The UNESCO Co-Action Programme provides aid to a number of projects in developing countries, conceived and carried out by local leaders at the community level. Generally the projects are submitted either through national commissions for UNESCO or through international non-governmental organizations. Priority is given to projects in the least developed countries and to those aimed at the most disadvantaged groups: women, the physically disabled and refugees. Each year about 75 projects on the average receive financial assistance from the Co-Action Programme thanks to voluntary contributions. The Programme provides liaison between projects and donors for whatever period is required.
