1 A draft G-WADI strategic position paper Wouter Buytaert

2 G-WADI The Global Network on Water Resources Management in Arid and Semi-Arid Zones (G-WADI) network of UNESCO was established in 2003 to address the urgent need for increased regional and international cooperation on sustainable development of arid and semi-arid regions. Objectives of G-WADI Objective 1 Knowledge of hydrological systems Objective 2 Capacity building Objective 3 Dissemination to end-users Objective 4 Exchange of experience Objective 5 Integrated basin management

3 Achievements Process understanding Near real-time precipitation estimates Hydrological monitoring and forecasting Water harvesting Regional frequency analysis Chemical and isotopic tracers

4 Achievements Products and tools PERSIANN, PERSIANN-CSS, PERSIANN-CDR Drought Atlas of Latin America and the Caribbean Latin American and African Flood and Drought Monitors Streamflow forecasting in African basins ICI-RAFT: Regional analysis of frequency tools

5 Achievements The PERSIANN suite (Kuolin et al., 2013; Ashouri et al., 2015)

6 Achievements The PERSIANN suite

7 Achievements Drought atlas of Latin America and the Caribbean (MWAR LAC)

8 Achievements Latin American and African Flood and Drought Monitors (MWAR LAC)

9 Achievements Capacity building Website as knowledge clearing house Over 30 workshops and training activities establishment of 3 UNESCO category 2 centres 244 publications related to G-WADI Special journal issue

10 Core strengths Scientific foundations -> Levering the latest science and technologies Science translation and policy shaping -> Identify stakeholders and problems The network -> Dissemination, catalysis, and prioritization

11 Opportunities New scientific developments Policy support, training, and knowledge exchange Sustainable development goals

12 Opportunities Climate services the provision of climate information in such a way as to assist decision-making (Hewitt et al., 2012) Users User Interface Platform Climate Services Information System Observations and Monitoring CAPACITY DEVELOPMENT Research, Modelling and Prediction

13 Opportunities Socio-hydrology (Montanari et al., 2013) Natural Water Availability Water Supply Buffering Capacity (Groundwater & Reservoirs) Reaction Propensity (increasing supply versus reducing demand) - Water Demand - Sensitivity Historical Water Availability - - Meteorological Hydrological Drought Severity Drought Severity Sensitivity to Meteorological Drought - Agricultural Drought Severity Perceived Severity of Drought Sensitivity to Hydrological Drought Sensitivity to Agricultural Drought - Socio-economic Drought Severity - Benefit from Water Supply Sensitivity to Socio-economic Drought Relative importance of Agriculture Water-benefit efficiency A socio-hydrological model of drought (P. Blair)

14 Opportunities Citizen science and participatory approaches Karnali basin, Nepal

15 A demand-driven approach Leverage the regional centres to identify policy issues and bottlenecks; Identify priorities and common interests; Structure and mobilize the research community around these issues; Leverage funding; Deliver tailored products and tools using the latest technologies;

16 Sustainable development goals

17 Challenges Science policy translation Policy influence Making the network work Communication within the network and outside Using the website optimally Maintaining and supporting existing tools and products
