Pathways 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...
متن کاملConservation in the optimal use of rangelands
In previous papers we have considered the optimal mix of biodiversity in semi-arid rangelands, focusing on the steady state. This paper addresses the question of conservation in the optimal use of rangelands, where conservation is understood to mean maintenance of the system in a ‘natural’ state. We consider a rangeland that may exist in one of two states. In the ‘natural’ state, its dynamics a...
متن کاملBush 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 ...
متن کاملDrought, change and resilience in South Africa’s arid and semi-arid rangelands
Introduction Droughts are a frequent occurrence in South Africa’s arid and semi-arid rangelands and can have severe ecological and economic consequences. While these may be short-term and followed by recovery during subsequent years of higher rainfall, in some cases droughts can trigger substantial and irreversible ecological and socio-economic changes. Desertification, in the form of reduced p...
