The Soil and Water Assessment Tool (SWAT) model is a continuation of nearly 30 years of modeling efforts conducted by the USDA Agricultural Research Service (ARS). SWAT has gained international acceptance as a robust interdisciplinary watershed modeling tool as evidenced by international SWAT conferences, hundreds of SWAT-related papers presented at numerous other scientific meetings, and dozens of articles published in peer-reviewed journals. The model has also been adopted as part of the U.S. Environmental Protection Agency (USEPA) Better Assessment Science Integrating Point and Nonpoint Sources (BASINS) software package and is being used by many U.S. federal and state agencies, including the USDA within the Conservation Effects Assessment Project (CEAP). At present, over 250 peer-reviewed published articles have been identified that report SWAT applications, reviews of SWAT components, or other research that includes SWAT. Many of these peer-reviewed articles are summarized here according to relevant application categories such as streamflow calibration and related hydrologic analyses, climate change impacts on hydrology, pollutant load assessments, comparisons with other models, and sensitivity analyses and calibration techniques. Strengths and weaknesses of the model are presented, and recommended research needs for SWAT are also provided.

The Agricultural Model Intercomparison and Improvement Project (AgMIP): Protocols and Pilot Studies

This wide-ranging and accessible contribution to the study of risk, ecology and environment helps us to understand the politics of ecology and the place of social theory in making sense of environmental issues. The book provides insights into the complex dynamics of change in `risk societies'.

Regulating nonpoint-source pollution from agriculture: An integrated modelling analysis

In this paper, a gravity model approach was employed to analyze the main factors influencing Egypt’s agricultural exports to its major trading partners for the period 1994 to 2008. Our findings are that a one percent increase in Egypt’s GDP results in roughly a 5.42 percent increase in Egypt’s agricultural export flows. In contrast, the increase in Egypt’s GDP per capita causes exports to decrease, which is attributed to the fact that an increase in economic growth, besides the increasing population, raises the demand per capita for all normal goods. Hence, domestic growth per se leads to reduced exports. The exchange volatility has a significant positive coefficient, indicating that depreciation in Egyptian Pound against the currencies of its partners stimulates agricultural exports. Transportation costs, proxied by distance, are found to have a negative influence on agricultural exports. These results are important for trade policy formulation to promote Egyptian agricultural exports to the world market.
