Drought, unpredictable rains, and changing seasons have brought the harsh reality of climate change to those communities - and now adaptation is not choice, but a necessity.
THINK NATIONALLY, ACT LOCALLY
The new research looked at the capacity of institutions to influence and share knowledge about climate change in Cameroon's often remote areas.
"You can't rely on individual knowledge and effort to tackle climate change, because capacity is so limited," says CIFOR senior scientist Denis Sonwa, who is based in Yaoundé.
"So we looked at the government and NGOs, as well as informal organizations, like farmers' cooperatives and savings groups, to see what is being done, and could be done by them."
Institutions have long been identified as critical to people's ability to adapt to climate change, not just because they can act like a safety net, but for their ability to foster social learning, innovation and problem solving.
