We re-investigate evidence for the non-equilibrium concept for rangelands using a georeferenced data base of N =83 studies published in peer-reviewed journals. Following up on a previous study by von Wehrden et al. (2012), we use their global map of rainfall variability and their method to...

Strong sustainability, according to the common definition, requires that different natural and economic capital stocks have to be maintained as physical quantities separately. Yet, in a world of uncertainty this cannot be guaranteed. To therefore define strong sustainability under uncertainty in...

We analyze a dynamic and stochastic ecological-economic model of grazing management in semi-arid range lands. The non-equilibrium ecosystem is driven by stochastic precipitation. A risk averse farmer chooses a grazing management strategy under uncertainty such as to maximize expected utility...

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...

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 semiarid rangelands. In particular, we study debushing as an instrument of risk management that complements the choice of an adaptive grazing...

We study risk preferences and their determinants for commercial cattle farmers in Namibia who are subject to high and heterogeneous precipitation risk, using data from questionnaire and field experiments, simulated data for on-farm precipitation risk and data on famers' previous place of...

We empirically study personal norms of sustainability, conceptualized according to the normactivation theory and operationalized under the notion of strong ecological-economic sustainability, for commercial cattle farmers in semi-arid rangelands of Namibia, a system that is subject to extensive...

We study risk preferences and their determinants for commercial cattle farmers in Namibia who are subject to high precipitation risk that is heterogeneous across farms. We use data on risk preferences from questionnaire and field experiments, simulated data for on-farm precipitation risk and...

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...
