  • Vietnam’s $9.3 billion Can Gio Tourist City was recently approved for construction within the buffer zone of a UNESCO Mangrove Biosphere Reserve in Ho Chi Minh City.
  • Developed by Vingroup, Vietnam’s largest private company, the project will require the reclamation of a huge amount of land along Can Gio’s coast.
  • Environmentalists and activists have petitioned the government to reconsider the project, but Vingroup is a key part of the country’s drive toward industrialization and home-grown world-class companies.

HO CHI MINH CITY, Vietnam — A $9.3 billion residential and tourism development has been approved within the buffer zone of the Can Gio Mangrove Biosphere Reserve here in this city of 13 million, Vietnam’s largest urban area. The project was proposed by the Can Gio Tourism Urban Area Joint Stock Company, a subsidiary of Vinhomes, the real estate arm of Vingroup, the country’s largest private company. The Can Gio Tourist City would span 2,870 hectares (7,100 acres), largely on land that would be filled in along the South China Sea coast using sand.

The Can Gio Mangrove Biosphere Reserve, located in Vietnam’s Ho Chi Minh City, is one of the world’s largest areas of reforested mangroves.BY  ON 21 APRIL 2020Mongabay Series: 

  • A majority of the flora in the area was killed by defoliants sprayed by the U.S. Air Force during the Vietnam War.
  • Today, the replanted forest protects the city from storms, and stores huge amounts of carbon dioxide, though development plans and aquaculture pose threats to Can Gio’s continued health.

HO CHI MINH CITY, Vietnam — As the largest urban area in Vietnam, Ho Chi Minh City is known for its kinetic pace of life, rivers of motorbike traffic, and relentless construction. With an official population of 9 million and a booming economy based on manufacturing, real estate and tourism, there is often little space for nature.

It may come as a surprise, even to many who live in Ho Chi Minh City, that one of the world’s great restored mangroves forests lies within the city’s borders.

The Can Gio Mangrove Biosphere Reserve covers 75,740 hectares (187,160 acres), and encompasses all of Can Gio district, the largest and one of the least populated of Ho Chi Minh City’s 24 districts. Can Gio sits between the central districts and the South China Sea, called the East Sea by Vietnam. Tiếp tục đọc “A vital mangrove forest hidden in Vietnam’s largest city could be at risk” →

10 Big Changes for Forests Over the Last Decade

The last decade was pivotal for the world’s forests. The 2010s saw the rise of unprecedented new commitments — from governments and the private sector alike — to bring deforestation to heel. The UN REDD+ framework, the New York Declaration on Forests and the Sustainable Development Goals set out ambitious targets to conserve and restore millions of hectares of forests.

But as this decade ends and a new one begins, it is also clear the world has fallen short on achieving its forest goals. While the impacts of climate change are being felt around the world, forests — an invaluable climate mitigation tool — are still being lost at high rates. Leaders in key countries are back-tracking on forest protection. Tiếp tục đọc “10 Big Changes for Forests Over the Last Decade” →

Ngày 28/12, ông Võ Văn Chánh dẫn đầu đoàn kiểm tra, thị sát khu rừng đồi 90 xã Phú Lý, huyện Vĩnh Cửu (thuộc diện quản lý của Khu bảo tồn Thiên nhiên văn hoá Đồng Nai). Gần một hecta rừng tự nhiên tại đây có 61 cây đường kính 14-60 cm vừa bị đốn hạ với hơn 12 m3 gỗ.

Cùng lực lượng chức năng mất khá nhiều thời gian xem xét quy mô rừng thiệt hại và số gỗ bị đốn hạ, ông Chánh cho rằng sai phạm đã quá rõ, còn vi phạm đến mức nào thì phải điều tra thêm. Sau khi cùng đoàn kiểm tra ra về, ông Chánh một mình quay lại khu rừng tìm hiểu, xác minh thêm. “Đồng Nai lâu nay bảo vệ và quản lý rừng rất chặt chẽ. Giờ xảy ra việc cây rừng bị đốn là rất đáng tiếc, phải xử lý nghiêm”, ông Chánh nói.

Manage Deforestation Risk in Supply Chains

~ Đào Thu Hằng ~ Bạn nghĩ gì về bài viết này?

The world lost 12 million hectares of tropical forests in 2018, according to Global Forest Watch, and nearly 40 percent of deforestation is commodity-driven. Why is it so hard for companies to stop deforestation? Commodities like palm oil, cocoa, beef and soy may change hands dozens of times from the moment they’re harvested until they end up in candy bars, toothpaste or baby formula, making it nearly impossible to track deforestation in products. Today, it is finally possible for a company or bank of any size to analyze and manage deforestation risk using GFW Pro.

Solar farm is good for biodiversity

Ground-mounted PV systems promote biodiversity according to a new study published in Germany. Scientists collected data from 75 MW of solar plants nationwide and found the areas they were located in showed greater diversity and more intact habitat structures and found panels provide a refuge for animals.

 

Rare plant and animal species settle below or next to ground-mounted solar plants.

The issue of vast fields of solar panels restricting other types of land use is still a controversial one for the PV industry but, as the head of Germany’s Federal Association of New Energy Industry Robert Busch said: “Germany is not a plains country but for the climate and energy targets the federal government needs a lot more renewable energy, unless it is … all just lip service.” Tiếp tục đọc “Solar farm is good for biodiversity” →

HÀ NỘI — Villages across the country have benefited from the country’s economic development, however, many do not have measures in place to deal with environmental protection.

The village of Trát Cầu in Hà Nội, which produces blankets, bed sheets and pillows, is a typical example.

Nguyễn Quang Thà, chairman of the Trát Cầu Traditional Villages Association, told Tiền Phong (Vanguard) newspaper that over the past 20 years, more and more foreign enterprises have invested in the village.

Now about 30 enterprises from Japan and South Korea are working there.

“The Trát Cầu Village is like a big workshop which runs all day, every day,” said Thà. Tiếp tục đọc “Villages get rich but suffer environmental consequences” →

What’s causing deforestation? New study reveals global drivers

~ Đào Thu Hằng ~ Bạn nghĩ gì về bài viết này?

MONGABAY

    • Recent advances in satellite-based forest monitoring technology have helped conservationists locate where deforestation may be happening. However, limitations in knowing the causes behind canopy loss have hindered efforts to stop it.
    • A new study released this week provides a step forward toward this goal, identifying the major drivers of tree cover loss around the world.
    • Overall, it finds 27 percent of all forest loss — 50,000 square kilometers per year — is caused by permanent commodity-driven deforestation. In other words, an area of forest a quarter of the size of India was felled to grow commodity crops over 15 years. The next-biggest driver of forest loss worldwide is forestry at 26 percent; wildfire and shifting agriculture amounting to 23 percent and 24 percent, respectively. The study finds less than 1 percent of global forest loss was attributable to urbanization.
    • The study’s authors found commodity-driven deforestation remained constant throughout their 15-year study period, which they say indicates corporate zero-deforestation agreements may not be working in many places. They hope their findings will help increase accountability and transparency in global supply chains.

A new study shows that, in addition to the diversity of tree species, the variety of animal and fungus species also has a decisive influence on the performance of forests. Forest performance comprises many facets besides timber production, such as carbon storage and climate regulation. The study is based on ten years of research in species-rich subtropical forests. A team of researchers led by the German Centre for Integrative Biodiversity Research (iDiv) and the Martin-Luther-University Halle-Wittenberg has published the results in the new issue of Nature Communications. They illustrate that biodiversity must be viewed as a whole in order to maintain the performance of forests.

Southeast Asia is in the grip of a biodiversity crisis

~ Đào Thu Hằng ~ Bạn nghĩ gì về bài viết này?

theconversation.com

Rich in wildlife, Southeast Asia includes at least six of the world’s 25 “biodiversity hotspots” – the areas of the world that contain an exceptional concentration of species, and are exceptionally endangered. The region contains 20% of the planet’s vertebrate and plant species and the world’s third-largest tropical forest.

In addition to this existing biodiversity, the region has an extraordinary rate of species discovery, with more than 2,216 new species describedbetween 1997 and 2014 alone.

Global comparisons are difficult but it seems the Mekong region has a higher rate of species discovery than other parts of the tropics, with hundreds of new species described annually.

Habitat loss

Southeast Asia’s biodiversity is under serious threat; some parts of the region are projected to lose up to 98% of their remaining forests in the next nine years. It’s also thought to be the world’s most threatened region for mammals. Tiếp tục đọc “Southeast Asia is in the grip of a biodiversity crisis” →

The shift could change which prey animals hunt or make it harder to find food

Humans dominate the animal world. Whether hunting or competing for limited space and resources, we are the planet’s superpredator. Other animals seem to understand this, avoiding people if they can help it. But as the human population expands, it is getting harder for other creatures to find somewhere to hide during the day. Now new findings indicate mammals around the world have come up with another strategy: They are becoming nocturnal. Exactly what this bizarre shift means for the future of individual species—and entire ecosystems—is unknown. Tiếp tục đọc “Humans Are Driving Other Mammals to Become More Nocturnal” →

Cambodia’s forests are being felled at a shocking rate, as poachers and corrupt officials profit from the black market trade in rare wood species, which is being exported to Vietnam — and beyond.

The Aoral Wildlife Sanctuary in Kampong Speu province is just a three-hour drive from Cambodia’s capital, Phnom Penh. But the scenery here couldn’t be more different than in the sprawling metropolis — even a military outpost in the reserve is peaceful and picturesque. A traditional stilt house has hammocks, chickens and ice-cold beer. Outside, a few soldiers are playing pétanque as a black pig snuffles the earth.

But behind this idyllic scene in the Cardamom Mountains, a billion-dollar black market is thriving. Tiếp tục đọc “Corruption fueling deforestation in Cambodia: poachers and corrupt officials profit from the black market trade, being exported to Vietnam — and beyond.” →
