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...

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...

Transgenic crops, production risk, and agrobiodiversity
Vijesh, Krishna; Qaim, Matin; Zilberman, David - 2014
Do transgenic crops cause agrobiodiversity erosion? We hypothesize that they increase productivity and reduce production risk and may therefore reduce farmer demand for on-farm varietal diversity, especially when only a few transgenic varieties are available. We also hypothesize that varietal...
