New global indicators for the impacts of global changes on water quality to improve management and policy making

Host institution

International Institute for Applied System Analysis, Austria.

Project description

This project aims to develop innovative global indicators for water quality status and changes (especially eutrophication) in selected lakes worldwide, accounting for climate change and socio-economic development and land- use change. The proposed project includes mainly three parts:

1. Long-term trend (e.g, 1980-present) assessment of water quality for selected lakes worldwide. This will be done by integrating PCLake+ (lake water quality and ecological modeling) with nutrient load modeling (based on the GLOBIOM–CWatM–MARINA modeling framework developed as part of the ISWEL project) and global water quality dataset from Remote Sensing products for lakes and reservoirs (e.g., from World Bank and Copernicus)

2. Development of critical indicators by linking the long-term trend (e.g., trophic level change) back to the driving forces (e.g., climate change and socio-economic development, land-use change, river connectivity), and

3. Mid- and long-term projection and scenario analysis to provide policy and management recommendations with case studies (e.g., Lake Victoria, Lake Taihu)

Secondments
