The report summarizes the key ACEWATER2 project scientific achievements of the activities implemented by the African CoEs (Centers of Excellence), supporting Institutions, leading experts and the JRC. The outcomes of few ongoing research projects at JRC complements the overall framework. The first three chapters focus on the analysis of the WEFE (Water-Energy-Food-Ecosystem) nexus assessment at regional scale over the two formerly existing networks of CoE, in Western and Southern Africa, and the 2018 newly established network of CoE in CentralEastern Africa.

The report addresses a twofold objective, in order to provide an overview of:

- the Human Capacity Development (HCD) priorities in the water sector in Africa;
- the Development Priorities of the Water Sector placed in the context of Agri-Energy sectors

The general objective of the present report is to frame the state-of-the-art on the geothermal resource development in East African Countries (Eritrea, Djibouti, Ethiopia, Kenya, Uganda, Rwanda, Burundi, Tanzania and Comoros) and two Southern African countries (Malawi and Zambia). For the sake of simplicity, all the above countries will be collectively referred to as “East African countries”.

In the framework of the project scientific component, the CEANWATCE, this project addressed the WEFE nexus interdependences and evaluated sustainable bridging-gap solutions. The specific objectives was to perform hydrological and water balance assessments, including water uses within a scenario based analysis under different climate pressures and management practices focusing on the Lake Victoria basin (LVB).

Extreme climate events such as drought and floods with severe impacts over the Greater Horn of Africa (GHA) have been on the rise over the past decades. These events negatively impact the regional ecosystem, livelihood, and economy which heavily depends on rain-fed agriculture, while in the energy sector largely depends on hydropower, thus shifts and variability in rainfall and temperature could hinder the development and economic growth of the region.

Hydrological fluxes, land use and climate change are significant processes in the biogeochemical processes and agricultural productivity in the Lake Victoria Basin. The objective was to elicit hydrological trends with attendant quality and quantity components, assess land use change patterns as well as implications of climate change on maize yields in the LVB.

This study Examines the Water, Energy, Food and Ecosystem (WEFE) nexus assessment in the Niger Delta basin of Nigeria. One major component of the Niger Delta basin is that it has been a constant receptor of the unrelenting pressure and assault in the ecosystem and this has adversely affected the living condition of the people.
