Long-term investment to drive the adoption of precautionary, adaptive and resilience-building fisheries management measures is urgently required, especially given the financially difficult transition period to reach sustainable fisheries. In this paper a case for investing in the recovery of large marine ecosystems is provided based on the future value of recovered fish stocks. It is argued that the current market-based sustainable seafood movement alone will not affect the scale of change needed and must be complemented by investment in fundamental conservation measures that will lead to the recovery of marine ecosystems and promote long-term sustainable use. A rationale for addressing the economically challenging transition period is provided and the basis of a new financial institution to finance the measures necessary for realising the economic, social and environmental benefits of large-scale fisheries reform is proposed.  相似文献

Several spatial measures of community food access identifying so called “food deserts” have been developed based on geospatial information and commercially-available, secondary data listings of food retail outlets. It is not known how data inaccuracies influence the designation of Census tracts as areas of low access. This study replicated the U.S. Department of Agriculture Economic Research Service (USDA ERS) food desert measure and the Centers for Disease Control and Prevention (CDC) non-healthier food retail tract measure in two secondary data sources (InfoUSA and Dun & Bradstreet) and reference data from an eight-county field census covering 169 Census tracts in South Carolina. For the USDA ERS food deserts measure accuracy statistics for secondary data sources were 94% concordance, 50–65% sensitivity, and 60–64% positive predictive value (PPV). Based on the CDC non-healthier food retail tracts both secondary data demonstrated 88–91% concordance, 80–86% sensitivity and 78–82% PPV. While inaccuracies in secondary data sources used to identify low food access areas may be acceptable for large-scale surveillance, verification with field work is advisable for local community efforts aimed at identifying and improving food access.  相似文献
