The Managing REsilient neXUs Systems through Participatory Systems Dynamics Modelling (REXUS) project offers a comprehensive strategy for mainstreaming Water-Energy-Food-Climate (WEFC) Nexus thinking and promoting Resilient Nexus Systems. Resilience in REXUS stands for the capacity of systems to adapt quickly to changes and disruptions. 

This is done through research and innovation activities that support multi-level and multi-scalar action in the domains of governance, policy development, decision making and implementation. REXUS: 

  • Puts people and institutions at the centre of Nexus.

  • Harnesses leading-edge participatory systems dynamics modelling to include all relevant stakeholders that influence Nexus systems or are impacted by them.

  • Models coupled resource flows for effective long-term planning and assessment of policies and adaptation strategies through scenario assessments.

  • Explores the potential for advancing WEFC Nexus management through the use of Remote Sensing, as for instance through climate risk assessments.

  • Co-analyses biogeophysical and socio-economic systems to identify effective ways for delivering the Sustainable Development Goals through a Nexus-centred process.

  • Assesses to what extent the Nexus approach fits into both existing and emerging legal instruments, and identifies diverse governance and institutional barriers to mainstreaming a Nexus approach.

  • Builds on the hypothesis that Ecosystem-based Adaptation is a cost-effective approach to enhance the resilience of Nexus systems, i.e. demonstrates the connection between biodiversity and the Nexus, and delivers a framework to leverage Nature-based Solutions.

  • Provides a wealth of practical tools, solutions, and roadmaps that support stakeholders (from local communities to countries) in the process of incorporating Nexus into their day-to-day routine activities and strategic decisions.
