Pakistan is an agrarian country, and the main agricultural products are cotton, wheat, rice, sugarcane, fruits, and vegetables. Fuels derived from agricultural sources offer an alternate to the rapidly increasing price of petroleum fuels and the increasing scarcity and the toxicity of such fuels. This paper seeks to examine the impact of biofuels industry on the Pakistan economy. The paper furt...

The Soil and Water Assessment Tool (SWAT) was calibrated for hydrology conditions in an agricultural watershed of Orestimba Creek, California, and applied to simulate fate and transport of two organophosphate pesticides chlorpyrifos and diazinon. The model showed capability in evaluating pesticide fate and transport processes in agricultural fields and instream network. Management-oriented sens...

This paper examines the effects of environmental zoning policies on lakefront land development, sorting, and economic welfare in a model where agents are heterogeneous in preferences and income. Agents consume lakefront amenities that are endogenous to development and the sorting process yields lakes which differ by amenities and frontage prices. Our findings include the following: i) lakes bec...

The potential presence of steroid hormones in runoff from sites where biosolids have been used as agricultural fertilizers is an environmental concern. A study was conducted to assess the potential for runoff of seventeen different hormones and two sterols, including androgens, estrogens, and progestogens from agricultural test plots. The field containing the test plots had been applied with bi...

In this paper an applied general equilibrium model for the Extremadura region is presented. Our aim is to show the importance of agricultural subsidies in this economy, that it is a distinctive characteristic of this region. To achieve this purpose, we analyse the effects of a supression of these subsidies, using different scenaries related to the labour market and tax compensation. Model param...

Differences in the properties of organic phosphorus (P) sources, particularly those that undergo treatment to reduce soluble P, can affect soil P solubility and P transport in surface runoff. This 2-yr field study investigated soil P solubility and runoff P losses from two agricultural soils in the Mid-Atlantic region after land application of biosolids derived from different waste water treatm...

Agroforestry has the potential to contribute greatly to Pacific island development efforts. However, success will depend on fully realizing the social implications of agricultural research on island cultures. Agroforesters must recognize their role as "agents of change." Because of this, they must strive for the involvement of the community in all stages of their research. The applied research ...

BACKGROUND The associations of pesticide exposure with disease outcomes are estimated without the benefit of a randomized design. For this reason and others, these studies are susceptible to systematic errors. I analyzed studies of the associations between alachlor and glyphosate exposure and cancer incidence, both derived from the Agricultural Health Study cohort, to quantify the bias and unce...

Dielectric properties of materials are defined, and the major factors that influence these properties of agricultural and food materials, namely, frequency of the applied radiofrequency or microwave electric fields, and water content, temperature, and density of the materials, are discussed on the basis of fundamental concepts. The dependence of measured dielectric properties on these factors i...
