Economic Analysis of Sengon (Paraserianthes falcataria) Community Forest Plantation, a Fast Growing Species in East Java, IndonesiabackgroundThis article examines Paraserianthes falcataria (Sengon) mixed community forest plantations in East Java, Indonesia. The Indonesian government launched a timber / reforestation program in 1990 but only 20% of projected timber supply has come from these plantations, and total reforested area is far below targets. Before 1997, forest resources were held by concession companies, and local access rights were denied. Under reforms however, government decentralization gave local governments more authority to manage their resources, and extensive deforestation (and low levels of reforestation) has followed.

Effect of Land Prices, Transportation Costs, and Site Productivity on Timber Investment Returns for Pine Plantations in ColombiabackgroundThis study assesses the importance of land costs, site quality, and forest location on financial returns of forestry investments. Goals & MethodsThe factors mentioned above were analyzed using data from pine plantations in the Andean region of Colombia. Researchers determined site quality based on annual growth rates and they calculated comparative return on forest investment based on sales of wood, market prices, wood transport costs, and bare land costs.

Timber Investment Returns for Selected Plantations and Native Forests in South America and the Southern United StatesbackgroundThis study examines the value of timber investments in South America. Exotic Eucalyptus in the southern cone (Argentina + Chile) are the most profitable, with Internal Rate of Return of 13-23%, followed by exotic loblolly pine (Pinus taeda), whereas investments in the southeast USA is less profitable.

Development of Soilless Culture Methods for Production of Moringa (Moringa oleifera Lam.) Root and Leaf BiomassbackgroundMoringa is a valuable tropical agroforestry species with a fruit rich in nutrients. This study tested soilless (hydroponic) Moringa cultivation methods given that past research on tissue culture (vegetative reproduction) has shown difficulty in transfer to soil. Research Goals & MethodsIn this study, dehulled seeds had a high germination rate (65%), whereas hulled seeds had low germination. Available with subscription or purchase |
