But scientific research is much less prolific about social adhesion to those practices. How could we be certain that peasants will integrate them and transform their agriculture？ It is at that particular point that we settled our contribution. Our goal is to determine what are the levers which could be activated to promote agroecological practices, and, on the contrary, what are the obstacles which could prevent social adhesion to agroecology. The meticulous fieldwork carried in Barani, a landlocked small village in the North-West of the Burkina Faso, shows that all the ingredients for the development and the dissemination of agroecology already exist. Indeed, traditional agriculture is not so far from agroecology. But we noticed among peasants ofBarani a rejection of the local farming system synonymous, according to them, with backwardness, and an attraction for industrial agriculture, sign of modernity. Dissemination of agroecology will have to go through a major confidence-building work of the peasants with their own practices, as opposed to multiple trainings where they are always being taught what they already know.展开更多

It is argued that the mainstream approach which considers ecosystem services as an externality has many shortcomings and fails to consider institutional and political aspects---all very critical for the design and implementation of a PES （Payment for ecosystem services） project or program. The complexity and the diversity of co-evolutionary relations between ecosystem services and socioeconomic activities are spatially or territorially specific. In this sense, different types of PES market have to adapt and coevolve with different ongoing development processes.展开更多

Compared with water resources, forests and other natural ecosystems, agriculture is more vulnerable to climate change, thereby scientifically assessing agricultural vulnerability to climate change is of great significance to the formulation of rational and effective adaptation strategies. In this paper, the authors give a comprehensive review of the research from the perspective of the definition of climate change vulnerability and agricultural vulnerability to climate change, research topics, and evaluation methodologies. Existing problems in current research, including scenario application, methods, and uncertainties, are analyzed, and meanwhile, a vision of the direction for future research in assessment of agricultural vulnerability is also presented.展开更多

In China, due to the urban-rural dual structure, these changes turn out to be more complicated. Spatial restructuring are suggested as the main strategies and spatial supporting platforms for urban-rural development. However, the theory still lacks solid methodology and support from systematic empirical studies. This study seeks an adequate scientific methodology and discusses the difference of urban-rural transformation in plains and mountainous areas. A case in Shanghang County, China, demonstrates: 1) The compound ecological niche model can be a suitable approach in urban-rural restructuring, especially in mountainous areas. 2) The urban-rural development area with highly inappropriate, slightly appropriate, moderately appropriate, and highly appropriate areas are 1273.2 km2(44.69%); 906.1 km2(31.80%); 509.4 km2(17.88%); and 160.1 km2(5.62%), respectively. 3) The "deserting villages" in mountainous areas play positive synergistic roles in urbanization, in contrast to the "hollowing villages" common in plain areas. 4) The central town-village will become the most important settlement in mountainous areas. Therefore, we suggest more attention should be paid to environmental capacity in the construction of central town-villages. This study significantly extends the understanding of "hollowing village" theory and regional planning.展开更多
