| Abstract: | As a special form of agroforestry, living contour hedge is effective in enhancing the sustainability of sloping land utilization, in a way that soil and water erosion is harnessed and soil quality improved. This paper discusses some principal issues in the development of the technology. Then it reviews the progress of researches on these issues, involving species choice, hedge design and management, and evaluation of ecological and economic benefits. Problems and extension limits are also discussed and the appropriate extension areas are proposed. |
