In a remarkable display of international collaboration, Tanzania’s Ngorongoro-Lengai Global Geopark has been revitalized with the assistance of Chinese expertise, showcasing the transformative power of green development and advanced technology. This project, spearheaded by engineers from the Tianjin Center of the China Geological Survey, marks a significant milestone in the geopark’s journey from near exclusion from the UNESCO Global Geoparks Network to full recognition of its progress. The geopark, Tanzania’s first and only global geopark, has become a symbol of China’s commitment to sustainable development and the harmonious coexistence of humans and nature. The reconstruction project involved a meticulous geoheritage survey of the Ol Doinyo Lengai volcano, a task that required Chinese and Tanzanian teams to undertake a grueling seven-hour climb to the crater. The survey, conducted under the cover of darkness to capture the molten lava’s golden hue before it turned gray in daylight, provided crucial data for planning sightseeing and scientific expedition routes. This endeavor not only highlights the technical prowess of Chinese engineers but also underscores the potential of international partnerships in promoting environmental conservation and sustainable tourism.
