The Department of Social Development Services (DSDS) was established in 1983, at the same time the Institute of Human Ecology was elevated to a College.

The DSDS views development in the context of ecology as a social transactions. Thus, its programs focus on the development of social organizations (human and community interest groups) and institutions (political, economic, educational and religious).

Social organizations and institutions provide the venues for transacting ecologically-oriented social development. It is through social transaction that people must coordinate diverse capabilities and activities for sustainable development.

Hence, the mission of the DSDS is to develop or strengthen the capability of social organizations and institutions to actively participate in organizing, mobilizing and managing human and environmental resources in promoting economic productivity, social development and ecological well-being.
