Fostering landscape immunity to protect human health: A science-based rationale for shifting conservation policy paradigms

Anthropogenic land use change is a major driver of zoonotic pathogen spillover from wildlife to humans. According to the land use-induced spillover model, land use change alters environmental conditions that in turn alter the dynamics between zoonotic pathogens and their wildlife hosts. Thus, in response to the global spread of the SARS-CoV-2 virus (the agent of COVID-19 disease), there have been renewed calls for landscape conservation as a disease preventive measure, including by the G7 Ministers responsible for Climate and the Environment. Landscape immunity, as a new construct, points to four paradigm shifts the world must favor to effectively mitigate pandemic risks. We provide a landscape immunity primer for policy makers and make the case for world views that place Homo sapiens within ecological systems, regard human health as an ecological service, prioritize investments in prevention, and apply ecological restoration to human health goals. Crisis is a conversation starter for reimagining and recommitting ourselves to what is most vital and generative. We urge world leaders to make the move to a nature-positive world.

Automated summary

Anthropogenic land use change plays a significant role in the transmission of zoonotic pathogens from wildlife to humans. In response to the global spread of COVID-19, there have been calls for landscape conservation as a preventive measure. The concept of landscape immunity emphasizes the need for paradigm shifts in viewing human health as an ecological service, prioritizing prevention, and integrating ecological restoration into health goals.
