Climate Change impacts on Hydrology, Ethiopia

This report aims to evaluate the impacts of climate change on both hydrologic regimes and water resources of the Upper Blue Nile River Basin in Ethiopia where observed hydrologic data are limited.

This report presents three steps for analyzing climate change impacts on hydrology and water resources.

The first is the construction of the climate change scenarios whereby the outcomes of multiple general circulation models (GCMs) are used to perturb the baseline climate scenario representing the current precipitation and temperature patterns.

The second is runoff simulation by using a simple two-tank hydrologic model due to the limited data availability and the scale of the sub-basins.

In the final step, climate change impacts on hydrology and water resources are examined using a set of indices.

Who we are

The Drylands Coordination Group (DCG) is a network for capacity building through exchange of practical experience and appropriate knowledge on food security in the drylands of Africa. The DCG networks in Eritrea, Ethiopia, Mali, and Sudan consist of NGOs as well as research institutions and governmental structures. DCG Norway administers funds from Norad to research projects and from the Norwegian Ministry of Foreign Affairs to information and policy work linked to the UNCCD and dryland challenges.

Our goal

The overall goal of DCG is to contribute to improved food security for vulnerable households and communities in the drylands of Africa. DCG intends to reach this goal by addressing core challenges related to the increased pressure on natural resources which leads to food insecurity in the drylands. We focus on enhancing the capacity of member organisations, networks and other stakeholders to address these challenges, and through this contribute to strengthening access to natural resources for vulnerable households and communities.

How we work

DCG projects include action research, studies, workshops, capacity building and policywork. The projects are designed and implemented by the national DCG groups, and aim to create synergy effects, build capacity and be relevant and applicable also outside of DCG.

Our product is knowledge that is used to strengthen the work of our members, influence policy makers and ultimately improve the livelihoods and food security of farmers and pastoralists in the drylands of Africa.
