We clarify the definition and interpretation of “sustainability economics” (Baumgärtner and Quaas 2010) in response to recent comments by van den Bergh (2010), Bartelmus (2010) and others. For that sake, we distinguish between general and specific definitions of sustainability and...

We study how human preferences affect the resilience of economies that depend on more than one type of natural resources. In particular, we analyze whether the degree of substitutability of natural resources in consumer needs may give rise to multiple steady states and path dependence even when...

We empirically study personal norms of sustainability, conceptualized according to the norm-activation 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...

We argue that economics – as the scientific method of analyzing trade-offs – can be helpful (and may even be indispensable) for assessing the trade-off between intergenerational and intragenerational justice. Economic analysis can delineate the “opportunity set” of politics with respect...

We propose a formal description of individual preferences that captures a subsistence requirement in consumption in an otherwise standard constant-elasticity-ofsubstitution (CES) utility specification. We study how substitutability between the subsistence good and another good depends on the...

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...

Commercial cattle farming in Namibia, a prime example of livestock farming in semi-arid rangelands, is subject to a variety of risks, predominant among which is precipitation risk. At the same time it suffers from rangeland degradation that is at least partly due to inadequate management. We...

Resilience as a descriptive concept gives insight into the dynamic properties of a system. Sustainability as a normative concept captures basic ideas of inter- and intragenerational justice. In this paper we specify the relationship between resilience and sustainable development. Based on an...

Rain-index insurance is strongly advocated in many parts of the developing world to help farmers to cope with climatic risk that prevail 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...
