Regional Climate Change Adaptation Based on the PSR model ——Multi-case Comparative Analysis on a Global Scale

Abstract

Regional climate change is affected by global warming, large-scale inter-regional circulation and land use/cover. As a result of different ecological, economic, and social conditions, climate adaptation actions vary from region to region. Based on the pressure-state-response model, this paper uses a combination of multi-case comparative analysis and content analysis to conduct a comparative analysis of five typical regional cases of climate change adaptation around the world. It found that: (1) The pressure to regional climate change adaptation refers to the movement of elements such as finance, population and species across regions. (2) The status is based on regional climate change predictions. (3) The response is two-fold, one being develop a hot map of climate change to assess regional climate vulnerability; the other is to take advantage of decision making and implementation by actively promoting horizontal and vertical cooperation in multi-level governance. In the future, regional climate adaptation will focus on inter-regional climate justice, regional climate change adaptation pathways optimization, and how to effectively learn from typical regional climate adaptations.
