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.

The Impact of Forest Use and Reforestation on Soil Hydraulic Conductivity in the Western Ghats of India: Implications for Surface and Sub-Surface Hydrology

background

This article presents research on the surface and sub-surface permeability of degraded and restored forests and their dominant stormflow pathways  in the humid tropics of Uttar Kannada district, Karnataka, India. The authors attempt to determine to what extent field saturated hydraulic conductivity (K*) isaltered due to long-term forest degradation as compared to other studies in the humid tropics. They quantify changes in permeability following forestation of plantations and degraded landscapes and investigate the likely effect of wet-season conditions and the implications this has for predicting hydrologic consequences of forest degradation.

The Rain–Runoff Response of Tropical Humid Forest Ecosystems to Use and Reforestation in the Western Ghats of India

Background

This 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.

Mahogany and Kadam planting farmers in South Kalimantan: the link between Silvicultural activity and stand quality

Background

Incentive structures in Indonesia have promoted forest plantations conducted and managed in partnership with local farmers. This paper examines the relationship between farmers’ socio-economic characteristics, silvicultural activity and the quality of their mahogany (Swietenia macrophylla) and kadam (Anthocephalus/Neolamarkia cadamba) plantation stands in two independent case study villages in South Kalimantan Province, Indonesia.

China's sloping land conversion program: Institutional innovation or business as usual?

Background

China’s Sloping Land Conversion Program (SLCP) is the largest land retirement program in the developing world, having the goal of converting 14.67 million hectares of cropland to forests by 2010, primarily targeting high-slope and marginal lands. The program is being implemented in more than 2000 counties across 25 provinces in China and affects tens of millions of rural households using PES models to promote afforestation.

Effect of Reforestation using Tectona grandis on Infiltration and Soil Water Retention

Background

In 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.

Tree species effects on soil properties in experimental plantations in tropical moist forest

Background

Forest soil properties are influenced by the complex interactions of vegetation, soil type, geology, management, and climactic patterns. Tree species can differ in their long-term effects on soils. This study resamples one of the earliest replicated experimental sites at La Selva Biological Station, Costa Rica, used to examine the effects of native tropical tree species on soil properties, to examine longer term effects on soil properties.
