Modeling large-scale water, sediment and nutrient fluxes in the Nyabarongo River Catchment, Rwanda

Water is one of the most widely distributed substances, equally fundamental for humans and ecosystems. It is essential in sustaining all forms of life, food production, promoting economic development, and general wellbeing. However, it is becoming scarce and has particularly gained increasing attention in Sub-Saharan Africa.

Therefore, water availability, quality, and sediment delivery have become challenging issues threatening food supply, security, human health, and natural ecosystems. Therefore, water quality monitoring is essential and depends on different natural variability including spatial and temporal weather, hydrological conditions, land use, and management practices.

Nyabarongo wetland contributes to Rwanda's food security. Like other East African wetlands, it has different environmental problems due to the excess sediment and nutrient loads. Thus, this PhD research will model the large-scale water, sediment, and nutrient fluxes in the Nyabarongo River Catchment (NRC). Especially, it will determine water availability, assess nutrient and sediment loads, and analyze the impact of land use/cover and climate changes on water, sediment, and nutrient loads in the catchment in different scenarios.

It is part of the GlobE wetland project-reconciling future food production with environmental protection; however, it is jointly funded by DAAD and the Government of Rwanda. Indeed, the SWAT model was applied to achieve the objectives of this research. With the model, we will be able to understand the hydrological processes, analyze nutrient and sediment loads, and run land use /cover and climate scenarios for the sustainable management of water and land resources in Rwanda.
