Grassroots organizations (GROs): Third World membership organizations that work to improve and develop their own communities. Also called people's organizations or base groups. There are three major types of GROs in most countries. Local Development Associations (LDAs) such as village councils or neighborhood associations work on many development issues that concern the entire community. Interest Associations are more limited in membership, and tend to work on particular issues. Among the examples are women's groups and water users' associations. Pre-cooperatives, cooperatives, and other community-based enterprises are a third type of GRO, distinguishable from other for profit organizations by their broad based ownership and participation in wider community development activities.
Local organizations: A broader term including GROs, as well as other membership organizations such as burial societies and kinship groups.
GRO networks: Horizontal linkages among GROs, regionally based.
Grassroots support organizations (GRSOs): Nationally or regionally based development assistance organizations, usually composed of paid professionals that work with GROs in communities other than their own. Also called intermediary NGOs, nongovernmental development organizations ( NGDOs), voluntary development organizations ( VDOs), etc. GRSOs are nonprofit organizations, that may or may not have members.
