The EU/FP7  Assessing Climatic change and impacts on the Quantity and quality of Water (ACQWA) project aims to assess the impacts of a changing climate, focusing on the quantity and quality of water originating in mountain regions, particularly where snow- and ice melt represent a large, sometimes the largest, streamflow component. The goal of the project is to use advanced modelling techniques to quantify the influence of climatic change on the major determinants of river discharge at various time and space scales, and analyse their impact on society and economy, also accounting for feedback mechanisms. Regional climate models will provide the essential information on shifting precipitation and temperature patterns, and snow, ice, and biosphere models will feed into a hydrological model in order to assess the changes in basin hydrology and seasonality, amount, and incidence of extreme events in various catchment areas. Environmental and socio-economic responses to changes in hydrological regimes will be analyzed in terms of hazards, aquatic ecosystems, hydropower, tourism, agriculture, and the health implications of changing water quality.

Main deliverables and outcomes

UNEP/DEWA/GRID-Europe specific tasks:

The complexity inherent to the chain of processes involved from climatic, to cryospheric and hydrologic models, all of them impacting on different compartments of human and natural systems, all this through different scenarios and across several regions, as described in the other project WPs, justifies the definition of a well organized data warehouse for the ACQWA project. Based on the long experience in managing data and metadata through the Internet from many international programs, developed by GRID-Europe as part of the Division of Early Warnings of UNEP, the ACQWA Spatial Data Infrastructure (ACQWA-SDI) will:
