Combinations of trees and crops in the taungya method as applied in Thailand

Background

In this article, the authors desribe the 'taungya' methods used in Thailand for reforestation and agroforestry in the 1980s. This method was primarily used under theForest Village Programme, during which landless people were given 1.6 ha of land to reforest and raise their crops.

Carbon Sequestration and Plant Community Dynamics Following Reforestation of Tropical Pasture

Background

Conversion of abandoned cattle pasture to secondary forest in the tropics is a potential means to increase carbon sequestration as well as to enhance local biodiversity. This study uses data from a long-term tropical reforestation project – Luquillo Experimental Forest in Puerto Rico – to estimate rates of above- and belowground carbon sequestration.

Can Native Tree Species Plantations in Panama Compete with Teak Plantations? An Economic Estimation

background

Panama has high rates of primary forest conversion, resulting in depleted timber resources. In response, the timber plantation industry is growing to meet demand, often with non-native species. This study compares the economic feasibility of using native tree species vs non-native species for plantation forestry.

Restoration of dry tropical forests in Central America: A review of pattern and process

Background

Much information on restoration and management exists for wet tropical forests of Central America but comparatively little work has been done in the dry forests of this region. Such information is critical for reforestation efforts that are now occurring throughout Central America. This paper describes processes of degradation due to land use and provides a conceptual framework for the restoration of dry tropical forest, of which less than 2% remains intact.
