  3. 2. Effects of afforestation of agricultural land on the water balance in Ethiopian Highlands

    University essay from SLU/Dept. of Soil and Environment

    Author : Mwala Silumesi; [2022]
    Keywords : acacia decurrens; aquaCrop Mode; afforestation; water balance; teff;

    Abstract : In this study, I examined how land use change affects the partitioning of water and how soil-plant interactions are impacted by yearly rainfall at a stand scale. Even though many studies have been conducted to evaluate the extent of land use change and the economic impacts, few have attempted to study the rapid farmer-driven afforestation with Acacia decurrens and also disaggregated dry, normal and dry seasons at stand scale.
