TL;DR: To conserve long-distance movement of the ungulates in this area, it will be necessary to remove or mitigate the barrier effects of the existing and planned roads and railroads and to adopt a landscape-level approach to allow access by ungulate to wide ranges throughout their distribution.

TL;DR: As changes in LULC and climate are expected to intensify in the future, it is important to study further hydrological responses considering these changes to devise future sustainable land and water management strategies.

TL;DR: In this article, the authors proposed mitigating strategies that would contribute to the improved planning and management of reservoirs in similar regions, and the overall objective of this study was to understand reservoir sedimentation in this tropical highland watershed and to propose its mitigating strategies.

TL;DR: In this paper, the authors analyzed soil erosion rates from 1973 to 2006, identified erosion hotspots, and proposed possible soil conservation scenarios, considering the land use change at the following three periods: 1973, 1985 and 2006.

Abstract: Soil erosion is a significant problem in the Ethiopian highlands. The objective of this study was to investigate how farmers perceive the severity of soil erosion in the Upper Blue Nile Basin. The study is based on a detailed survey of 300 households and 1,010 plots owned by these households in three watersheds. Descriptive statistics and a partial proportional odds model were applied to analyze factors that affected farmers' perceived soil erosion severity at the plot-level. Results showed that variables such as plot distance from the residence, plot shape and position on hill slopes affected farmers' perceptions of soil erosion severity, as well as the amount of rainfall during the growing season. Farmer interaction with extension service agents also affected farmers' perception of soil erosion severity. Despite their expected importance, education and number of livestock owned had no effect on the farmers' perception of soil erosion. The results indicate that farmers' perceptions generally match empirical and theoretical findings on soil erosion determinants; thus, farmers should be considered as important partners not only to counter soil erosion, but also to obtain local expertise on soil erosion severity and restoration of degraded land. © 2016 The Authors.
