Parrot, Laurent

Laurent R Parrot, economist, DrHDR. His current research focuses on the components of the alliance approach as applied to economics. The alliance approach stems from the behavioral and cognitive sciences in human health - the working alliance. This approach is applied to the fields of agriculture and environmental sciences at plot, farm, value chain, and governance levels.

Parrot, L. (2024) . Peut-il exister un développement durable sans alliance ? Le rôle de l’évaluationMondes en développement, N° 207(3), 51-70. Numéro spécial "Politiques de développement, acteurs et évaluations".  https://doi.org/10.3917/med.207.0051.

Toutes les techniques et toutes les interventions sont des actes relationnels. Il n’existe ainsi pas de bonne ou de mauvaise évaluation, mais plutôt des critères d’évaluation et, par conséquent, de jugement, qui conviennent aux personnes et aux institutions concernées. Dans le cadre d’un développement durable, la question consiste à caractériser la qualité de cette relation. Nous mobilisons l’approche par l’alliance issue des sciences comportementales et cognitives dans les sciences médicales. Nous nous appuyons sur deux études de cas au Burkina Faso et en Martinique et sur deux principes de l’alliance – l’authenticité et la reconnaissance du statut de la personne – pour illustrer les différents intérêts que peuvent procurer l’évaluation au-delà de la dimension technique de sa mesure.

The informal sector adds a systemic layer of uncertainty and risk for the performance of Food Supply Chains in sub-Saharan Africa. Firms internalise the risks with horizontal and vertical integration, the support of subsidies, or by avoiding the costs of international standards compliance. As a result, we distinguish subsidised resilience from informal resilience.

Toutes les techniques et toutes les interventions peuvent se réduire à des actes relationnels. Le succès d’une technique ou d’une intervention revient donc à décomposer puis analyser la qualité des actes relationnels sous-jacents. Nous avons décliné ce postulat auprès des filières canne et maraîchage en Martinique. Cet article ouvre la boite noire des variables « relationnelles et cognitives » en sciences politiques et en sciences économiques.

Si la confiance exprime la volonté d'une partie d'être vulnérable aux actions d'une autre partie, les stratégies de diversification, destinées à réduire les vulnérabilités, peuvent paradoxalement affaiblir la confiance. Nous testons cette hypothèse auprès de l’agriculture maraîchère en Martinique.
