Multi-Scale analysis of the impacts of soil and water conservation practices and landscape on grain yield and return on investment in the sub-humid ethiopian highlands.

Ethiopia's sub-humid highlands face a critical challenge in balancing agricultural productivity with land degradation. This study explores the effectiveness of soil and water conservation practices (SWCPs) in addressing this challenge. We investigated the interaction effects of types of SWCPs, landscape positions, and location on () and wheat () yield.

Evaluating land suitability and water availability for surface irrigation in the Abbay basin of Ethiopia.

This study was conducted in the Abbay basin of Ethiopia to evaluate land suitability for irrigation considering both surface and groundwater sources using the analytic hierarchy process. Multiple factors which affect irrigated agriculture productivity were considered, and an 85% threshold was applied to identify irrigable land. The suitability result was validated using ground truth data from existing irrigation projects for surface water sources and depth to groundwater data for groundwater sources.

Dataset for mapping groundwater contaminant risk using the DRASTIC model for a case study in Ethiopia.

This paper contains the data that helps in mapping groundwater contaminant risk (nitrate and phosphate) using the DRASTIC model for a case study in Ethiopia. The data contains a total of 9 parameters, each having data points ranging from 10 to 33 (196 records in total). About 52 % of the data points from 7 parameters (depth to water table, aquifer media, soil, types of vadose, transmissivity, aquifer thickness, and hydraulic conductivity) allows the model to predict contaminant risk levels in the groundwater.
