Here are all the posts about the water and air quality, the recycling and other miscellaneous topics that are not in Sustainable development or Energy
I was previously noting that the Sahara desert is slowly turning green. To a new study hurrying the process and extending it to the Australian outback by planting eucalyptus trees (left) could absorb our global CO2 emissions. Indeed this geoengineering idea would absorb eight billion tons of carbon a year. But we shouldn’t forget that […]

To the pictures taken by satellites the annual rate of deforestation in the Amazon rainforest have dropped by no less than 46 percent this year. If these figures were confirmed by ground data this would prove significant. These figures are the lowest since record keeping begun 21 years ago and can be explained by the

The Indian government announced it on last week and the news spread around the world as to their analyses the country’s greenhouse gases emissions are due to at least triple by the next twenty years. One might think this is huge, but not that much as the country’s emissions are accounting for five percent of
Indian greenhouse gases emissions to triple Read More »
This week no less than three news about the arctic hit my aggregator. First and foremost the WWF released a new report on how the melting of the pole could threaten no less than a quarter of the human population. The second one is about Mr. Ban Ki-moon – the UN secretary general – who

India is known for planting thousands of trees in single days but it seems that Pakistan is also working on massive afforestation projects as it planted no less than 541,176 trees in 24 hours. Meanwhile, Bangladesh is ready to invest billions in environmental protection and received $19 million from Germany and the United States for

We have seen it before, biodiversity is impressively rich in places where Mankind isn’t too much present. Indeed, the WWF wrote in December 2008 that the Greater Mekong is a biodiversity treasure. Now the organization notes : Over 350 new species including the world’s smallest deer, a “flying frog” and a 100 million-year old gecko

Science Magazine published an interesting article on how deforestation of the Brazilian Amazon rainforest provides only a temporary increase of living conditions to local populations. To the article: (…) on the basis of an assessment of 286 municipalities in different stages of deforestation, we found a boom-and-bust pattern in levels of human development across the

Urban sprawl poses many problems in terms of infrastructures to maintain, increased energy consumption and last but not least important health and environmental issues. With the economic downturn and high energy prices, people are sometimes returning to the urban cores. This leaves empty houses and even districts. In some cases these suburbs are litterally bulldozed
The end of urban sprawl ? Read More »
We have seen it previously, the Amazon Rainforest could become a desert because of deforestation and climate change. As I noted in May a three degrees Celsius increase would destroy it by up to 75 percent. But could global warming help the Sahara region becoming green again ? To National Geographic it could be the
Could the Sahara desert become green again ? Read More »
Further to an interesting article from the New Scientist on how we fail to act on climate change mitigation, I get to read that still many people are denying climate change. Indeed: Despite all this information (on climate change), opinion polls over the years have shown that 40 per cent of people in the UK
