The desert is a unique ecosystem, not normally characterized by forests. How, then, did KKL-JNF achieve the stunning feat of 40,000 acres (16,000 hectares) of desert afforestation to date?
This is due to the afforestation methods developed by KKL-JNF for the desert; savannization – planting single trees or clusters of trees in areas where climatic conditions do not permit woodlands or shrubs to grow without substantial human intervention.
Their growth relies on advanced water harvesting techniques that capture runoff rainwater in ridges, depressions, terraces and limans (tree clusters planted in reinforced water catchment basins). Savannization has an added value to it as well: the trees slow down soil erosion, one of the biggest environmental problems in the Negev.
