Climate adaptation research focuses on how societies, ecosystems and economies can adjust to current and future climate impacts while limiting damage and exploiting potential benefits. It distinguishes adaptation from mitigation: mitigation reduces greenhouse gas emissions, whereas adaptation manages the consequences of a changing climate already underway.

A core theme is climate risk, defined as the interaction of climate hazards with exposure and vulnerability. Hazards include heatwaves, floods, droughts and sea level rise. Exposure captures where people, assets and ecosystems are located, while vulnerability reflects sensitivity and capacity to cope. Effective adaptation strategies target all three components by reducing exposure, lowering vulnerability and sometimes moderating the hazard itself.

Research highlights diverse adaptation options. In cities, cooling strategies such as green spaces, reflective surfaces and improved building design reduce heat stress. In coastal zones, measures range from hard infrastructure like sea walls to nature based solutions such as restoring dunes, wetlands and mangroves. In agriculture, changing crop varieties, irrigation practices and planting dates helps maintain yields under shifting rainfall and temperature patterns. Water management approaches such as reservoir operation, groundwater recharge and demand management address drought and flood risks.

An important finding is that adaptation is context specific. Social, economic and institutional conditions shape what is feasible, effective and equitable. Studies stress the risk of maladaptation, where poorly designed measures increase vulnerability or harm ecosystems. For example, overreliance on air conditioning can raise emissions and exacerbate power failures during heatwaves.

Current research emphasizes integrating adaptation into broader development planning, tracking progress with indicators and ensuring that adaptation pathways remain flexible as climate risks and knowledge evolve.
