Bangladesh Association for Sustainable Development (BASD) is a non-government social development organization established in 1991 with the initiative of social workers, teachers, doctors and church leaders of different denominations. It is registered under Social Welfare (Dha – 03221 in 1994), NGO Affairs Bureau (886 in 1995) and Microcredit Regulatory Authority (05518-04426-00431).

Addressing human sufferings, social injustices, poverty and inequalities was the main purpose of establishing BASD by its initiators. This purpose is still relevant in the present context of Bangladesh because for various reasons about 30 percent of people of hard-to-reach areas are yet to enjoy human dignity and fullness of life.
