The Grasshopper Integrated Pest Management Project (GHIPM) WDS a S15 million projccllhat lasted from 1986 La 1994 to identify, develop, and implement rangeland grasshopper management tactics within the Framework of Integrated Pest Management (lPI\'I) in the western United Stales. Computer simulation has been used La fulfill many original objectives for GHIPM and help bridge the gap between theo...

since last decades, there has been a growing interest in the human/social dimensions of natural resources governance especially the structure of social networks in achieving to successful co-management of natural resources. network analysis as a suitable tool in optimum planning of the “network management” of rangeland in regional scale, can improve inter-organizational decision-making and coor...

There have been few attempts to develop, test or apply sustainability indicators for natural resource management at a farm-level, and even fewer have fully consulted land users from the initiation of this process. While environmental sustainability indicators need to be accurate and reliable, land users also need them to be rapid, cost-effective and easy to use, in addition to being linked to m...

Afforestation of marginal agricultural lands represents a promising option for carbon sequestration in terrestrial ecosystems. An ecosystem carbon model was used to generate new national maps of annual net primary production (NPP), one each for continuous land covers of ‘forest’, ‘crop’, and ‘rangeland’ over the entire U. S. continental area. Direct inputs of satellite “greenness” data from the...

Drought is common in rangeland environments and an understanding of its impacts on the structure and function of rangeland ecosystems is paramount for developing effective management strategies. This research was the second of a series of studies investigating the impacts of varying seasonal droughts on northern Great Plains rangelands. Research was conducted on native rangeland during the 1998...

Rangeland monitoring services require the capability to investigate vegetation condition and to assess biomass production, especially in areas where local livelihood depends on rangeland status. Remote sensing solutions are strongly recommended, where the systematic acquisition of field data is not feasible and does not guarantee properly describing the spatio-temporal dynamics of wide areas. R...

Rangelands are globally extensive, provide fundamental ecosystem services, and are tightly coupled human-ecological systems. Rangeland sustainability depends largely on the implementation and utilization of various grazing and burning practices optimized to protect against soil erosion and transport. In many cases, however, land management practices lead to increased soil erosion and sediment f...
