Although Markov chain models have enjoyed decades of popularity in forecasting total farm numbers, they generally fail to provide a detailed insight of the farm population’s structure; to overcome this caveat we estimate a parametric distribution of the utilized agricultural area of French commercial farms. Our method provides detailed information on the structure of the population and accounts for the specificity of off-land farming. We also model the influence of variables such as the farm’s legal status, type of farming and farm holder’s age. The estimation leads to a relevant description of the entire population of professional farm. When compared with the 2005 Farm Structure Survey data, our simulations based on FADN data display a close match across a number of key variables.","PeriodicalId":170092,"journal":{"name":"Revue d’études en Agriculture et Environnement","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125239898","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To address the endogenous and binary nature of the household's credit constraints status, we employ a treatment-effects model to consistently estimate the effect of credit constraints. Results reveal that after effectively correcting for endogeneity, credit constraints have a negative and significant effect on the amount of land allocated to hybrid maize. Results also show that farmers with larger land holdings allocate more land to hybrid maize. Although less likely to report credit constraints, older farmers allocate less land to hybrid maize than younger farmers. These findings suggest that there is scope for increasing the cultivation of hybrid maize in Malawi if credit is targeted at younger farmers that are credit-constrained.","PeriodicalId":170092,"journal":{"name":"Revue d’études en Agriculture et Environnement","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-06-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117071430","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

La theorie prevoit que l’equilibre de frequentation est alors non optimal en raison d’un effet externe d’encombrement. Alors que des travaux anciens ont caracterise equilibre et optimum dans le cadre de modeles mono-site a demande continue (Fisher et Krutilla, 1972), les rares articles recents utilisant les modeles de choix discret se sont limites a etudier empiriquement l’equilibre et la repartition des visites entre les sites. Notre modele theorique permet de formaliser l’equilibre et l’optimum de frequentation, dans le cadre d’un modele de choix discret a deux sites integrant la decision de participation des individus, ainsi que certains instruments de gestion permettant d’ameliorer le bien-etre. Il a ete necessaire de recourir a une formulation generale du bien-etre definie par Erlander (2005). On montre que les individus participent trop et visitent trop le site de meilleure qualite (et pas assez le site de qualite inferieure) a l’equilibre. En exprimant les desutilites collectives liees a la participation et a la mauvaise repartition des visites entre les sites, le modele permet d’en deduire les taxes optimales et les effets sur le bien-etre collectif d’une augmentation de la qualite des sites.

Llerena","doi":"10.3406/reae.2009.1967","DOIUrl":"https://doi.org/10.3406/reae.2009.1967","url":null,"abstract":"Il est de coutume d'associer a la protection de l'environnement l'idee que l'intervention des pouvoirs publics represente uniquement des couts supplementaires pour les agriculteurs. Cependant, depuis quelques annees, ce paradigme est remis en cause par de nombreuses etudes. Par exemple, Porter et van der Linde (Porter, 1991; Porter and van der Linde, 1995) considerent que la pollution est souvent associee a une sous utilisation des ressources (matiere premiere, energie, etc.) et que l'existence de politiques environnementales plus strictes peut stimuler l'innovation et, par la meme, aboutir a une compensation des couts supportes par les entreprises regulees. En realite, il existe de multiples canaux par lesquels une amelioration de la performance environnementale des exploitations agricoles peut aboutir a de meilleures performances economiques, ou en tout cas pas necessairement a un accroissement des couts d'exploitation. Pour etre systematique, il faut examiner les impacts de la performance environnementale non seulement en termes de revenus additionnels, mais egalement en termes de reduction des couts. En suivant le cadre d'analyse propose par Reinhardt (2000), Lankoski (2000, 2006) et Lanoie et Ambec (2007), nous pouvons tout d'abord constater qu'une amelioration des performances environnementales peut induire un accroissement des recettes via trois canaux : i) l'acces a de nouveaux marches,; ii) la possibilite de differencier les produits et iii) la possibilite de vendre des technologies environnementales. Par ailleurs, une meilleure performance environnementale peut egalement se traduire par une reduction des couts dans les categories suivantes : iv) couts reglementaires; v) couts des matieres premieres, des intrants et de l?energie; vi) cout du capital et vii) cout du travail. L'objectif de cet article est d'appliquer ce cadre d'analyse au secteur agricole. Plus precisement, a l'aide d'illustration et d'etudes de cas, nous analysons pour chacun des sept points presentes ci-dessus les relations qui peuvent exister entre la performance environnementale des exploitations agricoles et leur performance economique. Si certains auteurs ont deja etudie la rentabilite de differentes mesures ou techniques agro-environnementales, il n'existe pas a notre connaissance d'etudes systematiques. De plus, les exemples concrets d'experiences menees en France et au Quebec montrent que la question de l'impact des pratiques environnementales sur la rentabilite des entreprises reste d'actualite, et que les approches proposees peuvent etre une source d?inspiration pour les agriculteurs en reflexion quant a leur decision d?investir ou non en matiere de protection de l'environnement.","PeriodicalId":170092,"journal":{"name":"Revue d’études en Agriculture et Environnement","volume":"99 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127705832","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is worth taking into account two types of rural areas : rural areas under urban influence and independent rural areas.

We extend the traditional contingent valuation method by introducing seven dichotomous choice occasions. To answer each valuation question, each respondent is asked to choose between a policy scheme and the status quo. Each scheme is composed of various programmes while each programme is linked to the recreational quality of one natural area. An extra distance is used as a proxy of the bid. The results show that respondents distinguish between schemes according to the number of programmes included. Nevertheless, a “substitution effect” occurs when all programmes are supposed to be implemented. Individual WTP ranges from €6.51 for the forest alone (e.g. 55.35 extra kilometres per group-vehicle) to €18.11 (e.g. 153.9 extra kilometres per group-vehicle) for the complete scheme. Our results stress the fact that recreation in forests must not be isolated from other natural areas. From a more general point of view, valuation based on multi-attribute approaches must be favoured on “multi-environment” sites.","PeriodicalId":170092,"journal":{"name":"Revue d’études en Agriculture et Environnement","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128225459","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
