 The Programme ensures that the Business Engagement Strategy is implemented through IUCN's global thematic and regional programmes as well as helps guide the work of IUCN's six Commissions.Nature-based Solutions (NbS) use ecosystems and the services they provide to address societal challenges such as climate change, food security or natural disasters.The emergence of the NbS concept in environmental sciences and nature conservation contexts came as international organisations, such as IUCN and the World Bank, searched for solutions to work with ecosystems rather than relying on conventional engineering interventions (such as seawalls), to adapt to and mitigate climate change effects, while improving sustainable livelihoods and protecting natural ecosystems and biodiversity.
