From Polluted to Tourist Paradise

Dianchi Lake, the largest freshwater lake in Yunnan province, has undergone a remarkable transformation. Once heavily polluted, the lake has seen a resurgence in tourism thanks to local government efforts to protect the environment and restore the ecosystem.

During the early years of industrialization and urbanization, Dianchi Lake became one of the most polluted lakes in China. Its water quality plummeted to Grade V, the lowest level in the national five-tier grading system for surface water.

However, persistent efforts have led to significant improvements. Through comprehensive and systematic clean-up measures, as well as efforts to control pollution sources, the lake's water quality has been maintained at Grade IV for six consecutive years.

The positive impact extends beyond the water quality. Vegetation in the wetlands around the lake has increased dramatically, from 13.1 percent in 2007 to the current 81 percent. The number of plant species has also increased, from 232 to 303, and the number of bird species has risen from 89 to 175.

This ecological restoration has attracted tourists, with the Kunming Dianchi National Tourism Resort receiving 23.68 million visits last year. Tourism revenues reached 26.2 billion yuan ($3.69 billion), an increase of 45.58 percent year-on-year.

The resort is further enhancing the visitor experience by building a 137-kilometer greenway around the lake. This will allow visitors to walk or cycle while enjoying the beautiful scenery and exploring the unique charm of dozens of lakeside villages.

The development emphasis around Dianchi Lake has shifted from real estate and commercial industries to eco-friendly industries such as tourism, culture, sports, wellness, and health. This shift is evident in the development of 46 villages around the lake, each showcasing its own unique historical and cultural characteristics.

One such village is Haiyan, a 600-year-old fishing village that has become an internet-famous destination for its stunning sunsets. The village is now home to over 100 businesses, including restaurants, homestays, coffee shops, and art studios, creating over 300 jobs and generating significant income for local residents.

Dianchi Lake's transformation from a polluted body of water to a thriving tourist destination is a testament to the power of environmental restoration and sustainable development. The lake's story offers hope for other polluted areas around the world, demonstrating that even the most degraded ecosystems can be revitalized with dedicated efforts.
