The Global Center on Adaptation Has a New CEO. Rebuilding It Will Take More Than That

When the Global Center on Adaptation announced that Madagascar's Rindra Rabarinirinarison would take the helm as its new CEO, the appointment carried symbolic weight that was hard to ignore. A leader from one of the world's most climate-vulnerable nations stepping into an organization whose entire mandate is to help countries adapt to a warming planet — there is a certain logic to that. But symbolism alone does not fix a troubled institution, and the GCA arrives at this leadership transition carrying significant institutional baggage.

Founded in 2018 and headquartered in Rotterdam, the GCA was conceived as a high-profile bridge between climate science and policy, with former United Nations Secretary-General Ban Ki-moon serving as its board chair. It attracted serious early attention and donor funding, positioning itself as a convening force for adaptation finance at a moment when the global conversation was finally beginning to shift from mitigation alone toward the harder, messier work of living with climate change. But in recent years, the organization has struggled. Donor confidence has eroded, its mission has appeared diffuse to critics, and questions about governance and financial management have surfaced in ways that made funders nervous.

Rabarinirinarison, who previously served in Madagascar's environment sector, has been explicit about her priorities: fundraising, rebuilding trust with donors, and sharpening the GCA's focus. These are not small tasks. Rebuilding institutional credibility after a period of turbulence is notoriously difficult, particularly in the climate finance space where donor governments are themselves under domestic political pressure to justify international spending. The window for making that case is narrowing.

The GCA's difficulties are not entirely unique. Adaptation-focused institutions occupy an awkward structural position in the broader climate architecture. Mitigation — reducing emissions — has clearer metrics, more established financial instruments, and a larger constituency of private sector actors who see profit potential in clean energy transitions. Adaptation, by contrast, is fundamentally about reducing losses rather than generating returns. A sea wall does not produce revenue. Drought-resistant seeds do not attract venture capital at scale. This makes adaptation chronically underfunded relative to need, and it makes organizations working in this space perpetually dependent on the goodwill of donor governments rather than diversified funding streams.

The UN Environment Programme has repeatedly documented this gap. Its Adaptation Gap Report found that adaptation finance flows to developing countries remain far below what is needed, with estimates suggesting the annual shortfall runs into the hundreds of billions of dollars. Into this environment, the GCA was supposed to inject urgency and coordination. Whether it succeeded in doing so before its internal difficulties mounted is a question donors are now quietly asking.

There is also a mission clarity problem that has plagued adaptation institutions broadly. When an organization tries to be a research hub, a policy convener, a fundraising platform, and a project implementer simultaneously, it risks doing none of those things particularly well. Rabarinirinarison's stated intention to hone the GCA's mission suggests she recognizes this tension. The harder question is which functions get prioritized and which get quietly deprioritized — and whether the donors who funded specific programs will accept that recalibration.

The fate of the GCA matters beyond its own institutional survival. It sits at a moment when adaptation finance is finally receiving rhetorical commitment from wealthy nations, including through the new loss and damage fund established at COP27 and operationalized at COP28 in Dubai. If the GCA can stabilize and reestablish credibility, it could serve as a meaningful conduit and advocate as those funds begin to flow. If it continues to struggle, it risks becoming a cautionary tale that skeptics use to argue against multilateral climate institutions more broadly — a narrative that would do real damage at precisely the wrong moment.

There is also a subtler feedback loop worth watching. Rabarinirinarison's background in Madagascar, a country that ranks among the most exposed to climate impacts anywhere on earth, could genuinely shift the GCA's center of gravity toward frontline perspectives. Or it could remain largely cosmetic if the organization's governance structures and donor relationships continue to be shaped primarily by European institutional norms. Which of those outcomes materializes will depend less on the CEO's intentions than on whether the board and major funders are willing to genuinely share decision-making power with the Global South voices they have long claimed to center.

The GCA's next funding cycle will be the real test. Speeches and strategic plans are easy. Convincing a skeptical donor government to write a large check to an organization that has recently disappointed them is something else entirely — and that conversation is already underway.
