The acreage of creation, restoration (re-establishment or rehabilitation), and enhancement that is required by regulatory agencies, including local governments, to compensate for impacts to wetlands is usually greater than the acreage of impact. This difference is expressed as a ratio (a mitigation ratio) of the area required for compensation vs. the area of impact. For example, a ratio of 3:1 ...

Water is an essential yet constrained commodity for human communities and ecological systems depend on it. With population growth and economic development, water resource is increasingly declining. Over the past two decades, because of changes in population and climate, and relative welfare increase, the per capita consumption of water has increased. Thus, optimal use of available water resourc...

Chlorophenoxy herbicides are used both in cereal grain agriculture and in nonagricultural settings such as right-of-ways, lawns, and parks. Minnesota, North Dakota, South Dakota, and Montana grow most of the spring and durum wheat produced in the United States. More than 90% of spring and durum wheat is treated with chlorophenoxy herbicides, in contrast to treatment of approximately 30% of wint...

The objective of this analysis was to integrate hydrologic, agronomic, and economic methods evaluate various management strategies by changing crop acreage better manage the declining resources Ogallala aquifer. A non-linear optimization model used estimate optimal water use, mix, yield, net returns over a 50 year period under dryland deficit irrigation scenarios in Texas High Plains. Results i...

EXECUTIVE SUMMARY: This paper examines Latino migration to a " new destination " county in the southeastern U.S., Hall County, Georgia, where environmental equity is considered in terms of Latino communities' walking access to public and private parks in the county. Park access is considered an environmental equity or justice issue because some research shows less park acreage available to mino...

Weed control is generally the first major decision to be made once alfalfa has germinated. Managing weeds in a timely manner is necessary to provide maximum production of high quality alfalfa hay. A poor weed management decision can lead to stand loss, poor quality hay, unacceptable weed control, alfalfa injury and a loss of money. Herbicides are applied to 75% of newly planted alfalfa in Calif...

NDVI obtained from satellite at the pixel over the area of crop cultivation would represent a specific temporal profile, which could be discriminated from that of other land use. In this study, the author attempted to estimate the acreage of winter wheat sown area using multitemporal NDVI obtained from NOAA-AVHRR data. The study site was selected in the Huang-Huai-Hai plain in China, where the ...

There are few empirical tests that support the existence of information asymmetry. We add to this literature using bid-ask spread to capture differences in the level of information asymmetry just prior to the announcement of an open market acquisition of acreage or reserves by U.S. oil and gas firms over the period 1993 to 2011. Acreage is an area of land that is believed to contain reserves an...
