Electric utilities in the US have initiated forestry projects to conserve energy and to o€set carbon dioxide (CO2) emissions. In 1995, 40 companies raised US$2.5 million to establish the non-pro®t UtiliTree Carbon Company which is now sponsoring eight projects representing a mix of rural tree planting, forest preservation, forest management and research e€orts at both domestic (Arkansas, Louisiana, Mississippi, and Oregon) and international sites (Belize and Malaysia). The projects include extensive external veri®cation. Such forestry projects Ð properly documented, monitored and veri®ed Ð should be a component of domestic and international strategies to address greenhouse gas (GHG) emissions, due to GHG bene®ts,...
This paper summarizes the main results of a study on the costs of abatement of CO2 emissions in Brazil. It discusses three possible futures for the long run (2010 and 2025) activity of the Brazilian economy and -- with the help of a linear programming model for Brazil's energy sector -- three scenarios for energy production and use. One of these scenarios illustrates the possibility of halving future carbon emissions originating from energy generation and consumption, with relatively small increases in energy associated costs and investments. This abatement scenario would require, on the supply side of the Brazilian energy balance, increased amounts of hydropower, ethanol and bagasse from sugarcane, plus wood and...
Concern over the greenhouse effect has led to increased interest in the regional implications of changes in temperature and precipitation patterns for water resources. The impact of greenhouse gases on water availability and quality is likely to be significant, though still poorly understood. Both the development of scenarios involving temperature and precipitation variation and the use of hydrologic simulation models allows researchers to study the impact of these changes on runoff and water supply.

These data were compiled to identify potential contributions of drought and inundation tolerance to vegetation composition along the Colorado River. Objective(s) of our study were to quantify physiological and growth responses of different plant species to drought and inundation. These data represent measurements taken on container plants in a greenhouse, and hydrological niche values based on field monitoring data that are published elsewhere. These data were collected in summer of 2022 at the Northern Arizona University Research Greenhouse Complex. These data were collected by Northern Arizona University and U.S. Geological Survey scientists in a greenhouse and laboratory setting. These data can be used to assess...
