PHNOM PENH — In Cambodia’s Koh Sdach archipelago, where turquoise waters hide mounting environmental pressures from overfishing and plastic waste to climate change, one local leader has turned grassroots action into a model for marine conservation. Koh Sdach commune deputy chief Sorn Srenh, a marine advocate who studied fishery science at the Royal University of Agriculture in Phnom Penh, stands at the intersection of science, policy, and community advocacy. For years, the 38-year-old has worked relentlessly with the fishing community to protect their livelihoods while pushing for sustainable practices that safeguard marine biodiversity. His efforts, ranging from organizing community capacity to lobbying for stronger local enforcement of fishing regulations, have made him a trusted voice among villagers and a rare example of commune-level leadership driving tangible environmental change. For years, Srenh has also been working with the Cambodian government’s Fisheries Administration and the UK-based NGO Fauna & Flora to help establish Koh Sdach’s community fisheries management area, known as a Marine Fisheries Management Area (MFMA). In a phone interview with Mongabay, Srenh shared his vision for community-led conservation, the challenges of balancing economic survival with ecological stewardship, and why protecting Cambodia’s seas matters far beyond its shores.

SEOUL — At 2 a.m. one night, two Indonesian fishers were gripping a flimsy, makeshift rope, hanging on for dear life. The precarious rope dangled from the eighth-floor window of a motel room overlooking a dark alley in the South Korean port city of Busan, swinging left and right with the wind. The men had been locked up in that room for nearly 24 hours, and they were trying to make their escape. But the crude rope, made out of tied bed sheets, unraveled, sending the men plunging. One fell to his death, hitting the pavement headfirst. The other survived with a broken leg, according to Lee Han-sook, director of the Migration and Human Rights Institute, a Busan-based civic group. She was briefed on the July 21 incident by the survivor, whom she declined to name. According to activists, the incident served as one of the last straws that prompted the government to boost efforts to crack down on human trafficking, especially abuses against migrant workers in the country’s $7.5 billion fishing industry. On Sept. 2, the Ministry of Gender Equality and Family and the Ministry of Oceans and Fisheries announced they had amended national guidelines on human trafficking to make it easier for law enforcement officials to spot and stop forced labor and other abuses in the fishing industry. The new guidelines outline specific situations in which the likelihood of human rights abuse is high, such as seeing workers who have physical injuries being left untreated, workers who have…This article was originally published on Mongabay

HONG KONG — “Spiderman … Tom Holland,” two secondary school boys repeated to each other as they watched conservationist Harry Wong nimbly climb a tall tree at their school, St. Louis School, in downtown Hong Kong. On a humid September afternoon, Wong installed a nest box for yellow-crested cockatoos (Cacatua sulphurea) on a candlenut tree (Aleurites moluccanus). Equipped with a harness and ropes, he climbed up the tree, installed the box, and quickly rappelled down. Wong and Astrid Andersson, a biologist and postdoctoral researcher at the University of Hong Kong (HKU), are the dynamic duo behind HK Cockatoo Watch, a conservation project that seeks to protect the city’s feral yellow-crested cockatoos.

Yellow-crested cockatoos are considered to be critically endangered, with fewer than 2,000 individuals remaining in their native range in eastern Indonesia and Timor-Leste. However, few people know that Hong Kong is home to the largest wild population of the species outside the two Southeast Asian countries. There are roughly 200 cockatoos in the city, or about 10% of the global wild population, believed to be descendants of released or escaped pets. The number is stable, thanks to the lack of natural predators and strict legal protection. A recent DNA analysis study by Andersson and her research team found that Hong Kong’s feral cockatoos have unexpectedly high genetic diversity and…This article was originally published on Mongabay

HONG KONG — On a mid-September day, Wong Ping-kuong, 74, and his colleagues worked quickly to spray clean an outdoor staircase and elevator landing. It was only mid-morning, but already hot. The temperature later rose to 31°Celsius (87.8°Fahrenheit). Wong has felt the impact of climate change in the half-century that he has worked as a construction worker and later an outdoor cleaner. “It’s gotten hotter. Before, I didn’t sweat; now my back is often covered with sweat,” he told Mongabay. Wong and his colleagues consider themselves lucky. They say when temperatures are high, they can go inside their truck, turn on the AC, and cool down a little. However, heatstroke can occur quickly, setting in within 10-15 minutes. Outdoor workers like Wong are exposed to increasing risks of heat-stress-related health problems, such as dizziness, headache, nausea, heatstroke, or acutely worsening pre-existing chronic conditions such as cardiovascular and respiratory diseases. Like many places around the world, Hong Kong is suffering from extreme temperatures. Official figures show it is warming by nearly half a degree Celsius per decade. The city also experiences longer and hotter summer months, with the number of “very hot days” quadrupling since the 2000s, data from the Hong Kong Observatory (HKO) shows. On Aug. 9, HKO logged 36.9°C (98.4°F), the highest temperature at its main monitoring station since record-keeping began in 1884. In the outskirts of Hong Kong, the weather service measured even higher temperatures that day: 39.8°C (103.6°F) — another record. Unlike other developed economies, Hong Kong…This article was originally published on Mongabay

CANBERRA — Australia has a problem with the very creature that is its official national symbol: The kangaroo. Endemic to Australia, they live across the country, from north to south, and from east to west. Australia has four main kangaroo species: The red kangaroo (Osphranter rufus), the largest of all species, mainly found in the outback through the Northern Territory; the western grey kangaroo (Macropus fuliginosus), in the southeastern part; the eastern grey kangaroo (Macropus giganteus), in most eastern states, including Tasmania; and antilopine kangaroo (Osphranter antilopinus), in the northern part. Population surveys by the Department of Climate Change, Energy, Environment and Water estimate there are between 30 million and 50 million kangaroos in Australia. Their number fluctuates from year to year depending on drought periods, and it even exceeds the country’s 27.8 million human population. The abundance of the macropods across the country creates a conservation dilemma. They have been blamed for overgrazing and causing environmental damage such as soil degradation and biodiversity decline. Many Australian states have resorted to kangaroo culling. A recent culling in the Australian Capital Territory (ACT), which includes the federal capital Canberra, encapsulates the controversy about the policy. The Australian Capital Territory, home to an estimated 122,000 eastern grey kangaroos, has one of the highest recorded densities in Australia. Image by Shane Lin via Flickr (CC BY-NC 2.0).
