Phasing out synthetic pesticides and fertilisers and aggressive emission reductions among series of solutions outlined by scientists
The world must eradicate pesticide use, prioritise nature-based farming methods and urgently reduce water, light and noise pollution to save plummeting insect populations, according to a new “roadmap to insect recovery” compiled by experts.
The call to action by more than 70 scientists from across the planet advocates immediate action on human stress factors to insects which include habitat loss and fragmentation, the climate crisis, pollution, over-harvesting and invasive species.
Phasing out synthetic pesticides and fertilisers used in industrial farming and aggressive greenhouse gas emission reductions are among a series of urgent “no-regret” solutions to reverse what conservationists have called the “unnoticed insect apocalypse”.
Alongside these measures, scientists must urgently establish which herbivores, detritivores, parasitoids, predators and pollinators are priority species for conservation, according to a new paper published in Nature Ecology & Evolution. The animals are crucial to the healthy functioning of ecosystems by recycling nutrients, serving as pollinators and acting as food for other wildlife.
The paper comes amid repeated warnings about the threat of human-driven insect extinction causing a “catastrophic collapse of nature’s ecosystems”, with more than 40% of insect species declining and a third endangered, according to the first worldwide scientific review, published in February 2019.
