introduction: human activities have induced change and variation in world climate. climate change and variability are important issues because of their effects on agriculture, environment, public health and total society. developing countries are generally more vulnerable to the consequences of these changes, as they tend to rely more on climate-sensitive sectors, such as subsistence agricultur...

I examined agrobiodiversity in smallholder cultural landscapes with the goal of offering new insights into management and policy options for the resilience-based in situ conservation and social-ecological sustainability of local, food-producing crop types, i.e., landraces. I built a general, integrative approach to focus on both land use and livelihood functions of crop landraces in the context...

The paper use the AHP-DEA model to evaluate and analyze current situation influencing factors of rural ecological environment farmers with different livelihood strategies in 9 administrative villages 3 districts counties Three Gorges Reservoir area. conclusions are as follows: (1) deeper nonagricultural level, worse impact on environment, its status. However, degree employment is not only deter...

A survey (n=276) was carried out to gather information on goat farming systems in three districts in the Southern province of Sri Lanka. The objective was to identify the prospects and constrains to improve the economic productivity of the herds. Goats were ranked highest in population and second in terms of importance to the house hold. Buddhists were dominated in goat rearing while selling of...

It is almost certainly the case that many populations have always existed as metapopulations, leading to the conclusion that local extinctions are common and normally balanced by migrations. This conclusion has major consequences for biodiversity conservation in fragmented tropical forests and the agricultural matrices in which they are embedded. Here we make the argument that the conservation ...

Water stress in Northern China is characterized with major, inefficient irrigation water use and rapidly growing non-agricultural water demands, as well as limited water quantity and declining water quality. Water use in the region is undergoing transfer from agricultural to municipal and industrial sectors. Currently, part of the economic loss and environmental damage due to water stress can b...

The agriculture sector in the Savanna region of Togo is especially vulnerable to weather fluctuations, which have an impact on crop production levels. However, farmers’ decisions implement adaptation strategies are directly related their perceptions climate change risk. current study employed a participatory workshop and household survey 425 farmers examine drivers specific risks interest (risk...

The effects of changes in cropping production technologies, systems and input and output markets on smallholders growing tree crops for export, and the consequences on pest management strategies, including augmentative and conservation biological control, are discussed in the context of pest and crop management research, technology development and farmer training. Evolving approaches in extensi...

Irrigation water management is crucial for agricultural production and livelihood security in Morocco as in many other parts of the world. For the implementation of an effective water management knowledge about farmers’ irrigation water demand is crucial to assess demand reactions of a water pricing policy, to establish a cost-benefit analysis of water supply investments or to determine the opt...
