We model interhousehold transfers between nomadic livestock herders as the statedependent consequence of individuals’ strategic interdependence resulting from the existence of multiple, opposing externalities. A public good security externality among individuals sharing a social (e.g., ethnic) identity in a potentially hostile environment creates incentives to band together. Self-interested int...

~ Riparian lands are among the most productive ecosystems on earth. They occupy only a small proportion of the landscape but frequently support a greater variety and abundance of animal life than adjacent habitats. ~ Important habitat components include vegetation (often taller, denser, more diverse, and more complex in riparian lands), food, standing water, shelter from predators, sites for ne...

According to the nonequilibrium theory, livestock grazing has a limited effect on long-term vegetation productivity of semiarid rangelands, which is largely determined by rainfall. The communal lands in northeastern South Africa contain extensive degraded areas which have been mapped by the National Land Cover (NLC) program. Much evidence suggests that long-term heavy grazing is the cause of th...

Historical perspective of fire and grazing Human applications of fire to benefit grazing animals is not a new concept. Historical evidence indicates that aboriginal people in North America (Anderson 2006), Australia (Murphy and Bowman 2007), and Africa (Archibald et al. 2005) frequently burned rangelands and forested lands to attract wildlife, remove standing dead plant biomass, to stimulate ne...

Perennial grasslands, including prairie and pasture, have declined with tremendous environmental social costs. This decline reflects unequal policy support for grasslands managed grazing compared to row crops. To create a resource community partners decision-makers, we reviewed analyzed the tools implementation capacity that supports constrains in U.S. Upper Midwest. Risk reduction subsidies co...

Agriculture impacts both human welfare and biodiversity at the same time. Still, social ecological assessments have commonly analyzed relevance of agroecosystems separately. We evaluated avian feeding use biocultural landscape in Jardín, Colombia, using a socioecological approach. Together with farmers, we identified main units (i.e., fincas, grazing lands, town, forests) determined each unit t...
