| Modeling the farm level impact of risk management programs, policies and instruments is traditionally been done on a farm-level basis. Hence, farm simulation models typically use the behavioural assumption of profit or utility maximization is risk aversion taken into account. However, abundant – albeit indirect – evidence from different literature sources suggest that minimization of household risk – being the chance of falling below a certain threshold level of household cash flow – might be more realistic behavioural assumption. In this paper, we present concepts of operational, financial, total farm and household risk. Further, using a stochastic simulation model on two typical Belgian dairy farms, we illustrate possible farmers responses in the... |

| This paper presents the MicroWave approach that has been developed to improve the process of modeling in the context of micro simulation. It leads to a more efficient model development, better quality of models and their output and improvement in knowledge management. A conceptual framework has been developed and translated into a hierarchical structure of GAMS program code. Besides, several software applications and other tools have been developed for support. These products are presented and some examples illustrate how MicroWave can be applied. MicroWave is especially useful in interdisciplinary research in which different persons are involved in the modeling process and when different models have to be combined. |

| Agricultural policy makers aim to combine strong economic performance with a sustainable use of natural resources. An important step is to move from trying to define sustainability towards developing concrete tools for measuring and promoting achievements in sustainability. Hence, sustainability assessment is inevitably based on strong simplifications both of the theoretical paradigm and of the characteristics of systems of concern. The most known approaches to assess sustainability performance are burden orientated: they assess the costs or potential harm of resource use. These burden-oriented approaches focus on the level of environmental impacts caused by an economic activity compared to another set of environmental impacts, while value-oriented impact... |
