Short supply chains have existed in France for a long time, however, new and different forms have recently emerged delivered by new actors who are looking beyond the simple economic dimensions of local food. In particular, it is obvious that short supply chains have the potential to work as an...

Sustainability assessment oriented to improve current systems and practices is urgently needed, particularly in the context of small farmer natural resource management systems (NRMS). Unfortunately, social-ecological systems (SES) theory, sustainability evaluation frameworks, and assessment methods are still foreign not only to farmers but to many researchers, students, NGOs, policy makers/operators,...

The Green Revolution, the symbol of agricultural intensification not only failed to ensure safe and abundant food production for all people, but it was launched under the assumptions that abundant water and cheap energy to fuel modern agriculture would always be available and that climate would be stable and not...

Cocoa cultivation is generally considered to foster deforestation. Contrary to this view, in the forest–savannah interface area in Cameroon, farmers have planted cocoa agroforestry systems on Imperata cylindrica grasslands, a soil-climate zone generally considered unsuitable for cocoa cultivation. We undertook a survey to understand the agricultural and ecological bases of this innovation....

There are traditional and indigenous agricultural systems which contain Agricultural Biodiversity of Global Significance (ABGS). In the proposed project, we will apply the CBD definition of agricultural biodiversity. Building on articles 8j and 10c of the CBD, which recognise the importance of indigenous and traditional practices for the maintenance of...

Although there are well-established concerns about climate change effects in northern Ethiopia, there is little quantitative information concerning how serious these effects are to small holder farming. Moreover, studies on farm level adaptations that farmers make to minimise the potential impacts of climate change are lacking. Both quantitative and qualitative...

Agriculture plays a key role in the economic and social development of Georgia. Though over half of the active population works in this sector, it makes up only 17% of the GDP. The rural population has not benefited from the economic growth of recent years and is as a result...

The Green Revolution not only failed to ensure safe and abundant food production for all people, but it was launched under the assumptions that abundant water and cheap energy to fuel modern agriculture would always be available and that climate would be stable and not change. In some of the...

本文综述了我国农业生态学的发展过程与演化特点, 并站在国际视野上分析了现代农业生态学发展趋势, 着重提出农业生态学正从宏观与微观两个层面不断拓展, 并把研究引向深入。从宏观层次上讲, 农业生态学正从已往的宏观农业生物学层面逐步深入到“三农”的社会学层面, 研究水平从以往关注农业生态系统结构与功能的关系逐步发展到人们普遍关心的食物系统(food system), 即从生态经济学角度研究农业生态系统能物流形成与运转对经济社会发展的影响以及社会政策法规对食物系统的调控作用。也就是说, 现代农业生态学越来越重视人类社会生态觉醒对保护农业生态系统环境, 促进无污染生产及市场营销的重要作用。因此, 在当代西方国家, 许多农业生态学工作者十分重视通过各种社区运动(movement)或行动(action)来促进政府、生产部门、销售部门以及相关管理部门接受农业生态学思想, 自觉按照生态规律办事, 保证食物生产系统健康高效运行, 这已成为现代农业生态学教学科研和生产实践的重要内容, 涉及科学理论研究-实验示范推广-各种联盟运动推进-社会公众自觉参与等全过程, 体现了现代农业生态学的时代特征。从微观层次上讲, 现代农业生态学正进入农业分子生态学时代, 它借助现代生物学的发展成就, 运用系统生物学的理论与技术, 深入研究农业生态系统结构与功能的关系及其分子生态学机制。特别是随着现代生物技术的不断完善, 环境(宏)基因组学、蛋白组学技术的问世, 极大地推进了人们对未知生物世界的认知, 尤其是对生物多样性和基因多样性的深层次剖析, 使得农业生态学能从分子水平上深入研究系统演化的过程与机制, 促进从定性半定量描述向定量和机理性研究推进。客观上要求农业生态学工作者必须与时俱进, 不断完善自己的知识结构, 提高现代科学研究技能, 只有这样才能自觉接受新的科学知识, 促进传统科学向现代科学提升。本文特以例证分析了这一科学发展的必须性和重要性, 旨在引发广大同行的反思与共鸣。

Health, freedom and social justice cannot be separated. Anyone who loves a neighborhood, a nation or a small planet enough to work for its future, inevitably measures success by its health and well-being. How long do the neighbors live, and with what degree of freedom from the burden of illness?...

Dans les zones de savane subhumides d'Afrique de l'Ouest et du Centre, le modèle de production agricole inspiré par la révolution verte reste celui proposé aux agriculteurs et aux éleveurs. Il mobilise des intrants chimiques, des équipements et des races et variétés sélectionnées. Cette option a été confirmée après les...

The aim of the study is to assess the food security, adapting/mitigation opportunities to climate change and policy situation and draw policy recommendations. The study was conducted in some selected districts of Tigray Region, Ethiopia based on some exemplary interventions such as communities, ISD, BPA and PROLINNOVA-Ethiopia. Agriculture in tropical...

Large, decimated ecosystems can be restored. Bringing large areas back from environmental ruin is possible, and the results are key to stabilizing the earth's climate, eradicating poverty and making sustainable agriculture a reality. Under the guidance of a few people who have knowledge and vision, local uneducated rural poor can...

Vivimos en un país que tiene particularidades culturales, demográficas, geográficas y ecológicas muy singulares; un territorio con poca disponibilidad de tierra para la agricultura y con grandes desafíos para ampliar la frontera agrícola. Sin embargo, su perfil y clima le confieren un alto potencial para cultivar productos con extraordinarias características de sabor, aroma, textura, y cosechados en momentos en que...

Once the scene of devastating droughts in 1984, a few visionaries in Ethiopia have used Agroecological Natural Technology Solutions and Permaculture Design principles to begin bringing areas of arid land back to productivity and ecological balance.

Two dairy production systems with biggest share in total milk production in Central Serbia are small farms with tie stall barn and small farms with grazing period. In the article are examined their main system characteristics, sustainability and integration in dairy supply chain. Three dimension of sustainability were explored by...

L'auteur analyse comment dans les zones de savane subhumides d'Afrique de l'Ouest et du Centre, le modèle de production agricole inspiré par la révolution verte reste celui proposé aux agriculteurs et aux éleveurs. et que bien que connus des structures de développement agricole les modèle de production"agroécologiques" ont rarement été...

The Food and Agriculture Organization (FAO) of the United Nations defines Globally Important Agricultural Heritage Systems (GIAHS) as "remarkable land use systems and landscapes which are rich in globally significant biological diversity evolving from the co-adaptation of a community with its environment and its needs and aspirations for sustainable development"....

Smallholder farmers in semi-arid Africa are in an increasingly vulnerable position due to the direct and indirect effects of climate change, demographic pressure and resource degradation. Conservation agriculture (CA) is promoted as an alternative to restore soil productivity through increased water and nutrient use efficiencies in these regions. However, adoption...
