Prioritizing India's landscapes for biodiversity, ecosystem services and human well-being

Biodiversity conservation and human well-being are tightly interlinked. Yet, mismatches in the scale at which these two priority issues are planned and implemented have exacerbated biodiversity loss, erosion of ecosystem services and declining human quality of life. India houses the second largest human population on the planet, while < 5% of the country's land area is effectively protected for conservation. This warrants landscape-level conservation planning through a judicious mix of land-sharing and land-sparing approaches combined with the co-production of ecosystem services. Through a multifaceted assessment, we prioritize spatial extents of land parcels that, in the face of anthropogenic threats, can safeguard conservation landscapes across India's biogeographic zones. We found that only a fraction (similar to 15%) of the priority areas identified here are encompassed under India's extant Protected Area network, and furthermore, that several landscapes of high importance were omitted from all previous global-scale assessments. We then examined the spatial congruence of priority areas with administrative units earmarked for economic development by the Indian government and propose management zoning through state-driven and participatory approaches. Our spatially explicit insights can help meet the twin goals of biodiversity conservation and sustainable development in India and other countries across the Global South. Biodiversity conservation is critical for promoting ecosystem services and human well-being, but current conservation efforts fail to protect most high priority zones. A mix of land-sparing and land-sharing is needed to safeguard critical ecosystems in India and across the Global South.

Automated summary

Biodiversity conservation and human well-being are closely linked, but the mismatch in planning and implementing these priorities has led to biodiversity loss and declining quality of life. India, with a large population, has very little land effectively protected for conservation. Landscape-level conservation planning, combining land-sharing and land-sparing approaches, is necessary.
