Abstract Human intervention in forested ecosystems is hoped to perform a fundamental shift within the next decade by reverting current forest loss—a major source of CO 2 emissions—to net gain taking up carbon and thus aiding climate change mitigation. The demanded extensive establishment forests will local surface energy fluxes, with it climate, addition competing food fiber production for land...

The Federal Constitution of 1988 established the decentralization competence to legislate on environmental issue, and, consequently, municipality environment, including issue urban afforestation. objective this article is analyze afforestation, based legislation that deals with subject, diagnosing main problems derived from inadequate either by choosing wrong species or lack maintenance and mon...

Habitat fragmentation is widely considered a primary threat to biodiversity. In this paper, we analyze incentive-based policies designed to reduce forest fragmentation in the coastal plain region of South Carolina. Our approach integrates an econometric model of land use with simulations that predict the spatial pattern of land-use change. We analyze how subsidies for afforestation affect distr...

Abstract Mathematical programming is used to examine the economic potential of greenhouse gas mitigation strategies in U.S. agriculture and forestry. Mitigation practices are entered into a spatially differentiated sector model and are jointly assessed with conventional agricultural production. Competition among practices is examined under a wide range of hypothetical carbon prices. Simulation ...

In the developing process of urbanization in China, PM2.5 pollution has become a problem that must be faced. Greenway, especially those in the community, is the important green infrastructure to improve ecological environment in urban areas, which plays a crucial role in PM2.5 reduction. With basic cognitive analysis on definitions and characteristics of community greenway and PM2.5, this paper...

Deliberate anthropogenic introductions of exotic trees to NW Europe are not particular new; traces of planting near the castles and monasteries dates back to the late Roman period and early medieval age [1]. The first reforestation and forest culture initiatives in Norway were taken in the 1740s [2-5], and larch plantations in western Norway were established in the 1780s [6]. However, the ideas...

We examine changes in canopy cover for adult western juniper from the 1960s to 1994 in central Oregon using repeat aerial photography. We compare changes at four sites with a land-use history of minimal anthropogenic disturbance to changes on adjacent sites that have a disturbance history more typical of central Oregon rangelands. Canopy cover increased at all sites, but afforestation on sites ...
