sustainable agriculture, water management and environment.

    Nutrition science-based dietary advice urges changes that may have a great impact on agricultural systems. For example, the 2016 Dietary Guidelines for Americans (DGA) recommends greatly increased fruit and vegetable consumption, but the present domestic production is insufficient to accommodate large-scale adoption of these guidelines. Increasing production to the extent needed to meet the DGA will necessitate changes in an already stressed agriculture and food system and will require nutrition and agriculture professionals to come together in open and collegial discourse. All involved need to understand the stress placed on the food system by increasing populations, changing diets, and changing environments, and recognize the major diet-based public health challenges. Furthermore, there is a need to understand the intricate interplay of the myriad parts of the food system and the vast amount of work necessary to make even small changes. New systems approaches are needed, especially at the research level, where nutrition, public health, agriculture, and the food industry work together to solve interconnected problems. Future well-being depends on a sustainable food system that continues to deliver optimal health with minimal impact on the environment. © 2017 American Society for Nutrition.

    Field experiments were conducted in agricultural fields in which secondary wastewater of the City of Arad (Israel) is reused for irrigation. For sustainable agricultural production and safe groundwater recharge the secondary effluent is further polished by a combined two-stage membrane pilot system. The pilot membrane system consists of two main in row stages: Ultrafiltration (UF) and Reverse Osmosis (RO). The UF stage is efficient in the removal of the pathogens and suspended organic matter while the successive RO stage provides safe removal of the dissolved solids (salinity). Effluents of various qualities were applied for agricultural irrigation along with continuous monitoring of the membrane system performance. Best agricultural yields were obtained when applying effluent having minimal content of dissolved solids (after the RO stage) as compared with secondary effluent without any further treatment and extended storage. In regions with shallow groundwater reduced soil salinity in the upper productive layers, maintained by extra membrane treatment, will guarantee minimal dissolved solids migration to the aquifers and minimize salinisation processes.

    One of the significant environmental hazards of irrigated agriculture is the accumulation of salts in the soil. The presence of large quantities of certain soluble salts badly affects the physical, chemical, biological and fertility characteristics of the soils. This pollution of soil salinity and its toxic degradation directly affects plants, hence impacting the air filters of nature. The soil and water salinity has adversely reduced the yield of our major agricultural crops to an extent that agricultural sustainability is being threatened. Salinity has also dwindled the survival of marine life, livestock, in addition to damaging of construction works. The problem can be estimated from the fact that out of 16.2 m.ha of irrigated land of Pakistan, 6.3 . ha are salt affected in the Indus Plain. The state of water pollution can further be assessed from the fact that presently about 106 MAF of water is diverted from the rivers into the canals of the Indus Plain which contains 28 MT of salts. Due to soil and water pollution more than 40,000 ha of good irrigated land goes out of cultivation every year. This it has drastically reduced the potential of our agricultural lands. Hence, an estimated annual loss of Rs. 14,000 million has been reported due to this soil-water salinity pollution in Pakistan. Some management options to mitigate the soil - water salinity pollution are proposed. (author)

    The present study develops a composite environmental impact index (CEII) to evaluate the extent of environmental degradation in agriculture after successfully validating its flexibility, applicability and relevance as a tool. The CEII tool is then applied to empirically measure the extent of environmental impacts of High Yield Variety (HYV) rice cultivation in three districts of north-western Bangladesh for a single crop year (October, 2012-September, 2013). Results reveal that 27 to 69 per cent of the theoretical maximum level of environmental damage is created due to HYV rice cultivation with significant regional variations in the CEII scores, implying that policy interventions are required in environmentally critical areas in order to sustain agriculture in Bangladesh.

    Soil organisms are an integral component of ecosystems, but their activities receive little recognition in agricultural management strategies. Here we synthesize the potential of soil organisms to enhance ecosystem service delivery and demonstrate that soil biodiversity promotes multiple ecosystem functions simultaneously (i.e., ecosystem multifunctionality). We apply the concept of ecological intensification to soils and we develop strategies for targeted exploitation of soil biological traits. We compile promising approaches to enhance agricultural sustainability through the promotion of soil biodiversity and targeted management of soil community composition. We present soil ecological engineering as a concept to generate human land-use systems, which can serve immediate human needs while minimizing environmental impacts. Copyright © 2016 Elsevier Ltd.

    Full Text Available Plants have recently been recognized as meta-organisms due to a close symbiotic relationship with their microbiome. Comparable to humans and other eukaryotic hosts, plants also harbor a “second genome” that fulfills important host functions. These advances were driven by both “omics”-technologies guided by next-generation sequencing and microscopic insights. Additionally, these new results influence applied fields such as biocontrol and stress protection in agriculture, and new tools may impact (i the detection of new bio-resources for biocontrol and plant growth promotion, (ii the optimization of fermentation and formulation processes for biologicals, (iii stabilization of the biocontrol effect under field conditions, and (iv risk assessment studies for biotechnological applications. Examples are presented and discussed for the fields mentioned above, and next-generation bio-products were found as a sustainable alternative for agriculture.

    Full Text Available Great Recession is another proof that the current paradigm of economic growth should be changed. It ought to be applied to all sectors, including agriculture. The farming sector was strongly affected by substantial price increases of some products. It was especially painful for poorer consumers in developing and Third World countries, while its benefits were channelled mainly to big farmers and speculators in developed economies. Common Agricultural Policy could not avert this turbulence. The implementa-tion of the concept of sustainable development is a possible solution of this problem as its approach is more holistic and humanistic. However, the implementation of adequate reforms is very slow. It is a sign that leading US and EU policymakers attempt to stay within the limits of current model of growth.However, the second wave of price hikes may prove to be more lasting, which would further deepen income inequality.

  10. Conceptual Analysis: The Charcoal-Agriculture Nexus to Understand the Socio-Ecological Contexts Underlying Varied Sustainability Outcomes in African Landscapes

    Directory of Open Access Journals (Sweden)

    2017-06-01

    Full Text Available The production of charcoal is an important socio-economic activity in sub-Saharan Africa (SSA. Charcoal production is one of the leading drivers of rural land-use changes in SSA, although the intensity of impacts on the multi-functionality of landscapes varies considerably. Within a given landscape, charcoal production is closely interconnected to agriculture production both as major livelihoods, while both critically depend on the same ecosystem services. The interactions between charcoal and agricultural production systems can lead to positive synergies of impacts, but will more often result in trade-offs and even vicious cycles. Such sustainability outcomes vary from one site to another due to the heterogeneity of contexts, including agricultural production systems that affect the adoption of technologies and practices. Trade-offs or cases of vicious cycles occur when one-off resource exploitation of natural trees for charcoal production for short-term economic gains permanently impairs ecosystem functions. Given the fact that charcoal, as an important energy source for the growing urban populations and an essential livelihood for the rural populations, cannot be readily substituted in SSA, there must be policies to support charcoal production. Policies should encourage sustainable technologies and practices, either by establishing plantations or by encouraging regeneration, whichever is more suitable for the local environment. To guide context-specific interventions, this paper presents a new perspective—the charcoal-agriculture nexus—aimed at facilitating the understanding of the socio-economic and ecological interactions of charcoal and agricultural production. The nexus especially highlights two dimensions of the socio-ecological contexts: charcoal value chains and tenure systems. Combinations of the two are assumed to underlie varied socio-economic and ecological sustainability outcomes by conditioning incentive mechanisms to affect

    Full Text Available Introduction: Generally, subsidies are the amounts of government payments in order to provide all society members with minimum well-being. In several countries such as Iran, the agriculture sector is supported by different methods to achieve goals such as increasing farmers' income, supporting domestic producers and eliminating dependence on imports, preserving employment and reducing poverty. A significant part of agriculture subsidies has been allocated to energy resources, chemical fertilizers, seeds, agriculture machines, vaccines, animal toxins, the interest on bank loans, insurance fees, certain airplane services, distributing young saplings, and government guaranteed purchase of products. However, examining the subsidies system in Iran reveals that most government payments are in the agriculture sector and more specifically on energy resources. Recently, the extra low cost of energy in the agriculture sector, which has had certain government supports, has resulted in low productivity and environmental damage, and has resulted in increased demand for agricultural products due to population growth, changes in life pattern, deviation in energy cost in agricultural sector, environment destruction and influences on sustainable agriculture indicators. Moreover, among different production units, agriculture has the closest relationship with the environment. This relationship is a mutual.On the one hand, erosion and destruction of the environment along with pollution growth and shortage of water resources negatively influences the production and efficiency of agricultural products, and on the other hand, agricultural pollutants and irregular use of chemical fertilizers in this sector impose indispensable damages to the environment.This study aims to apply a partial equilibrium model in order to examine direct and indirect effects of reduction of energy subsidies on economic and environmental indicators of agricultural sustainability in the Qorveh

    The importance of agricultural products, their potential conversion to energy sources and their applications for fibre-reinforced construction materials is emphasized. Another potentially important technology is the conversion of sunlight into electricity such as occurs in the leaves of plants. Parallels with nature exist, even though conversions with inorganic materials have, until now, been promising. The ability to control chemical reactions is the subject throughout all the following chapters. The goal is to achieve high reaction efficiencies and to use fewer basic materials, both of which will lead to a reduction in environmental stress. Sustainable developments in chemistry can be described by two approaches: (1) Improvements in society, with challenges for chemistry; and (2) Improvement in the chemical sector itself. Both approaches are dealt with in this report. Five areas for development have been chosen in the discussions for `DTO-Chemie`: Integrated plant conversion (IPC), in particular Valorisation of plant parts for raw materials and energy; Biomass conversion (C1 Chemistry), in particular Technologies for (among others) C1-based chemicals and energy carriers; Photovoltaic cells (PSC), in particular Technologies for the conversion of solar light into electricity; Process Technology in Fine chemistry (PFC), in particular Methodology of manufacturing processes for Fine chemicals; and Sustainable Construction Materials (FRC); in particular Techniques for using fibre-reinforced composites in construction applications. These areas can be viewed as clusters of technologies, with a strong chemistry and agricultural component, which are necessary for achieving a sustainable future. Furthermore, it is important to recognise that technology requires a progressive development (technology lifecycle). The five areas of technology development are tested against a number of criteria: (1) Sustainability / leap / volume; (2) Horizon 2050; (3) Commitment from industry

    The Brazilian Cerrado area is in rapid decline because of the expansion of modern agriculture. In this study, we used extensive field data and a 30-year chronosequence of Landsat images (1980-2010) to assess the effects of time since conversion of Cerrado into agriculture upon soil chemical attributes and soybean/corn yield in the Alto do Rio Verde watershed. We determined the rates of vegetation conversion into agriculture, the agricultural land use time since conversion, and the temporal changes in topsoil (0-20 cm soil depth) and subsurface (20-40 cm) chemical attributes of the soils. In addition, we investigated possible associations between fertilization/over-fertilization and land use history detected from the satellites. The results showed that 61.8% of the native vegetation in the Alto do Rio Verde watershed was already converted into agriculture with 31% of soils being used in agriculture for more than 30 years. While other fertilizers in cultivated soils (e.g., Ca +2 , Mg +2 , and P) have been compensated over time by soil management practices to keep crop yield high, large reductions in C org (38%) and N tot (29%) were observed in old cultivated areas. Furthermore, soybean and cornfields having more than 10 years of farming presented higher values of P and Mg +2 than the ideal levels necessary for plant development. Therefore, increased risks of over-fertilization of the soils and environmental contamination with these macronutrients were associated with soybean and cornfields having more than 10 years of farming, especially those with more than 30 years of agricultural land use.

    Increasing number and activity of the population to meet the needs of their lives greatly affect the utilization of land resources. Land needs for activities of the population continue to grow, while the availability of land is limited. Therefore, there will be changes in land use. As a result, the problems faced by land degradation and conversion of agricultural land become non-agricultural. The objectives of this research are: (1) to determine parameter of spatial numerical classification of sustainable food agriculture in Badung Regency and Denpasar City (2) to know the projection of food balance in Badung Regency and Denpasar City in 2020, 2030, 2040, and 2050 (3) to specify of function of spatial numerical classification in the making of zonation model of sustainable agricultural land area in Badung regency and Denpasar city (4) to determine the appropriate model of the area to protect sustainable agricultural land in spatial and time scale in Badung and Denpasar regencies. The method used in this research was quantitative method include: survey, soil analysis, spatial data development, geoprocessing analysis (spatial analysis of overlay and proximity analysis), interpolation of raster digital elevation model data, and visualization (cartography). Qualitative methods consisted of literature studies, and interviews. The parameters observed for a total of 11 parameters Badung regency and Denpasar as much as 9 parameters. Numerical classification parameter analysis results used the standard deviation and the mean of the population data and projections relationship rice field in the food balance sheet by modelling. The result of the research showed that, the number of different numerical classification parameters in rural areas (Badung) and urban areas (Denpasar), in urban areas the number of parameters is less than the rural areas.

    Science and innovation are important components underpinning the agricultural and agri-food system in Canada. Canada's vast geographical area presents diverse, regionally specific requirements in addition to the 21st century agricultural challenges facing the overall sector. As the broader needs of the agricultural landscape have evolved and will continue to do so in the next few decades, there is a trend in place to transition towards a sustainable bioeconomy, contributing to reducing greenhouse gas emission and our dependency on non-renewable resources. We highlight some of the key policy drivers on an overarching national scale and those specific to agricultural research and innovation that are critical to fostering a supportive environment for innovation and a sustainable bioeconomy. As well, we delineate some major challenges and opportunities facing agriculture in Canada, including climate change, sustainable agriculture, clean technologies, and agricultural productivity, and some scientific initiatives currently underway to tackle these challenges. The use of various technologies and scientific efforts, such as Next Generation Sequencing, metagenomics analysis, satellite image analysis and mapping of soil moisture, and value-added bioproduct development will accelerate scientific development and innovation and its contribution to a sustainable and prosperous bioeconomy.

    This paper aims to summarize the achievements during the implementation process of good agricultural practice (GAP) in Chinese Materia Medica (CMM), and on basis of analyzing the existing problems of GAP, to propose further implementation of GAP in TCM growing. Since the launch of GAP in CMM growing ten years ago, it has acquired great achievements, including: (1) The promulgation of a series of measures for the administration of the GAP approval in the CMM growing; (2) The expanded planting area of CMM; (3) The increased awareness of standardized CMM growing among farmers and enterprises; (4) The establishment of GAP implementation bases for CMM growing; (5) The improvement of theory and methodology for CMM growing; (6) The development of a large group of experts and scholars in GAP approval for CMM production. The problems existing in the production include: (1) A deep understanding of GAP and its certification is still needed; (2) The distribution of the certification base is not reasonable; (3) The geo-economics effect and the backward farming practices are thought to be the bottlenecks in the standardization of CMM growing and the scale production of CMM; (4) Low comparative effectiveness limits the development of the GAP; (5) The base of breeding improved variety is blank; (6) The immature of the cultivation technique lead to the risk of production process; (7) The degradation of soil microbial and the continuous cropping obstacle restrict the sustainable development of the GAP base. To further promote the health and orderly GAP in the CMM growing, the authors propose: (1) To change the mode of production; (2) To establish a sound standard system so as to ensure quality products for fair prices; (3) To fully consider the geo-economic culture and vigorously promote the definite cultivating of traditional Chinese medicinal materials; (4) To strengthen the transformation and generalization of basic researches and achievements, in order to provide technical

    Full Text Available J. Russell Smith (1874–1966, a professor of geography at Columbia University, witnessed the devastation of soil erosion during his extensive travels. He first published his landmark text, Tree Crops, A Permanent Agriculture in 1929, in which he described the value of tree crops for producing food and animal feed on sloping, marginal, and rocky soils as a sustainable alternative to annual crop agriculture less suited to these lands. A cornerstone of his thesis was using wide germplasm collection and plant breeding to improve this largely underutilized and genetically unexploited group of plants to develop locally adapted, high-yielding cultivars for the many climatic zones of North America. Smith proposed an establishment of “Institutes of Mountain Agriculture” to undertake this work. For a variety of reasons, though, his ideas were not implemented to any great degree. However, our growing population’s increasing demands on natural resources and the associated environmental degradation necessitate that Smith’s ideas be revisited. In this review, his concepts, supported by modern scientific understanding and advances, are discussed and expanded upon to emphasize their largely overlooked potential to enhance world food and energy security and environmental sustainability. The discussion leads us to propose that his “institutes” be established worldwide and with an expanded scope of work.

    Soil degradation has been associated with a lack of adequate consideration of soil ecosystem services. We demonstrate a broadly applicable method for mapping changes in the supply of two priority soil ecosystem services to support decisions about sustainable land-use configurations. We used a landscape-scale study area of 302 km(2) in northern Victoria, south-eastern Australia, which has been cleared for intensive agriculture. Indicators representing priority soil services (soil carbon sequestration and soil water storage) were quantified and mapped under both a current and a future 25-year land-use scenario (the latter including a greater diversity of land uses and increased perennial crops and irrigation). We combined diverse methods, including soil analysis using mid-infrared spectroscopy, soil biophysical modelling, and geostatistical interpolation. Our analysis suggests that the future land-use scenario would increase the landscape-level supply of both services over 25 years. Soil organic carbon content and water storage to 30 cm depth were predicted to increase by about 11% and 22%, respectively. Our service maps revealed the locations of hotspots, as well as potential trade-offs in service supply under new land-use configurations. The study highlights the need to consider diverse land uses in sustainable management of soil services in changing agricultural landscapes.

    Plant growth promoting rhizobacteria (PGPR) shows an important role in the sustainable agriculture industry. The increasing demand for crop production with a significant reduction of synthetic chemical fertilizers and pesticides use is a big challenge nowadays. The use of PGPR has been proven to be an environmentally sound way of increasing crop yields by facilitating plant growth through either a direct or indirect mechanism. The mechanisms of PGPR include regulating hormonal and nutritional balance, inducing resistance against plant pathogens, and solubilizing nutrients for easy uptake by plants. In addition, PGPR show synergistic and antagonistic interactions with microorganisms within the rhizosphere and beyond in bulk soil, which indirectly boosts plant growth rate. There are many bacteria species that act as PGPR, described in the literature as successful for improving plant growth. However, there is a gap between the mode of action (mechanism) of the PGPR for plant growth and the role of the PGPR as biofertilizer-thus the importance of nano-encapsulation technology in improving the efficacy of PGPR. Hence, this review bridges the gap mentioned and summarizes the mechanism of PGPR as a biofertilizer for agricultural sustainability.

  8. Water and solute balances as a basis for sustainable irrigation agriculture

    2015-04-01

    The growing development of irrigated agriculture is necessary for the sustainable production of the food required by the increasing World's population. Such development is limited by the increasing scarcity and low quality of the available water resources and by the competitive use of the water for other purposes. There are also increasing problems of contamination of surface and ground waters to be used for other purposes by the drainage effluents of irrigated lands. Irrigation and drainage may cause drastic changes in the regime and balance of water and solutes (salts, sodium, contaminants) in the soil profile, resulting in problems of water supply to crops and problems of salinization, sodification and contamination of soils and ground waters. This is affected by climate, crops, soils, ground water depth, irrigation and groundwater composition, and by irrigation and drainage management. In order to predict and prevent such problems for a sustainable irrigated agriculture and increased efficiency in water use, under each particular set of conditions, there have to be considered both the hydrological, physical and chemical processes determining such water and solute balances in the soil profile. In this contribution there are proposed the new versions of two modeling approaches (SOMORE and SALSODIMAR) to predict those balances and to guide irrigation water use and management, integrating the different factors involved in such processes. Examples of their application under Mediterranean and tropical climate conditions are also presented.

  9. Design and Concept of an Energy System Based on Renewable Sources for Greenhouse Sustainable Agriculture

    2018-05-01

    Full Text Available Bio-organic greenhouses that are based on alternative resources for producing heat and electricity stand out as an efficient option for the sustainable development of agriculture, thus ensuring good growth and development of plants in all seasons, especially during the cold season. Greenhouses can be used with maximum efficiency in various agricultural lands, providing ideal conditions of temperature and humidity for short-term plant growing, thereby increasing the local production of fruit and vegetables. This paper presents the development of a durable greenhouse concept that is based on complex energy system integrating fuel cells and solar panels. Approaching this innovative concept encountered a major problem in terms of local implementation of this type of greenhouses because of the difficulty in providing electrical and thermal energy from conventional sources to ensure an optimal climate for plant growing. The project result consists in the design and implementation of a sustainable greenhouse energy system that is based on fuel cells and solar panels.

    Several models have been developed over the past decade to estimate CH4 emission from rice paddies. However, few models have been validated against field measurements with various parameters of soil, climate and agricultural practice. Thus reliability of the model's performance remains questionable particularly when extrapolating the model from site microscale to regional scale. In this paper, modification to the original model focuses on the effect of water regime on CH4 production/emission and the CH4 transport via bubbles. The modified model, named as CH4MOD, was then validated against a total of 94 field observations. These observations covered main rice cultivation regions from northern (Beijing, 40°30'N, 116°25'E) to southern China (Guangzhou, 23°08'N, 113°20'E), and from eastern (Hangzhou, 30°19'N, 120°12'E) to southwestern (Tuzu, 29°40'N, 103°50'E) China. Both single rice and double rice cultivations are distributed in these regions with different irrigation patterns and various types of organic matter incorporation. The observed seasonal amount of CH4 emission ranged from 3.1 to 761.7 kg C ha-1 with an average of 199.4 ± 187.3 kg C ha-1. In consonance with the observations, model simulations resulted in an average value of 224.6 ± 187.0 kg C ha-1, ranging from 13.9 to 824.3 kg C ha-1. Comparison between the computed and the observed seasonal CH4 emission yielded a correlation coefficient r2 of 0.84 with a slope of 0.92 and an intercept of 41.1 (n = 94, p < 0.001). It was concluded that the CH4MOD can reasonably simulate CH4 emissions from irrigated rice fields with a minimal number of inputs and parameters.

    Transformed from the largest wetland system on the west coast of the United States to agriculture, the Sacramento-San Joaquin Delta is an extreme teaching example of anthropogenic threats to sustainability. For over 6,000 years, over 280,000 ha of intertidal freshwater marsh accreted due to seal level rise and sediment deposition. Farming of organic soils since 1850 resulted in land subsidence caused primarily by oxidation. Over 2 billion cubic meters of soil were lost resulting in elevations on Delta islands ranging from -1 to -8 m and increased risk of levee failures and water supply disruption. Alteration of water flows and habitat caused dramatic declines in aquatic species. A cycle in which oxidation of organic soils leads to deepening of drainage ditches to maintain an aerated root zone which in turn results in sustained oxidation and subsidence is perpetuated by the momentum of the status quo despite evidence that agricultural practices are increasingly unsustainable. Flooding of the soils breaks the oxidation/subsidence cycle. We assessed alternate land uses and the carbon market as a potential impetus for change. Using the peer-reviewed and locally calibrated SUBCALC model, we estimated net global warming potential for a range of scenarios for a representative island, from status quo to incorporating significant proportions of subsidence-mitigating land use. We analyzed economic implications by determining profit losses or gains when a simulated GHG offset market is available for wetlands using a regional agricultural production and economic optimization model, We estimated baseline GHG emissions at about 60,000 tons CO2-e per year. In contrast, modeled implementation of rice and wetlands resulted in substantial emissions reductions to the island being a net GHG sink. Subsidence would be arrested or reversed where these land uses are implemented. Results of economic modeling reveal that conversion to wetlands can have significant negative farm financial

    Full Text Available The Loess Plateau in China receives lots of attention from around the world. The expansion of bad agricultural practices for hundreds of years aggravated the soil erosion on the Loess Plateau, however, and a lot of efforts were and are being made to reduce the serious soil erosion as well as regional poverty. Agricultural development of the Loess Plateau is still confronted with intricate challenges such as food concerns, environment concerns, and regional poverty. The strategy of development towards sustainability offers a possible and important way to face the challenges. This study tried to develop a holistic “variation-selection-replication-retention” model to analyze the transformation of agricultural development from an evolutionary view which is generally integrative. It is indicated that policies should be lively and vibrant organisms full of innovations owning to ever-changing environment in the evolutionary view. Under this analytical framework, one possible path from serious soil erosion region to region with sustainable agriculture could be recognized in the case study of Fuxian County: serious soil erosion regions → regions with poor production conditions → production-optimized regions → regions with developed agriculture → regions with sustainable agriculture. Diversified integrative development is suggested due to regional differences and the possible developing order in Fuxian County. State-subsidized “Grain for Green” policy and diversified land use are necessary for the transformation of serious soil erosion regions which are usually trapped in regional poverty. To the transformation of regions with poor production conditions, a state-subsidized “production optimization” policy and diversified land use deserve to be considered, due to regional poverty in regions with poor production conditions. Agricultural scale operation is priority for the transformation of production-optimized regions towards

    Public health clinical educators and practicing public health nurses (PHNs) are experiencing challenges in creating meaningful clinical learning experiences for nursing students due to an increase in nursing programs and greater workload responsibilities for both nursing faculty and PHNs. The Henry Street Consortium (HSC), a collaborative group of PHNs and nursing faculty, conducted a project to identify best practices for public health nursing student clinical learning experiences. Project leaders surveyed HSC members about preferences for teaching-learning strategies, facilitated development of resources and tools to guide learning, organized faculty/PHN pilot teams to test resources and tools with students, and evaluated the pilot team experiences through two focus groups. The analysis of the outcomes of the partnership engagement project led to the development of the Partnership Engagement Model (PEM), which may be used by nursing faculty and their public health practice partners to guide building relationships and sustainable partnerships for educating nursing students. © 2017 Wiley Periodicals, Inc.

    Over the last several decades, voluntary certification programs have become a key approach to promote sustainable supply chains for agricultural commodities. These programs provide premiums and other benefits to producers for adhering to environmental and labor practices established by the certifying entities. Following the principles of Cochrane Reviews used in health sciences, we assess evidence to evaluate whether voluntary certification of tropical agricultural commodities (bananas, cocoa, coffee, oil palm, and tea) has achieved environmental benefits and improved economic and social outcomes for small-scale producers at the level of the farm household. We reviewed over 2600 papers in the peer-review literature and identified 24 cases of unique combinations of study area, certification program, and commodity in 16 papers that rigorously analyzed differences between treatment (certified households) and control groups (uncertified households) for a wide range of response variables. Based on analysis of 347 response variables reported in these papers, we conclude that certification is associated on average with positive outcomes for 34% of response variables, no significant difference for 58% of variables, and negative outcomes for 8% of variables. No significant differences were observed for different categories of responses (environmental, economic and social) or for different commodities (banana, coffee and tea), except negative outcomes were significantly less for environmental than other outcome categories (p = 0.01). Most cases (20 out of 24) investigated coffee certification and response variables were inconsistent across cases, indicating the paucity of studies to conduct a conclusive meta-analysis. The somewhat positive results indicate that voluntary certification programs can sometimes play a role in meeting sustainable development goals and do not support the view that such programs are merely greenwashing. However, results also indicate that

    Full Text Available This study examines employee involvement in organisational affairs as an important facet of social sustainability in the Nigerian banking sector, because providing good customer service requires committed employees rather than coerced labour. Data extracted through quantitative content analysis from the financial reports of fifteen commercial banks were analysed using descriptive statistics, Z test, one-way ANOVA, correlation and regression analysis techniques. e study found that employee involvement correlates positively and significantly with organisational performance; and banks differ in performance on the account of the level of employee involvement; firms with deeper level of employee involvement performed better than others with shallow level of employee involvement, thus stressing the relevance of employee involvement as an aspect of social sustainability business practices. Organisations are enjoined to involve their employees more to achieve better results; and embrace the modern philosophy of regarding employees as strategic resources that can be used to bolster core competence.

    Located in the North-Western Europe the terrestrial continuum that includes the Seine, Somme, and Scheldt River basins offers an interesting example of a transborder territory (France, Belgium, and Netherlands) with high-intensity anthropogenic pressures. It well-illustrates the rapid development of modern agriculture in industrialised countries and the resulting severe alteration of water resources and jeopardising the capacity of rural territories to produce drinking water. The corresponding nutrient loads delivered then into the Southern Bight of the North Sea, strongly affect the ecological functioning of the coastal zone. An integrated ‘river-ocean’ assessment, coupling two deterministic models - the SENEQUE RIVESTRAHLER model simulating nutrient dynamic in the drainage network and the MIRO model describing the ecological functioning coastal ecosystem - points out the relevance of current policy based measures (improvement of waste water treatment) to mitigate phosphorous emissions, while the nitrogen pollution related to agriculture will remain critical despite the implementation of classical management measure (good agricultural practices). Therefore and irrespectively of the current political agenda, a more radical alternative is established, consisting of a generalised shift to an integrated agriculture of all agricultural areas in the three basins, excluding the use of synthetically compounded fertilisers and the importation of livestock feed. Such scenario aims at evaluating whether agriculture, by essence, can conciliate (i) the demand for food and feed by local populations, (ii) a good ecological functioning of aquatic ecosystems and (iii) a balanced nutrient status for the adjacent coastal area. This scenario involves an increased livestock density in the Seine and Somme and a decrease in livestock in the Scheldt basin. It leads to a significant reduction of agricultural production that finally brings the three basins closer to autotrophy

    Full Text Available Introduction Fast switch to sustainable agriculture patterns is not impossible for many farmers. However to achieve perfect sustainable in agro-ecosystems which are friendly with environment, changing conventional to sustainable agriculture should be carried slowly. For this purpose, three effective steps were mentioned: first level is increasing of inputs efficiency such as fertilizer and chemical pesticides which used in conventional agriculture now. Second level is related to changing inputs by friendly environmental inputs as alternative inputs and the final level is redesigning of the agro-ecosystems that its function is based on series of ecological process. On the other hand, achieving sustainable agriculture requires higher efficiency of inputs and many process should be replaced by friendly environmental inputs with chemical inputs and new system is designed based on ecological principles. The objective of this study was to offer approaches for improving inputs use efficiency as first step to transition from conventional to sustainable agriculture. Material and Methods In order to evaluate the transition status from conventional to sustainable agriculture in agro-ecosystems of Iran, scientific resource and researches that was performed about increasing of inputs efficiency as first step to transition from conventional to sustainable agriculture was studied. For this purpose, 177 studies that had been performed about using different inputs and its efficiency in various crops were assessed. Applied inputs included water, nitrogen and herbicides and studied plants included cereals (wheat, barley, rice, maize and sorghum, beans (bean, pea and lentil, oil crops (canola, sunflower, safflower and sesame, medicinal plants, potato, sugar beet and cotton. In this study, average and range of inputs use efficiency in different crops and also the relationship between increasing of inputs application with their use efficiency was assessed. In the

    China’s grain-for-green policy (GFGP) was implemented with the goal of improving ecological security. Consequently, agricultural energy and agrochemical inputs have been significantly increased to improve food security and to increase the income of farmers in the regions where the GFGP was implemented. In analysis of the sustainability of the agricultural system affected by the GFGP, it is essential to consider both economic profitability and environmental sustainability. Using Yanchi County as a case study area, this study used an emergy synthesis to examine the sustainability of the agricultural system before and after the GFGP in Northwest China. We found that the total emergy input and energy output of the agricultural system in the study area increased from 1991 to 2008; however, the sustainability of the system declined, and this decline was especially evident after the GFGP was launched in 2001. Increasing inputs of non-renewable purchased resources will not only reduce the effectiveness of the GFGP in Northwest China, but also hinder the implementation of the energy-saving and emission-reduction policy that China launched in 2005. We suggest that sustainable agricultural development in Northwest China should be based on effective use of renewable resources and development of a low-carbon agricultural economy. - Highlights: • The total emergy input and energy output of the study system increased from 1991 to 2008. • The change of each emergy index was more evident after the GFGP launched in 2001. • The increase in input of non-renewable purchased resources will gradually reduce the function of the GFGP in West China. • Agricultural development in West China should be based on organic agriculture

    Full Text Available The implementation of the Sustainable Development Strategy through the Sustainable Development Goals 2015-2030 needs take into consideration the EU’ package from December 2015 concerning the achievement of the Circular Economy under the vision of the 3R - Recycle, Reuse, Reduce. The concept of Circular Economy has started to develop in response to the crisis of the traditional model and the need to deal with limited resources. A key role in the pursuit and implementation of circular economy is taken by investments in innovation and technologies that enhance the scraps of industrial and / or agricultural sectors. This can lead not only to a reduction of waste and hence environmental impacts but also in net savings for businesses of up to 604 billion Euros throughout the European Union, in line with the global framework (Sustainable Development Goals 2015 -2030. The paper try to demonstrate through an inductive model, several tables, figures and our analysis that the success of the Strategy of Sustainable Development depend, in the next years, by the application of the best practices of the Circular Economy.

    Water is vital for plant growth, development and productivity. Permanent or temporary water deficit stress limits the growth and distribution of natural and artificial vegetation and the performance of cultivated plants (crops) more than any other environmental factor. Productive and sustainable agriculture necessitates growing plants (crops) in arid and semiarid regions with less input of precious resources such as fresh water. For a better understanding and rapid improvement of soil-water stress tolerance in these regions, especially in the water-wind eroded crossing region, it is very important to link physiological and biochemical studies to molecular work in genetically tractable model plants and important native plants, and further extending them to practical ecological restoration and efficient crop production. Although basic studies and practices aimed at improving soil water stress resistance and plant water use efficiency have been carried out for many years, the mechanisms involved at different scales are still not clear. Further understanding and manipulating soil-plant water relationships and soil-water stress tolerance at the scales of ecology, physiology and molecular biology can significantly improve plant productivity and environmental quality. Currently, post-genomics and metabolomics are very important in exploring anti-drought gene resources in various life forms, but modern agriculturally sustainable development must be combined with plant physiological measures in the field, on the basis of which post-genomics and metabolomics have further practical prospects. In this review, we discuss physiological and molecular insights and effects in basic plant metabolism, drought tolerance strategies under drought conditions in higher plants for sustainable agriculture and ecoenvironments in arid and semiarid areas of the world. We conclude that biological measures are the bases for the solutions to the issues relating to the different types of

    Most global strategies for future food security focus on sustainable intensification of production of food and involve increased use of nitrogen fertilizer and manure. The external costs of current high nitrogen (N) losses from agriculture in the European Union, are 0.3-1.9% of gross domestic product (GDP) in 2008. We explore the potential of sustainable extensification for agriculture in the EU and The Netherlands by analysing cases and scenario studies focusing on reducing N inputs and livestock densities. Benefits of extensification are higher local biodiversity and less environmental pollution and therefore less external costs for society. Extensification also has risks such as a reduction of yields and therewith a decrease of the GDP and farm income and a smaller contribution to the global food production, and potentially an i0ncrease of global demand for land. We demonstrate favourable examples of extensification. Reducing the N fertilization rate for winter wheat in Northwest Europe to 25-30% below current N recommendations accounts for the external N cost, but requires action to compensate for a reduction in crop yield by 10-20%. Dutch dairy and pig farmers changing to less intensive production maintain or even improve farm income by price premiums on their products, and/or by savings on external inputs. A scenario reducing the Dutch pig and poultry sector by 50%, the dairy sector by 20% and synthetic N fertilizer use by 40% lowers annual N pollution costs by 0.2-2.2 billion euro (40%). This benefit compensates for the loss of GDP in the primary sector but not in the supply and processing chain. A 2030 scenario for the EU27 reducing consumption and production of animal products by 50% (demitarean diet) reduces N pollution by 10% and benefits human health. This diet allows the EU27 to become a food exporter, while reducing land demand outside Europe in 2030 by more than 100 million hectares (2%), which more than compensates increased land demand when

    Full Text Available Purpose: The objective of the present study is to select some feasible and sustainable logistic practices in order to improve the urban freight distribution in Bilbao city. Design/methodology/approach: After a thorough literature review and a benchmarking, Analytic Hierarchy Process (AHP techniques were used in order to support the decision making processes in order to select the most interesting practices. The criteria used for this selection were based on four factors: (1 improvement of the city freight distribution, (2 implementation possibility, (3 short and medium term applicability and (4 impact on the citizens of Bilbao. Findings: The paper identifies some specific problems that must be faced during the last stage of the logistics chain, where products are usually delivered to final customers in the urban environment. Research limitations/implications: Not all good urban freight distribution practices can be applied universally to all types of towns. Therefore, it is necessary to design some practices specifically to each particular city according to the physical characteristics of the city, the companies’ motivation and the citizens’ habits. Practical implications: All the agents involved in the city freight distribution should be aware of the benefits and problems that their actions cause. Originality/value: This study was carried out from a wide perspective that included researchers, logistics operators and local authorities.

    Full Text Available This study analyzes the changes osberved in the agri-food system with the advent of logistical management of the flow of goods and information along the food supply chain. Agri-food functions and responsibilities towards society are also analyzed. This field of research has been widely explored in recent years following the development of the Corporate Social Responsibility (CSR certification in agri-business. The analysis starts by examining the coherence of the ethical basis of human choices in a homo oeconomicus framework in which social relationships are merely exploitable activities. CSR development is then studied in the light of the new stakeholder theory for firms. The main fields of economic research into sustainable development and the most important goals achieved are examined and the methodological perspectives of agricultural economics research will also be discussed.

    Little is known regarding sustainability of evidence-based practices (EBPs) following implementation. This article reports sustainability of evidence-based acute pain management practices in hospitalized older adults following testing of a multifaceted Translating Research Into Practice (TRIP) implementation intervention. A cluster randomized trial with follow-up period was conducted in 12 Midwest U.S. hospitals (six experimental, six comparison). Use of evidence-based acute pain management practices and mean pain intensity were analyzed using generalized estimating equations across two time points (following implementation and 18 months later) to determine sustainability of TRIP intervention effects. Summative Index scores and six of seven practices were sustained. Experimental and comparison group differences for mean pain intensity over 72 hours following admission were sustained. Results revealed most evidence-based acute pain management practices were sustained for 18 months following implementation. Further work is needed to identify factors affecting sustainability of EBPs to guide development and testing of sustainability strategies.

  13. Soil carbon sequestration, carbon markets, and conservation agriculture practices: A hypothetical examination in Mozambique

    Full Text Available Payments for Environmental Services (PES are relatively novel mechanisms whereby the adoption of sustainable management practices by a stakeholder is rewarded by incentives linked to external markets. Adoption of PES for conservation agricultural practices (CAPS by smallholder farmers may provide opportunities to increase household income or cover the technology costs of adoption if the carbon sequestration benefits of CAPS are quantifiable, adoption rates are accelerated and maintained, a mechanism exists whereby carbon sequestration services can be compensated, and carbon offset exchange markets are viable. This research suggests a methodology to examine a PES market for carbon offsets generated by the adoption of CAPS by farmers in Mozambique. Assuming a cumulative adoption of 60% over a 20-year period, revenue from PES market participation to CA adopters was two times higher than revenue earned when disadoption occurred midway through the simulation. Lower adoption targets are associated with higher per household returns when fertilizer rates typical to the region are increased. Establishing and maintaining a sustainable PES system in the study region would require significant investment in time and resources. The lack of on-the-ground institutions or local support for such a program would also challenge successful implementation. Finally, the programs where participant success depends on external markets, such as the hypothetical one suggested here, are subject to the ebb and flow of foreign demand for carbon offsets. Addressing these three broad constraints to a PES/CAPS program in the region would require grass-roots driven policy initiatives with buy-in at multiple social, economic, and political levels.

    Health risks associated to practical activities in farm and agriculture are increasing all over the world. These risks are depending from technology and chemicals substances abuse. Urban agriculture specifically constitutes a challenge for producers and researchers. Agricultural food production, held inside of the cities, looking for sustainable productions is developed in risky scenarios where it is possible to found environmental pollutants such as heavy metals. Environmental pollutants may to contaminate humans throughout different pathways. The analysis of factors related to agricultural working strategies of urban farm workers, the precedent knowledgement about production places and analytical data related to composition and properties of these sites, are significant criteria for proper management of ecosystems. Qualitative analysis research tool such as expert group criteria is a suitable method for field research in this area. It was determined that the precedent use of soil, the use of fertilizers and phytosanitary products are key elements to be taken into account for successful management of agroecosystems and for health risk prevention related to the possible influence of heavy metals in farm practice

    Full Text Available The rich natural potential for agriculture in Romania is contrasting with the low level of economic performance. Progress toward sustainable development in rural areas depends on processes that lead to increased valuation of the natural resources by cropping and livestock breeding, capturing more value by growing the number of processing stages performed at national level for food production, improvements in the distribution of benefits with special focus on rural population, harnessing the benefits of stewarding natural ecosystems that play a key role for the overall wellbeing of the population, diversifying the structure of economic activities, and encouraging entrepreneurial involvement. European policies of rural development are supporting most of these processes, but within the national context there encountered specific challenges born by the low level of maturation for property relationships, fragmentation of land ownership and cropping plots, cultural patterns that create strong resistance to change, and lack of financial resources. The paper highlights several aspects in order to assess at what extent the Romanian agriculture is making progress toward European requirements.

    The toxicity of organophosphate insecticides for nontarget organism has been the subject of extensive research for sustainable agriculture. Pakistan has banned the use of methyl/ethyl parathions, but they are still illegally used. The present study is an attempt to estimate the residual concentration and to suggest remedial solution of adsorption by different types of soils collected and characterized for physicochemical parameters. Sorption of pesticides in soil or other porous media is an important process regulating pesticide transport and degradation. The percentage removal of methyl parathion and ethyl parathion was determined through UV-Visible spectrophotometer at 276 nm and 277 nm, respectively. The results indicate that agricultural soil as compared to barren soil is more efficient adsorbent for both insecticides, at optimum batch condition of pH 7. The equilibrium between adsorbate and adsorbent was attained in 12 hours. Methyl parathion is removed more efficiently (by seven orders of magnitude) than ethyl parathion. It may be attributed to more available binding sites and less steric hindrance of methyl parathion. Adsorption kinetics indicates that a good correlation exists between distribution coefficient (Kd) and soil organic carbon. A general increase in Kd is noted with increase in induced concentration due to the formation of bound or aged residue. PMID:24689059

    2017-06-01

    Full Text Available Smallholder farmers are the main producers of the world’s food and they will have to increase production by up to 100 percent by 2050 to feed the growing population. This must be achieved while preserving natural resources and that is why sustainable agricultural mechanization (SAM will be fundamental to the process. SAM is climate-smart and environmentally benign and essentially means no-till conservation agriculture, which requires specific mechanization inputs. Principally, these are seeders and planters capable of penetrating soil surface vegetative cover to deposit seed and fertilizer at the required depth and spacing; and equipment for management of cover crops and weeds. Mechanization is required not only for crop production, but also for processing and along the entire value chain. Mechanization inputs are usually expensive and so specialist service provision will be the indicated way forward. This will need collaboration from both the private and public sectors and will involve public-private partnerships to be developed in one form or another. Given the poor track record of public sector mechanization provision, the delivery of SAM should be firmly in the hands of the private sector that should be committed to SAM principles or otherwise be incentivized to the concept through smart subsidies. Improved information flows via smallholder farmer-friendly innovation platforms; and continuing development and testing of SAM technologies via regional centres of excellence will both be required—especially for sub-Saharan Africa.

  20. Sustainable pest regulation in agricultural landscapes: a review on landscape composition, biodiversity and natural pest control.

    Science.gov (United States)

    Bianchi, F J J A; Booij, C J H; Tscharntke, T

    2006-07-22

    Agricultural intensification has resulted in a simplification of agricultural landscapes by the expansion of agricultural land, enlargement of field size and removal of non-crop habitat. These changes are considered to be an important cause of the rapid decline in farmland biodiversity, with the remaining biodiversity concentrated in field edges and non-crop habitats. The simplification of landscape composition and the decline of biodiversity may affect the functioning of natural pest control because non-crop habitats provide requisites for a broad spectrum of natural enemies, and the exchange of natural enemies between crop and non-crop habitats is likely to be diminished in landscapes dominated by arable cropland. In this review, we test the hypothesis that natural pest control is enhanced in complex patchy landscapes with a high proportion of non-crop habitats as compared to simple large-scale landscapes with little associated non-crop habitat. In 74% and 45% of the studies reviewed, respectively, natural enemy populations were higher and pest pressure lower in complex landscapes versus simple landscapes. Landscape-driven pest suppression may result in lower crop injury, although this has rarely been documented. Enhanced natural enemy activity was associated with herbaceous habitats in 80% of the cases (e.g. fallows, field margins), and somewhat less often with wooded habitats (71%) and landscape patchiness (70%). The similar contributions of these landscape factors suggest that all are equally important in enhancing natural enemy populations. We conclude that diversified landscapes hold most potential for the conservation of biodiversity and sustaining the pest control function.

    The report entitled Climate Change Impacts and Adaptation : A Canadian Perspective, presents a summary of research regarding the impacts of climate change on key sectors over the past five years as it relates to Canada. This chapter on agriculture describes how climate change will affect primary agriculture production in Canada with particular focus on potential adaptation options, and vulnerability of agriculture at the farm level. Agriculture is a vital part of the Canadian economy, although only 7 per cent of Canada's land mass is used for agricultural purposes due to the limitations of climate and soils. Most parts of Canada are expected to experience warmer conditions, longer frost-free seasons and increased evapotranspiration. The impacts of these changes on agriculture will vary depending on precipitation changes, soil conditions, and land use. Northern regions may benefit from longer farming seasons, but poor soil conditions will limit the northward expansion of agricultural crops. Some of the negative impacts associated with climate change on agriculture include increased droughts, changes in pest and pathogen outbreaks, and moisture stress. In general, it is expected that the positive and negative impacts of climate change would offset each other. 74 refs., 2 tabs., 1 fig

    Keeping in view, the challenges concerning agro-ecosystem and environment, the recent developments in biotechnology offers a more reliable approach to address the food security for future generations and also resolve the complex environmental problems. Several unique features of cyanobacteria such as oxygenic photosynthesis, high biomass yield, growth on non-arable lands and a wide variety of water sources (contaminated and polluted waters), generation of useful by-products and bio-fuels, enhancing the soil fertility and reducing green house gas emissions, have collectively offered these bio-agents as the precious bio-resource for sustainable development. Cyanobacterial biomass is the effective bio-fertilizer source to improve soil physico-chemical characteristics such as water-holding capacity and mineral nutrient status of the degraded lands. The unique characteristics of cyanobacteria include their ubiquity presence, short generation time and capability to fix the atmospheric N2. Similar to other prokaryotic bacteria, the cyanobacteria are increasingly applied as bio-inoculants for improving soil fertility and environmental quality. Genetically engineered cyanobacteria have been devised with the novel genes for the production of a number of bio-fuels such as bio-diesel, bio-hydrogen, bio-methane, synga, and therefore, open new avenues for the generation of bio-fuels in the economically sustainable manner. This review is an effort to enlist the valuable information about the qualities of cyanobacteria and their potential role in solving the agricultural and environmental problems for the future welfare of the planet.

    2015-05-01

    Full Text Available Conservation agriculture (CA is an increasingly adopted production system to meet the goals of sustainable crop production intensification in feeding a growing world population whilst conserving natural resources. Mechanization (especially power units, seeders, rippers and sprayers is a key input for CA and smallholder farmers often have difficulties in making the necessary investments. Donors may be able to provide mechanization inputs in the short term, but this is not a sustainable solution as a machinery input supply chain needs to be built up to continue availability after external interventions cease. Local manufacture should be supported, as was the case in Brazil, but this is a slow development process, especially in sub-Saharan Africa. A more immediate solution is to equip and train CA service provision entrepreneurs. With the right equipment, selected for the needs of their local clientele, and the right technical and business management training, such entrepreneurs can make a livelihood by supplying high quality CA and other mechanization services on a fully costed basis. Elements of the required training, based on extensive field experience, are provided. To catalyse the growth of CA providers’ business, the market can be stimulated for an initial period by issuing e-vouchers for services and inputs.

    1999-01-01

    Soil erosion is one of the major causes of nutrient depletion in sub-Saharan Africa. Highlights of losses from erosion can be used to explain why agricultural production in this region is not sustainable. annual macronutrient losses were calculated from experimental results at 8 sites in Kenya between 1986 and 1990. these losses were used along with the current local prices of fertiliser to estimate the annual national budget required for there replenishment. On average, 5.72, 29.3 and 0.82 kg ha -1 yr -1 of N, P and K, respectively, were lost annually. These losses are determined by soil types, slope, crop cover characteristics and rainfall amounts. soil losses can be reduced by terracing, contour farming and intercropping to improve crop cover. These efforts reduce the adverse effects of sporadic rainfall on fragile soil types. in order to ensure sustainability however, control measures have to be supplemented by national additions of 64 000 t, 323 000 t and 10 000 t of N, P and K respectively per year. The equivalent costs of these fertilisers will be Ksh 1,408 Ksh 8721 Ksh 220 million for the respective nutrients. This would require a total of some US$256 million (Ksh 10 349 million) annually from the national budget

    The Yongding River System is an important water source for the northeastern Chinese provinces Shanxi, Hebei, Beijing, and Tianjin. The Guanting Reservoir within this river system is one of the major water sources for Beijing, which is about 70 km away. Original planning assumed a discharge of 44 m3/s for the reservoir, but the current mean discharge rate is only about 5 m3/s; there is often hardly any discharge at all. Water scarcity is a major threat for the socio-economic development of the area. The situation is additionally aggravated by climate change impacts. Typical upstream-downstream conflicts with respect to water quantity and quality requests are mixed up with conflicts between different sectors, mainly mining, industry, and agriculture. These conflicts can be observed on different administrative levels, for example between the provinces, down to households. The German-Chinese research project "Sustainable water and agricultural land use in the Guanting Watershed under limited water resources" investigates problems and solutions related to water scarcity in the Guanting Catchment. The aim of the project is to create a vulnerability study in order to assess options for (and finally achieve) sustainable water and land use management in the Guanting region. This includes a comprehensive characterization of the current state by gap analysis and identification of pressures and impacts. The presentation gives an overview of recent project results regarding regionalization of global change scenarios and specification for water supply, evaluation of surface water quantity balances (supply-demand), evaluation of the surface water quality balances (emissions-impact thresholds), and exploration of integrative measurement planning. The first results show that climate in the area is becoming warmer and drier which leads to even more dramatically shrinking water resources. Water supply is expected to be reduced between one and two thirds. Water demand might be

    Fresh fruits and vegetables are conventionally grown in raised bed plasticulture (RBP), a high intensity, high input, and high output production system. In 2016, the fresh market plasticulture industry covered 680,000 ha in the US, producing crops (e.g. tomato, peppers, melons, and strawberries) valued at ten billion dollars. To meet the increasing future demand for fresh fruits and vegetables and sustain the production potential of croplands, a transformation of the conventional food-water-energy nexus is essential. A novel agricultural conservation system, compact bed geometry, has been proposed to shift the paradigm in RBP, sustaining yield and decreasing inputs (e.g. water, nutrients, energy, and carbon). Compact bed geometries fit the shape of the wetting front created when water is applied through drip irrigation on the production soil, creating a taller (23-30 cm) and thinner bed (66-41 cm). Two seasons of tomato (single row) and pepper (double row) production, in the environmentally fragile watershed of the Florida Everglades, highlight the potential impact of compact bed geometry on environmental sustainability in agricultural production. No difference in plant growth or yield was detected, with a reduction of 5-50% in irrigation water, up to 20% less N application, 12% less P, 20% less K, and 5-15% less carbon dioxide emissions. The hydrologic benefits of compact bed geometry include 26% less runoff generation, decreased need for active drainage pumping, and increased residence time for irrigation water within the bed, overall decreasing instances of nutrient leaching. A water related co-benefit observed was a reduction in the occurrences of Phytophthora capsici in pepper, which has the potential to reduce yield by as much as 70%. Non-water co-benefits include up to a 250/ ha reduction in production cost, with the potential to save the industry 200 million dollars annually. This economic benefit has led to rapid industry adoption, with more than 20

    - The application of fallout radionuclides (FRNs) in soil erosion and redistribution studies has gained popularity since the late 1980s. In Zimbabwe, soil erosion research was mostly based on conventional methods which included the use of erosion plots for quantitative measurements and erosion models for predicting soil losses. Only limited investigation to explore the possibility of using Caesium-137 (Cs-137) has been reported in the early 1990s for undisturbed and cultivated lands in Zimbabwe. In this study, the Cs-137 technique was applied to assess the impact of soil conservation practices on soil losses and to develop strategies and support effective policies that help farmers in Zimbabwe for sustainable land management. The study was carried out at the Makoholi research station 30 km north of the Masvingo region which is located 260 km south of Harare. The area is semi-arid and the study site comprises coarse loamy sands, gleyic lixisols. The conservation agriculture (CA) practices used within the area since 1988 include (i) direct seeding (DS) with mulch, (ii) CA basins with mulch, and (iii) 18 years direct seeding, left fallow for seven years and turned into conventional tillage since 2012 (DS/F/C). The Cs-137 reference inventory was established at 214 ± 16 Bq/m2. The mean inventories for DS, CA basins and DS/F/C were 195, 190 and 214 Bq/m2 respectively. Using the conversion Mass Balance Model 2 on the Cs-137 data obtained along transects for each of the practices, gross erosion rates were found to be 7.5, 7.3 and 2.6 t/ha/yr for direct seeding, CA basins and the DS/F/C while the net erosion rates were found to be 3.8, 4.6 and 0 t/ha/yr respectively. Sediment delivery ratios were 50%, 63% and 2% in the respective order. These preliminary results showed the effectiveness of DS over CA basins in erosion control. The efficiency of fallowing in controlling excessive soil loss was significant in the plot that started as DS for 18 years but left fallow for 7

    Full Text Available This article is concerned with the adoption of small-scale irrigation farming as a climate-smart agriculture practice and its influence on household income in the Chinyanja Triangle. Chinyanja Triangle is a region that is increasingly experiencing mid-season dry spells and an increase in occurrence of drought, which is attributed largely to climate variability and change. This poses high agricultural production risks, which aggravate poverty and food insecurity. For this region, adoption of small-scale irrigation farming as a climate-smart agriculture practice is very important. Through a binary logistic and ordinary least squares regression, this article determines factors that influence the adoption of small-scale irrigation farming as a climate-smart agriculture practice and its influence on income among smallholder farmers. The results show that off-farm employment, access to irrigation equipment, access to reliable water sources and awareness of water conservation practices, such as rainwater harvesting, have a significant influence on the adoption of small-scale irrigation farming. On the other hand, the farmer’s age, distance travelled to the nearest market and nature of employment negatively influence the adoption of small-scale irrigation farming decisions. Ordinary least squares regression results showed that the adoption of small-scale irrigation farming as a climate-smart agriculture practice has a significant positive influence on agricultural income. We therefore conclude that to empower smallholder farmers to respond quickly to climate variability and change, practices that will enhance the adoption of small-scale irrigation farming in the Chinyanja Triangle are critical, as this will significantly affect agricultural income. In terms of policy, we recommend that the governments of Zambia, Malawi and Mozambique, which cover the Chinyanja Triangle, formulate policies that will enhance the adoption of sustainable small scale

    Full Text Available This article explores the possibility of incorporating traditional water management experiences into modern water management. After the literature review, two case studies are presented from Borana and Konso communities in southern Ethiopia. The study was conducted through interviews, discussions, and observations. The two cases were selected due to their long existence. Both communities have their own water source types, depending on local hydrogeological conditions. Borana is known for the so-called Ella (wells and Konso for Harta (ponds, which have been managed for more than five centuries. All government and development partners strive to achieve sustainable services in water supply and sanitation. Therefore, they design various management packages to engage the communities and keep the systems sustainable. However, the management components are often designed with little attention to local customs and traditions. The cases in the two communities show that traditional knowledge is largely ignored when replaced by modern one. However, the concepts of cost recovery, ownership experience, equity, enforcement, integrity, and unity, which are highly pronounced in modern systems, can also be found in the traditional water managements of Borana and Konso. Naturally, one shoe never fits all. Borana and Konso experiences are working for their own community. This research implies that when we plan a project or a program for a particular community, the starting point should be the indigenous practices and thoughts on life.
