2.1 Short description of the Technology

Definition of the Technology:

Vegetative measure based on the planting of the bush, Leucaena leucocephala, on line along the level curves in the steep slopes

2.2 Detailed description of the Technology

Description:

The technique consists of planting rows of Leucaena leucocephala in the level curves along the slopes. This legume has high rate of reproduction and the permanence of their seeds in the soil can reach 10 years before germination. It is very resistant to fire and to pruning. Can reach 4m in height and if not controlled, can invade a field of culture. The plant has great potential for feeding of livestock (protein (21-26% DM), fiber (15-25% of crude cellulose MS) vary depending on the age of the plant)

Purpose of the Technology: The planting in curves level is to achieve the stabilization and restoration of degraded soil. The technique reduces the runoff, retain sediment, solid, incorporates greater quantity of organic matter in the soil, promotes infiltration and covering the soil with vegetation.

Establishment / maintenance activities and inputs: Its installation requires a medium level of technical knowledge to marking the curves level where it will install. Planting is done in a simple way of transplanting a plant nursery to the ground. It is easy to spread a culture, its management after the fruit must be rigorous, ensuring that the fields become invasive. The early harvest fruit is an option to take into consideration when implementing this technique. The bar between the plant is 1m and the distance between the bands is associated with 5m.Sometimes it is ssociated with olds small punch to rehabilitating that structure.

Natural / human environment: The top of the slopes where they practice pluvial agriculture is more susceptible to soil erosion because of its steep slopes and the inappropriate cultivation techniques carried out there, is the area of higher prevalence of this technique. The production of Leucaena is used both for animal feed as a source for energy (firewood).

3.7 Main types of land degradation addressed by the Technology

Comments:

Main causes of degradation: soil management (It is cultivated corn and peanuts on land slopes very pronounced and boot up the plants by the root in end of the cycle), disturbance of water cycle (infiltration / runoff) (There are many crusts exposed, because of loss of soil, reducing infiltration of water), poverty / wealth (Leads sensitized peoples to advocate action against the landscape for survival of the family), education, access to knowledge and support services (Knowledge and technical training increase the options for means of survival of the community that acts on the forest, the degree of attending school is low and the illiteracy rate is 17%)

Secondary causes of degradation: overgrazing (Creation of the wild animals compact the soil, destroying the structures for the conservation of soil and water exists, and creates conflict), Heavy / extreme rainfall (intensity/amounts) (Sometimes heavy rains (intensity) that occur associated with poor vegetation cover, increase soil erosion), governance / institutional (Lack of applicability of the laws that manage the land)
