Whether it’s impacts from deteriorating air quality, the spread of disease from rising temperatures and humidity, down to the psychological impacts of losing homes and forced migration, climate change is proving to be not just an environmental crisis, but a human health problem, too.
And, with the increasing frequency of heatwaves, flooding, droughts, and severe weather events, the need to address the impact on humans is also increasing.

Hurricane Milton and climate change: A wake-up call ahead of COP29
Rising temperatures and air pollution are, for instance, detrimental to our lungs, hearts, and brains. Vulnerable groups such as the elderly and infants are particularly affected during heatwaves, which can cause physiological changes in circulation and heart function.
In another example, flooding in southern New South Wales and northern Victoria led to increased mosquito breeding and changes in bird migration patterns, resulting in an outbreak of Japanese encephalitis.
The Indo-Pacific impact
In Makassar, annual flooding displaces thousands, destroys properties, and forces people into temporary shelters. This disrupts education, healthcare access and food supply, with contaminated farming areas exacerbating the situation.

Pacific Islanders, too, face drastic health impacts from climate change. Cyclones and rising sea levels affect access to nutritious food by damaging croplands and affecting fish quality and soil. Mental health issues such as PTSD, adjustment disorders and depression are also prevalent due to the stress and cultural changes from displacement.
What’s being done now?
Efforts to mitigate climate change include reducing emissions. One way being explored is to use microbes to remove climate-active gases from the atmosphere, including reducing methane emissions from cattle, which can enhance both sustainability and productivity.
Innovative solutions such as green infrastructure are being designed to address environmental health issues in informal settlements. This involves treating household wastewater before releasing it into the environment, improving health in the Asia-Pacific region.
Communities in the Pacific are building resilience by reviving traditional practices, such as sustainable boatbuilding, setting up coral restoration sites, and restoring mangrove populations.
