The burden on those directly affected by climate change can be eased by spreading or sharing losses , perhaps through government disaster relief. Sometimes it may be best to restore a site , such as an historical monument newly vulnerable to flood damage. Successful strategies will draw on ideas and advances in law, finance, economics, technology, public education, and training and research. Technological advances often create new options for managed systems such as agriculture and water supply. However, many regions of the world currently have limited access to new technologies and to information.
Technology transfer is essential, as is the availability of financial resources.
Cultural, educational, managerial, institutional, legal, and regulatory practices are also important to effective adaptation, at both the national and international levels. For example, the ability to incorporate climate change concerns into development plans can help ensure that new investments in infrastructure reflect likely future conditions. Many adaptation policies would make good sense even without climate change. Present-day climatic variability, including extreme climatic events such as droughts and floods, already causes a great deal of destruction. Greater efforts to adapt to these events could help to reduce damage in the short term, regardless of any longer-term changes in climate.
