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...

In practice, questions of ecological company policy deal much more with technical questions than with organisational ones. In many guides for the implementation of an Environmental Management System the development of the organisation that first has to grow into this new task has not yet been...

The reductionist trend of equalizing sustainable development with CO2control needs to be reversed - notwithstanding the significance of climate change. Conventional, 'compartmentalized' data systems impede an integrated vision andtreatment of the paradigm. New accounts and balances focus on the...

Economists have expended considerable effort to develop economically meaningful definitions of the somewhat elusive concept of “sustainability.” We relate such a definition of sustainability to well known concepts from neoclassical economics, in particular, potential Pareto improvements (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...

This paper examines the theoretical foundations of Green National Accounting, noting that their assumptions have led to green national income measuring welfare-based income, which is not necessarily equal to sustainable income. We review two major approaches to estimating green accounting: the...

This paper first describes two types of adjustments to National Accounting Systems, which take the environment into account: the first type centres on accounting conventions, through a change in the system boundary, in order to include specified categories of environmental assets (called...

Within this paper, we analyse the fulfilment of the Kyoto-emissions reduction com-mitment exemplary in Germany and its implication on long-term paths of all macro-variables. Germany, like all other industrial or Annex B coun-tries, has to reduce its emissions by 2010 and after what we call a...

This paper discusses environmental policies which aim at a sustainable use of domestic resources which are mobile. It assumes that one country introduces such a policy but the other country does not. If a resource is mobile, strict domestic environmental policies may increase the resource...

Discounted utilitarianism treats generations unequally and leads to seemingly unappealing consequences in some models of economic growth. Instead, this paper presents and applies sustainable discounted utilitarianism (SDU). SDU respects the interests of future generations and resolves...
