Paper III

Afforestation Programmes By Dr. C.M.Joy (Reader ,Sacred Heart College. Thevara, Kochi)

Periyar catchement area should be afforested to maintain summer flow in the river. A buffer zone of trees has to be established along the riverbanks. This will help the recharging of river water during summer season and also helps to attain maximum flow of water during rainy season. Survey of River Basin The entire stretch of the river should be surveyed and the boundaries are to be demarcated. Eviction of encroachers should be done. A stretch of at least 5 M on both the banks of the river should be maintained as a buffer zone of riverine vegetation.
