Transboundary: Junction of land degradation, biodiversity loss and water resources management in Kagera and Nyando catchments of Lake Victoria basin (#384)

The Lake Victoria Basin is facing major ecological challenges stemming from unsustainable agriculture practices and deforestation, impacting the livelihoods of the local communities. Actions have been taken, including an action plan for management of the basin and the establishment of Lake Victoria Basin Commission, responsible for management initiatives. This case study provides insights into the link between policy formulation and implementation and enforcement. Especially, it demonstrates the importance of rooting the policies within the local communities.


Over the last 50 years the Lake Victoria and its watersheds have undergone rapid ecological changes. Currently, major environmental threats in the Lake Victoria Basin (LVB) include unsustainable agriculture and deforestation in the catchments. 

This has resulted to sedimentation and proliferation of aquatic plants in the lake, most notably phytoplankton and an increase in water hyacinth mainly originating from the Kagera river basin.

The threats facing the lake have caused considerable hardship for the population depending on it for their livelihoods and have also reduced the biodiversity of the lake’s fauna and flora. More than 80% of the population in LVB is engaged in agricultural production and the basin forms a significant part for agriculture and livestock keeping that maintain the livelihoods of small-scale farmers. Deforestation coupled with bad agricultural practices has exacerbated the problem of sedimentation in the lake. As a result, soil erosion in prime agricultural areas within the catchments causes food productivity losses.

In Kagera and Nyando catchments there is also persistent land degradation accompanied by serious loss of biodiversity with impacts on the agro-ecosystems thus affecting the livelihoods of local people who largely depend upon the natural resources for their living.

As the main contributor of water inflow into Lake Victoria, the Kagera River is a major source of sediment and phosphorus flow into Lake Victoria. Of the eleven main rivers draining into Lake Victoria from Kenya, the Nyando river basin has the highest average slope and sediment transport capacity. Floods in the Kano plain have become more severe and frequent as the river gradually losses its ability to buffer environmental variability.

Actions taken

The riparian countries of LVB through the East African Community (EAC) and its protocol for sustainable management of the LVB have developed an action plan for management of the entire lake and its catchments across sectors.

In 2003, the EAC signed a Protocol for Sustainable Development of LVB. The Protocol has played a crucial role in the establishment of an institutional framework for better management of the LVB. Under the protocol, Lake Victoria Basin Commission (LVBC) was formed as an apex institution responsible for all the management initiatives in the LVB.

Other important management bodies involved in the LVB include Nile Basin Initiative (NBI) and the Nile Equatorial Lakes Subsidiary Action Programme (NELSAP) focusing on the promotion of economic growth, eradication of poverty and a reversal of environmental degradation.

This case study provides an insight into watershed management in the Kagera and Nyando catchments by illustrating the link between policy formulation and actual implementation and enforcement.

Lessons learned

  • Policy framework and formation of institutions in LVB was driven by the EAC and a new institutional framework under the LVBC has provided a platform for coordination and the formation of strategies for catchment management. However, the coordination and exchange of information is mainly at top levels.
  • There is a clear relationship between poverty and environmental degradation reflected by the inability to adopt and undertake conservation measures by majority of the people. Most people in the basin are struggling for basic needs of life and the thought of conservation is far from obtaining those needs.
  • Although significant progress has been made in formulating land management policies and the promotion of land management practices, their practical application at subsistence level still remains low. This is due to inadequate extension services to reach the small scale farmers much remains to be done for scaling up and translating the policies into concrete actions at the micro watershed level.
  • Formation of village watershed committees is crucial to act as mediators among stakeholders, especially local communities within a catchment and the government agencies at district level. It makes the management plans well rooted in the local communities in a catchment. Involvement of local communities through watershed committees also enables the use of local knowledge and resources in developing cost-effective plans and to increase the acceptability of these plans among stakeholders.
  • Use of incentives creates a more positive attitude to conservation among framers and pastoralists and helps accelerate conservation. Application and wide adoption of incentives in the catchments helps to encourage subsistence famers to take conversation measures which in turn prevents land degradation in the basin.
