Forecasting trade-offs between the food-energy-water-environment nexus and opportunities for adaptation

Host institution

Vrije Universiteit Brussel (Belgium).

Project description

A growing and developing populations puts more demand on food and energy production while climate change impacts may have (mainly negative) effects on the productivity.

The objective of this study is to have a tool that can predict water quality under global change scenarios and that is able to assess trade-offs and synergies between the food-energy-water-environment nexus. In this project we aim to tackle this by 1) model integration considering water quality and food and energy production using an integrated model composed by (SWAT+ (linking agriculture-water-environment) 2) model application for water quality simulation at small to global scales using SWAT+ and model evaluation using local and global datasets for flow data, water quality data, crop yields including remote sensing products 3) multi-sectoral analysis including trade-offs within the foodenergy-water-environment nexus for different ISIMIP scenarios climate and land cover scenarios through improved reservoir representation and reservoir management optimisation.
