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.

Reforestation of the Abutia Plains by indigenous communities in the Volta Basin (Ghana) ex post evaluation

Background

Deforestation an degradation in Ghana has been an on-going issue, with one-third of the country's forested area reporting lossed between 1955 to 1972. This has been due to increased human acitivities and the effects have been further aggravated by socio-economic issues. In 1994, the government of Ghana adapted a Forest & Wildlife Policy and established a program for reforestation that involved a variety of stakeholders.
