  16. Orientation manual for INIS and AGRIS (OMINAS)

    International Nuclear Information System (INIS)

    The manual is intended as a basic introduction to the computerized information systems, INIS (International Nuclear Information System) and AGRIS (International Information System for the Agricultural Sciences and Technology). Both systems contain information on already published literature, and include non-conventional literature (i.e. literature not available through normal commercial channels). Full bibliographic details and a subject classification are given. INIS, in addition, supplies descriptors, data-flagged where appropriate, and abstracts with every item of literature reported. The guiding principle followed by INIS and AGRIS is one of shared responsibility in development and operation. Both input is decentralized. The collection and preparation of documents relevant to the defined subject scopes are the responsibility of the country of publication. This decentralized input is transmitted to Vienna where centralized processing, merging and dispatching take place. The main output products are two printed journals, INIS Atomindex and AGRINDEX, and magnetic tape services. The manual is divided into four parts. The first is intended as a general introduction, and gives a bird's-eye view of the principles involved in the operation of the two systems. The second and third deal with INIS and AGRIS, respectively, and offer orientation in greater depth. The last part deals with the computer aspects of the system. The manual contains several appendices, a subject index and a list of basic references

  1. Review of Agri-Environment Indexes and Stewardship Payments

    Science.gov (United States)

    Hajkowicz, Stefan; Collins, Kerry; Cattaneo, Andrea

    2009-02-01

    Agri-environment programs aim to secure environmental and social stewardship services through payments to farmers. A critical component of many agri-environment programs is an agri-environment index (AEI) used to quantify benefits and target investments. An AEI will typically comprise multiple indicators, which are weighted and combined using a utility function, to measure the benefit of investment options (e.g., projects, farms, regions). This article presents a review of AEIs with 11 case studies from agri-environment programs in the United States, Australia, and the United Kingdom. We identify a generic procedure used to define AEIs and explore the implications of alternative methodological approaches. We conclude that AEIs have become an extremely important policy instrument and make suggestions for their improvement.

  2. AGRIS: Categorization and information retrieval based on IBM's IRMS

    International Nuclear Information System (INIS)

    The subject breakdown of the AGRIS data base by categories interlinked with object and geographical codes is described. The use of these categories and codes in a mechanized information retrieval system is then considered. The system is a modification of IBM's Information Retrieval and Management System (IRMS); it allows for batch processing on an IBM/360 or /370 computer operated under OS or VS. As IRMS was developed for use with a controlled vocabulary, the search possibilities on the AGRIS files are necessarily limited. An artificial vocabulary is presented, derived from the AGRIS subject categories, object codes, geographic codes, language codes, and bibliographic data: type of record, literary indicator, volume/issue number, and the country code of the submitting centre. The use of the IRMS system for AGRIS is described, with details of programming deliberately omitted. Program descriptions with data set definitions and file formats are presented separately

  3. Solutions for Destination Management on Agri-Tourism Farm

    Full Text Available Farm tourism can be an alternative to agricultural jobs in rural communities with real agri-tourism potential. To improve destination management, we need to implement a type of management based on knowledge management. A second type of management that is a must in farm tourism is the integrated management of agri-tourism destination quality based on a code of good practices in the integrated management of quality. In order to improve agri-tourism management quality, we need to apply best management practices, i.e. 15 basic principles that contribute to the improvement of farm tourism management. These three types of management, if implemented on any agri-tourism farm, can contribute to the improvement of destination management.

    2011-01-01

    Full Text Available Problem statement: The government of Malaysia has established several agencies within the Ministry of Agriculture and agri-based Industry such as the Farmers’ Organization Authority to provide technical and motivational training to individual members involved in farming practices to become agri-entrepreneurs. Approach: The objectives of the study are to identify and determine the entrepreneurial work culture as perceived by Farmers’ Organization Authority members. Members of Farmers’ Organization Authority were interviewed via a structured questionnaire. The factor analysis determines 6 latent factors that were realized by the Farmers’ Organization Authority members as being important for promoting an entrepreneurial work culture and therefore should be enhanced and re-inculcated among the Farmers’ Organization Authority farming community. Results: These factors translate into the community having to become more innovative, responsible and accountable, profit oriented, visionary, better at performing their study practices in a more systematic way and finally to become more self confident. Conclusion/Recommendation: Efforts should be intensified to encourage Farmers’ Organization Authority members with training to focus not on modern technologies only, but on enhancing the entrepreneurial work culture and fundamental changes in attitude towards treating farming as a business. Formal entrepreneurship training should be instituted to all Farmers’ Organization Authority members who are interested in taking a loan in enhancing their farming activities. This conditionality can be implemented to ensure that the loan is being spent accordingly and the development of agri-entrepreneurship skills can be enhanced.

    Full Text Available Bhupinder Singh SekhonInstitute of Pharmaceutical Sciences, PCTE Group of Institutes, Ludhiana, IndiaAbstract: Nanotechnology is one of the most important tools in modern agriculture, and agri-food nanotechnology is anticipated to become a driving economic force in the near future. Agri-food themes focus on sustainability and protection of agriculturally produced foods, including crops for human consumption and animal feeding. Nanotechnology provides new agrochemical agents and new delivery mechanisms to improve crop productivity, and it promises to reduce pesticide use. Nanotechnology can boost agricultural production, and its applications include: 1 nanoformulations of agrochemicals for applying pesticides and fertilizers for crop improvement; 2 the application of nanosensors/nanobiosensors in crop protection for the identification of diseases and residues of agrochemicals; 3 nanodevices for the genetic manipulation of plants; 4 plant disease diagnostics; 5 animal health, animal breeding, poultry production; and 6 postharvest management. Precision farming techniques could be used to further improve crop yields but not damage soil and water, reduce nitrogen loss due to leaching and emissions, as well as enhance nutrients long-term incorporation by soil microorganisms. Nanotechnology uses include nanoparticle-mediated gene or DNA transfer in plants for the development of insect-resistant varieties, food processing and storage, nanofeed additives, and increased product shelf life. Nanotechnology promises to accelerate the development of biomass-to-fuels production technologies. Experts feel that the potential benefits of nanotechnology for agriculture, food, fisheries, and aquaculture need to be balanced against concerns for the soil, water, and environment and the occupational health of workers. Raising awareness of nanotechnology in the agri-food sector, including feed and food ingredients, intelligent packaging and quick-detection systems, is

    Full Text Available By means of quantitative and qualitative research the doctoral dissertation has attained methodical insights into competences and usage levels of new technologies for marketing purposes in agri-businesses in the Republic of Croatia. The results and observations provided in the thesis indicate that swift action is required in order to improve the current situation and prepare farmers for forthcoming changes. In biotechnical sciences there is a need for continuous updating, research and control of interdependent processes and complex relations, which in turn creates a need for a unified system of knowledge dissemination. In order to manage a set of information arising from such processes, it is necessary to have a system that will allow us to store and transfer the acquired knowledge in a safe and simple way in real time, ensuring completeness of information. In today’s world, the key role in this process is to be played by information and communication technologies (ICT encompassing the use of computers and communication technologies, as well as technologies for information management and transfer. Together with other ICT, the Internet is a resource that can bridge the gap between professionals of different expertise on one hand and people living in rural areas and farmers on the other, as it provides a platform for interaction and dialogue. Furthermore, ICT can foster new cooperation and networking through inter-sectoral contacts between government institutions, different support agencies and farmers. The efforts to implement ICT in the agricultural sector are held back by a range of limiting factors, such as: the necessity to reconstruct the sector itself, required investments in new communication systems and adjunct platforms, low levels of computer literacy among farmers, insufficient infrastructure, etc. Taking all this into account, it is obvious that the Internet and modern technologies can be drivers of positive change in agriculture

    Full Text Available In this paper we present the result of a Magnetotelluric (MT investigation carried out across the High Agri Valley (HAV, southern Italy. Several MT soundings were carried out in order to obtain a ~15 km long 2-D resistivity model with an investigation depth of ~10 km. The main aim was to provide valuable data on the geological and structural setting of the HAV. The MT model was compared with pre-existing geological, geophysical and seismic data. The MT model can be schematized as a superposition of three stack lateral varying layers with different thickness and resistivity values: a surficial low-medium resistivity layer, associated to the Quaternary deposits and to the allochthonous units, and a deeper high resistivity layer, related to the Apulia Platform, separated by a thin layer connected to the mélange zone and to the Pliocene terrigenous marine deposits. Sharp lateral resistivity variations are interpreted as faults that, on the basis of accurate focal mechanism computations, display normal-faulting kinematics.

  16. Agri-environmental collaboratives as bridging organisations in landscape management.

    Science.gov (United States)

    Prager, Katrin

    2015-09-15

    In recent years, landscape and its management has become a focus of policies and academic conceptualisation. Landscape is understood as a concept of interconnected natural and human systems. Its management must take into account the dynamic interdependencies and diverging interests of various stakeholders at different levels. Bridging organisations can provide an arena for trust-building, conflict resolution, learning and collaboration between relevant stakeholders. This paper draws on two strands of literature - landscape governance and co-management of social-ecological systems - to investigate the contributions of agri-environmental collaboratives (AEC) to sustainable landscape management. Based on data from 41 interviews with key informants and AEC members in Germany and the Netherlands, six fields of contributions were identified: policy implementation and service provision; coordination and mediation; awareness raising and behaviour change; care for 'everyday' landscapes; maintenance and protection of landscapes (including species and habitats); and income generation and economic benefits. Some of the contributions evolve around the specific role of AEC as bridging organisations, but other contributions such as economic benefits emerge beyond this analytical lens. The paper therefore emphasises holistic, bottom up assessment of AEC contributions and argues that governments should support such organisations through i) funding for facilitators and ii) funding for impact monitoring and data management.

    2015-05-01

    Full Text Available During the last few years, the definition of sustainability and the translation of its general principles into practical and operative tasks have come into the foreground of scientific research and political agendas throughout the world. The understanding and the evaluation of the environmental, social and economic performances of complex agricultural food systems is probably the real challenge, and the design of more sustainable alternatives has been recognized as necessary for a correct territorial management. This study’s primary goal is the proposition of an interpretive structure “Sustainable Agri-Food Evaluation Methodology” (SAEMETH, able to guide the evaluation of the sustainability of the various organizational forms of the small-scale agri-food supply chain. As a case study, the methodology was applied to 10 small-scale agri-food systems. The application of SAEMETH, as a monitoring tool based on qualitative indicators that are user-friendly and strongly communicative, demonstrates that it is possible to carry out sustainability evaluations of the small-scale agri-food systems through a long-term approach that is participatory, interdisciplinary and multi-institutional and that integrates a solid theoretical base with an operative framework tested in the field. SAEMETH can, in this way, generate a cyclical process that increases the probability of success in the design of sustainable alternatives and the implementation of projects and initiatives at the local/regional scale.

    Directory of Open Access Journals (Sweden)

    Tuzon Troy P.

    2014-01-01

    Full Text Available The study was conducted to determine the acceptability of the residents of Barangay Casile, Cabuyao, Laguna, Philippines in transforming their locality into an eco-agri tourism site. A total of 241 residents participated in the data collection using a survey questionnaire and interviews. Barangay Casile is an agricultural area and is also noted for its natural heritage such as the Matang Tubig River and Falls and the Marcos Twin Tower. Because of this, the local government unit of Cabuyao City plans to develop the area as a nature- based tourism destination specifically as an eco-agri tourism site. The survey revealed that the respondents agreed on the proposition of transforming their area into agri-tourism site. Cultural acceptability ranks the highest which means that the locals are open on the possible effects on their culture that the development could bring them. Economic and social acceptability were also ranked high because of the income they could get from the influx of tourists. Environmental acceptability is the least agreeable because most of the respondents were environment sensitive and are concerned with the changes to the natural façade of their area. It can be concluded that agri-tourism development involving local residents provides control over the development and management of the project.

    2011-01-01

    In the south-eastern depocentre of the Val d'Agri basin (Southern Apennines), a volcanic ash layer crops out interbedded within poorly structured alluvial fan deposits of Late Pleistocene age. Textural, depositional and pedological features of this weathered layer suggest a primary deposition from a pyroclastic fall-out of volcanic ash. Chemical analyses of feldspars show an alkali trachytic composition and accessory minerals association allow to correlate this tephra layer with the regionally dispersed Y-7 marine tephra layer (Tufo Verde Epomeo eruption, Ischia volcano), dated at 56 ± 4 ka. The Val d'Agri tephra here described for the first time was deposited during MIS Stage 3. Its recovery and characterization permit to contribute to regional correlation of the Mediterranean climatic and volcanic events from marine to continental successions and to describe landscape evolution of the Southern Apennines during glacial-interglacial cycles.

    Full Text Available The supply chain of agricultural products has received a great deal of attention lately due to issues related to public health. Something that has become apparent is that in the near future the design and operation of agricultural supply chains will be subject to more stringent regulations and closer monitoring, in particular those for products destined for human consumption (agri-foods. This work is concerned with the planning of a real agri-food supply chain for chicken meat for the city of Tlemcen in Algria. The agri-food supply chain network design is a critical planning problem for reducing the cost of the chain. More precisely the problem is to redesign the existing supply chain and to optimize the distribution planning. As mentioned in our paper, the entire problem is decomposed into two problems, and each problem is solved in sequential manner, to get the final solution. LINGO optimization solver (12.0 has been used to get the solution to the problem.

    2015-08-01

    Full Text Available Today, the global business environment compels enterprises to consider rest of the world in their competitive strategy analysis where firms ignore external factors such as economic trends, competitive positions or technology advancement in other countries. While going truly global with supply chain management, a company develops product in the United States, produce in India and trade in Europe, and they have changed the traditional operation management & logistical activities. This change in trade and the modernization of transport infrastructures have elevated the importance of flow management to new levels. Manufacturers and researchers have noticed many problems concerning supply chain activities, and usually either a system or subcomponent in supply chains is discussed in the literature, but they fails to answer the rational (why, what, how behind them. This paper addresses a review of the principles, bottlenecks and strategies of supply chain practices for organizations with an emphasis on the implications of Indian agri-food sector. Findings of this review reveal that the human & environmental issues, improved product visibility, food safety/quality and the associated economic benefits in sustainable agri-food supply chains can be achieved through innovation, collaboration, elimination of uncertainties and introducing global SCM practices into green & lean initiatives.

  8. Optimizing environmental measures for landscape multifunctionality: effectiveness, efficiency and recommendations for agri-environmental programs.

    Galler, Carolin; von Haaren, Christina; Albert, Christian

    2015-03-15

    Agri-environmental measures differ in their capacity to simultaneously enhance the provision of multiple ecosystem services. Multifunctional approaches are hampered by funding schemes that are usually administered by individual administrative sectors that each predominantly focus on one single environmental objective. Developing integrative management strategies that exploit synergies from implementing multifunctional measures is challenged by the need to quantify expected management effects on different ecosystem services. The objective of this paper is to compare uncoordinated versus coordinated management strategies in their contribution to multiple environmental objectives. We developed and applied a method for quantifying effectiveness, as well as spatial and cost efficiency with respect to four key landscape functions: erosion prevention, water quality conservation, climate change mitigation and safeguarding biodiversity. The case study area was the county of Verden, Germany. The following findings can be drawn: Measures for safeguarding biodiversity and climate change mitigation have generally high multifunctional effects, which makes them suitable for integrative management strategies. To make use of the added value of potential multifunctional measures, a spatially targeted allocation of agri-environmental measures is necessary. Compared to uncoordinated strategies, coordinated integrative management strategies either allow the optimization of the ratio of costs to environmental effects or an increase in the effects that can be achieved within an area unit. This is however, usually not simultaneous. Future research should seek to refine the assessment and valuation indicators. PMID:25577703

    Aiming at the pricing of primary agricultural products for the large-scale suppliers and the wholesalers in agri-supply chain management, an approach for the large-scale supplier pricing is presented based on the threshold cointegration method of wholesale prices online including the GBand-TAR modified Band-TAR model. Our empirical work shows that it is more appropriate for a large-scale supplier pricing with his wholesalers based on the threshold cointegration method than the conventional linear cointegratiun method in spatially separate markets in an agri-supply chain of soybean in China in short time. Firstly, the three pairs of prices in spatially separate markets are of long-run equilibrium and threshold cointcgration. The forecast lest shows that the thresh-old cointegration approach is superior to the conventional linear cointegration approach in short time. Secondly, there are two thresholds of GBand-TAR in which the threshuht parameters represent relative transaction costs. Larger thresholds or wider neutral band corresponds to the greater distance between markets. Thirdly, the esti-mation of M-TAR shows that the large-scale supplier is more sensitive to incrcase of wholesaler prices than de-crease of wholesaler prices. The supplier can price on the forecast of market price by the threshold ECM inclu-ding the GBand-TAR if the equilibrium error of threshold lag is not in the interval of thresholds in which there is not profitable trading opportunities for the supplier.

    In the mid 1970s, the available RMs, notably Bowen's Kale and Orchard Leaves and Bovine liver from National Bureau of Standards (NBS), although of great benefit, were overwhelmingly insufficiently representative, in respect of matrix and elemental composition, of the wide range of natural products submitted for analysis and in worldwide commerce. To provide additional coverage, an RM development project was initiated with input from cooperating analysts leading to an Agriculture and Agri-Food Canada/National Institute of Standards and Technology (NIST) cooperative venture and development of a total of 12 different agricultural/food RMs. With a total of 303 concentration values for 34 elements and a wide range of matrix components such as ash, silica, protein, fat, carbohydrate and fiber, these RMs significantly augment the world repertoire of biological control materials. A final material under consideration is a highly reliable, discrete, synthetic RM for quality control and calibration. This paper summarizes the research and developmental activities undertaken during the past quarter of a century related to RM development at Agriculture and Agri-Food Canada and includes a short historical background, conceptual considerations, preparation, physical characterization, homogeneity estimation, chemical characterization, calculation of recommended reference values and associated uncertainties, methodology development and application, and performance of inorganic analytical methods in a multielement, multilaboratory, collaborative characterization campaign.

  11. The Symbiotic Food System: An ‘Alternative’ Agri-Food System Already Working at Scale

    Directory of Open Access Journals (Sweden)

    2016-08-01

    Full Text Available This article is an analysis of the agri-food system that feeds most of the over four million residents of the fast growing city of Dar es Salaam in Tanzania. It is based on qualitative research that has traced the sources of some important foods from urban eaters back through retailers, processors and transporters to the primary producers. Particular attention is given to the functioning of the market places and how new actors enter into the food system. These reveal that more important to the system than competition are various forms of collaboration. Of particular interest is how a wide range of small-scale and interdependent actors produce the food and get it to urban eaters at a city feeding scale without large vertically- or horizontally-integrated corporate structures. This “symbiotic food system” is an existing alternative to the corporate-dominated agri-business food system; it can and does deliver at scale and in a way that better responds to the needs of people in poverty who are buying food and the interests of food producers. It is not perfect in Dar es Salaam, but the food system is working and is a model that should be built on.

    Since the 90s, in Europe the Common Agricultural Policy (CAP) started to activate measures for improving the sustainability of European agriculture, these measures were systematized in 2000 with the tools of rural development, pursuing a synergistic environmental action trough the agri-environmental payments. Since their definition, those payments were designed to ensure the protection, maintenance and enhancement of natural resources (water, soil, forests), biodiversity (species and habitat), and landscape. In particular initiatives as set aside, afforestation, organic agriculture, integrated pest management, low input and precision agriculture have enriched the agricultural management practices. The aim of this work is to check the trend between agro-environmental subsidies and environmental performance (based on Ecological Indicators and CO2 evaluation) at country level in EU, in order to study the regulatory framework impact in addressing the European cropping system towards sustainability. In particular soils and their land use can storage CO2 as pool and so provide environmental services and, on the other hand the agricultural practices can stimulate the emission and the environmental footprint. Impacts (so called emissions/footprints and storage/environmental services) will be compared with the Agri-environmental Payments for calculating performances due to environmental management practices, supported by political initiatives. Such analysis sustains the European policy makers towards more suitable agricultural policies and in particular it can address national sustainability through agricultural practices.

    Full Text Available Preserving our landscape in sustainable development processes is now widely considered as fundamental. It is a complex and evolving issue that can be tackled from several perspectives. Agronomy can contribute to analyzing the relationships between agricultural production systems (cropping, farming and agricultural systems at different levels (field, farm, and region and the agricultural landscape (in terms of patches, matrixes, dynamics, etc. This is of particular interest where the relationships between “what and how” are produced by agricultural activities and the landscape are changing. In this case their own reciprocity may represent an opportunity to analyze complex systems, such as the characterization of agri-landscapes at a regional level. We propose a case study developed as an up-scaling analytical process from a farm to a regional level. The result was the identification of six main agri-landscape systems highlighting the landscape drivers that are changing the traditional landscape of a rural region in Northern Tuscany (Lunigiana.

  14. Recent Developments in Indicators and Models for Agri-environmental Assessment

    Full Text Available Over the years there has been a remarkable development in agricultural and environmental sciences and the public is growing increasingly concerned about the relations between agriculture and the environment, and about the sustainability of agricultural production systems in many parts of the world. Policy makers and the general public have asked the scientific community to make more information available, and a great wealth of research studies have been conducted and published in recent years. Many studies include in-depth analyses of agricultural systems based on simulation models for various purposes: understanding the mechanisms involved, comparing alternative scenarios and supporting and evaluating policy measures. Indicators are also frequently used to provide concise quantitative figures of various aspects (economic or productive performances, environmental impacts, etc. and to communicate them to a broad audience. This paper offers a survey of the recent literature dealing with agri-environmental issues and, in particular, of those references presenting the use of models and indicators for the assessment of agricultural systems and their effects on environmental compartments (water, soil, air, from multiple disciplinary perspectives, and at various scales. The references examined for this paper have been classified in order to group the papers according to various criteria, thus facilitating the identification of relevant references, and to compare their contents. The methodological approaches are analysed and compared in order to highlight the contributions of the scientific literature to the assessment of agro-ecosystems and agri-environmental policies.

    Full Text Available This study seeks to analyze the benefits, as well as the likely risks of cultivating Jatropha curcas in small production units of rain fed lands in Yucatán. In order to analyze the possible development of local artisanal agri-industry in the context of policies related to biofuels in Mexico, interviews with key informants were made to identify the agricultural potential of Jatropha c. in monoculture and associated crops. Its cultivation and using for biodiesel in the country will be possible as long as it not implies competition with crops for family consumption and it not represents an environmental degradation factor. Production of Jatropha c. on small areas could be a productive choice if public policies are established to promote biodiesel production and its use in national industry.

    2007-04-01

    Full Text Available The comparative analysis of trade with agricultural and food products of ten EU new member states (NMS, with emphasis on Slovenia, has been conducted at a highly disaggregated level. Slovenia has always been the net importer of agricultural and food products, and the same goes for the majority of ten NMS in the period analysed. For the purpose of assessing the similarities in their export structure, the export similarity index “S” has been used. By its use no significant overlap of export structures between NMS is revealed, but the slightly increase in resemblance is observed from 1999 to 2003, indicating the simultaneous restructuring of NMS’ agri-food sectors. Another indicator introduced in this comparative analysis is Revealed Comparative Advantage “RCA”, measuring competitiveness through major groups of products. Slovenia has the comparative advantage in comparison with the rest of new member states in following groups of products: meat, dairy products, beverages and others.

    Severe situation faced by China’s agri-ecological security is elaborated.It is believed that cultivation of farmers’ citizenship is the key to solving this problem,because it is favorable to consolidating farmers’ independent and equal ideas,enhancing farmers’ cooperative community idea,cultivating farmers’ concept of rule by law,and strengthening farmers’ fair and just moral concept.It is expected to make farmers fully exercise their civil rights and consciously perform their civil responsibilities.Finally,practical paths for cultivation of farmers’ citizenship are put forward.These include improving market economy to promote equality of subjects,carrying out democratic practice to stimulate public participation,prospering cultural education to make clear public liability,propagating law in villages to carry forward spirit of rule by law,and making definite government responsibility to encourage social supervision.

  12. DNA markers as a tool for genetic traceability of primary product in agri-food chains

    Directory of Open Access Journals (Sweden)

    Daria Scarano

    2012-11-01

    Full Text Available The agri-food components of the Made in Italy are well known all over the world, therefore they may significantly contribute to the Italian economy. However, also owing to a large number of cases of improper labelling, the Italian agro-food industry faces an ever-increasing competition. For this reason, there is a decline of consumers’ confidence towards food production systems and safety controls. To prevent erroneous classification of products and to protect consumers from false instore information, it is important to develop and validate techniques that are able to detect mislabelling at any stage of the food-chain. This paper describes some examples of genetic traceability of primary products in some important plant food chains such as durum wheat, olive and tomato, based on DNA analysis both of raw material and of processed food (pasta, olive oil, and peeled tomato.

  13. Multi-scale electromagnetic imaging of the Monte Aquila Fault (Agri Valley, Southern Italy)

    The Agri Valley is a NW-SE trending intermontane basin formed during the Quaternary times along the axial zone of the Southern Apennines thrust belt chain. This basin is about 30 Km long and 12 Km wide and is filled by Quaternary continental deposits, which cover down-thrown pre-Quaternary rocks of the Apennines chain. The Agri Valley was hit by the M 7.0, 1857 Basilicata earthquake (Branno et al., 1985), whose macroseismic field covered a wide sector of the Southern Apennines chain. The latest indications of Late Quaternary faulting processes in Agri Valley were reported in Maschio et al., (2005), which documented a unknown NE-dipping normal fault thanks to the finding of small-scale morphological features of recent tectonic activity. The identified structure was termed Monte Aquila Fault (MAF) and corresponds to the southern strand of the NW-SE trending Monti della Maddalena Fault System (Maschio et al., 2005; Burrato and Valensise, 2007). The NE-dipping MAF consists of a main northern segment, about 10 Km long, and two smaller segments with cumulate length of ~10 Km, thus bringing the total length to ~20 Km. The three segments are arranged in a right-stepping en-echelon pattern and are characterized by subtle geomorphic features. In order to provide more detailed and accurate information about the MAF, a strategy based on the application of complementary investigation tools was employed. In particular, multi-scale electromagnetic investigation, including Electrical Resistivity Tomography (ERT), Ground Penetrating Radar (GPR) and Magnetotelluric (MT) methods, was used to image the MAF from near-surface to several hundred metres depth. Large-scale MT investigation proved to be useful in detecting the MAF location down to several hundred meters depth, but it didn't show any shallow evidence about MAF. Conversely, ERT and GPR surveys evidenced signatures of normal-faulting activity at shallow depth (e.g., back-tilting of the bedrock, colluvial wedges, etc.). In

    Full Text Available Agricultural activities within city boundaries have a long history in both developed and developing countries. In this paper, a broad approach to Urban AgriCulture (UAC is used, one that includes the production of crops in urban and peri-urban areas and ranges in developed countries from allotment gardens over community gardens to semi-entrepreneurial self-harvest farms and fully commercialized agriculture. With an empirical case study on UAC Initiatives in the Bonn/Rhein-Sieg region this work fills a gap since the lack of comprehensive and comparative studies on urban agriculture (UA currently makes it difficult for researchers to identify the benefits of UA activities.

    The claim has often been made that nanotechnologies will contribute to the global development process. In 2005, a careful study identified specific areas where nanotechnologies could help developing countries achieve the millennium development goals. This article examines whether the research agenda of nanotechnology in the intervening period, as reflected in publications, has followed the directions identified at that time, in three key areas, water, energy, and agri-food. We find that the research community has taken up the broad directions indicated in the earlier study, although not so often the detailed applications of specific nanoscale techniques or phenomena. However, the impact on global development is unclear, both because the same applications can be useful in both developed and developing countries, and because the conditions in developing countries may not match the socio-technical requirements of the applications.

  16. Stakeholder involvement in agri-environmental policy making--learning from a local- and a state-level approach in Germany.

    Prager, Katrin; Freese, Jan

    2009-02-01

    Recent European regulations for rural development emphasise the requirement to involve stakeholder groups and other appropriate bodies in the policy-making process. This paper presents two cases involving stakeholder participation in agri-environmental development and policy making, targeted at different policy-making levels. One study was undertaken in Lower Saxony where a local partnership developed and tested an agri-environmental prescription, which was later included in the state's menu of agri-environmental schemes. In Sachsen-Anhalt, state-facilitated stakeholder workshops including a mathematical model were used to optimise the programme planning and budget allocation at the state level. Both studies aimed at improving the acceptance of agri-environmental schemes. The authors gauge the effectiveness of the two approaches and discuss what lessons can be learned. The experience suggests that the approaches can complement one another and could also be applied to rural policy making. PMID:18632199

    Changes in agricultural practice across Europe and North America have been associated with range contractions and local extinction of bumblebees (Bombus spp.). A number of agri-environment schemes have been implemented to halt and reverse these declines, predominantly revolving around the provision of additional forage plants. Although it has been demonstrated that these schemes can attract substantial numbers of foraging bumblebees, it remains unclear to what extent they actually increase bumblebee populations. We used standardized transect walks and molecular techniques to compare the size of bumblebee populations between Higher Level Stewardship (HLS) farms implementing pollinator-friendly schemes and Entry Level Stewardship (ELS) control farms. Bumblebee abundance on the transect walks was significantly higher on HLS farms than ELS farms. Molecular analysis suggested maximum foraging ranges of 566 m for Bombus hortorum, 714 m for B. lapidarius, 363 m for B. pascuorum and 799 m for B. terrestris. Substantial differences in maximum foraging range were found within bumblebee species between farm types. Accounting for foraging range differences, B. hortorum (47 vs 13 nests/km(2) ) and B. lapidarius (45 vs 22 nests/km(2) ) were found to nest at significantly greater densities on HLS farms than ELS farms. There were no significant differences between farm type for B. terrestris (88 vs 38 nests/km(2) ) and B. pascuorum (32 vs 39 nests/km(2) ). Across all bumblebee species, HLS management had a significantly positive effect on bumblebee nest density. These results show that targeted agri-environment schemes that increase the availability of suitable forage can significantly increase the size of wild bumblebee populations.

    Full Text Available The growth of tourism in the Philippines can be largely attributed to nature-based destinations but communities in these areas largely depend on farming and fishing to sustain their day-to-day needs.  The need to capacitate the community’s social and human capital in addressing climate change impacts to their livelihood, properties and natural environment is deemed necessary to lessen their vulnerability issues in the management of agriecotourism destinations. The study aimed to 1. characterize and rank hazards that are likely to affect the nature-based tourism communities, 2. describe the nature-based tourism communities’ current sensitivity and exposure to climate stresses; and 3. estimate future vulnerability and risks of nature-based tourism communities.  Three agri-ecotourism communities were selected using five criteria such as attraction uniqueness, hazard type, risk level, tourism dependency and market potential.  The areas were subjected to tourism vulnerability case assessment focusing on services and energy; human health; food, security, water and agriculture; business and continuity; and biodiversity and culture.   Calaguas Island’s top hazards are typhoon, drought and strong wind.  Pecuaria Farm’s main hazards are drought, rat infestation and grass fire while Bulusan Lake’s major hazards are heavy rains and ash falls brought by volcanic eruption.  Generally, vulnerability is high in the human health, services and energy sectors of tourism. The vulnerability of the three agri-ecotourism sites was intensified by factors that merely characterize the kind of community they have: a high marketing dependency, b poor political will, c low level of awareness and preparedness, d poor farming practices and e lack of tourism-related livelihood options. Destinations with functioning agricultural areas are the most affected sites due to an estimated increase in the temperature and increase in rainfall precipitations.  Poverty

    Knowledge synthesis refers to the integration of findings from individual research studies on a given topic or question into the global knowledge base. The application of knowledge synthesis methods, particularly systematic reviews and meta-analysis, has increased considerably in the agri-food public health sector over the past decade and this trend is expected to continue. The objectives of our review were: (1) to describe the most promising knowledge synthesis methods and their applicability in agri-food public health, and (2) to summarize the recent advancements, challenges, and opportunities in the use of systematic review and meta-analysis methods in this sector. We performed a structured review of knowledge synthesis literature from various disciplines to address the first objective, and used comprehensive insights and experiences in applying these methods in the agri-food public health sector to inform the second objective. We describe five knowledge synthesis methods that can be used to address various agri-food public health questions or topics under different conditions and contexts. Scoping reviews describe the main characteristics and knowledge gaps in a broad research field and can be used to evaluate opportunities for prioritizing focused questions for related systematic reviews. Structured rapid reviews are streamlined systematic reviews conducted within a short timeframe to inform urgent decision-making. Mixed-method and qualitative reviews synthesize diverse sources of contextual knowledge (e.g. socio-cognitive, economic, and feasibility considerations). Systematic reviews are a structured and transparent method used to summarize and synthesize literature on a clearly-defined question, and meta-analysis is the statistical combination of data from multiple individual studies. We briefly describe and discuss key advancements in the use of systematic reviews and meta-analysis, including: risk-of-bias assessments; an overall quality

    Agricultural producers in the Podkarpackie voivodeship are seeking new opportunities and they see a chance for the development of their farms also in agri-environmental program. Survey research has shown that the majority of the farmers decided to participate in the agri-environmental actions for economic reasons and in the extent of their knowledge and the way in which they perceive environmental issues do not differ much from the surveyed parties who do not carry out agrienvironmental program. Even thought they composted organic waste, do not dispose them in the illegal dumpsites and they claim (98% that they comply with the Code of Good Agricultural Practice (while in the group who do not realize the program that answer was provided only by 20% of the respondents, they did not recognize the threat to the environment due to the deterioration of biodiversity.

  4. Chain-wide consequences of transaction risks and their contractual solutions : managing interdependencies in differentiated agri-food supply chains

    OpenAIRE

    Wever, M.

    2012-01-01

    Agri-food supply chains are characterized by strong interdependencies between the different stages. These interdependencies may lead to risk-spillovers, as when a downstream company is exposed to risks resulting from activities further upstream in the supply chain. For example, a change in the formula used to calculate the price in a farmer-processor transaction, may reduce incentives for farmers to produce high quality products. This can increase the risks that low quality products are excha...

    2011-01-01

    Public policy regarding innovation in the Canadian value-added agri-food sector does not appear to meet its intended outcomes. Rather than being a commodity producing nation, Canada has attempted to focus its attention on adding value to products that increase economic returns. Innovation capacity and ability to capture opportunities appear to be limiting factors. This research therefore conducted a general review of the food system in Canada with a specific focus on innovation in the fun...

    Nanotechnology has the potential to innovate the agricultural, feed and food sectors (hereinafter referred to as agri/feed/food). Applications that are marketed already include nano-encapsulated agrochemicals or nutrients, antimicrobial nanoparticles and active and intelligent food packaging. Many nano-enabled products are currently under research and development, and may enter the market in the near future. As for any other regulated product, applicants applying for market approval have to demonstrate the safe use of such new products without posing undue safety risks to the consumer and the environment. Several countries all over the world have been active in examining the appropriateness of their regulatory frameworks for dealing with nanotechnologies. As a consequence of this, different approaches have been taken in regulating nano-based products in agri/feed/food. The EU, along with Switzerland, were identified to be the only world region where nano-specific provisions have been incorporated in existing legislation, while in other regions nanomaterials are regulated more implicitly by mainly building on guidance for industry. This paper presents an overview and discusses the state of the art of different regulatory measures for nanomaterials in agri/feed/food, including legislation and guidance for safety assessment in EU and non-EU countries.

    Full Text Available A PM1 (i.e., aerosol particles with aerodynamic diameter less 1.0 μm short term monitoring campaign was carried out in Agri Valley (southern Italy in September 2012. This area is of international concern since it houses the largest European on-shore reservoir and the largest oil/gas pre-treatment plant (i.e., Centro Olio Val d'Agri – COVA within an anthropized context. PM1 measurements were performed in Viggiano, the nearest town to the COVA plant and one of the most populated town of the Agri Valley. During the study period, the PM1 daily concentrations ranged from 1.2 to 8.4 μg m−3 with a mean value of 4.6 μg m−3. Regarding the PM1 chemical composition, it can be observed that S and typical crustal elements were the most abundant constituents of the PM1 collected. By applying the Principal Component Analysis, it was pointed out that crustal soil, biomass and wood burning, secondary atmospheric reactions involving COVA plant emissions and local soil particles, and traffic were the main sources contributing to the PM1 measured in the area under study. Moreover, a possible contribution of the long-range transport of African dust was observed.

    2015-08-01

    Full Text Available Over the past twenty years, agricultural biotechnologies have generated chronically unresolved political controversies. The standard tool of risk assessment has proven to be highly limited in its ability to address the panoply of concerns that exist about these hybrid techno/organisms. It has also failed to account for both the conceptual and material networks of relations agricultural biotechnologies require, create and/or perform. This paper takes as a starting point that agricultural biotechnologies cannot be usefully assessed as isolated technological entities but need to be evaluated within the context of the broader socio-ecological system that they embody and engender. The paper then explores, compares and contrasts some of the methodological tools available for advancing this systems-based perspective. The article concludes by outlining a new synthesis approach of comparative cartographies of agri/cultures generated through multi-sited ethnographic case-studies, which is proposed as a way to generate system maps and enable the comparison of genetically modified (GM food with both conventional and alternative agri-food networks for sustainability assessment. The paper aims to make a unique theoretical and methodological contribution by advancing a systems-based approach to conceptualising and assessing genetically modified organisms (GMOs and proposing a synthesised methodology for mapping networks of relations across different agri/cultures.

    2015-05-01

    Full Text Available Most studies of Localised Agri-Food Systems (LAFS focus on the localised concentration of members and firms, and pay less attention to organisational factors, particularly those of an exogenous nature. This paper focuses on the role of organisation in a LAFS, assessing the efficacy of EU organisational measures aimed at strengthening the concentration of supply from the recent CAP reform 2014-2020. The paper has three sections. Part One describes the evolution of the concept of LAFS. Part Two examines the leading role played by institutions in organising relationships between firms in a LAFS. The example provided is that of the measures affecting the organisation of supply introduced by the recent CAP reform, 2014-2020. It makes particular reference to the Distretto del pomodoro da industria – Nord Italia (‘Industrial Tomato District – Northern Italy’. Part Three describes how organisational factors can lead to the creation of a LAFS, while the criterion of proximity is necessary but not sufficient.

    2013-08-01

    Full Text Available Intercropping of agricultural crops with woody species is an age-old practice in traditional farming systems in the tropics. Food production is the major aim of subsistence farmers with most of their farmland being allocated to food crops rather than to trees and shrubs. Due to increasing population and scarcity of productive lands that cannot sustain intensive exploitation, one method that has been proposed to enhance the sustainability of agricultural production is the growing of trees in association with crops. Alley cropping is an agroforestry system in which food crops are grown in alleys formed by hedge rows of trees or shrubs and these hedge rows are kept pruned during the rainy season. The hedge rows are usually cut to a height of about 2 m when crops are sown and kept pruned to reduce competition with crops. Work done on alley cropping in Pongamia pinnata was less in India and other countries. Hence literature pertaining to tree crop competition studies in agri-silvi system was presented in this chapter. Moreover, it was unable to get sizeable literature related to speciality corn. In view of the paucity of adequate literature related to speciality corn, few citations with respect to grain corn were also presented in brief to know the general scientific idea.

    2011-02-01

    Full Text Available The aim of this work is to analyse the role that typical products can play in the local development process. Territorial resources involved, limits and strategies for their enhancement are analysed; this analysis will permit both to define the results that have been achieved since nowadays in the local development process and to point out future themes for the research in the field of agricultural economics. The typicality of an agri-food product regards qualitative characteristics that derive from its tie with the territory, this tie becomes a relevant element for the differentiation of the typical product from the others. In this context, the typical product maintains all the specificities associated to its origin, involving also aspects related to the traditions and the culture of the territories, to the collective dimension and to the local knowledge. Consumers tent to look for good which are differentiated and to connect authenticity and local specificity of food with healthiness. Due to the strong socio-economic ties that typical products have with the territory, they play a crucial role in the economy of the local systems and can promote development in lagging areas.

    2001-01-01

    Agriculture has been central to accounts of Thailand's modernisation and the rise of the national development project between the 1940s and the 1970s. However, the role of agriculture in the waning of national development is rarely explored critically in the Thai context. This paper focuses on agriculture and the role of the state in the shift from national development to globalisation. The first part of the paper examines the beginnings of Thailand's modern agricultural sector, before turning to the state-sponsored diversification of agriculture in the 1950s. The paper locates shifting state responses to agriculture in the late 1950s and 1960s in the context of specific political and historical social forces, before exploring the emergence of agri-food exports in the 1970s and the rise of agribusiness in the 1980s and 1990s. The paper concludes by commenting on the significance of the Thai state's role in the national development project and the globalisation project.

    In the frame of a national project funded by Eni S.p.A. and developed by three institutes of the National Research Council (the Institute of Methodologies for Environmental Analysis, the Institute of Research for Hydrogeological Protection and the Institute for Electromagnetic Sensing of the Environment), a multidisciplinary approach based on the integration of satellite, aero-photogrammetric and in situ geophysical techniques was applied to investigate an area located in the Montemurro territory in the southeastern sector of the High Agri Valley (Basilicata Region, southern Italy). This paper reports the results obtained by the joint analysis of in situ geophysical surveys, aerial photos interpretation, morphotectonic investigation, geological field survey and borehole data. The joint analysis of different data allowed us (1) to show the shallow geological and structural setting, (2) to detect the geometry of the different lithological units and their mechanical and dynamical properties, (3) to image a previously unmapped fault beneath suspected scarps/warps and (4) to characterize the geometry of an active landslide affecting the study area.

    The evaluation of the economic damage caused by soil erosion assumes great importance. It serves to increase awareness of the problem among farmers and policy makers. Moreover, it can promote the implementation of conservative measures at the field and basin level by spurring the development of more sustainable soil management practices. In the present study we have developed a new approach to evaluate the incentive for the adoption of Agri-Environment Measure (AEM) in Mediterranean degraded and eroded vineyards. In order to estimate this incentive, the replacement cost and the loss of income are calculated under two different soil management such as Conventional Tillage (CT) and Cover crop (AEM). Our findings show that the incentive could range between the loss of income due to AEM adoption and ecosystem service benefit (RCCT - RC AEM). In the case of study the incentive ranged between 315 € ha-1 (loss of income) and 1,087.86 € ha-1 (Ecosystem service benefit). Within this range, the incentive amount is determined according to efficiency criteria taking into account the morphological conditions of the territory in which operate the farms. Moreover, a conceptual model on the public spending efficiency has been developed to allocate the incentives where the economic return in term of ecosystem service is higher.

In terms of WTO definition, this means benefits other than commerce and food production such as environmental protection, landscape preservation, rural employment, and food security. Due to specific natural conditions and human activities, agri-cultural heritage sites always have fragile ecological environments, rich cultures, undeveloped economies and multi-functionality. This implies that agri-cultural heritage sites have production, ecological, cultural and other functions. The concept of multi-functionality has triggered discussions on agri-cultural heritage systems in China and abroad. There are not only so lots of agri

    Full Text Available Agriculture is a global issue nowadays. At the European level, it is a sector, in which we are investing many resources. In particular, the Agri-Food sector plays a central role in the policies of the European Commission and the Horizon 2020 research and innovation program, as well as being the main theme of Expo 2015 that will be held in Milan, Lombardy. In the Lombardy region, the farmers represent 2% of the entire population, cultivating about 80% of the agricultural land. Increasing needs to develop a common body of knowledge shared at the regional and national level so as to make it possible to effectively monitor cropping systems, water stress and impacts of climate changes affecting more frequently the territory, are becoming more and more urgent. In this context, the project Space4Agri (S4A intends to support the regional and local needs in terms of management of the agriculture sector, by designing and developing an information and knowledge based platform for managing geospatial and mainstream information by making it accessible over the Internet by standard communication technologies (Geo&Mainstream ICT. This platform has been designed to allow data workflows integrating i spatial data and observations, ii non-spatial information available from existing agronomic databases, iii data collected in the field by farmers, agronomists and volunteers using mobile applications, iv data collected by unmanned aerial sensors, and/or data produced by researchers as a result of applying scientific analysis on high quality remote sensing data. Foreseen results of the Space4Agri project and from other similar ongoing research activities may significantly spur the socio-economic development of Europe and create new growth opportunities for companies, public administrations, students and citizens.

    2014-12-01

    Full Text Available New and alternative models for agri-food production and consumption have brought up questions regarding the effects they have on local development processes in terms of the economic exploitation of rural areas as well as environmental, cultural, and social factors. The agri-food system proposed by the Slow Food (SF Presidia Project, which focuses on farm-to-market systems for local, high-quality, sustainable products, can respond to the new and emerging needs of both rural and urban populaces via several approaches in addition to food production itself. However, evaluating these parameters is challenging. The aim of this study was to develop an indicator-based tool to monitor the sustainability in agri-food systems that considers quality as well as economic, ecological, social, and cultural aspects. We: (i translated the major SF principles of "good," "clean," and "fair" into five major criteria to evaluate sustainability; (ii designed multiple indicators to monitor progress toward sustainability for each of those criteria; and (iii applied the monitoring tools to three case studies as a first attempt at end-use validation. Indicators and criteria were weighted either equally or based on their importance to surveyed stakeholders, i.e., consumers, producers, and scientists/experts. The proposed approach performed well as a tool for a broad sustainability evaluation by effectively combining the indicators with the same feedback. With this approach, we demonstrated that the SF Presidia project increases all dimensions of sustainability and in particular socioeconomic and cultural capital by preserving the environmental and quality aspects of the food products.

    Full Text Available One of the main concerns of the environmental scientists and policy makers is related to the environmental compatibility of current agricultural systems and, in particular, to the losses of chemical fertilizers and manure in surface and ground-waters, as a consequence of run-off and leaching phenomena. In most cases European recent agrienvironmental schemes envisaged specific measures for the reduction of fertilizer rates and the control of manure applications, in order to limit the releases of nutrients in surface and ground-waters. Substantial financial resources are invested in those measures and therefore the issue raises interest in monitoring and evaluating their effectiveness. Nutrient balance indicators are often used for quantitative assessment of the effectiveness of the measures in limiting the environmental impact of farming activities. N-surplus is one of the most commonly used indicators. The paper refers the results of a research project aimed at assessing the outcomes of agri-environmental measures implemented in the Venice Lagoon Watershed with an approach based upon the gross nitrogen balance, called “Nboxes”. The results of applying the Nboxes procedure to a sample of 550 farms set are presented, evidencing the expectations of greater effectiveness in terms of nitrogen surplus reduction from the measure C.5.1.3a and C.5.1.3b (low input farming and buffer strips. Measures supporting improved irrigation systems, controlled drainage and more rational livestock nutritional programmes and technologies, showed instead only limited potential for tangible contributions to the reduction of nitrogen surplus in cultivated soils.

    Agri-Environment Schemes (AES) to maintain or promote environmentally-friendly farming practices were implemented on about 25% of all agricultural land in the EU by 2002. This article analyses and discusses the actual and potential use of impact models in supporting the design, implementation and evaluation of AES. Impact models identify and establish the causal relationships between policy objectives and policy outcomes. We review and discuss the role of impact models at different stages in the AES policy process, and present results from a survey of impact models underlying 60 agri-environmental schemes in seven EU member states. We distinguished among three categories of impact models (quantitative, qualitative or common sense), depending on the degree of evidence in the formal scheme description, additional documents, or key person interviews. The categories of impact models used mainly depended on whether scheme objectives were related to natural resources, biodiversity or landscape. A higher proportion of schemes dealing with natural resources (primarily water) were based on quantitative impact models, compared to those concerned with biodiversity or landscape. Schemes explicitly targeted either on particular parts of individual farms or specific areas tended to be based more on quantitative impact models compared to whole-farm schemes and broad, horizontal schemes. We conclude that increased and better use of impact models has significant potential to improve efficiency and effectiveness of AES.

    Using bio-transferred feedstuff was a cost-effective approach to improve egg quality and production; particularly, the nutritive diet came from agri-food wastes. In this study, optimization of fermentation conditions and co-cultivation of Neurospora crassa with Lactobacillus plantarum was performed in a simple bioreactor. The optimized fermentation of beer lees substrates through N. crassa led to the hydrolysis rates of crude fiber increasing to 43.27%. Compared to that of using N. crassa alone, the combination of N. crassa and L. plantarum enhanced the content of amino acids (13,120 to 18,032 mg/100 g) on oil-tea seed cake substrates particularly. When hens were fed 10% fermented oil-tea seedcake substrate, the ratio of feed to egg decreased from 3.1 to 2.6, egg production ratio increased from 65.71 to 80.10%, and color of vitelline (Roche) increased from 8.20 to 10.20. Fifteen kinds of carotenoids were identified by HPLC in fermented oil-tea seed cake substrates. The results of this study highlighted that the mixed-fermentation by N. crassa and L. plantarum may be an effective way to convert agri-food wastes into high-valued biomass products, which could have a positive effect on hens and their eggs.

    With consumer concerns increasing over food quality and safety, the food industry has begun to pay much more attention to the development of rapid and reliable food-evaluation systems over the years. As a result, there is a great need for manufacturers and retailers to operate effective real-time assessments for food quality and safety during food production and processing. Computer vision, comprising a nondestructive assessment approach, has the aptitude to estimate the characteristics of food products with its advantages of fast speed, ease of use, and minimal sample preparation. Specifically, computer vision systems are feasible for classifying food products into specific grades, detecting defects, and estimating properties such as color, shape, size, surface defects, and contamination. Therefore, in order to track the latest research developments of this technology in the agri-food industry, this review aims to present the fundamentals and instrumentation of computer vision systems with details of applications in quality assessment of agri-food products from 2007 to 2013 and also discuss its future trends in combination with spectroscopy.

    An experiment upon an agri-silvicultural system involving Willow (Salix alba) tree,Kale (Brassica oleracea var.acephala) and Knol khol (Brassica oleracea var.caularapa) was laid in randomized block designed at farmers' willow field at Shalimar near Sher-e-Kashmir University of Agricultural Sciences and Technology of Kashmir,Srinagar India during 2005 and 2006.The main plot was divided into sub-spots with 8 m ( 2 m in size each in which four two-year-old willow (Salix alba) trees were at a spacing of 2 m ( 2 m in a sub-spot.The intercrops were maintained at recommended spacing and supplied with recommended doses of fertilizers.The benefit-cost ratio in willow plantation intercropped with vegetable crops of Kale and Knol Khol was analyzed and compared with the benefit-cost ratio of sole willow tree forestry.The results showed that every rupee invested in plantation of agri-silvicultural system generates benefit-cost ratio of 2.78 and 2.79 in case of Willow intercropping with Kale and Willow with Knol khol,respectively,while as for sole crop of willows benefit-cost ratio was calculated to be 2.66.These results provided circumstantial evidence in favour of adopting agroforestry involving willow instead of Sole tree forestry.

  8. Etude Climat no. 39 'More than 800 agricultural and agri-food sites affected by the EU ETS'

    International Nuclear Information System (INIS)

    Among the publications of CDC Climat Research, 'Climate Reports' offer in-depth analyses on a given subject. This issue addresses the following points: Agriculture accounts for 9% of Europe's anthropogenic emissions, counting only emissions of methane and nitrous oxide from cattle, crops and pasture. These emissions have two characteristics making their inclusion in the European Emission Trading Scheme (EU ETS) difficult: they are diffuse and depend on a range of fairly complex pedo-climatic factors. Taking into consideration the whole of the agricultural sector, including upstream activities such as production of fertilizer, phyto-sanitary products, animal feed etc., as well as downstream emissions, dominated by the agri-food sector, and also emissions linked to energy consumption by farming installations, the sector's emissions contribution increases considerably. Within this expanded scope, some emissions sources are included in the EU ETS - mainly agri-food industries, but also producers of fertilizer, heated greenhouses and knackers' yards. Even if the proportion of the agricultural and agri-food sector's emissions covered by the emissions trading scheme is minimal, with just 1.5% of all emissions falling within the scope of the EU ETS, more than 800 industrial sites are covered, accounting for 8% of installations covered by the system. The agricultural and agri-food sector are among the net beneficiaries of the EU ETS in the first two phases (2005-2012), with a surplus of 33 million allowances over the period 2008-2011. This surplus, combined with gains from trading in allowances and credits, represents an estimated asset of 495 million euros. Although it has not been fully exploited on the market, this asset largely exceeds the cost of transactions associated with emissions monitoring, reporting and verification (MRV) procedures and compliance work, which is estimated at 30 million euros over the same period. The emission trading scheme has therefore been

  15. The role of agri-environment schemes in conservation and environmental management

    Over half of the European landscape is under agricultural management and has been for millennia. Many species and ecosystems of conservation concern in Europe depend on agricultural management and are showing ongoing declines. Agri-environment schemes (AES) are designed partly to address this. They are a major source of nature conservation funding within the European Union (EU) and the highest conservation expenditure in Europe. We reviewed the structure of current AES across Europe. Since a 2003 review questioned the overall effectiveness of AES for biodiversity, there has been a plethora of case studies and meta-analyses examining their effectiveness. Most syntheses demonstrate general increases in farmland biodiversity in response to AES, with the size of the effect depending on the structure and management of the surrounding landscape. This is important in the light of successive EU enlargement and ongoing reforms of AES. We examined the change in effect size over time by merging the data sets of 3 recent meta-analyses and found that schemes implemented after revision of the EU's agri-environmental programs in 2007 were not more effective than schemes implemented before revision. Furthermore, schemes aimed at areas out of production (such as field margins and hedgerows) are more effective at enhancing species richness than those aimed at productive areas (such as arable crops or grasslands). Outstanding research questions include whether AES enhance ecosystem services, whether they are more effective in agriculturally marginal areas than in intensively farmed areas, whether they are more or less cost-effective for farmland biodiversity than protected areas, and how much their effectiveness is influenced by farmer training and advice? The general lesson from the European experience is that AES can be effective for conserving wildlife on farmland, but they are expensive and need to be carefully designed and targeted.

    2005-06-01

    Full Text Available The Val d Agri area is well-known for oil exploration. An old 500 m deep exploration well in the northern part of this area has been used for long-term hydrogeochemical investigations. The well is characterized by a discharge of about 500 L/min of thermal water (27.8°C and a simultaneous methane gas emission of about 200 L/min. Gas analyses gave evidence that the methane come from a multiple deep reservoir. Continuous records of gas emission showed some anomalous variations occurred during the past three years. The gas flux anomalies were in a distinctive coincidence with self-potential anomalies of one station close to the hydrogeochemical station. The present paper describes the interpretation of these anomalies in relation to the geodynamic activity in the area.

    2014-08-01

    On 2 June 2006 the wastewater produced during the oil and gas field exploitation in High Agri Valley (southern Italy) started to be managed by disposal through pumping the fluids back into the subsurface at the Costa Molina 2 (CM2) injection well, located in the southeastern sector of the valley. The onset of microearthquakes (Ml ≤ 2) after 4 days at about 1.3 km SW of CM2 well suggests fluid injection induced seismicity by the diffusion of pore pressure. Moreover, the space-time evolution of 196 high-resolution relocated events reveals a previously unmapped NE dipping fault. We investigate the physical processes related to the fluid injection induced seismicity and delineate the previously unmapped fault by jointly analyzing seismicity data, geological observations, fluid injection data, the stratigraphic log of the CM2 well, and the electrical resistivity tomography survey carried out in the study area.

    Full Text Available The identification of an appropriate justification for Agri-Environment-Climate (AEC payments is a crucial issue in the new Rural Development Programme (RDP. Given the environmental importance of grasslands in Trentino (Italy, the Management Authority in charge of the RDP decided to integrate an approach based on Ecosystem Services (ES into the calculation of AEC payments. The paper presents the methodology used for this approach as well as the preliminary results. The first step entails building a probabilistic model for the ES, named Sustainable Fodder Production. Model outputs are then integrated with the accounting results based on the Farm Accountancy Data Network (FADN database (2009–2012 with the aim of calculating the additional costs and income waived due to the environmental commitments deriving from the sustainable management of permanent grassland in livestock farming. Sustainability measures imply more extensive management practices that maintain meadows in a healthy state.

    2009-03-01

    The Vercelli rice district in northern Italy plays a key role in the agri-food industry in a country which accounts for more than 50% of the EU rice production and exports roughly 70%. However, although wealth and jobs are created, the sector is said to be responsible for environmental impacts that are increasingly being perceived as topical. As a complex and comprehensive environmental evaluation is necessary to understand and manage the environmental impact of the agri-food chain, the Life Cycle Assessment (LCA) methodology has been applied to the rice production system: from the paddy field to the supermarket. The LCA has pointed out the magnitude of impact per kg of delivered white milled rice: a CO2eq emission of 2.9 kg, a primary energy consumption of 17.8 MJ and the use of 4.9 m3 of water for irrigation purposes. Improvement scenarios have been analysed considering alternative rice farming and food processing methods, such as organic and upland farming, as well as parboiling. The research has shown that organic and upland farming have the potential to decrease the impact per unit of cultivated area. However, due to the lower grain yields, the environmental benefits per kg of the final products are greatly reduced in the case of upland rice production and almost cancelled for organic rice. LCA has proved to be an effective tool for understanding the eco-profile of Italian rice and should be used for transparent and credible communication between suppliers and their customers.

    Full Text Available The Val d'Agri area (southern Italy hosts the biggest on-shore European reservoir and the largest oil/gas pre-treatment plant, named Centro Olio Val d'Agri (COVA, located in a rural/anthropized context. Several hazards are associated to this plant. These are mainly represented by possible impacts of the COVA atmospheric emissions on the local air quality and human health. This work uses a novel approach based on the integration of air quality measurements from the regional monitoring network, additional experimental measurements (i.e., sub-micrometric particulate matter – PM1 and Black Carbon – BC and advanced statistical analyses to provide a preliminary evaluation of the Val d'Agri air quality state and give some indications of specific areas potentially affected by COVA hazards. Results show that the COVA plant emissions exert an impact especially on the air quality of the area closest to it. In this area several pollutants specifically related to the COVA combustion processes (i.e., nitrogen oxides, benzene and toluene show the highest concentration values and significant correlations. The proposed approach represents a first step in the assessment of the risks associated to oil/gas exploration and pre-treatment activities and a starting point for the development of effective and exportable air quality monitoring strategies.

    A PM1 (i.e. particulate matter with an aerodynamic diameter less than 1.0 μm) short-term monitoring campaign was carried out in the Agri Valley (southern Italy) in September 2012. This area is of international concern, since it houses one of the largest European on-shore reservoirs and the largest oil/gas pre-treatment plant (i.e. the Centro Olio Val d'Agri - COVA) within an anthropised context. PM1 measurements were performed in Viggiano, the nearest town to the COVA plant and one of the most populated towns of the Agri Valley. During the study period, the PM1 daily concentrations ranged from 1.2 to 8.4 μg m-3, with a mean value of 4.6 μg m-3. Regarding the PM1 chemical composition, it can be observed that S and typical crustal elements were the most abundant constituents of the PM1 collected. By applying principal component analysis (PCA), it was pointed out that crustal soil, biomass and wood burning, secondary atmospheric reactions involving COVA plant emissions and local soil particles, and traffic were the main sources contributing to the PM1 measured in the area under study. Moreover, a possible contribution of the long-range transport of African dust was observed.

    Full Text Available Val d'Agri is a «recent SSW - NNE graben» located in the middle of the Southern Apennines thrust belt «chain» and emplaced in Plio-Pleistocene.The recent sedimentation of the valley represents a local critical geophysical problem. Several strong near surface velocity anomalies and scattering degrades seismic data in different ways and compromises the seismic visibility. In 1998, ENI and Enterprise, with the contribution of the European Community (ESIT R & D project - Enhance Seismic In Thrust Belt; EU Thermie fund acquired two «experimental seismic and Resistivity lines» across the valley. The purpose of the project was to look for methods able to enhance seismic data quality and optimize the data processing flow for «thrust belt» areas. During the work, it was clear that some part of the seismic data processing flow could be used for the detailed geological interpretation of the near subsurface too. In fact, the integrated interpretation of the near surface tomography velocity/depth seismic section, built for enhancing the resolution of static corrections, with the HR resistivity profile, acquired for enhancing the seismic source coupling, allowed a quite detailed lithological interpretation of the main shallow velocity changes and the 2D reconstruction of the structural setting of the valley.

    The present study focuses on the transformations of a typical Mediterranean agroforestry landscape of southern Italy (high Agri Valley - Basilicata region) that occurred over 24 years. In this period, the valuable agricultural and natural areas that compose such a landscape were subjected to intensive industry-related activities linked to the exploitation of the largest European onshore oil reservoir. Landsat imagery acquired in 1985 and 2009 were used to detect changes in forest areas and major land use trajectories. Landscape metrics indicators were adopted to characterize landscape structure and evolution of both the complex ecomosaic (14 land cover classes) and the forest/non-forest arrangement. Our results indicate a net increase of 11% of forest areas between 1985 and 2009. The major changes concern increase of all forest covers at the expense of pastures and grasses, enlargement of riparian vegetation, and expansion of artificial areas. The observed expansion of forests was accompanied by a decrease of the fragmentation levels likely due to the reduction of small glades that break forest homogeneity and to the recolonization of herbaceous areas. Overall, we observe an evolution towards a more stable configuration depicting a satisfactory picture of vegetation health.

    This study examines the temporal variation of the seismicity in the Val d'Agri (southern Italy) and adjacent areas, for the current seismic hazard evaluation. The temporal variation of the seismicity is expressed as time series of the number of earthquakes, b value of Gutenberg-Richter relationship or b value of the frequency-magnitude distribution and the seismic energy released in the form of logE2/3. The analysis was performed by means of a new research tool that includes visualizing techniques, which helps the interactive exploration and the interpretation of temporal variation changes. The obtained time series show a precursory seismicity pattern, characterized by low and high probability periods, which preceded earthquakes of magnitude M ≥ 4.0. The 75% of the examined cases were successfully correlated with a change in seismicity pattern. The average duration of the low and the high probability periods is 10.6 and 13.8 months respectively. These results indicate that the seismicity temporal variation monitoring in a given area and the recognition of the low and high probability periods can contribute to the evaluation, in regular monthly intervals, of current seismic hazard status.

    In the frame of a national project funded by Eni S.p.A. and developed by three institutes of the National Research Council (the Institute of Methodologies for Environmental Analysis, the Institute of Research for Hydrogeological Protection and the Institute for Electromagnetic Sensing of the Environment), a multidisciplinary approach based on the integration of satellite, aero-photogrammetric and in situ geophysical techniques was applied to investigate an area located in the Montemurro territory in the south-eastern sector of the High Agri Valley (Basilicata Region, southern Italy). This paper reports the results of the in situ geophysical investigation. Electrical Resistivity Tomography (ERT) and Horizontal to Vertical Spectral Ratio (HVSR) by earthquakes and ambient noise measurements were carried out in the study area. The results were supported by interpretation of aerial photos, geological field surveys, morphotectonic investigation and borehole data. The joint analysis of geological, ERT and HVSR data allowed us to (1) show the shallow geological and structural setting, (2) detect the geometry of the different lithological units and their mechanical and dynamical properties, (3) image a previously unmapped fault beneath suspected scarps/warps and (4) characterize the geometry of an active landslide that caused damages to structures and infrastructures.

    The Val d'Agri basin in the Apennines seismic belt hosts the largest oil field in onshore Europe. High-quality recordings from a temporary dense network unravel a swarm of 111 small-magnitude events (ML ≤ 1.8) occurred in June 2006 during the first stage of wastewater injection into a high-rate well. High-precision relative locations define a preexisting blind fault located 1 km below the well inside fractured and saturated carbonates where wastewater is reinjected. Seismicity begins 3 h after the initiation of injection. The seismicity rate strictly correlates with injection curves and temporal variations of elastic and anisotropic parameters. Seismicity is induced by rapid communication of pore pressure perturbations along a high-permeability fault zone favorably oriented with respect to the local extensional stress field. Our accurate 3-D locations of 219 events (ML ≤ 2.2) detected by the local operator network after June 2006 concentrate on the preexisting fault measuring 5 km along dip. Over the following 7.5 years, the seismicity rate correlates with short-term increases in injection pressure.

    Full Text Available The present study focuses on the transformations of a typical Mediterranean agroforestry landscape of southern Italy (High Agri Valley – Basilicata region occurred during 24 years. In this period, the valuable agricultural and natural areas that compose such a landscape were subjected to intensive industry-related activities linked to the exploitation of the largest European on-shore oil reservoir. Landsat imagery acquired in 1985 and 2009 were used to detect changes in forest areas and major land use trajectories. Landscape metrics indicators were adopted to characterize landscape structure and evolution of both the complex ecomosaic (14 land cover classes and the Forest/Non Forest arrangement. Our results indicate a net increase of 11% of forest areas between 1985 and 2009. The major changes concern: increase of all forest covers at the expense of pastures and grasses, enlargement of riparian vegetation, expansion of artificial areas. The observed expansion of forests was accompanied by a decrease of the fragmentation levels likely due to the reduction of small glades that break forest homogeneity and to the recolonization of herbaceous areas. Overall, we observe an evolution towards a more stable configuration depicting a satisfactory picture of vegetation health.

    The economic evaluation of drought impacts is essential in order to define efficient and sustainable management and mitigation strategies. The aim of this study is to evaluate the economic impacts of a drought event on the agricultural sector and measure how they are transmitted from primary production to industrial output and related employment. We fit econometric models to determine the magnitude of the economic loss attributable to water storage. The direct impacts of drought on agricultural productivity are measured through a direct attribution model. Indirect impacts on agricultural employment and the agri-food industry are evaluated through a nested indirect attribution model. The transmission of water scarcity effects from agricultural production to macroeconomic variables is measured through chained elasticities. The models allow for differentiating the impacts deriving from water scarcity from other sources of economic losses. Results show that the importance of drought impacts are less relevant at the macroeconomic level, but are more significant for those activities directly dependent on water abstractions and precipitation. From a management perspective, implications of these findings are important to develop effective mitigation strategies to reduce drought risk exposure.

  1. A new magnetotelluric monitoring network operating in Agri Valley (Southern Italy: study of stability of apparent resistivity estimates

    Full Text Available Variations detected in geophysical, especially electromagnetic, parameters in seismic active areas have been sometimes attributed to modifications of the stress field. Among the different geophysical methods, magnetotellurics (MT could be one of the most effective because it allows us to explore down to seismogenic depths. Continuous MT recording could allow us to evaluate whether possible variations are significantly correlated with the seismic activity of investigated area. To assess the significance of such observations we must be able to say how well an apparent resistivity curve should be reproduced when measurements are repeated at a later time. To do this properly it is essential to know that the estimated error bars accurately represent the true uncertainties in comparing the transfer functions. In this work we will show the preliminary results obtained from the analysis of the data coming from the new MT monitoring network installed in Agri Valley. This analysis gives us the possibility: i to better study the temporal stability of the signals, ii to better discriminate the noise affecting the measures by remote reference estimation. The performed analysis disclosed a relatively low degree of noise in the investigated area, which is a promising condition for monitoring.

    The Val d'Agri area provides the opportunity to analyse active structures in a seismic region for which a large amount of subsurface data is available. This area, which was struck in 1857 by one of the most destructive earthquakes in Italy (MW = 7.03), represents a unique natural laboratory to gain new insights into geometry, modes and rates of faulting controlling crustal deformation in an actively extending orogen. In this study, a crustal geological section through the southern Apennines is discretized into a finite element model (FEM). We present a 2D elastoplastic FEM that reproduces stress perturbations and strain field around the Val d'Agri active fault system. The influence of fault strand activity on interseismic crustal deformation is tested by a series of computer models, whose predictions are compared with the horizontal velocity components of continuous GPS sites in the region and with stress directions and geological data. The best fit with available geological and geophysical constraints is obtained with a 300 km long, 29 km deep model formed by a multilayer including three components having different rheological characteristics and including several shallow, locked fault segments, which branch into a freely slipping major basement fault at depth. Finite element modelling provides new insights into the controversial and widely debated active tectonic setting of the study area, pointing out the fundamental role played by a structural reactivation process involving inherited, long-lived, mature fault systems at depth. Our FEM, reconciling apparently contrasting geological and geophysical constraints from the study area, points to maximum stress build up and strain accumulation at a depth of 15 ± 5 km. Such a depth range is suggested as the most likely one for the nucleation of large events such as the 1857 Val d'Agri earthquake.

    Policy-makers working at the interface of agri-food and public health often deal with complex and cross-cutting issues that have broad health impacts and socio-economic implications. They have a responsibility to ensure that policy-making based on these issues is accountable and informed by the best available scientific evidence. We conducted a qualitative descriptive study of agri-food public health policy-makers and research and policy analysts in Ontario, Canada, to understand their perspectives on how the policy-making process is currently informed by scientific evidence and how to facilitate this process. Five focus groups of 3-7 participants and five-one-to-one interviews were held in 2012 with participants from federal and provincial government departments and industry organizations in the agri-food public health sector. We conducted a thematic analysis of the focus group and interview transcripts to identify overarching themes. Participants indicated that the following six key principles are necessary to enable and demonstrate evidence-informed policy-making (EIPM) in this sector: (i) establish and clarify the policy objectives and context; (ii) support policy-making with credible scientific evidence from different sources; (iii) integrate scientific evidence with other diverse policy inputs (e.g. economics, local applicability and stakeholder interests); (iv) ensure that scientific evidence is communicated by research and policy stakeholders in relevant and user-friendly formats; (V) create and foster interdisciplinary relationships and networks across research and policy communities; and (VI) enhance organizational capacity and individual skills for EIPM. Ongoing and planned efforts in these areas, a supportive culture, and additional education and training in both research and policy realms are important to facilitate evidence-informed policy-making in this sector. Future research should explore these findings further in other countries and contexts.

    In-season monitoring of crop conditions provides critical information for agricultural policy and decision making and most importantly for food security planning and management. Nationwide agricultural monitoring in countries dominated by smallholder farming systems, generally relies on extensive networks of field data collectors. In Tanzania, extension agents make up this network and report on conditions across the country, approaching a "near-census". Data is collected on paper which is resource and time intensive, as well as prone to errors. Data quality is ambiguous and there is a general lack of clear and functional feedback loops between farmers, extension agents, analysts and decision makers. Moreover, the data are not spatially explicit, limiting the usefulness for analysis and quality of policy outcomes. Despite significant advances in remote sensing and information communication technologies (ICT) for monitoring agriculture, the full potential of these new tools is yet to be realized in Tanzania. Their use is constrained by the lack of resources, skills and infrastructure to access and process these data. The use of ICT technologies for data collection, processing and analysis is equally limited. The AgriSense-STARS project is developing and testing a system for national-scale in-season monitoring of smallholder agriculture using a combination of three main tools, 1) GLAM-East Africa, an automated MODIS satellite image processing system, 2) field data collection using GeoODK and unmanned aerial vehicles (UAVs), and 3) the Tanzania Crop Monitor, a collaborative online portal for data management and reporting. These tools are developed and applied in Tanzania through the National Food Security Division of the Ministry of Agriculture, Food Security and Cooperatives (MAFC) within a statistically representative sampling framework (area frame) that ensures data quality, representability and resource efficiency.

    Targeting agri-environmental measures (AEM) improves their effectiveness in the delivery of public goods, provided the necessary coordination with other incentives. In less favoured areas (LFA) measures focusing on the conservation of extensive farming contribute to sustainable land management in these areas. In this paper we investigate the implementation of a possible AEM supporting the improvement of permanent pastures coordinated with the extensive livestock and single farm payments actually in place. Through applying a spatially-explicit mixed integer optimisation model we simulate future land use scenarios for two less favoured areas in Portugal (Centro and Alentejo) considering two policy scenarios: a 'targeted AEM', and a 'non-targeted AEM'. We then compare the results with a 'basic policy' option (reflecting a situation without AEM). This is done with regard to landscape-scale effects on the reduction of fire hazard and erosion risk, as well as effects on farm income. The results show that an AEM for permanent pastures would be more cost-effective for erosion and fire hazard mitigation if implemented within a spatially targeted framework. However when cost-effectiveness is assessed with other indicators (e.g. net farm income and share of grazing livestock) 'non-targeted AEM' implementation delivers the best outcome in Alentejo. In Centro the implementation of an AEM involves important losses of income compared to the 'basic policy'. 'Targeted AEM' tends to favour farms in very marginal conditions, i.e. targeting is demonstrated to perform best in landscapes where spatial heterogeneity is higher. The results also show the risk of farm abandonment in the two studied less favoured areas: in all three scenarios more than 30% of arable land is deemed to be abandoned. PMID:27444720

    Mudrocks rich in organic matter present an attractive exploration target for unconventional gas and oil. The mid-Carboniferous (Visean - Bashkirian) Bowland Shale is developed in a series of fault-bound basins and is considered the principal accumulation of gas-prone shales in the UK. One risk with exploitation of shales is that the rocks may exhibit ductile behaviour and will not respond in an optimal way to hydraulic stimulation programmes. The brittle behaviour of the rock is strongly influenced by mineralogical composition. Approximately 15 m of core from the lower part of the Bowland Shale, has been used to test the feasibility of using Natural Infra-Red (NIR) Spectrometry to characterise the mineralogy of the shale, and compared to analysis using standard XRD techniques (both whole-rock and <2 micron) to confirm the mineralogical constituents of the rock. Clay mineralogy has been the main focus, as their presence within the shale may affect the 'frackability' of the shale. Clay minerals are also easily detected using NIR spectrometry as they display distinctive absorption features in the Short Wave Infrared region of the electromagnetic spectrum. The benefits of using a handheld NIR spectrometer (AgriSpec) is that it provides a rapid, non-destructive and highly portable method for characterising clay mineralogy. This method may represent a simple solution to the initial characterisation of what are challenging rocks to characterise: thick accumulations (locally in excess of 3500 m) with few marker horizons to enable correlation between basins. Results demonstrate that clay minerals such as dickite, kaolinite and smectite (as well as other characteristic minerals such as siderite; calcite and gypsum) can be identified within the Bowland Shale using this technique.

  9. Is it worth protecting groundwater from diffuse pollution with agri-environmental schemes? A hydro-economic modeling approach.

    In Europe, 30% of groundwater bodies are considered to be at risk of not achieving the Water Framework Directive (WFD) 'good status' objective by 2015, and 45% are in doubt of doing so. Diffuse agricultural pollution is one of the main pressures affecting groundwater bodies. To tackle this problem, the WFD requires Member States to design and implement cost-effective programs of measures to achieve the 'good status' objective by 2027 at the latest. Hitherto, action plans have mainly consisted of promoting the adoption of Agri-Environmental Schemes (AES). This raises a number of questions concerning the effectiveness of such schemes for improving groundwater status, and the economic implications of their implementation. We propose a hydro-economic model that combines a hydrogeological model to simulate groundwater quality evolution with agronomic and economic components to assess the expected costs, effectiveness, and benefits of AES implementation. This hydro-economic model can be used to identify cost-effective AES combinations at groundwater-body scale and to show the benefits to be expected from the resulting improvement in groundwater quality. The model is applied here to a rural area encompassing the Hesbaye aquifer, a large chalk aquifer which supplies about 230,000 inhabitants in the city of Liege (Belgium) and is severely contaminated by agricultural nitrates. We show that the time frame within which improvements in the Hesbaye groundwater quality can be expected may be much longer than that required by the WFD. Current WFD programs based on AES may be inappropriate for achieving the 'good status' objective in the most productive agricultural areas, in particular because these schemes are insufficiently attractive. Achieving 'good status' by 2027 would demand a substantial change in the design of AES, involving costs that may not be offset by benefits in the case of chalk aquifers with long renewal times.

    Full Text Available The main aim of this paper is to introduce a new certified applied methodology for Assessing Suppliers in Agri-Food Complex as a tool for company competitiveness. The work is based on the results obtained in the research project NAZV QG60148/2005 funded by the Czech Ministry of Agriculture and on the requirements of agricultural practice. The novelty lies in the use of practices of the worldwide respected GLOBALG.A.P. standard (formerly EUREPGAP as yet not well known in our country. Based on the practical experience of the authors with the application of food safety standards in the food manufacturing industry and application of GLOBALG. A.P. standard in agricultural primary production, risk and hazard analysis was developed for the product group of fruit and vegetables. Subsequently, a checklist was designed for the implementation of the suppliers’ audit. The result is a methodology for food manufacturers based on the identification of sources of risks in primary production, which can threaten food safety. As part of the introduced methodology are proposed methodological criteria for evaluating suppliers of fruit and vegetables, including rating scales and the possibilities of its implementation. Different variations of the introduction of this approach are discussed from the management, time, and financial viewpoints. The use of this procedure in practice aims to reduce the likelihood of hygiene and health hazards of the basic input raw material according to the principles of the certified standards and thus strengthen the competitiveness of a given manufacturer on the market.

    Today, with the advent of modern processing techniques in the area of value addition to agri resources, food irradiation has made a big dent in terms of extension of shelf life and confidence of making the food free from microbial and other contaminants and need to be really harnessed more than what we are doing. However, there is still certain amount of stigma attached to this technology not because the technology is un-ripe but it is because of lack of awareness with the masses as regards to the safety of the foods that are processed by irradiation

    Full Text Available A methodological framework was designed to assess the effectiveness of agri-environmental policy measures adopted by the Veneto Region to reduce diffuse water pollution of agricultural origin. Two already existing methodologies were combined in a new flexible approach for policy assessment: Conceptual Modelling and Bayesian Networks (BNs. The former supported the development of a shared conceptual model (a cognitive map of the agro-ecosystem of the study area; while the latter allowed the development of a probabilistic model coherent with the cognitive map. BNs were selected because they allow analyses with scarce data; they can be updated when further information becomes available, and are easily understandable by layperson. The paper reports the results obtained in the Venice Lagoon Watershed (VLW case study, where the current agri-environmental measures were assessed in order to identify their effectiveness in terms of reduction of nitrogen releases in water bodies connected to the lagoon ecosystem. Preliminary results obtained by implementing expert opinions in the BN pointed out the likely limited effects of the measures on the declared objective of

    Full Text Available The atmospheric concentrations of 17 trace elements (Al, Ca, Cd, Cr, Cu, Fe, K, Li, Mg, Mn, Na, Ni, P, Pb, S, Ti and Zn were measured by means of the "lichen-bag" technique in the Agri Valley (southern Italy. The lichen samples were collected from an unpolluted site located in Rifreddo forest (southern Italy. The bags were exposed to ambient air for 6 and 12 months. The exposed-to-control (EC ratio values highlighted that the used lichen species were suitable for biomonitoring investigations. The results showed that the concentrations of almost all the examined trace elements increased with respect to the control after 6–12 month exposures. Furthermore, Ca, Al, Fe, K, Mg and S were the most abundant trace elements both in the 6 and 12 month-exposed samples. Moreover, principal component analysis (PCA results highlighted that the major sources of the measured atmospheric trace elements were related both to anthropogenic contributions due to traffic, combustion processes, agricultural practices, construction and quarrying activities, and to natural contributions mainly represented by the re-suspension of local soil and road dusts. In addition, the contribution both of secondary atmospheric reactions involving Centro Olio Val d'Agri (COVA plant emissions and the African dust long-range transport were also identified.

    In this work, environmental heavy metal contamination in the Val d'Agri area of Southern Italy was monitored, measuring the accumulation of 18 heavy metals (U, Hg, Pb, Cd, As, Sr, Sn, V, Ni, Cr, Mo, Co, Cu, Zn, Ca, Mn, Fe, and Al) in the organs of animals raised in the surrounding area (kidney, lung, and liver of bovine and ovine species). Val d'Agri features various oil processing centers which are potentially a significant source of environmental pollution, making it essential to perform studies that will outline the state of the art on which any recovery plans and interventions may be developed. The analysis was carried out using official and accredited analytical methods based on inductively coupled plasma mass spectrometry, and the measurements were statistically processed in order to give a contribution to risk assessment. Even though five samples showed Pb and Cd concentrations above the limits defined in the European Commission Regulation (EC) No 1881/2006, the mean concentrations of most elements suggest that contamination in this area is low. Consequently, these results also suggest that there is no particular risk for human exposure to toxic trace elements. Nevertheless, the findings of this work confirm that element accumulation in ovine species is correlated with geographical livestock area. Therefore, ovine-specific organs might be used as bioindicators for monitoring contamination by specific toxic elements in exposed areas. PMID:27165602

    The EU has implemented agri-environmental programs to minimize the negative environmental impacts of agriculture. This study investigates the correlation between the implementation of these measures and the groundwater nitrate concentration in Baden Wurttemberg. Groundwater quality data from the monitoring network was used in a geo-statistical methodology, using two methods, to generate maps of groundwater nitrate distribution from 1990 to 2012. The covered area of each agri- environmental measure that is considered to have a beneficial impact on groundwater quality was attributed to each county in the state for the period of 2000-2012. Using ArcGIS 10.1 and R statistical software, the correlations between the evolutions of these two phenomenon were determined using Spearman's correlation coefficient and the corresponding p value, using three different methods (that incorporate different degrees of additional information such as the evolution of the TUAA and the spatial positioning and extent of agricultural land). Also the evolution of groundwater nitrate concentration was determined for different land use types for the period of 1990-2012. Variations were visible between the different used methods, however, all of them showed very similar patterns: there were significantly more negative correlations than positive; this was also true for the intensity of the correlations (the value of the correlation coefficient), in some instances negative correlation coefficients went above 0.9 (p permanent crops > heterogeneous agricultural areas > pastures >= urban fabric >= industrial, commercial and transport units > forests > artificial non-agricultural areas > scrubs and/or herbaceous vegetation.

    The atmospheric concentrations of 17 trace elements (Al, Ca, Cd, Cr, Cu, Fe, K, Li, Mg, Mn, Na, Ni, P, Pb, S, Ti and Zn) were measured by means of the "lichen-bag" technique in the Agri Valley (southern Italy). The lichen samples were collected from an unpolluted site located in Rifreddo forest (southern Italy), about 30 km away from the study area along the north direction. The bags were exposed to ambient air for 6 and 12 months. The exposed-to-control (EC) ratio values highlighted that the used lichen species were suitable for biomonitoring investigations. The results showed that the concentrations of almost all the examined trace elements increased with respect to the control after 6-12-month exposures. Furthermore, Ca, Al, Fe, K, Mg and S were the most abundant trace elements both in the 6-month and 12-month-exposed samples. Moreover, principal component analysis (PCA) results highlighted that the major sources of the measured atmospheric trace elements were related both to anthropogenic contributions due to traffic, combustion processes agricultural practices, construction and quarrying activities, and to natural contributions mainly represented by the re-suspension of local soil and road dusts. In addition, the contribution both of secondary atmospheric reactions involving Centro Olio Val d'Agri (COVA) plant emissions and the African dust long-range transport were also identified.

  3. Proceedings of the 65. conference of the Ordre des agronomes du Quebec : Effects of climate change on agriculture and agri-food sectors : local solutions

    International Nuclear Information System (INIS)

    This conference provided a forum for the exchange of scientific knowledge concerning new management tools and agricultural practices that will ensure sustainable development in the agriculture and agri-food sectors in Quebec in light of climate change. Agricultural practices were examined in an effort to see how greenhouse gas (GHG) emissions can be reduced. A review of the knowledge accumulated to date on climate change was presented along with a look at the impact of greenhouse gas emissions on Quebec's agricultural sector. Climate and the greenhouse effect were discussed, with particular emphasis on a European perspective of the agricultural sector. Nine presenters also participated in 3 smaller conferences on specific themes which examined GHG sources and methods to reduce emissions in animal and plant production. The impacts of climate change and adaptation methods in Quebec were discussed. Twelve of the 13 papers were indexed separately for inclusion in this database

    Full Text Available  Never before has food been as safe and secure as it is today, but simultaneously, society has become increasingly critical towards agricultural and food related issues. This two-sided development between society and agribusiness will be analyzed using Framing Theory. A quantitative semantic analysis was applied to evaluate the web-based social media in Germany. 50,931 web posts were collected covering 21 issues identified as relevant for the agri-food sector. The results show that all contentious issues are mainly framed in a two-sided way. The modern productivity-driven industry is judged as a negative development, trends returning to a more natural food production are seen as positive.

    Full Text Available The aim of the research was to analyse the functioning of agricultural farms located in the areas of Natura 2000 network. The research was conducted in 2015 among 70 farmers whose lands were located in the Valley of Biebrza River in Podlaskie Voivodeship. The main research method was a questionnaire. According to the results of the research, the agri-environmental scheme is a proper tool that combines the environmental protection and local producers’ interests; however, it requires the implementation of a supplement adjusted to the nature of the areas. It is also indicated that even though the economic part of the program does not raise any doubts, the natural eff ects are practically not recognized, which may lead to an incomplete protection of precious species and habitats.

    Meteorological forcing is essential to hydrological and hydro-geological modeling. In the case of the semi-arid catchment of Merguellil in Tunisia, long term time series are only available in the plain for a SYNOP station. Other meteorological stations have been installed since 2010. Therefore, this study aims at qualifying the reliability of the meteorological forcing necessary for an integrated model conception. We compare the meteorological data from 7 stations (sources: WMO and our own station), inside and around the Merguellil catchment, with daily gridded data at 25*25 km from AGRI4CAST and 50*50km from WFDEI. AGRI4CAST (Biaveti et al, 2008) is an interpolated dataset based on actual weather stations produced by the Joint Research Centre (JRC) for the Monitoring Agricultural Resources Unit (MARS). The WFDEI second version dataset (Weedon et al, 2014) has been generated using the same methodology as the widely used WATCH Forcing Data (WFD) by making use of the ERA-Interim reanalysis data. The studied meteorological variables are Rs, Tmoy, U2, P, RH and ET0, with the scores RMSE, bias and R pearson. Regarding the AGRI4CAST dataset, the scores are established over different periods according to variables based on stepping between the observed and interpolated data. The scores show good correlations between the observed temperatures, but with a spatial variability bound to the stations elevations. The moderate and interpolated radiations also show a good concordance indicating a good reliability. The R pearson score obtained for the values of relative humidity show a good correlation between the observations and the interpolations, however, the short periods of comparisons do not allow obtaining significant information and the RMSE and bias are important. Wind speed has an important negative bias for a majority of stations (positively for only one). Only one station shows concordances between the data. The study of the data indicates that we shall have to adjust

    This study presents the preliminary environmental balance of the Alta Val d'Agri (Basilicata Region, Southern Italy), an area of great naturalistic interest characterized by the presence of huge oil and gas fields. The Driving Forces-Pressure-State-Impact-Responses (DPSIR) methodology was used to outline the background in terms of environmental impacts mainly caused by oil extraction activities, as well as potential existing responses. The study aims at providing stakeholders with an exhaustive framework to identify the existing data, the main sources of pollution, their potential impacts, the associated industrial risks and the existing policy strategies. Moreover, the DPSIR approach allows the identification of the vulnerable areas and the definition of targeted actions for a sustainable development of the area.

    Full Text Available We present the results of a geophysical survey carried out to outline the structural modelling of Quaternary slopedeposits in the northern part of the Agri high valley (Basilicata, Southern Italy. Quaternary folding and brittle deformations of the subaerial slope deposits have been studied combining electrical imaging and self-potential surveys with geological structural analysis. This integrated approach indicates that the area underwent both transpressional and transtensional tectonics during Pleistocene times as testified by the existence of a push up structure in the basement buried by deformed Quaternary breccias. On this basis, the valley appears to be a more complex structure than a simple extensional graben, as traditionally assumed in the literature.

    2015-12-01

    Full Text Available Agri-environmental schemes (AES in irrigated olive groves (IOG in southern Spain were assessed based on farmers’ preferences toward these schemes. A choice experiment was used in this ex-ante assessment, with the inclusion of some innovative elements, such as collective participation and ecological focus areas (EFA. The results showed that farmers’ mean willingness to accept (WTA participation in collective rather than individual AES was €124.5/ha. Their mean WTA for an additional 1% of EFA was €64.6/ha, while regarding the use of other agri-environmental practices, they showed a WTA of €6.3/ha and €114.7/ha for an additional 1% in the use of cover crops (CC in olive grove areas and restrictive management of CC, respectively. These estimates were strongly influenced by farmers’ expectations and socio-economic characteristics, as well as farm management. We obtained that farmers’ expectations of no farm takeover reduce WTA for collective participation, whereas agricultural training and having at least a secondary-school education reduce farmers’ WTA for EFA and restrictive management of the CC, respectively. Conversely, harvesting ground olives increased farmers’ WTA for a high proportion of the area under CC. The analysis of the AES scenarios showed moderately high estimates of total WTA (€101-349/ha, especially when collective participation is required (€225-474/ha. The results supported the argument that there are efficient ways to encourage public goods provision, overcoming trade-offs with private goods provision by identifying the type of joint production.

  10. Potential benefits of commercial willow Short Rotation Coppice (SRC) for farm-scale plant and invertebrate communities in the agri-environment

    The cultivation of bioenergy crops (BECs) represents a significant land-use change in agri-environments, but their deployment has raised important issues globally regarding possible impacts on biodiversity. Few studies however, have systematically examined the effect of commercial scale bioenergy plantations on biodiversity in agri-ecosystems. In this study we investigate how the abundance and diversity of two key components of farmland biodiversity (ground flora and winged invertebrates) varied between mature willow Short Rotation Coppice (SRC) and two alternative land-use options (arable crops and set-aside land). Although the abundance of winged invertebrates was similar across all land-uses, taxonomic composition varied markedly. Hymenoptera and large Hemiptera (>5 mm) were more abundant in willow SRC than in arable or set-aside. Similarly although plant species richness was greater in set-aside, our data show that willow SRC supports a different plant community to the other land-uses, being dominated by competitive perennial species such as Elytrigia repens and Urtica dioica. Our results suggest that under current management practices a mixed farming system incorporating willow SRC can benefit native farm-scale biodiversity. In particular the reduced disturbance in willow SRC allows the persistence of perennial plant species, potentially providing a stable refuge and food sources for invertebrates. In addition, increased Hymenoptera abundance in willow SRC could potentially have concomitant effects on ecosystem processes, as many members of this Order are important pollinators of crop plants or otherwise fulfil an important beneficial role as predators or parasites of crop pests.

    2014-01-01

    Nowadays, agri-products production and distribution systems are becoming more and more interdependent, integrated, and globalized. The two main themes toward agri-products around the modern world include maintaining safety and improving quality. Based on the information communication technologies (ICTs) and the internet of things (IOT) technologies, traceability through the entire agri-products supply chain will effectively address safety, quality, and defense issues of agri-products by providing precise, real-time, transparent, and reliable information from the farm to the table. Traceability systems are capable of minimizing the degree of information asymmetry between producers and consumers by collecting and sharing information among all partners of the supply chain, promoting the agri-products safety responsibility by implement track and trace functions along the supply chain, and helping strengthen confidence of the customers toward agri-products. Since traceability systems are becoming an important tool for monitoring and managing agri-product flows through the supply chains, many developing and developed countries around the world put great focus on them and try to introduce traceability into various kinds of agri-products supply chains. This review described and summarized the latest progress of the agri-products traceability development in the most advanced regions of agriculture produce all over the world, which comprised three main aspects:laws and regulations, standards and norms, and promotion and implementation. The agri-product traceability legal system has been developed in the Europe Union (EU), which puts "No. 178/2002 Act"at its core. It is divided into two levels:the upper level is the basic laws that set general principles, relatively; the lower level is specific articles and requirements for different kinds of agri-products based on the upper level. The EU started the Promoting European Traceability Excellence&Research (PETER) project from

    Full Text Available Abstract Background Agriculture is the dominant land use throughout much of Europe. Changes to farming practices have led to concerns about negative impacts on biodiversity, and current agricultural policy has an emphasis towards conservation. The objective of this study was to investigate and describe the nature and coverage of research pertaining to the effectiveness of integrated farm management, organic farming and agri-environment schemes as interventions for conserving biodiversity in temperate Europe. Systematic mapping methodology was adapted from social sciences, and used to create a searchable database of relevant research. Methods Searches were made of 10 electronic databases containing peer reviewed journals, PhD theses, conference proceedings and organisational reports. Web searches for relevant research were also made. The title and abstracts of results were examined for relevance. Studies were included when published in English, when an intervention was applied to increase biodiversity or species diversity on farmland, and where there was a measured effect on study organism(s. Correlative and manipulative studies from temperate Europe were included. The research was incorporated into a searchable database (systematic map and key wording used to describe, categorise and code studies. Results The searches identified 83,590 records. Following removal of duplicates and the application of inclusion criteria, 743 references were coded for the final systematic map database. Most of the studies reported were from Western Europe, particularly from the UK. Invertebrates were the most commonly studied organism followed by plants and birds, and field margins were the most commonly studied biotope. Conclusions The systematic map describes the scope of research on the topic. It can be used to inform future primary research, or research synthesis and evaluation methods such as systematic review.

    2013-10-01

    Simultaneous measurements of PM10, PM2.5 and PM1 (i.e., aerosol particles with aerodynamic diameter less than 10, 2.5 and 1 μm, respectively) daily mass concentrations and daily particle number concentration were performed for the first time in Agri Valley (Basilicata Region - Southern Italy) from July to November 2011. This area is characterized by anthropogenic activities having high potential environmental and human health impacts. In fact, the Agri Valley houses the largest European on-shore reservoir and the largest crude oil pre-treatment plant within an anthropized area. The PM measurements were analyzed combining an innovative statistical methodology, the Singular Spectral Analysis, with forecast models and remote sensing observations. Our findings show that most of the PM collected was made up of particles in the fine and sub-micrometric fractions (i.e., PM2.5 and PM1, respectively) very likely originated by common anthropogenic sources. Moreover, PM2.5 and PM1 daily mass concentrations were characterized by a slightly increasing trend that could be related to the contribution of local sources, such as the crude oil pre-treatment plant, whose combustion processes also produce the emission of particles mainly in the fine and sub-micrometric size ranges. The integrated use of model forecasts, satellite observations and in-situ measurements shows that the only PM10 exceedance was affected by the contribution of Saharan dust, while the three PM2.5 exceedances were mainly due to local anthropogenic sources. Finally, the analysis of the PM10 and PM2.5 Air Quality Index (AQI) values shows that air quality was always “good” with respect to PM10 and “moderate” with respect to PM2.5 suggesting that fine particles, if they will be not kept under control, should represent a real problem also posing health risks to the population living close to the crude oil pre-treatment plant.

    Several agri-environment measures in Austria are presumed to also mitigate climate change. These are mainly measures that lead to an increase or stabilization of soil organic carbon (SOC) in arable soils, like e.g. organic farming, legumes and cover crops in the crop rotation as well as the application of organic fertilizers. A reduction of mineral fertiliser application may also reduce greenhouse gas emissions. The results of the study aim to evaluate different agricultural practices on their impact on SOC changes. Data from long term field experiments in Austria with different tillage systems and incorporation rates of crop residues and manure are used to determine effects of agricultural practices on SOC changes. Management factors that compare results from different activities on cropland are calculated and compared with international data. Furthermore these data are used to verify results gained from the application of humus balance model (VDLUFA). For the upscaling of potential SOC changes at regional level (federal states of Austria) data of the IACS - Integrated Administrative Control System are applied in the humus balance model. In order to cover the range of possible SOC changes three different approaches of the humus balance model are introduced and the results will be presented.

    2015-01-01

    Full Text Available A PM1 geochemical and mineralogical study using Scanning Electron Microscopy (SEM was performed on a pilot site in the Agri Valley which is close to the oil pre-treatment plant (C.O.V.A of the Europe's largest on-shore hydrocarbon reservoir. The study identified PM1 geochemical and mineralogical characters in a period before, during and immediately after a burning torch flare event. The finer fraction (DFe DFe ≥ 0.7 μm, natural particles originating from crustal erosion and soot were abundant. Fine quartz particles and lower Al/Si ratios are markers for desert dust origin, proving that a Saharan dust episode which occurred during the observation period played a significant role in supplying geogenic aerosol components to the PM1. Largest amounts of ≥0.7 μm fraction particles observed on the day of flare event may be due to a greater supply of Saharan geogenic particles. Soot had been significantly increasing long before the flare event, suggesting that this increase is also related to other causes, although we cannot exclude a contribution from flaring. S-rich aerosol consisted mainly of mixed particles originating from deposition and heterogeneous nucleation of secondary sulfates on mineral dust. Only-S particles were identified in the ≥0.7 μm fraction following the flare event. These particles may be indicators of larger amounts of sulphur in the atmosphere.

    2014-10-01

    Full Text Available The competitiveness of a supply chain is driven by the ability of supply chain governance structures to adapt to the chains’ continuously changing technical and organizational characteristics. The present study addresses the adoption of sustainability improvement options in the area of organization and management in the agri-food sector; within this framework the study proposes a tool for assessing the impact of sustainability oriented processes on the supply chain governance structures, in turn influencing the competitiveness of the supply chain. Two different approaches, proposed by (Gereffi et al., 2005 and (Hobbs and Young, 2000 have been linked to provide a theoretical framework for the tool development. The proposed new conceptual framework links the dimensions defining five different governance structures complexity of transaction, ability to codify and capabilities in the supply-base (Gereffi et al., to the product characteristics, regulatory and technology aspects defined by Hobbs and Young as drivers influencing the vertical coordination of supply chains. The method suggested for measuring the relations between improvement options and the chain governance structure is the adoption of experts’ evaluations. This method improves the tool capacity to provide a context-related supply chain governance structure assessment and management.

  1. A Decision Support System Coupling Fuzzy Logic and Probabilistic Graphical Approaches for the Agri-Food Industry: Prediction of Grape Berry Maturity.

    Directory of Open Access Journals (Sweden)

    Nathalie Perrot

    Full Text Available Agri-food is one of the most important sectors of the industry and a major contributor to the global warming potential in Europe. Sustainability issues pose a huge challenge for this sector. In this context, a big issue is to be able to predict the multiscale dynamics of those systems using computing science. A robust predictive mathematical tool is implemented for this sector and applied to the wine industry being easily able to be generalized to other applications. Grape berry maturation relies on complex and coupled physicochemical and biochemical reactions which are climate dependent. Moreover one experiment represents one year and the climate variability could not be covered exclusively by the experiments. Consequently, harvest mostly relies on expert predictions. A big challenge for the wine industry is nevertheless to be able to anticipate the reactions for sustainability purposes. We propose to implement a decision support system so called FGRAPEDBN able to (1 capitalize the heterogeneous fragmented knowledge available including data and expertise and (2 predict the sugar (resp. the acidity concentrations with a relevant RMSE of 7 g/l (resp. 0.44 g/l and 0.11 g/kg. FGRAPEDBN is based on a coupling between a probabilistic graphical approach and a fuzzy expert system.

However distributional data from some Southern Italy areas are scanty, in particularly for the Basilicata region. In this study, we present the results of field and bibliographic survey on the amphibians of the “Appennino Lucano, Val d’Agri e Lagonegrese” National Park (almost 70,000 ha. We recorded breeding activity of 12 amphibian species in 307 sites, for a total of 493 records. For some endemic species we provide new ecological data, such as new altitudinal limit (Salamandrina terdigitata or expansion of the annual activity cycle (Bombina pachypus. Indices of diffusion, density and rarity were applied to test the status of each species in the Park. Correspondence analyses showed a clear aquatic habitat partitioning between anurans and urodelans and, concerning the latter, between newts and salamanders, newts being strictly dependent on artificial water bodies. Our results support the growing idea, recently formalized by the IUCN, that maintaining and restoring artificial water bodies may be fundamental for an appropriate conservation management of amphibian communities in Mediterranean rural landscapes.

    Full Text Available This study established an immunoaffinity column for selective extraction of aflatoxins in agri-products. Specifically, the immunoaffinity column was developed by covalently coupling monoclonal antibody 1C11 against aflatoxins to amino-silica gel microparticles and then packing these into a cartridge. The extraction conditions were thoroughly optimized in terms of loading, washing and eluting solutions. Under the optimal conditions, the immunoaffinity column had a capacity of 200 ng of aflatoxins. The detection limits (S/N = 3 for aflatoxin G1, B1, G2 and B2 were 0.03, 0.07, 0.05 and 0.09 μg·kg−1, and the corresponding quantification limits (S/N = 10 were 0.10, 0.25, 0.18 and 0.30 μg·kg−1, respectively. The recoveries of aflatoxins in samples were 90.1%–104.4% and RSDs were <4.4%. The developed method was further applied to the determination of aflatoxins in peanut, vegetable oil and tea samples, and the results indicated that peanut (26.9%, vegetable oils (28.0% and tea (5.3% samples were contaminated with aflatoxins, with levels ranging from 0.49 to 20.79 μg·kg−1.

    polarization is investigated using 200 seismograms recorded by a network of 20 stations installed on rock outcrops in the Val d'Agri region that hosts the largest oil fields in the southern Apennines (Italy). Polarization is assessed both in the frequency and time domains through the individual-station horizontal-to-vertical spectral ratio and covariance-matrix analysis, respectively. We find that most of the stations show a persistent horizontal polarization of waveforms, with a NE-SW predominant trend. This direction is orthogonal to the general trend of Quaternary normal faults in the region and to the maximum horizontal stress related to the present extensional regime. According to previous studies in other areas, such a directional effect is interpreted as due to the presence of fault-related fracture fields, polarization being orthogonal to their predominant direction. A comparison with S wave anisotropy inferred from shear wave splitting indicates an orthogonal relation between horizontal polarization and fast S wave direction. This suggests that wavefield polarization and fast velocity direction are effects of the same cause: The existence of an anisotropic medium represented by fractured rocks where shear wave velocity is larger in the crack-parallel component and compliance is larger perpendicularly to the crack strike. The latter is responsible for the observed anisotropic pattern of amplitudes of horizontal ground motion in the study area.

    This presentation reported on an experimental study in which biohydrogen was produced via anaerobic fermentation of dairy wastewater using a 6 L sequencing batch reactor. Tests were performed at ambient temperature and varying pH, hydraulic retention time (HRT) and organic loading rate (OLR). The seed sludge was not pretreated. The tests showed that methanogenic activity could be suppressed via short HRT and large OLR changes. However, the maximum hydrogen production rate was only 0.08 L/L per day without pH control. The rate of hydrogen production increased considerably when sucrose-rich synthetic wastewater was used as the substrate, and when pH was controlled. When HRT was reduced from 2.5 days to 1.25 days, observed hydrogen yield and hydrogen production rate reached 73 per cent and 4.38 L/L per day, respectively, for an optimal pH of 4.0. Volatile fatty acid was analyzed in order to determine the microbial metabolic pathway that favours increased hydrogen production. It was concluded that the co-fermentation of agri-food wastewater could improve the utilization of animal wastewater for the production of biohydrogen.

  7. When does State Interference with Property (now Amount to Expropriation? An Analysis of the Agri SA Court's State Acquisition Requirement (Part II

    Full Text Available Section 25 of the Constitution provides two ways in which the state may interfere with property rights, namely deprivation (section 25(1 and expropriation (section 25(2. As only the latter requires compensation, there is an incentive for property holders to label any infringement with their property as expropriation in the hope of being compensated for their losses. It is therefore essential to have a principled distinction between deprivation and expropriation, especially given the danger that uncertainty in this regard can hold for legitimate land reform initiatives, which often entail severe limitations on property. This contribution attends to Agri South Africa v Minister for Minerals and Energy 2013 4 SA 1 (CC, where the Constitutional Court recently revisited this distinction and held that the distinguishing feature of expropriation is that it entails state acquisition of property. Without state acquisition the interference can (at most amount to deprivation. Unfortunately, viewing state acquisition as the "key requirement" for expropriation is problematic. Firstly, it ignores the true nature of this feature in that it is only a consequence of a valid expropriation rather than a pre-requisite for it – at least in terms of pre-constitutional law. It is therefore inaccurate, concerning both pre- and post-constitutional expropriation case law, to regard acquisition as an indispensable requirement for expropriation. Secondly, limiting the constitutional property inquiry to whether or not the state acquired property appears inadequate as a means of solving difficult cases where the state acquires property pursuant to infringements like taxation and criminal forfeiture. As both these examples result in state acquisition, there must be another explanation of why they do not amount to expropriation.

    Gas flaring is one of the most controversial energetic and environmental issues the Earth is facing, moreover contributing to the global warming and climate change. According to the World Bank, each year about 150 Billion Cubic Meter of gas are being flared globally, that is equivalent to the annual gas use of Italy and France combined. Besides, about 400 million tons of CO2 (representing about 1.2% of global CO2 emissions) are added annually into the atmosphere. Efforts to evaluate the impact of flaring on the surrounding environment are hampered by lack of official information on flare locations and volumes. Suitable satellite based techniques could offers a potential solution to this problem through the detection and subsequent mapping of flare locations as well as gas emissions estimation. In this paper a new methodological approach, based on the Robust Satellite Techniques (RST), a multi-temporal scheme of satellite data analysis, was developed to analyze and characterize the flaring activity of the largest Italian gas and oil pre-treatment plant (ENI-COVA) located in Val d'Agri (Basilicata) For this site, located in an anthropized area characterized by a large environmental complexity, flaring emissions are mainly related to emergency conditions (i.e. waste flaring), being the industrial process regulated by strict regional laws. With reference to the peculiar characteristics of COVA flaring, the RST approach was implemented on 13 years of EOS-MODIS (Earth Observing System - Moderate Resolution Imaging Spectroradiometer) infrared data to detect COVA-related thermal anomalies and to develop a regression model for gas flared volume estimation. The methodological approach, the whole processing chain and the preliminarily achieved results will be shown and discussed in this paper. In addition, the possible implementation of the proposed approach on the data acquired by the SUOMI NPP - VIIRS (National Polar-orbiting Partnership - Visible Infrared Imaging

    Different kinds of atmospheric pollution affect human health and the environment at local and global scale. The petroleum industry represents one of the most important environmental pollution sources, accounting for about 18% of well-to-wheels greenhouse gas (GHG) emissions. The main pollution source is represented by the flaring of gas, one of the most challenging energy and environmental problems facing the world today. The World Bank has estimated that 150 billion cubic meters of natural gas are being flared annually, that is equivalent to 30% of the European Union's gas consumption. Since 2002, satellite-based methodologies have shown their capability in providing independent and reliable estimation of gas flaring emissions, at both national and global scale. In this paper, for the first time, the potential of satellite data in estimating gas flaring volumes emitted from a single on-shore crude oil pre-treatment plant, i.e. the Ente Nazionale Idrocarburi (ENI) Val d'Agri Oil Center (COVA), located in the Basilicata Region (South of Italy), was assessed. Specifically, thirteen years of night-time Moderate Resolution Imaging Spectroradiometer (MODIS) data acquired in the medium and thermal infrared (MIR and TIR, respectively) bands were processed. The Robust Satellite Techniques (RST) approach was implemented for identifying anomalous values of the signals under investigation (i.e. the MIR-TIR difference one), associated to the COVA flares emergency discharges. Then, the Fire Radiative Power (FRP), computed for the thermal anomalies previously identified, was correlated to the emitted gas flaring volumes, available for the COVA in the period 2003 - 2009, defining a satellite based regression model for estimating COVA gas flaring emitted volumes. The used strategy and the preliminary results of this analysis will be described in detail in this work.

    This study mainly focused on lutein content in several selected crops grown in southern Ontario, Canada. Marigold flower, a good rotation crop for the control of nematodes in tobacco fields was found to contain 0.77% lutein (after saponification, on dry basis). A high-speed counter-current chromatography (HSCCC) method using a two-phase solvent system consisting of hexane-ethanol-water (6:4.5:1.5, v/v/v) was developed for the purification of lutein from the saponification mixture of marigold flower extract. The purity of lutein prepared using this HSCCC method was 97%. Free lutein was found to be the predominant form in three squash varieties, and it was mostly found in the peel rather than the commonly consumed flesh. Sweet Mamma, Buttercup and Pepper squash varieties contained 25.4, 18.4 and 30.1mg/100g fresh weigh (FW) of lutein in the peels, respectively. These concentrations were significantly higher than that in spinach and kale (3.7 and 12.3 mg/100 g FW). beta-Carotene was found most in the peel of Sweet Mamma squash at 13.6 mg/100g FW, whereas it was below 2mg/100g FW in all other samples. Cooking increased extractable free lutein by 22-65% in squash peels. Lutein in Yukon Gold potato was at ca. 0.4 mg/100 g FW. Certain Yukon Gold was also found to contain violaxanthin (0.35 mg/100 g FW). Structures of lutein, beta-carotene and violaxanthin were identified by LC-atmospheric pressure chemical ionization MS in positive ion mode, and by comparing the retention time and UV-vis spectral data with standards. Results from this study suggest the selected crops and agri-food industrial processing by-products of these can be a good source of free lutein. PMID:16242702

    Soil and sediment related research for terrestrial agri-environmental assessments requires accurate depth incremental sampling of soil and exposed sediment profiles. Existing coring equipment does not allow collecting soil/sediment increments at millimetre resolution. Therefore, the authors have designed an economic, portable, hand-operated surface soil/sediment sampler - the Fine Increment Soil Collector (FISC) - which allows extensive control of soil/sediment sampling process and easy recovery of the material collected by using a simple screw-thread extraction system. In comparison with existing sampling tools, the FISC has the following advantages and benefits: (i) it permits sampling of soil/sediment samples at the top of the profile; (ii) it is easy to adjust so as to collect soil/sediment at mm resolution; (iii) it is simple to operate by one single person; (iv) incremental samples can be performed in the field or at the laboratory; (v) it permits precise evaluation of bulk density at millimetre vertical resolution; and (vi) sample size can be tailored to analytical requirements. To illustrate the usefulness of the FISC in sampling soil and sediments for 7Be - a well-known cosmogenic soil tracer and fingerprinting tool - measurements, the sampler was tested in a forested soil located 45 km southeast of Vienna in Austria. The fine resolution increments of 7Be (i.e. 2.5 mm) affects directly the measurement of the 7Be total inventory but above all impacts the shape of the 7Be exponential profile which is needed to assess soil movement rates. The FISC can improve the determination of the depth distributions of other Fallout Radionuclides (FRN) - such as 137Cs, 210Pbexand239+240Pu - which are frequently used for soil erosion and sediment transport studies and/or sediment fingerprinting. Such a device also offers great potential to investigate FRN depth distributions associated with fallout events such as that associated with nuclear emergencies. Furthermore, prior

    Planning, delivery and monitoring of integrated environmental, social and economic outcomes from agri-environmental payments to land owners has rarely been attempted at a national scale. Wales has launched one of the most ambitious projects ever within the EU to frame both delivery of payments and ongoing integrated assessment of outcomes within an ecosystem framework. Payment and evaluation activities are running simultaneously, which when combined with scenario analysis from a suite of biophysical and landscape quality models, allows for adaptive management as the scheme progresses. Social and economic benefits and constraints to uptake of scheme measures and desired outcomes are embedded within the project to ensure benefits to the wider population are realised. Initial modelling results in the first year of the monitoring and evaluation programme quantified potential benefits from a range of management options offered under the subsidy scheme. At a national scale these ranged from: 1 to 9% improvement in flood mitigation; 5 to 10% reduction in greenhouse gas emissions; increased accessible land for 'generic' broadleaf focal species by 3 to 12%, increased national carbon storage by ca. 0.4%, and reduced eroded soil and phosphorus delivery by up to 15% due to reduced connectivity of erodible land to rivers and lakes. Results at local / farm scales could be as high as 80% in some locations. A 75% improvement in habitat for selected 21 indicator plant species was also projected. The inter-dependency between outcomes is being explored through a major integrated rolling monitoring programme taking co-located measurements of soil, vegetation, landuse, soils, water, birds and pollinators, GHG fluxes, landscape and historic features and farmer / landowner surveys using a stratified sampling approach across the country. In addition to scenario analysis, modelling is being used to upscale and integrate findings and to explore the extent of co-benefits and trade

    The Val d'Agri basin in the Apennines extensional belt hosts the largest oilfield in onshore Europe. High-quality recordings from a temporary dense network unravel a swarm of 111 small-magnitude events (ML ≤ 1.8) occurred in June 2006 during the first stage of wastewater injection into a high-rate well. 3D absolute locations and high-precision relative locations define a high-angle fault located 1 km below the well inside fractured and saturated carbonates where wastewater is re-injected. Seismicity begins 3 hours after the initiation of injection. The seismicity rate strictly correlates with injection curves and temporal variations of elastic and anisotropic parameters. Seismicity is induced by rapid communication of pore pressure perturbations along a high permeability fault-zone favorably oriented with respect to the extensional stress field. The spatiotemporal distribution of events agrees with an isotropic hydraulic diffusivity of 0.8 m2/s, which corresponds to high permeability values on the order of 10-13 m2/s. Such high permeability values are coherent with hydraulic well-tests in the very productive hydrocarbon reservoir and with the presence of a widespread system of open and conductive fractures in the carbonates that strike NW-SE parallel to the maximum horizontal stress of the extensional stress regime. Over the following 8 years, 235 events (ML ≤ 2.2) were recorded within 5 km of the disposal well by permanent stations of the local operator network and of Istituto Nazionale di Geofisica e Vulcanologia. Accurate 3D locations concentrate on the fault and unravel that after June 2006 micro-seismicity migrated upwards and downwards along the fault measuring 5-km along dip. Subsurface data show that the fault is a pre-existing blind back-thrust of an inherited fold-thrust system developed in the carbonate reservoir during Pliocene-Early Pleistocene. The seismicity rate correlates with short-term increases in injection pressure of the disposal well.

    las compañías pero que no se traduce necesariamente en desarrollo social. Esta situación indica la exclusión de los circuitos globales como una estrategia democrática de desarrollo socio-económico.This article is aimed at examining the main characteristics of the process of globalization of the agri-food system regarding Latin America's socioeconomic development. The vast literature on globalization is summarized in three distinct groups. Radical neoliberals argue that globalization represents the necessary prescription for advancing the world socioeconomic development. Interventionist-centrists sustain that even though market dynamics have a central role, it is not possible to keep social and economic balance without state intervention. The third group criticizes globalization and defines it as a contradictory system that widens the gap between rich and poor countries and the gap between social classes within individual countries. Based on three case studies, this work examines three hypotheses generated by this debate. The first one concerns the workings of free market; the second one refers to the state's power and role; and the third one is related to the issue of democracy. The conclusion is that the market is strongly conditioned by transnational corporations and their actions negatively affect several social groups. It is also argued that the state keeps important powers, which, however, are being used to advance transnational corporations' interests, thus creating favorable conditions to capital's hypermobility. Regarding the third subject it is pointed out that globalization restrains popular participation in decision-making processes but simultaneously generates resistance and social mobilization. The conclusions underline that globalization generates a crisis in national development programs since economic growth is more based on the regional-global axis. It is also said that inclusion in global circles tends to increase benefits to companies but that

    It is urgently necessary for the Philippines, which has no promising energy source to replace imported oil and lacks hard currencies, to reduce dependence on oil. The country, consisting of a number of islands, has faced many difficulties in construction of large-scale power transmission grids covering wide areas, which greatly retard development of local industries and dissemination of electricity. Therefore, great expectations have been placed on the techniques this project plans to develop for utilization of wastes as the energy source. This 5-year project (FY 1990 to 1994) is aimed at joint research and development of (thermal decomposition/gasification and power generation system) for transforming large quantities of wood-wastes/agri-wastes left unutilized into electric power, in which thermal decomposition/gasification of the wastes is combined with gas engine/power generator systems, and thereby to establish the systems suitable for the developing country. The major R and D results obtained in FY 1990 as the initial year include negotiations with the Philippines, on-the-spot surveys for the demonstration plant sites and conditions, and conceptual designs of the demonstration plant.

    The agricultural technology diffusion is a complex system which is composed of technology centers, technology receivers and diffusion environment. The diffusion environment is a multidimensional synthesis, and as a external influence factor of the agricultural technology diffusion, it plays an important role in the diffusion. The development level and the spatial pattern effect the direction, speed and the mode of the diffusion. Therefore, the special analysis of the agricultural technology diffusion environment for the specific regions is meaningful to the understanding of these regions' agri-technique diffusion. The quantification and evaluation of the agri-technique diffusion environment can provide many beneficial references to the diffusion. This paper take the 169 counties in Shaanxi-Gan su-Ningxia region as the research objects, choose the 12 main indices, and use the principal component analysis to description the gap among the 169 counties. Then uses the spatial analysis provided by GeoDa to reveal the spatial char acteristics. The result shows that there are three main factors affect the agri-technique diffusion environment, includes the agriculture output efficiency and cultural atmosphere, agricultural resources conditions, agricultural input level; the agri-technique diffusion environment in 169 counties has significant differences and geographical spatial agglomeration; "hot-spots" counties concentrate on Guanzhong region, Hexi corridor and the irrigated area by Yellow River in north Ningxia province, the most "cold-spots" counties are located in middle and north part of Gansu province; the space differentiations of the environment of agri-technique diffusion of Northwest China are mainly caused by the spatial differences of the natural conditions and the social economy and culture. The results of the study tell us that we must do something to optimize the agri-technique diffusion environment: using the space connection to achieve collaborative

    Full Text Available Durante o processamento da matéria-prima da indústria sucroalcooleira, gerase grande quantidade de efluentes com qualidades que impossibilitam seu lançamento em corpos de água sem o tratamento prévio. A biorremediação é usada para decompor resíduos orgânicos até um estado inócuo ou abaixo da concentração limite da legislação, tendo os fungos papel muito importante nessa estratégia por secretarem enzimas hidrolíticas. Neste trabalho, avaliou-se o comportamento de fungos isolados de resíduos da estação de tratamento de efluentes de uma indústria sucroalcooleira frente à degradação de fenóis como o ácido tânico e de outros compostos de efluentes agroindustriais suplementados com nutrientes específicos. Dentre diferentes isolados, aqueles identificados como Aspergillus sp.e Cladosporium sp. apresentaram as melhores taxas de produção de enzimas degradadoras de ácido tânico, como a lacase, por exemplo, enquanto Mucor sp. foi o que melhor removeu a Demanda Química de Oxigênio (DQO e o conteúdo de fenóis totais, seguido por Cladosporium sp., Phanerochaeta chrysosporium e Geotrichum candidum.During the processing of raw materials from the sugar-alcohol industry, large quantities of wastewater is produced, which is inappropriate to release into water bodies without previous suitable treatment. The bioremediation is used to decompose organic waste until an innocuous condition or to a concentration below the limit under legislation; moreover fungi have very important role in this strategy due to the secretion of hydrolytic enzymes. In the present study, we evaluated the behavior of fungi isolated from residuals of the waste treatment station from a sugar-alcohol industry in faceto the phenols degradation, as tannic acid and other compounds of agri-industrial wastewater supplemented with specific nutrients. Among different fungi, those identified as Aspergillus sp. and Cladosporium sp. presented the best rates of

    Full Text Available A realidade competitiva vivenciada pelas empresas desestimula que elas ajam de forma isolada, requerendo ações coordenadas com outras empresas da mesma cadeia. Por essa razão, a busca pela coordenação de cadeias de produção visando à melhoria da qualidade do produto e à redução dos custos associados às perdas da produção e aos custos de transação está se tornando uma prática mais comumente adotada por empresas que partilham o objetivo de adicionar valor e competitividade ao produto final da cadeia. Este artigo aborda o problema da coordenação da qualidade em cadeias de produção agroalimentares (CPAs. Com base em conceitos da revisão bibliográfica e de evidências empíricas, são propostos uma Estrutura (ECQ - Estrutura para Coordenação da Qualidade e um Método (MCQ - Método para Coordenação da Qualidade para a coordenação da qualidade em CPAs. Em algumas cadeias, a implementação da ECQ/MCQ vem sendo ilustrada bem como usada como alternativa técnica possível e confiável para coordenar e garantir a qualidade do produto final.Today's reality prevents companies in general from planning or acting alone, requiring that they engage in coordinated action with others in the same production chain. For this reason, production chain coordination to improve product quality and reduction of production wastes and transactions costs is becoming a widespread practice to promote integrated management of companies that share the goal of adding value to the chain's final product. This paper discusses the problem of quality in agri-food supply chains (ASC. Based on wide bibliography review, a structure (ECQ and a method (MCQ are proposed for the quality coordination in ASC. In some chains the ECQ/MCQ implementation has been studied and used as a possible and liable technical alternative to coordinate and assure the final product quality.

In view of the lack of risk information and the fuzziness of risk attributes, the triangular fuzzy number was used to express expert semantic judgment and a kind of risk source analysis method was therefore established based on the triangular fuzzy number of agricultural products supply chain. Finally, a nu-merical example was used to verify the method. The result showed that this method is feasible and practical in estab-lish the risk sources model of agri-product supply chain based on internet of things.

    Due to the effect of uncertain factors such as seasonal weather, the output of agriculture produc-tion is uncertain given certain agricultural inputs. This paper addresses the issue of coordinating agri-food chain with perishable goods by revenue-sharing contract when both output and demand random factor are uniform distribution. Under revenue-sharing contract, a supplier decides on agricultural input (e) and de-liveries all goods with a price (ω) lower than its production cost per unit to the retailer while a retailer de-cides on the retail price (p) and return 1-Φ share (percentage) of its revenue to the supplier. Under such a contract, we analyze the basis of coordination of the chain and provide the relationship between ω and Φ as well as the range of Φ. A numerical example illustrates the correctness of our analysis. The results show that the revenue-sharing contract is able to coordinate the agri-food chain effectively and the optimal deci-sions of p and e are closely related to the demand price elasticity. The results also show the range of Φ is widen when the expected output increases.%生鲜农产品生产受季节性和天气等影响,投入一定农资后产出呈随机分布.本文考虑产出和需求扰动服从均匀分布情形下,单个生产商和零售商的供应链协调问题.在收益共享合同模式下,生产商决定农资投入数(e)并将单一产品以低于生产成本的价格(ω)全部出售给零售商,零售商制定销售价格(p)进行销售并支付约定比例(1-Φ)的收益补偿生产商.在分析供应链协调的条件后,说明了合同参数ω与Φ的关系和Φ设定范围.研究结果表明,收益共享合同能有效地协调供应链,且协调的p和e与需求价格弹性有关;并且Φ取值范围随影响产出的随机变量的期望值变大而增大.最后以数值箅例说明了分析结果的正确性.

    Full Text Available O paradigma da bioeconomia pode ser descrito como o conjunto das atividades econômicas que captam o valor latente em processos biológicos e nos biorecursos renováveis, para produzir melhores condições de saúde, além de crescimento e desenvolvimento sustentáveis. Este artigo faz uma revisão crítica do impacto da bioeconomia emergente sobre o desenvolvimento rural. São descritas algumas das consequências do desenvolvimento rural bioeconômico, na esfera agroalimentar e da inovação regional baseada em uma definição específica -e, de nosso ponto de vista, fraca -de Modernização Ecológica. A questão central, então, é: quais são as bases conceituais, a força impulsora, as expressões empíricas e as implicações do desenvolvimento bioeconômico? Argumenta-se que, embora a bioeconomia faça duras cobranças em relação à sustentabilidade, também deixa lacunas, apresenta al-guns efeitos secundários negativos, tanto ambientais como sociais, e corre o risco de ser uma economia parcial. Sustentamos, ainda, que a trajetória do desenvolvimento ecoeconômico pode constituir uma boa alternativa para localidades particularmente vulneráveis que queiram aumentar sua resiliência.The bio-economic paradigm can be described as those economic activities which capture the latent value in biological processes and renewable bioresources to produce improved health and sustainable growth and development. This article is a critical review of the impact of the emerging bio-economy in rural development. It describes some of its consequences in the sphere of agri-food and regional innovation based on a specific -and in our opinion weak - definition of Ecological Modernization. The central question then is: what are the conceptual roots, driving forces, empirical expressions and implications of bio-economic development? We argue that although the bio-economy makes severe sustainability claims, it also shows some missing links, has some negative

    Full Text Available The aim of the paper is to highlight the positioning of the so-called Made in Italy agro-food exports in foreign markets considering global world tendencies as well as country specific trends. Besides, we aim at disentangling the role of product quality from price competition as a driver of competitive advantages.To these ends, the work combines two different methodologies, applied in three steps. First, we estimate the elasticities of Italian exports, with respect to world imports, Italian export prices and the competitors’ prices. Second, an index of the sophistication of exports’ flows that captures the role of quality in global competition is calculated. Third, the estimated elasticities are compared with the changes in the sophistication levels.Results allow for product-specific trends to stem out from the overall picture. Exports’ performance varies according to the type of product and to the degree of market completion. Although, the Made In Italy aggregate seems overall competitive, the analysis pinpoints some drawbacks in the positioning of some products in the world arena. Focus on wine and on olive oil, two major Italian exporting sectors, helps in understanding the potential of the joint methodology adopted.

    2011-02-01

    Full Text Available A general consensus on bio-energy and renewable energetic sources is expressed by modern societies; at the same time, some concerns and uncertainties are related to the actual ecological and environmental standards that these new technologies are able to fulfill. The overall energy demand is permanently rising as the economic growth spread through new developing countries. The consciousness about the limited petroleum availability and the negative environmental consequences related to fossil fuels exploitation, inevitably calls for a new global energy model based on a drastic improvement on energy use efficiency, energy savings and renewables. On this respect, biomass could play an important role to meet these new constraints and requirements. The development of bio-energy needs a reliable biomass availability, a well organized and integrated chain-supply and reasonable costs of the biomass feedstock in order to be competitive with respect to conventional fossil-fuels. Different productive and distributive chain-supply can be depicted, at the large as well as at the local-scale; pros and cons can be identified for both, but locally produced bio-energy and “distributed” energy generation is mostly favored by general society and some stakeholders; it seems to better support landowners, rural economy and local market; at the same time, the environmental benefits seems to be higher. Rigorous evaluation procedures, such as “Life Cycle Assessment”, must be ordinarily implemented to proper compare such alternatives with each other and choose the one that fits better.

    , these traditional villages have a strong local characteristic and a wealth of knowledge about local culture. They are valuable asset of humans with a unique living concept, cultural traditions and science and technology, which should be appropriately protected. After long-term agricultural development, Dong villages exhibit the cultural characteristics of agriculture. The agri-cultural connotation of traditional Dong villages were analyzed in this paper. The location of the Dong villages is closely related to the production of the Dong ancestors, e.g., the center of the Dong villages' structure is the Drum Tower, which is a reflection of traditional forms of social organization, the layout of the village and building construction is affected by the agriculture, and the shape of national construction, decoration and construction process have a close relationship with the agriculture. Development measures of the traditional Dong villages were proposed. It is important to involve the village as a part of the cultural system of agriculture and the holistic protection and to seize the opportunity of “GIAHS” project, for example, considering tourism as the dynamic conservation approach, and improving the livelihood of the local community.

    The challenges of food production are enormous and will be even more pressing in order to meet the growing need for food worldwide. It must therefore be at the center of international policy the theme of food and encourage a process of development and intensification of research and innovation policies, to address an epochal challenge like the one we face. The paradigm to be used and what the Green Economy in a multidisciplinary perspective, an integrated approach that considers not only the primary production of food, linked to agriculture, its industrial processing and distribution, but also the energy issue, the environment and the territory with its cultural and social values, nutrition, nutrition and health, consumer eating habits. A new approach to sustainable production of food that has interest and impact both to the general public, both to the world of production, industrial and scientific. The new idea is based on the possibility of treating the issue as an integrated system based on a finite number of sub-systems (agriculture, environment, food security, water, health, energy, infrastructure, economy etc.), To manage in a coordinated way to address the future challenges we have ahead, pursuing five objectives. Objective 1: Maintains the agricultural land available for food production Objective 2: Increasing agricultural production and reduce losses Objective 3: Making the most efficient and sustainable agriculture Objective 4: To adopt sustainable consumption patterns and reduce waste Objective 5 : Ensuring quality and food safety

    2015-11-01

    A landslide, to the west of Montemurro (a small village in southern Italy), has recently caused damage to buildings and other infrastructure in an urbanized area; as a result the development of new economic activities has been prohibited. The landslide phenomenon started in the last century and has been studied since the 1990s using classical geotechnical methods; however the sliding body continues to move. This paper presents the results of a study carried out using field surveys, geognostic investigations and TDR (time domain reflectometry) measurements in order to reconstruct the stratigraphy of the sediments involved and to further understand the geological and geomorphological context of the slope. This study is part of a larger multidisciplinary project, the results of which will also be presented in this paper. The landslide (rotational slide in the upper sector, developing into a translational slide in the lower part) affects Quaternary continental clastic deposits resting on a bedrock formed by Tertiary siliciclastic sediments of the Gorgoglione Flysch. TDR measurements did not show any significant movement during the period monitored (January 2013-January 2014). Slip zone geometries were hypothesized using inclinometric measurements taken from previous studies, stratigraphic data and geomorphological interpretations of topographic scarps. Feedback from monitoring will confirm this hypothesis.

    2010-07-01

    Activities in British Columbia's Fraser Valley generate an estimated 3 million tones of agriculture and food wastes annually, of which 85 per cent are readily available for anaerobic digestion. The potential for energy generation from biogas through anaerobic digestion is approximately 30 MW. On-farm manure-based systems represent the most likely scenario for the development of anaerobic digestion in British Columbia in the near future. Off-farm food processing wastes may be an alternative option to large centralized industrial complexes. Odour control, pathogen reduction, improved water quality, reduced greenhouse gas emissions and reduced landfill usage are among the environmental benefits of anaerobic digestion. The economical benefits include power and heat generation, biogas upgrading, and further processing of the residues to produce compost or animal bedding. This paper described a newly developed anaerobic digestion (AD) calculator that helps users regarding their investment decision in AD facilities. The calculator classifies various technology options into several major types of AD systems. It also constructs kinetic and economic models for these systems and provides a fair estimation on biogas yield, digester volume, capital cost and annual income. The calculator takes into consideration factors such as the degradability of wastes with different compositions and different operating parameters.

    Full Text Available  The study explores local food as a marketing opportunity for small food producers and identifies barriers to development. Research was conducted primarily through depth interviews, supplemented by a survey of food marketing group members in North-West England. The results of this local study were consistent with national survey data showing increasing consumer interest in food provenance, traceability and support for the local economy. Lack of an official and recognised definition of the term "local food" hindered marketing. Restricted access to finance and the burden of regulations were identified as barriers. Further, small business success was subjective and difficult to identify, since goals may be based on sustaining a lifestyle rather than profit.

    Full Text Available With the globalization of trade, people have become enlightened and demanding consumers as regards the origin of their food and the environment in which it is produced. The concept of geotraceability described in this article responds to that requirement by combining geographical information with conventional traceability data. The inclusion of geographical information relating to the environment of the production plots is based not only on exploiting some functionalities of spatial analysis tools that exist in geographical information systems (GIS but also on developing specific tools such as a geoidentifier and geoindicators. This article also describes the characteristics and methods of implementing a geographical information management system linked with traceability information. Lastly, the potential for using geotraceability systems in supply chains is analyzed, in particular for consumer warnings in cases of food crisis and assistance for certification of differentiated quality agricultural products.

    Full Text Available This study evaluates the effects of environmental variables on traditional and alternative agroecosystems in three Ejidos (communal lands in the Chiapas rainforest in Mexico. The tests occurred within two seasonal agricultural cycles. In spring-summer, experiments were performed with the traditional slash, fell and burn (S-F-B system, no-burn systems and rotating systems with Mucuna deeringiana Bort., and in the autumn-winter agricultural cycle, three no-burn systems were compared to evaluate the effect of alternative sowing with corn (no-burn and topological modification of sowing. The results show a high floristic diversity in the study area (SS = 4 - 23%, with no significant differences among the systems evaluated. In the first cycle, the analysis of the agronomical variables of the corn indicated better properties in the fallowing systems, with an average yield of 1950 kg ha‑1, but there was variation related to the number of years left fallow. In the second cycle, the yields were positive for the alternative technology (average yield 3100 kg ha‑1. The traditional S-F-B systems had reduced pests and increased organic matter and soil phosphorous content. These results are the consequence of fallow periods and adaptation to the environment; thus, this practice in the Chiapas rainforest constitutes an ethnocultural reality, which is unlikely to change in the near future if the agrosystems are managed based on historical principles.

    Italian Food Processing Section includes primary sector (agriculture, fishing and farming), secondary industry and service sector (trade, transport and marketing). The whole process is structured in a sequence of production structures, which constitute a die. The most important food processing dies are fruit and vegetable, cereals, wine, oil, bovine, swine and avian breeding, fishing, milk and cheese. Every die presents very different production cycles, jobs and working professionals. Considering the heterogeneity of food processing dies, all occupational risk factors, such as chemical, biological, physical, ergonomic, psychosocial and injuries risks, are very frequent in such working activities. In a pilot study carried out in the province of Foggia (Apulia, Southern Italy) we showed that the major perceived risk factors where dust and physical overload in the cereal-pasta processing die, and noise and awkward postures in olive-oil die. However, perceived risk factors are biased by low risk perception due to poor information about health occupational hazards, this representing an important health safety problem. For this reason, the activity of preventive authorities at various levels is highly recommended.

  15. Seed preferences by rodents in the agri-environment and implications for biological weed control.

    Fischer, Christina; Türke, Manfred

    2016-08-01

    Post-dispersal seed predation and endozoochorous seed dispersal are two antagonistic processes in relation to plant recruitment, but rely on similar preconditions such as feeding behavior of seed consumers and seed traits. In agricultural landscapes, rodents are considered important seed predators, thereby potentially providing regulating ecosystem services in terms of biological weed control. However, their potential to disperse seeds endozoochorously is largely unknown. We exposed seeds of arable plant species with different seed traits (seed weight, nutrient content) and different Red List status in an experimental rye field and assessed seed removal by rodents. In a complementary laboratory experiment, consumption rates, feeding preferences, and potential endozoochory by two vole species (Microtus arvalis and Myodes glareolus) were tested. Seed consumption by rodents after 24 h was 35% in the field and 90% in the laboratory. Both vole species preferred nutrient-rich over nutrient-poor seeds and M. glareolus further preferred light over heavy seeds and seeds of common over those of endangered plants. Endozoochory by voles could be neglected for all tested plant species as no seeds germinated, and only few intact seeds could be retrieved from feces. Synthesis and applications. Our results suggest that voles can provide regulating services in agricultural landscapes by depleting the seed shadow of weeds, rather than facilitating plant recruitment by endozoochory. In the laboratory, endangered arable plants were less preferred by voles than noxious weeds, and thus, our results provide implications for seed choice in restoration approaches. However, other factors such as seed and predator densities need to be taken into account to reliably predict the impact of rodents on the seed fate of arable plants. PMID:27547355

  16. Research for the innovation of the agri-food system in international cooperation

    2012-08-01

    Full Text Available In the last few decades, characterized by intense environmental, landscape and socio-economic-financial changes, unexpected issues concerning the primary sector are arising and asks to researchers an urgent and deep reformulation both of the conceptual and technological tools used in the applied research. The concept of innovation is now radically changed, starting from a prevailing formula of linear top-down technology transfer, which has characterized the green revolution of the 1960s, to nowadays approach characterized by the innovation of a complex system, aimed at creating sustainable and shared opportunities through economic and institutional development. Those who now work in public or private bodies oriented to research for innovation are struggling to maintain their specific study area, but within integrated schemes where technical and scientific aspects are in interaction with organizational, institutional and political issues. Innovation can tackle several issues: new products, new technologies, new markets, new procedures (institutions and new policies. The series of scientific and conceptual tools framed into the Agro-ecology domain seems appropriate to plan development initiatives of which the primary objective is ensuring a sustainable management of all the resources involved in agricultural production processes, while promoting food security and sovereignty, as well as protecting the rural landscape. By studying a target agro-ecosystem it is possible to identify and characterize the relationships between both the internal components and the system structures and functions at different levels of complexity of plot, farm and country, without neglecting the interactions among scientific, technological and socio-economic factors, and ultimately tending towards a science aimed at conflict resolution. Given the challenges that agricultural development is going to face in the next decades, it is indeed essential to support the planning and implementation of sound agro-ecological policies through an appropriate set of advanced tools. Particularly, a key aspect to empower all the stakeholders involved in the research, development, dissemination and application of new methods and technologies is the identification of information and communication systems that farmers and policy makers need in order to cope with fast-changing conditions in a complex system. University and research centers can act as institutional facilitators of dialogue and development policies among different stakeholders, catalyzing participation and promoting participatory problem-solving strategies for agricultural development and cooperation.

    Full Text Available The paper aims at the assessment of the main effects of signing the Association Agreement on the Moldovan agricultural sector, while examining its reaction, if the Republic of Moldova would have opted for its integration in the Customs Union - Russian Federation, Belarus, and Kazakhstan. During the period 2010-2013, Republic of Moldova launched a number of trade policy development initiatives in order to ensure a more facilitating legal framework for the economic and trade relations with the key external partners. An agreement on the establishment of a free trade area in the CIS was signed in this period. Similarly, Republic of Moldova started negotiating the Association Agreement with the European Union, which was signed in June this year and has as component part the Deep and Comprehensive Free Trade Agreement (DCFTA. The paper reveals that the signing of the Association Agreement with the EU could serve as instrument to stimulate the agricultural sector, but the DCFTA establishment will present some challenges, which are to be properly addressed, in order to exclude their turning into risks.

    Full Text Available Considerations on assessing the dynamics of expenditure, which are directed from the national budget and EU, their proportions and selected interdependencies occurring in the implementation of agricultural policy in Poland in the long run, ie in 1996- -2012 (17 years in the period before and after accession to the EU are discussed. The study is carried out at several levels. One of them assesses the relationship of expenditure on the agricultural sector relative to total budgetary expenditure. The authors also present share expenses with funds from the EU's total budget in Polish agriculture, which allowed to determine the relationship between the EU and national funding budgetary objectives in agricultural policy in Poland. Based on these observations it was possible to determine the status of the agricultural budget in the light of the national budget before and after accession to the EU.

  3. New products from the agri-food industry: the return of n-3 fatty acids into the food supply.

    Science.gov (United States)

    Simopoulos, A P

    1999-01-01

    The meat from animals and fish in the wild, chicken eggs produced under complete natural conditions, and wild plants contain higher amounts of n-3 fatty acids compared to domesticated or cultivated ones. The composition of meats, fish, and eggs is dependent on animal feed. Fish-meal, flax, and n-3 from algae in animal feeds increase the n-3 fatty acid content of egg yolks and lead to the availability of n-3 fatty acid-enriched eggs in the marketplace. Research is ongoing for the production of n-3 fatty acid-enriched products from poultry, beef, lamb, pork, milk, bakery products, etc. In the case of n-3 fatty acid-enriched eggs, the egg under complete natural conditions (Greek or Ampelistra egg) can serve as a guide for proper composition. Otherwise, the amount of n-3 fatty acids is determined by the organoleptic properties of the products. It is essential in the process of returning the n-3 fatty acids into the food supply that the balance of n-6/n-3 fatty acids in the diet that existed during evolution is maintained. Clinical investigations confirm the importance of n-3 fatty acids for normal function during growth and development and in the modulation of chronic diseases. The availability of n-3 fatty acid-enriched products should lead to improvements in the food supply. Pregnant and lactating women and infants should benefit since their diet is deficient in n-3 fatty acids, especially for the vegetarians among them. Studies with n-3-enriched eggs lower cholesterol levels, platelet aggregation, and blood pressure. Since cardiovascular disease, hypertension, and autoimmune, allergic, and neurological disorders appear to respond to n-3 fatty acid supplementation, a diet balanced in n-3 and n-6 fatty acids consistent with the diet during human evolution should decrease or delay their manifestation.

    2011-06-01

    This forum response adds a conceptualization of harmony to Dopico and Vázquez' investigation of pedagogy that combines citizen science, environmental and cross-cultural research, and service-learning. Placing many appropriate and significant aspects of culturally situated science education in an authentically relational context beyond the classroom, this paper calls attention to insightful contributions and new directions for research, such as the process of inducing or eluding nihilism regarding ecological issues. How can such a question be researched effectively in order to learn about the family of pedagogies emerging in response to the need for more ecologically conscious and relationally authentic teaching across many disciplines? In this paper, I use a Vygotskian framework and an abbreviated case study of agricultural service-learning from my research, drawing attention to the importance of students' culturally-mediated construction of setting as they interact in older and newer ways.

    Full Text Available Proton Transfer Reaction Mass Spectrometry (PTR-MS has evolved in the last decade as a fast and high sensitivity sensor for the real-time monitoring of volatile compounds. Its applications range from environmental sciences to medical sciences, from food technology to bioprocess monitoring. Italian scientists and institutions participated from the very beginning in fundamental and applied research aiming at exploiting the potentialities of this technique and providing relevant methodological advances and new fundamental indications. In this review we describe this activity on the basis of the available literature. The Italian scientific community has been active mostly in food science and technology, plant physiology and environmental studies and also pioneered the applications of the recently released PTR-ToF-MS (Proton Transfer Reaction-Time of Flight-Mass Spectrometry in food science and in plant physiology. In the very last years new results related to bioprocess monitoring and health science have been published as well. PTR-MS data analysis, particularly in the case of the ToF based version, and the application of advanced chemometrics and data mining are also aspects characterising the activity of the Italian community.

    Directory of Open Access Journals (Sweden)

    Samir Mili

    2016-08-01

    Full Text Available This contribution explores the buyer side of the value chains of the main agricultural products exported from the Mediterranean Partner Countries (MPCs to the EU, taking Spain as an explorative case study in the broader European context. It draws on the Global Value Chain (GVC approach to provide new survey-based evidence for better profiling the opportunities and constraints for EU trade for orange, strawberry, tomato and olive oil imported from Morocco, Tunisia, Egypt and Turkey. The approach used complements inquiries using quantitative trade models usually based on aggregate sectoral level. Results show differences depending on the product and the country studied. There are in all cases multiple challenges to be solved at the origin of the value chain including better chain organization, further transparency and security, improvement in infrastructure and logistics, keeping transaction costs manageable at the same time. Consumer preferences in buyer markets when sourcing must be taken on the first place. The findings can have relevant policy implications in terms of prospective Euro-Mediterranean Partnership Agreements on agriculture and food.

    2016-07-01

    The growing awareness of the relevance of food composition for human health has increased the interest of the inclusion of high proportions of fruits and vegetables in diets. To reach the objective of more balanced diets, an increased consumption of legumes, which constitutes a sustainable source of essential nutrients, particularly low-cost protein, is of special relevance. However, the consumption of legumes also entails some constraints that need to be addressed to avoid a deleterious impact on consumers' wellbeing and health. The value of legumes as a source of nutrients depends on a plethora of factors, including genetic characteristics, agro-climatic conditions, and postharvest management that modulate the dietary effect of edible seeds and vegetative material. Thus, more comprehensive information regarding composition, especially their nutritional and anti-nutritional compounds, digestibility, and alternative processing procedures is essential. These were the challenges to write this review, which focusses on the nutritional and anti-nutritional composition of Vigna unguiculata L. Walp, an emerging crop all over the world intended to provide a rational support for the development of valuable foods and feeds of increased commercial value. © 2016 Society of Chemical Industry.

    中国农产品流通体系内生于我国经济社会发展、小农经济和流通体制快速变革之中,也受到全球化、信息化等非传统因素影响。在这样的双重趋势下必然出现产销对接困难、市场秩序混乱、标准化规范化落后、宏观调控政策不到位等众多问题,这些问题又与生产环节、公益性批发市场、信息服务体系等几个关键节点密不可分。本文指出我国农产品流通体系建设必须适应我国经济社会及生产和消费模式,必须确保城乡人民生活需要,确保食品安全。建立起多元渠道并存、高效快捷安全的流通体系,政府应着重在改变观念、完善法律制度、做好规划、建立风险机制等方面进行完善。%China's agricultural products circulation system was born in the rapid development of economic and social and rapid transformation of smallholder agriculture and circulation system,and also affected by globalization,information technology and other non-traditional factors.Inevitablely in the double trends,many issues appeared such as production and marketing docking difficulties,market disorder,the backward standardization,and policy of macnoscopical adjusting controt does not reach the designated position and so on.The problems are inseparable with the key nodes such as production chain,public service wholesale markets,information service system.This article pointed out that China's agricultural products circulation system must adapt to China's economic and social production and consumption patterns,and it must satisfy that people's living standards necessary,and ensure food safety.In order to establish a multi-channel co-exist,efficient,safe and fast circulation system,the government should focus on the change of mindset,legal system improvement,good plan,and the establishment of risk mechanism.

The purpose of this study was to test different dyes (methylene blue, Azure B, Malachite Green and Crystal Violet, replacing the compound Poly R478 in the method of selection of phenol decomposer microorganisms in solid medium, and compare this activity of the mycoflora of effluents from sugar-alcohol industry, to the ones of other fungi acquired in official collection. The tested dyes proved to be excellent substitutes for Poly R478. The isolate that showed more intense decolorant activity than the diameter of its growth (Cladosporium sp. was then tested on two natural and one synthetic substrate (sugarcane bagasse, sawing wood, and methylene blue in liquid medium. This isolate removed highconcentrations of reducing sugars, proteins and total phenols, and reduced the COD in medium containing sawdust as natural substrate of phenols.

    Full Text Available Estimada em quase 8 milhões de hectares, a área cultivada com cana no País possui 60% de sua extensão dentro do Estado de São Paulo e encontra-se distribuída de maneira heterogênea pelo seu território. Em junho de 2007, a União da Indústria de Cana-de-Açúcar (UNICA e a SMA-SP assinaram um protocolo agroambiental para antecipar a extinção da queima da palha para 2014, em áreas com declividade inferior a 12%. O objetivo deste trabalho é realizar uma análise sobre a adesão dos municípios a este protocolo frente à dinâmica da prática da queima, utilizando técnicas de análise espacial. Foram selecionadas duas regiões de acordo com o índice de Moran, e realizadas análises sobre a mudança em relação à prática da queima no período entre 2006 e 2008. Matrizes de transição foram calculadas usando um modelo estacionário baseado na cadeia de Markov. Um segundo modelo, prescritivo, foi elaborado por indicação de especialistas. Os resultados apontaram que há clusters onde a adesão ao protocolo é maior, como no entorno de Barretos e Ribeirão Preto, enquanto em outras áreas a prática da queima ainda prevalece, como nas proximidades de Ourinhos e Jaú. No entanto, as análises feitas mostraram que há forte inclinação à adesão em todas as regiões de estudo.The estimated sugarcane cultivated area in Brazil lies around 8 million hectares, 60% of which are found within the state of São Paulo, unevenly scattered throughout its territory. In June 2007, the Sugarcane Industry Association (UNICA and SMA-SP signed an AgrI-Environment protocol, designed to anticipate the end of straw burning in areas with slope under 12% until 2014. The objective of this study is to perform an analysis of São Paulo municipalities' compliance with this protocol, considering the dynamics of burning practices, using spatial analysis techniques. Two study areas were selected according to Moran's index, and analyses on the harvesting practices changes during the period between 2006 and 2008 were performed. Transition matrices were calculated using a stationary model based on the Markov chain. A second model, prescriptive, was elaborated based on expert counseling. The results showed that there are clusters where the compliance with the protocol is higher, close to Barretos and Ribeirão Preto municipalities, while near Ourinhos and Jaú, the practice of burning is still regularly kept. However, the analysis showed that in all study areas there is a strong trend to reduce the pre-harvest burning.

Hence, mitigation measures are needed to reduce the nutrient loading from the arable land. Since Finland's accession to the EU in 1995 and the subsequent adaptation to its agri-environmental policy, constructed wetlands (CWs) have been one of the mitigation measures for which farmers may receive agri-environmental subsidies. The aim of th...

  18. Hydrological impact of rainwater harvesting in the Modder river basin of central South Africa

    2011-05-01

    Full Text Available Along the path of water flowing in a river basin are many water-related human interventions that modify the natural systems. Rainwater harvesting is one such intervention that involves harnessing of water in the upstream catchment. Increased water usage at upstream level is an issue of concern for downstream water availability to sustain ecosystem services. The upstream Modder River basin, located in a semi arid region in the central South Africa, is experiencing intermittent meteorological droughts causing water shortages for agriculture, livestock and domestic purpose. To address this problem a technique was developed for small scale farmers with the objective of harnessing rainwater for crop production. However, the hydrological impact of a wider adoption of this technique by farmers has not been well quantified. In this regard, the SWAT hydrological model was used to simulate the hydrological impact of such practices. The scenarios studied were: (1 Baseline scenario, based on the actual land use of 2000, which is dominated by pasture (combination of natural and some improved grass lands (PAST; (2 Partial conversion of Land use 2000 (PAST to conventional agriculture (Agri-CON; and (3 Partial conversion of Land use 2000 (PAST to in-field rainwater harvesting which was aimed at improving the precipitation use efficiency (Agri-IRWH.

    SWAT was calibrated using observed daily mean stream flow data of a sub-catchment (419 km2 in the study area. SWAT performed well in simulating the stream flow giving Nash and Sutcliffe (1970 efficiency index of 0.57 for the monthly stream flow calibration. The simulated water balance results showed that the highest peak mean monthly direct flow was obtained on Agri-CON land use (18 mm, followed by PAST (12 mm and Agri-IRWH land use (9 mm. These were 19 %, 13 % and 11 % of the mean annual rainfall, respectively. The Agri-IRWH scenario reduced direct flow by 38 % compared to Agri-CON. On the other

  20. Competitiveness of Small Farms and Innovative Food Supply Chains: The Role of Food Hubs in Creating Sustainable Regional and Local Food Systems

    Directory of Open Access Journals (Sweden)

    Giaime Berti

    2016-07-01

    Full Text Available Over the last decades, the economic, social and environmental sustainability of the conventional agri-food system has and continues to be contested within both academic and public institutions. For small farms, the unsustainability of the food system is even more serious; farms’ declining share of profit and the cost-price squeeze of commodity production has increased barriers to market access with the inevitable effect of agricultural abandonment. One way forward to respond to the existing conventional agri-food systems and to create a competitive or survival strategy for small family farms is the re-construction of regional and local agri-food systems, aligning with Kramer and Porter’s concept of shared value strategy. Through a critical literature review, this paper presents “regional and local food hubs” as innovative organizational arrangements capable of bridging structural holes in the agri-food markets between small producers and the consumers—individuals and families as well as big buyers. Food hubs respond to a supply chain (or supply network organizational strategy aiming at re-territorialising the agri-food systems through the construction of what in the economic literature are defined as values-based food supply chains.

    This paper describes the background, principles, concepts and methods of framing the technical regulation for edible safety requirement and assessment of agricultural genetically modified organisms (agri-GMOs) for Shenzhen Special Economic Zone in the People's Republic of China. It provides a set of systematic criteria for edible safety requirements and the assessment process for agri-GMOs. First, focusing on the degree of risk and impact of different agri-GMOs, we developed hazard grades for toxicity, allergenicity, anti-nutrition effects, and unintended effects and standards for the impact type of genetic manipulation. Second, for assessing edible safety, we developed indexes and standards for different hazard grades of recipient organisms, for the influence of types of genetic manipulation and hazard grades of agri-GMOs. To evaluate the applicability of these criteria and their congruency with other safety assessment systems for GMOs applied by related organizations all over the world, we selected some agri-GMOs (soybean, maize, potato, capsicum and yeast) as cases to put through our new assessment system, and compared our results with the previous assessments. It turned out that the result of each of the cases was congruent with the original assessment.

  4. Is breeding of farmland wading birds depressed by a combination of predator abundance and grazing?

    Science.gov (United States)

    van der Wal, R; Palmer, S C F

    2008-06-23

    Agri-environment schemes have been implemented across Europe to counter biodiversity loss in agricultural landscapes and halt the continual decline of farmland birds, including waders. Such schemes provide financial compensation for changes in agricultural practice, including livestock grazing regimes. Scheme uptake has been variable, partly because farmers believe that other factors, notably predation, are key to wader population declines. On the basis of wader breeding surveys across Shetland, UK, we show that predator density and livestock grazing, through reducing sward height, interact to influence territoriality and thereby are likely to affect wader breeding success. Our results appear to reflect views of both farmers and government agencies, which indicates that future agri-environment schemes would benefit from genuine stakeholder participation to maximize scheme uptake, implementation and beneficial effects on biodiversity. Our findings also imply that agri-environment schemes will reap the greatest benefits for waders through reducing stocking rate where avian predators are abundant. PMID:18381262

    2011-03-01

    Agri-environment schemes (AESs) have been implemented across EU member states in an attempt to reconcile agricultural production methods with protection of the environment and maintenance of the countryside. To determine the extent to which such policy objectives are being fulfilled, participating countries are obliged to monitor and evaluate the environmental, agricultural and socio-economic impacts of their AESs. However, few evaluations measure precise environmental outcomes and critically, there are no agreed methodologies to evaluate the benefits of particular agri-environmental measures, or to track the environmental consequences of changing agricultural practices. In response to these issues, the Agri-Environmental Footprint project developed a common methodology for assessing the environmental impact of European AES. The Agri-Environmental Footprint Index (AFI) is a farm-level, adaptable methodology that aggregates measurements of agri-environmental indicators based on Multi-Criteria Analysis (MCA) techniques. The method was developed specifically to allow assessment of differences in the environmental performance of farms according to participation in agri-environment schemes. The AFI methodology is constructed so that high values represent good environmental performance. This paper explores the use of the AFI methodology in combination with Farm Business Survey data collected in England for the Farm Accountancy Data Network (FADN), to test whether its use could be extended for the routine surveillance of environmental performance of farming systems using established data sources. Overall, the aim was to measure the environmental impact of three different types of agriculture (arable, lowland livestock and upland livestock) in England and to identify differences in AFI due to participation in agri-environment schemes. However, because farm size, farmer age, level of education and region are also likely to influence the environmental performance of a
