Journal of Soil and Water Conservation back issues from September 1996:
Expanding our views of international challenge. (Soil and Water Conservation Society)(Special Issue: Global Change & Terrestrial Ecosystems)
Sep 01, 1996; ... The Soil and Water Conservation Society is in its fifties. For most people, their fifties are a time to look back, make a note of accomplishments, complain about aches and pains that don't go away as fast as they should, look forward to grandchildren, look ahead in preparation for ...
Global change & terrestrial ecosystems.(Special Issue: Global Change & Terrestrial Ecosystems)(Editorial)
Sep 01, 1996 ... This issue of the Journal of Soil and Water Conservation contains a series of papers developed from an international workshop of the GCTE Soil Erosion Network on the theme of soil erosion under global change.One of the major threats for sustainable land management is soil erosion ....
The GCTE soil erosion network: a multi-participatory research program. (Global Change and Terrestrial Excosystems Core Project)(Special Issue: Global Change & Terrestrial Ecosystems)(Editorial)
Sep 01, 1996; ... One of the major threats for sustainable land management is soil erosion. Erosion is a major type of human-induced land degradation; while recognizing that an accurate figure is hard to establish, Oldeman et al. (1991) suggest that about one-sixth of the world's usable land has already been ...
Using soil erosion models for global change studies.(Special Issue: Global Change & Terrestrial Ecosystems)(Editorial)
Sep 01, 1996; ... Future changes in climate and atmospheric C[O.sub.2] concentration will change the hydrologic cycle, affecting important soil-plant-water interactions, which in turn affect soil erosion rates. Climate and C[O.sub.2] changes can be estimated with global circulation models (GCMs). Mathematical ...
Water erosion monitoring and experimentation for global change studies.(Special Issue: Global Change & Terrestrial Ecosystems)(Editorial)
Sep 01, 1996; ... Taking steps to preserve the quality and quantity of global soil resources should require no justification. Our future ability to feed ourselves and live in an unpolluted environment depends on our ability to reduce the rates at which our soils are currently eroding. The unprecedented ...
Scaling up processes and models from the field plot to the watershed and regional areas.(Special Issue: Global Change & Terrestrial Ecosystems)
Sep 01, 1996; ... Soil erosion phenomena occur at a range of time and space scales, from the plot in which individual measurements are made, via the field scale which concerns the individual farmer, up to national or regional scales where they can influence major planning decisions. A number of approaches to ...
The GCTE validation of soil erosion models for global change. (Global Climate and Terrestrial Ecosystems Core Project)(Special Issue: Global Change & Terrestrial Ecosystems)
Sep 01, 1996; ... Take a hammer! It may be used (or misused) to bang in nails and tacks, as a crowbar or lever, and for many other things. Now imagine that you are selecting a hammer for use in some odd job. You probably would not just grab whatever hammer happened to be closest to hand. Instead, you might ...
Wetlands potentially exempted and converted under proposed delineation changes.(Special Issue: Global Change & Terrestrial Ecosystems)
Sep 01, 1996; ... The federal government currently tries to balance the needs of wetland owners with the needs of the general public through two laws that restrict alteration of wetlands: Section 404 of the Clean Water Act, which requires permits for certain activities that affect wetlands; and the so-called ...
Long-term harmful effects of crested wheatgrass on Great Plains grassland ecosystems.(Special Issue: Global Change & Terrestrial Ecosystems)
Sep 01, 1996; ... Invasions by exotic plants are occurring at an increasing rate and are considered a serious threat to both agricultural systems as well as native communities (Drake et al. 1989). Many of the most harmful exotics in North America were introduced intentionally (Ruesink et al. 1995, Williams ...
Remote sensing clearcut areas within a forested watershed: comparing SPOT HRV panchromatic, SPOT HRV multispectral, and Landsat Thematic Mapper data. (Le Systeme Pour l'Observation de la Terre)(Special Issue: Global Change & Terrestrial Ecosystems)
Sep 01, 1996; ... The cumulative effects of clearcut harvesting and associated road construction can expose soil and cause major sedimentation problems within a forested watershed (Anderson and Potts 1987; Binkley and Brown 1993; Duncan et al. 1987; Strach 1990; Swanson and Dyrness 1975). To harvest timber in ...
A GIS procedure for automatically calculating the USLE LS factor on topographically complex landscape units. (geographic information systems; Universal Soil Loss Equation)(Special Issue: Global Change & Terrestrial Ecosystems)
Sep 01, 1996; ... Despite its shortcomings and limitations the Universal Soil Loss Equation (USLE) is still the most frequently used equation in (applied) erosion studies. This is mainly due to the simple, robust form of the equation as well as to its success in predicting the average, long-term erosion on ...
GIS: a tool for siting farm ponds. (geographic information systems)(Special Issue: Global Change & Terrestrial Ecosystems)
Sep 01, 1996; ... Research was undertaken to develop a methodology for using a geographic information system (GIS) to identify the best sites for livestock watering ponds, based on surface runoff hydrology. When rainfall patterns are unpredictable in both quantity and timeliness, the ability to successfully ...
Conserving water and increasing alfalfa production using a tall wheatgrass windbreak system.(Special Issue: Global Change & Terrestrial Ecosystems)
Sep 01, 1996; ... Black and Siddoway (1971) suggested that rows of tall wheatgrass [Thinopyrum ponticum (Podp.) Barkworth & D.R. Dewey, previously Agropyron elongatum (Host) Beauv.], perennial bunchgrass, offered an alternative to tree and shrub windbreaks commonly planted throughout the Great Plains and ...
