Accounting for lost acreage.

چکیده
Privately owned forests, wetlands, and crop-lands in the United States are disappearing at alarming rates due to development and erosion , according to a report released by the U.S. Department of Agriculture (USDA) on 7 December 1999. The report, which summarizes the USDA's 1997 National Resources Inventory (NRI), reveals that development has doubled during the last decade to-more than three million Consarvatio acres a year. In announcing the report in an Cropland: 375.0-_ address to the USDA's National Conservation Summit at Iowa State University, agricultural secretary Dan Glickman Fderal: said, `Conservation chal-22 lenges are mounting and Dwloped: 105A4 intensifying more quickly N~Rouceskn.b than we are solving them." Glickman urged Americans to join in a collaborative effort to improve the declining health of America's private land, which accounts for about 75% of total land cover. The NRI, which is conducted every five years (1997 is the latest), is a statistical analysis based survey of nonfederal land. It comprises data on land use, soil erosion, farmland and wetland loss, and other natural resource information from 800,000 selected locations in the United States. Conversion of agricultural land to other purposes such as subdivisions and industrial areas is traditionally thought of as happening only around major metropolitan areas. The NRI report shows that growing numbers of small and mid-sized cities are also contributing to land loss. According to the NRI, states with the highest acreage conversion rates and Texas. In a 6 December 1999 statement, Vice President Al Gore said that the high agricultural conversion rates do not threaten American's food supply but do result in land fragmentation and loss of family farms that raise produce for urban markets, as well as elimination of open spaces. "It's shocking to see to what extent states have experienced rapid conversion from farmland," says Don Buckloh, a farmland information specialist with the American Farmland Trust (AFT), a nonprofit organization that works to prevent productive farmland loss and aims to keep private land in private hands. The AFT uses the NRI to dosely analyze agricultural conversion in each state and to develop condusions about the most threatened farmland areas. In past years, the AFT published its analysis of the NRI in a report called Farming on the Edge. Currendy, the AFT is updating its publication with the new information released in the 1997 NRI report. Buckloh says that the Farming on the Edge reports take the resource information …

Forecasting food production is important to identify possible shortages in supply and, thus, food security risks. Such forecasts may improve input allocation decisions that affect agribusiness and the input supply industry. This paper explains methods and data used to forecast acreage of four crops that are particularly important staple commodities in the world, namely wheat, corn, rice, and so...

Prior to the 2000 planting season, some industry obsemers predicted acreage of genetically modified crops would decline dramatically. However, actual 2000 plantings presented a puzzle. Farmers reduced their acreage of genetically modified corn, but concurrently increased their acreage of genetically modified soybeans. We demonstrate that it may be theoretically optimal for risk-averse farmers t...

∗ Corresponding author: WU Quan, senior engineer, CAAE, mobile phone:+8613621043045 Abstract: Grain production is of great importance to any country, especially to China. It is very important for local and central governments to get accurate main crops acreage information in time. One noticeable problem is that the estimated accuracy for crops acreage in a certain year is not high, so that Remo...
