Tropical forests and the global carbon cycle.
New data on the three major determinants of the carbon release from tropical forest clearing are used in a computer model that simulates land use change and its effects on the carbon content of vegetation and soil in order to calculate the net flux of carbon dioxide between tropical ecosystems and the atmosphere. The model also permits testing the sensitivity of the calculated flux to uncertain...

متن کاملEconomically optimal cutting cycle in a beech forest, Iranian Caspian Forests
The aim of this study was to determine the optimal cutting cycle in an uneven-aged beech forest in the North of Iran. First of all, a logistic growth model was determined for an uneven aged forest. Then, the stumpage price was predicted via an autoregressive model. The average stumpage price of beech was derived from actual timber, round wood, fire and pulpwood prices at road side minus the var...
متن کاملModelling the urban water cycle
Current urban water management practices aim to remove stormwater and wastewater efficiently from urban areas. An alternative approach is to consider stormwater and wastewater as a potential resource substitute for a portion of the water imported via the reticulated supply system. A holistic view of urban water resources provides the framework for the evaluation of the demand for water supply, ...
متن کاملThe Water Cycle across Scales
AMERICAN METEOROLOGICAL SOCIETY | 1743 T he transport and transformations of water substance in the global water cycle are of fundamental and primary importance for understanding the ecosystems, the land surface hydrology that supports them, and the management of water resources for humans. Th e water cycle is also critical for predicting weather, and the long-term climate balance of the planet...
