Titre: Selected papers from the 2015 Workshop on Non-market Valuation (WONV) in Nancy Auteur:Garcia, Serge; Mahieu, Pierre-Alexandre Sujet:Environmental Economics and Policy Description:
At the beginning of 2012, a small group of economists working on non-market valuation, led by Pierre-Alexandre Mahieu, decided to meet regularly to share their knowledge on valuation methods. The main objectives of this workshop were (i) to provide a forum for dissemination of high-quality papers presenting recent developments in theoretical and empirical analyses in the field of non-market valuation and (ii) to create a network of researchers (including worldwide experts) that would meet every year. WONV quickly became an annual international workshop. Every year, about 30 researchers meet in a different European city. Both theoretical and applied papers dealing with stated preference methods (e.g., contingent valuation, choice experiments) and revealed preference methods (e.g., travel cost method, hedonic pricing method) are presented. Empirical applications mainly deal with environmental and resource economics but applications to other domains (e.g., health, agriculture) are welcome.

Titre: The tourist recreational demand for coastal forests: Do forests really matter? Auteur:Rulleau, Bénédicte; Dehez, Jeoffrey; Point, Patrick Sujet:Environmental Economics and Policy Description:
This paper explores the possible impact of the combination of forest and non-forest settings on recreation values. 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.

Titre: Introduction: Farmer’s adaptation to environmental changes Auteur:Drogué, Sophie; Jacquet, Florence; Subervie, Julie Sujet:Environmental Economics and Policy Description:
This introduction summarizes some of the key research findings from the articles included in this special issue of The Review in Agriculture and Environment Studies. These articles were drawn from an INRA-funded workshop held in Montpellier in September 2012 entitled Adaptation Practices and Adoption of New Technologies. The workshop focused on current research in agricultural economics and farm management that extends beyond the study of productivity. Specifically, research in this area now also aims to provide a better understanding of farmers’ ability and willingness to respond to new environmental challenges. In particular, these challenges pertain to adaptation to the changing climatic context and recent developments in environmental policies. The selected articles address the issue of farmers’ adaptation to environmental changes in light of their individual preferences. In brief, their findings indicate that taking heterogeneity into account is indeed crucial when analysing or promoting new adaptation strategies.

Titre: Greenhouse Gas Emissions of Beef Cow-Calf Grazing Systems in Uruguay Auteur:Becona, Gonzalo; Astigarraga, Laura; Picasso, Valentin D Sujet:Environmental Economics and Policy Description:
Evaluating greenhouse gas (GHG) emissions at farm level is an important tool to mitigate climate change. Livestock account for 80% of the total GHG emissions in Uruguay, and beef cow-calf systems are possibly the largest contributors. In cow-calf grazing systems, optimizing forage allowance and grazing intensity may increase pasture productivity, reproductive performance, beef productivity, and possibly reduce GHG emissions. This study estimated GHG emissions per kg of live weight gain (LWG) and per hectare from 20 cow-calf systems in Uruguay, with different management practices. The GHG emissions were on average 20.8 kg CO2-e.kg LWG-1, ranging from 11.4 to 32.2. Beef productivity and reproductive efficiency were the main determinants of GHG emissions. Five farm clusters were identified with different productive and environmental efficiency by numerical classification of relevant variables. Improving grazing efficiency by optimizing the stocking rate and forage production can increase beef productivity by 22% and reduce GHG emissions per kg LWG by 28% compared to “low performance” management. Further improvements in reproductive efficiency can increase productivity by 41% and reduce GHG emissions per kg LWG by 23%, resulting in a “carbon smart” strategy. However, the most intensified farms with highest stocking rate and beef productivity, did not reduce GHG emissions per kg LWG, while increased GHG emissions per ha compared to the carbon smart. This analysis showed that it is possible to simultaneously reduce carbon footprint per kg and per ha, by optimizing grazing management. This study demonstrated that there is high potential to reduce cow-calf GHG emissions through improved grazing management.

Titre: The forest-based sector and research – some thoughts on relevance and future prospects Auteur:Hoen, H-F Sujet:Environmental Economics and Policy Description:
We are 14 years into the 21st century. Forest sciences and research, a multifaceted combination of a number of academic disciplines, have existed and developed over several decades. In this note, I first discuss some current societal challenges or “drivers”, then how this relates to forestry and forest industries (the forest-based sector – FBS) as a profession and business. This is followed by a simple check to what degree we researchers (within forest economics and management planning) have dealt with these topics recently. Finally, I give some ideas for research priorities, with emphasis on the area of forest economics and management. The viewpoint is from Norway, a forest-rich country, with a fairly specialised or concentrated forest industry, currently facing large structural changes.
