It's still raining in droughty California. Damn southern-highbush blueberries won't ripen. I only have a half-dozen artichokes. Should have way more!

South Africa's Western Cape declares drought disaster

South Africa's Western Cape province has declared a drought disaster as it faces its worst water shortage in 113 years.

Provincial leader Helen Zille said water will be harvested by drilling boreholes to serve key points like hospitals in Cape Town.

She also announced plans to use a mobile desalination plant and tap the natural aquifer under Cape Town's Table Mountain.

She also referred to desalination plants as being hailed as a possible alternative, but said there was no way it could be built to scale quickly enough to compensate for such a drought.

Residents have also been urged not to use no more than 100 litres (22 gallons) of water a day.

Southern African nations are reeling from a two-year drought.

Two reservoirs in the Western Cape region are already completely dry according to official statistics.

By Friday the dam levels were already at 21, 6% down from 70% in 2015 at the start of water restrictions. Kaiser said on the brink of winter when heavier rains are expected, meteorologists now warn this winter will be as dry as the previous two.

“Nothing can be taken for granted anymore,” she said and invited delegates to use water sparingly during their stay in the city.

The Karoo and West Coast areas of the Western Cape previously declared drought disasters in 2016, but Monday's announcement extends the scope of those emergency measures to the entire province, the AFP news agency reports.

The UN estimates that over 40 million people have been affected by the drought that was caused by the El Nino climate phenomenon.

Florida drought still 'extreme' (second to highest category in the scale).

Drought now spreading into the Dakotas, with a surrounding 'abnormally dry' area that extends into the northwest corner of my state, Minnesota.

Gotta get up early in the morning tomorrow to water my garden! :)

New weekly map just came out.

Florida got some relief, but the drought in the Dakotas and beyond has deepened and spread.

India's wells are running dry, fast

For the past 2,500 years, India has managed its water needs by increasing supply.

Prior to industrialisation and the accompanying global "green revolution" in the 1960s, which saw the development of high-yield variety crops using new technologies, India's water availability was plentiful. Households, industries and farmers freely extracted groundwater and dumped untreated waste into waterways without a second thought.

But such practices are now increasingly untenable in this rapidly growing country. Per capita availability of water has been steadily falling for over a decade, dropping from 1,816 cubic metres per person in 2001 to 1,545 cubic metres in 2011.

The decline is projected to deepen in coming years as the population grows. India, which currently has 1.3 billion people, is set to overtake China by 2022 and reach 1.7 billion in 2050.

For nearly 50 years, a misguided groundwater policy has sucked India dry; water tables have declined by an average of one metre every three years in some parts of the Indus basin, turning it into the second most over-stressed aquifer in the world, according to NASA.

Across nearly the whole country, basic sewage management is also lacking. According to the Third World Centre for Water Management, only about 10% of waste water in the country is collected and properly treated. As a result, all water bodies in and around urban centres are seriously polluted.

Even so, residents of New Delhi or Kolkata today use more than twice as much water, on average, than people in Singapore, Leipzig, Barcelona or Zaragoza, according to data compiled by the Third World Research Centre.

The water use in Delhi is 220 litres per capita per day (lpcd), while some European cities boast figures of 95 to 120 lpcd.

Excess consumption is attributable in part to citizen indifference about conserving water after so many years of plentiful supply. Since large swaths of many Indian megacities lack piped supply of clean water, leaks and theft are common. Cities in India lose 40% to 50% due to leakages and non-authorised connections.

And after millennia of exclusive focus on expanding the water supply, the idea of curbing water consumption and increase reuse remains a mostly alien concept in India.

... Water scarcity in Karnataka is aggravated by non-existent water quality management. Its rivers are choked with toxic pollutants, and oil-suffused lakes in Bengaluru, the capital, are reportedly catching fire. Meanwhile, in the northern part of the country, the Ravi-Beas River is causing conflict between Punjab and Haryana states.

In India's water wars, rivers are a resource to be harnessed and extracted for each riparian party's maximum benefit. Very little emphasis has been placed on conserving and protecting existing water sources. And not one inter-state negotiation has prioritised pollution abatement or demand management.

Between rapidly disappearing fresh water, unchecked pollution and so many thirsty citizens, India is facing an impending water crisis unlike anything prior generations have seen. If the nation does not begin aggressively conserving water, the faucets will run soon dry. There is simply no more supply to misuse.

Small climb in mean temperatures linked to far higher chance of deadly heat waves

An increase in mean temperature of 0.5 degrees Celsius over half a century may not seem all that serious, but it's enough to have more than doubled the probability of a heat wave killing in excess of 100 people in India, according to researchers at the University of California, Irvine and other institutions.

This could have grim implications for the future, because mean temperatures are projected to rise by 2.2 to 5.5 degrees Celsius by the end of this century in the low- and mid-latitude countries of the Asian subcontinent, the Middle East, Africa and South America.

Using data gathered by the India Meteorological Department from 1960 to 2009, the UCI-led team analyzed changes in summer temperatures; the frequency, severity and duration of heat waves; and heat-related deaths.

They found that when mean summer temperatures in the South Asia nation went from 27 to 27.5 degrees Celsius, the probability of a heat wave killing more than 100 people grew from 13 percent to 32 percent -- an increase of 146 percent.

In real terms, there were only 43 and 34 heat-related fatalities in 1975 and 1976, respectively, when the mean summer temperature was about 27.4 degrees Celsius. However, at least 1,600 people died from excessive heat in 1998, when the mean summer temperature was higher than 28 degrees Celsius.

The average number of heat wave days over the five-decade study period was 7.3 per year. The most heat wave days occurred in 1998 (18), when 1,655 people died, and 2003 (13), when 1,500 people died.

Drought conditions in the Dakotas and Northern Montana are worsening fast, threatening wheat crops.

http://droughtmonitor.unl.edu/

Bloomberg: “The wheat varieties that trade on U.S. commodity exchanges are diverging sharply in price. Spring wheat is fetching a growing premium to the winter classes grown in the Great Plains and Midwest, with the spread against hard red winter wheat futures reaching a nine-year high. That’s because the spring crop, which still has several weeks left to develop, is in poor shape as drought conditions persist in northern states.”

From Eric Holthaus (sciencebyericholthau newsletter) today:

“There’s a quickly worsening drought right now in the upper Midwest. In just the last week, “extreme” drought expanded from 7.7 percent to 25.1 percent of North Dakota, the hardest-hit state. And next week, a multi-day heat wave is on the way. It’s expected to reach as high as 107 degrees Fahrenheit in parts of the Dakotas, more than 20 degrees above normal.

Why does that matter? For one, it might seriously affect this year’s wheat harvest there.

Wheat is humanity’s most important grain food source, the United States is the world’s largest wheat exporter, and the Dakotas and Montana are now the most important wheat growing region of the United States. Wheat prices have already gone up more than 10 percent in just the past few weeks in response to the drought. This year’s American wheat crop is currently rated the worst in 29 years..."

As lakes run dry in Chennai, residents are desperate for a few buckets of water.

Desperate search for water

Even before the onset of summer, it was anticipated that there would be great difficulty in maintaining regular water supply to Chennai. When water levels in the four lakes fall, MetroWater usually taps into the Veeranam lake in Cuddalore district to make up for the shortfall. But this large lake has also run dry. This prompted MetroWater officials to extract water from the Wallajah lake, also in Cuddalore. But the use of these rural lakes to meet urban needs has infuriated farmers in the district, who say they are being deprived of their water resources.

“We have lived by this lake for decades,” M Anbazhagan, a farmer, told Scroll.in on May 1. “We were not even consulted or informed about our water being directed to Chennai.”
