Clarifying factors affecting forest area changes is critical to implementing REDD+ scheme properly. We analyzed some socio-economic factors and clarified their relationships with deforestation in Cambodia for the period of 2002 to 2010. A panel data analysis was conducted for 18 provinces, while six other provinces were deleted from the list because only a small amount of their land was forested. Time effects, cross-sectional dependence, serial correlation in idiosyncratic errors, and heteroskedasticity were tested, and robust variance matrix estimations were obtained to solve the problems of heteroskedasticity and serial correlation. The model estimation results showed that population, gross agricultural production and large-scale plantation development have negative impacts on forest area changes. On the other hand, the impacts of rice cultivation, gross industrial production, household income and house floor area by household were found not to be significant. Overall, however, the results indicated that forests in Cambodia still face pressure from the increases in population, agriculture production, and the enlargement of land development. As the increase in productivity of agriculture gives a better use of current agricultural land and lessens the pressure on forest, intensifying agriculture is important. It is also important to develop industry and other economic ventures to grow national economy while not imposing pressure on forest. This research reminds decision makers to use discretion when developing large-scale plantations
The State Forest Company of Indonesia launched its Company-Community Forestry Partnerships system on the island of Java in 2001 (PHBM system). We examined the PHBM's effects on the economic lives of participating villagers through a case study in Madiun, East Java. We specifically examined the potential and limits of the PHBM's contribution to villagers' livelihoods by quantitatively evaluating (i) the system's impact on household livelihoods and (ii) the continuity of its impact. Of households engaging in PHBM, 45.6% had more than half their arable land in the forest, and 10.0% of households had arable land only in the forest. The bulk of non-timber forest products, mostly fuelwood, was collected in the forest. Among villagers earning an income, 12.2% earned more than half via the PHBM, which was the only source of cash income for 2.2% of the engaged villagers. For some households, PHBM has helped significantly improve their livelihoods. However, the benefits derived from the PHBM were tempered by problems of quality, quantity, and continuity. The benefit of the system could be increased by providing preferential opportunities (to access farmland in the forest and/or cash income) to small-scale or impoverished farmers by improving the usage of intercropping land under planted trees, and promoting small business as a group enterprise.Discipline: Forestry and forest products Additional key words: Perum Perhutani, teak forest management
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
