Flooding and land use change in Jambi Province, Sumatra: integrating local knowledge and scientific inquiry

The rapid expansion of rubber and oil palm plantations in Jambi Province, Sumatra, Indonesia, is associated with large-scale deforestation and the impairment of many ecosystem services. According to villagers' observations, this land use change has, together with climate change, led to an incre...
