Summary - The transfer method aims to value environmental goods in a fast and cheap way. The principle is to reuse previous results from similar goods valuation and to adapt them in another context. In this paper, the different approaches of transfer are reviewed and formalized. Next it focuses on the transfer reliability assessment methodology. In particular, it analyses empirical results on validity transfer, the only part of reliability considered at this point. In conclusion, neither transfer validity (unbiased method hypothesis) nor the theoretical superiority of model transfer on value transfer have been clearly showed yet. Nevertheless testing process used in most cases was not well adapted to study bias transfer. Moreover model transfers in general were not optimal.

Key-words : transfer, meta-model, reliability, validity.

Summary - This paper deals with manure spreading market in France. We focalize on the capitalization of manure spreading rent in the land market. First, the paper summarizes the literature on land prices. Then we develop a theoretical model based on farm profit maximization for a cattle breeder and a crop grower. It leads to (i) supply and demand for manure spreading rights and (ii) to the integration of the spreading rent in farmland prices. We then provide an hedonic application dealing with 7 000 individual transactions from the land market of Brittany (western France). Land price is explained by land quality and specialization, cereal and milk yields. Land price rises when animal concentration increases. Pig density gets the best results. We conclude making a comparison with the manure market in the Netherlands and dealing with future research.

Key-words : land, hedonic pricing, transferable permits, manure spreading, manure surplus, nitrogen.

Summary - Despite the interest granted by public authorities to landscapes in local development procedures (a concept within the reach of everyone but also cross-disciplinary), an accurate analysis of concrete cases in the Pays-de-la-Loire reveals that the concern for landscapes, henceforth currently integrated at all the scales of public planning policies, is often used by landscape managers to justify their strategies. The landscape topic then often becomes conflicting and, for a geographer, clearly reveals the game of the actors involved. The assessment of landscape policies resorts less from their concrete consequences on landscape planning than from the representations they convey : the images applied by town planners to peripheral rural landscapes permit them to get hold of these peri-urban landscapes where leisure uses develop either against or with agricultural uses. In the process of identity reconstruction, landscapes can trigger either social reconstruction or social breakdown. The request for landscape and the political responses reveal the development of rurality in Europe and, more widely, the development of the social relationships with nature and the environment.

Key-words : peri-urban space, planning policy, landscape assessment, conflict of uses.

Distributive impacts of alternative agricultural policies : a SAM-based analysis for Italy

Summary - This paper assesses the distributive impacts of alternative agricultural policies in a SAM (social accounting matrix) framework. A SAM of the Italian economy has been properly modified in order to focus on agriculture. In doing so, a new method for disaggregating the institutional sectors and the production factors in a SAM framework has been proposed. Two types of analysis have been carried out: (i) a multiplier analysis, and (ii) an assessment of the distributive impacts of different sector policies. The main results can be summarised as follows: (i) ‘fully’ decoupled agricultural household income supporting schemes (transfers to agricultural households) are the most equitable interventions and determine a perfect target of the distributive effect on the relevant institutional sectors; (ii) ‘partially’ decoupled income supporting interventions, such as the ones implemented under the CAP before the Mid Term Review, are more effective than others (i.e., through multiplier effects) in indirectly generating positive impacts on the income of agricultural households; (iii) agricultural price support interventions show less desirable effects in terms of their distributive impacts: they are less effective as agricultural income-increasing policies and their distributive impacts are biased against poorer households both in agricultural and non-agricultural sectors.

Key-words :social accounting matrix (SAM), income distribution, Common Agricultural Policy.
