Globalization and Forest Resurgence: Changes in Forest Cover in El SalvadorBackgroundThe authors study certain globalization impacts in land-use change in El Salvador. The legacy of war, remittances and international migration are among other factors that have allowed tree resurgence even in highly urban populated areas. This study tracks the different trajectories of forest recovery by analysing remote-sensing satellite images from 1970's to the early 2000's. Open access copy available |

Mapping Species Composition of Forests and Tree Plantations in Northeastern Costa Rica with an Integration of Hyperspectral and Multitemporal Landsat ImagerybackgroundThis article discusses the improvement in accuracy of remote sensing to monitor and evaluate reforestation projects by combining moderate-resolution and hyperspectral imagery with multi temporal, multispectral data. The combination of these technological monitoring methods allows researchers to accurately classify general forest types and tree plantations by species composition. Open access copy available |
Land Cover Change in Colombia: Surprising Forest Recovery Trends between 2001 and 2010backgroundThis study mapped annual land-use and land-cover from 2001 to 2010 in Colombia using MODIS (250 m) products coupled with reference data from high spatial resolution imagery (QuickBird) in Google Earth. Research Goals & MethodsThe authors evaluated land cover change at four spatial scales: country, biome, ecoregion, and municipality. Open access copy available |
Methodology for Comparative Analysis of Sustainability in Agroforestry SystemsbackgroundThis paper analyses different forms of agroforestry systems, including political and institutional linkages in the Caí and Taquari river valleys of the Brazilian state of Rio Grande do Sul in an effort to determine their sustainability.

Ecological Restoration of Red Sanders (Pterocarpus santalinus L.) Forests – An Adaptive Collaborative Modelling Supported ApproachBackgroundRed Sanders (Pterocarpus santalinus L.) is an endemic and endangered tree species in souther India that is highly valued for its timber uses. Both anthropogenic and abiotic factors have led to the fragmentation and degradation of the Red sanders habitat. This project, which took place in Eastern Ghats: Kadapa, Southern Andhra Pradesh in July 2011, seeks to understand Red Sanders forest and explore the possibility for restoration.

Monitoring Forest Degradation in Tropical Regions by Remote Sensing: Some Methodological IssuesBackgroundThis review examines different remote sensing techniques to monitor vegetation cover at a regional scale. The objective was to discuss implications related to monitoring of open forest degradation. Research Goals & MethodsTechniques include methods to track both spatial and temporal changes in structure and function associated with land use change. Open access copy available |

Patterns of Carbon Sequestration in Forests of Western Ghats and Study of Applicability of Remote Sensing in Generating Carbon Credits through Afforestation/ReforestationBackgroundUsing ground-based observations coupled with satellite remote sensing, this study aims to estimate the potential of the forests of Radhanagari Wildlife Sanctuary (Western Ghats, India) to sequester atmospheric carbon dioxide and to identify land which has the potential for reforestation activity under the Clean Development Mechanism.

Monitoring Mangrove Forest Dynamics of the Sundarbans in Bangladesh and India using Multi-Temporal Satellite Data from 1973 to 2000BackgroundIn the Sundurbans of India and Bangladesh, the authors measured the extent and condition of the mangrove forest at three intervals using GeoCover datasets (Landsat MSS, TM, ETM+) with the goal of assessing the current extent of the remaining forest, measuring change in the extent of the forest in different time periods, and identifying areas of intensive deforestation or degradation and changes in patterns of canopy density.
