Health workers are already being transformed by climate change. COP29 stakeholders can either support this transformation to strengthen health systems, or risk watching the health workforce collapse under mounting pressures.
The World Health Organization’s “COP29 Special Report on Climate Change and Health: Health is the Argument for Climate Action“ highlights the health sector’s role in climate action.
Health professionals are eyewitnesses and first responders to climate impacts on people and communities firsthand – from escalating respiratory diseases to spreading infections and increasing humanitarian disasters.
The report positions health workers as “trusted members of society” who are “uniquely positioned” to champion climate action.
The context is stark: WHO projects a global shortage of 10 million health workers by 2030, with six million in climate-vulnerable sub-Saharan Africa. Meanwhile, our communities and healthcare systems already bear the costs of climate change through increasing disease burdens and system strain.
Health workers are responding, because they have to. Their daily engagement with climate-affected communities offers insights that can strengthen both health systems and climate response – if we learn to listen.
A “fit-for-purpose” workforce requires rethinking learning and leadership
WHO’s report acknowledges that “scale-up and increased investments are necessary to build a well-distributed, fit-for-purpose workforce that can meet accelerating needs, especially in already vulnerable settings.” The report emphasizes that “governments and partners must prioritize access to decent jobs, resources, and support to deliver high-quality, climate-resilient health services.” This includes ensuring “essential protective equipment, supplies, fair compensation, and safe working conditions such as adequate personnel numbers, skills mix, and supervisory capacity.”
Resources, skills, and supervision are building blocks of every health system.
They are necessary but likely to be insufficient.
Such investments could be maximized through cost-effective, scalable peer learning networks that enable rapid knowledge sharing and solution development – as well as their locally-led implementation.
The WHO report calls for “community-led initiatives that harness local knowledge and practices.”
Our analyses – formed by listening to and learning from thousands of health professionals participating in the Teach to Reach peer learning platform – suggest that the expertise developed by health professionals through daily engagement with communities facing climate impacts is key to problem-solving, to implementing local solutions, and to ensure that communities are part and parcel of such solutions.
Why move beyond seeing health workers as implementers of policies or recipients of training?
We stand to gain much more if their leadership is recognized, nurtured, and supported.
This is a notion of leadership that diverges from convention: if health workers have leadership potential, it is because they are uniquely positioned to turn what they know – because they are there every day – into action.
Peer learning has the potential to significantly accelerate progress toward country and global goals for climate change and health.
By making connections, a health professional expands the horizon of what they are able to know.
At the Geneva Learning Foundation, we have seen that such leadership emerges when health workers are empowered to:
- share and validate their experiential knowledge;
- develop, test, and implement solutions with the communities they serve, using local resources;
- connect with peers facing similar challenges; and
- inform policy based on ground-level realities.
Working with a global community of community-based health workers, we co-developed the Teach to Reach platform, community, and network to listen and learn at scale. Unlike traditional training programs, Teach to Reach creates a peer learning ecosystem where:
- Health workers from over 70 countries connect directly to share experiences.
- Solutions are crowdsourced from those closest to the challenges.
- Knowledge flows horizontally rather than just vertically.
- Local innovations are rapidly shared and adapted across contexts.
For example, in June 2024, over 21,000 health professionals participated in Teach to Reach 10, generating hundreds of real-world stories and insights about climate change impacts on health.
The platform has proven particularly valuable in fragile contexts and resource-limited settings, where traditional capacity building approaches often struggle to reach or engage health workers effectively.
This approach does not replace formal institutions or traditional scientific methods – instead, it creates new pathways for knowledge to flow rapidly between communities, while building the collective capacity needed to respond to accelerating climate impacts on health.
Already, this demonstrates the untapped potential for health workers to contribute to our collective understanding and response.
But we do not stop there.
As we count down to Teach to Reach 11, participants are now sharing how they have actually used and applied this peer knowledge to make progress against their local challenges.
They cannot do it alone.
This is why we ask global partners to join and contribute to this emergent, locally-led leadership for change.
How different is this ‘ask’ from that of global partners asking health workers to contribute to the climate change and health agenda?
WHO’s COP29 report makes a powerful case that “community-led initiatives that harness local knowledge and practices in both climate action and health strategies are fundamental for creating interventions that are both culturally appropriate and effective.”
Furthermore, it recognizes that “these initiatives ensure that climate and health solutions are tailored to the specific needs and realities of those most impacted by climate change but also grounded in their lived realities.”
What framework for collaboration?
The path forward requires what the report describes as “cooperation across sectors, stakeholders and rights-holders – governmental institutions, local authorities, local leaders including religious authorities and traditional medicine practitioners, NGOs, businesses, the health community, Indigenous Peoples as well as local communities.”
Our experience with Teach to Reach demonstrates how such cooperation can be facilitated at scale through digital platforms that enable peer learning and knowledge sharing. Key elements include:
- a structured yet flexible framework for sharing experiences and insights;
- direct connections between health workers at all levels of the system;
- rapid feedback loops between local implementation and broader learning;
- support for health workers to document and share their innovations; and
- mechanisms to validate and spread effective local solutions.
WHO’s recognition that health workers have “a moral, professional and public responsibility to protect and promote health, which includes advocating for climate action, leveraging prevention for climate mitigation and cost savings, and safeguarding healthy environments” sets a clear mandate.
This WHO report highlights the need for new ways of supporting community-led learning and action to:
- support the rapid sharing of local solutions;
- build health worker capacity through peer learning;
- connect communities facing similar challenges; and
- enable health workers to lead change in their communities
