This case study focuses on the knowledge sharing network AfricaAdapt. Knowledge sharing tools and networks relating to climate change adaptation increasingly draw on Web 2.0 functionalities and user generated content. These contribute to a shared evidence base upon which current and future adaptation planning and action can draw. They can help to build a community of practice around adaptation, validate adaptation processes and information, offer users a sense of potential options and outcomes from adaptation actions, based on others' experiences, as well as space to document their own experiences. AfricaAdapt describes its aim being "to facilitate the flow of climate change adaptation knowledge for sustainable livelihoods between researchers, policy makers, civil society organisations and communities who are vulnerable to climate variability and change across the continent".
