Résumé partiel
China has been experiencing rapid transitions during the fast process of development since XiaoPing DENG launched economic reform in 1978. However, after 30 years of development, China is being challenged by two typical problems : one is the concentration of the remaining rural poverty in some areas, which are identified as less developed areas ; and the other is the degradation of environment. These two problems are more serious in the northwest than in other areas since the northwest is the droughtiest inland area in China. Both the incidence of rural poverty and the incidence of rural low-income are much higher in the northwest than in other areas of China. For China, the increasing income gap among regions is a profound social problem. Meanwhile, water scarcity is the cause of ecological deterioration and desertification of farmlands. All of the problems reported above have a close relationship with agricultural development. In this less developed area, agriculture is still the main source of income for most farmers. However, this sector consumes almost 90% of the total water resources ; thus, its water consumption is the main obstacle to sustainable development. The patterns of agricultural development with limited water resources that can reduce rural poverty and halt desertification of arable lands must be identified and studied. In other words, the sustainable agricultural development in the northwest has to meet three conditions simultaneously : improving or maintaining farm income, reducing water consumption to a low level, and preventing the abandonment of arable lands. Therefore, the objective of this study is to identify patterns of sustainable agricultural development with limited water consumption in the droughty northwest. In order to achieve this objective, this study is divided into three parts : (1) the role of irrigation in rural poverty reduction ; (2) the role of irrigation in primary crop production and improvement of technical efficiencies ; (3) limitation of water consumption and implementation of sustainable agricultural practices.
