Climate change and the public health imperative for supporting migration as adaptation.

In an era of accelerating global climate change, human mobility has reached unprecedented levels. While it is acknowledged that many cases of human migration in the context of climate change are forced or involuntary, particularly where adaptation measures have failed to achieve sufficient resiliency of communities against impending slow- and sudden-onset disasters. There are also many cases where migration is, itself, a voluntary adaptive measure to secure otherwise unattainable physical safety and life-sustaining resources. It is in these cases that migration can be viewed as adaptation. Under the right policy conditions, it is possible for such adaptive migration to save countless lives. Moreover, it can achieve remarkable health and well-being gains for otherwise vulnerable communities residing on environmentally degrading lands and disproportionately suffering from the health impacts of climate change. While several activists have spoken loudly on the topic of climate migration, emphasizing the human rights imperative for supportive global policy action, the public health community has not been equally vocal nor unanimous in its stance. This paper, a product of the World Federation of Public Health Associations (WFPHA) Environmental Health Working Group, aims to rectify this gap, by analyzing adaptive climate migration through a public health lens. In doing so, it argues that creating an enabling environment for adaptive climate migration is not just a human rights imperative, but also a public health one. This argument is supported by evidence demonstrating how creating such an enabling environment can synergistically support the fulfillment of key public health services and functions, as outlined under the internationally endorsed Global Charter for the Public's Health of the WFPHA.

Barriers to Climate Disaster risk Management for Public Health: Lessons from a Pilot Survey of National Public Health Representatives.

OBJECTIVES: This study sought to examine current national disaster risk management capacities, and identify governance barriers to strengthening national preparedness for responding to public health emergencies, associated with the anticipated climate-driven intensification of natural disaster cycles. METHODS: A mixed-methods online survey, assessing broader governance constraints to climate change adaptation (CCA) for public health, was distributed to representatives of national public health associations, and societies of 82 member countries under the World Federation of Public Health Associations. Specific questions relevant to disaster risk management capacities and barriers were analyzed as part of a narrowed focus on the CCA subdomain of emergency preparedness. RESULTS: Existence of some technology, infrastructure, and/ or human resources, necessary to develop early warning and other surveillance systems for climate-related health risks was reported by 9 out of 11 responding countries. However, 7 reported persistent limitations and/ or regional discrepancies. Most significant identified barriers to strengthening emergency preparedness at the national level included governance coordination challenges, and, in the case of many developing countries, technical, medical, and human resource shortages. CONCLUSIONS: The development of new frameworks for intersectoral governance and large-scale resource mobilization will prove crucial to ongoing efforts to strengthen national climate-health resiliency and prepare for disaster-associated health threats.

Drought, drying and climate change: emerging health issues for ageing Australians in rural areas.

Older Australians living in rural areas have long faced significant challenges in maintaining health. Their circumstances are shaped by the occupations, lifestyles, environments and remoteness which characterise the diversity of rural communities. Many rural regions face threats to future sustainability and greater proportions of the aged reside in these areas. The emerging changes in Australia's climate over the past decade may be considered indicative of future trends, and herald amplification of these familiar challenges for rural communities. Such climate changes are likely to exacerbate existing health risks and compromise community infrastructure in some instances. This paper discusses climate change-related health risks facing older people in rural areas, with an emphasis on the impact of heat, drought and drying on rural and remote regions. Adaptive health sector responses are identified to promote mitigation of this substantial emerging need as individuals and their communities experience the projected impact of climate change.
