2.1 Descrição curta da tecnologia

Definição da tecnologia:

Soil bund and Fanya Juu constructed along the contour lines in microwatershed to conserve soil moisture and control erosion.

2.2 Descrição detalhada da tecnologia

Descrição:

Soil bund and Fanya Juu constructed in combination in a microwatershed for retaining maximum possible rain water in the soil by obstructing runoff water. Soil bunds are suitable for steeper slopes compared to fanya juu terraces which are more effective in gentle and flatter slopes.Land users in the SWC area prefer to combine the two physical structures for many reasons.One important factor is the cost of establishment, which is a function of labour needed for the construction. Fanya juu which means throwing soil upslope in Kiswahili intails throwing soil upslope which is more labours than throwing soil to downslope in the case of soil bunds. The other reason is that cultivated lands with fanya juu terraces are not easily accessed by free grazing livestock. The ditches placed in the downslope side of the embankment (fanya juu) is not easily vrossable but in soil bund although not that easy livestock are seen to trample over the embankment and jump the ditch which is placed in the upslope side. The other advantage farmers consider is that Fanya juu is more efficient in controlling runoff because the water that overtops the embankment is trapped by the ditch. Fanya Juu despite its high cost is preferred to be applied in combination with bunds because of the other advantage that it forms bench terrace rapidly.

Purpose of the Technology: The major purpose is to trap as much rain water as possible and also control soil erosion. Cultivated lands with with Soil bund and Fanya Juu have shown remarkable improvement in soil moistureavailability to crops compared to fields with no measures.

Establishment / maintenance activities and inputs: Soil bund and Fanya Juu are established in the same way by digging soil from and embanking it on a contour line. A contour line is laid out by following zero gradient. Once the soil is dug and embanked it is lightly compacted to avoid colapse. To further ensure bund stabilityuseful trees/shrubs are planted.The planted tree/shrub species are those offering multiuses such as fodder, fertility improving and fuelwood. Maintenance: It is done by repairing breaks and managing planted trees on the structure or by upgrading the structure by increasing its height and plant improved tree and fruit tree species.

Natural / human environment: The technology is suitable to semiarid climatic condition which have erratic rains and where crop production is limited by soil moisture stress. Soils in the technology area are susceptable to erosion and therefore the structure should be stablized by planting trees or grass species.
