A low cost and an easy activity for protecting agricultural lands, gardens and public infrastructure from the damages of flash flood. The plantation of long root trees in lower catchment areas is to hold the soil in place with their root structures, decreasing land degradation and soil erosion. Cuttings of willow and poplar also serve as wind breaks. Protection by fencing with barbed wire in two first years also prevents grazing of leaves and new branches by animals.
Additional benefits of the technology are the increased availability of wood beams for construction, of fuel wood and of fodder. Increasing the number of indigenous trees helps to reduce the negative effects of climate change.
