Understanding and tackling the decline of insects

Expected Outcome: Project results are expected to contribute to all of the following expected outcomes:researchers better understand the status and population trends of insect species and the drivers of their decline;competent authorities in charge of biodiversity policies at all levels are capable of taking informed decisions, based on better understanding and valuation of socioeconomic benefits and ecological importance of insects, including for climate action;society and relevant land managers are better informed and equipped to tackle the drivers of the decline of insects. Scope:Insects play a vital role contributing to ecosystem functions in addition to pollination, such as decomposition and nutrient cycles, soil formation (including carbon sequestration) and pest control, control functions essential for maintaining ecosystem complexity, and are an indispensable part of the food chain. Those functions are key for climate change mitigation and allow the provision of ecosystem services which have economic benefits and support human well-being. Additionally, insects play a key role in other socioeconomic areas such as medical and pharmaceutical applications (e.g. antimicrobial peptides), forensic science or biotechnology.The dramatic decline of insects, estimated around 75% in the last three decades, is raising increasing concern among scientists and in the public, since it could have far-reaching implications. In order to be able to tackle this decline, there is a need to improve our understanding of the drivers of loss and how they interplay. A better knowledge of insects themselves is necessary.With targets 4 and 5 of the EU biodiversity strategy for 2030, the EU took, among others, the commitment that by 2030 habitats and species show no deterioration in conservation trend and status, at least 30% reach favourable conservation status or at least show a positive trend, and that the decline of pollinators is reversed.
