Assessing the impacts of land use land cover change on water resources. The case of Nile River Basin, Ethiopia

Article scientifique 2022 Anglais

Résumé

Abstract This study investigated the trends of climate change and land use land cover changes of Nile river basin. The trends of climate were analyzed using Mann-Kendall test, Sen’s slope estimator test and innovative trend analysis method. NDVI and Transformation matrix was employed to analyze the spatial and temporal patterns of land cover and vegetation patterns during 2001–2013. The findings revealed that the forestland and water resource was decreased by 3429.62 Km2 and 81.45 Km2 respectively. On the other hand, grassland, cultivated land, urban 2779.33 Km2, 535.34 Km2 and 0.65Km2 increased respectively. Reduction of NDVI value by 0.1 was observed in 2013 in the southern part of the basin. A significant increasing trend of precipitation was observed in Gondar (Z = 1.69) and Motta (Z = 0.93) stations. However, the trend was decreasing in Adet (Z= -0.32), Dangla (Z= -0.37) and Bahir Dar stations. The trend of temperature was increasing in all stations. The significant changes in land use land cover might be caused by human induced activities in the basin.
