More than 50% of the country's GDP comes from the rural sector. Development of this sector is thus crucial for national development. The Rural Development and Cooperatives Division of the Government is responsible for planning implementation, monitoring and evaluation of rural development programs. Bangladesh Rural Development Board (BROB), the Department of Cooperatives and the Academies for Rural Development at Comilla and Bogra play important roles in environmental efforts for rural development. Major functions of the rural development agencies include employment and income generation, provision of credit and institutional support to rural target groups, vulnerable group development, formation of rural cooperatives, provision of health care, sanitation, safe drinking water, education etc. Alongside the public sector, the NGOs specially Grameen Bank and BRAC play a key-role in rural development efforts.
