Sustainable Integrated Management FOR the NEXUS of water-land-food-energy-climate for a resource-efficient Europe (SIM4NEXUS) (2016-2020)

Land, food, energy, water and climate are interconnected, comprising a coherent system (the ‘Nexus’), dominated by complexity and feedback. The integrated management of the Nexus is critical to secure the efficient and sustainable use of resources. Barriers to a resource efficient Europe are policy inconsistencies and incoherence, knowledge gaps, especially regarding integration methodologies and tools for the Nexus, and knowledge and technology lockins. SIM4NEXUS will develop innovative methodologies to address these barriers, by building on well-known and scientifically established existing “thematic” models, simulating different components/“themes” of the Nexus.

The key outputs of SIM4NEXUS are:

  • A Serious Game as an interactive experience for testing and evaluation of policy options and a visualisation tool assisting policy- and decision-makers in better understanding of policy implications for Nexus at various governance levels, geographic and spatial resolutions.
  • GeoPlatform integrating and interconnecting a series of available data and metadata sources on all themes of the Nexus, for decision and policy-making;
  • A Complexity Science library of integrated tools that use complexity science and Artificial Intelligence approaches as methodologies for integration of the Nexus components;
  • A Knowledge Elicitation Engine which will provide the impact of each action done in the Nexus to the ‘serious game’. Moreover, it will provide top-down learning based on the ‘serious game’ user decisions, and a bottom-up approach based on classical KEE methodologies applied to data;

The University of Exeter is providing input into numerous work packages within SIM4NEXUS and taking the lead on Thematic Models and Integration (Work package 3) which includes:

  • Coordination – data base – data flow semantics
  • Downscaling of climate/climate change and socio-economic scenarios
  • Thematic models: Application to all case studies under selected scenarios
  • Complexity Science tools- Selection and development of the integration methodologies
  • Implementation of the complexity science tools for each case study under different scenarios
  • Overall assessment of the complexity science models and integration approach in SIM4NEXUS
