CAMBRIDGE, England — Dr. Constance Abiodun, one of the world’s most cited researchers in the field of climate adaptation, rarely gives long interviews. When she does, she tends to sit very still, speak in precise sentences, and decline, politely but firmly, to offer predictions she considers unsupported by evidence. The conversation that follows is drawn from four hours of discussion conducted across two days at her office at a research institute here, and from a subsequent exchange of written questions she answered with the same deliberateness she applies to her scientific papers.
Abiodun, 58, grew up in Lagos, the third of five children, and came to climate science by way of agricultural economics, a career shift she describes as less a conversion than a recognition that the questions she actually cared about lay upstream of the ones she had been trained to ask. Her doctoral research, completed at a Dutch university in the late 1990s, examined how subsistence farmers in West Africa adjusted planting decisions in response to shifting rainfall patterns. It was, she says, the moment she understood that climate change was not a future threat but a present re-organisation of the world that millions of people were already navigating without policy support, scientific guidance, or public attention.
“The farmers I interviewed were not waiting for a report,” she said. “They were watching the sky, talking to their parents about what it used to look like, and making choices. They were doing adaptation science with the tools they had. My job, as I came to understand it, was to make their knowledge legible to the institutions that could actually allocate resources.”
Her subsequent career spanned positions at institutions in Nigeria, Germany, and the United Kingdom, accumulating a body of work focused less on modelling future climate states than on documenting and systematising the adaptation responses of communities already living with extreme heat, flood cycles, and shifting agricultural seasons. Her 2019 synthesis paper, which reviewed adaptation strategies across 230 community-level studies in sub-Saharan Africa and South Asia, has been cited more than 4,000 times and is widely credited with shifting international climate finance discussions toward ground-level, community-led responses.
She is measured when asked about the pace of international climate policy. She does not use words like failure or betrayal. She describes instead a structural mismatch between the timescales on which political systems operate and the timescales on which climate impacts compound, and she suggests, with the careful tone of someone who has made the same observation many times to audiences who found it uncomfortable, that this mismatch is not an accident but a feature of how modern governance was designed.
“National election cycles are typically four or five years,” she said. “The consequences of a decision made today about infrastructure, land use, or emissions policy may not be politically visible for 20 or 30 years. That is not a bug. That is how democratic accountability was structured. It is also, plainly, inadequate for the challenge we are in.”
Asked whether she is optimistic, she pauses for long enough that the question begins to feel unanswerable. Then she says that optimism and pessimism are not categories she finds useful. What she finds useful, she says, is evidence. And the evidence, as she reads it, shows both that the window for preventing the worst outcomes is narrowing and that adaptation capacity in many vulnerable communities has proven more robust and creative than researchers, including herself, expected 20 years ago.
“People adapt,” she said. “They always have. The question is whether they are forced to adapt alone, with whatever is at hand, or whether we build systems that support and distribute that capacity equitably. That is a choice. It is not a scientific question. It is a political one.”
Her current research centres on what she calls the second generation of adaptation challenges: not the first responses that communities make to changing conditions, but what happens when those initial responses are themselves overtaken by further change, a compounding process she argues is insufficiently studied and likely to define the climate experience of the next two decades in many parts of the world. She is characteristically reluctant to summarise the findings before they are published. But she allows that the picture is more complex than the linear adaptation narratives that dominate policy discussions, and that it will require policy frameworks that are themselves capable of learning and revising in real time.
“We are not building a wall against a fixed flood,” she said. “We are learning to live in a river that is changing its course. The thinking has to change along with it.”
