In this final seminar of the series, Professor Kennel discusses the essential role of assessment in the adaptive management of complex systems; the regional specificity of climate change impacts; the critical role of local communities; the complexity of knowledge assembly for regional and local decision‐support; and the need to encourage timely decisions. “Knowledge Action Networks” comprising international experts and local decision‐makers can foster informed and timely decisions at the regional and local levels.
