Water Futures and Solutions fast-track analysis

The successful completion of the fast-track analysis under the global Water Futures and Solutions (WFaS) initiative, is a major achievement of the Water (WAT) Program. The analysis has yielded the first set of multi-model, quantified scenarios of water demand with a focus on the domestic, industrial, and energy sectors.

The WAT program carried out several collaborative projects in 2015 to improve understanding of local water issues related to food, energy, transboundary water management, and ecosystem services. The work aimed to identify joint solutions working across sectors and scales. In practical terms this means that WAT now covers all aspects of water use [1][2][3].

The WFaS fast-track analysis constitutes the first comprehensive, multi-model assessment of water availability and demand, with full consistency of climate, energy, and land-use scenarios.

The fast tracking uses ongoing research to develop a set of (preliminary) scenarios with quantitative water projections consistent with global scenario processes in other sectors [4][5]. This work is based on the Shared Socioeconomic Pathways and the Representative Concentration Pathways and associated climate model projections that were developed for the Intergovernmental Panel on Climate Change Fifth Assessment Report and beyond. The scenarios also take into account changes in population and gross domestic product. As part of the assessment, water insecurity hot-spots have been identified, with a focus on the occurrence of joint water, energy, and food insecurity. The results indicate that global demand for water could more than double by 2050, increasing pressure on already scarce water resources.

WFaS also published interim reports on the conceptual framework for applied scenarios, building water-use scenarios, and a global hydro-economic classification of hydrological challenges and socioeconomic coping capacity.
