Pesticides: UNESCO-approved?

Hvar is rightly proud of its UNESCO-recognized assets, but are they being looked after?

Hvar's UNESCO entries include the 'Following the Cross' ('Za Križen') Maundy Thursday Processions, which is on the Representative List of the Intangible Cultural Heritage of Humanity, alongside the shared listings of the tradition of making lace from the agava plant, and the Mediterranean Diet,  plus the Stari Grad Plain (Latin Ager, Greek Hora), which is on the World Heritage List. Great efforts are being made to preserve the cultural integrity of these prized historical assets. Yet there are certain obstacles which have not yet been fully recognized, which could undermine the recognition of the Stari Grad Plain and the Mediterranean Diet.

Built for family use and storing tools.

There is ongoing debate about the rights and wrongs of the buildings which dot the Stari Grad Plain. In the main, these are modern-day shelters for people working in the fields, places where tools are stored securely. Many have been built in stone, in keeping with the surrounding landscape. There are some fine renovations of old stone cottages which dated back decades, if not a century or so. There are some simple shacks, adequate for their utilitarian purpose, but not particularly attractive. There are some eco-tourism buildings, usually beautifully made small stone structures designed for shade and shelter, where visitors can enjoy Dalmatian cuisine (part of the Mediterranean Diet, after all) in exquisite natural surroundings. There are a very few more ambitious actual houses, usually very fine stone constructions, designed as holiday retreats for the owners, occasionally as rustic rental properties for guests wanting to commune with nature. All the buildings are, of course, off-grid and dependent on wells and rainwater cisterns for their water supply.

Some authorities, especially those based in Zagreb, take the view that all the buildings on the Plain should be demolished. Local people and local authorities tend to be of the opinion that the buildings, or many of them, should be allowed to stay. Some, after all, were built at a time when approval was granted in principle by the Planning Authorities, even if it was not confirmed by document. Logically, there were buildings on the Stari Grad Plain from the time it came into agricultural use under the Greeks and later the Romans. Animals and people needed shelter against the elements, whether the hot sun, fierce winds or driving rain. There is also the problem of the amount of devastation tearing all these buildings down would cause to the environment. Small though most of them are, the sum total of debris would be sizeable.

The real worry

While the debate continues over the Stari Grad Plain buildings, little attention is being paid to a much more pressing problem: the devastation of the natural environment through the relentless use of chemical pesticides.

The UNESCO description of the Stari Grad Plain states: 'Stari Grad Plain on the Adriatic island of Hvar is a cultural landscape that has remained practically intact since it was first colonized by Ionian Greeks from Paros in the 4th century BC. The original agricultural activity of this fertile plain, mainly centring on grapes and olives, has been maintained since Greek times to the present. The site is also a natural reserve.' For the Mediterranean Diet, the description covers a broad range: 'The Mediterranean diet involves a set of skills, knowledge, rituals, symbols and traditions concerning crops, harvesting, fishing, animal husbandry, conservation, processing, cooking, and particularly the sharing and consumption of food.'

Herbicides and insecticides are used regularly by many of the Plain's agriculturalists, usually twice a year, but sometimes more. There is a tragic lack of awareness of the consequences: pesticides don't work as people believe they do, but they can cause a lot of harm in many different ways. There is a mass of overwhelming evidence of the harm linked to the widely used glyphosate herbicides, but the die-hard users resolutely ignore it. Many think that pesticide use is 'normal', even 'essential'. During each year, the effects of the herbicides are often all too evident. They even appear in promotional material, presumably unintentionally.

Wild greens and asparagus, freshly foraged from the countryside, are traditional staples of the Hvar version of the Mediterranean Diet. Nowadays you have to be careful where you go foraging, to avoid being poisoned by chemical herbicide residues. Olives and olive oil are also essentials in the Mediterranean Diet. But they lose their health benefits when contaminated by chemical herbicides and insecticides.

In the video below, land contaminated with herbicide is visible at intervals, especially on a path between vineyards, shown at 2 minutes 42 seconds. Such devastation of the soil and the natural environment is an ecological disaster. Contrary to commonly held belief, the herbicide spreads through the air when it's sprayed, through the soil, and through underground water, of which there is a lot on Hvar. It lasts in the soil too. And it penetrates all the plants it is in contact with. That's why glyphosate, currently the most widely used herbicide ingredient on this planet, is found in the animal and human food chains.

The World Heritage List Criteria

Pesticide use was recognised as a threat in Croatia's Nomination to include ther Stari Grad Plain in the World Heritage List:

Yet no official action has been taken to persuade land-owners to switch to organic methods of farming. This could lead to the Stari Grad Plain being transferred to the Endangered List:

The criteria for designating natural landscapes as endamgered are set out clearly, and include pesticide use:

Opportunity for change

If the Plain was added to the Endangered List, it would not be a major disaster. On the contrary, it would present an opportunity to make the situation better. UNESCO is committed to providing help to endangered properties. In this case, it would probably consist of education in the reasons why pesticides should be outlawed from the Stari Grad Plain. But such outside intervention really should not be necessary.

Chemical pesticides have no part in Hvar's historical traditional assets. The widespread use of chemical pesticides in the Stari Grad Plain, (as all over Hvar Island), undermines the basis for including it in the UNESCO listing. This holds true for Hvar's inclusion with the Mediterranean Diet. The real heritage of the island lies in organic agriculture. That is what people expect when they come to a place which has been put on the international map as a prized heritage. The few organic farmers on the Stari Grad Plain are showing the way: it can be done! Chemical pesticide users need to wise up and follow suit. The various authorities responsible for Hvar's environment and heritage should be encouraging organic agriculture in every possible way. Only then will Hvar's Stari Grad Plain and Mediterranean Diet once again truly deserve their places on the UNESCO lists.

  • Researchers find capacity stunted by pollution was restored after introduction of ultra-low emission zone

    Children’s lungs grew bigger and stronger after the most polluting vehicles were restricted from entering London, a study has found.

    Examinations of London schoolchildren before and after the introduction of the city’s ultra-low emission zone (Ulez) found a restoration of lung capacity that had been stunted by exposure to pollution.

  • Critics said I was attacking motorists. It’s more important for me that the city’s children are no longer breathing dangerous levels of pollution

    When I introduced London’s clean air zone – the ultra-low emission zone (Ulez) – more than seven years ago, no city had ever attempted anything quite like it. At the time, the scheme in central London provoked fierce opposition. When I decided to expand it – first in 2021, to inner London, and then again in 2023 to the whole city, making it the biggest clean-air zone in the world – my detractors were louder still. I had, they claimed, declared war on drivers in blind pursuit of a policy that may not even work. All the mainstream political parties, including my own, were opposed. In recent years, though, those critics have gone quiet.

    There is now a mountain of evidence to show that the Ulez has slashed air pollution and improved air quality across London, and research published by Imperial College London earlier this year showed that this is already saving lives. Between 2019 (when I first introduced the Ulez) and 2024, estimated deaths associated with air pollution in the capital fell by around 40%. But a new, independent study published by Queen Mary University of London today goes further still, showing how – by helping to clean up the capital’s air – the Ulez is improving the lungs and lives of London’s children.

  • Food Foundation sounds alarm over supply risks and price shocks as about 40% of Britain’s food is imported

    The UK is vulnerable to food price shocks because of its dependence on imports of fruit and vegetable from countries even more exposed to the climate crisis, researchers say.

    Much of Britain has sweltered under a record five heatwaves this year and endured drought and wildfires, with the hot, dry conditions damaging crops and reducing yields of domestic produce.

  • Hottest periods this year in most sea regions would have been ‘virtually impossible’ in a preindustrial climate

    Carbon pollution has fuelled a “massive expansion” of marine heatwaves in Europe this summer, research has found, with some waters recording temperatures 6C higher than normal.

    The hottest fortnights of this year would have been “virtually impossible” in a preindustrial climate in three of the four sea regions studied, according to analysis by World Weather Attribution, while in the Celtic region, which covers much of the water around the British Isles, heat hit levels that used to strike just once a century.

  • Nooks and crannies in urban areas provide a welcome alternative to intensive farming and other rural pressures

    Wildflowers are having a rough time in the countryside, mostly from the onslaught of intensive farming with fertilisers, pesticides and herbicides and less grazing. On top of that, there are building developments, competition from invasive plant species and the climate crisis to contend with.

    The UK has lost 97% of its wildflower meadows over the last century and over half of the country’s native flowers have been in decline for 70 years.

    People aged 60 and over face dangers to their health from exposure to heat at much lower temperatures than previously thought, research has found.

    Older adults will bear the brunt of increasingly frequent sustained spells of extreme heat globally as the world continues to warm up, according to a study in The Lancet Public Health.

  • Madley, Herefordshire: The cool of our churches has been welcome to many, but my polyester robes are not made for the heat

    Every summer, while roasting in my robes, I say to myself: “I must get a lighter set.” If I had a cotton cassock instead of a polyester cassock and alb, swaying to the singing of hymns might not raise my core temperature as much. In that regard, this year hasn’t been without its challenges.

    Even so, our churches have become “cool spaces”. In Madley towards the end of term I received a call from Mr Batstone, headteacher of the primary school, wondering if classes could be held in church. Madley parish church is huge, with room in the nave for each class and a cool, subterranean crypt. I headed over later that week to find the church buzzing with children.

  • Scientists surprised to find all but two of 12 grizzlies were dead within a year of ‘feelgood’ release, unable to sustain their high-calorie diet and inclined to approach humans

    The orphaned grizzly bear cubs were bulked up with a generous diet of roadkill, watermelon, dog food and snacks donated by the public. Their contact with carers was limited to two people. Then, after up to a year in rehabilitation, they returned home to the wilds of British Columbia.

    “It’s a feelgood thing – people feel good when the cage opens,” says Dr Lana M Ciarniello, a bear specialist who tracked the Canadian yearlings in a recent study. There is a perception that bears will thrive in their natural habitat, she says. “The reality is they’re not followed up on.”

  • Officials have had to remove thousands of tons of sargassum from Florida’s beaches amid the climate crisis

    Dealing with seaweed is the bulk of Chris Bumpus’s job during the summer. As chief of conservation for Miami-Dade county’s parks, recreation and open spaces department, Bumpus is in charge of cleaning sargassum off 17 miles (27km) of county beaches. But some days, the odds are stacked against him and his team.

    More and more sargassum, a kind of floating brown algae, has been washing up on the beaches of south Florida, west Africa, the Gulf of Mexico and the Caribbean.

  • Nearly a decade after fighting ended in northern Iraq, the climate crisis has brought extreme heat and a water shortage, making life almost impossible

    The first thing that strikes visitors arriving in Faka, a small village in Sinjar district, northern Iraq, is the silence. No children play in the streets. No shops are open. Roofless houses stretch across the hillside, their walls pockmarked by shellfire, while weeds and wild grasses grow through collapsed living rooms.

    A decade after Islamic State (IS) swept across the region, war remains visible everywhere. But according to the people who returned, another enemy has quietly taken its place.

    Rajab Mohammed says the problem in his village of Faka is no longer Islamic State but water and jobs
