As the effects of climate change increasingly challenge progress towards development goals, national-level frameworks that monitor and evaluate both adaptation and development are needed to allow developing countries to prioritise investment most effectively. Cambodia is using IIED’s Tracking Adaptation and Measuring Development (TAMD) approach to facilitate its national M&E framework. The TAMD approach evaluates the success of climate change responses by combining how widely and how well countries or institutions manage climate risks with how successful adaptation actions are in reducing climate vulnerability and encouraging development. Using an innovative readiness ladder approach has also allowed measurement of progress towards adaptation and development goals. Cambodia’s pioneering approach can serve as an example to other developing countries as they develop their national M&E systems for climate change interventions.
