The activities of catchment management, and the implementation of catchment management plans, cannot be the responsibility of any one institution. Catchment management cuts across many sectors, geographic areas and political/administrative jurisdictions; the functions and responsibilities of catchment management are inevitably spread across several institutional structures. This section briefly outlines the legislation and key role-players in catchment management planning and implementation. Donor agencies, NGOs, and the private sector are important stakeholders, and will be identified with the catchment management planning process. This section focuses on government and legislated institutions.
