Watershed Development Management (WDM) Programme has given PDS new enlightenment. The Society holds the distinction of introducing the concept in this part of the country in early 90’s with the help of EEC. The years that followed saw PDS becoming an authentic body in watershed management and related activities. As far as WDM is concerned, the Society assumes the roles of promoter, programme implementing agency, support voluntary organization and resource centre. It is one of the Support Voluntary Organizations (SVO) of Council for Advancement of People’s Action and Rural Technology (CAPART) for the promotion of its watershed development programme in the South Indian States of Kerala, Tamil Nadu, Andhra Pradesh, Karnataka and the Union Territory of Pondichery. These programmes have produced great impacts in the conservation of land, water and biomass.
Integrated Rural Technology Centre (IRTC) under Kerala Sasthra Sahithya Parishad (KSSP), an active NGO in Kerala, was surrounded by various useful trees. The center provides various extension and training courses for local people, not only in agricultural field but also in rural industrial and development fields such as soap making, biomass gas, and panchayath resource mapping. As promoted by many NGOs including this institute and PDS in the following, vermiculture or vermicomposting seems to be getting popular among farmers in India and other tropical countries. This might be applied in agroforestry systems and organic farming
