Are EU spatial ex ante coexistence regulations proportional? AgEcon
Demont, Matty; Daems, W.; Dillen, Koen; Mathijs, Erik; Sausse, C.; Tollens, Eric.
The EU is currently struggling to implement coherent coexistence regulations on genetically modified (GM) and non-GM crops in all member states. While it stresses that any approach needs to be “proportionate to the aim of achieving coexistence”, very few studies have actually attempted to assess whether the proposed spatial ex ante coexistence regulations (SEACERs) satisfy this proportionality condition. In this article, we define proportionality as a functional relationship which is weakly increasing in the incentives for coexistence. We propose a spatial framework based on an existing landscape and introduce the new concept of shadow factor as a measure for the opportunity costs induced by SEACERs. This enables comparing the proportionality of (i) rigid...

Characteristics of the agricultural sector of the 21st Century AgEcon
Troskie, Dirk P.; Mathijs, Erik; Vink, Nick.
The objective of this paper is to identify some of the salient characteristics of agriculture in the new millennium. The driving force behind economic change is technology and information, and information and knowledge will replace land, labour and capital as the sources of wealth in agriculture. The resultant cognitive-technical complex in farm production will lead to the true industrialisation of farming and thus placing the traditional family farmer at a distinct disadvantage. Technology developments combined with inverse population growth and ageing population, will not only negate Malthusian visions, but also lead to downward pressure on farm commodity prices, and thus increase the adoption rates of new technology. However, in reaction to the...

Commercialization and Subsistence in Transaction Agriculture: Empirical Evidence from Albania, Bulgaria, Hungary and Romania AgEcon
Mathijs, Erik; Noev, Nivelin.
Present-day Central and Eastern European agriculture is characterized by a high incidence of small-scale farmers who are not producing for the market. This paper uses household level data from comparative farm surveys in Albania, Bulgaria, Hungary and Romania to analyze which farm household characteristics and endowments influence commercialization and subsistence farming.

CONSUMER WILLINGNESS TO PAY FOR DOMESTIC MILK AgEcon
Vandermersch, Mieke; Mathijs, Erik.
Dairy farmers'’ profit margins are under pressure due to the downward trend of EU commodity prices for fluid milk and the increasingly powerful retail sector, in combination with increasing production costs. A likely solution to counter small margins is to add value to raw milk. This paper investigates the option of using a domestic origin-certification to upgrade the value of milk. Data stem from a consumer survey, conducted at the three largest supermarket chains in Flanders (Belgium). The results show evidence for a latent demand for domestic milk. Based on actually purchased brands in combination with top-of-mind attributes, two consumer types were distinguished (price-shoppers and added-value seekers), each with a different behaviour concerning...

Contingent valuation analysis of rural households’ willingness to pay for frankincense forest conservation AgEcon
Tilahun, Mesfin; Mathijs, Erik; Muys, Bart; Vranken, Liesbet; Deckers, Jozef A.; Gebregziabher, Kidanemariam; Gebrehiwot, Kindeya; Bauer, Hans.
Frankincense from Boswellia papyrifera forest (BPF) is a traded non timber forest product (NTFP) used in pharmaceutical, food, cosmetic and chemical industries. However, the resource in northeastern Africa is under continuous degradation and requires conservation measures. Data from a discrete choice contingent valuation study are used to assess the factors influencing rural households’ willingness to pay (WTP) and willingness to contribute labor (WTCL) for BPF conservation in Ethiopia. The standard probit, bivariate probit and interval data models were used for modeling respondents’ WTP and WTCL. We found household income as the most important factor affecting WTP whereas number of household labor is the most important factor affecting WTCL. Mean lower...

Determinants of Romanian Farmers' Participation in Agri-Environmental Programmes AgEcon
Toma, Luiza; Mathijs, Erik.
The paper aims to identify the factors underlying farmers' propensity to participate in agri-environmental programmes in a Romanian rural region that confronts non-point source pollution. For this, we employ structural equation modelling with latent variables using data collected through an agri-environmental farm survey in 2001. The model includes one 'behavioural intention' latent variable ('propensity to participate in agri-environmental programmes') and five 'attitude' and 'socioeconomic' latent variables ('demo-social characteristics', 'economic characteristics', 'agri-environmental information access', 'environmental risk perception' and 'general environmental concern'). The results indicate 'environmental risk perception' as the strongest...

Do Management Profiles Matter? An Analysis of Belgian Dairy Farmers AgEcon
Vandermersch, Mieke; Mathijs, Erik.
To assess the performance of a farmer and to identify best practice among a group of farmers, the assumption is often made that all farmers maximize profits and thus share the same business goals. However, performance differs due to personal characteristics, objectives and strategies. A survey carried out among 73 Belgian dairy farmers revealed that for only 34% of the farmers "profit maximization" is a primary objective. A regression analysis revealed that self-declared profit maximizers only obtained a higher farm income per liter, not per labour unit. Through cluster analysis, four main groups of farmers were found with similar objectives and management ideas: (A) risk-taking and progressive cow farmers, (B) riskaverse and progressive labour savers, (C)...

Economics of spatial coexistence of genetically modified and conventional crops: Oilseed rape in Central France AgEcon
Demont, Matty; Daems, W.; Dillen, Koen; Mathijs, Erik; Sausse, C.; Tollens, Eric.
Europe is currently struggling to implement coherent coexistence regulations on genetically modified (GM) and non-GM crops in all EU Member States. We conduct simulations with the software ArcView® on a GIS dataset of a hypothetical case of GM herbicide tolerant oilseed rape cultivation in Central France. Our findings show that rigid coexistence rules, such as large distance requirements, may impose a severe burden on GM crop production in Europe. These rules are not proportional to the farmers’ basic incentives for coexistence and hence not consistent with the objectives of the European Commission. More alarming, we show that in densely planted areas a domino-effect may occur. This effect raises coexistence costs and even adds to the non-proportionality...

Explaining Differences in Farm Sustainability: Evidence from Flemish Dairy Farms AgEcon
Van Passel, Steven; Mathijs, Erik; Van Huylenbroeck, Guido.
An important objective of European agricultural policy is to have a sustainable, efficient farming sector, which uses environmentally-friendly production methods. Agricultural policy makers aim to combine strong economic performance with a sustainable use of natural resources. There is thus a need for tools allowing quantification of farm sustainability as well as for empirical research assessing, analysing and explaining differences in farm sustainability. Using a large dataset of dairy farms, we apply the concept of sustainable value creation to benchmark farm sustainability performance. An effect model captures the determinants of the differences in sustainability among Flemish dairy farms. Our empirical model shows that both managerial and structural...

FARM RESTRUCTURING AND EFFICIENCY IN TRANSITION: EVIDENCE FROM BULGARIA AND HUNGARY AgEcon
Mathijs, Erik; Vranken, Liesbet.
Based on survey data on Bulgarian and Hungarian crop and dairy farms, a double-peaked distribution of technical efficiency is observed. Several factors explain differences in efficiency. Human capital matters not only through age and education, but also through gender as farms with a higher share of women are more efficient. Contracting with upstream processors increased efficiency through facilitating the adoption of technology and the access to credits. The superiority of family farms over corporate farms is confirmed for crops but not for dairy.

Linkages between Agriculture, Trade and the Environment in the Context of the European Union Accession AgEcon
Toma, Luiza; Mathijs, Erik; Revoredo-Giha, Cesar.
This paper analyses the impact of trade on environment in Romania using a partial equilibrium model of bilateral trade in beef between Romania and the EU. We use a recursive dynamic model to analyse beef production and trade and adjust it as to include a component to evaluate the impact of liberalised trade due to Romania’s accession to the EU on groundwater and air quality. The environmental module of the model associates the pollution to the use of production inputs. We link the use of itrogen inputs (e.g., nitrogenous fertilisers, manure) to nitrogen loss through leaching/runoff into groundwater (nitrates) and greenhouse gases (emissions of nitrous oxide and methane). We compute the nitrogen loss through leaching/runoff into the groundwater based on the...

POST-COMMUNIST AGRICULTURAL TRANSFORMATION AND THE ROLE OF HUMAN CAPITAL: EVIDENCE FROM ROMANIA AgEcon
Rizov, Marian; Mathijs, Erik; Swinnen, Johan F.M..
Farm restructuring in post-communist transition countries has resulted in a broad range of farm types, such as cooperatives, companies, partnerships and sole proprietorships. This study examines which factors affect production organization choices of rural households with an emphasis on the role of human capital in the agricultural transition process. We use a multinomial logit model and data from a nation-wide survey of Romanian farms, organized in 1996. The results of the empirical tests support the main hypothesis that the transformation process outcome depends primarily on human capital and farm physical capital endowments of the household, translated into household income by the household entrepreneurial input. Entrepreneurial ability is...

Rural livestock asset portfolio in northern Ethiopia: A microeconomic analysis of choice and accumulation AgEcon
Tegebu, Fredu Nega; Mathijs, Erik; Deckers, Jozef A.; Tollens, Eric.
Livestock of different species fulfill different functions. Depending on their livelihood strategies, households differ in their choice of type of animal to keep and accumulation of the chosen animal overtime. This paper investigates the dynamic behavior of rural households’ livestock holding to identify determinants of choice of type of animal households’ keep and accumulation of the chosen animals using a panel data of 385 rural households in a mixed farming system in northern Ethiopia. Dynamic behavior of choice is analyzed for a principal animal, an animal that constitutes the largest value of livestock assets a household possesses, using a multinomial logit model. A household that keeps oxen as a principal animal is considered the reference household....

Social Capital and Farmers' Willingness to Adopt Countryside Stewardship Schemes AgEcon
Mathijs, Erik.
The EU provides farmers with incentives to adopt Countryside Stewardship Schemes (CSS) using subsidies in the framework of the agri-environmental regulation of the EU (2078/92), now included in the more general regulation on rural development In this paper, a case study of 36 farmers in the village of Bierbeek, was carried out to investigate the determinants of the willingness to adopt a scheme involving taking care of arable field margins in particular. Bivariate and multivariate logit analysis confirmed not only the importance of personal, structural and financial factors, but also showed the importance of social capital. Farmers who are more open to both professional and nonprofessional contacts are more likely to adopt a CSS. Hence, government and...

Sustainable Development of the Flemish Greenhouse Industry AgEcon
Verwilt, Poi; Mathijs, Erik.
This paper addresses the sustainable development of the Flemish greenhouse industry by investigating the optimal size, structure and location of its farms. It emphasizes the importance of a square shape of the greenhouse as optimal structure. Using Data Envelopment Analysis an optimal farm size that varies between 1.7 and 3 hectares has been found, depending on the method used. Location factors that matter in the future Flemish greenhouse industry include temperature, light, transportation costs, air pollution and land prices, while rainfall, wind, output price differences, soil and infection risk do not differentiate between regions.

Sustainable food versus health concerns AgEcon
Avermaete, T.; Mathijs, Erik.
Simultaneous with the growing demand for sustainable food, statistics in all EU member states report consumption patterns that are characterized by too much fat, overdoses of sugar and a lack of fruits and vegetables. The streams of literature that investigate the factors influencing sustainable food consumption and healthy food consumption are largely separated. However, the question whether there is a positive relationship between consumer behaviour towards sustainable food and consumer behaviour towards healthy food remains largely unanswered. The purpose of this paper is to examine the relationship between the consumption of different types of sustainable food on the one hand, and healthy food patterns on the other. The study is based on a sample of...

THE ALLOCATIVE EFFICIENCY OF LAND RENTAL MARKETS IN TRANSITION AGRICULTURE AgEcon
Vranken, Liesbet; Mathijs, Erik.
This paper examines the functioning of the Hungarian land rental market. The allocative inefficiency of the land rental market is determined by calculating the marginal value productivity of land and using rental prices. Regional differences in allocative inefficiency are then correlated with demographic and socio-economic variables and with labor market-related factors.
