Since 1901 in pre-state Israel, KKL-JNF has supported plant and soil research. Today, that support has grown into a network of research and development stations that develop cutting edge methods of farming in arid and semi-arid regions with brackish water. In addition, cheap and sustainable crop irrigation is possible thanks to the 230 water reservoirs and effluent purifying systems that KKL-JNF has built all over Israel, with the support of its friends worldwide. KKL-JNF's support of sustainable agriculture has turned Israel into a powerhouse of innovation.
