The Fall of the Water

Report - Fall of the water

The mountains of Asia, including the Himalayas, are facing accelerating threats from a rapid rise in roads, settlements, overgrazing and deforestation. There is concern that the region's water supplies, fed by glaciers and the monsoons and vital for around half the world's population, may be harmed alongside the area's abundant and rich wildlife. This is the main conclusion of the report Fall of the Water.

The report was released in advance of the 2005 World Summit in New York. At the summit heads of state assessed the status of implementation of the Millennium Development Goals. The MDGs include a target of reducing by half the proportion of people without sustainable access to safe drinking water.

GLOBIO contribution

GLOBIO2 was employed to specifically address the environmental impacts of infrastructure development. In addition GLOBIO3 was applied for a comprehensive assessment of the cumulative impacts of human development and climate change on biodiversity.

The region of study was the greater Asian mountain range of the Himalayas-Hindu Kush, Tibet and Tian Shan. The study also included the effects down river.

The main conclusions of the model analyses are:
