Reviving the 'green lungs' of Thi Nai lagoon

The once-vibrant mangrove forests of Thi Nai lagoon in Gia Lai province lie in ruins after a powerful storm in late 2025. Amidst the barren landscape, local communities and authorities are undertaking the arduous task of regenerating these vital ecosystems, which took decades to establish.

Elder Tran Huu Khanh, 79, a resident of Tuy Phuoc commune, recalls the lush greenery that once thrived in the lagoon. His small boat navigates the choppy waters, revealing uprooted trees and dry branches amidst the murky water. "That place used to be very green, now it's so desolate..." he laments.

For over two decades, Khanh has devoted himself to the mangroves in Diem Van village. The storm, however, uprooted trees and buried others under mud, reducing his protected area from over 3 hectares to a mere 0.8 hectares. He remembers the early days of the mangrove restoration project, when few people were willing to participate due to the difficult work and meager compensation.

“

It was very difficult back then, everyone was reluctant. But I thought if I didn't do it, who would?

Initially, they planted mắm and đước trees, but these were quickly destroyed by barnacles. The bần tree proved more resilient and was subsequently used for wider propagation. Khanh also faced challenges from local residents who damaged the mangroves for firewood and through destructive fishing practices, such as using powerful pumps to harvest shellfish, which disturbed the mud and damaged tree roots.

Khanh's daily routine involves patrolling his assigned area, reminding people to avoid harming the mangroves, and clearing debris from young trees to ensure their healthy growth. Through his persistent efforts and those of the community, green belts are gradually being re-established around Thi Nai lagoon.
