Brief biography

Roger MARTIN-CLOUAIRE was a senior researcher at INRAE (National Research Institute for Agriculture, Food and Environment, former INRA). He holds a Masters in Biomedical Engineering (1982) from Saskatchewan University (Canada) and a PhD (1986) in Artificial Intelligence (AI) from Toulouse University. His research works in these graduate student years focussed primarily on developing and implementing possibility theory models of approximate reasoning in knowledge-based systems.

He joined INRA in 1987 in the mathematics and computer science department where he conducted research projects on various farmers' decision problems and agrosystem management processes. He was the director of the laboratory Unité de Biométrie et Intelligence Artificielle (MIAT presently) from October 2006 to the end of 2010.

He is retired as of July 1, 2021.

Main area of work

Central theme = modelling and simulation of intelligent agents involved in production management tasks

The relevance of simulation approaches to the study and design of agricultural production systems is widely claimed. The methodology and computer software appropriate to such a task have still not reached the state of a mature technology and are mainly developed in research laboratories. Suitable computer models need to represent the structure and dynamics of the underlying biophysical system together with the coordinated human activities involved in the management of the farm production process. Production process improvement involves studying interactions among biophysical processes and decision making processes at the farm level while most existing approaches tend to address one at the expense of the other: the human actor is part of the feedback process, not standing apart from it.

The objective to enhance modelling & simulation capabilities to meet the system research needs yielded to the development (in collaboration with J-P Rellier) of DIESE, a framework especially designed for building and running agricultural production system models. The classical approach to representing decision making in simulation models is to express decision behaviour through a set of decision rules. This approach becomes cumbersome as the number of rules grows beyond a threshold; the meta knowledge about the proper use of the rules (e.g. which should be applied first when several are applicable) is hard to represent and makes the rule-base hard to maintain and reuse. By contrast DIESE relies on a much richer conceptual basis under the form of an ontology of agricultural production systems. It supports the modelling of the decision process in terms of activities, resources required to realize them, and well-structured constraints bearing on the relevance and feasibility of activities, the interdependencies between them and the restrictions on the uses of resources.

Computationally the ontology comes under the form of a C++ library. In developing a farm production system model, the ontology acts as a metamodel; implementing a model amounts to particularizing the ontology concepts as required by the domain and then instantiating the corresponding classes to capture the specific aspects of the system to be simulated. A discrete event simulation mechanism realizes the step by step interpretation of the strategy and the progressive execution of the decided activities, which in turn alter the biophysical state that, otherwise, changes only in response to external factors such as weather.

DIESE is currently used in large modelling projects dealing with various kinds of production such as cash crop, vineyard, pasture-based livestock and pig systems. The development of the ontology was largely inspired by the analysis made in a modelling project on greenhouse tomato production systems. These projects attest to the wide scope of applicability of the framework.

Recent projects

Study of farmers’behavior in making operational decisions

Ph.D. thesis of C. Daydé (december 2013-december 2016):
The thesis proposal focuses on how a farm manager is making operational decisions (choice of actions). It involves characterizing and formalizing the types of information used in the decision-making process and investigating the mechanisms by which they are manipulated and by which constraints, desires and judgement are combined. In order to enable an experimental investigation of such behavior considered as a research object the thesis work should ultimately provide a general and implemented model of the decision process, hopefully covering the variety of decision-making behaviors identified. To be faithful to the reality, the choice has to be done with little processing in order to be compatible with the paucity of information and the fast pace of decision-making observed in farmers’ practices. The investigation dwells on a body of approaches having their roots in qualitative decision, bounded rationality and behavioral economics. For more details see Investigating operational decision-making in agriculture. See also Modelling operational decision-making in agriculture for a BDI-based modelling approach.

Methodology of participatory design approaches with application to the adaptation of livestock systems to climate change

FARMATCH project: The diversity and complementarities of spatio-temporal production patterns and products in livestock systems (ranging from grassland-based to mixed-crop systems) are potential assets to dampen the effects of climatic variability and to adapt to changing climatic or economic contexts. Unfortunately what seems to improve the robustness and efficiency of a livestock system (or reduce its vulnerability) is at the same time increasing its complexity due to the need to manage dynamically several processes that interact in space and time. The main objectives of the FARMATCH project are to:

- analyse adaptation made by livestock farmers in the past and develop a model-based method to assess exposure to climate change and variability;

- develop and diffuse a participatory framework that can support the design of livestock systems adapted to particular climatic, economic, technical, environmental and social aspiration factors.

The workshop-based design framework involves farmers and/or advisors and researchers. Through such workshops the design process exploits intertwining of scientific knowledge and experiential and tacit knowledge of the farmers and advisors. Vulnerability and sustainability (economic and environmental in particular) of the designed systems are assessed thanks to various kinds of models that are also used to convey efficiently knowledge and ensure that a common basis is shared among the participants. The project is structured into 3 WPs: 1- Characterizing vulnerability, 2- Generic principles governing participatory and model-based redesign, and 3- Experimentation with and diffusion of the participatory design framework.

Supporting the acquisition and communication of practical knowledge in agroecology and ecosystem services

A farm system  is not simply a collection of crops and animals to which one can apply simple management rules and expect immediate results. Rather it is a complicated interwoven mesh of soils, plants, animals,  workers, other inputs and environmental influence that are manipulated by  the farmer who, given his knowledge, preferences and resources attempts to achieve his aspirations. Agroecology is a scientific discipline that uses ecological theory to study, design, manage and evaluate agricultural systems that are productive but also resource conserving. The growth of practical knowledge about the production, maintenace and exploitation of ecosystem service is essential toward the implementation of agroecology. This depends largely on the accumulation and organization of information produced by experimental or descriptive research and monitoring activities. Farmers have a key role to play in this “integrative approach” where progress is achieved through the integration of experiential knowledge from different domains (crop, animal, ecology, management,business). A continual learning process must be put in place and the most efficient methods available used to inform this process.See Ontological foundation of ecosystem services and the human dimension of agroecosystems.
