Ten principles for a landscape approach to reconciling agriculture, conservation, and other competing land uses

Abstract: “Landscape approaches” seek to provide tools and concepts for allocating and managing land to achieve social, economic, and environmental objectives in areas where agriculture, mining, and other productive land uses compete with environmental and biodiversity goals. Here we synthesize the current consensus on landscape approaches. This is based on published literature and a consensus-building process to define good practice and is validated by a survey of practitioners. We find the landscape approach has been refined in response to increasing societal concerns about environment and development tradeoffs. Notably, there has been a shift from conservation-orientated perspectives toward increasing integration of poverty alleviation goals. We provide 10 summary principles to support implementation of a landscape approach as it is currently interpreted. These principles emphasize adaptive management, stakeholder involvement, and multiple objectives. Various constraints are recognized, with institutional and governance concerns identified as the most severe obstacles to implementation. We discuss how these principles differ from more traditional sectoral and project-based approaches. Although no panacea, we see few alternatives that are likely to address landscape challenges more effectively than an approach circumscribed by the principles outlined here.

Childhood-onset versus adolescent-onset antisocial conduct problems in males: Natural history from ages 3 to 18 years

Abstract: We report data that support the distinction between childhood-onset and adolescent-onset type conduct problems. Natural histories are described from a representative birth cohort of 457 males studied longitudinally from age 3 to 18 years. Childhood- and adolescent-onset cases differed on temperament as early as age 3 years, but almost half of childhood-onset cases did not become seriously delinquent. Type comparisons were consistent with our contention that males whose antisocial behavior follows a life-course-persistent path differ from males who follow an adolescence-limited path. As adolescents, the two types differed on convictions for violent crime, personality profiles, school leaving, and bonds to family. These differences can be attributed to developmental history because the two groups were well matched on measures of antisocial conduct at age 18 years: parent-reports, self-reports, and adjudication records. By age 18 years, many conduct-problem boys had encountered factors that could ensnare them in an antisocial future: substance dependence, unsafe sex, dangerous driving habits, delinquent friends, delinquent perceptions, and unemployment. Implications for theory, research design, prevention, and therapeutic treatment of conduct problems are highlighted.

Global prevalence of anxiety disorders: a systematic review and meta-regression

Abstract: BackgroundThe literature describing the global prevalence of anxiety disorders is highly variable. A systematic review and meta-regression were undertaken to estimate the prevalence of anxiety disorders and to identify factors that may influence these estimates. The findings will inform the new Global Burden of Disease study.MethodA systematic review identified prevalence studies of anxiety disorders published between 1980 and 2009. Electronic databases, reference lists, review articles and monographs were searched and experts then contacted to identify missing studies. Substantive and methodological factors associated with inter-study variability were identified through meta-regression analyses and the global prevalence of anxiety disorders was calculated adjusting for study methodology.ResultsThe prevalence of anxiety disorders was obtained from 87 studies across 44 countries. Estimates of current prevalence ranged between 0.9% and 28.3% and past-year prevalence between 2.4% and 29.8%. Substantive factors including gender, age, culture, conflict and economic status, and urbanicity accounted for the greatest proportion of variability. Methodological factors in the final multivariate model (prevalence period, number of disorders and diagnostic instrument) explained an additional 13% of variance between studies. The global current prevalence of anxiety disorders adjusted for methodological differences was 7.3% (4.8–10.9%) and ranged from 5.3% (3.5–8.1%) in African cultures to 10.4% (7.0–15.5%) in Euro/Anglo cultures.ConclusionsAnxiety disorders are common and the substantive and methodological factors identified here explain much of the variability in prevalence estimates. Specific attention should be paid to cultural differences in responses to survey instruments for anxiety disorders.
