DW_Earthworms help recuperate soil and enrich it with much needed minerals. But environmentalists are concerned as earthworms have come under threat from intensive use of manure and acidic soil.
eco-business_2018 is officially the year of climate action in Singapore, and yet the country’s powerful banks are bankrolling huge, greenhouse gas-producing coal-fired power stations in Asia Pacific, a report has found.
DBS is co-financing four 1200 MW coal-fired power plants in Vietnam—Nam Dinh 1, Nghi Son 2, Vinh Tan 4 and Vung Ang 2—and is a financial adviser for a number of planned coal-fired projects in Indonesia including the Jawa-6, Jawa-9 and Jawa-10 plants.

- A new study finds land-use like grazing and managing forests for resource extraction may have released more carbon than previously thought. Its results indicate the world’s terrestrial vegetation is currently sequestering less than half its full carbon-storage potential.
- Of that missing half, the researchers discovered 42 to 47 percent is attributed to land uses that don’t technically change the vegetation cover type. The researchers say that climate change mitigation strategies often focus on reducing intensive land-use like deforestation, with less-intensive uses that don’t change cover type largely overlooked and under-researched.
- One of these less-intensive uses is managing forests for biomass energy production. Many countries are trying to replace fossil fuels with biomass energy in-line with international climate agreements like the Paris Accord.
- The researchers warn that strategies developed under the assumption that producing biomass energy doesn’t come at a carbon cost could harm efforts to fight climate change. They urge that in addition to stopping deforestation, the protection of forest functions, like carbon stocks, should be moved more into focus when it comes to land-use and climate change planning.
As nations try to stem emissions to keep the world from warming more than 2 degrees Celsius in line with their commitments towards the Paris Accord, replacing fossil fuels with renewable alternatives is widely seen as a big step in the right direction. A major source of energy oft-extolled as renewable is biomass from trees, which are usually harvested from managed forests either established on land that has already been deforested or planted where forests didn’t naturally grow. But a new study finds land-use like managing forests for biomass production may come at a much higher carbon cost than previously thought.

The Vietnamese Mekong Delta is one of Earth’s most agriculturally productive regions and is of global importance for its exports of rice, shrimp, and fruit. The 18m inhabitants of this low-lying river delta are also some of the world’s most vulnerable to climate change. Over the last ten years around 1.7m people have migrated out of its vast expanse of fields, rivers and canals while only 700,000 have arrived.
On a global level migration to urban areas remains as high as ever: one person in every 200 moves from rural areas to the city every year. Against this backdrop it is difficult to attribute migration to individual causes, not least because it can be challenging to find people who have left a region in order to ask why they went and because every local context is unique. But the high net rate of migration away from Mekong Delta provinces is more than double the national average, and even higher in its most climate-vulnerable areas. This implies that there is something else – probably climate-related – going on here. Continue reading “Climate change is triggering a migrant crisis in Vietnam”

– Another new year has dawned, and on a world facing serious disruption on many fronts. What are the trends and issues to watch out for in 2018?
One obvious answer is to anticipate how Donald Trump, the most unorthodox of American Presidents, will continue to upset the world order. But more about that later.
Just as importantly as politics, we are now in the midst of several social and environmental trends that have important long-lasting effects. Some are on the verge of reaching a tipping point, where a long-term trend produces critical and sometimes irreversible events. We may see some of that in 2018.

When winter sets in, “polar vortex” becomes one of the most dreaded phrases in the Northern Hemisphere. It’s enough to send shivers even before the first blast of bitter cold arrives.
New research shows that some northern regions have been getting hit with these extreme cold spells more frequently over the past four decades, even as the planet as a whole has warmed. While it may seem counterintuitive, the scientists believe these bitter cold snaps are connected to the warming of the Arctic and the effects that that warming is having on the winds of the stratospheric polar vortex, high above the Earth’s surface.
Here’s what scientists involved in the research think is happening: The evidence is clear that the Arctic has been warming faster than the rest of the planet. That warming is reducing the amount of Arctic sea ice, allowing more heat to escape from the ocean. The scientists think that the ocean energy that is being released is causing a weakening of the polar vortex winds over the Arctic, which normally keep cold air centered over the polar region. That weakening is then allowing cold polar air to slip southward more often.

How to sum up 2017? The global economy improved but there were plenty of unsettling and upsetting events and trends. Catastrophic storms and flooding wrecked homes and livelihoods from South Asia to the Caribbean. Education quality in many countries fell short even as much of the world raced into the digital age. Yet extreme poverty continues to decline. Innovation and technology are enhancing the quality of life. And human capital is now the biggest driver of wealth in the world today. Here’s what 2017 looked like in 12 charts.
1. Millions faced famine and required emergency aid
2. The world emitted historic amounts of carbon
3. Natural disasters dominated the news
4. Two-thirds of global wealth is human capital
5. There’s a crisis in learning
6. Nutrition affects learning, and millions of children remain stunted
7. Child marriage carried high personal and economic costs
8. The world’s population is young. And jobless.
9. Natural capital and biodiversity are undervalued
10. Globally, about half of elections are considered free and fair
11. Starting a business is getting easier
12. The power of renewables

Biến đổi khí hậu và các đập nước ở thượng nguồn đang đe dọa khu vực quan trọng này và vấn đề trở nên khó kiểm soát được. Nhưng có phải những vấn đề lớn nhất của ĐBSCL đều do chính Việt Nam tạo ra?
Đồng bằng sông Cửu Long của Việt Nam, nơi ở của gần 20 triệu người, là một trong những môi trường nông nghiệp có năng suất cao nhất trên thế giới, nhờ vào mạng lưới kênh rạch, đê, cửa cống và rãnh thoát nước phức tạp.
Về thế mạnh nông nghiệp của ĐBSCL, Việt Nam đã đi từ một nhà nhập khẩu gạo lâu năm và trở thành một nước xuất khẩu lớn. Tuy nhiên, nông dân trong khu vực rất quan tâm đến các chính sách an ninh lương thực của chính phủ, trong đó yêu cầu hầu hết đất đai của ĐBSCL phải được dành cho sản xuất lúa gạo. Và nhiều người trong số họ đang có biện pháp để phá vỡ các quy tắc, theo những cách mà không phải lúc nào cũng thân thiện với môi trường.

VietNamNet Bridge – Well-meant but misguided climate change interventions in the Mekong Delta are set to do more harm than good, and only a change in policymakers’ mindset can reverse the damage, an independent researcher and expert said on December 14.

The change in mindset would involve a shift from forceful interventions to embracing natural cycles, said Nguyen Huu Thien.
Thien, whose work focuses on the Mekong Delta’s ecology, was giving his assessment of Resolution No 120 on sustainable development for the Mekong Delta that Prime Minister Nguyen Xuan Phuc signed in November. Continue reading “Only a fundamental mindset shift can save the Mekong Delta: expert”
