Users group brings villagers closure How can they be sustained / enhanced? Manageent group to be reorganised annuly

Strengths/ advantages/ opportunities in the compiler’s or other key resource person’s view
Water scarcity of the area partly solved How can they be sustained / enhanced? Regular desilting shound be done.
Heavy sand casting and soil loss controled How can they be sustained / enhanced? More vegetative cover required for catchement area
