Description of the SLM Approach
Short description of the Approach
SWC decision makers, I.e. approach planners, lead local people to plant caragana korshinskii in the areas of serious water and/or wind erosion by means of combined inputs from government, locals and social loan etc.
Detailed description of the Approach
Aims / objectives: The most important factor that hinders agricultural development in the Loess Plateau is soil and water loss. Many measures have been taking to conserve soil and water resources. Here is one of them using caragana korshinskii as one kind of SWC vegetation approach.
Methods: With its long roots, caragana korshinskii can improve soil infiltration and extract water from deep soil layer. It can also protect soil from water and wind erosion because it is tightly fixed in the soil. It has rhizobium in its roots to improve soil fertility. Besides, its branch has economic value. To carry out this approach, planners lead local farmers to plant caragana korshinskii in the areas of the serious water and/or wind erosion. Before planting, dipping selected seeds in brine with 1% concentration, and then moving them in warm water for about 24 hours to make them easier germinating. Caragana korshinskii can be planted in holes. Autumn is the best season for seeding, but if there is much rain in Spring, it is also ok. In the first three years, young plants are very frail. They should be protected from sheep eating and cutting. After four years, the branches of caragana korshinskii above ground can be cut according to their utilization. The more you cut the better they grow.
Role of stakeholders: Besides government leaders, local land users are also the most important participants, they accomplish most of planting and maintaining work. The Research Institute is another key participant, they provide the SWC knowledge and technology.
Other important information: Caragana korshinskii has many other advantages besides ecological benefits. It has many economic values, such as supplying forage for sheep and fuel for local residents, supplying raw material for paper making, supplying green manure and improving soil quality. Finance is mainly from government, partially from loan and local input(labor).
