The article "Unhealthy Landscapes: Policy Recommendations on Land Use Change and Infectious Disease Emergence" by Jonathan A. Patz et al. discusses the impact of human-induced land use changes on the emergence and spread of infectious diseases. The authors highlight how activities such as deforestation, agricultural expansion, urbanization, and environmental degradation contribute to the transmission and amplification of diseases. They emphasize the complex interactions between land use changes, ecosystem modifications, and disease dynamics, particularly in the context of zoonotic pathogens. The Working Group on Land Use Change and Disease Emergence, convened at a special colloquium, developed a systems model to understand these relationships and identified priority infectious diseases affected by ecológic degradation. The group recommended creating Centers of Excellence in Ecology and Health Research and Training to address these issues, focusing on interdisciplinary research, community engagement, and policy-making for sustainable health and ecosystems. The article also outlines key research areas, policy recommendations, and the need for transdisciplinary collaboration to tackle the challenges posed by land use changes and infectious disease emergence.The article "Unhealthy Landscapes: Policy Recommendations on Land Use Change and Infectious Disease Emergence" by Jonathan A.
