Understanding and tackling the decline of insects

Overview

The Horizon Europe call HORIZON-CL6-2026-01-BIODIV-01 is focused on "Understanding and tackling the decline of insects," with an opening date of April 17, 2026, and a submission deadline of September 17, 2026. The initiative, part of the larger research and innovation framework under Horizon Europe, emphasizes the severe decline of insect populations and aims to fund comprehensive projects that address this critical issue.

The total budget allocated for this call is €13 million, with an expectation to award two grants, each amounting to €6.5 million. Eligible applicants for this funding opportunity include research organizations such as universities, public and private research institutions, and private companies engaged in research activities, with a requirement for applicants to operate through consortia. Individual researchers may not apply directly.

The funding type falls under a budget-based action grant, categorized as a Research and Innovation Action (HORIZON-RIA). This call requires collaborative efforts from multiple applicants typically from different EU or associated countries, reflecting the complex nature of the research topics involved.

Geographic eligibility includes EU member states and associated countries, with potential participation from third countries under specific agreements. The initiative prioritizes sectors related to biodiversity conservation and ecosystem services, particularly focusing on insect ecology, conservation biology, climate change mitigation, and genomic approaches to improve understanding of insect populations.

Projects should target the research and development stages, aiming to enhance scientific knowledge regarding insect diversity, analyze drivers behind population decline, and develop practical ecological strategies. The application process involves a single-stage submission through the EU Funding & Tenders Portal.

The call highlights the importance of ensuring that the data produced is Findable, Accessible, Interoperable, and Reusable (FAIR) and emphasizes international collaboration. Specific success rates for proposals are not listed, but historical trends suggest that submission competitiveness is high, possibly ranging from a 5–15% success rate.

Co-funding is not formally required, as the EU grant could cover up to 100% of eligible costs, although additional resources from consortium partners are encouraged to enhance project proposals.

Overall, this funding initiative represents a significant effort to tackle biodiversity challenges, particularly the alarming decline of insect populations, by supporting research that can inform policy and practice aimed at sustaining ecosystem health and balancing environmental priorities.
