Encore: Beijing's plan to save the Great Wall

Beijing’s new Great Wall Protection Regulation, effective March 1st, establishes a comprehensive legal framework to safeguard the 21,000-kilometer landmark through enhanced regional coordination and technological integration. Beyond physical restoration, the initiative addresses complex conservation challenges, including climate-induced erosion, invasive vegetation, and human-caused damage from tourism and illegal activity. Advanced monitoring tools, such as satellite imagery, thermal-imaging drones, and electronic fencing, now provide real-time data on structural integrity and crowd density, significantly improving upon traditional manual patrols. By balancing heritage preservation with public access, the regulation aims to create a sustainable management model that could eventually expand to other national heritage sites. This shift marks a transition from reactive maintenance to a data-driven, systematic approach, ensuring the long-term survival of one of the world’s most iconic cultural structures.
