Towards indicators for water security - A global hydro-economic classification of water challenges
Year: 2015
Type: book
Abstract: Following a risk-science perspective IIASA's Water Futures and Solutions Initiative has developed a novel indicator for measuring water security and water challenges. A hydro- economic classification depicts countries and/or watersheds in a two-dimensional space using normalized indicators of economic-institutional coping capacity and hydrological complexity. Lacking adequate data on institutional capacity that was acceptable to stakeholders, we use in a first attempt GDP per capita as proxy for economic-institutional coping capacity. Hydrological complexity is measured by an weighted indicator based on four component indicators: i) total renewable water resources per capita; ii) intensity of water use; iii) runoff variability; and (iv) dependency of external water resources. Indicators were elected to provide global data coverage and future projections using the results from global hydrological and water use models. Here we create a hydro-economic classification of countries for the year 2000 using data from the Food and Agriculture Organization AQUASTAT database and ISI-MIP hydrological model results.
