This study assesses the literature evidence on climate change risk,resilience,and adaptation measures used among rural farmers in East Africa.A systematic literature review was conducted comprising 30 papers from the Web of Science database published during *** results of the literature review showed that climate change risks have direct impacts on agricultural practices,limit rural farmers’resilience,and exacerbate their food *** most prominent risks are increasingly shorter wet seasons and heat stress,which lead to droughts and food production *** to climate risks,farmers in East Africa adopt various adaptation strategies such as mixed-and inter-cropping,conservation tillage,early planting,crop diversification,***,this review summarizes the determinants of climate change adaptation strategy selection by farmers in East Africa,including age,gender,household size,economic status and household assets,landownership and livestock,education and training,***,the choice of adaptation strategies to climate change is strongly determined by the gender of household heads,the results of gender as a determinant of adaptation differ greatly between different case *** female-headed households(FHHs)tend to perceive changes in temperature more readily than male-headed households(MHHs),the latter are generally more likely to adopt different adaptation *** the resilience and adaptation measures used by rural farmers in East Africa now,improved weather forecasting and early warning systems are needed as a better direction towards the future.

Soil erosion affects land qualities and water *** problem is severe in Ethiopia due to its topographic *** present research was aimed to estimate spatiotemporal changes in land-use/land-cover pattern and soil erosion in the Yezat watershed in *** study was carried out by using landsat imageries of 2001,2010 and *** were classified into categories using supervised classification by maximum likelihood *** were also classified into different biomass levels by using Normalized Difference Vegetation Index(NDVI)*** Universal Soil Loss Equation modeling was applied in a GIS environment to quantify the potential soil erosion *** area under grassland,woodland and homesteads have increased by 610.69(4%),101.69(0.67%)and 126.6 ha(0.83%)during *** extent of cultivated land and shrub/bushland was reduced by 323.43(0.02%)and 515.44 ha(3.41%),respectively,during the same *** vegetation cover in the watershed decreased by 91% during 2001-2010,and increased by 88% during *** of NDVI values indicates better ground cover due to implementation of integrated watershed development program in the *** estimated annual soil losses were 7.2 t ha^(-1) yr^(-1) in 2001,7.7t ha^(-1) yr^(-1) in 2010 and 4.8t ha^(-1) yr^(-1) in *** interventions are necessary to improve the status and utilization of watershed resources in response to sustainable land management practices for sustainable livelihood of the local people.
