Various adaptation options are currently feasible and effective at reducing climate impacts in different socio-cultural, economic and geographical contexts , but some lack adequate economic or institutional feasibility or information on limits . Feasible and effective options include cultivar improvements, community-based adaptation, agricultural diversification, climate services, adaptive eco-management in fisheries and aquaculture. There is limited evidence, medium agreement on the institutional feasibility or cost effectiveness of adaptation activities, and the limits to such adaptations.
