Water scarcity issues expected to escalate rapidly across Scotland

Water scarcity across Scotland is expected to escalate quickly, the nation's environment agency has warned.

With little rain forecast in the next few weeks, most of the country has been put on early warning.

The Scottish Environment Protection Agency (Sepa) said the issue was most acute around Loch Maree in Wester Ross.

However, large parts of north west and southern and central Scotland have also been raised to alert status after a spell of warm, dry weather.

Sepa issues water scarcity reports every week throughout the summer months.

The latest one shows only one small section of the north east of Scotland in normal conditions.

...

Farmers and golf courses have been asked to only use the water they need especially if taking it from small burns or rivers.

After a very wet start of the year in the Netherlands it has been sunny all May and it will continue for the first half of the month so the drought deficit is growing also helped by dry strong winds which dry out soils. Soon it will be 30 degrees and more water will be used for irrigation.

We should hit 140mm soon which is worse then 2018 and 2022 which are the worst years this century.

Introducing Super Drought: A New Framework and Web Service
https://phys.org/news/2023-06-super-drought-framework-web.html


https://superdrought.com/

In recent years, the world has witnessed an alarming increase in the occurrence and severity of catastrophic droughts across various regions. While extensive research has been dedicated to understanding extreme droughts, a fundamental question has remained overlooked: What truly defines an extreme drought? Unraveling this complex phenomenon requires addressing its multi-scalar nature.

Taking on this challenge, Dr. Lin Wang from the Institute of Atmospheric Physics at the Chinese Academy of Sciences introduces the concept of "super drought." This theoretical framework, published in Bulletin of the American Meteorological Society, highlights the simultaneous occurrence of extreme droughts at multiple time scales, shedding light on the compound dry extremes that impact water resources and result in significant water storage loss.

It acts as a vital differentiator, separating high-impact droughts from those with milder consequences.

... Recognizing the importance of international collaboration, Dr. Wang is committed to enhancing China's influence in the field of drought index and monitoring. In pursuit of global accessibility, he has launched the web service, https://superdrought.com/ . This platform provides near-real-time monitoring of global super drought events, enabling users to stay informed about the latest developments. Additionally, the website serves as a comprehensive historical data repository, offering invaluable insights to researchers, policymakers, and interested individuals.

"At superdrought.com, our utmost priorities are transparency and accessibility," Dr. Wang emphasizes. Through this public website, end users and decision-makers can effortlessly access both near-real-time monitoring data and an extensive historical data archive.

I previously quoted a study that showed that during the Holocene Optimum when there might have been even less (or the same) Arctic Ice than now, the Scandinavian High seems to have been quite prevalent during summers. This creates warm and dry conditions over N.Europe and the British isles and cloudier, cooler and wetter conditions in C and S. Europe.

This year we've been having a quite persistent Scandinavian high for a good many weeks and this - if the above study is right - might become the norm during the next decades...so get some sprinklers and sunscreens you white skinned Northern folks :)

Unfortunately sprinklers have been banned (with a potential £1000 fine) here in sunny South West England since last summer.

In an unlikely turn of events I have recently been interviewed by the Daily Torygraph on such matters:

Extremely dry spring leaves southern Albertan farmers on the road to ‘zero production’
Quote
Crops in southern Alberta that should be green are turning brown. With little to no measurable precipitation since mid-April in areas south of Calgary,  some farmers are already predicting crop losses.

According to the June 6 Agricultural Moisture Situation update a warm, dry fall and spring has failed to recharge soil moisture leaving many areas facing once in 50-year lows for this time of year.

“They are dying essentially. It’s something that we’ve never experienced before. We’ve had dry conditions later in the season but to have it at the end of May, beginning of June like this is unprecedented,” said Stephen Vandervalk, a fourth generation farmer in southern Alberta and the vice president of the Western Canadian Wheat Growers Association.

“We are out a third of our crop as of today, for sure, and every single day it’s just nose diving. Every day now we are probably losing 5 per cent of our yields, so if we don’t get rain for another week, then half a crop, maybe, is in the cards,” Vandervalk said.

Adding to the problem: grasshopper infiltration.

“We are trying to spot spray areas because otherwise what happens (is) you will lose your entire crop. Zero. Bare to the ground,” Vandervalk said.

He added the only thing saving Alberta now from the catastrophe the province experienced in the 1930s is better farming practices.

“Farming techniques have changed so much that if we were experiencing what we have in the last six years, 30 or 40 years ago, southern Alberta would be a dust bowl,” Vandervalk said.

“For the lack of a better term, we are on the road to zero production here in this area south of Calgary to about Fort Macleod.”

The reeve of Foothills County says a lot of ranchers are not turning their cattle out to pasture because there isn’t a lot of grass out there.  That means the cattle are still feeding from winter storage.

“Once those start to be depleted, which I’m hearing they’re getting close, they will either be buying feed or looking for other pastures because in this area, we’re certainly not seeing a lot of grass,” said Delilah Miller on Sunday in High River.

Spain drought forces Fuente de Piedra flamingos to find new home

A protracted drought in Spain's renowned southern wetlands has forced flamingos to hatch chicks elsewhere.

The Fuente de Piedra wetlands in the Malaga province were declared a natural reserve in 1984. But on Saturday, only a few dozen adult birds could be seen in the saltwater lagoon.

By mid-May, Spain had received 28% less rain than expected, officials said.

It has seen its hottest spring since 1961, with high temperatures likely to continue throughout the summer.

Previously more than 200,000 flamingo chicks have hatched at the lagoon, according to Andalusia's Agriculture office.

Local resident Alberto Gonzalez Sanchez said this was due to climate change.

"It is a shame because of the tourism, people come here for the day," Mr Sanchez said.

Uttar Pradesh: Row over claims of heatwave deaths in India state


Officials in the northern Indian state of Uttar Pradesh are investigating dozens of deaths that some have attributed to a heatwave.

Between Thursday and Sunday, 68 deaths were reported in Ballia district, around 274km (170 miles) from state capital Lucknow.

A district health official who said earlier that heat could be a cause was transferred, sparking a political row.

The state government later set up a panel to submit a report on the deaths.

Temperatures in several parts of Uttar Pradesh have ranged between 42C and 47C in the past week. The government has advised elderly people to stay indoors.

In neighbouring Bihar state, local media reported that more than 40 people had died due to heat since 31 May, but state officials denied this.

Dr Umesh Kumar, the official in charge of Bihar's disaster control room, told the BBC that they had only established one report of death due to extreme heat, in Jehanabad district.

The controversy in Uttar Pradesh began on Friday after Diwakar Singh, chief of Ballia district hospital, told reporters that around 25 people had died, and that heat may have been a factor.

"Most of the patients were above 60 and had pre-existing ailments. These were exacerbated by the heat and they were brought to the hospital in serious condition. They died despite being given adequate treatment and medicines," Dr Singh said.

A day later, he was transferred from the post. Brajesh Pathak, the state's deputy chief minister, said that Dr Singh's statement was "careless" but added that the government was taking the situation "very seriously".

Current Level of Rainfall Recharging Groundwater In Southwest Australia at Its Lowest for the Last 800 Years: Study
https://phys.org/news/2023-06-current-rainfall-recharging-groundwater-southwest.html



In a world-first study, Australian environmental scientists have used cave stalagmites as a record of groundwater replenishment over time, that showed the current level of rainfall recharging groundwater in southwest WA is at its lowest for at least the last 800 years.

The evidence indicated that there has been a decline in rainfall recharge to groundwater in southwest Australia over the last 20 years due to reduced rainfall.

This scientific development was achieved by using stalagmites and ceiling dripwater from caves that are located between the land surface and the groundwater table. The research has been published in Communications Earth & Environment.

... "We are now working towards extending the record to 10,000 years ago, to understand when groundwater was recharged and under what past climate scenarios this occurred.

... Dr. Pauline Treble explained that the Southwest Australia region is dependent on groundwater to meet approximately 75% of its water demand. "The research highlights the vulnerability of this resource," Dr. Treble said.

Uruguay Drought: Capital Hit By Water Shortages
https://www.dw.com/en/uruguay-drought-capital-montevideo-hit-by-water-shortages/a-66075991

Montevideo is experiencing its worst drought in over 70 years. The situation is being worsened by locals hoarding water supplies.

... Montevideo, a metropolis of 1.3 million people, and the greater metropolitan area, where more than half of Uruguay's population live, is slowly running out of drinking water. Its most important water source, the Paso Severino reservoir located north of Montevideo, is nearly completely empty and currently only holds 3% of its normal capacity.

In Montevideo, which once boasted some of the best municipal water in South America, not even 50% of households open their taps anymore, surveys show. The reason is that anyone who takes a sip will likely feel like they are drinking water from the Atlantic Ocean. The pitiful remains from the reservoir have been mixed with water from the pesticide-contaminated River Plate. River and seawater mix in the estuary of the Rio Parana and Rio Uruguay streams, leading to an increased chlorine and salt content in Montevideo's municipal water, far exceeding World Health Organization thresholds.

Uruguay's water emergency has therefore escalated into a political crisis, sparking street protests. Environmental protection group Redes - Amigos de la Tierra blames the dire situation on "plundering." It says that cellulose factories, rice-growing companies and soy farmers consume vast amounts of water without having to pay a single peso.

"Almost 80% of our freshwater goes to the agricultural and forestry sector, so we can certainly say water resource exploitation is very high in Uruguay," says Meerhoff. "Because so much water is used in industry, the amount for water for personal use and nature is obviously very limited."

"What is happening here in Montevideo can happen in any city in the world," says environmental expert Meerhoff. "It has happened before a few years ago in Cape Town, South Africa, and Curitiba, Brazil when extreme drought left people without drinking water — with climate change, such scenarios are becoming more and more likely around the world."

‘This is going to get worse before it gets better’: Panama Canal pileup due to drought reaches 154 vessels

The number of vessels waiting to cross the Panama Canal has reached 154, and slots for carriers to book passage are being reduced in an effort to manage congestion caused by ongoing drought conditions that have roiled the major shipping gateway since the spring. The current wait time to cross the canal is now around 21 days.

The Panama Canal is a critical trade link for U.S. shippers heading to Gulf and East Coast ports. The U.S. is the largest user of the Panama Canal, with total U.S. commodity export and import containers representing about 73% of Panama Canal traffic. Forty percent of all U.S. container traffic travels through the canal every year, about $270 billion in cargo.

The massive pileup is a result of water conservation measures the Panama Canal Authority deployed in late July due to drought. The PCA has temporarily lowered the availability of booking slots from August 8-August 21 for Panamax vessels, which are the largest vessels that can cross the canal. These vessels can carry 4,500 twenty-foot equivalent units (TEUs), which are the dimensions of a container. The number of pre-booking slots was reduced to 14 daily from 23....

...Additional lower water level restrictions imposed by the PCA in July also require vessels to be 40% lighter, impacting vessels that were in transit when the requirements were implemented. The Ever Max was forced to unload 1,400 TEUs at the Port of Balboa in order to meet the requirements and gain passage. The vessel is currently anchored at the Port of Savannah.

“Those containers left may need another vessel to complete the journey,” said Captain Adil Ashiq, head of North America for MarineTraffic. “This is going to get worse before it gets better,” he said....

One thing that will become a problem is rivers drying out so less and less bulk cargo can be transported but this is the same thing.

Suffolk water shortage may 'throttle back' firms' growth

A water shortage in an area of Suffolk has led to some firms being refused permission to set up or told they could not expand, the BBC has learned.

The policy by Essex & Suffolk Water (ESW) has affected those using large volumes of water like manufacturers, farmers and food processors.

A leading councillor said they could be "throttled back" from expanding.

ESW said there was enough water for current needs and new housing, but not for business growth.

The company's policy, which has been in place for about 12 months, has affected an area around the town of Eye in Suffolk, known as the Hartismere Water Resource Zone.

It has been put in place until 2032, when new water supply schemes in Hartismere should be operational.

Andrew Stringer, the senior councillor who oversees planning in Mid Suffolk, said the policy was "quite scary" but "no surprise at all".

"We have for decades been choosing economic growth above the needs and resources of our planet and this is a stark – very stark – consequence of that," said Mr Stringer, Green Party.

"You simply cannot continually economically grow beyond the ability of our planet to sustain."

Mr Stringer said the policy could "throttle back a lot of businesses that want to expand". He added Mid Suffolk was "absolutely not closed for business" but was "open for sustainable business".

"It's worrying, of course, because you want businesses to thrive, but equally it's a chance for us to re-look at the policies and make sure we do take water use deadly seriously."

Sorry if you are confused by the posts on different topics, I cover multiple issues with different posts--not all, even on the same general topic "Drought" are about the same place, event or issue.

The map is of North America, traditionally defined as Canada, USA and Mexico.

Those countries south of there are part of Central America and the Caribbean--Panama, where the Panama Canal is is part of Central America  (but it has a very Caribbean culture).

Even further south, just south of Panama, is the South American continent.

I hope that clarifies the issue for you

As many  as 25 countries or a quarter of the world’s population are currently exposed to extremely high water stress annually, new data from World Resources Institute (WRI) Aqueduct Water Risk Atlas showed.

This means they use over 80 per cent of their renewable water supply for irrigation, livestock, industry and domestic needs. Even a short-term drought puts these places in danger of running out of water and sometimes prompting governments to shut off the taps.

Globally, at least 50 per cent of the world’s population — around four billion people — live under highly water stressed conditions for at least one month of the year, the WRI report noted. And by 2050, that number could be closer to 60 per cent.

A region is said to be under ‘water stress’ when the demand for water exceeds the available volume or when poor quality restricts use.

The 25 most water-stressed countries are: Bahrain, Cyprus, Kuwait, Lebanon, Oman, Qatar, the United Arab Emirates, Saudi Arabia, Israel, Egypt, Libya, Yemen, Botswana, Iran, Jordan, Chile, San Marino, Belgium, Greece, Tunisia, Namibia, South Africa, Iraq, India and Syria.

The most water-stressed regions are West Asia and North Africa, where 83 per cent of the population is exposed to extremely high water stress and South Asia, where 74 per cent is exposed.

Global water demand is projected to increase by 20-25 per cent by 2050, while the number of watersheds facing high year-on-year variability, or less predictable water supplies, is expected to increase by 19 per cent. For West Asia and North Africa, this means 100 per cent of the population will live with extremely high water stress by 2050.

This is an issue of concern not just for consumers and water-reliant industries, but for political stability, according to the authors of the WRI report.

The biggest change in water demand between now and 2050 will occur in sub-Saharan Africa, they added. “While most countries in sub-Saharan Africa are not extremely water-stressed right now, demand is growing faster there than any other region in the world.”

By 2050, water demand in sub-Saharan Africa is expected to skyrocket by 163 per cent — four times the rate of change compared to Latin America — the second-highest region which is expected to see a 43 per cent increase in water demand, the analysts observed.

This increase in water use, mainly expected for irrigation and domestic water supply, could foster major economic growth in Africa — projected to be the fastest-growing economic region in the world, they noted.

However, inefficient water use and unsustainable water management also threatens to lower the region’s gross domestic product (GDP) by 6 per cent, according to WRI’s Water Risk Atlas.

Once again, in case you didn't understand, Gatun Lake is not in the geographic limits of "North America" of the drought map---it is in Central America in the country of Panama, where the "Panama Canal" is located.  For your refence, Gatun Lake is toward the center of the larger scale map.  Note the inset map that shows where Panama is in what is called "Central America" not "North America"

I understood perfectly.  Lake Gatun is not in the North America drought map.  I do not understand why we are talking about it within that context.

Planning for a future of a less usable Panama Canal

Drought-hit Panama Canal to restrict access for one year

Panama City (AFP) – The drought-hit Panama Canal will maintain restrictions on the passage of ships for one year, a measure that has already led to a marine traffic jam as boats line up to enter the waterway linking two oceans.


Some 130 boats are backed up waiting to enter the Panama Canal, compared to around 90 usually in the queue

The canal is facing a shortage of rainwater needed to transfer ships through locks that function like water elevators, an engineering marvel that moves six percent of the world's maritime commerce up and over the isthmus between the Atlantic and Pacific oceans.

The canal's sub-administrator Ilya Espino, told AFP that unless heavy rains fall in the next three months, "we are looking at a period of one year" of restricted access.

That period will give clients "a year to plan" how to adapt, she said late Thursday.


Each ship moving through the canal requires 200 million liters of freshwater to move it through the locks, provided by two artificial lakes fed by rainfall in a surrounding watershed. The lakes also supply drinking water to half the country of about 4.2 million people.

However, Panama is facing a biting drought, made worse by the El Nino warming phenomenon, which has forced canal administrators to restrict the waterway to ships with a maximum draft (water depth) of 13.11 meters (43 feet).

In 2022, an average of 40 ships crossed through the canal a day, a number which has now dropped to 32 to save water.

When writing of three Americas, North, South and Central, Panama is in "Central."  But when writing of Western Hemisphere continents, there are two: North and South, and Panama is in "North."  Here's Wikipedia's map.

Hmm, the entire North vs Central controversy stems from the Walrus' confusion as why I posted an article about the Panama canal situation, and then I posted the North American drought map which does not include Panama.

He seemed to think that I was dealing with the same issue in 2 different unlinked posts, but one post was on the Panama canal, and the other related to current drought consitions in Canada, USA and Mexico as illustrated in a map prepared by University of Nebraska in Lincoln (UNL).

Once again, for the record, 2 unrelated posts that fall under the general topic of drought.

If you wish to discuss the falsity of titling or the incompleteness of UNL's map, you should send them an email.  I'm sure they'll be eager to discuss it with you.

All the evidence is here so scroll back to reply 165 615 so we can be done with the side discussion.

Anyway with a year of closure that will be more ships going the long way.

You posted a NA drought map to which Walrus replied that the drought expanse is the lowest since 2020, to which you replied something about Gatun Lake, Panama which has absolutely no connection to what you posted or what Walrus said. Then you lectured him about geography.


It's like you saying: the sky is very blue today, to which walrus said: but it was bluer yesterday, to which you would reply: the lake is very blue, to which Walrus replies: We are not even talking about the lake, and then you go: let me explain you the difference between the sky and the lake.

Seriously, it's quite childish and totally OT.

increased reliance on water intensive cash crops are threatening the life of aquifers in an already drought intensive environment...aquifer drops of up to 5m

Abstract
In recent years, semi-arid regions of India, especially Marathwada, have been continuously under the grip of drought. Increasing water scarcity and depleting ground water levels have accentuated the agrarian crisis with an increased number of farmers committing suicide in this region. To understand this issue, the present paper deals with the roots of the drought severities concerning the summer monsoon rainfall and changing crop types over the districts of the Marathwada region, India, from 1996 to 2018. In this study, drought severities were quantified using station-based rainfall, groundwater level, and crop data (10 most cultivated crops) collected from various national agencies. The increasing rainfall trends over the Latur, Beed, and Aurangabad districts depict positive signs for agriculture. In contrast, other districts were under decreasing rainfall trends, but these declining rates were not statistically significant. The alarming fall of ground water level from 4 to 5 m during the considered period was noticed over most of the region, which is a cause for concern. The significant changes in agricultural practices from low-water-requirement crops such millet (bajra), sorghum (jowar), and wheat to high-water-requirement crops such as sugarcane and cotton were observed over Beed, Latur, Osmanabad, and Parbhani. An increase in the yield of cash crops demands an augmented water supply, which is becoming responsible for the rapidly declining ground water level. Therefore, this study claims that more than rainfall vagaries, the severe impact of droughts is a reflection of changing agricultural practices and poor management of water resources.

Colombia Mulls Future of Massive Coal Mine As Water Dries Up
https://phys.org/news/2023-09-colombia-mulls-future-massive-coal.html

Colombia's massive El Cerrejon coal mine has landed in the crosshairs of President Gustavo Petro, who has blamed the open-pit operation for plunging the local Indigenous community into a severe water crisis.

Gigantic black craters scar the earth in La Guajira, northern Colombia, after four decades of coal extraction that has sucked up large quantities of water in an already-arid region hit by a wave of extreme droughts.

The leftist leader Petro, who has championed environmental concerns, in July declared an "economic, social and ecological emergency" in La Guajira, where poverty levels are at 67 percent, and dozens of children die every year from malnutrition.

In August, during a visit by Switzerland's president, Petro said he was looking for a "coordinated exit" by Glencore, the Swiss commodities giant which owns the mine.

Petro has said that much of the region's scarce water supplies are now being monopolized by the "agriculture, energy, and coal" industries.

Water Shortage Drives Elephant Migration From Zimbabwe
https://phys.org/news/2023-09-shortage-elephant-migration-zimbabwe.html

Large numbers of elephants from Zimbabwe's biggest national park are moving to neighboring Botswana in a search for water, a spokesman said Monday. "Many animals have and are moving from Hwange National Park into Botswana" Zimbabwe Parks and Wildlife Management Authority spokesman Tinashe Farawo told AFP.

"Water bodies have dried up and the animals are in search for water and food," the spokesman said, adding that buffaloes and "all types of animals present in the park" were also migrating in scores.

"I can't quantify how many elephants have moved whether its hundreds or thousands but it has been a lot," he said of the migration which began in August. "The amount of animals migrating has definitely increased over the years due to the increase in water shortages," Farawo added.

The mass movement of wild animals could lead to an increase in conflict between humans and wildlife as they pass through populated areas in Zimbabwe. "It means more animals are going to invade communities, people competing for water with animals," Farawo warned.

'It's an Emergency.' Midwest Towns Scramble As Drought Threatens Drinking Water
https://phys.org/news/2023-09-emergency-midwest-towns-scramble-drought.html

... "I just can't make it rain," ...

Like others across Southeast Kansas, Rainbolt remains helpless as he watches a persistent drought dry up the local water supply. He runs a public wholesale water supply district that provides the drinking water for several cities and rural water districts. The lack of rain has been so severe that it's now threatening the water district's intake pipe, which brings water from a local lake to the treatment plant.

As lake levels fall, the angle at which the 8-inch pipe meets a floating pump station grows steeper and steeper, stressing the flexible joint. If the joint breaks, the consequences would be catastrophic, instantly cutting the water supply for thousands of people, businesses and schools across three counties.

"If we break it, we have no water. Period," said Jack Warren, the mayor of Sedan, Kansas, a county seat about 100 miles southeast of Wichita and the largest customer of the water district.



This part of Kansas is suffering what the U.S. Drought Monitor characterizes as exceptional drought, its most severe category. While droughts frequently wreak havoc on agriculture here, residents are facing unprecedented challenges with drinking water supplies. This corner of the state, which lacks the vast underground aquifers that sit below much of Kansas, is overly reliant on surface water such as lakes and rivers.

That means small towns and ranches face tough and expensive choices on where to draw water from, a problem likely to increase as climate change brings more extreme weather. And it's a quandary that stretches far beyond Kansas. Persistent drought is plaguing communities across the country's interior: The map created by the U.S. Drought Monitor shows its deepest red pockets across Iowa, Kansas, Louisiana, Minnesota, Missouri, Nebraska and Texas, among other states.

Lack of rain has hit crops hard: In Missouri, for example, 40% of the state's corn crop was classified as poor or very poor, according to the drought monitor. Iowa, the nation's top corn producer, is in the midst of its worst drought in a decade with about 80% of the state in some measure of drought.

Prolonged drought has even reached the banks of Lake Superior: Parts of Wisconsin have the most severe drought designation for the first time since the 1999 inception of the U.S. Drought Monitor, said Dennis Todey, director of the U.S. Department of Agriculture's Midwest Climate Hub.

"It's the severity of the drought and the length of the drought that are causing some confounding issues right now," he said.

Locals, who noted that the drought has been ongoing since last year, said they've never seen a situation this severe.

"It just doesn't rain," said Rainbolt, who has lived in the area for nearly two decades. "This is not normal." (... it is now)

... On average, the town sees nearly 40 inches of precipitation each year, according to National Weather Service data. But last year, Sedan reported only 28.32 inches. Through August of this year, the town has seen fewer than 18 inches.

... "Soybeans are burning up in the field, the grass is burning up on the prairie. And water's becoming a bigger and bigger issue," he said. "Something needs to happen pretty quick."

... The drought has threatened hay production, a necessity to keep livestock fed through cold Kansas winters. Bell said many ranchers, including himself, have culled their herds because of limited water and hay.

BRASILIA, Sept 27 (Reuters) - Brazil's government is preparing a task force to provide emergency assistance to inhabitants in the Amazon region hit by a severe drought that has impacted the rivers that are their life support, Environment Minister Marina Silva said.

Low river levels and hotter waters have killed masses of fish seen floating on river surfaces, contaminating the drinking water, she said.

"We have a very worrying situation. This record drought has disrupted river transport routes threatening food and water shortages, and a large fish mortality is already beginning," she told Reuters in an interview.

Some 111,000 people have been affected in a region where a much of the population's protein comes from fishing, which will be suspended for some time, she added.

The civil defense agency warned that the drought could eventually impact up to 500,000 people in the Amazon.

The Port of Manaus website said the Rio Negro's water level fell by an average of 30 centimeters (11.8 inches) a day since mid-September and stood at 16.4 meters (54 feet) on Wednesday, about six meters below its level on the same day of last year.

The federal task force would be airlifted by the Air Force to the states of Amazonas and Acre with water, food, medicines and other resources, Silva said.

The government also allocated 140 million reais ($27.76 million) to dredging rivers and ports in the region to keep transport flowing when water levels drop, she added.

The drought in the Amazon, like the flooding in the south of Brazil, results from the El Niño phenomenon, which warms the surface water in the Pacific Ocean. This year the impact has been greater than normal, weather experts say.

'It's an Emergency.' Midwest Towns Scramble As Drought Threatens Drinking Water
https://phys.org/news/2023-09-emergency-midwest-towns-scramble-drought.html



Western and SW Kansas is headed toward a non-irrigated agricultural(?) future--2 feet of aquifer fall per drought year

Average groundwater levels across western and south-central Kansas fell by nearly 2 feet in 2022, according to preliminary data compiled by the Kansas Geological Survey.

2023 water level changes, via Kansas Geological Survey.The KGS, based at the University of Kansas, and the Division of Water Resources (DWR) of the Kansas Department of Agriculture measure about 1,400 wells every year to monitor the health of the High Plains aquifer and other aquifers in western and south-central Kansas. Those measurements showed an overall average decline of 1.89 feet last year.

Most parts of the region saw well-below-average precipitation throughout the year. Some areas in Kansas were the driest ever based on historical records, some of which go back to the late 1800s. Dry years lead to increased pumping demands, primarily for irrigation, which in turn typically cause greater declines in water levels.

“We anticipated and saw declines pretty much across the aquifer,” said Brownie Wilson, KGS water-data manager. “Because of the ongoing drought, the pumping season lasted a little longer this past year, and there were a notable number of wells pumping in January and February. As such, some of the measured declines will likely be slightly excessive given the aquifer didn’t have its normal time to recover.”

The overall average decline of 1.89 feet in 2022 is the third largest in 25 years, on a par with the last notable dry years of 2011 (when water levels fell 1.93 feet) and 2012 (a decline of 2.01 feet). It also marked the third straight year of overall declines. Overall levels fell 1 foot in 2021 and 0.89 feet in 2020. Both 2020 and 2021 were abnormally dry years.

At the end of 2022, all 105 counties in Kansas were under a drought watch, warning or emergency status. As of the end of February, the western and southern parts of the state covered by the groundwater monitoring program were experiencing severe to exceptional drought, according to U.S. Drought Monitor maps produced by the National Drought Mitigation Center at the University of Nebraska-Lincoln, the U.S. Department of Agriculture and the National Oceanic and Atmospheric Administration.

The High Plains aquifer is a network of water-bearing rock that extends into eight states. In Kansas, the aquifer comprises three components — the Ogallala aquifer, the Great Bend Prairie aquifer and the Equus Beds. Of these, the Ogallala aquifer underlies most of western Kansas and consists mainly of the Ogallala Formation, a geologic unit that formed from sediment eroded off the uplifting Rocky Mountains.

Most of the wells in the network monitored by the KGS and DWR are within the boundaries of the state's five Groundwater Management Districts (GMDs), which are organized and governed by area landowners and local water users to address water-resources issues.

In Southwest Kansas GMD 3, average groundwater levels dropped 2.77 feet in 2022, following declines of 2.08 feet in 2021 and 1.25 feet in 2020. The region experienced the most severe drought conditions in the state in 2022, with widespread areas receiving 50 to 75 percent of long-term precipitation averages.

“Precipitation, or the lack thereof this year, is just one variable that goes into water-level changes,” said Wilson. “Soil types, evaporation, water availability and a variety of aquifer conditions are all key factors in how water is used across our state. Southwest Kansas

Australia Records Driest-Ever Month
http://www.bom.gov.au/clim_data/IDCKGC1AR0/202309.summary.shtml

September was Australia’s driest month since records began with a national average rainfall of just 4.83mm.

To find the second driest month since records began in 1900 we have to go back to April 1902 when a national average of 4.88mm was recorded.

The Bureau of Meteorology said September was dominated by high pressure systems which brought settled weather conditions and cloudless skies for most of the country. Combined with a positive Indian Ocean dipole, the recently declared El Niño and the long-term influence of climate change, that meant total rainfall was 70.8% below the long-term average for September.

The national mean temperature was also 2.43C above average, making the past month Australia’s third warmest September on record.

In some states, those temperatures pushed higher still. Western Australia recorded its warmest September on record and New South Wales and Victoria their second warmest. Those three states also recorded their hottest September days on record.

The mean maximum temperature nationally was 3.38C above average, the second highest on record for the month of September.

The influence of El Niño and a positive Indian Ocean dipole means the long term Spring outlook for most of the country is for below median rainfall and above median maximum temperatures.

Actual evapotranspiration plays a dominant role in drought of central Asia: Study

The Central Asian region is sensitive to global climate change and prone to drought. A research team led by Prof. Hao Xingming from the Xinjiang Institute of Ecology and Geography, Chinese Academy of Sciences, has found that actual evapotranspiration plays a significant role in drought of Central Asia.

Droughts in Central Asia intensified between 2000 and 2020, primarily in agricultural and hydrological droughts, and increase in actual evapotranspiration exacerbated and dominated both droughts to varying degrees.

This work was published in Remote Sensing on Sept. 16.

Precipitation, soil moisture, terrestrial water storage and total lake area in Central Asia showed decreasing trends during the study period, with a significant increase in agricultural and hydrological drought and a slight increase in meteorological drought. The trends and characteristics of different types of droughts exhibited significant differences in spatial-temporal distribution.

Compared to precipitation and runoff, actual evapotranspiration played a dominant role in agricultural and hydrological drought in Central Asia, with contributions of 64.38 and 51.04 percent, respectively.

https://phys.org/news/2023-10-mighty-mississippi-america-highway-dangerously.html



Chart showing monthly water levels of the Mississippi River at Memphis, Tennessee from 2014-2023.

... For farmers in the vast US Midwest, the Mississippi is an indispensable part of their transportation network.

But drought has left the river narrower and shallower, limiting shipping capabilities.

The bottleneck is ill-timed: early autumn is when farmers are working flat out to harvest soybeans and corn. With river shipping limited, they scramble to deal with massive buildups of stocks.

On the river in Osceola, Arkansas, Jeff Worsham manages an agricultural port. But two of its three docks are unusable due to the low water.

A barge is tied up at the only accessible dock as soybeans are shot from a huge metal spout into its hold.

The vessel's capacity equals that of roughly 80 trucks—but for now, it can only be filled to 50 or 60 percent capacity so the craft does not run the risk of getting stuck in the mud.

... The overriding fear is that the water crisis will become the new normal.

Last year, a record that had stood since 1988 was broken. It was broken again this September, and yet again in October.

A drought that began last year in the Mississippi's vast watershed (covering 40 percent of the continental United States) "lingered into this year, and it's gotten worse," Anna Wolverton, a National Weather Service specialist, told AFP.

Drought-Hit Farmers In US Heartland Hope Mississippi 'Comes Back'

There are 3 classes of people: those who see. Those who see when they are shown. Those who do not see

Insensible before the wave so soon released by callous fate. Affected most, they understand the least, and understanding, when it comes, invariably arrives too late

Ancient Human Faces Emerge in The Amazon as Extreme Drought Grips

An extreme drought in parts of the Amazon has led to a dramatic drop in river water levels, exposing dozens of usually submerged rock formations with carvings of human forms that may date back some 2,000 years.

Manaus reaches its boiling point

...

In Manaus, the Rio Negro is flowing at its lowest level in 121 years, while some stretches of the Rio Solimões, previously crossed by countless boats, have now become sandy deserts. In Lake Tefé, in the Médio Rio Solimões region, more than 140 Amazonian dolphins have died. Their deaths seem to have been caused, at least in part, by heat stress caused by water temperatures near 40 degrees Celsius, compared to a maximum average of 32 degrees. But rivers and igarapés, the small tributary streams of the Amazon River – whose level is dropping by 13-14 centimeters a day – are disappearing everywhere, dramatically transforming the Amazonian landscape.

It’s not the first time this has happened. Between 2015 and 2016, El Niño, the periodic climatic phenomenon linked to a strong warming of the waters of the tropical Pacific, had caused dramatic effects; but this time everything seems to be amplified, due on one hand to global warming and to deforestation and fires on the other (which are also favored by the drought). In September alone, 6,991 fires were recorded, the second-highest number ever (beaten only by the same period in 2022, with 8,659 fires).

Even worse: according to forecasts, the drought will not ease up until at least December (but more likely until early next year), when El Niño will peak. This will have devastating consequences for both aquatic and terrestrial fauna and flora. In short, if there is one region where one can see most clearly the effects of the “boiling climate,” it’s the Amazon.

This is an environmental, social and economic catastrophe all at once. In the state of Rondônia, the Santo Antônio hydroelectric power plant, the fourth largest in the country, had to suspend its operations – something that only ever happened once – because of the low flow of the Madeira River, which is 50 percent lower than the historical average. In 79 municipalities in Pará and Roraima, the drought has also affected areas used for agriculture and livestock, and a state of emergency has been declared since September 30 in 55 out of 62 municipalities in Amazonas state.

And, while hundreds of communities that lived off sustainable fishing of pirarucu and tambaqui have already lost their main source of livelihood, 35 large industrial plants in Manaus have sent 17,000 workers on furlough until November 4 due to the low navigability of Amazon rivers, which prevents the arrival of needed supplies. Even more, some 500,000 people are expected to be left without access to drinking water (as indigenous communities often use what little water they have to put out the fires), as well as food: not only because the large boats transporting food from Manaus to the interior of the state can no longer navigate the Solimões river, but also because the scarcity of resources is causing rising prices for various consumer goods.

And further implications...

An Extreme Weather Event in 2014-2016 Sped Up Sea-Level Rise, Study Finds

...

Two consecutive El Niño events in 2014-2015 and 2015-2016 coincided with the 15-millimeter rise in global mean sea levels. The 2015-2016 El Niño event was particularly extreme, with 2016 quickly surpassing 2015 as the hottest year on record, according to the World Meteorological Organization (WMO).

"Those unusual El Niño events affected the precipitation pattern worldwide, decreasing the terrestrial water storage in the Amazon basin and therefore leading to an increase of the global mean ocean mass," William Llovel and colleagues explain in their paper.

2015/6 is the first time we see this extra contribution to SLR and we might see it again.

Things in the Amazon will get pretty bad.

California is completely drought-free statewide for the first time in over 3 years.
Incredible.

Meanwhile, the southeast US is suffering from a flash drought, due to the jet stream maintaining a position preventing the usual weather fronts from crossing the region.
People who say it cannot be done should not interrupt those who are doing it.

Some data visualizations of the Amazon drought. Absolutely terrible, huge swathes are in the worst drought in 50 years. And while this year is exceptional, it's also part of a clear long-term trend. The rainforest looks doomed eventually.
