Final answer:
Planning to manage increasing drought conditions in a Western US agricultural region is an example of Climate change adaptation, which involves implementing measures to cope with climate impacts like drought and enhancing the adaptive capacity of communities.
Step-by-step explanation:
Planning to manage increasing drought conditions in a Western US agricultural region is an example of Climate change adaptation. This approach involves implementing policies and practices to cope with the effects of climate change, such as conservation of water through rainwater harvesting, water re-use, and increased irrigation efficiency. Moreover, it encompasses enhancing the adaptive capacity of communities, especially smallholder farmers, to ensure food security and sustainable development in the face of climate variability. On the other hand, climate change mitigation refers to efforts to reduce or prevent the emission of greenhouse gases, aiming at slowing down global warming.
Climate resilience building and climate modeling are also important strategies. Resilience building focuses on strengthening the ability of systems to recover from climate-related disturbances, while climate modeling involves using computational techniques to predict and analyze climate patterns and inform decisions.
Answer: A. Climate change adaptation
