NEW DELHI: Expressing concern over recent tiger deaths in the country, Environment and Forests Minister Jayanthi Natarajan said her ministry is constantly looking into the reasons for it. "We will have to take a look at the reasons. 17 are natural deaths, and we will look into the other deaths. We are constantly looking at the reasons. Well, poaching, you know, is an important reason which we are actively considering. The other reasons if it is a man- animal conflict we are already addressing those causes," Natarajan told media.

The Tree Authority Committee has approved the hacking of more than 822 trees for various developmental projects. Municipal commissioner Sitaram Kunte also directed the civic officials to start a survey and prune weak and dangerous trees from Tuesday. Kunte announced his decision while chairing the Tree Authority Committee meeting on Monday.

In the Neotropics the predominant pathway to intensify productivity is generally thought to be to convert grasslands to sown pastures, mostly in monoculture. This article examines how above-ground net primary productivity (ANPP) in semi-natural grasslands and sown pastures in Central America respond to rainfall by: (i) assessing the relationships between ANPP and accumulated rainfall and indices of rainfall distribution, (ii) evaluating the variability of ANPP between and within seasons, and (iii) estimating the temporal stability of ANPP.

The Amazon is a globally important system, providing a host of ecosystem services from climate regulation to food sources. It is also home to a quarter of all global diversity. Large swathes of forest are removed each year, and many models have attempted to predict the spatial patterns of this forest loss. The spatial patterns of deforestation are determined largely by the patterns of roads that open access to frontier areas and expansion of the road network in the Amazon is largely determined by profit seeking logging activities.

While its Latin American neighbors move forward with national climate laws, Argentina is backsliding on actions to tackle its greenhouse gas emissions as the country struggles to meet energy demand from a fast-growing middle class.

Argentina's GDP grew 7.3 percent last year, driving demand for energy that is overwhelmingly derived from fossil fuels. According to Argentine Institute of Petroleum and Gas (IAPG), energy demand rose 5.1 percent in 2011.

The Capital Development Authority (CDA) has imposed a fine of Rs 50,000 per tree on a private builder for cutting trees and has asked him to compensate the heavy loss to the environment by planting the same number of trees.

Earlier, Prime Minister’s Task force on Islamabad Chairman Faisal Sakhi Butt took serious notice of the chopping of 40-year-old trees by the builder and had directed the CDA to take stern action against him.

Industrial agricultural plantations are a rapidly increasing yet largely unmeasured source of tropical land cover change. Here, we evaluate impacts of oil palm plantation development on land cover, carbon flux, and agrarian community lands in West Kalimantan, Indonesian Borneo. With a spatially explicit land change/carbon bookkeeping model, parameterized using high-resolution satellite time series and informed by socioeconomic surveys, we assess previous and project future plantation expansion under five scenarios.

The area under forest cover in Karnataka has increased by four square kilometres, according to a latest report of the Forest Survey of India. It says the change has been noticed in the assessment year of 2009, compared to the survey carried out in 2008. The report was put in the public domain recently.

Sources in the State government told The Hindu that the change for the better was being seen for the first time in about a decade. What was noteworthy was that at a time when forests were being “plundered in terms of their flora and fauna and conservationists facing a tough challenge,” the increase, though negligible, marks a refreshing change.”

The sound of chainsaws in the Amazon rainforest has faded in recent years as deforestation has slowed, last year dropping to less than one-third of its long-term average. But last week, the lower house of Brazil’s
National Congress passed a bill that observers say could drastically reduce forest protection.

SHILLONG: With each passing day, the thick lush forest cover in West Khasi Hills district is fast thinning presenting a very worrisome sight. While the primary reason for the loss of forest cover points towards the rampant burning of firewood to generate charcoal, what is worrying is that even persons who own vast areas of forests do not seem to care or incline to protect their assets for the future generations.

Concerned over the dwindling forest cover especially in West Khasi Hills and the wanton burning of firewood for charcoal, Deputy Chief minister in charge of mining and geology Bindo M Lanong said,
