The practice of climate change adaptation has an incredible opportunity to learn what is working and to improve over time. An analogy can be drawn to the field of medicine where researchers carefully study the conditions under which certain interventions are successful or not. For adaptation, this requires that communities that are planning and implementing adaptation measures monitor and report on what they have done and the outcomes that were associated with their actions. Over time, the results from this information can be used to improve the effectiveness and efficiency of adaptation, thereby saving scarce resources for communities such as yours.
