Billion-plus people to lack water in 2050: study

“More than one billion urban residents will face serious water shortages by 2050 as climate change worsens effects of urbanization, with Indian cities among the worst hit, a study said Monday.

“The shortage threatens sanitation in some of the world’s fastest-growing cities but also poses risks for wildlife if cities pump in water from outside, said the article in the Proceedings of the National Academy of Sciences.

“The study found that under current urbanization trends, by mid-century some 993 million city dwellers will live with less than 100 liters (26 gallons) each day of water each — roughly the amount that fills a personal bathtub — which authors considered the daily minimum.

“Adding on the impact of climate change, an additional 100 million people will lack what they need for drinking, cooking, cleaning, bathing and toilet use.

“”Don’t take the numbers as destiny. They’re a sign of a challenge,” said lead author Rob McDonald of The Nature Conservancy, a private environmental group based near Washington.

“”There are solutions to getting those billion people water. It’s just a sign that a lot more investment is going to be needed, either in infrastructure or in water use efficiency,” he said.”

No current water crisis, but warning bells must be heeded, department concedes

South African boy drinks clean water.“Department of Water and Environmental Affairs water services chief director Helgard Muller has conceded that there are serious issues surrounding the efficient use of water and, if these are not tackled, “we are heading for a crisis in certain systems”.”

““However, I would not call it a national crisis,” said Muller during the United Association of South Africa (UASA) Water Security seminar, held last month in Johannesburg.”

“University of Pretoria department of geography, geoinformatics and meteorology head Professor Hannes Rautenbach said that climate change in South Africa was a reality in terms of temperature, but not so much in terms of the amount of rainfall a year.”

““However, it seems that the seasons are shifting with the result that summer rain- fall seasons may in future be shorter and winter rainfall seasons longer. This means that excellent planning is needed to prevent possible water shortages during dry spells in future,” Rautenbach said.”

“UASA CEO Koos Bezuidenhout concurred that South Africa was facing a serious water situation.”

““With this conference, we aim to signal the start of a loyal resistance programme and not [one of] confrontation, but of earnest cooperation with the authorities to solve the country’s water problems,” said Bezuidenhout.”

UK relies on ‘virtual’ water from drought-prone countries, says report

Cut flowers from Kenya

“We must recognise how the UK’s water footprint is impacting on global water scarcity. We should ask whether it is right to import green beans – or even roses – from water-stressed countries like Kenya,” said professor Peter Guthrie, chair of the group of engineers who compiled the report. “The burgeoning demand for water from developed countries is putting severe pressure on areas that are already short of water. Our water footprint is critical”, he said.

“The report backs analysis by the UK chief scientist, John Beddington, the World Bank and others who say that water shortages are worsening, especially in developing countries. More than 700 million people in 43 countries are now regularly affected by water scarcity and this is expected to grow as a result of climate change, population growth, the switch to meat-based diets in countries such as China, rapid urbanisation in Asia and the pollution of rivers and lakes in many developing countries.”

How We Can Stave Off the Triple Threat of Climate, Water and Food Crises

“There is growing recognition that water is the “key medium through which climate change impacts will be felt.” Climate impacts on water will directly affect agriculture. And, of course, agricultural practices can both impact and mitigate climate change. Yet, all three–climate, agriculture and water–are facing severe crises. It is the dramatic convergence of these crises that compel us to shift away from the dominant industrial agriculture model toward more sustainable and just alternatives.

“Ultimately, agriculture will play a critical role in addressing global challenges related to climate, water, social justice and food. These challenges cannot effectively be addressed in isolation. Instead, it is time to identify the interconnection between them and develop complementary policy options and action steps.”

EARTH2

“We humans with our big cars and our big factories and our big cities were discharging terrible stuff into the air and water, and it had to be stopped or we would soon make our nest uninhabitable. The public was growing increasingly outraged. Every night on color television, we saw yellow sludge flowing into blue rivers; every day as we drove to work, we saw black smudges against the barely visible blue sky. We knew that our indiscriminate use of pesticides and toxic substances was threatening wildlife and public health.”

“But we didn’t do much about it. Until 1970, most regulation of industry was done by the states, which competed so strongly for plants and jobs that regulating companies to protect public health was beyond them.

“Environmentally, it was a race to the bottom.”

Addressing the Global Water Crisis Through Action In Unity For Change

“By 2050, the population of the planet is projected to be 8.5 billion people. According to the work of Jim Thebaut, we will not be able to sustain ourselves if steps aren’t taken to ensure that water resources are available to people. The San Joaquin Valleyin California grows 1/3 of the agricultural crops that feed Americans. But, droughts are spreading across the Southwest on top of the drought that California is already experiencing. There is an undeniable strain on the world’s resources. This strain will grip the world community tighter if steps aren’t taken to combat climate change, the water crisis, and overpopulation.”

8 million tonnes of methane seeping out from Arctic annually: Study

“Methane, the second most common greenhouse gas from human activities after carbon dioxide, is bubbling out from the frozen Arctic much faster than expected and could stoke global warming, scientists have warned.”
