PresentationMembersPublicationsProjects

To address concerns about the negative environmental impacts resulting from intensive agriculture, agri-environmental policies are designed to provide financial aid to farmers who are willing to voluntarily adopt pro-environmental practices. Conceptual and empirical analysis is required to understand how to promote ecologically-innovative agricultural practices and to design payment schemes inducing the provision of ecosystem services.  First, there is a need to assess the impact of payment schemes that were implemented in the past, as little is known about the actual effectiveness of such programs. Second, the design of innovative instruments is required to address economic and environmental inefficiencies resulting from existing schemes.

This research group tackles these challenges by relying on research expertise in applied econometrics, structural econometrics, experimental economics and incentive theory. More specifically, we use experimental and quasi-experimental methodologies as well as contract theory.

Research works are focused on two main priorities. The first one is related to the impact of agri-environmental policies that were implemented in the last decade in Europe and in tropical areas. The most recent micro-econometric methods are used to assess the potential inefficiencies resulting from these initiatives. The second priority focuses on the design of innovative instruments that better account for global changes and for constraints borne by potential providers of environmental services.

CAPTION – Evaluation of CAP 2015-2020 and Taking Action
  • Funding : 42,000 € Fondations Cariplo et Agropolis
  • Duration : 2019 – 2020
  • Contact : THOYER Sophie

In the near future, the CAP will undergo through a process of change and restructuring, both for the need to revise and reform its policy instruments and to account for the outcomes of EU budget reshape. As a first step, the EU Commission is gathering stakeholders’ comments and suggestions on its document « Communication on Modernizing and Simplifying the CAP”, prefiguring five possible development options for the future CAP. In this context, the CAPTION Project aims at contributing to such debate, providing scientific-based evidence on current impact of CAP and giving insights on innovative policy tools. Such kind of analysis is particularly relevant for examining and monitoring the new policy tools (greening payment) implemented in the current CAP programming period 2015-2020. Furthermore, the project provides possible alternatives with respect the current policy instruments in order to tackle the issues not properly covered by them. The research project includes two distinct Work Packages (WP). WP1 focuses on the implementation of a series of impact evaluations of the economic and environmental effects of the current 2015-2020 CAP, in support of drafting scenarios and simulations for the post-2020 CAP. WP2 focuses on a specific category of farms not or partly involved in the implementation of the CAP: the small farms.

POLLDIFF CAPTAGE – Améliorer la qualité de l’eau

Comment bien appréhender la gestion des masses d’eaux superficielles et souterraines, des risques associés à leurs usages, et l’agroenvironnement dans un contexte de changements globaux ?
Ce projet vise à proposer et à tester sur le terrain des mesures innovantes pour améliorer l’adoption de pratiques agricoles plus respectueuses de la qualité de l’eau. Il permettra (1) de proposer des mesures innovantes ; (2) de mener des évaluations ex-ante pour identifier les mesures les plus pertinentes ; (3) de proposer des dispositifs de suivi-évaluation et des protocoles d’expérimentation sociale pour évaluer expost l’impact de la mesure en construisant une situation contrefactuelle. Il vise à valoriser les résultats acquis par l’économie comportementale et expérimentale pour améliorer l’efficacité des plans d’actions agro-environnementaux.

C4EAU – Compteurs d’eau Communicants et Changement de Comportement des irrigants pour une gestion durable des ressources en eau
  • Funding : 75,000 € Région Occitanie Appel à projets Recherche et société(s)
  • Duration : 2018 – 2020
  • Contact : PREGET Raphaele

Les nouvelles technologies offrent de nouveau moyens pour améliorer la gestion des ressources en eau dans les territoires. Pour donner leur pleine mesure, elles doivent cependant s’accompagner de modification des comportements individuels et collectifs. Cela requiert une compréhension fine des effets de comportement (mimétisme, norme sociale, etc.) de manière à pouvoir proposer des dispositifs innovants pour renforcer l’efficacité de l’action publique et pour améliorer son acceptabilité et sa légitimité. Ce projet propose trois directions d’analyse 1/ évaluer l’impact des compteurs communicants sur la consommation individuelle des agriculteurs, 2/ proposer et évaluer des « interventions » utilisant les compteurs communicants pour réduire la consommation individuelle des agriculteurs, 3/ identifier des mécanismes efficaces pour inciter à l’adoption volontaire de compteurs communicants par les irrigants. Le projet est fondé principalement sur des approches d’économie comportementale, et il s’appuie sur l’expertise technique de la Compagnie d’Aménagement des Coteaux de Gascogne (CACG) en matière de gestion territoriale de l’eau. Les analyses empiriques seront conduites sur les cas d’études situés en région Occitanie, en concertation avec la CACG, partenaire technique du projet.

POLNISO – Instruments to encourage greater adoption of cover crops
  • Funding : INRA-SAE2 (projet jeune chercheur)
  • Duration : 2018 – 2019
  • Contact : SAUQUET Alexandre

The use of fertilizers in agriculture is one of the main source water pollution. The use of cover crops after harvesting the main crop allows reducing the transfer of nitrates to groundwater during the rainy season. In France, from 2000 to 2014, two measures encouraged cover cropping: one is regulatory (through the nitrates directive), one is market-based (agro-environmental schemes of the common agricultural policy). Our purpose is to study which one, or which combination, of the two measures allowed the widest adoption of the cover cropping practice. To this end, we develop an analytical framework and test formulated hypotheses using micro-econometrics methods applied on farm-level data.

CEE-M/CIFOR – Impact evaluation of a pilot REDD+ project in the Trans-Amazonian region in Brazil

In this project, we use the introduction of the first PES-based REDD+ project ever launched in Brazil by a Non-Governmental Organization in the region of Para in 2012 as a natural experiment in order to evaluate the long-run impact of this project.

In particular, we focus on the permanence of the effects of this REDD+ project by collecting new data from the baseline sample, about three years after the PES program starts.
This study is financed and undertaken in close collaboration with the Center for International Forestry Research (CIFOR), as part of its Global Comparative Study (GCS) on REDD+, and with the Brazilian non-governmental organization in charge of the implementation of the PES program, the Amazon Environmental Research Institute (IPAM).

PENSEE – Payments for ENvironmental Services: an Evidence-based Evaluation

In order to strike the right balance between agriculture and the environment, policymakers in both developed and developing countries are increasingly resorting to Payments for Environmental Services (PES).
PESs are contracts between a farmer and the government in which the farmer receives a payment in exchange for the adoption of greener practices. PES programs usually aim to tackle major current environmental issues but can be expensive. It is thus critical to provide credible evaluations of their effectiveness.
Yet, evidence on their impact remains scarce.

This project aims to fill this gap by using modern econometric methods, such as experimental and quasi-experimental techniques, to provide the first evidence-based evaluations ever made for a series of agri-environmental programs in France: the French program to reduce the use of pesticides, the French grassland conservation programs, two pilot programs based on nudges, one aimed at encouraging biological control in viticulture and the other to reduce the consumption of agricultural water
