| The ecosystem and the economic subsystem are interlinked. In fact, it is the overconsumption of scarce resources or the overproduction of bad outputs at economic system level that causes a great part of the imbalances at the ecosystem level. Some imbalances do not originate at the economic system level, but are due to external factors. Given the possibility of external shocks, respecting static sustainability thresholds is not a guarantee for system sustainability. In a dynamic setting, the concept of resilience is therefore helpful. In this paper we show how this concept can complement the traditional efficiency approach to come to a sustainable value creating economic system. |

| 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... |

| institutions of sustainability (PIoS), which are sets of rules that a series of private actors voluntary follow to reach a sustainability target. Within PIoS, a strong position on sustainability themes is used as a mean to maximize private utility. Consequently, there is a potential win-win situation for both the private actors and the society. Typical for these multistakeholder PIoS is their hybrid configuration. Ménard (2004) introduced the concept of hybrids as an intermediate between pure anonymous spot markets and firms as hierarchies. It is a governance structure where actors have transferred part of their autonomous property rights to others, in order to allow for some coordination between partners. One of the main examples of PIoS in the food... |

| Within the framework of the nitrate directive, member states have the possibility to apply for derogation, i.e. increasing fertilization standards under certain conditions. Several EU regions have made use of this possibility but all in a different way. In 2009, 6 different derogation policies were worked out. This paper focuses on the differences between the applied policies and makes an assessment of the impact of these differences on the application rate of derogation, the manure surplus and the costs to allocate the manure. Based on the MP-MAS model described by Van der Straeten et al. (2010) the different scenarios are applied on a single case area (Flanders) and the economic effects have been simulated. Results show large differences between the... |

| Greenhouse horticulture can play a major role in Flemish rural development, regional economy and employment. However, the sector deals with structural problems. Scale increase of greenhouse firms is required for economic reasons, but high investments and risks make this quasi unsupportable for individual farmers. Clustering greenhouses into greenhouse parks is a possible way out. Through collaboration and mutual material exchanges, firms enjoy scale effects and eco-efficiency is enhanced without individual enlargement. The government is planning pilot projects to investigate possibilities of greenhouse parks in Flanders. Obviously, many obstacles are faced, such as spatial planning, coordination of policy levels and institutions and interactions with... |

| To explain over- and underuse of available quota, Buysse et al. (2007) have integrated the shadow cost of the quota constraint in a quota flexibility function in a positive mathematical programming model. This method and central hypothesis, formulated and tested for the case of Belgian sugar beet farms, is in current paper extended and confirmed for the cases of Flemish dairy quota and manure emission rights. Despite the different organisation, objectives and implementations of the diverse quota systems, the results are similar. A higher utilisation of quota is significantly driven by the quota rent, but farm characteristics are also important and the effect declines with increasing quota rent. Regardless the quota, the dairy quota flexibility behaviour of... |

| This poster aims at describing different groups of technology use within a farm population and at delivering realistic prognoses of their future status as input for sector modeling. This because sector models are in many cases not based on reasonable technological progress estimations or too simplified as normative estimation or seen as mere extrapolation of past evolutions. The classification and utilization of technology groups is done for livestock activities, but illustrated hereafter for the finishing pigs activities. The research is worked out in three phases: • Organizational aspects of tuning information demand and supply; • Identification of technology groups; • Evolution of technology groups. Following techniques are used to identify the... |

| A new method for analysing environmental efficiency, based on the materials balance, is proposed. With this method, an environmental allocative efficiency measure can be defined analogously to the more commonly used economic allocative efficiency. Nutrient surplus in pig fattening, a typical balance indicator, is used to illustrate the concept in a two input one output case. The materials balance based efficiency analysis is elaborated using data envelopment analysis (DEA). Results are compared with those of more common, merely input or output oriented DEA approaches. A main conclusion is that, ignoring the balance feature of environmental issues such as nutrient surplus might be a main reason why traditional integral analyses of economic and... |

| A farm model is developed for simulating the potential income change resulting from conversion to organic farming. The model uses conventional farm data, taken from the Belgian FADN. Given the normative character of the model, and the impossibility of calibration to historical conversion behaviour, two model variants, a rigid and a flexible, are created to broaden the analysis scope. Moreover, extra attention is paid to the verification process and sensitivity analysis. Results reveal that the economic potential for conversion is rather high, if farmers are willing to change their farm management sufficiently. Furthermore, conversion potential depends on the farm type and conventional farm characteristics. The model finally proves to be an interesting tool... |
