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...

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...
