2.1 技术简介

技术定义:

Piling of stones and rocks along the contour to control run-off and soil erosion. It is also about the creation of small basins by removing stones and using them as barriers.

2.2 技术的详细说明

说明:

This is a low-cost erosion control technology by piling stones/rocks along the contour. The spacing of the piles depends on the slope and the availability/abundance of surface rocks. The stone bunds, usually 0.4 meter wide is intended to slow down run-off and catch/impound soil that moves downslope, etiher by water or by gravity. The technology is also about the creation of small basins by removing rocks and using them as barrier. In these small basins, water is impounded and allow to infiltrate. Soil carried with the run-off is deposited in these basins for the raising of high value crops. The technology is most especially applicable in areas where limestone and other rock outcrops and where the soil is commonly shallow and skeletal. With time, natural terraces can form. Limestone/rock outcrops are also used in the construction of check dams along small waterways. These check dams will result in the formation of flat-bottom valleys where transplanted rice is usually grown. Series of check dams will form terraces along valley floor in the long run.
