N2  - Yellow River Basin (YRB) is the cradle of Chinese civilization. Agriculture production plays a very important role in regional food security. Currently, soil erosion, poverty and water shortages are three major problems that affect the development of agriculture in YRB. Severe soil erosion is leading to loss of fertile topsoil and decreasing soil productivity. These processes are particularly evident in dry and sloping lands associated with rainfed agriculture. How to face and resolve these problems in agriculture? And what are the key techniques to improve rainwater use efficiency? According to the results in the drylands conservation agriculture research and practice, CA is the most promising approach for sustainable development in agriculture, such as harvesting of rainwater using residue mulches, which can increase crop production, and the reduction of soil tillage and construction of water harvesting and supplementary irrigation system. Not only does it generate immediate benefits in terms of increased farm productivity, it also offers social benefits of great relevance to YRB
