UK voters face difficult choices

peter 0

Next month town halls up and down the UK will be holding local elections. In past years, this multifaceted media matrix has not been covered in these pages. But this year, when the votes are counted, the distribution of political power across the landscape will change before a single committee meets or a single bin is emptied.

On May 7, voters will choose more than 4850 local councillors to run 134 local authorities. While the buildings will not look any different, the ways in which they will work will change literally overnight. Will the root causes of regional misunderstandings melt away in the warmth of a new dawn? The newly-constituted authorities will need to ensure   funds remain available for local planning officials to have a better grasp of agricultural issues in their decision-making processes. Pigs might fly. Making waste disposal sites accessible and affordable can reduce the temptation to resort to fly tipping. Realistically, rural policing policy can only be based on lower population densities outside urban zones.

While canvassing for the local council elections, candidates can expect to face hostility on the doorstep on topics they have no control over. These could be items such as longer waiting lists for healthcare or services that voters believe to be cheaper/more reliable/generally favouring urban areas. 

The lower density of rural populations made the provision online capacity less attractive for early commercial internet providers. Satellite services get round a lot of the transmission issues that faced early broadband services, but  are not totally immune from signal issues, such as sunspots and solar flares. Sending a service engineer to repair a network outage in Dagenham can be covered by a simple phone call, while restoring an array of satellites takes some forward planning.

Tom Broadshaw has been speaking up for years to get fairer treatment for everyone in the supply chain.

Rather than accepting crumbs from the urban table, UK farmers need a market mechanism that protects their interests. For instance, as the law stands, farmers have no rights as suppliers to supermarket suppliers. This fails to recognise the role food producers in mult-party supplier agreements, as well as being unfair. This particular bone of contention  has been running for years now, NFU President Tom Bradshaw explained: “Farming is the backbone of our rural economy and lifeblood of rural communities. Our farmers manage over 70% of the landscape, protect   enhance the environment and produce food for 70 million people.”

Confidence within the sector remains low. “Farm businesses are under extreme cost pressure, Bradshaw added. “Pressures for feem has been runningd, fuel and fertiliser, are exacerbated by geopolitical tensions,” he declared. Starting with the invasion of Ukraine and now the war in the Middle East, the political outlook is not predictable. Add it to the unstable climate and extreme weather and we all face problems that   impact our ability to produce food.

“Decisions being taken by local authorities can have a direct and lasting impact on farm businesses and the communities they support. By championing pro-farming policies on areas suchttps://urbanfoodchains.uk/wp-admin/admin.php?page=wps_overview_pageh as planning, rural crime and the procurement of more British food, councils aren’t just supporting individual farming businesses — they can help turn the tide and shape the future of our industry by increasing our collective resilience.”

draft animals haulage three quick questions

From legs to wheels

Having covered a blank canvas with lengthy discussions of horses’ roles in the transport of goods (click on a “horse” badge for the full list), the moment has arrived to resolve any lingering doubts. Registrations of commercial vehicles on British roads grew steadily in the 1920s: the figures used in this table  are all civilian, there are no military registrations to factor in. 0 At the start of the first world war, the British government commissioned regular orders with about half a dozen automotive manufacturers equipped to fulfill wartime orders. During the hostilities, these firms built 20,000 vehicles for the military – mostly lorry chassis ready for adaptation once their role had been allocated. The government disposed of a further 6,000 vehicles that were either no longer required or beyond repair.

The only army horses ever to return to the UK were those belonging to officers, some 65,000 in all, out of a total of close on a million. There was very little reliable data on the UK’s horse population at this time. The country had been a long term importer of horses since the mid-nineteenth century. There were groups of draft horses traded by specialist breeders, who saw to it that strong lines of Shire horses, Suffolk Punches and Percherons were kept available for companies that needed to patch a gap in a team, or other specific need.

The British army commandeered as many horses as it could lay its hands on. The entire industrial world was short of mules and horses during the 1920s. It was the growing reliability of automotive products that helped some to turn the corner. There was a persistent chafing between England’s lorry drivers and coachmen who were still in a job. Knowing that the brakes on lorries were often barely fit for purpose, coachmen would wind up lorry drivers while loading their vehicles and persuade them to increase their load to a point where the vehicle was a danger to other traffic.

Wild bees pick and choose

peter 0

After eight years tracking the foraging preferences of eight species of wild bees, researchers in North America have identified patterns in their choice of pollens. Protein contents in pollens studied by a team drawn from Northwestern University and Chicago Botanic Garden ranged from 17% to 86%. Large species were found to prefer high protein pollens, while smaller bees in the study homed in on pollens with higher carbohydrate levels and fat contents. This range is wide enough to make co-existence possible and support seasonal variations within colonies through the summer.

Science News covered the story here, Northwestern published this, which stresses how little twenty first century scientists know about wild pollinators at a landscape level. Why we listen to pesticide manufacturers rather than wild bumblebees defies logic.

Disjointed thinking on prices.

peter 0

Responding to Linlithgow’s insistence on the need for market data to be available on a regular basis, a senior MAF official, Mr RJ Thomson, submitted a more detailed version of the government’s reservations over broadcasting raw price data without a standardised format or structure. Thomson told the commission that MAF was working on a “comparative index” that would somehow make sense of wholesale and retail price movements. It couldn’t be done in the 1920s and I’m not convinced we could do it in 2025. Take the example of a pig producer with slaughter weight bacon pig to sell in 1925. The creature is sold to a curer, who kills the animal and splits it into two sides of bacon. So far we have two mirror image halves of the same animal. One side of bacon goes to a Drury Lane emporium, the other to a Tyneside grocer on the east coast. The cuts that are taken off a London side of bacon, sold in a well-to-do part of London will earn more than the side of bacon shipped to Newcastle, even when the higher shipping costs are factored in. It is so predictable, but illogical, and index numbers won’t explain it.

It is not difficult to spot a flaw in M AF’s argument: the cumulative effect of the changes made at each stage are not counted as part of the process.  Is this the only structural flaw?

Marketing insects takes more than buzz words

It is easy to make a case for raising insects as a food crop, the farming industry done this sort of thing all the time for some pretty unsavoury byproducts. However, it is hard to persuade western consumers that it could be cool to include insects in their daily diet. In parts of the world where insects are on the menu, the trade is a local business, more local loop than long haul. Ironically, increasingly affluent countries such as China are pushing up their meat consumption and cutting back on traditional specialities.

Writing in Sustainable Production and Consumption 49, Dustin Crummett notes a lack of food industry research into plant or insect products that might challenge meat in the weekly shop. The head of the insect institute, Crummett draws on philosophy and religion for a lot of his work: but his disappointment is unmistakeable.

His frustration arises from the difficulty of making one meal ingredient replace another. His argument is simple: lower resource ingredients mean less costly food. However, the additional habitat requirements and changing user profile can add costs that were once disregarded by economists. Counting a price calculation differently does not necessarily mean something costs less, it just costs differently.

Leverage for horses

This diagram from a US army manual issued in 1916 shows the standard loading for a pack animal.

It is time to review how draft animals are connected to their loads. The simplest example would be a pack horse or a mule, in the days when mule trains carried clay to pottery workshops. The Devon clay that was transported this way earned the name of ball clay, since it was shaped into large balls and carried in a double bag carried on the animal’s back, where a saddle might otherwise have gone. Pack animals are often quite light, enabling them to cross rugged terrain, where roads were not available. It is important to keep a regularly updated note of a draft animal’s weight, taking care not to expect them to carry more than 15-20% of their current weight.

Take a half ton horse, hitch it up to loaded lighter, and you’re off!

Carts redistribute a load, but slowing down or stopping can be more demanding, particularly when going downhill. The most efficient means of transport, particularly for heavy consignments such as building supplies, is the canal barge. This can be hauled by a (large) single horse, even when loaded with several tonnes of goods.

Horses, pigs and numbers

The relentless development of machine guns and heavy artillery from the turn of the twentieth century raised the stakes of warfare in previously unimaginable ways. Just as there is a case to argue for a wider interpretation of margins, to reflect a product’s costs and value to the economy, there is also a case to be made for revising the criteria by which these items are judged to be of use. Agriculture brings together a number of inseparable variables just to survive, let alone be profitable, making complex trade-offs on the way. Take animals, for instance.

From conception to weaning successive generations of pigs, producers face a steady pull on their resources. In the case of pigs, there will be little prospect of selling from a new litter until the new arrivals can leave their mothers’ sides and feed independently. Once this milestone has been passed, options will become available for breeders.

Animals that are to be raised for slaughter will have a target slaughter weight, somewhere around 100kg for pigs. Any heavier than that and the earning potential will drop steadily, as more feed is consumed and overheads rise. This brings us to a vital distinction that is easily overlooked. The pig producer will generally earn average money by the standards of the sector if the young animals wean successfully and go on to gain a hundred grams per day for the next six months. The market is front-end loaded and is run like clockwork down to the final 24 hours.

The opposite is true for draft animals, which earn their keep by staying alive and working to whatever age their breed can manage. The lead times are longer, the resources needed are greater and in the early 20th century users like the British army were buying extensively for matched pairs and teams of six and more. It is quite clear that by sending draft animals off to battlefields, their value will be turned into an increasingly expensive remounting cycle of the military’s own making, in which the animals can perish within hours of arriving behind the lines. Even if brood mares are kept away from warfare, the early years of the twentieth century effectively wrote a series of blank cheques for the makers of commercial motors and trucks, to fill the haulage gap caused by modern warfare.

Verdun: the turning point

peter 0

When the first world war started in 1914, the world’s armies were accustomed to seeing imposing troops on horseback leading charges across open ground and engaging in the thick of the action. By the end of the battle of Verdun, in December 1916, the former cavalry units were to be found changing their sabres for machine guns and driving armoured vehicles instead of riding horses.

Verdun marked a pivotal point in the first world war, claiming so many lives that it was known as the “meat grinder”. To this day, farmers are still digging up horseshoes from the former battlefield. After decades of developing increasingly powerful artillery and with the arrival of mechanised warfare, the twentieth century battlefield witnessed the massacre of draft animals  on a scale never previously imagined. 

The British Army did not appreciate just how few horses it could afford to lose. Moving artillery pieces, carrying munitions to gun emplacements, at the turn of the century, modern armies could not operate without horses. From the front line to the billets, draft animals were ever-present. The first world war was deadly: on a particularly bad day, over 7,000 were killed in a conflict that lasted for years and claimed millions of equine lives around the world. Of these, nearly half a million were attached to the British army in some way. Faced with the eye-watering costs of procuring and transporting horses, the government set up the British army veterinary corps. Its skilled veterinary surgeons treated nearly three quarters of a million draft animals.

Despite going to war with extra horses to keep the army supplied, the German government had problems procuring fodder and some animals starved to death. Importing horse-related items was particularly difficult since traders were refusing to take German currency.

Around the world, the heavy losses of working horses created strong demand for alternative transport capacity. In Britain, the War Office pushed up demand for commercial vehicles by dumping 6,000 war surplus lorries and trucks on the market at bargain prices. It is hard to gauge the full extent of wartime losses and their impact on the wider economy, but many businesses that used to be horse-based changed to offer engineering and driving skills.

Horses were among the first animals to be domesticated during millennia of prehistory. You can be sure that the energy needed to build the monuments and cities of antiquity came from horses, mules and donkeys, if it did not come from slaves.

Horse sense

A cornerstone of Urban Food Chains crystallised this evening. Fundamental to the structure of a supply chain is the basic unit of transport and energy. Taking three major themes of this blog, let’s unpack the topic. First, before the dawn of time, generations of early agriculturists worked for millennia to domesticate species and crops that we would recognise today. They also tamed fire, an evolutionary trump card. Their lasting achievement was to breed forerunners of today’s strategic ungulates: cows, pigs, sheep and horses. Fast forward to the early twentieth century, when the first world war slaughtered millions of draft animals.

This high tech cull of horses, in particular, damaged the bedrock of the agricultural world. Livestock numbers would take decades to restore, if indeed there was either the economic resources or the political will to do so. The first world war was a reset that made way for change on a global scale, for humans and animals alike. Thousands of years spent establishing stable working relationships turned to dust in the heat of battle.

The penny dropped when I read Christopher Turnor, an author of the time, complaining that the UK had too many pastures, they were blocking food production. The origins of all this empty grassland are to be found in Edwardian England, but the wartime cull of draft animals accelerated the trend. The rest is not so much history as a race to plug the economic gaps left by the ravages of war.

Brexit's legacy Denmark Europe fish livestock

Huffin’ and puffin

Fish for lunch…

From the soaring concrete cliffs of Brussels there is an impending explosion of anger. The reason? Look at Charles Sharp’s impressive picture of a puffin, just about to enter the home burrow with a beak full of sand eels. It is the fish, not the bird,  that is fanning the flames, by the way.

For all its comical looks, the puffin is an important indicator in the monitoring of the marine environment around the British Isles. Researchers are particularly interested in the fish stocks that support this distinctive seabird. The  term sand eel is a generic label for a group of about 200 fish species that resemble eels but are not related. They burrow into sandy seabeds and hide from predators while keeping an eye out for their own lunch. Hard to catch in open water, they are easy to scoop up in a dredge, as Danish fishermen have done for centuries.

Puffins are far from being the only bird species to be tracked by scientists. It just happens to be the cutest one of the bunch. The puffins’ lunch, by the way,  is at constant risk of damage from bottom trawling, that is to say beam trawls or dredgers and other devices. Scallops is one species to be caught in dredgers, while cod is a target species for many beam trawls.

Back in January this year, the UK government announced a ban on dredging for sand eels in UK-controlled Marine Protected Areas (MPAs). For the record, bottom trawling is allowed across 98% of the MPAs concerned, suggesting that the state of the seabed has not been a political priority for years. In the North Sea, with its sandy sea floors, there are still  beam trawlers fishing demersal species and small number of Danish dredgers who, between them, hold about 90% of the 160,000 tonne sand eel fishing quota. (UK and EU total) 

The origins of the Danish sand eel fishery go back to the soaring livestock holdings of the late nineteenth century, which set the Danes looking for cheap ways of feeding animals. Initially, small dredges were fitted to inshore boats, scaling up in the early twentieth century to purpose-built diesel powered vessels with an ever greater range. For some reason, as with a number of other fisheries, nobody imagined that the fish stocks would ever decline: until, that is, the catches started to drop. With growing numbers of animals on livestock holdings, the potential earnings from sand eels rose, as did the pressure on the fish stocks. Sand eels, along with other oily fish and suitable bycatch, are the ingredients of fishmeal, an industrial end product turned out in large quantities by refineries that earned a living clearing up after the high value fish processors in fishing ports. 

In the early days of indoor livestock, fishmeal was added at two thirds to one third cereals. As researchers extended their knowledge of livestock nutrition,  the proportion of fishmeal was reduced, making animal feed more profitable or cheaper, depending on your involvement in the process. To ensure an illusion of sustainability for food production in the late twentieth century, the European Commission devised the Common Fisheries Policy, which used its budget to subsidise a rise in the European fishing industry’s tonnage and horsepower, ensuring an ever more unstable fishing industry. 

Fast forward to 2024, and the European Commission is threatening to trigger a dispute procedure under the EU-UK Trade and Co-operation Agreement (TCA). The Commission is acting on behalf of Danish sand eel fishers with fishing vessels to maintain. If agreement is not reached by mid-June, the Commission  can request a judgement on the UK’s  action. While any hearings may be carried over into September, the European Commission is calling for an “evidence-based, proportionate and non-discriminatory” approach to protecting marine environments.  

“The UK’s permanent closure of the sand eel fishery deprives EU vessels from fishing opportunities, but also impinges on basic commitments under the EU-UK Trade and Cooperation Agreement,” warned commissioner  Virginijus Sinkevičius. “Measures are already in place to protect this important species, including by setting catches below the scientific advised levels and closed areas for protecting seabirds,” he added. London responded, saying that DEFRA had not authorised any sand eel quota for British vessels for the past three years. Marine protection NGOs across Europe have launched a campaign to end bottom trawling, which is still allowed in 90% of the EU’s marine protected areas (MPAs). Last year Europe agreed to an EU Marine Action Plan that phases out bottom trawling by 2030. This has some way yet to go.

According to the European Market Observatory for Fisheries and Aquaculture Products (EUMOFA) the EU produces between 10% to 15% of the world’s fishmeal and fish oil output. Tonnages of EU fishmeal range from 370,000 tonnes and 520,000 tonnes, while fish oil ranges between 120,000 and 190,000 tonnes. Denmark accounts for nearly half the EU’s total output. In addition to sand eels, EU processors use small pelagics, such as sprats, whiting or herring, all regulated with quotas and topped up with trimmings from fish processors. EU demand for fishmeal has dropped in recent years and is currently hovering around 450,000 tonnes/year.
