Marin Guinard nous présentera son article intitulé : “Targeting Agrivoltaics for Food Systems and Rural Equity: An environmental accounting approach for France”.
Abstract: Rapid solar expansion is essential for decarbonisation but increasingly competes with agricultural land and valued rural landscapes, raising siting conflicts and equity concerns. Agrivoltaics (AV)—the co-location of photovoltaic panels and farming—has been proposed as a way to ease these tensions by jointly producing energy and supporting agricultural adaptation. Yet AV benefits are highly context-dependent and current spatial suitability studies often remain techno-centric, providing limited insight into trade-offs between energy performance, climate resilience, agricultural transition and rural socio-economic goals. We propose a transparent, non-monetary, policy-oriented framework to support multi-objective AV targeting in metropolitan France at the commune level. We operationalise four pillars—Energy (E), Climate (C), Agricultural practices (A) and Socio-economic resilience (S)—built from observable indicators identified through stakeholder interviews and a targeted literature review. Indicators are normalised to [0,1] using winsorised empirical CDFs and aggregated into pillar scores, which are then combined into a scenario-based composite value function with explicit weights and optional concave utilities. Applied to ~34,500 communes, the pillars show strong internal heterogeneity, low cross-pillar correlations, and limited overlap of top-decile areas, indicating that multi-criteria “sweet spots” are scarce and that policy narratives imply distinct spatial priorities. The framework provides a reproducible decision aid to reveal synergies and trade-offs, compare alternative deployment strategies and support more equitable and strongly sustainable AV rollout.
