Impact of Land Use and Climate Change on Stream Flow, Sediment and Pollution Dynamics in Kagera River Watershed

Abstract: 
Kagera River is one of the most important incoming rivers to Lake Victoria with an annual inflow of about 7.5 km3 into the Lake and is also important to the River Nile which is the single outlet of Lake Victoria. The Kagera River is therefore important for ecosystem health and human wellbeing in the Lake Victoria Basin. However, the Kagera River Basin is facing increased degradation as a result of rapid population growth, agricultural and livestock intensification characterized by unsustainable land use and management practices, which are threatening the basin’s freshwater resource base, and associated ecosystem services for both upstream and downstream users. Climate change and variability exacerbates these threats. This study will assess the impact of land use change and climate change on stream flow, sediment and pollution dynamics in the Kagera River Watershed; and the likely land use policy interventions necessary to contribute to the sustainable use and management of the basin’s natural resources.
La rivière Kagera est l’une des rivières les plus importantes entrant dans le lac Victoria avec un apport annuel d’environ 7,5 km3 dans le lac, et elle est également important au fleuve Nil qui est la seule sortie du lac Victoria. La rivière Kagera est donc importante pour la santé des écosystèmes et le bien-être humain dans le bassin du lac Victoria. Cependant, le bassin de la rivière Kagera est confronté à une augmentation de la dégradation en raison de la croissance rapide de la population, de l’intensification de l’agriculture et de l’élevage, caractérisée par l’utilisation non durable des terres et les pratiques de gestion, qui menacent les ressources de l’eau douce du bassin et des services d’écosystème associés pour les utilisateurs en amont et en aval . Le changement climatique et la variabilité accentuent ces menaces. Cette étude vise à évaluer l’impact du changement d’utilisation des terres et le changement climatique sur le débit, les sédiments et la dynamique de la pollution dans le bassin versant de la rivière Kagera, et les interventions susceptibles de politique d’utilisation des terres nécessaires pour contribuer à l’utilisation durable et à la gestion des ressources naturelles du bassin.

The 2012 RUFORUM Biennial Conference is the third in the series. The main objective of the Biennial conferences is to provide a platform for agricultural research for development stakeholders in Africa and beyond to actively exchange findings and experiences, while at the same time learning lessons towards improving performance of the agricultural sector and ultimately people’s livelihoods. The biennial conference is RUFORUM’s most comprehensive meeting for the diversity of stakeholders in agriculture. It is especially dedicated to graduate students and their supervisors, grantees in RUFORUM member universities and alumni. It is a platform for peer review, quality control, mentorship, networking and shared learning. The third Biennial Conference was attended by 657 participants. This record contains an extended abstract accepted under the theme of Enhancing Natural Resource Management.
