The PGGIRH of the river Zambeze, in Angolan territory, with about 150,000 km², also includes the drainage basin of the river Cuando. The main objectives of the PGGIRH are the following: Ensure water supply to the entire population, under proper conditions of quantity and quality; Prevent and mitigate the effects of floods, droughts and pollution accidents, with a view to safeguarding people and property; Ensure the availability of water for the different areas of socioeconomic activities; Recover the quality of surface water and groundwater and prevent their degradation. The scope of studies comprises four phases: Phase I - Characterisation and diagnosis of the existing situation; Phase II - Supplementary studies (hydrology and hydrogeology, water supply and sanitation, agriculture, industry, socioeconomics, energy, environment, spatial planning, hydraulic infrastructure); Phase III - Assessment of alternative scenarios; Phase IV - Strengthening of the general plan (establishment of goals and action strategies, action programmes).

In parallel with the PGGIRH, the process involved a strategic environmental assessment and community participation.

Services provided involved several fields of expertise such as: Hydrological and hydrogeological studies; water supply and sanitation; hydroelectric developments; agriculture and irrigation; water quality; terrestrial and aquatic ecosystems; environment; extraction of aggregates; spatial planning; water economy; legal and institutional aspects; strategic environmental assessment; community participation; geographic information systems.
