Water resources and Tibet • Tibet is the “water tower" of Asia and rivers originating in Tibet (e.g. Mekong, Yellow river, Yangthze, Yarlung Tsampo, Indus) support hundreds of millions of people downstream • Perennial flows of these rivers largely rely on the constant flux of the Tibetan glaciers • Annual hydrological transfer to downstream countries total 577 km3 from a basin of 1.1 million km2 • Mountain regions are considered the “blackest box of black boxes” in the global hydrological cycle (increased specific yield, seasonal delay of discharge, decreased seasonal variability) Author, presenter. Organization PwC www.ecoregionalfund.com
Water resources and Tibet Values: • Water supply • Pivotal role in sustaining soil fertility • Hydropower (1300 TWh) • Plateau lakes are of ecological and religious importance Author, presenter. Organization PwC www.ecoregionalfund.com

Modelling of water resources • Water is key in bridging the gap between potential and actual production • Watershed shows limited response to changes in land use and water management – shallow soils, steep slopes, low water holding capacity • SWAT is a suitable tool to address the effects of management, climate and land use change scenarios on the water resources at various scales Author, presenter.
