Glacier melt of the Himalayas is a key water source for agriculture during dry periods in central and south Asia. Most major rivers originating in high-mountain Asia pass through different countries.
Upstream countries, such as Kyrgyzstan, Tajikistan and Nepal, rely on hydropower, and downstream countries such as Uzbekistan and Turkmenistan rely on water from upstream ones. The current and future states of river discharge are therefore matters of high political sensitivity. Tobias Bolch comments a publication of a scientific colleague in “Nature”.
