| We investigate the relationships between water quality and socioeconomic factors in California at the county level for the years 1993 to 2006 using 24 water quality indicators coming from seven different types of water bodies. We estimate these relationships using three classes of models: the traditional per capita income-pollution level - Environmental Kuznets Curve (EKC) - specifications, a more inclusive model containing main socioeconomic variables such as agricultural intensity, land use, ethnic composition, population density and educational attainment, and a model that includes the socioeconomic variables while accounting for spatial correlations too. For most water quality indicators, we do not find support for EKC specifications. For pollutants... |

| During the 1990s, demand for organic products increased on average by 20% each year. This growth in demand fueled growth in organic crop acreage. Between 1992 and 2005, organic cropland more than quadrupled, going from 403,400 acres to just over 1.7 million acres (USDA, 2008). Demand is predicted to increase annually by an additional 9 to 16% through 2010 (Dimitri and Oberholtzer, 2005). This further increase in demand will lead to an additional expansion of organic acreage, increasing the heterogeneity of agricultural regions and increasing the interaction that occurs between conventional and organic farms as they more frequently share the same regional landscape. Sharing the same landscape implies that they share pest and natural enemy populations. The... |
