The North American nice Plains is an immense international breadbasket yet its agriculture is under pressure by way of drought, warmth, destructive winds, soil erosion and declining floor water assets. Biomass creation and processing at the Plains could partly restoration a perennial vegetative disguise and create employment possibilities. This e-book explores the prospect that the ecology and economic climate of the Plains sector, and comparable areas, would receive advantages from the advent of perennial biomass crops.

The measure of dependence on hydroelectricity is the ratio of electricity supplied by hydroelectric facilities to the total basin electricity production. 25) indicates a high dependence on hydroelectricity which, in the case of the Great Plains region, applies only to the Missouri River basin. • The measure of groundwater vulnerability is the ratio of annual groundwater overdraft to total groundwater withdrawals. 25 already have groundwater supply problems. All of the Great Plains MWRRs but the Souris-Red-Rainey are vulnerable on this score.
Table 2-1 shows how ET from a standard water-filled pan at a Great Plains location differs from that in other climatic regions of the USA. Coshocton in central Ohio represents the humid Midwest; Davis lies in the Central Valley of California near Sacramento; Phoenix in central Arizona represents a desert climate; Mead lies between Lincoln and Omaha in eastern Nebraska—a region of more moderate climate than most of the Great Plains but nonetheless typical of its hydrologic regime. May to October account for between 75 and 81% of the average annual pan evaporation at all four locations.
Which are the analogous regions, if any, for the NAGP? ” Nuttonson’s work (1955, 1965, 1966) which provided detailed climatological comparisons of growing regions for wheat and other major crops remains authoritative today. Wheat is grown widely throughout the world. In one study of climatic requirements for wheat production Nuttonson (1966, Table 1, p. 9) found that yearround climates of the Northern Plains from Langdon, North Dakota at 48°55′N to Dodge City, Kansas at 37°45′N are closely mimicked in their annual, warmest month and coldest month maximum, minimum, and mean temperatures, in annual relative humidity and in annual precipitation and its seasonal distributions at locations ranging from western Siberia, central Asia to the Lower Volga region of Russia, the Ukraine, and Turkey.
