Abstract [en]


Like other developing countries, forest conversion to agricultural land has been a common practice in Kenya for the last four decades. Apart from illegal logging, the main cause is the growing population. For most developing countries where majority rely on agriculture for food production, conversion of forests into agricultural land is likely to occur. Kenya is one among such countries and is where the study basin is located. Knowledge of hydrological studies is crucial for proper planning and decision making of limited water resources in river basins. Even in regions where data is limited, changes in land use is a concern to many basin communities over the globe including Arror inhabitants since it has an impact on stream flows. Despite Arror downstream communities’ claims on reducing river flows, scientific proof on this is lacking. Such kind of belief/claim can result to conflicts (Downstream vs. Upstream water users). The main objective of this thesis was therefore to determine the effect of land use changes on Arror basin hydrology, focusing on the impact of deforestation since it has been the main land use change for the last four decades. The overall intention of the study is to verify the downstream basin’s inhabitant’s hypothetical thinking and also create an information foundation base for other future studies in the basin. Based on the lessons learned in this study, several recommendations have been highlighted, including land satellite rainfall data to augment the rainfall data obtained from the relatively sparse rain gauge network in the basin.
