Global Forest Watch’s (GFW) deforestation alerts provide information about loss of tree cover in near-real-time, making them a critical tool for those working to combat deforestation. Existing alerts on GFW have been used to help Indigenous and local communities protect their forests, halt and prosecute environmental crimes and protect threatened wildlife.
However, in the past, alerts only let users know there’s been a disturbance without identifying a cause, other than a few limited classes such as fires.
Now, new drivers of deforestation alerts data is available on GFW that shows the causes of alerts across the tropics. This innovative data set uses an AI method to assign drivers to GFW’s integrated deforestation alerts in the three major forested regions in the tropics, allowing users to see what’s driving loss in near-real-time in these regions for the first time.
Critically, this information helps users distinguish between tree cover loss from natural and human causes, enabling more targeted action from those managing forests and reducing the need for costly field visits. Further, the data also provides more rapid information to estimate ecological impacts and supports better understanding of carbon emissions related to forest disturbances.
Thị trường tài sản mã hóa mang đến cơ hội, nhưng cũng đầy rẫy cạm bẫy. Trong bối cảnh các thủ đoạn lừa đảo ngày càng tinh vi, các nhà đầu tư cần học cách nhận diện, phòng tránh các mô hình lừa đảo để tự bảo vệ mình.
Trong những năm gần đây, thị trường tài sản mã hóa (crypto) đã bùng nổ tại Việt Nam, thu hút một lượng lớn nhà đầu tư, đặc biệt là giới trẻ. Với tiềm năng lợi nhuận cao và tốc độ tăng trưởng ấn tượng của các đồng tiền như Bitcoin, Ethereum, hay các mô hình tài chính phi tập trung (DeFi), không ít người đã kỳ vọng đây sẽ là cơ hội đổi đời.
Cạm bẫy lừa đảo ngày càng tinh vi trên thị trường tài sản mã hóa.
Theo số liệu từ Triple-A, năm 2024 có hơn 17 triệu người Việt Nam đang sở hữu tài sản mã hóa, chiếm gần 17% dân số. Tuy nhiên, sự phát triển nhanh chóng này cũng đi kèm một lỗ hổng lớn: phần lớn nhà đầu tư là người mới, tiếp cận thị trường thông qua mạng xã hội hoặc lời rỉ tai, không có nền tảng về công nghệ blockchain, pháp lý tài sản số hay các phương thức lừa đảo phổ biến hiện nay.
Mới đây, thông tin về “Madam Ngo” bị Interpol truy nã vì tội lừa đảo đầu tư tiền điện tử và ngoại hối, lừa đảo hơn 2.000 nạn nhân người Việt Nam số tiền khoảng 300 triệu USD đã gióng lên hồi chuông cảnh báo về những rủi ro tiềm ẩn trong thị trường này.
Cambodia’s central bank has reportedly revoked the banking license of a conglomerate accused of illicit online activities. But doubts abound about Phnom Penh’s commitment to taking action against cyberfraud networks.

The banking arm of a Cambodia-based conglomerate accused of running the world’s “largest ever illicit online marketplace” has had its banking license revoked by the Cambodia’s central bank, Radio Free Asia reported last week.
Huione Guarantee, the Telegram marketplace of Huione Group, has reportedly processed up to €22 billion ($24 billion) in illicit transactions since 2021, making it by far the world’s largest illegal online marketplace, cryptocurrency compliance firm Elliptic reported last year.
Huione Pay, the group’s banking arm, had its license withdrawn because of noncompliance with “existing regulations and recommendations that may have been made by the regulators,” a National Bank of Cambodia spokesperson told Radio Free Asia, a US Congress-funded media outlet.

Long-term intensive chemical use in Laos’ banana farms has degraded the country’s once-fertile soil, and it may take nearly half a century to restore it.
Laos’ fertile soil and its proximity to China have created ideal conditions for banana cultivation to meet the surging demand from Chinese consumers.
This fruit frenzy has attracted Chinese companies to seek farmland in Laos, a landlocked country that has embraced a “green agriculture” approach to combat poverty.
With government approval, the sector has expanded, offering jobs, infrastructure development, and revenue from land once considered undervalued.
However, an investigation by Mekong Eye and the Rainforest Investigations Network (RIN) reveals that the fruit plantation boom has left a legacy of soil degradation and uncertain livelihoods for many local farmers.
OUDOMXAY & BOKEO, LAOS – Northern Laos is experiencing soil degradation after years of monocropping and widespread chemical use on banana farms operated by Chinese entrepreneurs.
Thiep doesn’t remember the name of the Chinese fruit company that leased his family’s land, only that it was one of the first to arrive in his northern Lao village in 2007.
After a decade of monocropping bananas, the company left and then returned the land to his family. But in the interim, the earth had changed in ways Thiep and his household couldn’t have anticipated.
“The soil is unusually hard and dry, not like it used to be. We had to replace the plow with a stronger one just to break the ground,” Thiep recalled.
His family members invested extra effort into its first rice crop after reclaiming the plotland. That year, they enjoyed a bumper harvest that was more than they had before the arrival of the Chinese company. But it was the last time they saw such abundance.
“The yield kept decreasing after that,” Thiep said, planting seedlings in the flooded paddy. “Before we leased it out, this plot produced 60 bags of rice. Now it’s down to 30, not enough for the family to eat.”
Nearly two decades ago, Chinese entrepreneurs, attracted by geographic proximity, blanketed northern Laos with banana plantations.
Exporting bananas to China quickly became an economic mainstay, replacing the long reliance on subsistence rice farming. The plantations not only created local jobs but also increased income for households leasing their land to companies.
But investment capital is bittersweet: it may have provided the region with a ladder out of the depths of poverty, but it has ushered in new perils.
Some local workers have reportedly fallen ill or died after pesticide spraying on farms.
Young Hmong workers rest after long hours of labor on a banana plantation in Oudomxay province, northern Laos. Many, including children under 15, face direct exposure to hazardous agricultural chemicals used in the plantations.
A 2017 study, conducted with the Lao government’s involvement, found that agricultural chemicals – used intensively and without consistent management on banana plantations – had poisoned rivers and soil, and harmed the health of residents and plantation workers.
Among the chemicals identified were paraquat – a highly toxic herbicide banned in several countries, including Laos and China – and chlorothalonil, a hazardous substance banned in the EU in 2020 due to its potential to pollute groundwater and cause cancer.
Facing the issue, an official from the Ministry of Industry and Commerce verbally stated in early 2017 that the Prime Minister’s Office had ordered a ban on all commercial banana cultivation, according to the Laos News Agency. However, our reporter was unable to find any official orders on public platforms dating back to 2016.

NHA TRANG, Vietnam (AP) — The gentle waves off the coast of central Vietnam’s Nha Trang obscure an open secret: The life-giving coral reefs below are dying. The waters are eerily devoid of fish. The bounty of the ocean is coming to an end.
This is why Binh Van — who fished in these waters for over two decades — now charters his boat to Vietnamese tourists wanting to experience the thrill of fishing in the deep waters of the South China Sea. But there is only squid, which is flourishing in oceans warmed by climate change, to catch. His passengers don’t mind as the boat moves away from Nha Trang’s twinkling beach resorts. But Van is pensive.

It wasn’t always like this. There was a time when he’d catch 70 kilograms (154 pounds) of fish, like tuna and grouper, in one night. He can’t make money on the squid.
A deep dive into the rationale behind some of Asia’s reclamation projects, the toll they take on our environment and communities, and the search for more sustainable alternatives.
Reclamation is seen as a solution for countries to deal with increasing land demands, by expanding their territory and rehabilitating previously uninhabitable lands or seas. Yet, the process guzzles an alarming amount of sand, causing massive environmental damage as well as a rise of transnational criminal syndicates trading in illegal sand.
Coastlines, ecosystems, and entire populations are now facing adverse impacts due to increased sand-mining activity, with one of the major driving forces being land reclamation. This practice of creating new land at sea is often touted as a solution to urban expansion and climate change.

Fifty years ago Thinh Nguyen left his homeland aboard an American navy ship. Some of his compatriots escaped in helicopters. Tens of thousands fled in makeshift boats. Many more, including Mr Nguyen’s father and brother, were left behind as troops from North Vietnam stormed into Saigon, then the capital of American-backed South Vietnam. The chaotic evacuation marked the end of the Vietnam war, badly damaged American credibility and left Vietnam in Communist hands. It also helped create one of the world’s biggest diasporas.
The intricate histories and niche experiences that we love about Saigon can make it difficult to explore. If you enjoy reading about Saigoneer’s favorite destinations, Urbanist Travel can help create a tailor-made itinerary based on your requests. More Informatio
Read this article in Vietnamese at Sài·gòn·eer.From the very first discussions in 1868 regarding a new marketplace for Saigon, it was not until 1914, that Bến Thành Market became a reality. The birth of the market was like a dream come true, one that came together after nearly five decades of debate in search of solutions for the city’s infrastructure woes.
The five-decade quest to seek a “worthy” marketplace
In her research conducted on the vendors of Bến Thành, anthropologist Ann Marie Leshkowich recounts the lengthy discussions of then Saigon’s colonial administration regarding the establishment of a new commercial center, one that, according to them, must become a place “worthy” of the metropolis they were helping to create.
In 1868, the French had only spent about one decade trying to install a colonial network in Vietnam. Members of the Municipal Council (Conseil Municipal) had the thought of building a new marketplace from metal, replacing traditional thatch markets. In 1869, a budget of 110.000 francs was greenlit, but by 1870, the estimated expenditure had ballooned threefold, causing them to reconsider the planned building methods and amount of materials.

China recently approved the construction of the world’s largest hydropower dam, across the Yarlung Tsangpo river in Tibet. When fully up and running, it will be the world’s largest power plant – by some distance.
Yet many are worried the dam will displace local people and cause huge environmental disruption. This is particularly the case in the downstream nations of India and Bangladesh, where that same river is known as the Brahmaputra.
The proposed dam highlights some of the geopolitical issues raised by rivers that cross international borders. Who owns the river itself, and who has the right to use its water? Do countries have obligations not to pollute shared rivers, or to keep their shipping lanes open? And when a drop of rain falls on a mountain, do farmers in a different country thousands of miles downstream have a claim to use it? Ultimately, we still don’t know enough about these questions of river rights and ownership to settle disputes easily.
The Yarlung Tsangpo begins on the Tibetan Plateau, in a region sometimes referred to as the world’s third pole as its glaciers contain the largest stores of ice outside of the Arctic and Antarctica. A series of huge rivers tumble down from the plateau and spread across south and south-east Asia. Well over a billion people depend on them, from Pakistan to Vietnam.
Tại khu vực thượng nguồn sông Cu Đê (Đà Nẵng), một đoạn sông Bắc đang bị những kẻ trộm cát cày xới, xâm hại đến cảnh quan và môi trường tự nhiên.

Xe múc, phương tiện âm thầm đào trộm cát
Xã Hòa Bắc (huyện Hòa Vang) đang được xây dựng thành điểm du lịch sinh thái ở Đà Nẵng với nhiều con suối trong lành. Vào mùa hè, dòng sông Cu Đê và những con suối nằm ở thượng nguồn như sông Bắc thu hút đông đảo người dân và du khách đến vui chơi, nghỉ mát.
Tuy nhiên, một đoạn sông Bắc đang bị “cày xới” bởi các đối tượng khai thác cát lậu.

Theo ghi nhận của Tuổi Trẻ Online, tình trạng khai thác cát trái phép ở khu vực này đã diễn ra được một thời gian.
Trước đó vào tháng 8-2024, phóng viên ghi nhận nhiều người đã đưa máy móc, xe tải tiến về khu vực sông Bắc (phía trên vũng Bọt) để múc trộm cát.
Các hoạt động khai thác cát trái phép này thường diễn ra vào ban đêm hoặc rạng sáng để tránh bị lực lượng chức năng phát hiện.
Theo ghi nhận, khoảng 22h, một người lái xe tải chở theo máy xúc tiếp cận đến điểm khai thác. Người này nhanh chóng xúc cát đổ đầy thùng xe tải dưới ánh sáng lờ mờ của chiếc đèn pin.

Trước khi chở cát rời đi, người này gom cát lại thành đống để thuận tiện cho việc khai thác lần tiếp theo.
Sau một thời gian, các hoạt động khai thác tạm ngưng khi nước suối dâng cao vào mùa mưa cuối năm 2024. Tuy nhiên, thời gian gần đây, việc khai thác cát trộm tái diễn ở khu vực này. Các đối tượng tiếp tục tuồn đi nhiều m3 cát, sỏi dọc bờ suối.
Hậu quả để lại là một đoạn bờ suối bị cày xới, biến dạng, nguy cơ làm thay đổi dòng chảy và tiềm ẩn nhiều nguy cơ sạt lở vào mùa mưa.
Vietnam and China, the two largest markets for traditional medicine (TM) that uses wild plants and animals, announced a new partnership in January to adopt practices that protect wildlife while preserving the countries’ cultural heritage.
The first-of-its-kind agreement involved leading TM associations from Vietnam and China — the Vietnam Oriental Traditional Medicine Association (VOTMA) and the China Association of Traditional Chinese Medicine (CATCM) — along with researchers, policymakers and pharmaceutical leaders. TRAFFIC, an international NGO monitoring illegal wildlife trade, facilitated it.
The partnership aims to explore “several sustainable practices to make traditional medicine more conservation-friendly,” said TRAFFIC Vietnam director Trinh Nguyen in a statement to Mongabay. She said these include encouraging practitioners to switch to legal, sustainable and cultivated plant-based alternatives, and eliminating illegal wildlife ingredients in prescriptions.
Historical TM practices in the two countries have incorporated wildlife-derived ingredients, including those from threatened species, such as tiger bones, pangolin scales, rhino horns and bear bile. While many such ingredients are legal to trade inside China, the wildlife parts are often sourced from other countries to meet domestic demand. Many of the threatened species are, however, listed on CITES Appendix I, making the international trade in their parts illegal. As TM becomes popular globally, conservationists worry about its impact on wildlife.
Plastic is now ubiquitous in the Mekong, Asia’s Mother of Rivers, and experts and local people are struggling to contain the risks to human health, biodiversity and livelihoods

On Sơn Island in Viet Nam’s Mekong Delta, Le Trung Tin scatters fish feed into his ponds, where dozens of snakehead fish leap through the surface in synchronized bursts. “I taught them how to do that,” he says proudly, tossing another handful of feed at his fish.
The scene looks idyllic, but Le’s fish farm is a reluctant response to an escalating crisis. For decades, he made his living fishing the Hậu River, a distributary of the Mekong. But in recent years, plastic waste clogged his nets and strangled the fish. “I had no choice but to stop,” he says. “Everything was tangled – trash, nets, even the fish themselves. It was hopeless.”
Now, Le relies on enclosed ponds using filtered water to keep his fish alive. “I built this ecological environment free of plastic waste, chemical spills and [protected it from] extreme weather,” he says.
Le’s experience reflects the wider challenges facing the Mekong. Stretching over 4,300 kilometres from the Tibetan Plateau to the South China Sea, the river supports nearly 70 million people and some of the world’s most biodiverse ecosystems. Yet, it is one of the most plastic-polluted rivers in the world and among the 10 rivers in Asia that carry the vast majority of plastic to the sea. The Mekong dumps – by some estimates – tens of thousands of tonnes each year into the ocean, with plastic waste accumulating along its banks, tributaries and lakes.
Plastic enters the Mekong in myriad ways – agricultural runoff, unregulated dumping and a flood of single-use packaging from upstream countries like China and Myanmar. It accumulates in hotspots like Tonle Sap Lake in Cambodia and the wetlands of Vietnam’s Mekong Delta, where this plastic waste threatens biodiversity, food security and human health.
