THE UNIVERSITY of Reading has warned that bee populations are set to face even more threats over the next decade, according to a new study.
A report from Bee:wild has identified the top 12 emerging threats which could accelerate the loss of vital pollinators, as outlined by ten of the world’s leading experts.
It comes as one of the first publications of Bee:wild, a new science-led global campaign to save pollinators; pollinators like bees, butterflies, some birds and bats are vital to nature and our food supply with almost 90% of flowering plants and over three-quarters of the world’s staple crops depending on them.
However habitat loss, pesticides, climate change and invasive species have caused their severe decline, including the extinction of some bee species.
Experts have explained that a new wave of threats could emerge over the next few years.
These include war and conflict, which force countries to grown fewer crop types and leave pollinators without diverse food, as well as air pollution, which directly affects their survival, reproduction, and growth.
Pesticides are also weakening them, especially as they face increasingly dangerous mixes of different pesticides, especially in developing countries.
Meanwhile more frequent and larger wildfires, destroying habitats and making recovery harder, and microplastic particles are contaminating beehives across Europe, with testing from 315 honey bee colonies revealing synthetic materials like PET plastic in most hives.
Artificial light at night is also reducing flower visits by nocturnal pollinators by 62% and inhibiting the crucial role moths and night insects play in pollination.
The report also outlines some threats that unintentionally stem from climate actions, which could be improved to protect biodiversity at the same time.
It explains that planting a mix of flowering trees as well as non-flowering fast-growing trees for carbon capture would restore pollination opportunities.
Avoiding pollinator-rich areas and restoring habitats after mining for car battery materials would also help reduce the impact of mining in the long-term.
Among the steps that the report calls on us to take are stronger laws limiting antibiotic pollution that harms bee health, as well as breeding crops with enhanced pollen and nectar for better pollinator nutrition
It also explains that transitioning to electric vehicles to reduce air pollution affecting pollinators and creating flower-rich habitats within solar parks.
It also calls for the development of RNAi-based (Ribonucleic acid) treatments that target pests without harming beneficial insects.
The University of Reading’s Professor Simon Potts, lead author and chair of Bee:wild’s Scientific Advisory Board, says: “Identifying new threats and finding ways to protect pollinators early is key to preventing further major declines.”
“By acting early, we can reduce harm and help pollinators continue their important work in nature and food production; various conservation opportunities already exist and more are emerging.
“This is not just a conservation issue, pollinators are central to our food systems, climate resilience, and economic security–protecting pollinators means protecting ourselves.”
Dr Deepa Senapathi, Head of Department of Sustainable Land Management at the University of Reading, is co-author of the report and Vice-Chair of Bee:wild Scientific Advisory Board.
She explained: “Meaningful action to protect bees is not a ;nice-to-have’ future aspiration – practical solutions that we can implement now already exist and more are emerging.
“The most promising opportunities are ones that tackle multiple problems at once; focused and determined action could significantly slow and even reverse pollinator decline while creating environments that benefit both nature and people.”
“It will take effort from everyone to address these threats–we need to maintain, manage and improve our natural habitats to create safe spaces for pollinators.
“Individual actions like providing food and nesting areas in our own back gardens can help in a big way, but policy changes and individual actions must work together so everything from gardens and farms to public spaces and wider landscapes can all become pollinator-friendly habitats.”
Eva Kruse, Executive Director of Bee:wild, which commissioned the report said: “We were already sounding the alarm on the decline of our pollinators, but this new report underlines that the range of threats are expanding.
“Rather than being filled with hopelessness, the purpose of the Bee:wild campaign is to fuel awareness, urgency and give everyone agency.
“There’s a lot we can all do to help save our pollinators, in our homes and everyday lives–planting flowering plants to feed them, providing outdoor shelter and considering healthier diets like plant-based as well as pesticide-free, all matter a lot.”
“It’s getting harder for our pollinators but we can all play a part in protecting them and building a sustainable future for all living things.”
Razan Khalifa Al Mubarak, President of the International Union for Conservation of Nature (IUCN) and Board Member of nature conservation organisation Re:wild – which is behind the Bee:wild campaign – provided the report’s foreword.
“The choices we make today will shape the future – not only for pollinators, but for all life on Earth. Together, we can ensure that these remarkable species continue their vital work, sustaining the natural world that sustains us all.”
