Mosquitoes and more

Published in Forum items

An Irish family complain to Eco Hvar about the prevalence of mosquitoes during their holiday in Vitarnja.

The family's apartment is in Vitarnja, on the coastal road between Jelsa and Vrboska, which was sprayed with a cocktail of four potent insecticides on the night of July 12th -13th, and again during the night of August 9th. The family's holiday during early August was marked by 'ferocious' mosquito bites, as pictured on their young son's leg. They are not the first to associate the obvious increase in mosquito activity with the programme of blanket anti-insect spraying ('fogging').

"Dear Eco-Hvar, We had a lovely holiday in Jelsa this year, we have been coming to Jelsa since 2004. This year we were struck by the increase in mosquitoes particularly at night. We were frequently woken up in the middle of the night with buzzing in our ears and in the mornings we would be badly bitten. I attach some photos of the bites! We are wondering if the increase in mosquito activity and their aggression could be linked to pesticide usage?" E-mail 19th August 2017.

  • Deep divisions remain after high-stakes talks end with agreement to help developing world shift to low-carbon economy

    Rich and poor countries concluded a trillion-dollar deal on the climate crisis in the early hours of Sunday morning, after marathon talks and days of bitter recriminations ended in what campaigners said was a “betrayal”.

    Under the target the developing world should receive at least $1.3tn (£1tn) a year in funds to help them shift to a low-carbon economy and cope with the impacts of extreme weather, by 2035.

  • Countries must curb production now and tackle plastic’s full life cycle, says Norwegian minister Anne Beathe Tvinnereim ahead of key UN talks this week

    The world will be “unable to cope” with the sheer volume of plastic waste a decade from now unless countries agree to curbs on production, the co-chair of a coalition of key countries has warned ahead of crunch talks on curbing global plastic pollution.

    Speaking before the final, critical round of UN talks on the first global treaty to end plastic waste, in Busan, South Korea, this week, Norway’s minister for international development, Anne Beathe Tvinnereim, acknowledged the split that had developed between plastic-producing countries and others. She represents more than 60 “high ambition” nations, led by Rwanda and Norway, who want plastic pollution tackled over its full life cycle. Crucially, this means clamping down heavily on production.

  • The Essex waterways: There’s lots of nature near my Pop’s canal boat, and there’s some inside it as well

    I wander through a secret passageway to the canal, past ivy-wound fence panels and pebbles crunching under my feet. The pathway used to be overgrown but it’s clearer now that chilly autumn has arrived.

    As I walk along the path, I notice the ruby red leaves, grasp some of the last blackberries and enjoy the bitterness on my tongue. Further along I see the familiar horse chestnut trees that always reveal the signs of the seasons. There are hedgehog-like conker shells scattered under their majestic branches. I know some have been collected by my Pop – there is a myth that conkers keep spiders away, so he has bowlfuls of them on his canal boat. I don’t believe this is true though as his boat is still full of sneaky spiders that give me shivers up my spine.

  • Advocates and officials argue that consequences of Israeli siege are inextricably linked to tackling the climate crisis

    As countries negotiate over climate finance, Palestinian officials and advocates have come to Cop29 in Baku to highlight global heating’s intersection with another crisis: Israel’s siege on Gaza.

    “The Cop [meetings] are very keen to protect the environment, but for whom?” said Ahmed Abu Thaher, director of projects and international relations at Palestine’s Environment Quality Authority, who had travelled to Cop29 from Ramallah. “If you are killing the people there, for whom are you keen to protect the environment and to minimise the effects of climate change?”

  • Traders at a big machinery show say inheritance tax changes affecting the rural economy have had an immediate impact on business

    A shiny new tractor is pulling a huge orange trailer, while a commentator explains how best to manoeuvre it to tip grain, watched by a group of farmers wrapped up warmly in wellies, coats and bobble hats, some holding spaniels on leads.

    Others are checking out the latest models of combine harvesters and crop sprayers, parked on snowy ground at the Midlands Machinery Show, but few seem to be buying, and the changes to inheritance tax for agricultural properties announced in Rachel Reeves’s October budget are never far from anyone’s lips.

  • The world will continue to be absurd, but you, with all your passion, can still make your corner of it more bearable

    The questionI am finding it ever more difficult to be in this nasty world. Everything that I cherish is being destroyed and there is nowhere to go to find solace. I’ve always loved nature – but when I go for a walk now, I see every ash tree dying, I hear the loss of birdsong, I see how few insects there are. When I read the news, I just cannot comprehend how cruel humans are able to be, racism, misogyny, religious hate, cruelty to animals… The list is endless.

    I work in climate change and am having to pretend every day that there is still a chance we can prevent catastrophic climate change. I find it ever harder to be around people who don’t get just how bad things are. I don’t have kids and am single. I can’t talk to my family about it because they are rightwing, wealthy climate sceptics. They patronise me (despite the fact I’m nearly 60 and a chief executive).

  • America’s majestic national bird was close to extinction when Tina Morris, a young researcher, was asked to help bring three chicks to adulthood. First, she had to conquer a fear of heights

    It was a daunting task, with little likelihood of success. An adventurous but anxious graduate researcher without any experience of looking after birds was dispatched to the wilds of upstate New York to become a human eagle mother: feeding, teaching – and keeping alive – three helpless eagle chicks.

    Tina Morris was to camp alone beside their artificial nest, find them food, track them when they began to fly, keep them away from danger and rescue them if they got into trouble. If they survived to adulthood, northeast America would begin to be repopulated with its national bird, the bald eagle, a majestic, much-loved raptor that had been driven to the brink of extinction by the 1960s.

  • Spain is increasingly either parched or flooded – and one group is profiting from these extremes: the water-grabbing multinational companies forcing angry citizens to pay for it in bottles

    After catastrophic floodsengulfed Valencia last month, killing more than 200 people, it might seem counterintuitive to think about water shortages. But as the torrents of filthy water swept through towns and villages, people were left without electricity, food supplies – and drinking water. “It was brutal: cars, chunks of machinery, big stones, even dead bodies were swept along in the water. It gushed into the ground floor of buildings, into little shops, bakeries, hairdressers, the English school, bars: all were destroyed. This was climate change for real, climate change in capital letters,” says Josep de la Rubia of Valencia’s Ecologists in Action, describing the scene in the satellite towns south of the Valencian capital.

    In the aftermath, hundreds of thousands of people were reliant on emergency tankers of water or donations of bottled water from citizen volunteers. Within a fortnight, the authorities had reconnected the tap water of 90% of the 850,000 people in affected areas, but all were advised to boil it before drinking it or to use bottled water. Across the region, 100 sewage treatment plants were damaged; in some areas, human waste seeped into flood waters, dead animals were swept into rivers and sodden rubbish and debris piled up. Valencia is on the brink of a sanitation crisis.

  • A Conservation International scientist shares what can be done to prevent an ‘outright alarming’ future for whale sharks.

  • A new Conservation International study measures the cooling effects of forests against extreme heat — with eye-opening results.

  • EDITOR’S NOTE:Few places on Earth are as evocative — or as imperiled — as the vast grasslands of sub-Saharan Africa. In a new Conservation News series, “Saving the Savanna,” we look at how communities are working to protect these places — and the wildlife within.

    MARA NORTH CONSERVANCY, Kenya — Under a fading sun, Kenya’s Maasai Mara came alive.

    A land cruiser passed through a wide-open savanna, where a pride of lions stirred from a day-long slumber. Steps away, elephants treaded single-file through tall grass, while giraffes peered from a thicket of acacia trees. But just over a ridge was a sight most safari-goers might not expect — dozens of herders guiding cattle into an enclosure for the night. The herders were swathed in vibrant red blankets carrying long wooden staffs, their beaded jewelry jingling softly.

    Maasai Mara is the northern reach of a massive, connected ecosystem beginning in neighboring Tanzania’s world-famous Serengeti. Unlike most parks, typically managed by local or national governments, these lands are protected under a wildlife conservancy — a unique type of protected area managed directly by the Indigenous People who own the land.

    Conservancies allow the people that live near national parks or reserves to combine their properties into large, protected areas for wildlife. These landowners can then earn income by leasing that land for safaris, lodges and other tourism activities. Communities in Maasai Mara have created 24 conservancies, protecting a total of 180,000 hectares (450,000 acres) — effectively doubling the total area of habitat for wildlife in the region, beyond the boundaries of nearby Maasai Mara National Reserve.

    “It's significant income for families that have few other economic opportunities — around US$ 350 a month on average for a family. In Kenya, that's the equivalent of a graduate salary coming out of university,” said Elijah Toirai, Conservation International’s community engagement lead in Africa.

    But elsewhere in Africa, the conservancy model has remained far out of reach.

    “Conservancies have the potential to lift pastoral communities out of poverty in many African landscapes. But starting a conservancy requires significant funding — money they simply don't have,” said Bjorn Stauch, senior vice president of Conservation International’s nature finance division.

    Upfront costs can include mapping out land boundaries, removing fences that prevent the movement of wildlife, eradicating invasive species that crowd out native grasses, creating firebreaks to prevent runaway wildfires, as well building infrastructure like roads and drainage ditches that are essential for successful safaris. Once established, conservancies need to develop management plans that guide their specified land use for the future.

    Conservation International wanted to find a way for local communities to start conservancies and strengthen existing ones. Over the next three years, the organization aims to invest millions of dollars in new and emerging conservancies across Southern and East Africa. The funds will be provided as loans, which the conservancies will repay through tourism leases. This financing will jumpstart new conservancies and reinforce those already in place. The approach builds on an initial model that has proven highly effective and popular with local communities.

    “We’re always looking for creative new ways to pay for conservation efforts that last,” Stauch said. “This is really a durable financing mechanism that puts money directly in the pockets of those who live closest to nature — giving them a leg up. And it’s been proven to work in the direst circumstances imaginable.”

    Elijah Toirai explains current conservancy boundaries and potential areas for expansion.

    Creativity from crisis

    In 2020, the entire conservancy model almost collapsed overnight.

    “No one thought that the world could stop in 24 hours,” said Kelvin Alie, senior vice president and acting Africa lead for Conservation International. “But then came the pandemic, and suddenly Kenya is shutting its doors on March 23, 2020. And in the Mara, this steady and very well-rounded model based on safari tourism came to a screeching halt.”

    Tourism operators, who generate the income to pay landowners' leases, found themselves without revenue. Communities faced a difficult choice: replace the lost income by fencing off their lands for grazing, converting it to agriculture, or selling to developers — each of which would have had drastic consequences for the Maasai Mara’s people and wildlife.

    “But then the nature finance team at Conservation International — these crazy guys — came up with a wild idea,” Alie said. “In just six months they put this entirely new funding model together: loaning money at an affordable rate to the conservancies so that they can continue to pay staff and wildlife rangers.”

    Conservation International and the Maasai Mara Wildlife Conservancies Association launched the African Conservancies Fund — a rescue package to offset lost revenues for approximately 3,000 people in the area who rely on tourism income. Between December 2020 and December 2022, the fund provided more than US$ 2 million in affordable loans to four conservancies managing 70,000 hectares (170,000 acres).

    The loans enabled families in the Maasai Mara to continue receiving income from their lands to pay for health care, home repairs, school fees and more. And because tourism revenues — not government funding — support wildlife protection in conservancies, this replacement funding ensured wildlife patrols continued normally, with rangers working full time.

    Born out of this emergency, we discovered a new way to do conservation.

    Elijah Toirai

    “The catastrophe of COVID-19 was total for us,” said Benard Leperes, a landowner with Mara North Conservancy and a conservation expert at Maasai Mara Wildlife Conservancies Association. “Without Conservation International and the fund, this landscape would have not been secured; the conservancies would have disintegrated as people were forced to sell their land to convert it to agriculture.”

    But it was communities themselves that proved the model might be replicable after the pandemic ended.

    “The conservancies had until 2023 before the first payment was due,” Toirai said. “But as soon as tourism resumed in mid-2021, the communities started paying back the loans. Today, the loans are being repaid way ahead of schedule.”

    “Born out of this emergency, we discovered a new way to do conservation.”

    A new era for conservation

    The high plateaus overlooking the Maasai Mara are home to the very last giant pangolins in Kenya.

    These mammals, armored with distinctive interlocking scales, are highly endangered because of illegal wildlife trade. In Kenya, threats from poaching, deforestation and electric fences meant to deter elephants from crops have caused the species to nearly disappear. Today, scientists believe there could be as few as 30 giant pangolins left in Kenya.

    Conservancies could be crucial to bringing them back. Conservation International has identified opportunities to provide transformative funding for conservancies in this area — a sprawling grassland northwest of Maasai Mara that is the very last pangolin stronghold in the country. The fund will help communities better protect an existing 10,000-hectare (25,000-acre) conservancy and bring an additional 5,000 hectares under protection. It provides a safety net, ensuring a steady income for the communities as the work of expanding the conservancy begins. With a stable income, communities can start work to restore the savanna and remove electric fences that have killed pangolins. And as wildlife move back into the ecosystem, the grasslands will begin to recover.

    In addition to expanding conservancies around Maasai Mara, Conservation International has identified other critical ecosystems where community conservancies can help lift people out poverty, while providing new habitats for wildlife. Conservation International has ambitious plans to restore a critical and highly degraded savanna between Amboseli and Tsavo National Parks in southern Kenya, as well as a swath of savanna outside Kruger National Park in South Africa.

    Many of the new and emerging community conservancies have been carefully chosen as key wildlife corridors that would be threatened by overgrazing livestock.

    When the first Maasai Mara conservancies were established in 2009, cattle grazing was prohibited within their boundaries. When poorly managed, cattle can wear grasses down to their roots, triggering topsoil erosion and the loss of nutrients, microbes and biodiversity vital for soil health. It was also believed that tourists would be put off by the sight of livestock mingling with wildlife.

    Cattle are closely monitored in the Maasai Mara to prevent overgrazing.

    However, over the years, landowners objected, lamenting the loss of cultural ties to cattle and herding. “That was when we changed tactics,” said Raphael Kereto, the grazing manager for Mara North Conservancy.

    Beginning in 2018, Mara North and other conservancies in the region started adopting livestock grazing practices to restore the savanna. Landowners agreed to periodically move livestock between different pastures, allowing grazed lands to recover and regrow,  mimicking the traditional methods pastoralists have used on these lands for hundreds, if not thousands, of years.

    “Initially, there was a worry that maybe herbivores and other wildlife will run away from cattle,” said Kereto. “But we have seen the exact opposite — the wildlife all follow where cattle are grazing. This is because we have a lot of grass, and all the animals follow where there is a lot of grass. We even saw a cheetah with a cub that spent all her time rotating with wildlife.”

    “It's amazing — when we move cattle, the cheetah comes with it.”

    The loans issued by the fund — now called the African Conservancies Facility — will enhance rotational grazing systems, which are practiced differently in each conservancy, by incorporating best practices and lessons from the organization’s Herding for Health program in southern Africa.

    For landowners like Dickson Kaelo, who was among the pioneers to propose the conservancy model in Kenya, the return of cattle to the ecosystem has restored a natural order.

    “I always wanted to understand how it was that there was so much more wildlife in the conservancies than in Maasai Mara National Reserve,” said Kaelo, who heads the Kenya Wildlife Conservancy Association, based in Nairobi.

    “I went to the communities and asked them this question. They told me savannas were created by elephants, fire and Maasai and cattle, and excluding any one of those is not good for the health of the system. So, I believe in the conservancies — I know that every single month, people go to the bank and they have some money, they haven't lost their culture because they still are cattle keepers, and the land is much healthier, with more grass, more wildlife, and the trees have not been cut.

    “For me, it’s something really beautiful.”
