Conference: Protect our Health, Water & Biodiversity from Pesticides
6 October 2026 10:00 – 14:00
Europe House, Balfe Street 5, Dublin (D02 E7K4) & Online
Hosted by The Environmental Forum, Pesticide Action Network Europe, Sustainable Water Network (SWAN) and Environmental Pillar.
Under the upcoming Irish Presidency of the Council of the European Union, crucial discussions are expected on the future of EU pesticide regulation, including the proposed Food and Feed Safety Omnibus package. Civil society organisations, scientists, water sector representatives and beekeepers across Europe have expressed serious concerns that parts of the proposed deregulation agenda could weaken environmental and health protections, particularly regarding pesticides and pollinator safety.
This high-level conference aims to create a constructive platform for dialogue between policymakers, scientists, civil society and stakeholders. The event will present the latest scientific evidence on pesticides’ impacts on health, water quality, biodiversity and pollinators, while discussing how EU legislation can better uphold the precautionary principle and support a truly sustainable agricultural transition.

In the Strengthening Local Food Economies in Ireland project (2025-2026), Feasta, Cultivate and Talamh Beo have worked to better understand Ireland’s small but vital local food sector and to develop proposals to support it in the transition to a ‘wellbeing economy’ which can enable human thriving within planetary boundaries.
We are now pleased to invite you to the Feeding Ourselves’ Local Food Symposium in Trinity Business School on Thursday October 29th as we share our research findings and policy proposals developed over the past two years.

- Basic Income for Local Food Farmers Policy Proposal
In addition to sharing our project findings, we’ll be joined by inspiring thinkers and doers who are enabling stronger local food economies across Ireland and the UK.
