These examples illustrate actions that people, communities, and governments are taking in response to past impacts of climate change and future vulnerabilities. Coastal protection: In response to sea level rise and storm surge in San Francisco Bay, federal, state, and local agencies, supported by voter-approved funds, are restoring coastal habitats and levees to protect cities from flooding. Crop water savings: The risk of reduced food production increases as climate change intensifies drought. In the Gila River Basin, local government agencies have lined 15 miles (24 km) of irrigation canals to reduce seepage from the canals, saving enough water to irrigate approximately 8,500 acres (3,400 hectares) of alfalfa and other crops each year. Cultural fire restoration: Reintroduction of cultural burning by the Yurok Tribe in northern California reduces wildfire risks and protects public and tribal trust resources. Desert soil restoration: In Utah, transplanting native and drought-resistant microbial communities improves soil fertility and guards against erosion. Health protection: To reduce heat-associated injury and deaths on Arizona trails, the City of Phoenix and Arizona tourism organizations developed a campaign “Take a Hike. Do it Right.” Signs at trailheads and on websites remind hikers to bring water, stay hydrated, and stay aware of environmental conditions. Ranching and habitat: The Malpai Borderlands Group in Arizona and New Mexico integrates native plant and wildlife conservation into private ranching. Rooftop solar: The state governments of California, Colorado, and Nevada have enacted policies that support rooftop solar on homes, which reduces greenhouse gas emissions, improves reliability of the electricity generation system, and creates local small businesses and new jobs. Water conservation: Drought in the Colorado River Basin has reduced the volume of water in both Lake Mead and Lake Powell by over half. The United States, Mexico, and state governments have mobilized users to conserve water, keeping the lake above a critical level. Wildfire fuel reduction: In response to severe wildfires, the City of Flagstaff, Arizona, enacted a bond to fund reduction of fire fuels in forests around the town. Source: National Park Service.
