| description | Wild pollinators play a crucial role in maintaining healthy ecosystems and sustaining agricultural productivity. However, their survival is at risk due to habitat loss and land use changes, exacerbating the ongoing biodiversity crisis, and jeopardising global food security. We assessed the contribution of native vegetation cover to pollination and avocado crop yield by modelling the abundance of native bees and the pollination services they provide in agroecosystems of the Aconcagua River basin in Central Chile. This region stands as a critical biodiversity hotspot, currently confronted with the challenge of land use change, especially due to the expansion of avocado (Persea americana Mill.) monocultures. Our findings revealed a clear relationship between native bee abundance, pollination services, and avocado yield as a function of natural vegetation cover surrounding the crops. Areas with a higher proportion of native vegetation exhibited the most abundant supply of pollination services, while within avocado crops show lower levels of pollination support. A spatial mismatch between supply and demand for pollination revealed by our results indicates that agricultural expansion threatens native pollinators and agricultural yield production in this region. The development of pollination maps has been proposed as a strategic tool to guide land-use planning decisions within agricultural landscapes. Prioritizing the conservation of native vegetation or adopting biodiversity-friendly practices can help mitigate the effects of agricultural expansion on wild pollinators. These strategies are vital for safeguarding biodiversity, ensuring food security, and mitigating the far-reaching impacts of the current biodiversity crisis. [Figure: see text] |
