| Public authorities and consumers increasingly support food value chains that are more environmentally friendly. However, these value chains are faced with technical, economic and institutional limitations, calling into question their long-term viability. Based on two case studies of alternative food chains in France, namely einkorn (Triticum monococcum) in Haute Provence and organic rice in the Camargue, we evaluated their capacity to remain both viable and environmentally, economically and socially sustainable. After assessing the traditional economic, social and environmental performance of their sustainability, we performed a network analysis to determine the survivability of the systems. The combined use of the traditional pillars of sustainability and... |

| Organic farming is a rapidly growing sector both in Croatia and elsewhere. However, there is some concern as to what a widespread adoption of organic farming would bring to society as a whole. The costs and benefits of this development and the associated trade-offs are largely unknown and have hardly been explored. There is a vast body of evidence showing that organic farming in most cases environmentally outperforms non-organic systems. However, organic farming is associated with lower yields and its further expansion might lead to job losses in some other sectors and potentially jeopardise the overall economic strength of a country. This research presents an attempt to assess the environmental and economic consequences of the large-scale adoption of... |

| Habitat fragmentation, the process by which relatively continuous habitats is broken into smaller pieces, occurs in natural systems but is to a high degree also human-induced through landscape use. Fragmentation of the landscape produces a series of habitat patches surrounded by a matrix of different habitats and land use regimes. The major landscape consequences of fragmentation are loss of habitat, reduction in habitat patch size, and increasing isolation of habitat patches. In general, population performance declines in response to habitat loss but size of remaining area and isolation effects is known also to influence the population trend. Small mammals are well suited for examination of population responses to habitat fragmentation as they have... |

| The rapid development of the economy has created an increasing demand for energy in China. The limited resources of fossil energy are a risk for the development of China. Sustainable agriculture like organic farming (Green AAA in China) with biomass energy - as done in developed countries like Germany - is an option to reduce these risks. In China, agriculture is not energy efficient, and the intensive farming is not sustainable. The scientific challenge is to develop sustainable farming systems which can fulfill national food security, food safety and considerable renewable energy production without harming the environment, and are acceptable to the people and the economy. The protection and intelligent utilization of resources is the core of rural... |

| Agro-ecological Service Crops (ASC) are introduced in the agro-ecosystems to provide or enhance ecological services, thus promoting the whole soil-plant system equilibrium. ASC introduction and proper management have impact on soil quality and fertility and soil nutrients losses. They also contribute to increase soil C sink potential, to mitigate GHG emissions and influence weeds, diseases and pests occurrence. To avoid competition with the subsequent cash crops, the growth of the interposed ASC is terminated in advance of the cash crop planting. The traditional, most widespread, technique used to terminate the ASC is incorporation as green manure into the soil by tillage. However, since tillage is an energy and labour consuming and soil disturbing... |

| Urban sprawl and population growth lead to loss of contact with nature for urban residents; thus giving more importance to the remaining urban green spaces for the residents’ well-being. In this study, weassess the preferences and uses of urban and peri-urban green spaces by inhabitants of the city center andof the bordering areas of the pre-alpine city of Bellinzona in southern Switzerland. In a quantitative surveyin which a questionnaire was mailed to a selective quota of 1000 local households, we asked about generalperceptions of the quality of life; the general importance of the green on the surrounding mountain slopes; the frequency of urban and peri-urban green space visitation including the activities undertaken in them;and the motivations for... |

| North European landscapes are highly dominated by agriculture, where small biotopes, e.g. meadows, uncultivated grassland, hedge rows, field boundaries, surroundings of water ponds, only comprise a low percentage. In recent years organic farming has expanded in acreage due to customers increased awareness regarding pesticide and fertilizer use and biodiversity conservation. However, organic farming has changed from an extensive production with small fields, low mechanical impact and high crop diversity towards larger fields, intensive mechanical treatment, lower weed densities and lower field diversity. Still, organic farms could play an important, role in the agricultural landscape as refuges for some small mammal species. We studied the responses of... |

| Birch tar oil (BTO) is a by-product of processing birch wood in a pyrolysis system. Accumulating evidence suggests the suitability of BTO as a biocide or repellent in terrestrial environments for the control of weeds, insects, molluscs and rodents. Once applied as biocide, BTO may end up, either through run-off or leaching, in aquatic systems and may have adverse effects on non-target organisms. As very little is known about the toxicity of BTO to aquatic organisms, the present study investigated acute toxicity (LC50/EC50) of BTO for eight aquatic organisms. Bioassays with the Asellus aquaticus (crustacean), Lumbriculus variegatus (oligochaeta worm), Daphnia magna (crustacean), Lymnea sp. (mollusc), Lemna minor (vascular plant), Danio rerio (fish),... |

| The aim of the paper is to present results from a review of successful mid-scale organic values-based chains, where characteristics of such chains and their strategies for growth are in focus. The work is part of an EU-project, Healthy Growth, where ten European countries participate. Results are based on reviewed research in each participating country and a general review of research on successful chains. Results show that successful mid-scale values-based chains are characterized by an emphasis on diverse values and product qualities, they emphasize personal relationships between chain actors, are based on a diversity of consciously chosen sale channels both direct and indirect and utilize a variety of communication channels/means to communicate values... |

| Farmers in the mid-hills of Nepal follow diverse farming systems. The peri-urban area of this region, where population density is higher, faces several problems in farming. While hills suffer from erosion because they are erodible, the peri-urban areas face the problem of decline in factor productivity, particularly in intensively cultivated farmlands. The present study is concerned with simulating farm income on a regional scale based on soil management practices. Spatial explicit simulation shows that the loss of farm income due to degradation is substantially higher in hills while it is lower in valley bottoms. Strategy formulation and testing in the spatial environment indicates that Geographic Information System is an appropriate methodological tool... |

| Neste trabalho, são apresentadas ações da primeira fase do projeto “Tarumã Vivo” desenvolvido pela Embrapa Amazônia Ocidental no Assentamento Tarumã-Mirim (Manaus-AM) e parceiros, com o objetivo de gerar conhecimentos e ações sustentáveis de forma colaborativa com os agricultores familiares. Os diagnósticos mostraram que a retirada da floresta está relacionada à produção de carvão vegetal e lenha, exploração de madeira e agropecuária. O projeto considerou o manejo da paisagem agrícola e os aspectos sócio-econômicos, o que resultou na construção de alternativas diferentes em objetivos, superfície, composição, arranjo e manejo, em 29 propriedades agrícolas. Os cursos ministrados foram meios importantes para mudanças, pois viabilizaram a substituição da venda... |

| Efficient utilization of biomass is hindered by the recalcitrance to dissolution of semicrystalline cellulose. Pretreatment is often used to alter the structure of cellulosic biomass in order to make cellulose more accessible to solvents and enzymes. The pretreatment involves physical and/or chemical processing which affects the degree of crystallinity and size of biomass particles. We examine here the effects of (i) solvent properties, pretreatment steps and temperature, and (ii) fiber diameter and degree of crystallinity, on the kinetics of cellulose swelling and dissolution. To this end we have combined (a) experimental results on cotton fiber swelling, change in crystallinity and dissolved amount when treated under different solvent conditions, with... |

| This paper explores the potential of Actor Network Theory (ANT) in understanding how the process of interaction and translation between human and non-human actors contribute to the development, adoption and diffusion of science-based innovations linked to the transition to organic farming. The study relies on two case studies, the French Camargue case covering a range of technical and social innovations, and the case from Bulgaria focusing on the development of a technical and product innovation, i.e. a veterinary product for organic beekeeping. The paper shows the limitations of classical approaches in studying innovations since they underestimate the role of heterogeneous actors, their status, and how they interact with each other. We argue that focusing... |

| Is low greenhouse gas emission (GHG) agriculture possible? Is it, in fact, desirable? In seeking answers to these two basic but extremely relevant questions, this study examines current farming practices, and incorporates scientific databases from longterm field experiments as case studies for low GHG agriculture. Further, the study examines the changes that will be needed for low greenhouse gas agriculture systems to become a reality. It also elucidates the adaptive capacity of agro-ecological farming system approaches, using organic system case studies from the scientific literature. Each year, agriculture emits 10 to 12 percent of the total estimated GHG emissions, some 5.1 to 6.1 Gt CO2 equivalents per year. Smith, et al. (2007) and Bellarby, et al.... |
