The European case study will be extended towards global level. It will be lower in detail and higher in integration, focusing on global challenges (e.g. increasing food demand) and international trade features connected to the Nexus. While in principle addressing large world regions, downscaling to pinpoint hotspots (using gridded information) and geographic regions is possible. The policy priorities include food security, resource efficiency, low-carbon energy and climate change mitigation, water availability and vulnerability to water stress and floods, water quality, biodiversity and ecosystem services. The prevailing Nexus policy challenges to be addressed relate to (i) the impact of water constraints on food security and broader human development (clean water for human use; industrial and energy water demands), as well as (ii) the impact of climate change on aggravating or relieving water problems. Nexus-compliant approaches search for broad-scale synergies and trade-offs between options in achieving multiple goals, e.g. by combining water allocation demands among sectors. Using a simplified integrated assessment model allows for exploring divergence, robustness and flexibility of global development pathways and options like infrastructure investments. Relevant aspects are subject of UN Conventions (UNFCCC, UNCBD, UNCSD, Ramsar Convention, UNCCD) and reside under a variety of UN (UNEP, UN-Water, FAO, IPCC, IPBES, others) and other international organisations (OECD, G7, others). Several of the Thematic Models have global coverage. This will enable us to explore the creation of a Serious Game at Global Level, with a strong scientific background, but limited in scope due to the high aggregation level.
