Forest products value chains (FPVC) are complex networks of units incorporating different goals and beliefs. These units need to work together to generate the different elements of value. To study these value chains, a common representation and understanding of the different components of a value chain must be obtained. This will permit the evaluation of forest and industry strategies, supply c...
The forest products industry is a major component of Mississippi’s economic base. The need for a county-level forest inventory and the availability of decision support tools for locating forest product mills are of primary importance in attracting and sustaining the industry. The objective of this paper is to describe the pilot study, currently under development, for an integrated decision supp...
UNLABELLED BACKGROUND The default international accounting rules estimate the carbon emissions from forest products by assuming all harvest is immediately emitted to the atmosphere. This makes it difficult to assess the greenhouse gas (GHG) consequences of different forest management or manufacturing activities that maintain the storage of carbon. The Intergovernmental Panel on Climate Chang...
We evaluated the conservation attitudes of the local villagers living adjacent to the Kalakad-Mundanthurai Tiger Reserve in southern India 6 years after implementation of a World Bank funded eco-development project. We assessed attitudes towards three facets of conservation: the tiger, an emblematic species signifying India's commitment to wildlife conservation; the forest, a principle source o...
the present study modeled how future terrestrial net primary productivity (npp) changes spatiotemporally for the eastern mediterranean biomes of turkey using carnegie ames stanford approach (casa) model, moderate resolution imaging spectroradiometer (modis) data, the four regional climate change scenarios (rcp 2.6, rcp 4.5, rcp 6.0 and rcp 8.5), and such ancillary data as percent tree cover, la...
Introduction Community Based Forestry (CBF) implies commitment to the long term ecological, economic and social well being of forest dependent communities. CBF, or community scale sustainable forestry, constitutes a departure from industrial forestry due to this commitment to the preservation of the ecological integrity of the forest ecosystem in perpetuity and to the maintenance or improvement...
The environmental movement has emerged as a response to society’s concerns about the sustainability of Earth’s natural resources and the effects of human activity on the environment and on society’s wellbeing. Effects such as deforestation, air and water pollution, and resource depletion have shown to cause a decline in the quality of life of humans. In response, concerned citizens, non-governm...
An historical generalization about forest cover change in which rapid deforestation gives way over time to forest restoration is called "the forest transition." Prior research on the forest transition leaves three important questions unanswered: (1) How does forest loss influence an individual landowner's incentives to reforest? (2) How does the forest recovery rate affect the likelihood of for...
The forests of North America provide a variety of benefits including water, recreation, wildlife habitat, timber, and other forest products. However, they continue to face many biotic and abiotic stressors including fires, native and invasive pests, fragmentation, and air pollution. Forest health specialists have been monitoring the health of forests for many years. This paper highlights some o...
A simple model allows rapid comparison of typical baseline and policy scenarios which might be considered under international programs to avoid CO2 emissions caused by forest clearing, such as REDD (Reducing Emissions from Deforestation and Forest Degradation). These tests of REDD policy scenarios can also include CO2 stored in forest products. The value of avoided emissions can also be determi...
