![]() For natural systems, humans may intervene to help adjustment. ![]() So adaptation may include measures to increase preparedness and relevant disaster response capacities.įor humans, adaptation aims to moderate or avoid harm, and to exploit opportunities. Scientists forecast climate change will increase the frequency and severity of extreme weather events and disasters. ![]() Global risks like climate change are having major impacts everywhere. Disasters, economic loss and the underlying vulnerabilities that drive risk are increasing. But they are always linked to human action or inaction or rooted in anthropogenic processes. In turn, disaster risk reduction is part of the broader consideration of sustainable development.ĭisasters are often triggered by natural hazards. So experts sometimes see climate change adaptation as one of many processes within disaster risk reduction. Disaster risks, response and preparedness įurther information: Disaster response § Disaster response technologies, and Disaster risk reductionĬlimate change contributes to disaster risk. The average rainfall in an area might not be as important as how frequent and severe droughts and extreme precipitation events become. That is because a storm surge can cause flooding. For example, the average sea level in a port might not be as important as the height of water during a storm surge. Many negative effects of climate change involve changes in extremes or the way conditions vary rather than changes in average conditions. The projected and observed negative impacts of climate change are sometimes referred to as the climate crisis. The effects of human-caused climate change are broad and far-reaching, especially if significant climate action is not taken. These in turn impact nature and wildlife, as well as human settlements and societies. Changes in the climate system include an overall warming trend, more extreme weather and rising sea levels. The economic costs of adaptation to climate change are likely to cost billions of dollars annually for the next several decades.Ĭlimate change affects the physical environment, ecosystems and human societies. : 20 : 130 However, adaptation also has to anticipate future risks of climate change. The extent of implemented adaptation actions is below what is needed to manage risks at current levels of climate change. This is an important step for countries to scale up the implementation of adaptation. Developing countries can receive support with international funding to help them develop national adaptation plans. Adaptation planning is also now found in subnational government, sectors and cities. Plans, policies or strategies are in place in more than 70% of countries. Adaptation needs are high for food, water and other sectors that are important for economic output, jobs and incomes.Īdaptation planning is an important activity to help countries manage climate risks. Adaptation is especially important in developing countries since those countries are most vulnerable to climate change and are bearing the brunt of the effects of climate change. The need for adaptation varies from place to place, depending on the risk to human or ecological systems. ![]() Adaptation actions can be grouped into four categories: Infrastructural and technological institutional behavioural and cultural and nature-based options. Many adaptation measures, strategies or options exist and are used to help manage impacts and risks to people and nature. ![]() For humans, adaptation aims to moderate or avoid harm, and exploit opportunities for natural systems, humans may intervene to help the adjustment.

Adapting to climate change involves structural, physical, social and institutional approaches. ![]()
