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.

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.

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.

This study assesses the costs and revenues resulting from this system and the impacts to agriculture. Research Goals & MethodsField research was conducted to assess survival, food crop yield, financial feasability. Available with subscription or purchase |
Fire Control as a Simple Means of Promoting Tropical Forest RestorationbackgroundThis study investigates whether or not fire exclusion allows grasslands to regenerate to forest in a timeframe suitable for reforestation efforts. The researchers compare tree species richness, dbh, diameter at ground height (DGH), and total woody biomass accumulation in 2 plots that have been protected from fire. They measure the size and amount of above ground biomass in plots that have been protected from fire for 12 and 32 years respectively in Kibale National Park, Uganda. Open access copy available |
Are Mangroves Worth Replanting? The Direct Economic Benefits of a Community-Based Reforestation ProjectbackgroundThis study examines the socioeconomic impacts of a community-led reforestation project in the Philippines through a survey of the local fishers over 10 years after replanting. The wider objective of the study was to obtain greater data on the local economic value of mangroves and present it as a comparison to other land uses such as development and aquaculture.

Evaluación técnica y financiera de la silvicultura desarrollada en un bosque natural de la Guayana venezolana (Technical and financial evaluation of silvicultural management in the Venezuelan Guayana)Los autores analizan el funcionamiento de una empresa forestal que ejecuta, desde 1996, un plan de ordenación y manejo forestal en un bosque seco tropical, El Dorado- Tumeremo, con una superficie productiva 66 000 ha (Estado Bolívar, Venezuela). Se aprovechan unas 30 especies según diámetros mínimos de corta, clasificadas según su potencial comercial: las comerciales (Hymenaea courbaril, Pouteria caimito, Spondias mombin, Cordia alliodora, Andira sp., Manilkara bidentata y Peltogyne pubescens), las potencialmente comerciales (Cordia bicolor, Fagara martinicense, Tetragastris panamensis, Ceiba pentandra, Brosi- mun alicastrum, Aspidosperma megalocarpum, Astronium lecontei) y las que no tienen valor com Open access copy available |
Florestas e Bioenergia (Forests and Bioenergy)This article is an overview of the present status and prospects for the use of planted forests for bioenergy in São Paulo state, Brazil. The author compiled data to estimate the state's land area suitable for forest biomass production. Sugarcane and eucalyptus plantations were compared in terms of energy production and costs, with eucalyptus being slightly more than half as expensive / unit energy / hectare as sugarcane. Finally, a series of policy recommendations necessary to facilitate the use of forests for energy production. Open access copy available |

Restauración de Bosques en territorios indígenas de Chiapas: modelos ecológicos y estrategias de acción (Restoration of forests in Indigenous territories of Chiapas: ecological models and action strategies)EspañolAntecedentesLos bosques montanos del sur de México se han fragmentado severamente y su estructura y composición florística se han visto alteradas debido a la agricultura tradicional y al crecimiento demográfico. En extensas áreas de Chiapas, la restauración forestal no solo es una necesidad urgente, sino que también representa una opción viable para la recuperación de productos y servicios que podrían ser utilizados en el futuro de manera sustentable.
