The North American nice Plains is an incredible international breadbasket yet its agriculture is under pressure via drought, warmth, destructive winds, soil erosion and declining flooring water assets. Biomass creation and processing at the Plains might in part fix a perennial vegetative hide and create employment possibilities. This e-book explores the chance that the ecology and economic climate of the Plains quarter, and comparable areas, would get advantages from the advent of perennial biomass crops.

Sample text

By comparison with these mountain states Kansas, Nebraska, and the Dakotas are virtually treeless. 5 million hectares. Land area in crops is on the order of nearly 68 million hectares. North Dakota is the most heavily farmed of the Great Plains States with 64% of its area in crops, followed by Kansas, Nebraska, and South Dakota. Pasture and rangeland predominate in North Mexico, Texas and Oklahoma with more than 60% of the land in these three states in pasture or range. The mountain states of Montana and Wyoming and the Plains states of Nebraska and South Dakota are each more than 40% in range and pasture land (Table 2-4).

Evaporation greatly exceeds precipitation in this region. Vegetation in this province is dominated by arid grasslands on which shrubs and low trees grow singly or in bunches. Xerophytic blue grama and buffalo grasses dominate the plains of northwestern Texas and eastern New Mexico but mesquite grows in open stands among the grasses. Oak and juniper are mixed with The Physical Environment 35 grasses, especially needle grass, and mesquite on the Edwards Plateau. Soils in the region include Entisols and support mesquite-live oak savannah; Mollisols associated with mesquite–buffalo grass and juniper-oak savannah.

It is estimated that 185 km3 (150 million acre feet) had been withdrawn before 1950, when the major expansion of irrigation began in the region. Figure 2-8 also shows the change in water-level that occurred throughout the aquifer from predevelopment to 2003. The greatest declines, 15 to 46 m (50 to > 150 ft) have occurred in the Texas and Oklahoma Panhandles and in southwestern Kansas. In portions of Nebraska, south of the Platte River and at scattered locations in the east and central Nebraska, water levels have actually risen due to seepage from irrigation canals carrying river water originating in the Rocky Mountains.
