Plastic bags and bottles, aquaculture feed bags, nylon netting and ropes don’t sound like the makings of a healthy fishing haul. However, nets replete with these items are a near-daily reality for the majority of fishers interviewed by researchers during a recent study in Vietnam. Plastic waste causes small-scale fishers in Vietnam to lose an average of $3,421 per vessel, per year, in lost fishing time, reduced catch efficiency and damaged gear, the study assessing the economic impacts of plastic debris on fishing livelihoods found. This represents a 10-25% reduction in the annual income of vessel owners. Fishers interviewed for the study reported that they had significantly increased their fishing efforts in recent years in response to the combined pressures of overexploited fish stocks and plastic pollution. “Before, 6-7 hauls were enough [to turn a profit],” one interviewee told the researchers. “Now it takes 20-25 hauls.” The study also highlights how fishers could play a significant role in solutions tackling the plastic pollution crisis, including through “fishing for litter” programs that pay fishers modest financial incentives to bring back plastic bycatch for disposal and processing on land. “When you see firsthand the sheer volume of [plastic waste] in Southeast Asia, and how it directly impacts people’s lives and livelihoods, it crystallizes very clearly why we need to address this,” study co-author Michel Kaiser, a professor of fisheries conservation at Heriot-Watt University in the U.K., told Mongabay in an interview. “Fundamentally, turning off the source of the plastic is key, but…This article was originally published on Mongabay

Conservationists say connecting existing protected areas through biodiversity corridors is vital in many landscapes to prevent further loss of species and habitats. Yet the households living inside conservation areas often face stark financial tradeoffs associated with lost access to resources, sometimes making new designations controversial. A recent study from the rugged mountains of central Vietnam, however, suggests that biodiversity corridors can bring significant economic benefits to the households who live inside them. The study, published in Conservation Science and Practice, analyzed interviews with 120 families living in four villages in Quang Nam and Thua Thien provinces within the Annamite mountain range to find out how financial incentives tied to two biodiversity corridors connecting isolated protected areas affected people’s lives and livelihoods. Households inside biodiversity corridors earned substantially more, mainly from conservation-linked payments, than those outside them. However, they also made less money from forest resources due to greater restrictions on how they could use their land. The researchers say their findings underscore how conservation-linked payments and other longer-term benefits from living near flourishing forests, such as water purification, healthy pollinator populations and conservation-based jobs, can help communities recoup income they once derived from forest exploitation. “By providing regular financial benefits from forest protection, programs like PFES [Payment for Forest Ecosystem Services] create incentives for communities to maintain forest cover and reduce pressures on critical habitats,” study lead author Nguyen Van Tri Tin, a conservation scientist at Southern Cross University in Australia at the time of the study, told Mongabay in…This article was originally published on Mongabay

Forest canopies create the conditions for an extraordinary diversity of life to thrive. By casting shade and retaining moisture in the air and soil, they generate cool and stable understory environments. In the tropics, this regulating effect is particularly crucial for countless species that otherwise would be unable to survive in the extreme heat of surrounding open landscapes. However, forest scientists are increasingly concerned that the combined pressures of global warming and habitat degradation could undermine forests’ critical thermal buffering capacity. New research from Southeast Asia predicts forests across the region will experience unprecedented peak temperatures over the next three decades. Heat levels beneath the canopy could hit new highs even within currently intact ecosystems by 2050, the study found, potentially exposing forest-dwelling animals, plants and fungi to severe levels of heat stress. “Our findings show that climate change is not only warming the atmosphere globally, but also reshaping the local conditions that species experience inside forests,” said Erone Ghizoni Santos, who led the study while he was a Ph.D. student at the University of Helsinki in Finland.

Region-wide warming Prior research in Malaysian Borneo has demonstrated that when forests are degraded, such as through logging, they become more affected by climate shifts in the surrounding landscape. Depleted canopies allow more sunlight to reach the ground and trap less moisture, allowing heat to permeate the ecosystem. What was missing,…This article was originally published on Mongabay

In a forest reserve in northeastern Bangladesh, two Chinese pangolins rescued from trafficking have been given a second chance at life in the wild. As poaching pushes the critically endangered species toward extinction, the releases aim to do more than boost flagging local populations. With the help of tiny radio transmitters, scientists are tracking each individual to learn about their survival, movements and behavior. Equipped with an armor-plated body, elongated snout and sticky tongue the length of their body, Chinese pangolins (Manis pentadactyla) are beautifully adapted to a life spent grubbing out ant and termite nests and resting in burrows dug into the forest floor. However, like all eight of the world’s known pangolin species, Chinese pangolins are among the most trafficked mammals on Earth. They’re plucked from forests across their range to feed an illegal trade driven by demand in China and Vietnam for pangolin meat, and scales and other body parts used in traditional medicines. While no global population counts exist, the IUCN, the global wildlife conservation authority, classifies the species as critically endangered, due to the combined threats of poaching, habitat loss and deforestation. High poaching rates in China in the late 20th century caused local extinctions, displacing hunting pressure to other parts of the species’ range, which spans from northern India and Nepal, through Bangladesh and northern parts of Southeast Asia to southern China and Taiwan. Yet very little is known about the species in many countries, including Bangladesh, says Shahriar Caesar Rahman, co-founder and CEO…This article was originally published on Mongabay

KRABI, Thailand — Beneath a humid canopy of rubber trees, Sathit Phromraksa pauses to inspect a coagulated ball of rubber in a palm-sized bowl fastened to a trunk. Last night, he and his wife worked their way through the plantation, carefully carving a line in the bark of each tree to stimulate the flow of milky latex. With a total 500 trees to tap in their 1.6-hectare (4-acre) plantation, their work took them from midnight to 3:30 a.m. “I inherited this rubber farm from my father,” says 59-year-old Sathit, a lifelong resident of Namgaan subdistrict in Thailand’s Krabi province. “Back then, my family used a lot of chemicals to control weeds and pests, but now, we follow organic practices.” Sathit is one of roughly 1.7 million smallholders who produce 90% of Thailand’s natural rubber supply across millions of individual plantations, most of them no bigger than his. For many, staying profitable is a constant challenge amid fluctuating market prices, crop diseases and climate change. Now, the EU Deforestation Regulation (EUDR) is poised to add to the pressures facing small-scale producers like Sathit. Under the law, set to take effect in January 2027, only suppliers who can prove their land wasn’t cleared after Dec. 31, 2020, will be allowed to continue selling rubber to EU markets. As the world’s leading natural rubber producer, the economic implications for Thailand are significant. While the bulk of its exports go to China and Malaysia, the value of Thai rubber entering the EU increased by…This article was originally published on Mongabay
