Understanding metacommunity dynamics through plant-pollinator interactions in agroecosystems to improve the efficiency of agri-environmental schemes

Project description

Restoring the web of life in farmland

Across Europe’s farmlands, a quiet crisis unfolds. It is not just the loss of species, but the unravelling of vital relationships between plants and their pollinators. These interactions are essential for crop health and pest control, yet current conservation efforts often miss the mark. Supported by the Marie Skłodowska-Curie Actions programme, the METAGROLAND project will explore how agri-environmental schemes (AES) can better support pollinator communities across landscapes. Using spatial meta-network analysis, researchers will identify key hubs where plant-pollinator interactions thrive. Beyond ecology, METAGROLAND also investigates how farmers’ social connections influence these dynamics. By weaving together ecological data and social insights, the project seeks to redesign AES for more resilient ecosystems, and for more sustainable food production.

Objective

Maintaining biodiversity in agricultural landscapes has become a pressing societal challenge. Species interactions contribute to critical agroecosystem functions such as pollination and pest control. However, scientific evidence suggests that the rate of loss of species interactions is even higher than the rate of species extinction. Agricultural policies promote agri-environmental schemes (AES) to halt biodiversity loss on farmland, but with varying degrees of success. For example, little is known about whether AES support the growth of wildlife populations, or whether they simply concentrate local populations while depleting surrounding areas. METAGROLAND project presents an innovative research agenda that pursues effective AES design at large scales by presenting a novel interdisciplinary framework: the study of plant-pollinator metacommunity dynamics in agricultural landscapes from a social-ecological perspective. This project will firstly investigate the ability of AES and other landscape elements to attract and maintain pollinator species across landscapes, thereby gaining a mechanistic understanding of sink-source dynamics in the metacommunity. Secondly, the metacommunity structure will be investigated by applying and improving a novel methodology: spatial meta-networks. This will allow the detection of landscape characteristics that promote metacommunity cohesion and stability by identifying those landscapes that act as spatial hubs for plant-pollinator interactions across space. Third, the impact of land managers' social networks on metacommunity dynamics will be assessed to provide guidelines for effective AES design based on the synthesis of ecological processes and social dynamics. Beyond new fundamental social-ecological knowledge of agricultural systems, the results of METAGROLAND will contribute to the advancement of biodiversity conservation and agroecological practices, ultimately promoting fair, healthy and environmentally sound food systems.
