Water quality is a major environmental issue. Pollution from nonpoint sources is the single largest remaining source of water quality impairments in the United States. Agriculture is a major source of several nonpoint-source pollutants, including nutrients, sediment, pesticides, and salts. Agricultural nonpoint pollution reduction policies can be designed to induce producers to change their pro...

Nitrogen oxides (NO x = NO + NO2) are a primary component of air pollution-a leading cause of premature death in humans and biodiversity declines worldwide. Although regulatory policies in California have successfully limited transportation sources of NO x pollution, several of the United States' worst-air quality districts remain in rural regions of the state. Site-based findings suggest that ...

The area of wireless sensor network is wide & there are various kinds of sensor devices are used in mobile applications. Sensors monitor the environmental activities like air pollution, noise level, water level, greenhouse monitoring, agriculture monitor etc which grows & generates greater interest & becomes a challenge for finding out the graph or curves for the large amount of data sets. In t...

optimistic. He found the theme of that statement — of what “will” happen in the future — to be troubling in that, in the 1920s, a radical change in technology, with similarities to biotechnology, was championed by luminaries such as Thomas Edison and Henry Ford: to replace hydrocarbons with carbohydrates. Despite broad support, including deans of MIT and Harvard, for the concept of manufactured...

Synopsis There is great concern among the public in general, and consumers in particular, about the quality of the environment in relation to agriculture. Such concerns focus on issues such as pollution from agriculture, the quality of landscapes, animal welfare and food safety. As a result, many countries have developed a range of standards, codes of good practice and other policy measures. Th...

This paper estimates costs associated with water pollution in the Olifants River Water Management Area (WMA) in South Africa, and, more specifically, the area represented by the Loskop Dam Water User Association. We focus on the impacts of salinisation on commercial irrigated agriculture, and of microbial pollution on the general population of the WMA, many of whom do not have access to municip...
