    Land Resources for Crop Production

    About 35 million acres not being cultivated have high potential for crop use and 117 million more have medium potential, according to the 1982 National Resources Inventory (NRI) conducted by the U.S. Department of Agriculture. Converted high potential land would increase cropland area by 8 percent over the 421 million cropland acres inventoried in 1982. The cropland base would increase 36 percent if both high and medium potential land were converted, but soil erosion could increase by just over 1 billion tons annually, nearly 20 percent above 1982. If only high potential lands were converted, the erosion increase could be only about 4 percent. Less favorable cost/price relationships for crop production since 1982, several provisions in the 1985 farm act, and change in the U.S. tax code will all tend to discourage conversions

    Background: Criminal justice system involvement has been associated with health issues, including sexually transmitted disease. Both incarceration and sexually transmitted disease share associations with various social conditions, including poverty, stigma, and drug use. Methods: United States state laws (including Washington, D.C.) regarding drug possession and consequences of drug-related criminal convictions were collected and coded. Drug possession policies focused on mandatory sentences for possession of marijuana, crack cocaine and methamphetamines. Consequences of drug-related convictions included ineligibility for public programmes, ineligibility for occupational licences and whether employers may ask prospective employees about criminal history. We analysed correlations between state sexually transmitted disease rates and percentage of a state's population convicted of a felony. Results: First-time possession of marijuana results in mandatory incarceration in one state; first-time possession of crack cocaine or methamphetamines results in mandatory incarceration in 12 (23.5%) states. Many states provide enhanced punishment upon a third possession conviction. A felony drug conviction results in mandatory ineligibility for the Supplemental Nutrition Assistance Program and/or Temporary Assistance for Needy Families in 17 (33.3%) states. Nine (17.6%) states prohibit criminal history questions on job applications. Criminal convictions limit eligibility for various professional licences in all states. State chlamydia, gonorrhoea and syphilis rates were positively associated with the percentage of the state population convicted of a felony ( p &lt; 0.05). Conclusion: While associations between crime, poverty, stigma and health have been investigated, our findings could be used to investigate the relationship between the likelihood of criminal justice system interactions, their consequences and public health outcomes including sexually transmitted disease risk. </jats:sec
