T

he Environment Ministry is planning to roll out emergency measures to prevent the extinction of the endangered Irrawaddy dolphins (Orcaella brevirostris) in East Kalimantan’s Mahakam river, where only around 66 of the dolphins are estimated to remain in the wild.

“The government will take serious action, as the Mahakam Irrawaddy dolphin population has dropped to an alarming level,” said the ministry’s head of pollution control and environmental degradation Rasio Ridho Sani on Sunday, as quoted by Antaranews.

Ridho added that the Environment Ministry has recently designated Muhuran village and Sabintulung village in Kutai Kartanegara regency, as conservation areas for the Mahakam Irrawaddy dolphin. The two villages have been officially named Mahakam Irrawaddy Dolphin Conservation Villages, following Pela village, which was previously established under the program.

The government is also developing a biodiversity credit mechanism, which would allow businesses to invest in environmental protection and habitat restoration. The initiative aims to fund conservation efforts that support sustainable development while benefiting local communities.

The Irrawaddy dolphin is a freshwater dolphin recognized by its blunt, rounded head, lack of a distinct beak and gray coloring. Found in fragmented populations across Southeast Asian rivers, estuaries and shallow coastal waters, the species is noted for its flexible neck, ability to spout water and occasional cooperative fishing with humans.

Listed as Endangered on the International Union for Conservation of Nature (IUCN) Red List, Irrawaddy dolphin populations have declined by more than 50 percent over the past six decades.
