Two distinguished researchers from the University of the West Indies (UWI) are spearheading a groundbreaking initiative to channel concessional climate finance to small developing states, including Barbados, under a One Health climate-resilience framework. Dr. Kirk Douglas, Director of the Centre for Biosecurity Studies at UWI Cave Hill, and Dr. Preeya Mohan, a climate-finance economist at UWI’s St. Augustine Campus in Trinidad, are collaborating to design a novel climate-finance architecture. This initiative aligns with the Bridgetown Initiative, aiming to support low- and middle-income countries (LMICs) and Small Island Developing States (SIDS) in building resilience against climate change. The One Health approach emphasizes the interconnectedness of human, animal, and environmental health, fostering sustainable practices, enhancing early warning systems, and creating robust health systems to mitigate risks like zoonotic diseases, food insecurity, and antimicrobial resistance. The Bridgetown Initiative, led by Barbados, calls for urgent reforms to the outdated international financial architecture, which fails to address contemporary challenges such as climate risks and social inequalities. Dr. Douglas, a delegate at the recent World Organisation for Animal Health Global Conference in Geneva, highlighted the critical need for a paradigm shift in climate-resilient financing. He stressed that One Health events should be recognized as climate events within climate finance frameworks, addressing the pervasive impacts of infectious diseases, vector-borne diseases, and plant health emergencies. This innovative approach aims to bridge the gap in funding and resonate with global financial stakeholders, ensuring a sustainable and resilient future for vulnerable nations.
