Environmental Degradation and Dryland Agro-Technologies in Northwest China

Environmental Degradation and Dryland Agro-Technologies in Northwest China"e; is a documentation of past and present research, training and extension experiences on: environmental degradation; conservation farming systems; water and nutrient management options; soil and water management technologies and training; soil erosion control; dryland agriculture and soil erosion; soil fertility and crop production; drought and soil water use, demonstration of ecologically sustainable agriculture; and dissemination of farming system technologies in the arid and semi-arid lands of Northwest China. These concerns are expounded on both from the national (China) and Regional (Loess Plateau) perspectives. The information provided herein was obtained through a review of all relevant literature and firsthand consultations/discussions undertaken by the author with professors and local research scientists, technicians and farmers in Northwest China. The facts and figures presented are based on their experiences of many years. This publication does provide valuable scientific information on the status of environmental degradation and dryland agro-technologies within Northwest China that are either traditional or newly developed through scientific research at various relevant Institutions such as NWAU, NWISWC and Regional Academies of Agricultural Sciences such as SAAS, GAAS, NAAF and QAAF. There are lessons to be learnt and plausible remedial conservation measures to be adopted elsewhere from these experiences in Northwest China.
