Bush encroachment control and risk management in semi-arid rangelands

Lukomska, Natalia; Quaas, Martin F.; Baumgärtner, Stefan - 2010

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...

Pitfalls and Potential of Institutional Change : Rain-Index Insurance and the Sustainability of Rangeland Management

Müller, Birgit; Quaas, Martin F.; Frank, Karin; … - 2011

Rain-index insurance is strongly advocated in many parts of the developing world to help farmers coping with climatic risk that prevails in (semi-)arid rangelands due to low and highly uncertain rainfall. We present a modeling analysis of how the availability of rain-index insurance affects the...

Characterizing Commercial Cattle Farms in Namibia : Risk, Management and Sustainability

Olbrich, Roland; Quaas, Martin F.; Baumgärtner, Stefan - 2014

Commercial cattle farming in semi-arid regions is subject to high rainfall risk. At the same time, it is prone to rangeland degradation. Theoretical works suggest that rainfall risk management by means of financial instruments may stabilize farming-derived income over the short-term, but...

Optimal grazing management rules in semi-arid rangelands with uncertain rainfall

Quaas, Martin F.; Baumgärtner, Stefan - 2011

We study optimal adaptive grazing management under uncertain rainfall in a discrete-time model. As in each year actual rainfall can be observed during the short rainy season, and grazing management can be adapted accordingly for the growing season, the closed-loop solution of the stochastic...
