The sustainable farming organisation is urging politicians gathering in Montreal for the UN Biodiversity Conference to protect nature by backing the proposed target to reduce pesticide use by two thirds by 2030.

This target has been proposed in the first draft of the post-2020 biodiversity framework that world leaders are set to consider during the conference, with a view to making agreements to protect nature similar to the Paris Agreement's climate commitments.

The Soil Association is also calling for the UK and EU governments to prohibit unethical exports of highly hazardous pesticides that are banned for use in the UK.

As highlighted in the recent Stop Poison Poultry campaign, these dangerous chemicals are exported for use on soya and other crops in Latin America, where they are poisoning exotic wildlife. Soya is imported in huge volumes by the UK as feed for British chickens, with no testing carried out for pesticide residues.

Soil Association Head of Farming Gareth Morgan said: "The UN Biodiversity Summit will be a COP-out if world leaders fail to end the pesticide treadmill. The catastrophic crash in wildlife populations cannot be reversed in a world that is not committed to phasing out these toxic chemicals. The target to protect 30% of land and ocean by 2030 will not be enough – all land, including British farmland, must protect and restore nature as part of its vital role in sustainable food production.

"We know that pesticides are directly linked to declines in bees and other vital insect species, as well as harming the wildlife that eat them, even in surrounding conservation areas. We also know that bans on specific chemicals do not work as they are simply replaced by another, with farmers given little to no support to move to nature-friendly systems.

"Our new Prime Minister must show true leadership at COP15 by making a commitment to end the routine use of increasingly expensive toxic chemicals in farming. His priority should be helping farmers find better long-term alternatives, not protecting the interests of agri-chemical companies. The first step the UK government should take is to ban UK businesses producing and exporting destructive pesticides that are banned here."

The Soil Association is also urging the UK government to publish the alarmingly long-overdue National Action Plan for Pesticides – its five-year plan for reducing pesticide use which has not been updated since 2013.

This should include pesticide reduction targets and investment for farmer-led research into alternative pest control methods that work with nature rather than against it – for example by using predatory insects.

A robust Environmental Land Management Scheme that rewards farmers using these nature-based solutions is also essential.
