Disturbance, Recovery and Resilience in Tropical Forests: A Focus on the Coastal Peat Swamp Forests of Malaysian BorneoBackgroundThis thesis represents four years of work investigating the long-term ecological changes that have occurred in the coastal peat swamp forests of Sarawak, in Malaysian Borneo over the Late Holocene. Research Goals & MethodsThree peat cores were extracted from sites along the coast of northern Borneo and fossil pollen and charcoal analysis performed on them in order to look at how vegetation has changed in the past, and what factors may have caused disturbances to the baseline forest communities Open access copy available |
Ecological Engineering for Successful Management and Restoration of Mangrove ForestsBackgroundThis article takes a look at the reasons why many mangrove restoration projects fail, and provides key recommendations for improving the success rate of mangrove restoration projects.

The Rain–Runoff Response of Tropical Humid Forest Ecosystems to Use and Reforestation in the Western Ghats of IndiaBackgroundThis study expands on a previous study in the Western Ghats of India (Uttar Kannada, Karnataka State), that suggested a greater occurrence of infiltration-excess and potentially higher streamflow in degraded and reforested areas. Analyzing rainfall–streamflow data, the authors attempt to determine the impacts of different land cover types on stream discharge hydrograph components (viz, total flow, quickflow and delayed flow), the dominant stormflow pathways, and the impact of reforestation efforts on these processes.

Effects of Afforestation on Water Yield: A Global Synthesis with Implications for PolicybackgroundThis study synthesizes data from global studies on reforested and afforested areas and compares these to grassland and shrubland areas. In particular, the authors measure response to water runoff. Available with subscription or purchase |
Modelling the Effect of Forest Cover on Shallow Landslides at the River Basin ScalebackgroundThis study analyzes soil models that can be used to help predict soil erosion which are useful to prioritize reforestation areas of watersheds. Research Goals & MethodsThe researchers tested the models in a river basin in Ecuador. They collected data for soil moisture/matric potential, depth, and rainfall. Vegetation (overland flow resistance coefficient) and root cohesion data were derived from the literature, as was the evapotranspiration rate. Open access copy available |
Management of sedimentation in tropical watershedsBackgroundThe sedimentation of reservoirs is a serious problem throughout the tropics, yet most attempts to control sedimentation in large river basins have not been very successful. Reliable information on erosion rates and sources of sediments has been lacking. This paper discusses some of the limitations in estimating erosion and sedimentation and encourages development of specific sediment budgets in order to extrapolate equations and generate management procedures.

Restoring dense vegetation can slow mountain erosion to near natural benchmark levelsBackgroundTropical mountain areas may undergo rapid land degradation as demographic growth and intensified agriculture cause more people to migrate to fragile ecosystems. To assess the extent of the resulting damage, an erosion rate benchmark against which changes in erosion can be evaluated is required. Benchmarks reflecting natural erosion rates are usually not provided by conventional sediment fluxes, which are often biased due to modern land use change, and also miss large, episodic events within the measuring period.

Effect of Reforestation using Tectona grandis on Infiltration and Soil Water RetentionBackgroundIn this study, researchers examine the effect of teak (Tectona grandis) reforestation on soil infiltration and water retention in Sri Lanka. They compare the reforested site (12 years after planting) with a corn field and an abandoned pasture dominated by Imperata cylindrica grass. Available with subscription or purchase |
Using ecosystem valuation to protect the Atlantic Rainforest: the case of the Oasis ProjectBackgroundThe article explores the Oasis Project, which is a payment for ecosystem services program that aims to protect the Atlantic Forest in Brazil. The program was established in 1990 in response to the destruction of the forest. The Oasis Project aims to provide drinking water to approximately 17 million in the Sao Paulo metropolitan region by financially compensating landowners engaged in maintaining forest cover in their proprieties.
