Modeling the forest transition: forest scarcity and ecosystem service hypotheses.
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...
متن کامل[Forest ecosystem service and its evaluation in China].
Facing the relative lag of forest ecosystem service and estimation in China, this paper proposed to quickly carry out the research on the evaluation of forest ecosystem service. On the basis of the classification of forest ecosystem types in China, the service of artificial and semi-artificial forest ecosystems was investigated, which was divided into eight types, i.e., timber and other product...
متن کاملDeclining forest productivity in aging forest stands: a modeling analysis of alternative hypotheses.
Several explanations have been advanced to account for the decline in forest net primary productivity (NPP) with age in closed-canopy stands including the hypotheses that: (1) sapwood maintenance respiration rate increases, reducing the availability of carbon to support new growth; (2) stomatal conductance and hence photosynthetic efficiency decline; and (3) soil nutrient availability declines....
متن کامل“forest Ecosystem Services:
1. Forests (natural but also human-made or modified) are among the most important providers of ecosystem services for the whole world. 2. Based on scientific evidence, it is certain that: (a) Ecosystem services are essential to the survival of human beings. (b) Forest ecosystems operate and provide services on such a grand scale and in such intricate and little-explored ways that most cannot ef...
