Signing their lives away: Liberia’s private use permits and the destruction of community-owned rainforest

A quarter of Liberia’s total landmass has been granted to logging companies in just two years, following an explosion in the use of secretive and often illegal logging permits, an investigation by Global Witness, Save My Future Foundation (SAMFU) and Sustainable Development Institute (SDI) shows. Unless this crisis is tackled …

Timing of carbon emissions from global forest clearance

Agricultural expansion and deforestation contribute to approximately 17% of global greenhouse-gas emissions. The fate of cleared wood and subsequent carbon storage as wood products, however, has not been consistently estimated. Now research fills this gap and shows that 30 years after forest clearance the percentage of carbon stored in wood …

Research charts growing threats to biodiversity 'arks'

Many of the world's tropical protected areas are struggling to sustain their biodiversity, according to a study by more than 200 scientists from around the world. But the study published in Nature includes research focusing on a reserve in Tanzania by University of York scientists that indicates that long-term engagement …

Pobha Reserve Forest faces threat

Jonai: Pobha Reserve Forest, situated on the outskirts of Jonai town is the lone reserve forest in the Jonai sub-division under Dhemaji Forest Division, which is on the verge of decline. This 10,000 square hectare of tropical rainforest with its rich bio-diversity and natural resources has always been a subject …

Protected tropical forests' biodiversity 'declining'

Despite having protected status, the biodiversity in a large number of tropical forests is still continuing to decline, a study has suggested. The authors said the findings should cause concern because the areas have been seen as a final refuge for a number of threatened species. Habitat disruption, hunting and …

Colour camouflage in Parambikulam forests

Melanism can be seen more in the evergreen habitat of the Western Ghats where the interiors of the forests are dark Melanism found in some animals at the Parambikulam forests in Palakkad district of Kerala has caught the imagination of wildlife enthusiasts. Recently, managers of the Parambikulam Tiger Reserve obtained …

Hills face disasters, say reports

Forest officials warn State of an environmental catastrophe in Nelliampathy The Forest Department has warned the State government of an environmental catastrophe in Nelliampathy, leading to disasters such as landslips, from destruction of forests by people and ecological factors. Giving the warning, a report, titled “Environmental catastrophes await Nelliampathy,” sent …

Amazon's doomed species set to pay deforestation's 'extinction debt'

The destruction of great swaths of the Brazilian Amazon has turned scores of rare species into the walking dead, doomed to disappear even if deforestation were halted in the region overnight, according to a new study. Forest clearing in Brazil has already claimed casualties, but the animals lost to date …

Beyond the borders: wildlife conservation in landscapes fragmented by plantation crops in India

This working paper describe the context and challenges of landscape-scale conservation amidst plantations and forests and other tropical ecosystems in the Western Ghats, India. Agricultural expansion has historically been the major global cause for the loss and fragmentation of natural ecosystems, and today remains one of the largest threats to …

U.N. Risks Investor Stand-Off On REDD By Delaying Work: Green Groups

Countries risk delaying much-needed private sector investment in slowing deforestation by dodging tricky issues such as how to protect the rights of forest dwellers, green groups said Thursday. Negotiators aim to finish work on how to measure the CO2 content of tropical forests by the year-end U.N. meeting in Qatar. …

Assessment of increasing threat of forest fires in Rajasthan, India using multi-temporal remote sensing data (2005-2010)

Rajasthan is the largest state of India experiencing recurrent forest fires. The present study determines forest burnt areas through remote sensing-based time series analysis. IRS P6 AWiFS satellite data covering March, April and May of six years (2005–2010) were used to cover all forest-fire events. The total forest burnt area …

Spatial pattern of standing timber value across the Brazilian Amazon

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 …

Brazil set to cut forest protection

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.

The effect of climate fluctuation on chimpanzee birth sex ratio

Climate and weather conditions, such as the North Atlantic Oscillation, precipitation and temperature influence the birth sex ratio (BSR) of various higher latitude species, including deer, elephant seals or northern human populations. Although, tropical regions show only little variation in temperature, climate and weather conditions can fluctuate with consequences for …

Fire-free land use in pre-1492 Amazonian savannas

The nature and scale of pre-Columbian land use and the consequences of the 1492 “Columbian Encounter” (CE) on Amazonia are among the more debated topics in New World archaeology and paleoecology. However, pre-Columbian human impact in Amazonian savannas remains poorly understood. Most paleoecological studies have been conducted in neotropical forest …

Water availability is the main climate driver of neotropical tree growth

Climate models for the coming century predict rainfall reduction in the Amazonian region, including change in water availability for tropical rainforests. Here, we test the extent to which climate variables related to water regime, temperature and irradiance shape the growth trajectories of neotropical trees. We developed a diameter growth model …

Slash-and-burn 'improves tropical forest biodiversity'

Slash-and-burn agricultural practices, banned by governments because of the risk of uncontrolled fires, provide better growing conditions for valuable new trees than more modern methods of forest clearance, a study suggests. Starting in 1996, researchers cleared 24 half-hectare areas of tropical forest in Quintana Roo state, in southern Mexico, using …

Break down boundaries in climate research

Scientists wanting to implement change must collaborate between disciplines. An ambitious Amazon study shows them how, says Paulo Artaxo.
