"Global Food Security Support Analysis Data (GFSAD) at Nominal 1 km (GCAD) Derived from Remote Sensing in Support of Food Security in the Twenty-First Century: Current Achievements and Future Possibilities"^^ . "The precise estimation of the global agricultural cropland—\r\nextents, areas, geographic locations, crop types, cropping\r\nintensities, and their watering methods (irrigated or rain-fed;\r\ntype of irrigation)—provides a critical scientific basis for the\r\ndevelopment of water and food security policies (Thenkabail\r\net al., 2010, 2011, 2012). By year 2100, the global human population\r\nis expected to grow to 10.4 billion under median fertility\r\nvariants or higher under constant or higher fertility\r\nvariants (Table 6.1) with over three-quarters living in developing\r\ncountries and in regions that already lack the capacity\r\nto produce enough food. With current agricultural practices,\r\nthe increased demand for food and nutrition would require\r\nabout 2 billion hectares of additional cropland, about twice\r\nthe equivalent to the land area of the United States, and lead to\r\nsignificant increases in greenhouse gas productions associated\r\nwith agricultural practices and activities (Tillman et al., 2011).\r\nFor example, during 1960–2010, world population more than\r\ndoubled from 3 to 7 billion. The nutritional demand of the\r\npopulation also grew swiftly during this period from an average\r\nof about 2000 calories per day per person in 1960 to nearly\r\n3000 calories per day per person in 2010. The food demand of\r\nincreased population along with increased nutritional demand\r\nduring this period was met by the “green revolution,” which\r\nmore than tripled the food production, even though croplands\r\ndecreased from about 0.43 ha per capita to 0.26 ha per capita\r\n(FAO, 2009). The increase in food production during the\r\ngreen revolution was the result of factors such as: (1) expansion\r\nof irrigated croplands, which had increased in 2000 from\r\n130 Mha in the 1960s to between 278 Mha (Siebert et al., 2006)\r\nand 467 Mha (Thenkabail et al., 2009a,b,c), with the larger estimate\r\ndue to consideration of cropping intensity; (2) increase in\r\nyield and per capita production of food (e.g., cereal production\r\nfrom 280 to 380 kg/person and meat from 22 to 34 kg/person\r\n(McIntyre, 2008); (3) new cultivar types (e.g., hybrid varieties\r\nof wheat and rice, biotechnology); and (4) modern agronomic\r\nand crop management practices (e.g., fertilizers, herbicide,\r\npesticide applications)..."^^ .
