Variation in Canopy Structure, Light and Soil Nutrition Across Elevation of a Sri Lankan Tropical Rain Forest

Background

This study aims to examine differences in resource availability across elevation and geology in mixed dipterocarp forest by measuring light, soil nutrition and soil water availability in relation to forest structure in southwest Sri Lanka.

Structural Properties of Two Types of Mangrove Stands on the Northwestern Coast of Sri Lanka

background

This article compares the structural diversity of six mangrove stands of both estuarine and island-fringing types in Puttalam lagoon and Dutch Bay in northwestern Sri Lanka.

Research Goals & Methods

Using belt transects, the authors measured floristic composition, tree height and leaf-area index and calculated density, basal area and mean stand diameter. Standing above-ground biomass was also measured and compared to dbh using destructive sampling methods.

Growth, biomass, carbon storage and nutrient distribution in Gmelina arborea stands on red lateritic soils in central India

Background

Large-scale plantations are being established on degraded lands in India to restore the productivity of these soils and landscapes and to sequester atmospheric carbon. Gmelina arborea is a fast-growing indigenous tree used for timber, fuelwood, pulp and fodder already in use in reforestation projects. However, its growth and biomass production has been inadequately studied, particularly in the poor red laterite soils that dominate degraded landscapes.

Ectomycorrhizal Colonization and Seedling Growth of Shorea (Dipterocarpaceae) Species in Simulated Shade Environments of a Sri Lankan Rain Forest

Background

This study examines how the degree of ectomycorrhizal (EM) colonization of potted Shorea spp. is associated with the amount and quality of daily photosynthetic photon flux density (PFD).

Spatial Interpolation of Carbon Stock: A Case Study from the Western Ghats Biodiversity Hotspot, India

Background

This study in the Anamalai Hills of the Western Ghats estimates the biomass and carbon stock of major tropical forest types in India and attempts to identify suitable interpolation techniques to map carbon stock.

REDD+ Readiness Implications for Sri Lanka in Terms of Reducing Deforestation

Background

This study constructs a historical reference level of emissions from deforestation in Sri Lanka using available forest inventory data and in situ carbon density data. It also attempts to identify drivers of deforestation in Sri Lanka and to estimate the opportunity cost and possible climate benefits of forest conservation.

Carbon sequestration versus bioenergy: A case study from South India exploring the relative land-use efficiency of two options for climate change mitigation

background

This study explores avenues to meet increased rural electricity demand with carbon emissions mitigation. The study compares the option of energy derived from gasification of biomass from forest plantations to energy derived from fossil fuels, with forest plantations used as a carbon sink.The case study uses power demand, land requirements, and management approaches for Hosahalli village, Karnataka, pop. 218.

Forest conservation, afforestation, and reforestation in India: Implications for forest carbon stocks

Background

Considering India’s goal to have 1/3 of their land area forested by 2012, this article assesses the implications of past and current forest conservation and regeneration policies and carbon stock programs.

Assessing the Mitigation Potential of Forestry Activities in a Changing Climate: A Case Study for Karnataka

Background

The Clean Development Mechanism (CDM) of the Kyoto Protocol has two goals: promote climate mitigation activities that offset carbon dioxide entering the atmosphere, and promote sustainable economic development. Afforestation and reforestation (A/R) projects can often meet these two goals simultaneously. India, which ratified the Kyoto Protocol in 2002, has sought to implement A/R projects as part of the CDM.

Monitoring Mangrove Forest Dynamics of the Sundarbans in Bangladesh and India using Multi-Temporal Satellite Data from 1973 to 2000

Background

In 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.
