The workshop on ‘Developing criteria for classifying and assessing climate change adaptation options in the Gandaki river-basin’ was commissioned to engage relevant stakeholders in the design of a Climate Change Adaptation Matrix, get their inputs to improve the classification of adaptation options, and identify the most important criteria for policy makers and practitioners to evaluate or assess adaptation options. Participants from more than 20 different organizations in Nepal working on climate change adaptation in various sectors and at different levels were present at the workshop.
