 Pastoralism has become a contemporary anthropological and ecological study as it faces many threats including fragmentation of land, conversion of rangeland into urban development, lack of grazing movement, impending threats on global diversity, damage to species with large terrain, decreases in shared public goods, decreased biological movements, threats of a "tragedy of enclosures", limitation of key resources, reduced biomass and invasive plant species growth.Interest in contemporary pastoralist cultures like the Maasai has continued to increase, especially because the traditional syncreticly-adaptive ability of pastoralists could promise lessons in collaborative and adaptive management for contemporary pastoralist societies threatened by globalization as well as for contemporary non-pastoralist societies that are managing livestock on rangelands.In the United States, the study of range science is commonly offered at land-grant universities including New Mexico State University, Colorado State University, Oregon State University, North Dakota State University, South Dakota State University, Texas A&M University, Texas Tech University, the University of Arizona, the University of Idaho, the University of Wyoming, Utah State University, and Montana State University.
