The agricultural policies shift gradually from EU-level organised market interventions to local organised environmental policies. This paper explores the growth possibilities of the Flemish dairy sector with the outlook of a quota abolishment as a case study of this policy shift. The dairy quota policy seems very restrictive for the highly profitable Flemish dairy sector, but the environmental restrictions from the manure regulation can limit the growth of the dairy sector as well. The paper uses a spatial multi-agent simulation model applied to a sample of 40.000 farms to estimate price development of emission rights and their possible impact on the growth of the dairy production. The results show that a higher milk production leads to higher prices for...

Derogation on the EU Nitrates Directive: does it make a difference?
Provedor de dados: 31
Autores: Claeys,   Dakerlia; Lauwers,   Ludwig H.; Marchand,   Fleur L.; Van Meensel,   Jef; Buysse,   Jeroen; Van der Straeten,   Bart; Van Huylenbroeck,   Guido.
The paper discusses an ex ante evaluation of the derogation on the Nitrates Directive for Flanders, Belgium, which is a case of intensive but highly productive livestock areas. The aim is to develop an accurate simulation model to detect small differences in manure surpluses caused by changes of manure production and/or utilization. The system of models consists of various modules to fine tune the calculations of manure production, fertilizing behaviour and manure allocation and disposal on and off farm. The results show that derogation may cause the existing manure surpluses to expire, if only nitrogen limits are considered and no transactions costs are taken into account. When also phosphate fertilization limits are considered, the increase in manuring...

Optimisation of policy interventions in environmental quota
Provedor de dados: 31
Autores: Buysse,   Jeroen; Van der Straeten,   Bart; Nolte,   Stephan; Claeys,   Dakerlia; Lauwers,   Ludwig H.; Van Huylenbroeck,   Guido.
The paper analyses the governance choices in production quota with the Flemish nutrient production rights as a case. A static model of quota trade in the short run shows the inefficiency of discrete non-auctioned trade with fixed transaction costs. This model also shows that an obligation to quota sellers to stop their production stimulates structural change. A dynamic model of trade indicates that the measures taken to prevent speculative behaviour causes inefficiencies and stimulates overuse of quota if the penalties are too low. Finally, the dynamic model indicates that a flat rate reduction on traded quota combined with too low penalties for overuse stimulate the total production.

Cost-benefit analysis of abatement measures for nutrient emission from agriculture
Provedor de dados: 31
Autores: Wustenberghs,   H.; Broekx,   Steven; Van Hoof,   K.; Claeys,   Dakerlia; D'Heygere,   T.; D'Hooghe,   J.; Dessers,   R.; Huysmans,   T.; Lauwers,   Ludwig H.; Meynaerts,   E.; Vercaemst,   P.
In intensive animal husbandry areas surface water N and P concentrations often remain too high. The Water Framework Directive calls for additional nutrient emission abatement measures. Therefore, costs and benefits for possible agricultural measures in Flanders were first analysed in terms of soil balance surplus. Finally, abatement measures for agriculture, households and industry were set off against each other and ranked according to their cost-efficiency by the Environmental Costing Model. Increased dairy cattle efficiency, winter cover crops and increased pig feed efficiency turn out very cost efficient. Other agricultural measures are less cost efficient than for instance collective treatment for households and industry.

Flexible quota constraints in positive mathematical programming models
Provedor de dados: 31
Autores: Buysse,   Jeroen; Van der Straeten,   Bart; Claeys,   Dakerlia; Lauwers,   Ludwig H.; Marchand,   Fleur L.; Van Huylenbroeck,   Guido.
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...

The effect of EU derogation strategies on the complying costs of the nitrate directive
Provedor de dados: 31
Autores: Van der Straeten,   Bart; Buysse,   Jeroen; Nolte,   Stephan; Lauwers,   Ludwig H.; Claeys,   Dakerlia; Van Huylenbroeck,   Guido.
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...

Effects of a flat rate introduction: shifts in farm activity and impact on farmers' income
Provedor de dados: 31
Autores: Marchand,   Fleur L.; Buysse,   Jeroen; Campens,   V.; Claeys,   Dakerlia; Fernagut,   Bruno; Lauwers,   Ludwig H.; Van der Straeten,   Bart; Van Huylenbroeck,   Guido.
Current thoughts on CAP changes, e.g. the "Health Check", emphasize the necessity to move away from payments based on historical receipts towards a "flatter rate" system. The aim of current research is to simulate the impact of a flat rate system (equal payments per hectare of cultivated land) compared to the current historical system (payments based on individual historic entitlements). Impact on production and income of arable, dairy and cattle farms of two different flat rate scenario's, is assessed with a farm-based sector model for Flanders. The model maximizes income at farm level, calibrated to observed farming behavior in 2001-2003. Farm data can be selected by farm type, size and region, simulations could be run for specific sub sectors, size...

Modelling the effects of an abolition of the EU sugar quota on internal prices, production and imports
Provedor de dados: 31
Autores: Nolte,   Stephan; Buysse,   Jeroen; Van der Straeten,   Bart; Claeys,   Dakerlia; Lauwers,   Ludwig H.; Van Huylenbroeck,   Guido.
We apply a spatial price equilibrium model of the world sugar market to simulate an abolishment of the EU quota system in 2015/16. To overcome the normative nature of the approach, we calibrate the model by attaching a non-linear cost term to each trade flow. This is in some regards similar to positive mathematical programming. We suggest an economic interpretation and an econometric specification of the cost term. Production in the EU increases to almost 16 million tons. Twelve member states increase production, seven reduce it. Preferential imports are significantly reduced. Simulated effects are found to be more pronounced the higher the world market price.

The sampling bias in multi-agent simulation models
Provedor de dados: 31
Autores: Buysse,   Jeroen; Frija,   Aymen; Van der Straeten,   Bart; Nolte,   Stephan; Lauwers,   Ludwig H.; Claeys,   Dakerlia; Van Huylenbroeck,   Guido.
For practical considerations, it is in some case impossible to simulate MAS models at population level. The current paper shows that MAS models applied to samples with heterogeneous costs of interactions between agents have biased results. Heterogeneous costs of interactions in MAS models can come from the spatial dimension in MAS models or from fixed costs per interaction. The paper presents two correction procedures to remove the sampling bias and to increase the reliability of the outcome. The correction procedures can be very promising for future applications of MAS models because it becomes possible to deploy more complex models without bias on more detailed datasets that are only available at sample level, which will be the case for country- or...

Fertilization: trade-offs between manure abatement and plant productivity
Provedor de dados: 31
Autores: Van der Straeten,   Bart; Buysse,   Jeroen; Marchand,   Fleur L.; Lauwers,   Ludwig H.; Claeys,   Dakerlia; Van Huylenbroeck,   Guido.
In 2005, 30% of the Flemish farms faced a manure excess, while at aggregated level still 9.7% of the emission rights were unused. This means that, despite the various possibilities, Flemish farmers do not succeed in an effective exchange of manure between farms. In current paper is shown how inorganic fertilizer use influences the use and exchange of organic nitrogen. Because of the mutual interdependency between organic and inorganic nitrogen emission rights (or quota), inorganic nitrogen use limits the emission rights for organic nitrogen. Utilisation of these emission rights are analysed as a trade-offs choice between plant productivity (use of inorganic nitrogen) and manure disposal, as the major abatement alternative of manure production. Farmers...
