ARUA Water Centre of Excellence Development: "Water for African SDGs" Where: SDGs (Sustainable Development Goals), U (university), CoE (Centre of Excellence), CSES(Complex Social-Ecological System) & landscape/catchment/watershed: synonymous.  The "Water for African SDGs" project will establish & develop the ARUA Water CoE as an effective, high-performance, hub & network of 8 African Universities' researchers & post graduate students. CoE research development will be based on understanding humans living on earth as the intricate coupling of society with the natural world - CSESs. We will forefront community engagement & knowledge sharing for sustainability. We will use research to catalyse change towards social and ecological justice and sustainability, paying attention to African community water and sanitation needs.       The Water CoE has developed a systemic image of the SDGs as a planning, practice & evaluation tool. The image has SDG 6, Clean water & sanitation, at the centre, linking two primary water cycles: i) Water in a Catchment (rainfall, run-off, ground water recharge, evapo-transpiration, evaporation); &  ii) Water Services - supply & sanitation (raw water from the natural resource, often in dams, pipes & pumps to water treatment works, treated potable water to households, waste water to treatment works & discharge into the natural resource).        Several nodes place their water research in a climate change context (SDG 13), and acknowledge that water is integral to SDG 15 (life on land), 11 (sustainable cities & communities), & 12 (responsible consumption & production), Effective water resource management, supply and sanitation requires good water governance by strong institutions (SDG 16). The Water CoE itself embodies SDGs 17 (partnerships to reach goals), 4 (quality education) & 5 (gender equality).       Each CoE node has strengths in different parts of these cycles. This project brings together strengths, so nodes can flexibly link & respond innovatively to research funding calls, & effectively apply research. Capacity-building, exchanges and mentorship will mainly be addressed through the development & delivery of a 3-day course by each node, to 14 participants from 3-5 other nodes. Participants will be doctoral students, early-, mid-career & established researchers. Nodes will host a course on their primary strength, nodes will co-develop courses out of secondary strengths.        In Year 1, the hub (Rhodes U), will deliver a core foundation course to 3 delegates from each node (total 21), on Adaptive Integrated Water Resources Management (A-IWRM), including the CSES concept, transdisciplinarity and water governance. Node courses will run over Years 1 & 2, and an early identification of course areas is: Landscape restoration & catchment water use (Addis Ababa U, Ethiopia), hydrology, geohydrology & hydraulic regimes for IWRM (U Dar es Salaam, Tanzania), optimising benefit from dams (Cheikh Anta Dio U, Senegal), biodiversity, natural resource management, water-energy-food nexus  (U Rwanda), urban water pollution (U Lagos, Nigeria), urban water quality design (U Cape Town, South Africa), & water in future cities (Makarere U, Uganda). Course days will include time to work on research proposals. In Year 3, activities will focus on grant applications and a Water CoE delegation attending a relevant international conference to present the outcomes of the whole project.       Over the 3-year period, each node will have one opportunity to invite/visit an international specialist, & by the end of year 3 at least 3 collaborative research projects will be running, each progressing an SDG challenge-area. Spin-off companies in water & sanitation could be emerging, and each node will have community-based water and/or sanitation impact successes. At least 24 early career researchers and 24 doctoral students will be mentored through the CoE. We will demonstrate the clear emergence of an African water research cohort, addressing water-related SDGs, with positive outcomes and impact. The Global Challenges Research Fund (GCRF) supports cutting-edge research to address challenges faced by developing countries. The fund addresses the UN sustainable development goals. It aims to maximise the impact of research and innovation to improve lives and opportunity in the developing world.
