Three years into an ecological economics PhD in France, Ando Rabearisoa made a decision that would change both her life and Madagascar\u2019s coastal ecosystems. In 2009, she abandoned her PhD studies to move back to her home nation of Madagascar. There, inspired by some of her early research on community-based management of natural resources, she worked with fishing communities to create locally managed marine areas (LMMAs), a type of coastal conservation zone that is overseen by the communities that rely on the area\u2019s natural resources. LMMAs offer an alternative to conventional, government-managed marine protected areas, the implementation of which, in low-income countries, can lead to friction with anglers and lack proper enforcement. <\/p>\n

From 2009 to 2019, Rabearisoa led the Madagascar marine programme at Conservation International, a non-profit organization headquartered in Crystal City, Virginia, focused on environmental protection. During that time, the number of LMMAs in Madagascar swelled from 33 to 177. Now, scientists are studying how these conservation areas affect people and nature. For example, in Madagascar\u2019s first LMMA, researchers observed a 189% increase in fish biomass over a six-year period1<\/a><\/sup>.<\/p>\n

After more than a decade away from doctoral studies, Rabearisoa started a new PhD, this time researching marine conservation at the University of California, Santa Cruz. She investigated how the web of LMMAs that she helped to create is affecting fish populations and fisher incomes. Her latest study, published in 2025, surveyed communities in northeastern Madagascar and found that 95% of respondents preferred LMMAs to conventional marine conservation zones because they give local people better control of fishing rules and restrictions2<\/a><\/sup>.<\/p>\n

Madagascar has emerged as a regional model for LMMAs, in part owing to Rabearisoa\u2019s work. In 2024, the nation hosted East Africa\u2019s first-ever LMMA conference for anglers, conservationists and other stakeholders<\/a> from countries such as Kenya and Mozambique. Now a postdoctoral researcher at the University of California, Berkeley, Rabearisoa spoke to Nature <\/i>about community-based conservation, her decision to resume her PhD studies and the challenges that female scientists face in Madagascar.<\/p>\n

When did you first become interested in the environment?<\/h2>\n

Beginning when I was ten years old, my family and I would go camping in the rainforests of Madagascar. The government had created a series of national parks and my father insisted on taking the family to these brand new reserves. I distinctly remember seeing lemurs, and that made me fall in love with nature.<\/p>\n

Why did you leave academia, and why did you return?<\/h2>\n

I did my master\u2019s degree in ecological economics at the University of Antananarivo in Madagascar. I wanted to understand not just ecology, but also how to attribute value to the benefits that nature provides.<\/p>\n

After finishing my master\u2019s degree, I moved to France for a PhD in ecological economics at the University of Versailles Saint-Quentin-en-Yvelines near Paris. I was just 24 years old when I started it and I couldn\u2019t stop thinking about how difficult it is for young women to become professors, especially in Madagascar \u2014 where conventional gender roles are still prevalent. If I graduated in six years, I would be 30. I kept doubting whether anyone would want to hire a 30-year-old woman as a professor.<\/p>\n

So, I started to apply for jobs. In the third year of my PhD, Conservation International offered me a position as its marine programme manager in Madagascar. I accepted the job and moved back there. I worked for the organization for ten years and it was an incredible experience, but my friends kept urging me to finish my PhD.<\/p>\n

Eventually, I applied for a master\u2019s degree at the Coastal Science and Policy Program at the University of California, Santa Cruz, which would have served as a refresher for me. But when my adviser saw my CV, he said \u201cI want you to do a PhD\u201d. I accepted the offer, but with one condition: my research would focus on Madagascar\u2019s LMMAs.<\/p>\n

The scientific community is finally recognizing that community-based conservation works. During my PhD, I dived into the details of what makes community-based management of fisheries effective, what we can learn when it doesn\u2019t work and how we can improve it.<\/p>\n

How did LMMAs first come about in Madagascar?<\/h2>\n

LMMAs were first implemented in Fiji in the 1990s, when coastal communities created their own sustainable fishing systems. In the early 2000s, some of my colleagues took fishers from Madagascar to Fiji to study its LMMAs. The fishers said that although they didn\u2019t speak the same language as the Fijian people, they shared the common language of the ocean. They immediately understood how the system of seasonal closures and fishing restrictions in Fiji served to ensure a sustainable catch.<\/p>\n

When the fishers returned to Madagascar, they decided to create their own LMMA based on the same principles. Several years later, my colleagues and I brought fishers from other parts of Madagascar to visit the pilot LMMA so that they could take the system back to their own communities.<\/p>\n

What did you learn during your ten years at Conservation International?<\/h2>\n

In Madagascar, many people living on the coast make their living directly from the sea. Conservation efforts cannot succeed if they exclude them. LMMAs work because they give communities control over how to manage their resources.<\/p>\n

Overfishing and poverty form a vicious cycle. People fish more because they have a low income, which worsens the depletion of fish and deepens poverty. The goal of LMMAs is to break that cycle by supporting sustainable fishing, which increases long-term yields. This strategy means that front-line communities are conservationists\u2019 allies in the battle to protect the ocean.<\/p>\n

Another important lesson that I learnt is that we must adapt protected areas to the local context. Every place has a distinct ecology, culture and system of governance. A big part of my PhD looked at how to use local communities\u2019 ecological knowledge to make fishing more sustainable. For example, local communities know exactly where and when fish spawn, and we use that information to close specific areas seasonally to protect the next generation of fish.<\/p>\n<\/div>\n
