Adapting water management and agricultural practices to climate variability is essential and requires integrated responses. This brief explores how countries can harness south-south and triangular cooperation for accelerating the exchange of adaptation technologies, knowledge and practices in the water and agriculture sectors. It also highlights challenges, best practices, lessons learned, and the roles of stakeholders in replicating and transferring such technologies. The brief is set in the context of country efforts to implement their national adaptation plans, nationally determined contributions and the sustainable development goals.
