GC42A:
Global Change Impacts in West Africa: From Observations and Models to Adaptation Measures I


Session ID#: 10352

Session Description:
West Africa is characterized by a strong dependence on rain-fed agriculture and a low adaptive capacity, making it one of the most vulnerable regions to climate change worldwide. Moreover, climate models show particularly high uncertainties of anticipated future changes. Therefore, the development and implementation of sound knowledge, reliable future scenarios and appropriate adaptation measures constitute an eminent task for science, policy, and stakeholders.We invite contributions from all related disciplines that 1) document and understand the changes and their feedbacks in the biophysical and human systems in the West Africa, 2) make predictions and develop scenarios of the changes at local or regional scales through models and data, 3) assess the impacts for the environment and human development, or 4) provide appropriate adaptation measures and management tools to minimize the negative impacts and to maximize the resilience of the system to all anticipated consequences of global changes in West Africa.
