We cite sources on this site because an environmental claim without one is just an assertion in a nice typeface.
Key sources
- Peer-reviewed, 2021
Trace metal concentrations in the River Rwizi ecosystem
Measures heavy metals in the abiotic and biotic components of the system and assesses human health risk. The strongest available evidence on contamination. Published in Heliyon.
- Government
Rwizi catchment management plans
Ministry of Water and Environment. Authoritative on catchment boundaries, land cover proportions and management zoning. The source for the ~8,000 km² basin figure.
- Reference
Hydrological records at Mbarara
Discharge figures: 25.4 m³/s mean, 16.5 minimum, 35.7 maximum. Useful for flow context, not for trend analysis without the full series.
- NGO reporting
ACODE and partner catchment restoration reporting
Documents mapped hectares, restored kilometres, bamboo buffer planting and wetland restoration at Kakigaani. Good on what has been attempted; treat self-reported figures as self-reported.
- Press
Ugandan press reporting, 2018 onwards
Daily Monitor and New Vision have covered the river extensively. Valuable for the human account and for tracking political attention. Figures vary between reports.
- International
Ramsar site descriptions
Official descriptions of the Lake Mburo–Nakivali Wetland System and Sango Bay Wetland Forests, both connected to the Rwizi drainage.
Where the sources disagree
Catchment area, river length and the number of dependent people all vary between sources. We give ranges rather than picking a number, and we say which definition we are using. If you find us being inconsistent, tell us and we will fix it.
Our own data
Our quarterly monitoring records, fixed-point photographs and planting survival counts are available to researchers on request. They are a small dataset from a small programme and we describe them that way.
We ask two things in return: tell us what you find, including if it contradicts something we have published, and cite the data properly so that others can trace it.
Requesting data or collaborating
We would rather our monitoring records were used by someone with better analytical capacity than ours than sat unexamined on our own shelf.
