How is climate change affecting Gloucestershire?
Here we take a look at examples of how farms, rivers and vineyards are faring in Gloucestershire.
Crop failure
An incredibly wet period in autumn meant all the wheat crops that were sown at Blackhouse Farm in Newent were wiped out.James Lowe, whose family have owned the farm since the 1950s, had to start again, opting instead to grow maize for animal feed.The process cost him £30,000. "We came to the spring with practically no crops established," Mr Lowe said.
"It is becoming more tricky, all farmers feel they are slaves to mother nature – and you've got to work with mother nature, not fight her, because she will win every time," Mr Lowe said.The farm has a water gauge that shows it has had only two spells of rain since the start of April, both about 0.4in to 0.6in (10mm to 15mm)."We have to tailor our cropping depending on what situation arises, for example, we've ended up planting maize because it was the last option we had," he said.
Low rivers
Those monitoring the River Churn, a tributary of the Thames, have measured 10 million litres of water flowing every day.For this time of year, the flow rate should be double that number, experts say."We've effectively had the driest spring on record for the Churn catchment and large parts of the Cotswolds," said hydrogeologist Dr Mike Jones.The river is lower than it was in 2022, which was the last time the area experienced a significant dry spell and heatwave, Dr Jones said.He added: "Ultimately later on in the year we ended up in a declared drought with temporary use bans. "I don't want to give an alarmist view but that's the sort of situation we are in today on the Churn."
Dr Jones is also a member of the group Friends of the Gumstool Brook, an offshoot of the Churn.The group has been trying to improve river flow into the stream, but given that the Churn in Cirencester has been recorded to have its "lowest and slowest flow this early in the year", it has been a difficult task.Met Office statistics show that from April to June 2022, 4.8in (123mm) of rain fell in Gloucestershire – and only 3.1in (79mm) fell in the same period this year.
Boost for vineyards
Vineyards in Gloucestershire have had a particularly good year, with the dry weather and long sunny days helping bring the grapes on early.It follows one of the poorest years last year with lots of rain – which was "disastrous" for the crop, said Martin Fowke, of Three Choirs Vineyard."We are flowering at the moment which is two weeks earlier than we would expect to be and that gives us a longer growing season and the opportunity for more ripeness," he said.
Mr Fowke said he believed this year was drier than 2018, which was the most recent comparable year.According to trade body WineGB, there are now 4,209 hectares of vineyards in the UK, with English wine said to contribute several billion pounds in economic activity annually.
Proposed solutions
So how do we change our environment in order to cope with the new weather patterns brought about by climate change?Professor Chris Short, from the University of Gloucestershire, regularly speaks to farmers about the measures they can put in place to cope with higher temperatures in the summer and heavier rainfall in the winter.He said: "The key thing they [farmers] are recognising is the one thing they can manage is their soil."They need their soil to be as healthy as possible so it can retain moisture for longer."
Professor Short has been looking at increasing soil health by diversifying crops, meaning a number of different crops are planted in the same field. This not only makes soil healthier but gives farmers options should a crop fail.There has also been research looking at shading crops under trees.Planting more trees is an approach that has been suggested for urban areas too, although Professor Short said much more may need to be done besides."We have so much hard surface in our cities, if you have those very localised, very heavy rainfall events, whatever system you have in place isn't going to sustain that," he said.The professor proposes use of green walls, green roofs and permeable surfaces to slow rain water down and reduce flash flooding."Several people have commented maybe this is the new norm: we can predict it's going to become unpredictable," he said.

Rain raises Rhine river levels in Germany, but ships still only part loaded
HAMBURG, July 23 (Reuters) - Rain has raised water levels on the river Rhine in Germany, but most of the river is still too shallow for cargo vessels to sail fully loaded, commodity traders said on Wednesday. Dry weather and a heatwave in June and July meant the river became too shallow for vessels to sail at full capacity. Ship operators imposed surcharges on freight rates to compensate for vessels sailing partly empty, increasing costs for cargo owners. Rain this week has caused a strong rise in water levels, traders said. The impact of the heatwave had been larger than expected, as fields which drain into smaller streams and rivers feeding into the Rhine were especially dry. Shallow water continues to hinder shipping on much of the river in Germany including Duisburg, Cologne and the chokepoint of Kaub, but vessels are able to take on larger loads, traders said. Vessels can now sail around 70% full at Kaub, and around 60% full in Duisburg and Cologne. More rain forecast in river catchment areas in coming days is expected to raise the river to approaching normal levels later this week, they said. The Rhine is an important shipping route for commodities such as grains, minerals, ores, chemicals, coal and oil products, including heating oil. German companies faced supply bottlenecks and production problems in summer 2022 after a drought led to unusually low water levels on the river.

No timeframe for Thames Water hosepipe ban to end, says company
A water company has said it can't say when a hosepipe ban will come to an end because it is "generally waiting for rain".Thames Water announced a ban last week which has come into effect for customers with postcodes beginning with OX, GL, SN, RG4, RG8 and follows bans from Yorkshire Water, Southern Water and South East Water and affects almost 1.1 million people in Gloucestershire, Oxfordshire, Berkshire and Tucker, demand reduction manager at Thames Water, said he appreciates how frustrating it is when water use is restricted and there are many leaks at the same time, but said the company is "doing everything they can to deal with it". The unusual dry spell and heatwaves over the past few months triggered the ban and some residents and businesses in Berkshire have told the BBC it is "restrictive and difficult". Professional gardener Janet Wood said: "It is difficult because sometimes we only go to our customers' gardens once a week, sometime fortnightly."If they aren't watering then that makes it very difficult for us, because everything is dying by the time we visit again."It can be very depressing to see."Ms Wood explained that if gardeners are "lucky" then "our customers have invested in a drip system" - which are very small hoses that drip water gradually into the flower said: "These are very economical, effective and not part of the hosepipe ban."Otherwise, we have to hope our customers are using a watering can and are giving every plant a good dose of water, at least twice a week.""The situation is very frustrating," she added."We need to be looking at drought-proof plants that can withstand longer periods without water and finding ways to be economical with water because it is something we are going to have to deal with more in the future." Kevin Browne, vice-chairman and honorary treasurer of Henley-on-Thames Bowling Club, said the ban means the club is "restricted" even though they are a sports added that Thames Water has been "very ambiguous" with its explained that the club has a "delightful green lawn" which looks healthy because there has been "plenty of rain in the last few days"."If we have the weather we have had over the last three months then it will give us lots of problems and could be restrictive," he added."We have a number of areas in the lawn where it goes really brown, particularly where our sprinklers don't cover the lawn properly, but we can water those patches with the watering can."He said the club has been told by Thames Water that "if things really get dire then they would be sympathetic to us using our sprinklers".And Mr Browne is hopeful the club won't be badly impacted. "With the weather the way it is now we are not going to be affected in any major way whatsoever," he said. You can follow BBC Berkshire on Facebook, X (Twitter), or Instagram.

Century-old dam under strain as floods increase in US and federal funds dry up
More than 18,000 properties that sit downstream of a series of a century-old Ohio dam are at risk of flooding over the next three decades, according to climate data, as the Trump administration continues to roll back investments that would aid in keeping the waters at bay. In a part of the US that's largely flat, the view from above the Huffman dam in south-west Ohio is rare. From the bike trail atop the dam, the shimmering lights of downtown Dayton appear to the south. Cargo planes from a nearby air force base circle overhead and water from the 66-mile-long Mad River gushes underfoot. But the dam serves a far more pressing purpose: holding back up to 54bn gallons of water – enough to fill 82,000 Olympic-size swimming pools – during flooding events. Nearby, more than 21% of all properties downstream are at risk of flooding over the next three decades, according to First Street, a climate risk data modeling organization. That percentage accounts for 18,596 properties in Dayton. The five massive dry dams and 55 miles of levees west and north of Dayton were built in the aftermath of catastrophic destruction that befell the Ohio city in 1913, when 360 people died and flooding in three rivers that meet in the city center wiped out the downtown area. But today, it and many other communities around the midwest are once again at risk of flooding. 'Our system has experienced 2,170 storage events. The flood in April ranked 12th,' says MaryLynn Lodor, general manager of the Miami Conservancy District, the authority overseeing the regional flood prevention system that includes the Huffman Dam. The flooding early last April saw five to seven inches of rain inundate homes, roads and parks, and caused power outages for thousands of people across hundreds of miles. Extreme precipitation events are happening with increasing regularity at a time when, across a region that's home to the country's two major, high-discharge waterways – the Ohio and Mississippi rivers – decades-old flood prevention infrastructure is falling apart. From Indiana, where authorities in charge of a dam at a youth camp that sees 15,000 visitors annually warned of failure during last April's flooding, to Illinois and Minnesota, reports are appearing with increasing regularity of '100-year' floods threatening the integrity of, and in some cases destroying, dams. Five years ago, the Edenville Dam in central Michigan failed following days of heavy rain, prompting the evacuation of 10,000 people and the failure of another dam downstream. The dam is situated at the confluence of two rivers, and in 2018 its owner temporarily had its license taken away due to fears it couldn't pass enough water at high flood levels. Lawsuits and an expense report of $250m followed the dam failure. Data from Michigan's department of environment, Great Lakes and energy, found that of the state's recorded 2,552 dams, nearly 18% were rated as in 'fair', 'poor' or 'unsatisfactory' condition. Despite this, little change has been enacted in Michigan. 'The reason this is popping up everywhere in the country is because it's a massive ageing infrastructure problem,' says Bryan Burroughs, a member of a now-closed state taskforce that sought to investigate the status of dams across Michigan following the Edenville incident. He says the taskforce's recommendations have largely not been enacted. 'To date, the only ones that have been taken up and addressed to any level are the ones that our state department of environment, Great Lakes and energy are able to oversee themselves. Regulatory changes have not been picked up legislatively,' Burroughs continued. Through the Inflation Reduction Act, the Biden administration had made investing in America's ageing infrastructure over the course of many years a priority, with $10bn dedicated to flooding mitigation and drought relief. An additional $3bn was allocated in 2021 through the Infrastructure Investment and Jobs Act for dam safety, removal and related upgrades. Since Donald Trump entered the White House in January, the administration has vowed to roll back much of those investments. Hundreds of dam safety and other staffers working at dams in 17 western states have been laid off in recent months. Before the 4 July flood disaster in Texas, the Trump administration had pledged to close the Federal Emergency Management Agency (Fema). With more than 92,000 dams across the country, the Society of Civil Engineers estimates the cost of repairing the country's non-federal dams at $165bn. In Ohio, the Miami Conservancy District has been outspoken in highlighting that the dams it is responsible for are in need of repair – in particular, the upstream walls of two north of the city of Dayton. Levees it manages 'are subject to the costly, federally mandated Fema accreditation process, but there is no adequate funding source.' Last year, the district said it needs $140m to bring the region's dams and levees up to safe levels over the coming decades. Over the past 80 years, the organization has seen a 228% increase in the volume of water its dams store, meaning the structures today must work harder than they did in the past to hold back the water. 'As we're looking at having to make reinvestments, we are looking to try to secure some funding through the state and federal governments,' says Lodor. 'We have not gotten much support and federal dollars or state money to be able to do the system. It's already been invested in by the local communities; it would be very difficult for this to be on the backs of the locals.' Many dams hold back water that's used by fishers and recreators – an issue that's creating tension in many communities. In White Cloud, Michigan, authorities have had to draw down much of the lake water behind a 150-year-old dam due to fears for its structural integrity, angering locals. As in Texas, dozens of youth groups and Christian camps across the midwest use lakes and waterways downstream of ageing lowhead and other dams for programming and outdoor activities. Emails and messages left by the Guardian with the owners of an at-risk dam at a camp in Indiana used by thousands of children every year received no response. While compared with other parts of the US the midwest does not have a lot of dams whose main purpose is for flood control due to geological and topographical reasons, Ohio and much of the wider midwest have seen 'record-setting rain' this year. 'The weather has changed,' says Burroughs. 'What used to be a one-in-100-year flood event might have happened three times in the last 40 years.'
