Los Angeles has some of the strictest tree planting rules in the nation. These policies limit tree growth, worsen shade disparities and don’t improve safety, researchers found. When USC Dornsife researchers modeled looser planting restrictions in a lower-income neighborhood, potential tree space increased by nearly 26%. But narrow sidewalks and dense infrastructure still limited where larger, shade trees could thrive. Many of L.A.’s strict tree-spacing rules are internal guidelines — not laws — meaning they could be updated more easily to allow for more trees. Closing L.A.’s shade gap, however, will require more than policy tweaks; infrastructure investments are also needed.
Traditional teaching methods may not fully prepare students for the digital era. A recent discussion explores how AI-driven strategies can enhance learning outcomes and engagement. It examines adaptive learning platforms, intelligent tutoring systems, and AI-assisted assessments, highlighting their role in personalizing instruction and improving student performance. By integrating these technologies, educators can reshape modern classrooms. This discussion provides insights into the transformative potential of AI in education.
Energy sector decarbonization is a key battleground in China’s march toward carbon neutrality, and understanding what it means and takes is crucial for its policy-making and sustainable implementation. Here we analyze the structural challenges and review the necessary supporting technologies and systems of energy sector decarbonization in China. This work could achieve a better understanding of technology development and deployment, and to make more thoughtful policy recommendations.
