African societies face growing global change risks, with rapidly changing patterns of human settlements and intensity of use of ecosystem services. At the same time, climate variability and climate change trends are intensifying stress on the ecosystems that ensure environmental security, both locally (e.g. ecosystem services), regionally (e.g. sustainable development options) and internationally (e.g. carbon sequestration).


Approaches that can address this challenge in an integrated and multidisciplinary way are urgently needed in many places in Africa where there is a close relationship between societal well-being and environmental condition, relating particularly to biomass for energy and food production, and hydrological considerations such as water yields. Policymakers and land-use decision makers are increasingly dependent on knowledge on the state of the environment. Long-term observational systems and research infrastructures have been identified to be indispensable elements of knowledge generation to serve climate change adaptation, food security, and climate change mitigation.
