Reported driving factors of land-use/cover changes and its mounting consequences in Ethiopia: A Review

Obviously, there is land-use/cover change with multifaceted driving factors and associated adverse impacts out there in different parts of Ethiopia. Evidence from published journals justifies this fact but not yet compiled in a manner to convey information on the trend of change and its criticality with the aim to handle the problems. Thus, filing up all the driving factors and its adverse out come from different corners...

Rural Households’ Access to Water Resources Under Climate Impacts Based on Field Evidence in Tigray Region, Ethiopia

The climatic condition in Ethiopia is semi-arid and this has implications especially for rural communities in the country that are largely dependent on surface water. In water scarce areas across four districts in the Tigray region we carried out a survey of 595 households, and held two shared dialogue workshops. In these we examined the following issues: (i) access to water in relation to sources, distances covered,...

A view of road transport in Africa

Transport sector is usually divided into four main modes: road, air, maritime and rail modes. In sub-Sahara Africa, road appears as the dominant mode. Railways were developed during the colonial period but almost abandoned since the independence in most countries. Air transport once seen as sign of economic prosperity and instrument of sovereignty is far from being competitive. Maritime transport is mainly on coastal...
