A FARM LEVEL ANALYSIS OF THE RELATION BETWEEN CAP REFORMS AND LOCAL ENVIRONMENTAL LEGISLATIONS: HOW AND IN WHICH EXTENT FLEMISH DAIRY FARMERS CAN FILL UP EXTRA MILK QUOTA? AgEcon
Van der Straeten, Bart; Buysse, Jeroen; Nolte, Stephan; Marchand, Fleur L.; Lauwers, Ludwig H.; Claeys, Dakerlia; Van Huylenbroeck, Guido.
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...

Alternative Territorial Breakdowns of Statistics for Supporting Rural Policies AgEcon
Lauwers, Ludwig H.; Kerselaers, Eva; Lenders, Sonia; Vervaet, Mieke; Vervloet, Dirk.
In order to support rural policy making with appropriate information, alternative territorial breakdowns of statistics are necessary. This paper shows how the widely used criterion of 150 inhabitants per km² can be fine tuned to better account for local specific conditions, in particular high population densities. Alternative population density thresholds are confronted with local perceptions of rurality, aggregated in a rurality index. The method is illustrated for two regions that differ in urbanisation level. The rurality index not only increases the discriminatory power, but also helps to find a less erroneous and more robust proxy for international comparable breakdowns of statistics.

An (in)efficiency based measurement of economic resilience AgEcon
Mondelaers, Koen; Lauwers, Ludwig H..
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.

BRANDING REGIONAL IDENTITY AS A DRIVER FOR RURAL DEVELOPMENT AgEcon
Messely, Lies; Dessein, Joost; Lauwers, Ludwig H..
Within the globalizing world, regions and their identities are subjected to great pressure. At present, places are engaged in a process of “territorial competition” in an integrated world economy. The identity of the region can be used as a starting point to brand a region and differentiate it from others. In the regional branding process, the region as a whole becomes a product or brand and offers a “basket” of regional products and services. This paper discusses the possibility of regional identity as a mobilizing force for rural development, by studying best practice examples of regional branding. Using the grounded theory approach, we conducted interviews in three case regions: West Cork (Ireland), Groene Woud (the Netherlands) and Pajottenland...

Combining risk perception and risk attitude: A comprehensive individual risk behavior model AgEcon
van Winsen, Frankwin; Wauters, Erwin; Lauwers, Ludwig H.; de Mey, Yann; Van Passel, Steven; Vancauteren, Mark.
Although risk management in farming is a well-documented subject in scientific literature, this same literature is usually used only by other scientist and is not aiding individual farmers in their management. Risk perception and risk attitude are well described determinants of risk behaviour but rarely combined in an integrated approach for risk behaviour research. Furthermore in most literature risk attitude is taken as a given stable personality trait on which the optimal behaviour should be based. We argue that risk attitude can be manageable in order to derive optimal risk behaviour. Based on these findings we develop a comprehensive theoretical basic model on farmers risk behaviour. Furthermore a participatory approach involving the stakeholder, the...

Cost-benefit analysis of abatement measures for nutrient emission from agriculture AgEcon
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.

Derogation on the EU Nitrates Directive: does it make a difference? AgEcon
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...

Effectiveness of Nitrate Policy in Flanders (1990-2003): Modular Modelling and Response Analysis AgEcon
Veraet, Mieke; Lauwers, Ludwig H.; Lenders, Sonia; Overloop, Stijn.
The impact of current nitrate policy measures in Flanders is estimated. A modular modelling system has been developed for comparing response and pressure indicators and for decomposing the response impact of policy measures. Compared to 1990, the internalised manure surplus is reduced to zero, whereas the distance to target of the soil surface balance to the water quality standard dropped only with 58%. Source-linked and sink-related measures each account for about the half of the manure surplus reduction. The impact of abatement technologies is minor. The modular approach helps to unravel the discrepancy between pressure and response and to propose policy alternatives.

Effects of a flat rate introduction: shifts in farm activity and impact on farmers' income AgEcon
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...

Exploring production-theoretical insights for analyzing trade-offs between economic performance and environmental pressure at firm level AgEcon
Van Meensel, Jef; Lauwers, Ludwig H.; Van Huylenbroeck, Guido; Van Passel, Steven.
The objective of this paper is to construct a framework for analyzing trade-offs between economic performance and environmental pressure at firm level. Based on a literature review, partially conflicting economic-environmental trade-off paradigms are structured and five necessary conditions for adequate trade-off analysis are put forward. These conditions are delimitating a clear system for which trade-offs are analyzed, assessing the direction of causality between economic performance and environmental pressure, allowing for firm-specific trade-off differences, comprehensiveness with respect to management activities that can be evaluated and flexibility to analyze trade-offs under different market and environmental regulation conditions. To deal with the...

Fertilization: trade-offs between manure abatement and plant productivity AgEcon
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...

Flexible quota constraints in positive mathematical programming models AgEcon
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...

Food Certification Schemes as Private Institutions of Sustainability AgEcon
Mondelaers, Koen; Lauwers, Ludwig H.; Van Huylenbroeck, Guido.
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...

From total farm to household risk: implication for risk management AgEcon
de Mey, Yann; Wauters, Erwin; van Winsen, Frankwin; Vancauteren, Mark; Van Passel, Steven; Lauwers, Ludwig H..
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...

Increase in milk price volatility experienced by Flemish dairy farmers: A change in risk profile AgEcon
van Winsen, Frankwin; Wauters, Erwin; Lauwers, Ludwig H.; de Mey, Yann; Van Passel, Steven; Vancauteren, Mark.
This paper reports on the increased volatility in the milk price received by Flemish dairy farmers and its consequence on the risk profile of selected Flemish dairy farms. The volatility of the milk price has doubled since January 2007. It is suggested that this increasing volatility could have a significant impact on the risk profile of dairy farms. Indeed our results show that the risk profile is changing depending on the volatility and average price for milk. However this change is not very substantial compared to some other subsectors. Also we show that in our case study of selected farms that if the milk price volatility doubles an average milk price increase of about 12% compensates for the increased volatility on return on assets. Finally this paper...

MATERIALS BALANCE BASED MODELLING OF ENVIRONMENTAL EFFICIENCY AgEcon
Lauwers, Ludwig H.; Van Huylenbroeck, Guido.
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...

Modelling Farm Level Economic Potential for Conversion to Organic Farming AgEcon
Kerselaers, Eva; Govaerts, Wim; Lauwers, Ludwig H.; De Cock, Lieve; Van Huylenbroeck, Guido.
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...

Modelling the effects of an abolition of the EU sugar quota on internal prices, production and imports AgEcon
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.

New Developments in Agricultural Policy Modelling and Consequences for Managing the Policy Analysis Systems AgEcon
Van Huylenbroeck, Guido; Lauwers, Ludwig H.; Fernagut, Bruno.
Last decade, the importance of multifunctionality and environmental issues in agricultural policies has been growing. This shift in scope of agricultural policy instruments implies an adjustment of the conventional ex-ante policy analysis systems. New requirements on input and output parameters will be needed. The objective of this paper is to show how the input/output management can be improved. Focus is on how the information management by the system can enhance the policy analysis and decision making and facilitate information flow and social support from the stakeholder debate.

Optimisation of policy interventions in environmental quota AgEcon
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.
