In agriculture, surveying is required to prepare topographical maps that indicate variations in the level of the land's surface. Topographical maps are necessary as a base for the preparation of research station maps which include layout of field, buildings, roads, and soil conservation measures.
The International Center for Tropical Agriculture (CIAT), in collaboration with our national research partners, has been working in Africa for the last 30 years. Our cutting-edge science helps policy makers, private sector, scientists, civil society, and farmers respond to the most pressing challenges of our time.
Although Ethiopia has abundant land for irrigation, only a fraction of its potential land is being utilized. This study evaluates suitability of lands for irrigation using groundwater in Ethiopia using GIS-based Multi-Criteria Evaluation (MCE) techniques in order to enhance the country's agricultural industry. Key factors that significantly affect irrigation suitability evaluated in this study include physical land features (land use, soil, and slope), climate (rainfall and evapotranspiration), and market access (proximity to roads and access to market).
Land degradation is a major challenge limiting crop production in Ethiopia. Integrated soil and water conservation is widely applied as a means to reverse the trend and increase productivity. This study investigated the effects of such integrated approaches at two sites, Jeldu and Diga, in Western Ethiopia. A split plot design with physical soil and water conservation in the main plots and agronomic practices in the sub plots was employed.
This study reviewed the status of natural resources and the driving forces for change, as well as past and ongoing approaches in natural resource management at the watershed scale in Ethiopia. First, we reviewed established environmental policy tools and the legal and policy framework, and determined whether innovative financing mechanisms are working in other areas with a similar context. We undertook stakeholder analyses and mapping to identify key stakeholders, and to assess their possible roles in the implementation of a sustainable financing mechanism for watershed rehabilitation.
