Shedding Light on the Global Distribution of Economic Activity

Abstract: Collection of data on economic variables, especially sub-national income levels, is problematic, due to various shortcomings in the data collection process. Additionally, the informal economy is often excluded from official statistics. Nighttime lights satellite imagery and the LandScan population grid provide an alternative means for measuring economic activity. We have developed a model for creating a disaggregated map of estimated total (formal plus informal) economic activity for countries and states of the world. Regression models were developed to calibrate the sum of lights to official measures of economic activity at the sub-national level for China, India, Mexico, and the United States and at the national level for other countries of the world, and subsequently unique coefficients were derived. Multiplying the unique coefficients with the sum of lights provided estimates of total economic activity, which were spatially distributed to generate a spatially disaggregated 1 km map of total economic activity.

Review of Satellite Remote Sensing Use in Forest Health Studies

Abstract: Satellite remote sensing has been used in forest health management as a method for vegetation mapping, fire fuel mapping, fire risk estimation, fire detection, post-fire severity mapping, insect infestation mapping, and relative water stress monitoring. This paper reviews the use of satellite remote sensing in forest health studies, including current research activities; the satellite sensors, methods, and parameters used; and their accuracy. The review concludes that the Moderate Resolution Imaging Spectroradiometer satellite data (MODIS) are more appropriate for most of the remote sensing applications for forest health than other current satellite data when considering temporal and spatial resolutions, cost, and bands. MODIS has a 1-2 day temporal and a 250-1000 m spatial resolution; the data are free and cover more spectral bands than other satellites (up to 36 bands). We recommend that physical and physiological modeling (e.g., evapotranspiration and biomass growth) be developed for remote sensing of forest health. Some additional satellite sensors, such as for high temperature estimates (as high as 1800 K) and sensors of narrow bands, are also needed.

Irish Chefs and Restaurants in the Geography of "Local" Food Value Chains

Abstract: Restaurant chefs and owners have a potentially influential role to play in promoting the use of local foods and supporting producers. Indeed chefs are taste makers, and their conceptualization of local food can influence consumers' perceptions, knowledge and geographical awareness. Yet their role is not well documented in research literature. In-depth interviews were conducted with seven purposively selected chefs in Galway City, Ireland, who are seeking to develop a local cuisine. Menus, websites, and statements of philosophy were also analyzed. Attention focused on the definition of local food, sources of supply, how local food is used in cuisine, and how it is presented on menus. Common themes among restaurants include the geographic stretching of local food to include artisan products, issues of seasonality and variability in supply, and questions about the authenticity of promoting the use of local foods. There are opportunities for building linkages between chefs and local producers, to promote authentic use of locally sourced foods. Recommendations are made for five strategies to build a sustainable local food geography, based on strengthening the farmer- to-chef shortened value chain.
