Developing countries are facing a significant financial shortfall in their efforts to adapt to the escalating effects of climate change, receiving less than 10 percent of the funds necessary for critical adaptation strategies, according to the recent Adaptation Gap Report released by the UN Environment Programme (UNEP). This alarming reality puts lives, livelihoods, and entire economies at serious risk as these nations grapple with the severe impacts of extreme weather linked to climate change.
To effectively respond to the expected and actual effects of climate change—referred to as “climate adaptation”—developing nations will require over $310 billion annually by 2035. Current funding levels fall drastically short, with vulnerable countries having secured approximately $26 billion in 2023 for essential adaptation projects that include flood defenses and enhanced drainage systems.
UN Secretary-General António Guterres highlighted the dire repercussions of the adaptation gap, warning that it exposes the world’s most vulnerable populations to rising sea levels, increasingly severe storms, and extreme heat. He emphasized that “adaptation is not a cost – it is a lifeline,” advocating for immediate action to close the funding gap to protect lives and facilitate climate justice.
While the report underscores the urgency of the situation, it also notes some progress in the climate adaptation landscape. A majority of countries have established at least one national adaptation plan, and funding for new adaptation projects has risen in 2024, although future financial stability remains uncertain due to the current economic climate.
These findings will inform discussions at the upcoming annual UN Climate Conference, COP30, set to take place in Belém, Brazil, where the critical issue of financing for developing nations is expected to be a focal point. Last year, COP29 introduced the ambitious Baku to Belém Roadmap, which aims to mobilize $1.3 trillion in climate finance from public and private sources by 2035, targeting both adaptation efforts and a transition away from fossil fuel-dependent economies.
The authors of the Adaptation Gap report caution that while the roadmap is a potentially transformative initiative, the effectiveness will depend on a commitment to provide grants rather than loans, as loans could further constrict the financial capabilities of already vulnerable nations. UNEP Executive Director Inger Andersen called for an urgent global effort to boost adaptation financing without exacerbating the debt burdens of developing countries.
In a parallel report, the World Health Organisation (WHO) revealed the grim health toll associated with climate inaction, noting an increase in heat-related deaths and growing food insecurity exacerbated by climatic conditions. Despite mounting evidence of the substantial economic and health consequences of inaction, governments still allocated a staggering $956 billion toward fossil fuel subsidies in 2023, overshadowing the funds directed toward climate resilience.
Experts emphasize that immediate investment in adaptation strategies and sustainable agricultural systems is crucial to mitigating these effects and could potentially save millions of lives annually. Organizations around the world are demonstrating that transformative change is attainable through local innovations in clean energy and climate adaptation, reinforcing the importance of collective global action in addressing the climate crisis.
This critical juncture presents both challenges and opportunities for nations to unite and embark on a path toward sustainable, equitable solutions in the face of climate change. The road to recovery and resilience is marked by collaboration, funding, and innovative strategies; the potential for progress remains within reach if substantial actions are taken now.
