    Chongqing Municipality, located on the upper reaches of the Yangtze River, is one of China’s four largest megacities, comparable with Shanghai, Beijing, and Tianjin. In recent years, Chongqing and its surroundings have been experiencing severe environmental problems, such as urbanization, pollution, and deforestation, due to the rapid economic development of China’s inland region.

    Detailed observations of natural and anthropogenic disturbance events that impact forest structure and the distribution of carbon are essential to estimate changes in terrestrial carbon pools and the associated emissions and removals of greenhouse gasses. Recent advances in remote sensing approaches have resulted in annual and decadal estimates of land-cover change derived from observations using broad-scale moderate resolution imaging spectroradiometer (MODIS) 250 m–1 km imagery.

    Forests play an important role in the livelihoods of ethnic communities living in the south-eastern region, the Chittagong Hill Tracts (CHTs), of Bangladesh. Over decades, deforestation and land degradation have markedly affected ethnic peoples’ livelihoods in the CHTs. Although communities once managed extensive forest commons to support their livelihood needs, population explosion triggered fragmentation of common land leading to a gradual decline in livelihood opportunities.

    Testate amoebae that inhabit peat are sensitive indicators of water table position. In this study, we used testate amoebae in sediments from a mire in the western Alps (Lac du Thyl) to: (1) reconstruct the hydrology of the site over the last 7,000 years, (2) determine how hydrological changes affected testate amoebae diversity and (3) infer past trophic state shifts. The study site is located in one of the driest valleys of the Alps and is thus very sensitive to hydrological changes.

    The rapid development of the Vietnamese coffee industry caused widespread deforestation, land degradation, desertification, and soil and water degradation in the late 1990s. However, little is known about the impact of intensification of coffee farming on arthropod diversity in Vietnamese coffee agroecosystems.

    This study explores the role of gender as a factor in decision making about alternative land use options and in responses to new investment opportunities, which has received little attention to date. An observational study to determine the different factors affecting male and female decisions to change land use at the individual level in a forest margin landscape in Jambi (Sumatra, Indonesia) was combined with a set of role playing games (RPGs) designed to assess participant responses in a simulated social setting of women-only and men-only groups.

    Fossil pollen and plant macrofossils over the last 2000 years are documented from three small forest hollows in Southern Sweden. One of the sites is inside a 5 ha highly prized old growth mixed Fagus sylvatica and Picea abies forest of high biodiversity which has been protected since 1940. The other two hollows are located 400 and 700 m away in an outlying buffer zone established in 1995 which is mainly coniferous plantation forest.

    Deforestation in the biosphere reserves, which are key Protected Areas has negative impacts on biodiversity, climate, carbon fluxes and livelihoods. Comprehensive study of deforestation in biosphere reserves is required to assess the impact of the management effectiveness. This article assesses the changes in forest cover in various zones and protected areas of Nilgiri Biosphere Reserve, the first declared biosphere reserve in India which forms part of Western Ghats-a global biodiversity hotspot.

    Global conservation discourses and practices increasingly rely on market-based solutions to fulfill the dual objective of forest conservation and economic development. Although varied, these interventions are premised on the assumption that natural resources are most effectively managed and preserved while benefiting livelihoods if the market-incentives of a liberalised economy are correctly in place.
