Environmental activists remain jailed in Cambodia on Human Rights Defenders Day
In honor of Human Rights Defenders Day on Dec. 9, Mongabay looks back at The Clearing, a documentary about young Cambodian activists currently jailed for their environmental and social activism. Filmmakers Andy Ball and Marta Kasztelan produced the video for Mongabay with support from the Pulitzer Center.
The film centers around a group of young environmental activists with the Cambodian civil society group Mother Nature Cambodia. The activists have successfully stopped potentially destructive projects, including a major dam and the export of sand from coastal estuaries. They continue to speak out against development projects, which they say hurt both the environment and local communities.
One such project is in Botum Sakor National Park, once Cambodia’s largest national park. “Eighty percent of the park has been handed to private companies,” Ly Chandaravuth, a Mother Nature Cambodia activist, says in the documentary while flying a drone over a deforested area. “We’re filming a video to urge the government to stop giving land concessions inside the national park to corporations. Thousands of families have been evicted because they need to build an airport and casinos.”
Such outspoken activism has drawn the attention of Cambodia’s authoritarian government. Dozens of activists have been arrested over the years and 11 have been jailed. The documentary follows the plight of Chandaravuth, who was arrested in June 2021 then released on bail, as well as four other activists. All five were awaiting trial for their work.
During this time, the activists won the 2023 Right Livelihood award “[f]or their fearless and engaging activism to preserve Cambodia’s natural environment in the context of a highly restricted democratic space.”
Three of the activists traveled to Stockholm, Sweden, to accept the award with the specter of prison hanging over them upon their return. “We face to be in jail again for up to 15 years if the court finds us guilty. And we’re sure that the court will find us guilty,” Sun Ratha, a Mother Nature Cambodia activist, told Right Livelihood officials in Sweden. Ratha and Chandaravuth had already each served five months in jail for their activism, she said.
In July 2024, 10 Mother Nature Cambodia activists, including Ratha and Chandaravuth, were sentenced to six to eight years in prison for insulting the king and plotting against the government.
A government spokesperson justified the sentencing saying, “How can they describe our leaders as destroyers of the nation? We accept all kinds of constructive criticism but not malicious slander. We must accept the fact that development inevitably has some impacts.”
On Dec. 1, a Cambodian appeals court denied a bail request for five of the activists, UCA News reported. It’s the third time they’ve been denied such a request in the year since they’ve been imprisoned.
