2.1 Short description of the Technology

Definition of the Technology:

Platforms created in series along the slopes, separated by punch of stone, vertical, reduced the length of slopes and facilitating the infiltration of water and increasing production

2.2 Detailed description of the Technology

Description:

The terraces, platforms are created on the slopes, where the slope exceeds 30, to reduce or eliminate the gradient of the slope, creating an agricultural field with better soil fertility. Such platforms have 5% inclination to the inside retaining more water to its surface, and 1% of the drainage along facit, in case of saturation of soil in water. The separation between two platforms is performed by punches from the local stone, that structure has to be calculated, taking into cosideração the slope of the slope, the width of the platform, edefoclimáticas conditions and other variables.

Its primary objective is to adapt the land to use it intends to take to eliminate the slope of the hill, working to increase soil moisture, the reduction of runoff, and its kinetic energy through the punches

Implementation: Need wide availability of labor and large technical training for its implementation. The activity of implementation requires the calculation of the volume of soil to be moved, thus defining the width of the platform, this volume that depends crucially on the thickness of surface horizon soil. In some regions where there are avenues of access to machines, the platform is done by tractors, others are made by hand. The construction of the punch, requiring stone and labor requires high technical capacity in both dimensions of the foundation as part of the whole structure.

Natural / human environment: Built in soils of agricultural vocation of medium texture, mostly in areas of regadioem that the irrigation system requires that the area is flat, sub-humid areas and semi-arid. Hillsides with slopes greater than 20%

It is a measure purely structural: Great movement of earth, made with hand tools and / or machines. The production in these areas is subsistence or mixed. This measure is carried out mainly in areas where the land user is owner

3.7 Main types of land degradation addressed by the Technology

Comments:

Main causes of degradation: soil management (It is cultivated maize and peanuts on land slopes very pronounced and boot), crop management (annual, perennial, tree/shrub) (At the end of each cycle of cultivation of maize, the most prevalent, the crop residues are deracinate, leading to the loss of soil cover), droughts (ocorrem secas cíclicas nesse país, sendo a mais marcante, a de 1947)

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), disturbance of water cycle (infiltration / runoff) (A fraca cobertura vegetal não favorece a infiltração da água quando chove, principalmenThe low vegetation cover, does not favor the infiltration of water when it rains, especially where there are crus), Heavy / extreme rainfall (intensity/amounts) (Sometimes heavy intensity rains that occur associated with poor vegetation cover and increase soil erosion)
