The nexus approach to the sustainable management of water, soil, and waste integrates environmental management and governance across sectors and scales. This approach requires a holistic understanding of the interlinkage of all related environmental processes, while also taking into consideration global change and socioeconomic aspects.
Exploring these interlinkages and advancing a nexus-oriented management approach requires integrated modeling tools. However, no single modeling tool is available or conceivable that can cover all processes, interactions and drivers related to the management of water, soil and waste resources.
To help overcome this challenge, the UNU Institute for Integrated Management of Material Fluxes and of Resources (UNU-FLORES) has developed an interactive Nexus Tools Platform (NTP) for comparison of existing modelling tools related to the water-soil-waste nexus. Currently, the NTP database consists of 60 models from around the world. The platform provides detailed model information and advanced filtering based on real-time visualizations, and will continuously grow with the input and feedback from model developers and model users.
