Food, Inc. is a 2008 American documentary film directed by Emmy Award-winning filmmaker Robert Kenner.[2] The film examines large-scale agricultural food production in the United States, concluding that the meat and vegetables produced by this type of economic enterprise have many hidden costs and are unhealthy and environmentally-harmful. The film is narrated by Michael Pollan and Eric Schlosser, two long-time critics of the industrial production of food.[3][4] The documentary generated extensive controversy in that it was heavily criticized by large American corporations engaged in industrial food production.[2]

The new tool is based on computer-based geographical information systems (GIS) that collect, store, analyse and present geographical data. This means that the tool describes real roofs in the correct surroundings. The sun in the model illuminates the three-dimensional built environment and simulates how surrounding buildings, terrain and vegetation throw shadows.

Solar-powered drip irrigation enhances food security in the Sudano–Sahel documents a field research project which found that: "solar-powered drip irrigation significantly augments both household income and nutritional intake, particularly during the dry season, and is cost effective compared to alternative technologies" Over the decades, irrigation has been shown to greatly increase agricultural productivity. Drip irrigation is spreading rapidly in Africa, with significant benefits. "Drip irrigation delivers water (and fertilizer) directly to the roots of plants, thereby improving soil moisture conditions; in some studies, this has resulted in yield gains of up to 100%, water savings of up to 40–80%, and associated fertilizer, pesticide, and labor savings over conventional irrigation systems" The solar-powered systems, however, look to offer the potential for even better results. From the study on impacts of PVDI systems it was reported: "The women’s agricultural group members utilizing the PVDI systems became strong net producers in vegetables with extra income earned from sales, significantly increasing their purchases of staples, pulses, and protein during the dry season, and oil during the rainy season. Finally, survey respondents were asked how frequently they were unable to meet their household food needs. Based on the frequency and most recent incident, households were assigned a food insecurity score ranging from zero (no problems during the previous year) to one (perpetually unable to meet food needs). This score changed significantly for project beneficiaries, as they were 17% less likely to feel chronically food-insecure. In short, the PVDI systems had a remarkable effect on both year-round and seasonal food access."

Several weeks ago, a group of researchers published an article in the Proceedings of the National Academy of Sciences documenting how relatively low-powered solar systems offer the potential to increase food supplies in impoverished arid regions while reducing demands for fertilizers and other costly (in fiscal and other terms) additives.
