Bush encroachment control and risk management in semi-arid rangelands.
We study the role of bush encroachment control for a farmer's income and income risk in a stochastic ecological-economic model of grazing management in semi-arid rangelands. In particular, we study debushing as an instrument of risk management that complements the choice of an adaptive grazing management strategy for that sake. We show that debushing, while being a good practice for increasing ...

Desertification, in the form of reduced p...
متن کاملSoil-Vegetation Relationships in Arid Rangelands (Case Study: Nodushan Rangelands of Yazd, Iran)

Soil samples were taken in 0-10 and 10-80 cm layers. The species studied were Salsola tomentosa, Salsola arbuscula, Peganum harmala, Zygophylum eurypterum and Eurotia ceratoides. Canonical corres...
متن کاملPathways for positive cattle-wildlife interactions in semi-arid rangelands
Livestockwildlife interactions in rangelands are often viewed in terms of competition, but livestock and native ungulates can also benefit each other through longterm modifications of rangeland habitats. Here we synthesize research on rangelands in central Laikipia focusing on two types of cattlewildlife interactions that have implications for their longterm coexistence. The first interaction o...
