Biocultural Sustainability in Madagascar (2022-2023)
For millennia, people have subsisted via “traditional” lifestyles, each generation meeting their needs without creating adverse consequences for future generations. In contrast, industrialized nations and globalized supply chains have exhausted natural resources, driving the loss of biological and cultural diversity and diminishing the ecosystem services on which we all depend. The environmental crisis is linked to a global health pandemic, as a billion people worldwide lack adequate access to safe, nutritious food. To achieve the United Nations’ sustainable development goals, it is crucial to understand the mechanisms and processes that maintain diversity of species.
In Madagascar, a global hotspot for both biodiversity and extinction, millions of people depend on local natural resources for their livelihoods. People harvest trees from the forest to build their homes and hunt wildlife. Although those practices may be sustainable to varying degrees, the current rate of forest loss and hunting endanger thousands of species, like the iconic lemurs, while millions of people face challenges of food insecurity, malnutrition and poverty. Therefore, there must be a balance between biodiversity conservation and the livelihoods of local people who depend on the land.
This project team will examine the sustainability of the current livelihood strategies of forest frontier communities in Madagascar and develop strategies for transition toward sustainable lifestyles.
The team will test the hypothesis that the lemur and tree populations surrounding forest frontier communities will be sustained, given current livelihood strategies and natural resource management. Team members will examine the feedbacks among farming and forest use practices, socioeconomics, food insecurity and nutritional health. Collaborating with local landowners and forest managers, researchers at the regional university and the Duke Lemur Center, the team will develop a strategic action plan to diversify livelihood opportunities and preserve forest resources.
Team members will study the field research data from Madagascar using population viability analysis to infer the extinction risk of lemur and tree populations given abundance, demographics and harvest rates. They will participate in peer-to-peer exchange with Malagasy collaborators, with each subgroup presenting their progress on independent projects and receiving feedback from the team.
