    Full Text Available A study to determine the impacts of farmers field schools (FFS on smallholders’ adoption of good agricultural practices in tea and to assess sustainability of smallholder tea production was conducted in the highlands of Kenya. Input-output data on tea management and on sustainability indicators (score 0-10 were collected from a sample of 120 FFS participants at the beginning of the study and from 60 randomly selected FFS participants and a comparison group of 60 non-FFS participants at the end of the study, 18 months later. The study showed that the smallholder tea systems are moving towards social sustainability and economic returns were positive. Sustainability indicator scores, for FFS members, increased by 4% from the base period. The FFS participants also attained a significantly higher level of farm sustainability, knowledge gains on good agricultural practices (GAP and higher yields and farm and tea income than their non-FFS counterparts. These findings indicate that FFS methodology had a positive contribution to enhancing farmer learning and adoption of good agricultural practices in tea and improved farmers’ livelihoods.

    Full Text Available Modern greenhouse production has been ~100% reliant on fossil fuels for all inputs (glazing, heating, fertilization, lighting, post-harvest. Recent innovations may reduce fossil fuel dependence but their effectiveness may not be thoroughly tested. To promote education in sustainable production, undergraduate students in Greenhouse Management class (Hort 3002W; University of Minnesota tested the effectiveness of two organic or ‘sustainable’ soilless media (Sunshine Natural and Organic Growing Mix, Sungro Metro-Mix Special Blend with a control (Sunshine LC8 Professional for crop production (height, leaf/flower number, yield and sensory evaluations (appearance, texture, taste, purchase of cucumbers (‘Big Burpless Hybrid’, ‘Sweet Burpless Hybrid’, basil (‘Opal Purple’, ‘Redleaf’, parsley (‘Green River’, ‘Extra Curled Dwarf’, ‘Hamburg’, and lettuce (Flying Saucer ‘Green’, ‘Red’. Significant differences between sustainable vs. control soils occurred for plant growth, depending on vegetative or reproductive traits, crops, and cultivars. These differences occasionally disappeared for sensory evaluation of edible components. In most crops, however, cultivars were highly significant factors. Undergraduate research can be used to provide directionality for future vegetable and herb plant breeding to focus on creating cultivars with increased yield and high consumer acceptance when grown in sustainable greenhouse soilless mixes.

    Building cognitive abilities often requires sustained engagement with effortful tasks. We demonstrate that beliefs about willpower-whether willpower is viewed as a limited or non-limited resource-impact sustained learning on a strenuous mental task. As predicted, beliefs about willpower did not affect accuracy or improvement during the initial phases of learning; however, participants who were led to view willpower as non-limited showed greater sustained learning over the full duration of the task. These findings highlight the interactive nature of motivational and cognitive processes: motivational factors can substantially affect people's ability to recruit their cognitive resources to sustain learning over time.

  4. Toward Sustainable Amino Acid Production.

    Science.gov (United States)

    Usuda, Yoshihiro; Hara, Yoshihiko; Kojima, Hiroyuki

    Because the global amino acid production industry has been growing steadily and is expected to grow even more in the future, efficient production by fermentation is of great importance from economic and sustainability viewpoints. Many systems biology technologies, such as genome breeding, omics analysis, metabolic flux analysis, and metabolic simulation, have been employed for the improvement of amino acid-producing strains of bacteria. Synthetic biological approaches have recently been applied to strain development. It is also important to use sustainable carbon sources, such as glycerol or pyrolytic sugars from cellulosic biomass, instead of conventional carbon sources, such as glucose or sucrose, which can be used as food. Furthermore, reduction of sub-raw substrates has been shown to lead to reduction of environmental burdens and cost. Recently, a new fermentation system for glutamate production under acidic pH was developed to decrease the amount of one sub-raw material, ammonium, for maintenance of culture pH. At the same time, the utilization of fermentation coproducts, such as cells, ammonium sulfate, and fermentation broth, is a useful approach to decrease waste. In this chapter, further perspectives for future amino acid fermentation from one-carbon compounds are described.

    Verain, Muriel C D; Dagevos, Hans; Antonides, Gerrit

    2015-08-01

    Food consumption is an important factor in shaping the sustainability of our food supply. The present paper empirically explores different types of sustainable food behaviors. A distinction between sustainable product choices and curtailment behavior has been investigated empirically and predictors of the two types of behavior have been identified. Respondents were classified into four segments based on their sustainable food behaviors: unsustainers, curtailers, product-oriented consumers, and sustainers. Significant differences between the segments were found with regard to food choice motives, personal and social norms, food involvement, subjective knowledge on sustainable food, ability to judge how sustainably a product has been produced and socio-demographics. It is concluded that distinguishing between behavioral strategies toward sustainable food consumption is important as consumer segments can be identified that differ both in their level of sustainable food consumption and in the type of behavior they employ.

    Full Text Available This article investigates dimensions and factors that according to the perception of business managers drive the market success of environmentally sustainable products. Initially, publications related to new products introduced to the market (with or without environmental focus were evaluated. Four complementary dimensions were identified as responsible for proper performance: (i Market Knowledge, (ii Interfunctional Collaboration, (iii Knowledge Integration Mechanisms, and (iv Generative Learning. Considering the above, an exploratory study following a qualitative approach was conducted with managers that work in the Brazilian market. For the choice of the respondents, some characteristics were considered, such as growth in the sector of activity where the organization works, and the area that they manage. Results lead to the validation and ranking of the factors and dimensions mentioned in the literature. They also allowed the identification of new factors as: technological domain, competitive price, quality, company's brand, and payback. Moreover, considering the variables described and the relationships established among them, it was inferred that technological domain can be considered as a dimension. This suggestion is based on the respondents' perception concerning "technological domain", such as: specialized people, research budget, and also budget for facilities and equipment. The study also shows deeper difference among practice areas than among sectors. Based on the list of factors that was generated, new studies are recommended to measure the impact of the factors and dimensions on the success of green products.

    The concept of ‘sustainability’ or ‘sustainable development’ is multi-dimensional, encompassing economic, environmental, social, and institutional governance aspects. The theoretical framework for this article on sustainability in poultry production is built on this multi-dimensional understanding...... of the concept, acknowledging that it is complex and contested. It is challenging to analyse or discuss the sustainability of one single sector within agriculture, because this sector is part of a global food system, and a systems approach is necessary. This article gives examples of elements which link to one...... throughout major parts of the world (economic aspects). There are numerous potential pathways for sustainable development of poultry production. Poultry are living, sentient animals that can be well integrated into many different types of urban and rural farming systems, where they benefit from...

  12. Primary production required to sustain global fisheries

    Pauly, D.; Christensen, V.

    1995-03-01

    THE mean of reported annual world fisheries catches for 1988-1991 (94.3 million t) was split into 39 species groups, to which fractional trophic levels, ranging from 1.0 (edible algae) to 4.2 (tunas), were assigned, based on 48 published trophic models, providing a global coverage of six major aquatic ecosystem types. The primary production required to sustain each group of species was then computed based on a mean energy transfer efficiency between trophic levels of 10%, a value that was reestimated rather than assumed. The primary production required to sustain the reported catches, plus 27 million t of discarded bycatch, amounted to 8.0% of global aquatic primary production, nearly four times the previous estimate. By ecosystem type, the requirements were only 2% for open ocean systems, but ranged from 24 to 35% in fresh water, upwelling and shelf systems, justifying current concerns for sustainability and biodiversity.

    The complex and unpredictable contexts in which environmental and development work take place require an adaptable, learning approach. Faith-based organizations (FBOs) play a significant role in sustainability work around the world, and provide a unique setting in which to study learning. This paper explores individual learning for sustainability within two FBOs engaged in sustainability work in Kenya. Learning outcomes covered a broad range of areas, including the sustainability framework, environment/conservation, skills, community work, interpersonal engagement, and personal and faith development. These outcomes were acquired through embodied experience and activity, facilitation by the workplace, interpersonal interaction, personal reflection, and Bible study and worship. Grounded categories were compared to learning domains and processes described by Mezirow's transformative learning theory. The findings indicate that for learning in the sustainability field, instrumental learning and embodied learning processes are particularly important, and consequently they require greater attention in the theory when applied in this field.

    2013-04-01

    A multi-product fish production planning produces simultaneously multi fish products from several classes of raw resources. The goal in sustainable production planning is to meet customer demand over a fixed time horizon divided into planning periods by optimizing the tradeoff between economic objectives such as production cost, waste processed cost, and customer satisfaction level. The major decisions are production and inventory levels for each product and the number of workforce in each planning period. In this paper we consider the management of small scale traditional business at North Sumatera Province which performs processing fish into several local seafood products. The inherent uncertainty of data (e.g. demand, fish availability), together with the sequential evolution of data over time leads the sustainable production planning problem to a nonlinear mixed-integer stochastic programming model. We use scenario generation based approach and feasible neighborhood search for solving the model.

    Sustainable biomass production on Marginal Lands (SEEMLA) The main objective of the H2020 funded EU project SEEMLA (acronym for Sustainable Exploitation of Biomass for Bioenergy from Marginal Lands in Europe) is the establishment of suitable innovative land-use strategies for a sustainable production of plant-based energy on marginal lands while improving general ecosystem services. The use of marginal lands (MagL) could contribute to the mitigation of the fast growing competition between traditional food production and production of renewable bio-resources on arable lands. SEEMLA focuses on the promotion of re-conversion of MagLs for the production of bioenergy through the direct involvement of farmers and forester, the strengthening of local small-scale supply chains, and the promotion of plantations of bioenergy plants on MagLs. Life cycle assessment is performed in order to analyse possible impacts on the environment. A soil quality rating tool is applied to define and classify MagL. Suitable perennial and woody bioenergy crops are selected to be grown in pilot areas in the partner countries Ukraine, Greece and Germany. SEEMLA is expected to contribute to an increasing demand of biomass for bioenergy production in order to meet the 2020 targets and beyond.

    Food production dominates land, water and fertilizer use and is a greenhouse gas source. In the United States, beef production is the main agricultural resource user overall, as well as per kcal or g of protein. Here, we offer a possible, non-unique, definition of 'sustainable' beef as that subsisting exclusively on grass and by-products, and quantify its expected US production as a function of pastureland use. Assuming today's pastureland characteristics, all of the pastureland that US beef currently use can sustainably deliver ≈45% of current production. Rewilding this pastureland's less productive half (≈135 million ha) can still deliver ≈43% of current beef production. In all considered scenarios, the ≈32 million ha of high-quality cropland that beef currently use are reallocated for plant-based food production. These plant items deliver 2- to 20-fold more calories and protein than the replaced beef and increase the delivery of protective nutrients, but deliver no B 12 . Increased deployment of rapid rotational grazing or grassland multi-purposing may increase beef production capacity.

    2017-08-01

    Faster and more efficient development of innovative and sustainable products has become the focus for manufacturing companies in order to remain competitive in today’s technologically driven world. Design concept evaluation which is the end of conceptual design is one of the most critical decision points. It relates to the final success of product development, because poor criteria assessment in design concept evaluation can rarely compensated at the later stages. Furthermore, consumers, investors, shareholders and even competitors are basing their decisions on what to buy or invest in, from whom, and also on what company report, and sustainability is one of a critical component. In this research, a new methodology of sustainability assessment in product development for Malaysian industry has been developed using integration of green project management, new scale of “Weighting criteria” and Rough-Grey Analysis. This method will help design engineers to improve the effectiveness and objectivity of the sustainable design concept evaluation, enable them to make better-informed decisions before finalising their choice and consequently create value to the company or industry. The new framework is expected to provide an alternative to existing methods.

    2016-11-01

    The instability in today's market and the ever increasing and emerging demands for mass customized and hybrid products by customers, are driving companies and decision makers to seek for cost effective and time efficient improvements in their product development process. Design concept evaluation which is the end of conceptual design is one of the most critical decision points in product development. It relates to the final success of product development, because poor criteria assessment in design concept evaluation can rarely compensated at the later stages. This has led to real pressure for the adaptation of new developmental architecture and operational parameters to remain competitive in the market. In this paper, a new integrated design concept evaluation based on fuzzy-technique for order preference by similarity to ideal solution (Fuzzy-TOPSIS) is presented, and it also attempts to incorporate sustainability practices in assessing the criteria. Prior to Fuzzy-TOPSIS, a new scale of “Weighting criteria” for survey process is developed to quantify the evaluation criteria. This method will help engineers to improve the effectiveness and objectivity of the sustainable product development. Case example from industry is presented to demonstrate the efficacy of the proposed methodology. The result of the example shows that the new integrated method provides an alternative to existing methods of design concept evaluation.

    2012-10-01

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

    Science.gov (United States)

    Smith, Pete; Gregory, Peter J

    2013-02-01

    One of the greatest challenges we face in the twenty-first century is to sustainably feed nine to ten billion people by 2050 while at the same time reducing environmental impact (e.g. greenhouse gas (GHG) emissions, biodiversity loss, land use change and loss of ecosystem services). To this end, food security must be delivered. According to the United Nations definition, 'food security exists when all people, at all times, have physical and economic access to sufficient, safe and nutritious food to meet their dietary needs and food preferences for an active and healthy life'. At the same time as delivering food security, we must also reduce the environmental impact of food production. Future climate change will make an impact upon food production. On the other hand, agriculture contributes up to about 30% of the anthropogenic GHG emissions that drive climate change. The aim of this review is to outline some of the likely impacts of climate change on agriculture, the mitigation measures available within agriculture to reduce GHG emissions and outlines the very significant challenge of feeding nine to ten billion people sustainably under a future climate, with reduced emissions of GHG. Each challenge is in itself enormous, requiring solutions that co-deliver on all aspects. We conclude that the status quo is not an option, and tinkering with the current production systems is unlikely to deliver the food and ecosystems services we need in the future; radical changes in production and consumption are likely to be required over the coming decades.

  20. Tailoring photocatalytic nanostructures for sustainable hydrogen production.

    Science.gov (United States)

    Cargnello, Matteo; Diroll, Benjamin T

    2014-01-07

    Photocatalysis is an important component for achieving sustainability in chemical transformations. It requires light absorption by a semiconductor and efficient extraction of the photogenerated electron-hole pairs to chemically active sites. One of the main problems in photocatalytic materials is to avoid electron-hole recombination following excitation. Tailored nanostructures offer a new way for achieving this goal by facilitating electron-hole separation. Nanoscaling of materials offers additional opportunities to generate unique photocatalysts that demonstrated novel light absorption, thermodynamic and kinetic properties. In this feature article we highlight some recent approaches towards the preparation of materials and nanostructures that showed improved activity for the sustainable production of hydrogen. This reaction has received much attention for the supply of future demand both for chemical industry and energy-related applications.

  1. Learning sustainability by developing a solar dryer for microalgae retrieval

    Directory of Open Access Journals (Sweden)

    Benedita Malheiro

    2016-01-01

    Full Text Available Excessive fossil fuel consumption is driving the search for alternative energy production solutions and, in particular, for sustainable sources of energy such as microalgae, from which biodiesel, among other useful compounds, can be obtained. After producing the microalgae, they must be harvested and dried. Existing drying solutions consume too much energy and are, therefore, expensive and unsustainable. The goal of this EPS@ISEP Spring 2013 project was to develop a solar microalgae dryer for the microalgae laboratory of ISEP. A multinational team of five students from distinct fields of study was responsible for designing and building the solar microalgae dryer prototype. The prototype includes a control system to ensure that the microalgae are not destroyed during the drying process. The solar microalgae dryer works as a distiller, extracting the excess water from the microalgae suspension. This paper details the design steps, the building technologies, the ethical and sustainable concerns and compares the prototype with existing solutions. The proposed sustainable microalgae drying process is competitive as far as energy usage is concerned. Finally, the project contributed to increase the team’s sustainable development awareness, active learning and motivation.

Still, people who attach importance to this type of information are niche on the Polish market.

  6. Sustainability Learning in Natural Resource Use and Management

    Directory of Open Access Journals (Sweden)

    J. David Tàbara

    2007-12-01

    Full Text Available We contribute to the normative discussion on sustainability learning and provide a theoretical integrative framework intended to underlie the main components and interrelations of what learning is required for social learning to become sustainability learning. We demonstrate how this framework has been operationalized in a participatory modeling interface to support processes of natural resource integrated assessment and management. The key modeling components of our view are: structure (S, energy and resources (E, information and knowledge (I, social-ecological change (C, and the size, thresholds, and connections of different social-ecological systems. Our approach attempts to overcome many of the cultural dualisms that exist in the way social and ecological systems are perceived and affect many of the most common definitions of sustainability. Our approach also emphasizes the issue of limits within a total social-ecological system and takes a multiscale, agent-based perspective. Sustainability learning is different from social learning insofar as not all of the outcomes of social learning processes necessarily improve what we consider as essential for the long-term sustainability of social-ecological systems, namely, the co-adaptive systemic capacity of agents to anticipate and deal with the unintended, undesired, and irreversible negative effects of development. Hence, the main difference of sustainability learning from social learning is the content of what is learned and the criteria used to assess such content; these are necessarily related to increasing the capacity of agents to manage, in an integrative and organic way, the total social-ecological system of which they form a part. The concept of sustainability learning and the SEIC social-ecological framework can be useful to assess and communicate the effectiveness of multiple agents to halt or reverse the destructive trends affecting the life-support systems upon which all humans

  13. System learning approach to assess sustainability and ...

    Science.gov (United States)

    This paper presents a methodology that combines the power of an Artificial Neural Network and Information Theory to forecast variables describing the condition of a regional system. The novelty and strength of this approach is in the application of Fisher information, a key method in Information Theory, to preserve trends in the historical data and prevent over fitting projections. The methodology was applied to demographic, environmental, food and energy consumption, and agricultural production in the San Luis Basin regional system in Colorado, U.S.A. These variables are important for tracking conditions in human and natural systems. However, available data are often so far out of date that they limit the ability to manage these systems. Results indicate that the approaches developed provide viable tools for forecasting outcomes with the aim of assisting management toward sustainable trends. This methodology is also applicable for modeling different scenarios in other dynamic systems. Indicators are indispensable for tracking conditions in human and natural systems, however, available data is sometimes far out of date and limit the ability to gauge system status. Techniques like regression and simulation are not sufficient because system characteristics have to be modeled ensuring over simplification of complex dynamics. This work presents a methodology combining the power of an Artificial Neural Network and Information Theory to capture patterns in a real dyna

  20. Soil quality: key for sustainable production

    Directory of Open Access Journals (Sweden)

    Stefano Mocali

    2011-02-01

    Full Text Available In the last few years several definitions of “soil quality” have been advanced, but among them the most appreciated is “the ability of soils to interact with the ecosystem in order to maintain the biological productivity, the environmental quality and to promote animal and vegetal health” as defined by Doran and Parkin in 1994. Many researchers place more emphasis on its conceptual meaning for land planning and farm management, while others consider that definition to be worth nothing in order to understand soil properties and the concept of soil quality looks like the concept of “to be suitable for”. For this reason a definition of “soil use” is needed. The food quality is characterized by several properties: the healthiness and the nutritional value, the amount of the production, the typicalness and organoleptic properties, etc.. A lot of these properties depend on environmental quality and, in particular, on soil quality. In fact soil represents the natural substrate for growth and productivity of most of the plants that live on the Hearth because they get all the essential nutritional elements from it for their own development; consequently each nutritional element present into the soil as bioavailable form for the plants is potentially destined to entry in the animal (and human food chain. In the quality process of food productive process it will be important to assure the best soil quality as possible, without any unwanted element (which will not be discussed in this note and with the right amount of fertility elements in order to guarantee the best production. In this paper the relationships between soil quality, soil biodiversity and crop sustainability will be discussed. Finally the concept of soil “biota” as nodal point for the environment regulation and the application of the indicators for soil quality will be discussed.

  1. Environmental sustainability: Understanding young adults' learning, thinking, and actions

    Science.gov (United States)

    Kola-Olusanya, Anthony O.

    This thesis explores the ways in which young-adults' environmental learning and experiences influence their decision to live sustainably. In particular, this thesis focuses on young adults' environmental and sustainability learning. It elaborates on young peoples' views about environmental and sustainability issues, such as climate change, the sources for their learning about these issues, and how young adults' learning encounters, in turn, affect their actions toward environmental protection and decision-making. Through a series of in-depth individual interviews with 18 young adults from three universities in southeastern Ontario, this qualitative study provides in-depth insight into young adults' understanding, learning experiences, and actions in relation to environmental and sustainability issues. Employing a Contextual Model of Learning framework the narratives of the young adults in this study are analyzed and discussed within three overlapping environmental learning contexts: personal, sociocultural, and physical settings. This framework allows for an examination of the complex interactions and relationships that shape how and where environmental learning occurs. The findings in this study suggest that the three overlapping learning contexts, that is the personal, sociocultural, and physical play an important role in shaping young adults' learning about environmental and sustainability issues. The data reveal that despite the unavailability or near-absence of environmental studies and education within the formal school curriculum (particularly at the elementary and high school levels), the young adults rely on other locations for learning, such as the internet, environmental non-governmental organisations (ENGOs), television, and family. In light of this, the research participants suggest the re-introduction of environmental programs and content in the school curriculum. Finally, the results of this study demonstrate the centrality of knowledge and

    Hagelstein, Karen

    2009-09-01

    The "cradle to grave" concept of managing chemicals and wastes has been a descriptive analogy of proper environmental stewardship since the 1970s. The concept incorporates environmentally sustainable product choices-such as metal alloys utilized steel products which civilization is dependent upon. Manganese consumption is related to the increasing production of raw steel and upgrading ferroalloys. Nonferrous applications of manganese include production of dry-cell batteries, plant fertilizer components, animal feed and colorant for bricks. The manganese ore (high grade 35% manganese) production world wide is about 6 million ton/year and electrolytic manganese metal demand is about 0.7 million ton/year. The total manganese demand is consumed globally by industries including construction (23%), machinery (14%), and transportation (11%). Manganese is recycled within scrap of iron and steel, a small amount is recycled within aluminum used beverage cans. Recycling rate is 37% and efficiency is estimated as 53% [Roskill Metals and Minerals Reports, January 13, 2005. Manganese Report: rapid rise in output caused by Chinese crude steel production. Available from: http://www.roskill.com/reports/manganese.]. Environmentally sustainable management choices include identifying raw material chemistry, utilizing clean production processes, minimizing waste generation, recycling materials, controlling occupational exposures, and collecting representative environmental data. This paper will discuss two electrolytically produced manganese metals, the metal production differences, and environmental impacts cited to date. The two electrolytic manganese processes differ due to the addition of sulfur dioxide or selenium dioxide. Adverse environmental impacts due to use of selenium dioxide methodology include increased water consumption and order of magnitude greater solid waste generation per ton of metal processed. The use of high grade manganese ores in the electrolytic process also

  12. Sustainable Product Indexing: Navigating the Challenge of Ecolabeling

    Directory of Open Access Journals (Sweden)

    Jay S. Golden

    2010-09-01

    Full Text Available There is growing scientific evidence that improving the sustainability of consumer products can lead to significant gains in global sustainability. Historically, environmental policy has been managed by bureaucracies and institutions in a mechanistic manner; this had led to many early successes. However, we believe that if policy concerning product sustainability is also managed in this way, negative unintended consequences are likely to occur. Thus, we propose a social-ecological systems approach to policy making concerning product sustainability that will lead to more rapid and meaningful progress toward improving the environmental and social impacts of consumer products.

  14. Learning challenges and sustainable development: A methodological perspective.

    Seppänen, Laura

    2017-01-01

    Sustainable development requires learning, but the contents of learning are often complex and ambiguous. This requires new integrated approaches from research. It is argued that investigation of people's learning challenges in every-day work is beneficial for research on sustainable development. The aim of the paper is to describe a research method for examining learning challenges in promoting sustainable development. This method is illustrated with a case example from organic vegetable farming in Finland. The method, based on Activity Theory, combines historical analysis with qualitative analysis of need expressions in discourse data. The method linking local and subjective need expressions with general historical analysis is a promising way to overcome the gap between the individual and society, so much needed in research for sustainable development. Dialectically informed historical frameworks have practical value as tools in collaborative negotiations and participatory designs for sustainable development. The simultaneous use of systemic and subjective perspectives allows researchers to manage the complexity of practical work activities and to avoid too simplistic presumptions about sustainable development.

    2013-10-01

    Innovative curriculum designs are vital for effective learning in contemporary nursing education where traditional modes of delivery are not adequate to meet the learning needs of postgraduate students. This instance of postgraduate teaching in a distributed learning environment offered the opportunity to design a flexible learning model for teaching advanced clinical skills. To present a sustainable model for flexible learning that enables specialist nurses to gain postgraduate qualifications without on-campus class attendance by teaching and assessing clinical health care skills in an authentic workplace setting. An action research methodology was used to gather evidence and report on the process of curriculum development of a core unit, Comprehensive Health Assessment (CHA), within 13 different postgraduate speciality courses. Qualitative data was collected from 27 teaching academics, 21 clinical specialist staff, and 7 hospital managers via interviews, focus groups and journal reflections. Evaluations from the initial iteration of CHA from 36 students were obtained. Data was analyzed to develop and evaluate the curriculum design of CHA. The key factors indicated by participants in the curriculum design process were coordination and structuring of teaching and assessment; integration of content development; working with technologies, balancing specialities and core knowledge; and managing induction and expectations. A set of recommendations emerged as a result of the action research process. These included: a constructive alignment approach to curriculum design; the production of a facilitator's guide that specifies expectations and unit information for academic and clinical education staff; an agreed template for content authors; and the inclusion of synchronous communication for real-time online tutoring. The highlight of the project was that it built curriculum design capabilities of clinicians and students which can sustain this alternative model of online

  3. Improving Software Sustainability: Lessons Learned from Profiles in Science.

    2013-01-01

    The Profiles in Science® digital library features digitized surrogates of historical items selected from the archival collections of the U.S. National Library of Medicine as well as collaborating institutions. In addition, it contains a database of descriptive, technical and administrative metadata. It also contains various software components that allow creation of the metadata, management of the digital items, and access to the items and metadata through the Profiles in Science Web site [1]. The choices made building the digital library were designed to maximize the sustainability and long-term survival of all of the components of the digital library [2]. For example, selecting standard and open digital file formats rather than proprietary formats increases the sustainability of the digital files [3]. Correspondingly, using non-proprietary software may improve the sustainability of the software--either through in-house expertise or through the open source community. Limiting our digital library software exclusively to open source software or to software developed in-house has not been feasible. For example, we have used proprietary operating systems, scanning software, a search engine, and office productivity software. We did this when either lack of essential capabilities or the cost-benefit trade-off favored using proprietary software. We also did so knowing that in the future we would need to replace or upgrade some of our proprietary software, analogous to migrating from an obsolete digital file format to a new format as the technological landscape changes. Since our digital library's start in 1998, all of its software has been upgraded or replaced, but the digitized items have not yet required migration to other formats. Technological changes that compelled us to replace proprietary software included the cost of product licensing, product support, incompatibility with other software, prohibited use due to evolving security policies, and product abandonment

It was carried out an investigation in the central region of Cuba, in the period of the 2002-2009, with the purpose of promoting the environmental education in the tobacco sector, by means of the training and the agricultural extension, to contribute to obtain the sustainable productions. Theoretical and empiric methods were used, with them a diagnosis of the learning necessities was obtained on the topic and a program of pertinent training was applied through the agricultural extension. The obtained results indicated advances in the environmental education that were evidenced in the academic preparation of the professionals, the participation in events and development of projects referred to the environmental topic. Also the technical attendance to producers, the introduction and extension of scientific achievements, they propitiated the application of agroecological practices in the tobacco production with the purpose of obtaining high yield and quality with less noxious effects to the environment.

    Full Text Available Tao is the source of ten thousand things ... The ten thousand things carry yin and embrace yang. They achieve harmony by combining these forces ... The ten thousand things are born of being. Being is born of not being. (From verses 40, 42 and 62 Many scholars have observed that realisation of the concept of sustainability, as a process of human interaction with the natural world, will require a paradigmatic change in world view (Lee et al, 2000; Van der Ryn, 1996. This need for change is particularly true in so-called Western thought, which, historically, has had a mechanistic view of the interrelationships between people and their world, whether cultural or natural. This view has contributed to a problem-solving, expediency-based, and short-term- gain perspective that makes sustainability, in the holistic sense, impossible in the modern world. This paper examines an alternative philosophic system that can be used to look beyond traditional European/modern approaches and to allow the achievement of real sustainability. The Chinese philosophy of Daoism (Taoism and the three principal areas in which it can be used to reframe contemporary perceptions of the natural and cultural world is the approach discussed here. Specifically, I discuss Daoism as a philosophy, as literature and as artistic inspiration, all in the context of environmental sustainability. Daoism emerged out of traditional Chinese animistic beliefs and geomantic practices about 2,300 years ago, when the teachings of one Laotzi (Lao-tzu were recorded as the Daodejing (Tao Te Ching, or, as sometimes translated into English, The Way and Its Power (Clarke, 2000; Fenton et al, 1983; Palmer, 1991. Daoism, in its ritualistic, religious form, first became widely known in Euro-American thought in the nineteenth century. When, in the 1960s, numerous translations of the Daodejing and other Daoist texts became popularised by writers such as Alan Watts, the more direct philosophical

    The social and political pressure to change egg production from conventional cage systems to alternative systems has been largely driven by the desire to provide more behavioral freedom for egg-laying hens. However, a change of this magnitude can affect other components of the production system and may result in unintended outcomes. To understand this issue, a Socially Sustainable Egg Production project was formed to 1) conduct a holistic and integrated systematic review of the current state of knowledge about various aspects of sustainable egg production, and 2) develop a coordinated grant proposal for future extramural funding based on the research priorities identified from the review. Expert study groups were formed to write evidence-based papers in 5 critical sustainability areas: hen health and welfare, economics, food safety and quality, public attitudes, and environmental impacts. These papers were presented as the PSA Emerging Issues Symposium on Social Sustainability of Egg Production at the 2010 Poultry Science Association meeting.

    Setting directions and goals for animal production systems requires the integration of information achieved through internal and external processes. The importance of stakeholder input in setting goals for sustainable animal production systems should not be overlooked by the agricultural animal industries. Stakeholders play an integral role in setting the course for many aspects of animal production, from influencing consumer preferences to setting public policy. The Socially Sustainable Egg Production Project (SSEP) involved the development of white papers on various aspects of egg production, followed by a stakeholder workshop to help frame the issues for the future of sustainable egg production. Representatives from the environmental, food safety, food retail, consumer, animal welfare, and the general farm and egg production sectors participated with members of the SSEP coordination team in a 1.5-d workshop to explore socially sustainable egg production. This paper reviews the published literature on values integration methodologies and the lessons learned from animal welfare assessment models. The integration method used for the SSEP stakeholder workshop and its outcome are then summarized. The method used for the SSEP stakeholder workshop can be used to obtain stakeholder input on sustainable production in other farm animal industries.

    2013-12-01

    Full Text Available Education conceptualised in terms of the broader project of socially sustainable development (SSD makes cooperative learning (CL valuable in realising the former. Cooperative learning emphasises cooperation as integral to learner success, and because of this CL strategies have been found to be successful in fostering positive intergroup attitudes in classrooms, multicultural and otherwise. Social sustainable development concerns those aspects of human life and human relations which are necessary for the survival of society. Apart from it being particularly instrumental in improving learners’ academic performance, CL is equally valuable in promoting positive social relations amongst group members. Such relations are important for achieving social sustainable development. Therefore, CL could particularly be valuable to develop in learners, and the broader society, the social dispositions required for a socially sustainable South African society. My argument centres on the potential of CL as a practical strategy towards the development of a social sustainable South African society. In an attempt to demonstrate that CL holds the potential to contribute towards a social sustainable South African society, I’ll be focusing on the core tenets of SSD. These tenets are explored in relation to the principles and social outcomes of CL in order to establish the extent the latter could be instrumental in promoting SSD.

    Full Text Available The debate on local ownership in peacebuilding policies is relatively recent, inherited from the reflection on aid efficiency and sustainability. When focusing on its application at the field level, like in the Haitian case, it becomes evident that its inclusion in the peacebuilding doctrine of all major donors has not had a correspondence at the strategic and operative levels. This article is the result of a research in the field on how the concept of “local ownership” in peacebuilding efforts is put into practice and perceived by different stakeholders. The authors focused on the on-going Justice reform in Haiti before the Earthquake of January 2010 to better understand the dynamics between international and local actors, from the policy definition stage to their application at the country level.

    SUMMARY Activation of the ventral tegmental area (VTA) and mesolimbic networks is essential to motivation, performance, and learning. Humans routinely attempt to motivate themselves, with unclear efficacy or impact on VTA networks. Using fMRI, we found untrained participants’ motivational strategies failed to consistently activate VTA. After real-time VTA neurofeedback training, however, participants volitionally induced VTA activation without external aids, relative to baseline, Pre-Test, and control groups. VTA self-activation was accompanied by increased mesolimbic network connectivity. Among two comparison groups (no neurofeedback, false neurofeedback) and an alternate neurofeedback group (nucleus accumbens), none sustained activation in target regions of interest nor increased VTA functional connectivity. The results comprise two novel demonstrations: learning and generalization after VTA neurofeedback training and the ability to sustain VTA activation without external reward or reward cues. These findings suggest theoretical alignment of ideas about motivation and midbrain physiology and the potential for generalizable interventions to improve performance and learning. PMID:26948894

  13. Sustained Professional Development on Cooperative Learning: Impact on Six Teachers' Practices and Students' Learning.

    Science.gov (United States)

    Goodyear, Victoria A

    2017-03-01

    It has been argued, extensively and internationally, that sustained school-based continuous professional development (CPD) has the potential to overcome some of the shortcomings of traditional one-off CPD programs. Yet, the evidence base on more effective or less effective forms of CPD is contradictory. The mechanisms by which sustained support should be offered are unclear, and the impacts on teachers' and students' learning are complex and difficult to track. The purpose of this study was to examine the impact of a sustained school-based, tailored, and supported CPD program on teachers' practices and students' learning. Data are reported from 6 case studies of individual teachers engaged in a yearlong CPD program focused on cooperative learning. The CPD program involved participatory action research and frequent interaction/support from a boundary spanner (researcher/facilitator). Data were gathered from 29 video-recorded lessons, 108 interviews, and 35 field journal entries. (a) Individualized (external) support, (b) departmental (internal) support, and (c) sustained support impacted teachers' practices of cooperative learning. The teachers adapted their practices of cooperative learning in response to their students' learning needs. Teachers began to develop a level of pedagogical fluency, and in doing so, teachers advanced students' learning. Because this study demonstrates impact, it contributes to international literature on effective CPD. The key contribution is the detailed evidence about how and why CPD supported 6 individual teachers to learn-differently-and the complexity of the learning support required to engage in ongoing curriculum development to positively impact student learning.

  4. Yeasts in sustainable bioethanol production: A review

    Directory of Open Access Journals (Sweden)

    Siti Hajar Mohd Azhar

    2017-07-01

    Full Text Available Bioethanol has been identified as the mostly used biofuel worldwide since it significantly contributes to the reduction of crude oil consumption and environmental pollution. It can be produced from various types of feedstocks such as sucrose, starch, lignocellulosic and algal biomass through fermentation process by microorganisms. Compared to other types of microoganisms, yeasts especially Saccharomyces cerevisiae is the common microbes employed in ethanol production due to its high ethanol productivity, high ethanol tolerance and ability of fermenting wide range of sugars. However, there are some challenges in yeast fermentation which inhibit ethanol production such as high temperature, high ethanol concentration and the ability to ferment pentose sugars. Various types of yeast strains have been used in fermentation for ethanol production including hybrid, recombinant and wild-type yeasts. Yeasts can directly ferment simple sugars into ethanol while other type of feedstocks must be converted to fermentable sugars before it can be fermented to ethanol. The common processes involves in ethanol production are pretreatment, hydrolysis and fermentation. Production of bioethanol during fermentation depends on several factors such as temperature, sugar concentration, pH, fermentation time, agitation rate, and inoculum size. The efficiency and productivity of ethanol can be enhanced by immobilizing the yeast cells. This review highlights the different types of yeast strains, fermentation process, factors affecting bioethanol production and immobilization of yeasts for better bioethanol production.

    Considerable attention is now being given to the role and importance of education and learning implications of participatory resource and environmental governance. The contention is that such learning has the potential to transform behaviour, and in the case of resource management, may help change current patterns in resource use towards a more sustainable social-ecological system. Our purpose is to establish the opportunities for learning afforded to those participating in local level resource management committees in two Cambodian fishing communities and consider the learning outcomes from such opportunities. Our approach was qualitative and used a case study design. The findings establish a wide range of committee resource management activities that resulted in both instrumental (e.g., learning about administrative procedures) and communicative (e.g., insights into the need to conserve mangroves) learning. It was revealed that such learning can lead to changes in behaviour at the community level (e.g., managing local waste). Our findings also indicated a number of motivators and enablers of learning such as opportunities for dialogue, leadership and the presence of declining resources.

    Housing systems for laying hens have changed over the years due to increased public concern regarding animal welfare. In terms of sustainability, animal welfare is just one aspect that needs to be considered. Social aspects as well as environmental and economic factors need to be included as well. In this study, we assessed the sustainability of enriched cage, barn, free-range, and organic egg production systems following a predefined protocol. Indicators were selected within the social, environmental, and economic dimensions, after which parameter values and sustainability limits were set for the core indicators in order to quantify sustainability. Uncertainty in the parameter values as well as assigned weights and compensabilities of the indicators influenced the outcome of the sustainability assessment. Using equal weights for the indicators showed that, for the Dutch situation, enriched cage egg production was most sustainable, having the highest score on the environmental dimension, whereas free-range egg production gave the highest score in the social dimension (covering food safety, animal welfare, and human welfare). In the economic dimension both enriched cage egg and organic egg production had the highest sustainability score. When weights were attributed according to stakeholder outputs, individual differences were seen, but the overall scores were comparable to the sustainability scores based on equal weights. The provided method enabled a quantification of sustainability using input from stakeholders to include societal preferences in the overall assessment. Allowing for different weights and compensabilities helps policymakers in communicating with stakeholders involved and provides a weighted decision regarding future housing systems for laying hens. © 2015 Poultry Science Association Inc.

However, recent studies have found DA response sustained towards predictable reward in tasks involving self-paced behavior, and suggested that this response represents a motivational signal. We have previously shown that RPE can sustain if there is decay/forgetting of learned-values, which can be implemented as decay of synaptic strengths storing learned-values. This account, however, did not explain the suggested link between tonic/sustained DA and motivation. In the present work, we explored the motivational effects of the value-decay in self-paced approach behavior, modeled as a series of 'Go' or 'No-Go' selections towards a goal. Through simulations, we found that the value-decay can enhance motivation, specifically, facilitate fast goal-reaching, albeit counterintuitively. Mathematical analyses revealed that underlying potential mechanisms are twofold: (1) decay-induced sustained RPE creates a gradient of 'Go' values towards a goal, and (2) value-contrasts between 'Go' and 'No-Go' are generated because while chosen values are continually updated, unchosen values simply decay. Our model provides potential explanations for the key experimental findings that suggest DA's roles in motivation: (i) slowdown of behavior by post-training blockade of DA signaling, (ii) observations that DA blockade severely impairs effortful actions to obtain rewards while largely sparing seeking of easily obtainable rewards, and (iii) relationships between the reward amount, the level of motivation reflected in the speed of behavior, and the average level of DA. These results indicate that reinforcement learning with value-decay, or forgetting, provides a parsimonious mechanistic account for the DA's roles in value-learning and motivation. Our results also suggest that when biological systems for value-learning

    2016-05-01

    Full Text Available This case report is about a regional land-use planning project in the Netherlands. Initiated by the province of Gelderland and Radboud University (RU, the project aimed to create “Communities of Ownership” (CoO’s, local associations of townspeople who would engage in collaborative vision-building related to sustainable land development. The guiding conceptual model was “The Natural Step” (TNS, a systems-level approach to sustainability. We describe the land-use project and the learning history we constructed to help project managers and facilitators learn from the different perspectives that project actors conveyed. The learning history indicated that the project had limited success. We discuss four factors shaping the project’s results and the lessons learned related to those factors. The first lesson concerns the importance of a shared vision for sustainability among stakeholder groups. The second focuses on the preconditions necessary to work with The Natural Step effectively in certain contexts. Lesson three is about what it takes for a learning history to serve as a catalyst for collective learning and project improvement. Lesson four sheds light on the importance of respecting differences in stakeholders’ levels of sustainability awareness. We speculate that these differences may have shared characteristics with the kind of developmental differences that constructivist stage theorists of human development have articulated. Finally, we discuss the implications of our analysis for the leadership of sustainability initiatives.

    2013-09-01

    Food and nutrition security are intimately interconnected, since only a food based approach can help in overcoming malnutrition in an economically and socially sustainable manner. Food production provides the base for food security as it is a key determinant of food availability. This paper deals with different aspects of ensuring high productivity and production without associated ecological harm for ensuring adequate food availability. By mainstreaming ecological considerations in technology development and dissemination, we can enter an era of evergreen revolution and sustainable food and nutrition security. Public policy support is crucial for enabling this.

    Full Text Available Many garments made of leather, end up in landfills as waste following the end of its useful life. However, in the flow of production of a leather product, intense energy, chemicals, high volumes of water are consumed. This means that the carbon footprint and environmental loads are high. There are many research activities related to the recycling of textile products, and recycling chains, in this regard famous clothing brands have been organizing grand campaigns. In order to assess the case for leather products that have an important place in the ready-to-wear segment, one should ask the following questions: “How do the big companies and brands in this sector participate in the environmental movement? And importantly, what are the best attempts to recycle leather products? What can be done about the future of leather products recycling and innovative sustainable designs?” when considering sustainable design using recycled leather from end-of-life leather products. In this study, examples of innovative best practices, which were adopted by new brands for recycling and reuse of various types of waste, in order to perform a sustainable product design were presented with the attempt of clarifying aforementioned questions. These new initiatives and practices can develop a novel perspective for academicians and professionals engaged in the field of leather and fashion design, and the concept of sustainable design can be introduced to wider masses.

    Full Text Available The availability of and preference for eco-friendly products have increased; however, understanding of sustainable products is still insufficient because most studies have been focused only on organic products. The availability and understanding of organic products are high, but not complete. With regards to environmental protection, it is important to focus not only on the eco-friendly ingredients but also on the eco-friendly packaging because packaging has recently been found to be a primary cause of pollution. Through three studies, this article investigated the interaction between the effect of consumers’ willingness to buy (WTB, the price premium for eco-friendliness (internal: eco-friendly ingredients vs. external: eco-friendly packaging, and the product’s attributes. Three experimental studies were conducted to determine whether the consumers’ WTB and the price premium for sustainable products differ according to the eco-friendliness of the product and the product’s attributes. In Study 1 and Study 3, analysis of variance (ANOVA was conducted; and, in Study 2, analysis of covariance (ANCOVA was conducted. The results of Study 1 and Study 2 suggested that the consumers’ WTB for sustainable products can differ according to the product’s attribute. Moreover, results of Study 3 revealed that consumers’ WTB and satisfaction for sustainable products can differ according to level of packaging.

  11. How to Deliver Open Sustainable Innovation: An Integrated Approach for a Sustainable Marketable Product

    Directory of Open Access Journals (Sweden)

    Francesco Cappa

    2016-12-01

    Full Text Available The adoption of open innovation and peer production, powered by 3D printing technology, is transforming traditional manufacturing methods towards a “third industrial revolution”. The purpose of this research is to provide empirical evidence for an integrated approach, based on collaborative product development and peer production, combined with 3D printing, to deliver more sustainable, yet competitive, marketable products. In particular, this experimental study is conducted in the context of mobile forensics, an emerging market where limited expensive products exist and alternative solutions are needed. The technical viability and economic feasibility of the prototype developed in this research validate the proposed integrated approach, which could be a game-changer in the field of mobile forensics, as well as in other sectors. The sustainability improvements with this approach are a reduction of the total cost, thereby making it affordable for lower income users, and a decrease in energy consumption and pollutant emissions. The validated integrated approach offers start-up opportunities to develop and deliver more sustainable, marketable products, towards the paradigm of Open Sustainable Innovation. While the device developed and tested in this research has similar features to existing products, the methodology, implementation, and motivation are original.

  15. Not Deep Learning but Autonomous Learning of Open Innovation for Sustainable Artificial Intelligence

    Directory of Open Access Journals (Sweden)

    JinHyo Joseph Yun

    2016-08-01

    Full Text Available What do we need for sustainable artificial intelligence that is not harmful but beneficial human life? This paper builds up the interaction model between direct and autonomous learning from the human’s cognitive learning process and firms’ open innovation process. It conceptually establishes a direct and autonomous learning interaction model. The key factor of this model is that the process to respond to entries from external environments through interactions between autonomous learning and direct learning as well as to rearrange internal knowledge is incessant. When autonomous learning happens, the units of knowledge determinations that arise from indirect learning are separated. They induce not only broad autonomous learning made through the horizontal combinations that surpass the combinations that occurred in direct learning but also in-depth autonomous learning made through vertical combinations that appear so that new knowledge is added. The core of the interaction model between direct and autonomous learning is the variability of the boundary between proven knowledge and hypothetical knowledge, limitations in knowledge accumulation, as well as complementarity and conflict between direct and autonomous learning. Therefore, these should be considered when introducing the interaction model between direct and autonomous learning into navigations, cleaning robots, search engines, etc. In addition, we should consider the relationship between direct learning and autonomous learning when building up open innovation strategies and policies.

  16. Sustainable Algae Biodiesel Production in Cold Climates

    2010-01-01

    Full Text Available This life cycle assessment aims to determine the most suitable operating conditions for algae biodiesel production in cold climates to minimize energy consumption and environmental impacts. Two hypothetical photobioreactor algae production and biodiesel plants located in Upstate New York (USA are modeled. The photobioreactor is assumed to be housed within a greenhouse that is located adjacent to a fossil fuel or biomass power plant that can supply waste heat and flue gas containing CO2 as a primary source of carbon. Model results show that the biodiesel areal productivity is high (19 to 25 L of BD/m2/yr. The total life cycle energy consumption was between 15 and 23 MJ/L of algae BD and 20 MJ/L of soy BD. Energy consumption and air emissions for algae biodiesel are substantially lower than soy biodiesel when waste heat was utilized. Algae's most substantial contribution is a significant decrease in the petroleum consumed to make the fuel.

    2015-07-01

    Full Text Available Speaking of mining and sustainability sounds contradictory, as the environmental impact generated by resource extraction is well known. However, there are mining companies that are working to be safe and environmentally friendly. An example of this is presented in this study aimed at identifying occupational risks generated by the activities of a small-scale gold and silver mine located in northwestern Mexico. The methodology followed was a Sustainable Production Program (SPP based on a continuous cycle of five steps in which the tools of cleaner production and pollution prevention are adapted. As a result of this project, it was possible to implement SPP activities: training for workers, use of personal protective equipment and adequate handling of chemicals. As a conclusion, it was verified that SPP application helped this mining company move towards sustainable patterns of production.

    2012-09-15

    In the present thesis it was aimed at achieving thermodynamic analysis of reactions involved in enzymatic biodiesel production with specific focus on chemical and phase equilibria of reactive systems. Lipase-catalyzed biodiesel production (biocatalytic ethanolysis) presents significant advantages: Easy recovery of glycerol, no complex down-processing operations for elimination of catalyst and salt, and requires less organic solvent and lower energy consumption compared with conventional chemical methods. In overall, the major aims of this thesis were evaluating and subsequently finding feasible solutions to the questions emerged during the corresponding studies that have been performed worldwide. Some of the questions that were answered as appropriate as possible can be listed as follows: 1) What is the solubility of EtOH in vegetable oils and in FAEE blends and how does it change with temperature? 2) Is it possible to prevent denaturing impact of EtOH on biocatalysts? 3) What are the feedstock content (water and FFA) impacts on glycerol and EtOH miscibility with ester species? 4) Is it necessary removing glycerol by-product simultaneously? 5) Is it feasible providing monophasic or homogeneous reaction media that procure lower external mass transfer resistance? 6) What are the moisture absorption limits of FAAE species? 7) How are the interactions of reactive species in terms of miscibility/immiscibility phenomena? 8) Is it thermodynamically feasible providing monophasic reaction media? 9) How can LLE and VLE phase behaviors help to determine optimum reaction conditions? 10) How can the results of LLE and VLE studies be used so as to determine appropriate refining operations?

    Overall, our results confirm that wild algal species sequester a wide range of organic and metal contaminants and excess nutrients (PAHs, trace metals, and nutrients) from natural waters, and suggest parameters that could be useful in predicting uptake rates for algae growing on an algal floway or other algal growth systems in the environment or in industrial processes. The implication for various fuel production processes differ with the detailed unit operations involved, and these results will be of use in the developing of scaling experiments for various types of engineering process designs.

  3. Improving the sustainability of global meat and milk production.

    Science.gov (United States)

    Salter, Andrew M

    2017-02-01

    Global demand for meat and dairy products has increased dramatically in recent decades and, through a combination of global population growth, increased lifespan and improved economic prosperity in the developing world will inevitably continue to increase. The predicted increases in livestock production will put a potentially unsustainable burden on global resources, including land for production of crops required for animal feed and fresh water. Furthermore, animal production itself is associated with greenhouse gas production, which may speed up global warming and thereby impact on our ability to produce food. There is, therefore, an urgent need to find methods to improve the sustainability of livestock production. This review will consider various options for improving the sustainability of livestock production with particular emphasis on finding ways to replace conventional crops as sources of animal feeds. Alternatives, such as currently underutilised crops (grown on a marginal land) and insects, reared on substrates not suitable for direct consumption by farm animals, represent possible solutions. Coupled with a moderation of excessive meat consumption in wealthier countries, such strategies may secure the long-term sustainability of meat and milk production and mitigate against the adverse health effects of excessive intake.

    Ignacio TRAVERSO RIBÓN

    2016-05-01

    Full Text Available In a project-based learning experience, the detailed monitoring of the activities in which team members participate can be useful to evaluate their work. Using learning-oriented assessment procedures, supervisors can assess the teamwork abilities with a formative purpose. Evaluation strategies such as self-assessment, peer assessment and co-assessment are often used to make evaluation formative and sustainable. Conducting an assessment strategy is not easy for team members, since they need before to have a reasonable understanding of the evaluation process and criteria. This paper describes a learning-oriented evaluation methodology and an open data framework that can be applied to collaborative project settings. An evaluation rubric and a series of indicators that provide evidences about the developed skills have been elaborated and applied in a small-scale project-based course. Projects were managed and developed with the help of an open source software forge that contains a ticketing tool for planning and tracking of tasks, a version control repository to save the software outcomes, and using a wiki to host text deliverables. The experience provides evidences in favor of using the assessment method and open data framework to make teamwork evaluation more sustainable.

    Changes that improve the quality of health care should be sustained. Falling back to old, unsatisfactory ways of working is a waste of resources and can in the worst case increase resistance to later initiatives to improve care. Quality improvement relies on changing the clinical system yet factors that influence the sustainability of quality improvements are poorly understood. Theoretical frameworks can guide further research on the sustainability of quality improvements. Theories of organizational learning have contributed to a better understanding of organizational change in other contexts. To identify factors contributing to sustainability of improvements, we use learning theory to explore a case that had displayed sustained improvement. Førde Hospital redesigned the pathway for elective surgery and achieved sustained reduction of cancellation rates. We used a qualitative case study design informed by theory to explore factors that contributed to sustain the improvements at Førde Hospital. The model Evidence in the Learning Organization describes how organizational learning contributes to change in healthcare institutions. This model constituted the framework for data collection and analysis. We interviewed a strategic sample of 20 employees. The in-depth interviews covered themes identified through our theoretical framework. Through a process of coding and condensing, we identified common themes that were interpreted in relation to our theoretical framework. Clinicians and leaders shared information about their everyday work and related this knowledge to how the entire clinical pathway could be improved. In this way they developed a revised and deeper understanding of their clinical system and its interdependencies. They became increasingly aware of how different elements needed to interact to enhance the performance and how their own efforts could contribute.

    2012-06-01

    Full Text Available The product development is a process that addresses sustainability issues inside companies. Many approaches have been discussed in academy concerning sustainability, as Natural Capitalism, Design for Environment (DfE and Life Cycle Analysis (LCA, but a question arises: which is indicated for what circumstance? This article aim is the proposition of a classification, based on a literature review, for 15 of these approaches. The criteria were: (i approach nature, (ii organization level, (iii integration level in Product Development Process (PDP, and (iv approach relevance for sustainability dimensions. Common terms allowed the establishment of connections among the approaches. As a result the researchers concluded that, despite they come from distinct knowledge areas they are not mutually excludent, on the contrary, the approaches may be used in a complementary way by managers. The combined use of complementary approaches is finally suggested in the paper.

    Accelerated mass loss from the Greenland ice sheet leads to glacier retreat and an increasing input of glacial meltwater to the fjords and coastal waters around Greenland. These high latitude ecosystems are highly productive and sustain important fisheries, yet it remains uncertain how they will respond to future changes in the Arctic cryosphere. Here we show that marine-terminating glaciers play a crucial role in sustaining high productivity of the fjord ecosystems. Hydrographic and biogeochemical data from two fjord systems adjacent to the Greenland ice sheet, suggest that marine ecosystem productivity is very differently regulated in fjords influenced by either land-terminating or marine-terminating glaciers. Rising subsurface meltwater plumes originating from marine-terminating glaciers entrain large volumes of ambient deep water to the surface. The resulting upwelling of nutrient-rich deep water sustains a high phytoplankton productivity throughout summer in the fjord with marine-terminating glaciers. In contrast, the fjord with only land-terminating glaciers lack this upwelling mechanism, and is characterized by lower productivity. Data on commercial halibut landings support that coastal regions influenced by large marine-terminating glaciers have substantially higher marine productivity. These results suggest that a switch from marine-terminating to land-terminating glaciers can substantially alter the productivity in the coastal zone around Greenland with potentially large ecological and socio-economic implications. © 2017 The Authors.

    2017-04-01

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

  6. Sustainability, Learning and Capability: Exploring Questions of Balance

    Directory of Open Access Journals (Sweden)

    William A. H. Scott

    2010-12-01

    Full Text Available It is argued that sustainable development makes best sense as a social learning process that brings tangible and useful outcomes in terms of understanding and skills, and also reinforces the motivation and capability for further learning. Thus, there are always balances to be struck between a broad-based, wide-ranging education and a more specialist one; between a focus on ideas themselves, and on their application in social or economic contexts; and between keeping ideas separate, and integrating them. This paper will explore the nature of such balances, and the issues to bear in mind when striking them, focusing on schools, university and college contexts within the United Kingdom.

  8. Permaculture in higher education: Teaching sustainability through action learning

    Science.gov (United States)

    Battisti, Bryce Thomas

    This is a case study of the use of Action Learning (AL) theory to teach and confer degrees in Permaculture and other forms of sustainability at the newly formed Gaia University International (GUI). In Chapter Two I argue that GUI, as an institution of higher learning, is organized to provide support for learning. The goal of the university structure is to provide students, called Associates, with a vehicle for accumulation of credit towards a bachelor's degree. This organizational structure is necessary, but insufficient for AL because Associates need more than an organization to provide and coordinate their degree programs. In other words, just because the network of university structures are organized in ways that make AL possible and convenient, it does not necessarily follow that Action Learning will occur for any individual Associate. The support structures within GUI's degrees are discussed in Chapter Three. To a greater or lesser degree GUI provides support for personal learning among Associates as advisors and advisees with the goal of helping Associates complete and document the outcomes of world-change projects. The support structures are necessary, but not sufficient for AL because the personal learning process occurring for each Associate requires transformative reflection. Additionally, because Associates' attrition rate is very high, many Associates do not remain enrolled in GUI long enough to benefit from the support structures. At the simplest organizational level I discuss the reflection process conducted in the patterned interactions of assigned learning groups called Guilds (Chapter Four). These groups of Associates work to provide each other with the best possible environment for personal learning through reflection. As its Associates experience transformative reflection, GUI is able to help elevate the quality of world-change efforts in the Permaculture community. Provided the organizational and support structures are in place, this reflection

    2011-02-01

    Full Text Available Sustainable development is a paradigm that has evolved over the time, since the ideas of socially acceptable and compatible development, on which it was originally based, are now supported by the more recent notions of ecological equilibria and production process economy, both of which need to be also preserved. Environmental and health safety, rational use of the natural resources and technological tools, upkeep of high social growth rates and respect of a social equity are the basis of the sustainability for any production process, including the agriculture. The new globalization framework has penalized small farms and, at the same time, has put serious constraints to the development of stronger economic systems (medium/large farms, as well. As consequence, the EU has outlined several strategic programs to support small agricultural systems in marginal areas by: 1 strengthening all the quality- related aspects of agricultural production, including nutritional and cultural traits associated to local, typical and in some cases to neglected crops; 2 improving traditional cultural practices by adapting the cropping cycles and fomenting new partnerships between the different parts of the production chain, as for example; promotion of small horticultural chains. Specific political actions for the horticultural production sector have also been developed. Some of these policies are specifically addressed to preserve the biodiversity and to create quality labels certifying typical and/or organic products. All of these are possible strategies that may counteract and cope with the globalization process and increase the competitiveness of many production systems especially those performed by local and small entrepreneurs. New sustainable development models are required by both the market and the implicit requirements of the production system, inside a context on which Europe must face with new emerging economies with lower production costs, by increasing

    2011-12-01

    Full Text Available Change is a constant condition within organizations, due to the introduction of new technologies, market place demands, external forces, and pressures to improve organizational effectiveness. However, large-scale organizational change efforts tend to fail more than 70 percent of the time. One of the recent large-scale movements within higher education institutions is towards accountability and assessment on student learning outcomes, which is higher education institutions should assess whether students learn what they should and retain the knowledge once learned. In addition, assessment findings should become a feedback mechanism to improve students’ education experiences. In this paper the author describe a change effort within a research university for compliance with regional accrediting commission requirements and program specific (engineering accreditation requirements and procedures in defining and implementing assessment of student learning outcomes. The main issue is not just introducing new contents to the member of the faculty, but making sure that the assessment effort is meaningful. Issues arrived and solutions in creating and sustaining the change effort will be discussed.

    2013-12-01

    Full Text Available The rapid evolution of civilisation within the last two hundred years has involved the replacement of extensive, pastoral livestock systems for intensive production methods. The dangers implicit in this rapid evolution are discussed by Forrester (1971,in the Meadows report (1972 and latterly the necessity for “sustainable development” was flagged by the Brudtland Report (1987. The last agrarian reform in Romania increased the weight of small farms and led to non sustainable agriculture. In such conditions we are obliged to follow a twin-track strategy: (1livestock systems with high productivity potentials; (2traditional pastoral systems and organic agriculture, on marginal lands, which allow the utilisation of extensive grazing lands, the conservation of environment, genetic resources, landscape, the minimisation of the use of non-renewable resources and the production of "natural foods".

  17. Indicators review for environmental aspects communication on sustainable products consumption

    Directory of Open Access Journals (Sweden)

    Gabriel Cereceda

    2015-03-01

    Full Text Available If we consider that the viability of any development goes through its economic feasibility and the whole economy is based on the consumption of goods, we could say that the economic viability of Sustainable Development goes through the consumption of sustainable products. Thus, as a society, we must change our behaviors and habits, but not the way we consume, because we could destabilize the current economic system. In this sense, the consumption of these goods depends on the ability to differentiate them from the traditional products and on how to communicate its environmental aspects. Historically, the instrument used for this purpose has been the Ecolabel, but this has not influenced the purchasing decisions and has caused confusion among consumers due to the type of indicators and how these are being used to communicate the environmental aspects of this kind of products. As a conclusion, the definition of mixed indicators; the generation of benchmarks from similar products; and the decrease of asymmetry of market information by the use of clear and credible information certified by a third party, seem to be the solution to the problem of communication for sustainable products consumption.

  18. Forage based animal production systems and sustainability, an invited keynote

    Directory of Open Access Journals (Sweden)

    Abdul Shakoor Chaudhry

    2008-07-01

    Full Text Available Forages are essential for the successful operation of animal production systems. This is more relevant to ruminants which are heavily dependant upon forages for their health and production in a cost-effective and sustainable manner. While forages are an economical source of nutrients for animal production, they also help conserve the soil integrity, water supply and air quality. Although the role of these forages for animal production could vary depending upon the regional preferences for the animal and forage species, climate and resources, their importance in the success of ruminant production is acknowledged. However with the increasing global human population and urbanisation, the sustainability of forage based animal production systems is sometimes questioned due to the interrelationship between animal production and the environment. It is therefore vital to examine the suitability of these systems for their place in the future to supply quality food which is safe for human consumption and available at a competitive price to the growing human population. Grassland and forage crops are recognised for their contribution to the environment, recreation and efficiency of meat and milk production,. To maintain sustainability, it is crucial that such farming systems remain profitable and environmentally friendly while producing nutritious foods of high economical value. Thus, it is pertinent to improve the nutritive value of grasses and other forage plants in order to enhance animal production to obtain quality food. It is also vital to develop new forages which are efficiently utilised and wasted less by involving efficient animals. A combination of forage legumes, fresh or conserved grasses, crop residues and other feeds could help develop an animal production system which is economically efficient, beneficial and viable. Also, it is crucial to use efficient animals, improved forage conservation methods, better manure handling, and minimum

    The United Nations declared 2016 as the International Year of Pulses (grain legumes) under the banner 'nutritious seeds for a sustainable future'. A second green revolution is required to ensure food and nutritional security in the face of global climate change. Grain legumes provide an unparalleled solution to this problem because of their inherent capacity for symbiotic atmospheric nitrogen fixation, which provides economically sustainable advantages for farming. In addition, a legume-rich diet has health benefits for humans and livestock alike. However, grain legumes form only a minor part of most current human diets, and legume crops are greatly under-used. Food security and soil fertility could be significantly improved by greater grain legume usage and increased improvement of a range of grain legumes. The current lack of coordinated focus on grain legumes has compromised human health, nutritional security and sustainable food production.

    De Deyn, G B

    2015-01-01

    Sustainable production of food, feed and fiberwarrants sustainable soil management and crop protection. The tools available to achieve this are both in the realm of the plants and of the soil, with a key role for plant-soil interactions. At the plant level we have vast knowledge of variation within plant species with respect to pests and diseases, based on which we can breed for resistance. However, given that systems evolve this resistance is bound to be temporarily, hence also other strategies are needed. Here I plea for an integrative approach for sustainable production using ecological principles. Ecology, the study of how organisms interact with their environment, teaches us that diversity promotes productivity and yield stability. These effects are thought to be governed through resource use complementarity and reduced build-up of pests and diseases both above- and belowground. In recent years especially the role of soil biotic interactions has revealed new insights in how plant diversity and productivity are related to soil biodiversity and the functions soil biota govern. In our grassland biodiversity studies we found that root feeders can promote plant diversity and succession without reducing plant community productivity, this illustrates the role of diversity to maintain productivity. Also diversity within species offers scope for sustainable production, for example through awareness of differences between plant genotypes in chemical defense compounds that can attract natural enemies of pests aboveground- and belowground thereby providing plant protection. Plant breeding can also benefit from using complementarity between plant species in the selection for new varieties, as our work demonstrated that when growing in species mixtures plant species adapt to each other over time such that their resource acquisition traits become more complementing. Finally, in a recent meta-analysis we show that earthworms can stimulate crop yield with on average 25%, but

  3. Sustainable rural learning ecologies- a prolegomenon traversing transcendence of discursive notions of sustainability, social justice, development and food sovereignty

    Directory of Open Access Journals (Sweden)

    Dipane Hlalele

    2013-12-01

    Full Text Available This paper contributes, through traversing contested notions of sustainability, social justice, development and food sovereignty, to discourses around creation of sustainable rural learning ecologies. There has always been at least in the realm of scientific discourse, an attempt to dissociate the natural or physical environment from the social and human environment. This trend did not only affect the two spheres of existence only. It is further imbued and spawned fragmented and pervasive terminology, practices and human thought. Drawing from the ‘creating sustainable rural learning ecologies’ research project that commenced in 2011, I challenge and contest the use of such discourses and argue for the transcendence of such. This would, in my opinion, create space for harmonious and fluid co-existence between nature and humanity, such that the contribution of learning practices exudes and expedites sustainability in rural ecologies.

    Full Text Available This article explores one dimension of green marketing programs: their potential application as a solution in achieving and maintaining the ecological sustainability on global market. We examine the necessity to develop and launch green products which can respond to environment degradation as a treatment against this phenomenon. This paper is structured in three sections: the first section is related to a clear delimitation and a better understanding of terms; the second one is an overview of the literature about ecological sustainability; the third section is the most relevant part of this paper because is trying to shape a framework of marketing programs for the development of green products, considering the decisions related to marketing mix elements. Even if green marketing programs make sense, current understanding of how managers can start to develop or transform their marketing efforts is far from comprehensive; therefore, this study is addressed to this knowledge gap.

    Grass crops are the most important sources of human nutrition, and their improvement is centrally important for meeting the challenges of sustainable agriculture, for feeding the world's population and for developing renewable supplies of fuel and industrial products. We describe the complete sequence of the compact genome of Brachypodium distachyon (Brachypodium) the first pooid grass to be sequenced. We demonstrate the many favorable characteristics of Brachypodium as an experimental system and show how it can be used to navigate the large and complex genomes of closely related grasses. The functional genomics and other experimental resources that are being developed will provide a key resource for improving food and forage crops, in particular wheat, barley and forage grasses, and for establishing new grass crops for sustainable energy production.

    Full Text Available Restoring hedgerows, or other field edge plantings, to provide habitat for bees and other beneficial insects on farms is needed to sustain global food production in intensive agricultural systems. To date, the creation of hedgerows and other restored habitat areas on California farms remains low, in part because of a lack of information and outreach that addresses the benefits of field edge habitat, and growers' concerns about its effect on crop production and wildlife intrusion. Field studies in the Sacramento Valley highlighted that hedgerows can enhance pest control and pollination in crops, resulting in a return on investment within 7 to 16 years, without negatively impacting food safety. To encourage hedgerow and other restoration practices that enhance farm sustainability, increased outreach, technical guidance, and continued policy support for conservation programs in agriculture are imperative.

    Full Text Available This paper investigates correlation between subsidies to invest in development projects, innovation, financial performance and sustainable growth. The focus of the study is on subsidies for co-financing purchases of new technological equipment aimed at promoting innovation and production of new products. Subsidies are distributed based on the prepared European Union (EU and national programs for the purposes of faster economic growth in accordance with the policies and guidelines of the EU. The paper employs a combination of enterprises’ accounting data, data on subsidies and unique in-depth data obtained through a survey at the enterprise level. The results revealed a positive impact of subsidies on financial indicators, and only limited effect on innovation. While analyzing sustainable growth, we have established that the enterprises that received subsidies had a higher growth of financial indicators.

    Full Text Available The ecolabel is one of the indicators that quantify sustainable consumption and production, and ultimately, sustainable development. Ecolabelling is only one type of environmental labelling, and refers specifically to the provision of information to consumers about the relative environmental quality of a product. Ecolabels are granted on request of various organizations, both public and private, and are recognized only locally or nationally, regionally or internationally. Often coexist at the same time and same place, several types of environmental labels. The acceptance of a particular ecolabel is optional, and is made usually based on reputation, trust and awareness about the label and the level to promote certain brands for better lifestyle and for use the eco, organic or green products. There are currently tracking worldwide by Ecolabel Index, which is the largest global directory of ecolabels, 449 ecolabels in 197 countries, and 25 industry sectors, from which 109 are for textile products. The number of EU Ecolabel greatly increased, so that in the period 2000- 2010, the increase was more than 20 times. At the end of 2012, 17176 products or services was awarded EU Ecolabel. Curently, certainly, the number is much higher. Today, in the Ecolabel Index appear registered in Romania 23 types of ecolabels. Also, Romania currently has awarded 586 licenses for Eu Ecolabel, from which two for textile products and two for footwear.

    This study examines the prospects for strong growth in the supply and demand for animal products worldwide, especially in developing countries, where 80% of the world's population lives. Based on scientific publications, statistics and field observations, it reviews greenhouse gas emission levels from livestock, the ability of ruminant livestock systems to sequester carbon and the capacity of the livestock industry to meet the challenge of sustainable development and to share its benefits while minimising impacts to climate change. Special attention is paid to the situation of the 800 million livestock farmers in the world living at the extreme end of poverty. The study underlines the importance of improving livestock productivity and the interdependence of the economic, environmental and social components of sustainable development. It highlights how, in the least developed countries and most lower-middle-income countries, the pressure exerted by animal diseases hampers efforts to improve livestock productivity. Poor livestock farmers have not sufficiently benefited from development policies and need support to adopt technological advances to meet the challenges of sustainable development and poverty reduction.

    2013-09-01

    With recent advances in metabolic engineering, it is now technically possible to produce a wide portfolio of existing petrochemical products from biomass feedstock. In recent years, a number of modeling approaches have been developed to support the engineering and decision-making processes associated with the development and implementation of a sustainable biochemical industry. The temporal and spatial scales of modeling approaches for sustainable chemical production vary greatly, ranging from metabolic models that aid the design of fermentative microbial strains to material and monetary flow models that explore the ecological impacts of all economic activities. Research efforts that attempt to connect the models at different scales have been limited. Here, we review a number of existing modeling approaches and their applications at the scales of metabolism, bioreactor, overall process, chemical industry, economy, and ecosystem. In addition, we propose a multi-scale approach for integrating the existing models into a cohesive framework. The major benefit of this proposed framework is that the design and decision-making at each scale can be informed, guided, and constrained by simulations and predictions at every other scale. In addition, the development of this multi-scale framework would promote cohesive collaborations across multiple traditionally disconnected modeling disciplines to achieve sustainable chemical production.

    2014-03-01

    The Alabama Comprehensive Cancer Control Coalition (ACCCC) has developed an integrated and coordinated approach to reducing cancer incidence, morbidity, and mortality, and to improving the quality of life for cancer survivors, their families, and their caregivers. The ACCCC is currently in a maintenance phase and a formal plan for sustainability of the coalition was needed to keep the members engaged and productive. A training session in coalition sustainability conducted in 2013 identified the following elements as essential to success: (1) increased marketing of the coalition by simplifying its mission; (2) improved networking including flexibility in coalition meeting location and attendance; (3) increased membership satisfaction through transformational leadership; (4) revision of the working structure of committees and improved accountability; and (5) enhancement of partner satisfaction with coalition activities designed to recruit and retain new partners. A self-administered membership satisfaction survey was given to assess coalition mission, meeting logistics, organization, capacity building, and coalition goals. Results indicated that the subcategories of communication, mission, and meeting logistics were rated satisfied to very satisfied on a five-point scale. Although the ACCCC had clearly written goals, improvement could be made in leadership participation and new member orientation could be improved. Most members rated their parent organization as highly involved with the ACCCC and many offered suggestions on capacity building. Results of the sustainability training have clarified the ACCCC's plans to ensure coalition viability and improve strategies to inform stakeholders of the benefits of participation in the coalition.

    2017-03-01

    Climate change, soil degradation, and depletion of natural resources are becoming the most prominent challenges for crop productivity and environmental sustainability in modern agriculture. In the scenario of conventional farming system, limited chances are available to cope with these issues. Relay cropping is a method of multiple cropping where one crop is seeded into standing second crop well before harvesting of second crop. Relay cropping may solve a number of conflicts such as inefficient use of available resources, controversies in sowing time, fertilizer application, and soil degradation. Relay cropping is a complex suite of different resource-efficient technologies, which possesses the capability to improve soil quality, to increase net return, to increase land equivalent ratio, and to control the weeds and pest infestation. The current review emphasized relay cropping as a tool for crop diversification and environmental sustainability with special focus on soil. Briefly, benefits, constraints, and opportunities of relay cropping keeping the goals of higher crop productivity and sustainability have also been discussed in this review. The research and knowledge gap in relay cropping was also highlighted in order to guide the further studies in future.

  20. Water footprints of cities - indicators for sustainable consumption and production

    Hoff, H.; Döll, P.; Fader, M.; Gerten, D.; Hauser, S.; Siebert, S.

    2014-01-01

    Water footprints have been proposed as sustainability indicators, relating the consumption of goods like food to the amount of water necessary for their production and the impacts of that water use in the source regions. We further developed the existing water footprint methodology, by globally resolving virtual water flows from production to consumption regions for major food crops at 5 arcmin spatial resolution. We distinguished domestic and international flows, and assessed local impacts of export production. Applying this method to three exemplary cities, Berlin, Delhi and Lagos, we find major differences in amounts, composition, and origin of green and blue virtual water imports, due to differences in diets, trade integration and crop water productivities in the source regions. While almost all of Delhi's and Lagos' virtual water imports are of domestic origin, Berlin on average imports from more than 4000 km distance, in particular soy (livestock feed), coffee and cocoa. While 42% of Delhi's virtual water imports are blue water based, the fractions for Berlin and Lagos are 2 and 0.5%, respectively, roughly equal to the water volumes abstracted in these two cities for domestic water use. Some of the external source regions of Berlin's virtual water imports appear to be critically water scarce and/or food insecure. However, for deriving recommendations on sustainable consumption and trade, further analysis of context-specific costs and benefits associated with export production will be required.

    2015-07-01

    Full Text Available This paper considers the impact of audio-visual resources in enabling students to develop an understanding of the social aspects of sustainable product design. Building on literature con­cern­ing the learning preferences of ‘Net Generation’ learners, three audio-visual workshops were developed to introduce students to the wider social aspects of sustainability and encour­age students to reflect upon the impact of their practice. The workshops were delivered in five universities in Britain and Ireland among undergraduate and postgraduate students. They were designed to encourage students to reflect upon carefully designed audio-visual materials in a group-based environment, seeking to foster the preferences of Net Generation learners through collaborative learning and learning through discovery. It also sought to address the perceived weaknesses of this generation of learners by encouraging critical reflection. The workshops proved to be popular with students and were successful in enabling them to grasp the complexity of the social aspects of sustainable design in a short span of time, as well as in encouraging personal responses and creative problem solving through an exploration of design thinking solutions.

    We propose a structural model to study the effect of online product reviews on consumer purchases of experiential products. Such purchases are characterized by limited repeat purchase behavior of the same product item (such as a book title) but significant past usage experience with other products of the same type (such as books of the same genre). To cope with the uncertainty in quality of the product item, we posit that consumers may learn from their experience with the same type of product...

    2010-01-01

    Full Text Available The exhaustion of natural resources is a central problem in the international agenda. The particular case of Amazon forest is at the top on the international environmental debate. Two related problems are keys to be considered in the discussion of sustainable development in this region. First the predatory use of the natural resources of the forest mainly timber and genetic resources. Second the recognition of the existence of a population of around 20 million inhabitants in the region defined as “Legal Amazon Area”, aiming the improvement on the living conditions, enhancement of income level and acceleration of development. How to match both objectives is a puzzle faced by the present generation.The region is populated by initiatives of international non-governmental-organizations, most of them carrying good intentions but lacking the necessary knowledge on local formal and informal institutions to find ways to reach sustainable development. The result is the accelerated process of natural resources depletion, and social disorganization. The case of the production of Brazilian Nuts stands as a corollary of the lack of an institutional structure of property rights that does not provide incentives for sustainable development. The opposite effect is being observed as a result of the fragility of observable institutional arrangements.The case provides the counterfactual for the analysis of Ostrom (1990; 2008, where she presents virtuous cases of sustainable exploration of natural resources, mostly based on informal but solid institutions.

  4. Sustainability of organic food production: challenges and innovations.

    2015-02-01

    The greatest challenge for agriculture is to reduce the trade-offs between productivity and long-term sustainability. Therefore, it is interesting to analyse organic agriculture which is a given set of farm practices that emphasise ecological sustainability. Organic agriculture can be characterised as being less driven by off-farm inputs and being better embedded in ecosystem functions. The literature on public goods and non-commodity outputs of organic farms is overwhelming. Most publications address the positive effects of organic farming on soil fertility, biodiversity maintenance and protection of the natural resources of soil, water and air. As a consequence of focusing on public goods, organic agriculture is less productive. Meta-analyses show that organic agriculture yields range between 0·75 and 0·8 of conventional agriculture. Best practice examples from disadvantaged sites and climate conditions show equal or, in the case of subsistence farming in Sub-Saharan Africa, higher productivity of organic agriculture. Hence, organic agriculture is likely to be a good model for productive and sustainable food production. Underfunding in R&D addressing specific bottlenecks of organic agriculture are the main cause for both crop and livestock yield gaps. Therefore, the potential for improving the performance of organic agriculture through agricultural research is huge. Although organic farming is a niche in most countries, it is at the verge of becoming mainstream in leading European countries. Consumer demand has grown over the past two decades and does not seem to be a limiting factor for the future development of organic agriculture.

    2003-11-01

    The present study concentrates mainly on the estimation of land availability for biomass production and the estimation of sustainable biomass production potential for energy. The feasible surplus land area available for bioenergy plantation is estimated assuming two land availability scenarios (Scenarios 1 and 2) and three biomass demand scenarios (IBD Scenario, SBD Scenario and FBD Scenario). Scenario 1 assumes that 100% of the surplus area available in base year 1997 will be suitable for plantation without considering population growth and food production and that 75% of this surplus land is feasible for plantation. Scenario 2 assumes that future food requirement will grow by 20% and the potential surplus area will be reduced by that amount. The incremental biomass demand scenario (IBD Scenario) assumes that only the incremental demand for biomass in the year 2010 with respect to the base year 1997 has to be produced from new plantation. The sustainable biomass demand scenario (SBD Scenario) assumes that the total sustainable supply of biomass in 1997 is deducted from the future biomass demand in 2010 and only the balance is to be met by new plantation. The full biomass demand scenario (FBD Scenario) assumes that the entire projected biomass demand of the year 2010 needs to be produced from new plantation. The total feasible land area for the scenarios IBD-l, IBD-2, SBD-l, SBD-2, FBD-l and FBD-2 are approximately 0.96, 0.66, 0.80, 0.94, 0.60 and 0.30 Mha, respectively. Biomass production potential is estimated by selecting appropriate plant species, plantation spacing and productivity level. The results show that the total annual biomass production in the country could vary from 2 to 9.9 Mt. With the production option (i.e. 1.5 m x 1.5 m spacing plantation with fertilizer application) giving the highest yield, the total biomass production for energy under IBD Scenario would be 9.9 Mtyr{sup -l} for Scenario 1 and 6.7 Mtyr{sup -l} for Scenario 2. Under SBD Scenario

  6. Agroecology and the Sustainable Production of Food and ...

    Science.gov (United States)

    The silvopastoral, agricultural system of the montado in Southern Portugal is an example of the self-organization of an agroecological system adapted to the climate and soil conditions of the Mediterranean basin. This system with its consistent production of food, fiber, and ecosystem services along with its concomitant rural social organization has been sustained in the region for over 1000 years. However, the system has been gradually decreasing in extent since the 19th century and its rate of decline has accelerated since the 1980s. The causes of this decline have been traced in descending order of importance to land managment choices, spatial factors and environmental factors. In addition, past studies have shown that there is an optimum livestock support capacity for maintaining the health of the montado agroecosystem. In this study, we used the results of an emergy evaluation of a cattle farm as part of a montado agroecosystem to examine the effects of the European Union’s (EU) Common Agricultural Policy (CAP) on the viability of both cattle rearing and the long term regional sustainability of montado agroecosystems. We found that the CAP and its two pillars for providing subsidies, (1) Common Market Organization (CMO) and (2) Rural Development Policy (RDP) are complex and take into account many aspects of prices and markets for particular products, e.g., beef and veal (CMO) and sustainable rural development, e.g., silvopastoral agroecosystems (RDP).

    1998-12-31

    With this presentation the Norwegian Prime Minister opened the conference, the Offshore Northern Seas Conference, an important meeting place for the oil and gas industry. Today, sustainable development, the environment and human rights are vital issues that politicians and the petroleum industry have included on their agendas. The end of the 1980s and the beginning of the 1990s mark the beginning of a new era in terms of de regulated markets and a growing concern about the Earth`s capacity to sustain a growing population and the present production and consumption patterns. This shift in political and economic practices has promoted far-reaching institutional changes and a rapid spread of capital, information and skills and an unprecedented integration of the world economy. Energy demand over the next 25 years will depend on fossil fuels, but renewable energy will become increasingly more important. The environmental issues discussed are (1) the local impact of production, distribution and use of fossil fuels, (2) the limited availability of fossil fuels and (3) the impact of the emission of greenhouse gases. The Prime Minister then discusses issues of human rights in sustainable development

    2016-05-01

    Full Text Available An eco-village as defined by Robert Gilman is a “human-scale, full-featured settlement where you feel you know the others, and human activities are integrated with natural, biological systems.” Roland Mayerl argued that this maybe ideal, but there are huge challenges. He claims the challenges are at different levels—there is the physical layer that constitutes food production, animals, water and wastewater treatment. Other layers will be the built environment, the economic system and the governance in the village.This paper argues that one of the challenging layers is the human layer that was excluded in the modeling of many eco-village works. While there are many good models of an eco-village, sustainability will primarily be laid on the shoulders of the members of the community or the village for that matter. Sustainability should be espoused by the members of the eco-village. But how can sustainability be attained? What sustainability approach or strategy can be employed?“Communities of practice (COP are formed by people who engage in a process of collective learning in a shared domain of human endeavor.“ (Wenger, 2004 COPs are concepts commonly applied in organizations and virtual communities. Using this approach together with periphery participation and situated learning, this paper presents a human-based model of a sustainable eco-village and some useful examples.The paper also argues that an eco-village necessitates the support of technology in enhancing and preserving the shared practices. Hence, use of social media deployed in the web is one of the recommended ways that also permit collective action among members of the eco-village.

    The apparent incongruity between the increasing consumption of fuels and chemicals and the finite amount of resources has led us to seek means to maintain the sustainability of our society. Artificial photosynthesis, which utilizes sunlight to create high-value chemicals from abundant resources, is considered as the most promising and viable method. This Minireview describes the progress and challenges in the field of artificial photosynthesis in terms of its key components: developments in photoelectrochemical water splitting and recent progress in electrochemical CO2 reduction. Advances in catalysis, concerning the use of renewable hydrogen as a feedstock for major chemical production, are outlined to shed light on the ultimate role of artificial photosynthesis in achieving sustainable chemistry. © 2015 WILEY-VCH Verlag GmbH & Co.

    2015-12-01

    NOAA's Climate Data Record (CDR) Program was designed to be responsive to the needs of climate monitoring, research, and services with the ultimate aim of serving decision making across a spectrum of users for the long term. It requires the sustained production of high quality, multidecadal time series data describing the global atmosphere, oceans, and land surface that can be used for informed decision making. The challenges of a long-term program of sustaining CDRs, as contrasted with short-term efforts of traditional three-year research programs, are substantial and different. The sustained production of CDRs requires collaboration between experts in the climate community, data management, and software development and maintenance. It is also informed by scientific application and associated user feedback on the accessibility and usability of the produced CDRs. The CDR Program has developed a metric for assessing the maturity of CDRs with respect to data management, software, and user application and applied it to over 28 CDRs. The main/primary lesson learned over the past seven years is that a rigorous, team approach to data management, employing subject matter experts at every step, is critical to open and transparent production. This approach also makes it much easier to support the needs of users who want near-real-time production of "interim" CDRs for monitoring and users who want to use CDRs for tailored authoritative information, such as a drought index. This talk will review of the history of the CDR program, current status, and plans.

    2013-01-01

    Full Text Available The production of biofuels worldwide has been significant lately due to the shift from obtaining energy from nonrenewable energy (fossil fuels to renewable sources (biofuels. This energy shift arose as a result of the disturbing crude petroleum price fluctuations, uncertainties about fossil fuel reserves, and greenhouse gas (GHG concerns. With the production of biofuels increasing considerably and the current global biodiesel production from different feedstock, reaching about 6 billion liters per year, biodiesel production costs have been highly dependent on feedstock prices, ranging from 70 to 25; of total production costs, and in comparison with the conventional diesel fuel, the biodiesel is currently noncompetitive. An efficient production process is, therefore, crucial to lowering biodiesel production costs. The question of sustainability, however, arises, taking into account the African diverse conditions and how vital concerns need to be addressed. The major concern about biodiesel production costs can be reduced by finding value-added applications for its glycerol byproduct. This paper, thus, provides an overview of current research trends that could overcome the major hurdles towards profitable commercialization of biodiesel and also proposes areas of opportunity probable to capitalize the surplus glycerol obtained, for numerous applications.

    The Sustainable Development Goals (SDGs) have placed great emphasis on the need for much greater social inclusion, and on making deliberate efforts to reach marginalized groups. People with disabilities are often marginalized through their lack of access to a range of services and opportunities. Assistive products can help people overcome impairments and barriers enabling them to be active, participating and productive members of society. Assistive products are vital for people with disabilities, frailty and chronic illnesses; and for those with mental health problems, and gradual cognitive and physical decline characteristic of aging populations. This paper illustrates how the achievement of each of the 17 SDGs can be facilitated by the use of assistive products. Without promoting the availability of assistive products the SDGs cannot be achieved equitably. We highlight how assistive products can be considered as both a mediator and a moderator of SDG achievement. We also briefly describe how the Global Cooperation on Assistive Technology (GATE) is working to promote greater access to assistive products on a global scale.

  3. Conceptual and operational understanding of learning for sustainability: a case study of the beef industry in north-eastern Australia.

    Extensive attention has been given to understanding learning processes that foster sustainability. Despite this focus there is still limited knowledge of learning processes that create changes in perspectives and practices. This paper aims to increase understanding of learning processes in the context of sustainability and refers to the beef industry in north-eastern Australia. A framework based on adult learning theories was developed and used to analyse the what, why and how of beef producers' learning to improve land condition. Twenty-eight producers were interviewed face-to-face and another 91 participated in a telephone survey. Most beef producers were motivated to learn due to perceived problems with existing practices and described mainly learning new skills and techniques to improve production. Beef producers main learning sources were their own experiences, observing others' practices and sharing experiences with peers and family members. Results showed that organised collective learning, adversity and active experimentation with natural resource management skills and techniques can facilitate critical reflection of practices, questioning of the self, others and cultural norms and an enhanced sense of environmental responsibility.

  9. Making Sustainable Consumption and Production the Core of Sustainable Development Goals

    Directory of Open Access Journals (Sweden)

    Lewis Akenji

    2014-01-01

    Full Text Available This paper argues that sustainable consumption and production (SCP should play a prominent role in the formulation and implementation of the sustainable development goals (SDGs and discusses how this could be practically done. Unsustainable patterns of consumption and production have been declared the primary cause of environmental deterioration. This was clearly recognized already at the United Nations Conference on Environment and Development (or the Rio Summit in 1992; and this recognition has been reconfirmed in all high-level sustainability meetings since then. SCP aims to change these patterns; it is a policy agenda for addressing the root causes of our ecological predicament, while, at the same time, providing for human wellbeing and prosperity. Drawing from international agreements, practical policy experience and research from a range of disciplines, the paper provides a clarifying framework for scientifically robust, policy-relevant and practical goal-setting for SCP within the SDGs. Special attention is given to how SCP in the SDGs can create synergies with other international policy initiatives. The paper explores the advantages and disadvantages of two possible options for reflecting SCP in the SDGs framework: (i SCP as a stand-alone goal; and (ii SCP as a cross-cutting objective, embedded within relevant goals. While these two options are not necessarily mutually exclusive, given the competing number of issues for prioritization and the fact that a 10-Year Framework of Programs on SCP has also recently been established, it is hardly foreseeable that both options can be realized. The paper further proposes a set of basic principles for SCP at the global level and makes recommendations towards the formulation of indicators supporting SCP objectives in the SDGs.

    2015-01-01

    Full Text Available The world energy crisis and increased greenhouse gas emissions have driven the search for alternative and environmentally friendly renewable energy sources. According to life cycle analysis, microalgae biofuel is identified as one of the major renewable energy sources for sustainable development, with potential to replace the fossil-based fuels. Microalgae biofuel was devoid of the major drawbacks associated with oil crops and lignocelluloses-based biofuels. Algae-based biofuels are technically and economically viable and cost competitive, require no additional lands, require minimal water use, and mitigate atmospheric CO2. However, commercial production of microalgae biodiesel is still not feasible due to the low biomass concentration and costly downstream processes. The viability of microalgae biodiesel production can be achieved by designing advanced photobioreactors, developing low cost technologies for biomass harvesting, drying, and oil extraction. Commercial production can also be accomplished by improving the genetic engineering strategies to control environmental stress conditions and by engineering metabolic pathways for high lipid production. In addition, new emerging technologies such as algal-bacterial interactions for enhancement of microalgae growth and lipid production are also explored. This review focuses mainly on the problems encountered in the commercial production of microalgae biofuels and the possible techniques to overcome these difficulties.

    Full Text Available There is not enough land for the current bioenergy production process because of its low annual yield per unit land. In the present paper, an integrated biomass production and conversion process for sustainable bioenergy is proposed and analyzed. The wastes from the biomass conversion process, including waste water, gas and solid are treated or utilized by the biomass production process in the integrated process. Analysis of the integrated process including the production of water hyacinth and digestion for methane in a tropical area demonstrates several major advantages of the integrated process. (1 The net annual yield of methane per unit land can reach 29.0 and 55.6 km3/h for the present and future (2040 respectively, which are mainly due to the high yield of water hyacinth, high biomethane yield and low energy input. The land demand for the proposed process accounts for about 1% of the world’s land to meet the current global automobile fuels or electricity consumption; (2 A closed cycle of nutrients provides the fertilizer for biomass production and waste treatment, and thus reduces the energy input; (3 The proposed process can be applied in agriculturally marginal land, which will not compete with food production. Therefore, it may be a good alternative energy technology for the future.

    Policies at multiple levels pronounce the need to encompass both social and ecological systems in governance and management of natural capital in terms of resources and ecosystems. One approach to knowledge production and learning about landscapes as social-ecological systems is to compare multiple case studies consisting of large spaces and places. We first review the landscape concepts' biophysical, anthropogenic, and intangible dimensions. Second, we exemplify how the different landscape concepts can be used to derive measurable variables for different sustainability indicators. Third, we review gradients in the three dimensions of the term landscape on the European continent, and propose to use them for the stratification of multiple case studies of social-ecological systems. We stress the benefits of the landscape concepts to measure sustainability, and how this can improve collaborative learning about development toward sustainability in social-ecological systems. Finally, analyses of multiple landscapes improve the understanding of context for governance and management.

    When learning a new math concept, should learners be first taught the concept and its associated procedures and then solve problems, or solve problems first even if it leads to failure and then be taught the concept and the procedures? Two randomized-controlled studies found that both methods lead to high levels of procedural knowledge. However, students who engaged in problem solving before being taught demonstrated significantly greater conceptual understanding and ability to transfer to novel problems than those who were taught first. The second study further showed that when given an opportunity to learn from the failed problem-solving attempts of their peers, students outperformed those who were taught first, but not those who engaged in problem solving first. Process findings showed that the number of student-generated solutions significantly predicted learning outcomes. These results challenge the conventional practice of direct instruction to teach new math concepts and procedures, and propose the possibility of learning from one's own failed problem-solving attempts or those of others before receiving instruction as alternatives for better math learning. © 2014 Cognitive Science Society, Inc.

    Sustainability of bioenergy is often indicated by the neutrality of emissions at the conversion site while the feedstock production site is assumed to be carbon neutral. Recent research shows that sustainability of bioenergy systems starts with feedstock management. Even if sustainable forest management is applied, different management types can impact ecosystem services substantially. This study examines different sustainable forest management systems together with an optimal planning of green-field bioenergy plants in the Alps. Two models - the biophysical global forest model (G4M) and a techno-economic engineering model for optimizing renewable energy systems (BeWhere) are implemented. G4M is applied in a forward looking manner in order to provide information on the forest under different management scenarios: (1) managing the forest for maximizing the carbon sequestration; or (2) managing the forest for maximizing the harvestable wood amount for bioenergy production. The results from the forest modelling are then picked up by the engineering model BeWhere, which optimizes the bioenergy production in terms of energy demand (power and heat demand by population) and supply (wood harvesting potentials), feedstock harvesting and transport costs, the location and capacity of the bioenergy plant as well as the energy distribution logistics with respect to heat and electricity (e.g. considering existing grids for electricity or district heating etc.). First results highlight the importance of considering ecosystem services under different scenarios and in a geographically explicit manner. While aiming at producing the same amount of bioenergy under both forest management scenarios, it turns out that in scenario (1) a substantially larger area (distributed across the Alps) will need to be used for producing (and harvesting) the necessary amount of feedstock than under scenario (2). This result clearly shows that scenario (2) has to be seen as an "intensification

    Full Text Available Interest in sustainable learning has been growing over the past 20 years but it has never been determined whether students—whose learning we are trying to sustain—can perceive either the sustainability of their learning or any of the features of this construct. A four-item survey was developed based on a published definition of “sustainable learning”, and was sent to the 12 graduate students who have completed a new seminar in ethical reasoning. A thematic analysis of the narrative responses was submitted to a degrees-of-freedom analysis to determine the level and type of evidence for student perception of sustainability. Respondents (n = 9 endorsed each of the four dimensions of sustainable learning—and each gave examples for each dimension outside of, and after the end of, the course. One respondent endorsed all dimensions of sustainable learning, but was uncertain whether the course itself led to one particular sustainability dimension. While these results must be considered preliminary because our sample is small and the survey is the first of its kind, they suggest that graduate students can and do perceive each of the four features of sustainability. The survey needs refinement for future/wider use; but this four-dimensional definition could be useful to develop and promote (and assess sustainable learning in higher education.

    Full Text Available Conventional agricultural production is denoted by high levels of chemisation, strait specialised production, high yields and low costs per production unit, however this production causes risky interventions, which could affect negatively on environment and human health Research results indicate possibilities for growing vegetables in alternative systems, less risky for environment with satisfying economic success. The aim of this research was to determine economic success of organic, sustainable and conventional production of tomato in the Mediterranean area of Republic Croatia. Bianual research was conducted during 2002/2003. During vegetation we examined parameters of growth, marketable yields and costs for materials, work and machinery which are used in economic analysis. Economical analysis of tomatoes production indicate worst results in organic production system. Loses in tomatoes organic production were consequences of two main factors: lower marketed yield and equal product price for all three production types. Lower yields in organic production were expected, therefore bad financial results were caused by mainly low market prices, which do not validate quality and food safety. Therefore financial success is preconditioned by higher market validation, which can be obtained through market analysis and product development. Consumer awareness about organic agriculture is still very weak and this point requires further attention. The link between organic agriculture and the environment/nature protection is missing too. The purchase of organic food is influenced by the level of information and knowledge of consumers with reference to these products. Doubts about the truthfulness and significance of some data were raised by main places where organic food is purchased, since an excessive greatest limitations are high prices and a low level of information to consumers. Current standard of life of most Croatian consumers does not permit them to

    Kircher, Manfred

    2015-12-01

    In the sectors of biofuel and renewable chemicals the big feedstock demand asks, first, to expand the spectrum of carbon sources beyond primary biomass, second, to establish circular processing chains and, third, to prioritize product sectors exclusively depending on carbon: chemicals and heavy-duty fuels. Large-volume production lines will reduce greenhouse gas (GHG) emission significantly but also low-volume chemicals are indispensable in building 'low-carbon' industries. The foreseeable feedstock change initiates innovation, securing societal wealth in the industrialized world and creating employment in regions producing biomass. When raising the investments in rerouting to sustainable biofuel and chemicals today competitiveness with fossil-based fuel and chemicals is a strong issue. Many countries adopted comprehensive bioeconomy strategies to tackle this challenge. These public actions are mostly biased to biofuel but should give well-balanced attention to renewable chemicals as well. Copyright © 2015 Elsevier Ltd. All rights reserved.

    A sustainable program lives on past its initial funding cycle, and develops a network of users that ensures continued life, either by fees, advertising revenue, or by making the program more successful in later sponsored grants. Teachers like free things, so having a sponsor for products such as lithographs or CD-Roms is key to wide distribution. In 1994 we developed “Space Update®”, under the NASA “Public Use of the Internet” program. It has new editions annually, with over 40,000 distributed so far (many purchased but most free at teacher and student workshops). In 1996 we created a special edition “Space Weather®”, which includes the space weather module from Space Update plus other resources. Initially developed with funding from the IMAGE mission, it is now sponsored by Cluster and MMS. A new edition is published annually and distributed in the “Sun-Earth Day” packet; total distribution now exceeds 180,000. “Earth Update” was created in 1999 under cooperative agreement “Museums Teaching Planet Earth”. It now has a total distribution of over 20,000. Both Earth Update and Space Update were developed to be museum kiosk software, and more than 15 museums have them on display. Over 4,000 users are active in our e-Teacher network and 577 in our museum educator network. Although these can certainly be considered successful because of their longevity and user base, we have had a far more dramatic sustainable program arise in the last six years… the “Discovery Dome®”. Invented at HMNS and developed under NASA Cooperative Agreement “Immersive Earth”, this dome was the first digital portable planetarium that also showed fulldome movies with an interactive interface (first shown to the public at the Dec 2003 AGU meeting).

    Full Text Available Among the various renewable energy sources, biohydrogen is gaining a lot of traction as it has very high efficiency of conversion to usable power with less pollutant generation. The various technologies available for the production of biohydrogen from lignocellulosic biomass such as direct biophotolysis, indirect biophotolysis, photo, and dark fermentations have some drawbacks (e.g., low yield and slower production rate, etc., which limits their practical application. Among these, metabolic engineering is presently the most promising for the production of biohydrogen as it overcomes most of the limitations in other technologies. Microbial electrolysis is another recent technology that is progressing very rapidly. However, it is the dark fermentation approach, followed by photo fermentation, which seem closer to commercialization. Biohydrogen production from lignocellulosic biomass is particularly suitable for relatively small and decentralized systems and it can be considered as an important sustainable and renewable energy source. The comprehensive life cycle assessment (LCA of biohydrogen production from lignocellulosic biomass and its comparison with other biofuels can be a tool for policy decisions. In this paper, we discuss the various possible approaches for producing biohydrogen from lignocellulosic biomass which is an globally available abundant resource. The main technological challenges are discussed in detail, followed by potential solutions.

    The global livestock industry is charged with providing sufficient animal source foods to supply the global population while improving the environmental sustainability of animal production. Improved productivity within dairy and beef systems has demonstrably reduced resource use and greenhouse gas emissions per unit of food over the past century through the dilution of maintenance effect. Further environmental mitigation effects have been gained through the current use of technologies and practices that enhance milk yield or growth in ruminants; however, the social acceptability of continued intensification and use of productivity-enhancing technologies is subject to debate. As the environmental impact of food production continues to be a significant issue for all stakeholders within the field, further research is needed to ensure that comparisons among foods are made based on both environmental impact and nutritive value to truly assess the sustainability of ruminant products.

  11. How can we improve the environmental sustainability of poultry production?

    Leinonen, Ilkka; Kyriazakis, Ilias

    2016-08-01

    The review presents results of recent life cycle assessment studies aiming to quantify and improve the environmental performance of UK poultry production systems, including broiler meat, egg and turkey meat production. Although poultry production has been found to be relatively environmentally friendly compared with the production of other livestock commodities, it still contributes to environmental impacts, such as global warming, eutrophication and acidification. Amongst different sub-processes, feed production and transport contributes about 70 % to the global warming potential of poultry systems, whereas manure management contributes about 40-60 % to their eutrophication potential and acidification potential, respectively. All these impacts can be reduced by improving the feed efficiency, either by changing the birds through genetic selection or by making the feed more digestible (e.g. by using additives such as enzymes). However, although genetic selection has the potential to reduce the resources needed for broiler production (including feed consumption), the changing need of certain feed ingredients, most notably protein sources as a result of changes in bird requirements may limit the benefits of this strategy. The use of alternative feed ingredients, such as locally grown protein crops and agricultural by-products, as a replacement of South American grown soya, can potentially also lead to improvements in several environmental impact categories, as long as such feeding strategies have no negative effect on bird performance. Other management options, such as improving poultry housing and new strategies for manure management have also the potential to further improve the environmental sustainability of the poultry industries in Europe.

  12. Microalgal cultivation and utilization in sustainable energy production

    Energy Technology Data Exchange (ETDEWEB)

    2012-07-01

    Microalgae are a promising feedstock for biofuel and bioenergy production due to their high photosynthetic efficiencies, high growth rates and no need for external organic carbon supply. However, microalgal biomass cultivation for energy production purposes is still rare in commercial scale. Further research and development is needed to make microalgal derived energy sustainable and economically competitive. This work investigated cultivation of fresh water microalga Chlorella vulgaris and marine microalga Dunaliella tertiolecta and their utilization in production of hydrogen, methane, electricity, butanol and bio-oil after bulk harvesting the biomass. Growth of the two microalgae was studied in five different photobioreactor (PBR) configurations especially concentrating on the quantification and characterization of heterotrophic bacteria in non-axenic microalgal cultivations and microalgal utilization of different nitrogen sources. Anaerobic cultures used for the energy conversion processes were enriched from a mesophilic municipal sewage digester separately for production of H{sub 2}, CH{sub 4} and electricity from the two microalgal species. After culture enrichment, energy conversion yields of microalgal biomass to the different energy carriers were compared. In summary, this study demonstrated that both C. vulgaris and D. tertiolecta can be used for production of Hv(2), CHv(4), electricity, butanol and lipids. Based on this study C. vulgaris is more suitable for bioenergy production than D. tertiolecta. Depending on cellular lipid content, lipid utilization for bio-oil production and anaerobic digestion were the most potent means of converting C. vulgaris biomass to energy. The study also revealed diverse microbial communities in non-axenic microalgal photobioreactor cultures and in anaerobic consortia converting microalgal biomass to energy carriers

    Through its Global Action Plan for Influenza Vaccines (GAP), the World Health Organization (WHO) in collaboration with the United States Department of Health and Human Services has produced a checklist to support policy-makers and influenza vaccine manufacturers in identifying key technological, political, financial, and logistical issues affecting the sustainability of influenza vaccine production. This checklist highlights actions in five key areas that are beneficial for establishing successful local vaccine manufacturing. These five areas comprise: (1) the policy environment and health-care systems; (2) surveillance systems and influenza evidence; (3) product development and manufacturing; (4) product approval and regulation; and (5) communication to support influenza vaccination. Incorporating the checklist into national vaccine production programmes has identified the policy gaps and next steps for countries involved in GAP's Technology Transfer Initiative. Lessons learnt from country experiences provide context and insight that complement the checklist's goal of simplifying the complexities of influenza prevention, preparedness, and vaccine manufacturing.

    2017-09-19

    Coccidiosis is a self-limiting disease that is universally present in poultry operations, causing extensive damage to the intestinal lining of the bird. Global economic losses from coccidiosis are estimated to be $3 billion per year. In-feed anticoccidial use has been the predominant form of coccidiosis control. However, due to widespread emergence of antimicrobial resistance, concerns have been raised regarding the safety of anticoccidials and the potential impact on human, animal, and environmental health. To investigate the benefits, risks, and alternatives to anticoccidial use, a comprehensive review of recent literature was conducted. Several live vaccines are available, which, when used in combination with anticoccidials, have been shown to help restore sensitivity of infective parasites. However, their use has been limited because of increased cost; increased susceptibility to bacterial enteritis; challenges with consistent application; and slow development of immunity. Various alternative feed products are available, but do not have a direct anticoccidial effect, and few studies have demonstrated consistent field efficacy of these products. Consumer and environmental safety of anticoccidials is monitored and assessed by governing bodies. Furthermore, there is a lack of current evidence to indicate that bacterial resistance poses a public health concern. The findings from this review indicate that in the absence of alternatives, poultry production is optimized by using anticoccidials, benefiting all three pillars of sustainability, including social (bird health, welfare, and food safety), economic (production efficiency), and environmental aspects.

    Velarde, Antonio; Fàbrega, Emma; Blanco-Penedo, Isabel; Dalmau, Antoni

    2015-11-01

    Animal welfare is an important pillar of sustainability in meat production and is associated with other aspects of this concept, such as animal health, productivity, food safety, food quality and efficiency from a cost of production perspective. These interactions are present at all stages of the production cycle, from the beginning of the animals' farm life until their slaughter. On farm, some of the main welfare issues are related to neonatal mortality and low level of sensory input, which are likely to engender stereotypes and injurious behaviours, such as tail-biting. Pre-slaughter handling refers to the interaction between humans and animals prior to and during transport and at slaughter. Strategies to reduce pre-slaughter stress will benefit carcass and meat quality, being the training of stockpeople one of the most cost-effective policies to improve animal welfare. These strategies include also the implementation of standard monitoring procedures to detect signs of consciousness after stunning, before sticking and during bleeding until death occurs.

  5. Cationization of Alpha-Cellulose to Develop New Sustainable Products

    Directory of Open Access Journals (Sweden)

    Ana Moral

    2015-01-01

    Full Text Available Papermaking has been using high quantities of retention agents, mainly cationic substances and organic compounds such as polyamines. The addition of these agents is related to economic and environmental issues, increasing contamination of the effluents. The aim of this work is to develop a cationic polymer for papermaking purposes based on the utilization of alpha-cellulose. The cationization of mercerized alpha-cellulose with 3-chloro-2-hydroxypropyltrimethylammonium chloride (CHPTAC is governed by a pseudo-second-order reaction. The initial amorphous fraction of cellulose is reacted with CHPTAC until the equilibrium value of nitrogen substitution is reached. Nitrogen is incorporated as a quaternary ammonium group in the polymer. Also, the kinetic constant increased with decreasing crystallinity index, showing the importance of the previous alkalization stage. The use of modified natural polysaccharides is a sustainable alternative to synthetic, nonbiodegradable polyelectrolytes and thus is desirable with a view to developing new products and new processes.

  6. From eco-sustainability to risk assessment of aquaculture products.

    Science.gov (United States)

    Gandini, G; Ababouch, L; Anichini, L

    2009-09-01

    The increasing demand for fishery products and the technical and commercial opportunities now available make the development of aquaculture an important subject for the policy of the fishery sector, in particular concerning aspects of its environmental and ecological sustainability. The latest studies show that it is possible to apply an ecological approach to the aquaculture sector and hence increase the interactions between fisheries and other activities such as fish/molluscs, fish/seaweed, rice-growing/fish. In this way we take part in the improvement of the environment thanks to the recycling of organic food, the reduction of pesticide use and the control of environmental euthrophication. In order to support and facilitate trade, but at the same time ensure the safety and quality of products, a harmonization of the policies for food safety protecting the products throughout the whole food chain is required (from the sea to the table). The above mentioned policy, based on scientific knowledge, relies on the analysis of risks from the competent Authorities and on the proper application of HACCP from the industries of the sector.

  7. GRASSROOTS URBAN COLLECTIVE ACTION IN AGROECOLOGICAL PRODUCTION TOWARDS SUSTAINABILITY

    Directory of Open Access Journals (Sweden)

    Juliana Merçon

    2013-03-01

    Full Text Available The general purpose of this article is to contribute to a broader comprehension of collective grassroots processes that generate effective social and environmental transformations in the practices of urban communities. We start with a brief analysis of the concept of ‘ecological footprint’, which has been widely used as a way of measuring sustainability. It will be shown, however, that there are limitations to the calculations of the ecological footprint, some of which are directly related to agroecological forms of production. Various environmental and social benefits of community agroecological production in the cities are then described and the importance of grassroots forms of organisation is reinforced. In the last sections we present the activities, results and challenges of an urban collective project developed in the city of Morelia, Mexico. The ways in which the Jícara Project changed community practices in reference to the production and use of resources, mental habits, communicative styles, and forms of collective organisation are discussed. In conclusion, we argue that the ecological, intellective and relational transformations promoted by the Jícara Project offer us a proof of what can be achieved through grassroots self-organised urban collectives.

    Implementations of evidence-based mental health practices often disappear quickly, and few studies have examined sustainment. Since 2001, the Individual Placement and Support (IPS) learning community has promoted dissemination, implementation, sustainment, and expansion of IPS by using multiple strategies: online training, in-person training and technical assistance, technical assistance teleconferences, annual meetings, stakeholder conference calls, fidelity assessments, and transparency of outcomes. This study examined sustainment of IPS over a two-year period among programs in the learning community in the United States. The authors interviewed IPS team leaders in 129 programs actively participating in the learning community in 2012 and 2014. The structured interview addressed questions about program status, funding, and quality improvement activities. Simultaneously, the learning community tracked program-level data on IPS fidelity and employment rates. The study examined two-year program sustainment and changes in employment rates, fidelity, funding, and quality improvement activities. In 2012, 129 participating sites had been active for an average of 4.5 years. At two-year follow-up, 124 (96%) sites were sustained. The sustaining sites maintained quality improvement activities, expanded funding sources, and increased employment rates (41% to 43%; p=.04) and fidelity scores (103.8 to 108.4; p=.002). Nearly all programs participating in a learning community in 2012 continued to provide IPS services over the next two years, exceeding sustainment rates for evidence-based practices reported in the literature. Quality indicators also improved, suggesting that learning community activities fostered sustainment and quality. Controlled studies must compare specific learning community approaches with usual methods of sustainment.

  1. Economic Benefits of Sustainable Agricultural Production: The Case of Integrated Pest Management in Cabbage Production

    Directory of Open Access Journals (Sweden)

    Mad Nasir Shamsudin

    2010-01-01

    Full Text Available Environmental protection is a basic element of sustainable agricultural development. Agricultural production practices, however, can cause negative externalities. One main concern of the externality is the negative effects of pesticide use. This has motivated the application of Integrated Pest Management (IPM program. This study attempts to evaluate the economic benefits of IPM to address the widespread misuse of pesticides in cabbage production. IPM application in cabbage production includes initiatives on the optimal use of pesticides, complementary weed control strategies, and alternative cultural and biological controls. Results of this study showed that the programme would generate economic benefits which include improvements in water quality, food safety, pesticide application safety, and long term sustainability of pest management systems. Thus there is justification for public investment of resources in training and educational programs to increase awareness about IPM and promote IPM adoption.

  5. Knowledge and technologies for sustainable intensification of food production.

    Science.gov (United States)

    Flavell, Richard

    2010-11-30

    Knowledge and technologies will always continue to be developed, as they have always, to bring new efficiencies to plant breeding and crop production, which suffer from many constraints and inefficiencies. These constraints need to be overcome throughout the world to help increase the rate of improvements in food production and intensify production on less land. The recent discoveries and technical innovations that are revealing the full complement of genes in crops, the ability to define genetic variation and use DNA markers to follow chromosome segments with known functions through breeding programmes are leading to new efficiencies in breeding. The ability to isolate and redesign genes and transfer them into different plants also offers the breeder solutions to several key limitations. These benefits are described together with some of the current issues associated with the use of transgenes. Generation after generation can look forward to new knowledge and technologies, many of which we cannot know at present, and thus there is no reason to be despondent about meeting future goals, if the right decisions and investments are made globally and locally. These decisions include putting optimal use of land at the top of the world agenda to sustain both the planet and an adequate quality of life for mankind. As always has been the case, more investments are urgently required into the dissemination of successful technologies in crop breeding and production, into teaching and training as well as into innovative research. Failure to invest adequately in innovative technologies will leave future decision-makers and citizens with fewer options and greatly enhance the risks for mankind and a healthy planet.

However, biomass is not a limitless resource or one without environmental and social impacts. Therefore, while it is important to use biomass and grow a bio-based economy, displacing the unsustainable petroleum basis of energy and chemical production, any resource must be used effectively to reduce waste. Standards have been developed to support the bio-based product market in order to achieve this aim. However, the design of bio-based products has not received the same level of attention. Reported here are the first steps towards the development of a framework of understanding which connects product design to resource efficiency. Research and development scientists and engineers are encouraged to think beyond simple functionality and associate value to the potential of materials in their primary use and beyond.

    Full Text Available Given the search for new solutions to better prepare cities for the future, in recent years, urban agriculture (UA has gained in relevance. Within the context of UA, innovative organizational and technical approaches are generated and tested. They can be understood as novelties that begin a potential innovation process. This empirical study is based on 17 qualitative interviews in the U.S. (NYC; Philadelphia, PA, USA; Chicago, IL, USA. The aim was to identify: (i the most relevant areas of learning and innovation; (ii the drivers of innovation; (iii the applied novelties and their specific approach to overcoming the perceived obstacles; (iv the intrinsic challenges that practitioners face in the innovation process; and (v the novelties’ potential to contribute to sustainability and societal change. As the results of the study demonstrate, learning and innovation in UA occur predominantly in four areas, namely, “financing and funding”, “production, technology and infrastructure”, “markets and demands” and “social acceptance and cultural learning”. The described novelties include approaches to enhance the positive impacts of practicing agriculture within urban areas, and some of them have the potential to contribute to societal change and open up opportunities for social learning processes.

  17. Impacts of Sustained Institutional Participation in Service-Learning: Perspectives from faculty, staff and administrators

    Full Text Available The movement for greater civic engagement in higher education in the United States has taken hold across the core academic missions of teaching, research and service. One manifestation of this movement has been growing participation in service-learning, a teaching method grounded in community-university partnerships in which students provide services that simultaneously address community-identified concerns and meet key learning objectives. In order to assess the benefits of long-term sustained institutional involvement in service-learning, in 2007–2008 we interviewed 23 faculty members, staff and administrators from 16 academic institutions that had participated in a national demonstration program for service-learning, which ended in 1998. We found that 15 of these institutions had sustained service-learning to some degree and 12 had integrated service-learning into the curriculum, with varying degrees of institutional support. Interview participants described five main impacts of their institutions’ sustained participation in service-learning: 1 increased community engagement and community-engaged scholarship, and increased valuation of both, among participating faculty members; 2 greater capacity for community-university partnerships among academic and community partners; 3 improved community-university relations; 4 diffusion of service-learning and/or principles of community-university partnerships to other departments and schools; and 5 recruitment of students seeking community engagement opportunities. This study provides evidence that sustained institutional participation in service-learning can foster an understanding of the scholarly value of community-engaged teaching and research among participating faculty, and increase community-engaged activities at participating academic institutions. These findings suggest that funding agencies, faculty members and academic administrators can use service-learning as a strategy to foster a

    Vlasova, Tatiana; Volkov, Sergey

    2016-09-01

    The paper is an attempt to tie together main biogeophysical and social science projects under the auspice of interdisciplinary sustainability science development. Special attention is put to the necessity of the transdisciplinary knowledge co-production based on activities and problem-solutions approaches. It puts attention to the role of monitoring activities in sustainability interdisciplinary science and transdisciplinary knowledge evolution in the Arctic. Socially focused monitoring named Socially-Oriented Observations creating a transdisciplinary space is viewed as one of sources of learning and transformations towards sustainability making possible to shape rapid changes happening in the Arctic based on sustainability knowledge co-production. Continuous Socially-Oriented Observations integrating scientific, education and monitoring methods enables to define adaptation and transformation pathways in the Arctic - the most rapidly changing region of our planet. Socially-Oriented Observations are based on the existing and developing interdisciplinary scientific approaches emerged within natural science and social science projects, sustainable development and resilience concepts putting principle attention to building sustainable and resilient socio-ecological systems. It is argued that the Arctic sustainability science is a valuable component of the whole and broader system of the Arctic Sustainability knowledge co-produced with the help of transdisciplinary approaches integrating science, local/traditional knowledge, entrepreneurship, education, decision-making. Socially-Oriented Observations are designed to be a transdisciplinary interactive continuous participatory process empowering deliberate choices of people that can shape the changes and enable transformation towards sustainability. Approaches of Socially-Oriented Observations and methods of implementation that have been developed since the IPY 2007/2008 and being practiced in different regions of the

  20. Pedagogies to Achieve Sustainability Learning Outcomes in Civil and Environmental Engineering Students

    Directory of Open Access Journals (Sweden)

    Angela R. Bielefeldt

    2013-10-01

    Full Text Available The civil and environmental engineering disciplines have identified the levels of knowledge about sustainability that are desirable for students to achieve as they graduate with a bachelor’s degree, as well as sustainability-related competencies to be obtained during a master’s degree, and on-the-job, prior to professional licensure. Different pedagogies are better suited to help students attain these levels of cognitive ability, while also developing affective outcomes. This paper provides examples of different methods that have been used at one institution to educate engineering students about sustainability, supported with data that indicates whether the method successfully achieved the targeted learning outcomes. Lectures, in-class active learning, readings, and appropriately targeted homework assignments can achieve basic sustainability knowledge and comprehension by requiring students to define, identify, and explain aspects of sustainability. Case studies and the application of software tools are good methods to achieve application and analysis competencies. Project-based learning (PBL and project-based service-learning (PBSL design projects can reach the synthesis level and may also develop affective outcomes related to sustainability. The results provide examples that may apply to a wider range of disciplines and suggest sustainability outcomes that are particularly difficult to teach and/or assess.

    Use of a sustained visual attention task to determine children "at risk" for learning problems. The purpose in the study was to compare the sustained visual attention performance of 42 first grade children on a 9.5 minute continuous performance test, as measured by error rate and off-task visual behaviors, e.g., off-task looking time and number of fixations off the task, with a measure of impulsivity and a teacher rating scale of classroom behavior designed to identify children with potential learning disabilities. The present findings suggest that the measurement of "off-task looking time" and "off-task fixations" during a sustained visual attention test are significantly related to the classroom teacher's observation of personal-social behavior and the child's decision making style. This approach for measuring sustained attention has potential use as a clinical tool in identifying and monitoring treatment methodologies for children considered "at risk" for attention and learning problems.

    The Okayama Education for Sustainable Development (ESD) Project is an ongoing initiative in Okayama City, Japan, established in 2005 by the Regional Centre of Expertise (RCE) Okayama and the Okayama Municipal Government with the aim "to create a community where people learn, think and act together towards realising a sustainable society". With a diverse participant base of over 240 organisations - including community learning centres (kominkans), schools, universities and non-governmental organisations (NGOs) - this initiative has administered numerous programmes. It has engaged a large and diverse group of citizens from Okayama City in exploring sustainability issues through collective discussion, envisioning and practice with the aim of living more sustainable lives. The decade-long experience of the Okayama ESD Project has gained international attention, and the "Okayama Model" is considered an inspiring example of community-based ESD due to the positive changes it has supported. In this article, the Okayama ESD Project is presented as a case study on effective social learning for sustainability. In particular, the practical efforts made are examined to provide insights into how various elements of a social learning process were strengthened and linked to create active learning cycles among community members. In addition, the conditions for creating an effective learning community are investigated, while the practical actions taken are examined in relation to creating an effective social learning process. Finally, this article presents the important role which social learning has played in Okayama City's transition to sustainability and identifies the key efforts made to address and link each of these elements of social learning into a dynamic cycle.

    To implement policies about sustainable landscapes and rural development necessitates social learning about states and trends of sustainability indicators, norms that define sustainability, and adaptive multi-level governance. We evaluate the extent to which social learning at multiple governance levels for sustainable landscapes occur in 18 local development initiatives in the network of Sustainable Bergslagen in Sweden. We mapped activities over time, and interviewed key actors in the network about social learning. While activities resulted in exchange of experiences and some local solutions, a major challenge was to secure systematic social learning and make new knowledge explicit at multiple levels. None of the development initiatives used a systematic approach to secure social learning, and sustainability assessments were not made systematically. We discuss how social learning can be improved, and how a learning network of development initiatives could be realized.

    As part of a systemic assessment toward social sustainability of egg production, we have reviewed current knowledge about the environmental impacts of egg production systems and identified topics requiring further research. Currently, we know that 1) high-rise cage houses generally have poorer air quality and emit more ammonia than manure belt (MB) cage houses; 2) manure removal frequency in MB houses greatly affects ammonia emissions; 3) emissions from manure storage are largely affected by storage conditions, including ventilation rate, manure moisture content, air temperature, and stacking profile; 4) more baseline data on air emissions from high-rise and MB houses are being collected in the United States to complement earlier measurements; 5) noncage houses generally have poorer air quality (ammonia and dust levels) than cage houses; 6) noncage houses tend to be colder during cold weather due to a lower stocking density than caged houses, leading to greater feed and fuel energy use; 7) hens in noncage houses are less efficient in resource (feed, energy, and land) utilization, leading to a greater carbon footprint; 8) excessive application of hen manure to cropland can lead to nutrient runoff to water bodies; 9) hen manure on open (free) range may be subject to runoff during rainfall, although quantitative data are lacking; 10) mitigation technologies exist to reduce generation and emission of noxious gases and dust; however, work is needed to evaluate their economic feasibility and optimize design; and 11) dietary modification shows promise for mitigating emissions. Further research is needed on 1) indoor air quality, barn emissions, thermal conditions, and energy use in alternative hen housing systems (1-story floor, aviary, and enriched cage systems), along with conventional housing systems under different production conditions; 2) environmental footprint for different US egg production systems through life cycle assessment; 3) practical means to mitigate air

    Ethanol produced from pretreatment and microbial fermentation of biomass has great potential to become a sustainable transportation fuel in the near future. First generation biofuel focus on starch (from grain) fermentation, but in the present study that is regarded as a too important food source. In recent years 2nd generation technologies are developed utilizing bulk residues like wheat straw, woody materials, and corn stover. However, there is a need for integrating the biomass starting point into the energy manufacturing steps to secure that bioenergy is produced from local adapted raw materials with limited use of non-renewable fossil fuels. Produced crops can be transformed into a number of useful products using the concept of biorefining, where no waste streams are produced. An advantage of intercropping is that the intercrop components composition can be designed to produce a medium (for microbial fermentation) containing all essential nutrients. Thereby addition of e.g. urea and other fermentation nutrients produced from fossil fuels can be avoided. Intercropping, defined as the growing of two or more species simultaneously on the same area of land, is a cropping strategy based on the manipulation of plant interactions in time and space to maximize growth and productivity. Cereal-legume intercropping data from field trials show the possibility to improve the use of nitrogen resources, because the non fixing species (e.g. wheat) efficiently exploits soil mineral N sources while at the same time atmospheric N from the N{sub 2}-fixing species (e.g. pea) enter the cropping system reducing the need for N fertilizer application. Nitrogen fertilization is responsible for more than 85 % of the greenhouse gas emissions from wheat grain production in Denmark. Increase of fertilizer N supply promotes the growth of wheat and results in a decreased pea N accumulation and a different proportion of intercrop components. Intercropping introduce a dynamic change of plant

    2015-03-01

    Full Text Available One of the difficulties in teaching global sustainability in the introductory political science classes is the different emphases placed on this concept and the absence of the consensus on where the overall balance between environmental protection, economic development, and social justice should reside. Like many fuzzy concepts with which students struggle, teaching sustainability lends itself to pedagogical examination within the scholarship of threshold concepts. This article investigates students’ understanding of sustainability in the seven semesters when the concept of sustainability was introduced via role-playing simulation and compares it with the similar data from a more recent semester when simulation was supplemented with traditional lecture and classroom exercises. Ultimately, our research question is twofold: (1 How do students define a multifaceted concept like global sustainability and (2 what is the better way to teach it – active learning only or active learning in combination with traditional instruction?

    Full Text Available The increasing concerns about the environment and the depletion of natural resources are the main drivers for the growing interest in sustainability. Manufacturing operations are frequently considered to have an adverse effect on the environment. Hence, the sustainable operation of manufacturing facilities is a vital practice to ensure sustainability. The aim of this paper is to find the optimum product mix of a manufacturing facility to maximize its sustainability. A mixed integer non-linear programming model is developed to specify the product mix in order to maximize a proposed sustainability index (SI of a manufacturing facility. The sustainability index comprises the economic, environmental and social pillars of sustainability in a weighted form using the analytic hierarchy process (AHP. The model results allow the identification of the prospective improvements of manufacturing sustainability.

    The successful use of plant biomass for the sustainable production of energy and co-products such as chemicals is critically important for the future of humanity. Large scale exploitation of biomass is needed to decrease the production of greenhouse gases and help mitigate global warming, to provide energy security in the face of declining petroleum reserves, to improve balance of payment imbalances, and to spur local economic development. This volume discusses such uses of plant biomass as well as ways to improve the productivity and composition of plant species, including trees, perennial and annual grasses, oil-producing plants and algae, that have the potential to produce substrates such as sugar, starch, oil and cell walls, as well as energy and co-product substrates. The problems of invasiveness and gene dispersal are discussed, as are ways to mitigate these. Among the topics covered are models for integrated biorefineries to produce many co-product chemicals, the use of corn stover to power ethanol plants, life cycle analysis of biofuels, and criteria for biomass sustainability and certification. This is indeed an exciting and fast-moving time for advocates of plant biomass-based technology. (orig.)

  5. Community research in other contexts: learning from sustainability science.

    In health research, community based participatory research (CBPR) has seen remarkable growth as an approach that overcomes many of the ethical concerns raised by traditional approaches. A community of CBPR scholars is now sharing ideas and devising new approaches to collaborative research. Yet, this is occurring in isolation from similar efforts using different nomenclature and occurring outside of health research areas. There is much to be gained by bringing these parallel discussions together. In sustainability science, for example, scholars are struggling with the question of how stakeholders and scientists can coproduce knowledge that offers useful solutions to complex and urgent environmental problems. Like CBPR in health, sustainability science is denigrated for perceived lack of rigor because of its applied problem focus and lack of positivist approach. Approaches to knowledge creation in sustainability science involve "new" ideas such as wicked problems and agent-based modeling, which would be equally applicable to CBPR. Interestingly, sustainability research is motivated less by recognition of the corrosive effects of the inequality of power than from frustration at how limited the impact of research has been, a perspective that might be useful in CBPR, particularly in conjunction with the use of some borrowed tools of sustainability science such as wicked problem analysis and agent-based modeling. Importantly, the example of sustainability science has the potential to keep CBPR from entering into a new orthodoxy of how research should be done.

    To assess the long-term sustainability of continuing professional development (CPD) training in pharmacy practice and learning behaviors. This was a 3-year posttrial survey of pharmacists who had participated in an unblinded randomized controlled trial of CPD. The online survey assessed participants' perceptions of pharmacy practice, learning behaviors, and sustainability of CPD. Differences between groups on the posttrial survey responses and changes from the trial's follow-up survey to the posttrial survey responses within the intervention group were compared. Of the 91 pharmacists who completed the original trial, 72 (79%) participated in the sustainability survey. Compared to control participants, a higher percentage of intervention participants reported in the sustainability survey that they had utilized the CPD concept (45.7% vs 8.1%) and identified personal learning objectives (68.6% vs 43.2%) during the previous year. Compared to their follow-up survey responses, lower percentages of intervention participants reported identifying personal learning objectives (94.3% vs 68.6%), documenting their learning plan (82.9% vs 22.9%) and participating in learning by doing (42.9% vs 14.3%) in the sustainability survey. In the intervention group, many of the improvements to pharmacy practice items were sustained over the 3-year period but were not significantly different from the control group. Sustainability of a CPD intervention over a 3-year varied. While CPD-trained pharmacists reported utilizing CPD concepts at a higher rate than control pharmacists, their CPD learning behaviors diminished over time.

  7. GM crops, the environment and sustainable food production.

    Today, over 7.1 billion people rely on the earth's resources for sustenance, and nearly a billion people are malnourished, their minds and bodies unable to develop properly. Globally, population is expected to rise to more than 9 billion by 2050. Given the combined pressures of human population growth, the rapidly growing desire for increased levels of consumption, and the continued use of inappropriate technologies, it is not surprising that humans are driving organisms to extinction at an unprecedented rate. Many aspects of the sustainable functioning of the natural world are breaking down in the face of human-induced pressures including our individual and collective levels of consumption and our widespread and stubborn use of destructive technologies. Clearly, agriculture must undergo a redesign and be better and more effectively managed so as to contribute as well as possible to feeding people, while at the same time we strive to lessen the tragic loss of biodiversity and damage to all of its productive systems that the world is experiencing. For GM crops to be part of the solution, biosafety assessments should not be overly politically-driven or a burdensome impedance to delivering this technology broadly. Biosafety scientists and policy makers need to recognize the undeniable truth that inappropriate actions resulting in indecision also have negative consequences. It is no longer acceptable to delay the use of any strategy that is safe and will help us achieve the ability to feed the world's people.

    The demand for petroleum has risen rapidly due to increasing industrialization and modernization of the world. This economic development has led to a huge demand for energy, where the major part of that energy is derived from fossil sources such as petroleum, coal and natural gas. Continued use of petroleum sourced fuels is now widely recognized as unsustainable because of depleting supplies. There is a growing interest in using Jatropha curcas L. oil as the feedstock for biodiesel production because it is non-edible and thus does not compromise the edible oils, which are mainly used for food consumption. Further, J. curcas L. seed has a high content of free fatty acids that is converted in to biodiesel by trans esterification with alcohol in the presence of a catalyst. The biodiesel produced has similar properties to that of petroleum-based diesel. Biodiesel fuel has better properties than petro diesel fuel; it is renewable, biodegradable, non-toxic, and essentially free of sulfur and aromatics. Biodiesel seems to be a realistic fuel for future. Biodiesel has the potential to economically, socially, and environmentally benefit communities as well as countries, and to contribute toward their sustainable development.

    Sustainable production of biofuels cannot be achieved without multiple-use landscapes where food, feed, and fuel can be co-produced without environmental harm. Here we use field level measurements in seven biofuel feedstock production systems grown under similar climatic conditions, but on different soils in two Midwestern (USA) states to understand their relative climatic impacts. We studied annual corn stover, and 6 perennial ecosystems including three polycultures: successional vegetation, restored prairie and a 3-species grass mix; and 3 monocultures: poplar, switchgrass, and miscanthus. All studied ecosystems were grown in replicated plots on moderately fertile soils of SW Michigan and highly fertile soils of central Wisconsin. We measured components of greenhouse gas (GHG) balances over 6 years. On the fertile soil perennial monocultures had GHG emission reductions potentials of 53% relative to fossil fuels, while polycultures had 64% reduction; corn stover had an 84% emissions reduction. Net sequestration ranged from 0.6 MgCO2e ha-1yr-1 (successional vegetation) to 3.1 MgCO2e ha-1yr-1, (corn stover). Among feedstocks produced on less fertile soils, perennial monocultures had GHG emissions reduction of 80%, and polycultures had emission reduction of 54%; miscanthus and poplar exhibited the largest sequestration potentials of 5.9 and 3.9 MgCO2e ha-1yr-1 respectively, while polycultures sequestered less then 1.0 MgCO2e ha-1yr-1 on average and corn stover was intermediate with 1.4 MgCO2e ha-1yr-1. All studied systems averaged energy production of 30 GJ ha-1 yr-1, except miscanthus (71 GJ ha-1 yr-1) and successional vegetation (20 GJ ha-1 yr-1). Our results inform the design of multiple-use landscapes: more fertile soils could produce food and feed with residuals collected for bioethanol production and more marginal soils could be used for various poly- or mono-cultures of purpose grown biofuel feedstocks but with differential climate benefits.

    The aim of the study was to analyze the availability of published radiological e-learning tools and to establish a solution for quality assurance. Substantial pubmed research was performed to identify radiological e-learning tools. 181 e-learning programs were selected. As examples two databases expanding their programs with external links, Compare (n = 435 external links) and TNT-Radiology (n = 1078 external links), were evaluated. A concept for quality assurance was developed by an international taskforce. At the time of assessment, 56.4 % (102 / 181) of the investigated e-learning tools were accessible at their original URL. A subgroup analysis of programs published 5 to 8 years ago showed significantly inferior availability to programs published 3 to 5 years ago (p eLearning-radiology.com was developed by the taskforce and published online. This tool allows authors to present their programs and users to evaluate the e-learning tools depending on several criteria in order to remove inoperable links and to obtain information about the complexity and quality of the e-learning tools. More than 50 % of investigated radiological e-learning tools on the Internet were not accessible after a period of 5 to 8 years. As a consequence, an independent, international tool for quality assurance was designed and published online under www.eLearning-radiology.com .

    Environment and sustainability education processes are often oriented to change and transformation, and frequently involve the emergence of new forms of human activity. However, not much is known about how such change emerges from the learning process, or how it contributes to the development of transformative agency in community contexts. The authors of this article present four cross-case perspectives of expansive learning and transformative agency development in community-based education in southern Africa, studying communities pursuing new activities that are more socially just and sustainable. The four cases of community learning and transformative agency focus on the following activities: (1) sustainable agriculture in Lesotho; (2) seed saving and rainwater harvesting in Zimbabwe; (3) community-based irrigation scheme management in Mozambique; and (4) biodiversity conservation co-management in South Africa. The case studies all draw on cultural-historical activity theory to guide learning and change processes, especially third-generation cultural-historical activity theory (CHAT), which emphasises expansive learning in collectives across interacting activity systems. CHAT researchers, such as the authors of this article, argue that expansive learning can lead to the emergence of transformative agency. The authors extend their transformative agency analysis to probe if and how expansive learning might also facilitate instances of transgressing norms - viewed here as embedded practices which need to be reframed and changed in order for sustainability to emerge.

    2013-06-01

    Rural bioenergy production has accrued interest in recent years. EU pressure for climate change abatement and energy political concerns regarding the availability of fossil fuels, have increased bioenergy production objectives in Finland. In addition, rural regions in Finland have encountered structural changes following EU inclusion, including an emergent interest in auxiliary production lines of which bioenergy production is an example. Local bioenergy production has the potential to increase rural sustainability and provide a model for sustainable rural development and energy production. Focusing on the recent emergence of small-scale farm-related bioenergy production: heat provision from wood fuels and biogas and biodiesel production, this study aims to discover if and how farm-based bioenergy production contributes to sustainable rural development. The study derives from the field of rural studies and evaluates sustainable rural development via the concepts of multifunctionality, embeddedness, ecological modernization and sustainable livelihoods, with a particular focus on social sustainability. The empirical portion of the study is comprised of thematic qualitative interviews of bioenergy producing farmers, and on newspaper and periodical article material. The results demonstrate how rural small-scale bioenergy production can have important positive developmental effects that ameliorate and sustain livelihoods in remote areas. This occurs via the multifunctional benefits of bioenergy production to the producers and local communities. The positive effects include social, economical and environmental aspects and rural bioenergy production can present traits of sustainable rural development, predominantly manifested in the social aspects of increased capabilities and reinforced social networks. There are, however, important differences between the examined production models. As an example of achieving sustainable rural development and livelihoods, heat

    Full Text Available The industry of construction products plays an important role in Europe in promoting the sustainability of the built environment in a life cycle perspective. Within the framework of the European initiatives for a sustainable competitiveness, manufacturers are interested in promoting a life cycle approach along the building chain. However both, institutions and building operators, in general still have to go a long way on designing and applying a sustainable and competitive industrial policy. This paper aims to describe the European background, the regulatory framework, identifying gaps and the actions to be undertaken to promote a market for sustainable products and sustainable buildings. In particular this paper deals with the assessment and communication of the environmental performance of construction products between the operators in the building chain, as a prerequisite for the sustainability of the built environment, and outlines the strategies to implement a proper evaluation and communication process.

    In transitional stage saving rate play an important role in output growth rate as proposed by Krugman. Accumulationists are also right as claiming that learning-by-doing play an important role in TFP growth in NIEs. However, using a CES production technology we can show that the growth model based purely on learning-by-doing is constrained by labor growth rate. If the latter is constant in the long-run, then the growth can not be sustained.

  19. The Role of Sustained Attention in the Production of Conjoined Noun Phrases: An Individual Differences Study

    It has previously been shown that language production, performed simultaneously with a nonlinguistic task, involves sustained attention. Sustained attention concerns the ability to maintain alertness over time. Here, we aimed to replicate the previous finding by showing that individuals call upon sustained attention when they plan single noun phrases (e.g., "the carrot") and perform a manual arrow categorization task. In addition, we investigated whether speakers also recruit sustained attention when they produce conjoined noun phrases (e.g., "the carrot and the bucket") describing two pictures, that is, when both the first and second task are linguistic. We found that sustained attention correlated with the proportion of abnormally slow phrase-production responses. Individuals with poor sustained attention displayed a greater number of very slow responses than individuals with better sustained attention. Importantly, this relationship was obtained both for the production of single phrases while performing a nonlinguistic manual task, and the production of noun phrase conjunctions in referring to two spatially separated objects. Inhibition and updating abilities were also measured. These scores did not correlate with our measure of sustained attention, suggesting that sustained attention and executive control are distinct. Overall, the results suggest that planning conjoined noun phrases involves sustained attention, and that language production happens less automatically than has often been assumed. PMID:26335441

    Full Text Available Research results on the diversity of traditional products of animal origin from certain areas of the Republic of Serbia, provides an opportunity to become part of the sustainable quality development, which would be based on their promotion and protection of local resources. Traditional products of animal origin are different and inseparable from the local identity, typical for nation and its food culture. Through confidence-building, and protection from oblivion, the value of domestic products, had preserved trough centuries-old tradition. Nowadays, each domestic product has its own recognisable taste, representing climate of the Republic of Serbia, from which it comes. Universally accepted model of rural institutional structure does not exist. Instead it accommodates and develops in accordance to needs, possibilities and area specific characteristics. By the efficient protection rural models becomes an investment incentives and contribute to general economic and industrial prosperity of the society.

    This study aimed to engage wide-ranging stakeholders and develop consensus learning objectives for undergraduate and postgraduate medical education. A UK-wide consultation garnered opinions of healthcare students, healthcare educators and other key stakeholders about environmental sustainability in medical education. The policy Delphi approach informed this study. Draft learning objectives were revised iteratively during three rounds of consultation: online questionnaire or telephone interview, face-to-face seminar and email consultation. Twelve draft learning objectives were developed based on review of relevant literature. In round one, 64 participants' median ratings of the learning objectives were 3.5 for relevance and 3.0 for feasibility on a Likert scale of one to four. Revisions were proposed, e.g. to highlight relevance to public health and professionalism. Thirty three participants attended round two. Conflicting opinions were explored. Added content areas included health benefits of sustainable behaviours. To enhance usability, restructuring provided three overarching learning objectives, each with subsidiary points. All participants from rounds one and two were contacted in round three, and no further edits were required. This is the first attempt to define consensus learning objectives for medical students about environmental sustainability. Allowing a wide range of stakeholders to comment on multiple iterations of the document stimulated their engagement with the issues raised and ownership of the resulting learning objectives.

    Full Text Available This study aimed to adopt the perspective of corporate social responsibility (CSR to explore the intention of sustainable product development in Taiwan, as well as leading to the creation of influential factors that affect corporate sustainable product development intention. In this research, the induction analysis was conducted to understand the implementation of sustainable product development, and this was supplemented with questionnaire surveys and in-depth interviews to evaluate developmental intention. In addition, principal component analysis was used for factor analysis and content analysis in the 6 W expression method, leading to the creation of the influential factors. The research results have demonstrated that the factors affecting the intention of corporate sustainable product development include having a sustainable design and a development purpose, a corporate development purpose, sustainable development concepts, a sustainable design value, a sustainability concept, and a manufacturing process quality. For sustainable product development, corporate social responsibility needs to be most concerned with the added value of products, regulation requirements, and accommodation of the industrial chain, costs, and quality.

    The global sustainability aspects are discussed and a method for sustainability analysis in oil and gas production surface facilities is presented. The proposed method requires a multidisciplinary viewpoint and considers social, economic and environmental sustainability aspects during the early design programming and planning phases. Traditionally, Feasibility (Technical and Economical), Environmental Impact Assessment (EIA) and risk (Hazop) analysis are performed separately. On the other hand, the proposed methodology merges economical, environmental and social sustainability analysis; which allows deciding the most globally sustainable scenario. A checklist containing global sustainability aspects (Economical, Social, Environmental, Health, Safety, etc.) and a qualitative analysis of these aspects is suggested. The first step for applying the proposed method consists in checking the aspects and the corresponding suggestions for improving the global sustainability. Secondly, the impact of each aspect on sustainability is verified. Finally, the most important aspects are selected and different scenarios are simulated allowing choosing the most sustainable scenario. The results and conclusions are then presented in a Global Sustainability Report. The proposed analysis was applied to study the sustainability of a small offshore platform design. In this case study, several aspects that could potentially improve sustainability were identified. The simulated scenarios showed that some critical aspects contributed decisively to the global sustainability. These critical aspects are not easily identified if only the traditional economical, environmental and risk analysis are applied. (author)

    Woodhill, Jim

    Drawing on the experience of community based land conservation in Australia, this chapter examines the deeper structural and institutional causes of the unsustainability of modern industrialised society. Social learning is presented as a potential paradigm for engaging with these broader institutional dilemmas. Such a perspective locates the concept of social learning at the heart of current debates about the tensions between sustainable development, democracy and free market ideology. The chapter introduces the themes of risk society and reflexive modernisation as a perspective that can help explain why modern institutions are structurally biased against the ideals of sustainable development. This provides a brief political economic context for then outlining a perspective on social learning that gives particular attention to questions of how to facilitate the design of institutions more supportive of sustainable development.

For the Danish fish farmers the extractive organisms could be the solution for increasing fish production...... and robust mitigation tool for nitrogen removal and hopefully allow for future expansion of sustainable marine fish production in Denmark......., but do the principles of IMTA fully mitigate the nutrient impact from open net-pen fish production at realistic production scales? In this project, commercial scale cultivation of sugar kelp (Saccharina latissima) was investigated with regard to operation, yield, biofilter capacity and mapping...

  6. Sustainable development and social learning: Re-contextualising the space of orientation

    Seddon, Terri

    2016-10-01

    In the lead-up to the 2007 Australian federal election, Labor candidate Kevin Rudd described climate change as the "great moral challenge of our generation". In the years since then, the heat in Australia has been rising - in terms of both temperature and climate politics -, but government action has slowed down. Endorsement of economic growth is prioritised, with only intermittent recognition of environmental costs. At grassroots level, citizens' attitudes are influenced by social norms. This kind of social learning is a major constraint on sustainability. Therefore, it seems useful to consider how educators might help build sustainable futures. To understand how historical context entangles social learning in ways that complicate policies associated with Education for Sustainable Development (ESD) and practices of Education for Sustainability (EfS), the author of this paper draws on the concept of "space of orientation". Focusing on adult education, she traces the contradiction between "globalisation" and "sustainability" through policy logics, relational practices in Australian adult education and the "necessary utopia" which provides a point of reference for making futures. She argues that spaces of orientation are a critical resource in this era of intensifying conflicts of interest between economic priorities of globalisation and environmental priorities intended to slow global warming, because they mediate context and orient learning in ways that clear a path towards sustainability through the entangled histories of this present.

  7. Exploring the Incorporation of Values for Sustainable Entrepreneurship Teaching/Learning

    2013-01-01

    Full Text Available The objective of the “United Nations Decade of Education for Sustainable Development”, during the period 2005 to 2014 is to integrate the principles, values and practices of sustainability in all aspects of education. The aim is to stimulate behavior changes, which will allow the creation of an economic, social and environmentally sustainable future. Sustainable entrepreneurial behavior is relevant for carrying out these changes. This paper tries to find the way to promote a sustainable entrepreneurial vision through the incorporation of new values for teaching/learning of potential entrepreneurs from the moment when the idea is born for creating a for-profit, non-profit or hybrid organization. Generating a change of perspective from the beginning of the entrepreneurship process is sought for fostering the birth of organizations that respect the environment and are responsible when confronting social problems, besides being profitable. All this involves a great challenge to all agents implicated in the process.

    2010-04-01

    Full Text Available Social-emotional learning, character education, and related programs are being implemented in schools with increasing frequency and research supports their short-term effectiveness. However, there has been no empirical work to date that identifies the factors important for the long-term sustainability of programs established as excellent models of implementation. Using a series of case studies of evidence-based social-emotional learning programs implemented successfully for at least five years, this study articulates principles that characterize programs that were found to be well-sustained over time. These principles have implications for practice and serve as starting points for future research.

    To safely and effectively apply artemisinin sustained-release granules to control and prevent algal water-blooms, the effects of artemisinin and its sustained-release granules on freshwater alga (Scenedesmus obliquus (S. obliquus) and Microcystis aeruginosa (M. aeruginosa)), as well as the production and release of microcystins (MCs) were studied. The results showed that artemisinin sustained-release granules inhibited the growth of M. aeruginosa (above 95% IR) and S. obliquus (about 90% IR), with M. aeruginosa more sensitive. The artemisinin sustained-release granules had a longer inhibition effect on growth of pure algae and algal coexistence than direct artemisinin dosing. The artemisinin sustained-release granules could decrease the production and release of algal toxins due to the continued stress of artemisinin released from artemisinin sustained-release granules. There was no increase in the total amount of MC-LR in the algal cell culture medium.

    ‘Environmental and sustainability’ is one of the Program Outcome (PO) designated by the Board of Engineers Malaysia (BEM) as one of the accreditation program requirement. However, to-date the implementation of sustainability elements in engineering programme in the technical universities in Malaysia is within individual faculty's curriculum plan and lack of university-level structured learning pathway, which enable all students to have access to an education in sustainability across all disciplines. Sustainability Graduate Community (SGC) is a framework designed to provide a learning pathway in the curriculum of engineering programs to inculcate sustainability education among engineering graduates. This paper aims to study the required attributes in Sustainability Graduate Community (SGC) framework to produce graduates who are not just engineers but also skilful in sustainability competencies using Global Project Management (GPM) P5 Standard for Sustainability. The development of the conceptual framework is to provide a constructive teaching and learning plan for educators and policy makers to work on together in developing the Sustainability Graduates (SG), the new kind of graduates from Malaysia Technical Universities Network (MTUN) in Malaysia who are literate in sustainability practices. The framework also support the call for developing holistic students based on Malaysian Education Blueprint (Higher Education) and address the gap between the statuses of engineering qualification to the expected competencies from industries in Malaysia in particular by achieving the SG attributes outlined in the framework

    Full Text Available The textile and clothing industry generates much pollution and consumes a large amount of resources. Improper uses and disposal of clothing products make the problems much more severe. Fast fashion products shorten the valid lifecycle and generate more waste than regular clothing products. Considering the features of fashion products, a system of a rent-based closed-loop supply chain is developed to improve the sustainability of fashion products. The supply chain processes (fashion design and manufacturing, laundry, logistics and disposal, the operations management issues (inventory management, closed-loop logistics, human-clothing matching, booking system and the rental pricing and the sustainability promotion aspects (customization, responsive system, culture and policy aspects are investigated by devising sustainable strategies. The rationalities of the developed system and strategies are reviewed and elucidated in detail. The results may contribute to building sustainable closed-loop fashion supply chains, the related information systems and operational and managerial mechanisms.

    Full Text Available Despite the importance of the expectations and visions of the actors involved in sustainable innovations, only the societal, motivational perspective is usually considered. The fact that local actors may have different multi-motivations is typically overlooked. The aim of this study is to examine and understand the multi-motivational perspectives in a sustainable production project. First, we introduce the concept of the object and analyze the case of a biogas production project as a mediating activity for making swine production more sustainable. We argue that the object of the activity, as manifested in motivational perspectives, shapes the way in which biogas production (BP systems are implemented. The article concludes by discussing how the concept of object can be used to explore the actual and future possibilities of using artifacts for increasing the sustainability of production.

    Full Text Available Emerging sustainability challenges, such as food security, livelihood development and climate change, require innovative and experimental ways of linking science, policy and practice at all scales. This requires the development of processes that integrate diverse knowledge to generate adaptive development strategies into the future. Social learning is emerging as a promising way to make these linkages. If and how social learning approaches are being applied in practice among smallholder farming families—the bulk of the world’s food producers, requires specific attention. In this paper we use a case study approach to explore social learning among the agricultural poor. Five key evaluative factors: context assessment, inclusive design and management, facilitating learning, mobilizing knowledge and assessing outcomes, are used to analyze nine projects and programs in (or affiliated with the Consultative Group on International Agricultural Research (CGIAR. We explore three main questions: (1 in what contexts and in what ways are socially differentiated and marginalized groups enrolled in the learning process? (2 what, if any, are the additional benefits to social learning when explicitly using strategies to include socially differentiated groups? and (3 what are the benefits and trade-offs of applying these approaches for development outcomes? The findings suggest that, in the agricultural development context, social learning projects that include socially differentiated groups and create conditions for substantive two-way learning enhance the relevance and legitimacy of knowledge and governance outcomes, increasing the potential for accelerating sustainable development outcomes.

    2017-07-01

    What cognitive mechanisms account for the trajectory of speech sound development, in particular, gradually increasing accuracy during childhood? An intriguing potential contributor is statistical learning, a type of learning that has been studied frequently in infant perception but less often in child speech production. To assess the relevance of statistical learning to developing speech accuracy, we carried out a statistical learning experiment with four- and five-year-olds in which statistical learning was examined over one week. Children were familiarized with and tested on word-medial consonant sequences in novel words. There was only modest evidence for statistical learning, primarily in the first few productions of the first session. This initial learning effect nevertheless aligns with previous statistical learning research. Furthermore, the overall learning effect was similar to an estimate of weekly accuracy growth based on normative studies. The results implicate other important factors in speech sound development, particularly learning via production. Copyright © 2017 Elsevier Inc. All rights reserved.

  14. Transformative Learning for a Sustainable Future: An Exploration of Pedagogies for Change at an Alternative College

    Directory of Open Access Journals (Sweden)

    2013-12-01

    Full Text Available Educators and policy makers have long recognised the central role that education can play in creating a more sustainable and equitable world. Yet some question whether current processes across mainstream higher education prepare learners sufficiently to graduate with the capabilities or motivation to shape and create a future that is life-sustaining. This paper presents findings from a qualitative research project carried out by Plymouth University in association with Schumacher College, Devon, UK. Schumacher College is an alternative, civil society college, owned by the Dartington Hall Trust that claims to provide transformative learning opportunities within a broad context of sustainability. The study explored the nature and application of transformative learning as a pedagogical approach to advance change towards sustainability. If learners claimed transformational learning experiences, the research asked whether, and to what extent, this transformation could be attributed to the pedagogies employed at the College. The paper begins by setting out the broad background to the relationship between marginal and mainstream educational settings, and definitions and theoretical underpinnings of transformative learning, and then leads into the research design and findings. The potential for transformative pedagogies to be applied to and employed within the wider higher education (HE sector is then discussed, and the overall findings and conclusions are presented.

    2017-11-01

    In 2015, the German Federal Ministry of Education and Research (BMBF) announced that the Science Year 2015 would focus on the "City of the Future". It called for innovative projects from cities and communities in Germany dedicated to exploring future options and scenarios for sustainable development. Among the successful respondents was the city of Lüneburg, located in the north of Germany, which was awarded funding to establish a community learning project to envision a sustainable future ("City of the Future Lüneburg 2030+"). What made Lüneburg's approach unique was that the city itself initiated the project and invited a broad range of stakeholders to participate in a community learning process for sustainable development. The authors of this article use the project as a blueprint for sustainable city development. Presenting a reflexive case study, they report on the process and outcomes of the project and investigate community learning processes amongst different stakeholders as an opportunity for transformative social learning. They discuss outputs and outcomes (intended as well as unintended) in relation to the specific starting points of the project to provide a context-sensitive yet rich narrative of the case and to overcome typical criticisms of case studies in the field.

    2017-09-01

    Full Text Available This paper proposes that there is a need to prepare undergraduate design students to be responsible practitioners when they enter the workplace. The multi-faceted approach adopted by the Design School at Loughborough University to achieve this is presented. The paper outlines and reflects on the differences between the idealistic environment provided within an educational setting and the actual situation in the design industry, where there is little evidence of mainstream sustainable design practice. The paper concludes that it is valuable to provide students with a range of skills that support sustainable design thinking, even if they are not currently required by the design industry because doing so turns the students into informed individuals with the potential to lead the next generation of design practitioners.

    Ryberg, Morten; Owsianiak, Mikolaj; Hauschild, Michael Zwicky

    2015-01-01

    ? If we assess the life cycle and relate the impact scores to the remaining capacity available for impacts, there is a risk that all products are seen absolutely sustainable. In addition, how should we decide on who can use the remaining capacity? To address these issues an allocation method is proposed......Assessment of absolute sustainability within life cycle assessment (LCA) framework is operational on the country scale. However, it is difficult to apply the existing approaches to products, which are typically the scope of LCAs. How should we assess whether a chair is (absolutely) sustainable...... allocation keys specific to each product group, e.g. mass for furniture, or economic revenue for IT. The proposed method facilitates assessment of absolute sustainability of products within the LCA framework....

  16. Improving Buffalo Milk Production to Sustain the Production of Dadih by Small Farmers in West Sumatera

    Directory of Open Access Journals (Sweden)

    Wirdahayati R B

    2007-12-01

    Full Text Available The swamp buffalo which is found in many Asian regions is mainly raised for meat and draft purposes. However, in West Sumatera, it is also milked and the milk is mostly consumed as “dadih“, a well known traditional product from this area. Dadih is actually a product made from fresh buffalo milk, which is kept in bamboo tube for about 2-3 days under room temperature, without any application or addition of bacteria starter although the end product of this fermentation contains various bacteria, mould and khamir. As the natural fermented milk product, dadih is white in colour and the curd texture like tofu, tastes like yoghurt, and it is generally served as a complementing meal in some traditional occasion as well as delicacy from West Sumatera. Dadih is highly nutritive product, protein and fat contents are higher than those of yoghurt, rich in amino acids and bacteria such as Lactobacillus sp. and low in cholesterol. The raw material for dadih is limited due to the low productivity of fresh buffalo milk which is generally collected for about 0.5 – 2.0 litres/head/day. The effort in sustaining “dadih product“ is directed to the improving the management of the buffalo condition particularly those in lactating period. Feeding improvement is recommended in order to provide an adequate milk for raising its calf and to be milked for making dadih and to support the optimal reproductive activity of the buffalo dam. In future, the assessment on “dadih“ should also include the packaging improvement which can improve and prolong the storage time for the benefit of marketing purposes.
