Vulnerability and Adaptation to Climate Change: Agricultural Systems in Madagascar

April 21, 2016

Madagascar, the world’s fourth largest island, is home to an astonishing range of life forms found nowhere else on the planet. Much of this biodiversity is highly vulnerable to climate change. So too are the rainfed agriculture, fishing, and forestry that sustain the island’s 20 mil­lion people.

Decision-makers implementing Madagascar’s national action plan on climate change adapta­tion have lacked precise information on the spatial dimensions of vulnerability to climate change – knowing to what factors people and resources are vulnerable, and where. A project led by Mada­gascar’s University of Antananarivo is looking at vulnerability and adaptation options in the island’s agricultural sector. Building on its research so far, the team was invited to contribute text on the vulner­ability of agrarian systems to Madagascar’s second National Communication under the United Nations Framework Convention on Climate Change.

As well as improving information on climate change vulnerabilities, the project is facilitating dialogue between at-risk groups, decision-makers, and researchers. Reflection groups set up at local and regional levels in 2008–09 enable exchanges on both vulnerability and strategies for reducing risk, and the project is in the process of producing a range of vulnerability studies and maps. Seven local reflection groups linking researchers and local people have been established. Each group is made up of 20 men and women, representing different agricultural sectors.

In a first series of seven local workshops, people shared their perceptions of climate change and its impacts on agricultural systems. By and large, across the groups, rural representatives see a clear distinc­tion between the climate ‘then’ and ‘now’. Some see change occurring progressively, while others perceive radical shifts following milestone events such as violent cyclones. Farmers see environmental degradation as the underlying cause – rapid defor­estation in particular. Other rural people attribute the changes to a lack of respect for traditional values. They also note negative effects on traditional knowledge, which is seen as losing its sacred power. In the Alaotra region, for example, people testified that local ‘witches’ used to be able to make the rains come at will, but can no longer.

Gaining a better understanding of local perceptions of climate change is just one element of the team’s effort to paint a composite map of climate vulnerability and risk to agrarian systems. These reflection groups validate local experiences, while allowing researchers to share findings with communities on biophysical and other observed and measurable changes. To bring policymakers into the equation, and scale up the dialogue, reflection groups are being established at regional level linking decision-makers, support groups working on climate change and agriculture, and representatives from the seven local reflection groups. Ultimately, this improved, shared understanding of vulnerability will allow researchers to develop adaptation strategies that respond to the risks and priorities identified by community members.​
