Description
Y02A encompasses technologies and applications designed to help human systems and natural environments adapt to the effects of climate change, including impacts already occurring or expected. This subclass covers innovations such as drought-resistant agriculture, flood management systems, climate-resilient infrastructure, water conservation technologies, and ecosystem protection measures. It includes adaptations across sectors like agriculture, water resources, construction, and disaster management where the primary purpose is reducing vulnerability to climate impacts rather than mitigating greenhouse gas emissions. Related mitigating technologies (focused on reducing climate change causes) are classified under Y02.
