“We are at a critical juncture in human history, which could lead to widely contrasting futures,” writes the chairman of the National Intelligence Council (NIC) Christopher Kojm in the council’s latest forward-looking quadrennial report, Global Trends 2030: Alternative Worlds, released yesterday.

This year, principal author Mathew Burrows and his colleagues focus on a series of plausible global scenarios for the next 20 years and the trends or disruptions that may influence which play out. Among the most important factors in these projections are demography and the environment.

“There is as much of that water on the planet today as when the first amphibian flopped ashore; as much as when the ancient Greeks divined the future in the babble of brooks,” writes William Wheeler in The Christian Science Monitor. “So why do experts in science, economics, and development warn that a ‘global water crisis’ threatens the stability of nations and the health of billions?”

With the start of part two of Circle of Blue and the China Environment Forum’s Choke Point: China series, the focus has broadened from looking more narrowly at water scarcity and energy to including the effects of food security and pollution in China too.

“From an environmental point of view,” said Circle of Blue Senior Editor Keith Schneider, the question is, “can a nation that big, operating at such a scale maintain its sustainability?”

Few regions are more environmentally insecure than South Asia.

The region faces rising sea levels and regularly experiences coastal flooding – of particular concern in a region with heavily populated and arable-land-rich coastal areas. Additionally, it is highly vulnerable to glacial melt. The Western Himalayas, which provide water supplies to much of South Asia, have experienced some of the most rapid melt in the world.

Sub-Saharan Africa is a key region both for conservationists and those working for improved public health. Nine of the world’s 34 biodiversity hotspots are in sub-Saharan Africa, as are two of the five most important wilderness areas. This hotbed of biodiversity is also home to many of the world’s most rapidly growing populations and swelling urbanization, which is putting increased pressure on natural resources.

Access to safe water is often taken for granted in developed countries. But last week at the 22^nd annual conference of the Society of Environmental Journalists, panelists argued that the impact of dirty water on women’s health is an important but neglected story, not only in developing countries like Nigeria, but also in the United States.

Where the wide, muddy waters of the Songhua River flow north from Jiamusu to the Russian border, just 150 kilometers (90 miles) distant, the whole of China’s largest treeless prairie sweeps to the horizon. This expanse of fertile grasslands endures the dark fright of cold Siberian winters and the raging winds of Mongolian summers. At night, in the scattered villages, the sky fills with stars so thick and bright that walking along unlit streets is easy.

In recent weeks, militants in Pakistan have escalated their hostile rhetoric toward India. The subject of their ire is water. Hafiz Saeed, the head of militant Islamist group Jamaat-ud-Dawa, has warned that India plans “to make Pakistan barren” by preventing the waters of the Indus Basin from flowing downstream to Pakistan.
