“…Thus, the model accounts for intergenerational equity and allows for conciliation between the present and the future. By identifying current public‐policy decisions that avoid future crises without penalizing the current generation, the viability approach is consistent with the definition of sustainability especially through its links with the maximum (or Rawlsian) approach (i.e., approach focused on the maximization of the poorest generation) as emphasized in Doyen and Martinet ().…”

Substantial declines in farmland biodiversity have been reported in Europe for several decades. Agricultural changes have been identified as a main driver of these declines. Although different agrienvironmental schemes have been implemented, their positive effect on biodiversity is relatively unknown. This raises the question as to how to reconcile farming production and biodiversity conservation to operationalize a sustainable and multifunctional agriculture. We devised a bioeconomic model and conducted an analysis based on coviability of farmland biodiversity and agriculture. The coviability approach extended population viability analyses by including bioeconomic risk. Our model coupled stochastic dynamics of both biodiversity and farming land-uses selected at the microlevel with public policies at the macrolevel on the basis of financial incentives (taxes or subsidies) for land uses. The coviability approach made it possible for us to evaluate bioeconomic risks of these public incentives through the probability of satisfying a mix of biodiversity and economic constraints over time. We calibrated the model and applied it to a community of 34 common birds in metropolitan France at the small agricultural regions scale. We identified different public policies and scenarios with tolerable (0-0%) agroecological risk and modeled their outcomes up to 2050. Budgetary, economic, and ecological (based on Farmland Bird Index) constraints were essential to understanding the set of viable public policies. Our results suggest that some combinations of taxes on cereals and subsidies on grasslands could be relevant to develop a multifunctional agriculture. Moreover, the flexibility and multicriteria viewpoint underlying the coviability approach may help in the implementation of adaptive management.

“…In practical management situations, identifying such thresholds would need to involve stakeholders, and the results of such sensitivity analysis could inform the process of deciding on adequate values to retain for a viability assessment, as has been shown by [55]. The strong links between maximin and viability approaches pointed out in [23] can also bring important insights in this respect.…”

Fisheries management must address multiple, often conflicting objectives in a highly uncertain context. In particular, while the bio-economic performance of trawl fisheries is subject to high levels of biological and economic uncertainty, the impact of trawling on broader biodiversity is also a major concern for their management. The purpose of this study is to propose an analytical framework to formally assess the trade-offs associated with balancing biological, economic and non-target species conservation objectives. We use the Australian Northern Prawn Fishery (NPF), which is one of the most valuable federally managed commercial fisheries in Australia, as a case study. We develop a stochastic co-viability assessment of the fishery under multiple management objectives. Results show that, due to the variability in the interactions between the fishery and the ecosystem, current management strategies are characterized by biological and economic risks. Results highlight the trade-offs between respecting biological, economic and non-target species conservation constraints at each point in time with a high probability and maximizing the net present value of the fishery.

“…First and foremost, resilience is about dynamic systems, including the possible existence of feedbacks, nonlinear trajectories, and thresholds. This sustainable zone is the multidimensional space within which the system is viable, that is, does not violate its viability constraints today and in the future (Baumgärtner & Quaas, 2009;Cissé et al, 2013;Doyen et al, 2017;Doyen & Martinet, 2012;Mouysset et al, 2013;Schuhbauer & Sumaila, 2016). Derived from control theory (Bellman, 1964), the aim of viability approach is to analyze the compatibility between the (possibly uncertain) dynamics of a system and a series of constraints and to determine a set of controls, actions, or decisions that would allow the system to stay within the "sustainable zone" defined by the limits of the various constraints.…”

From Resistance to Transformation: A Generic Metric of Resilience Through Viability

In the last two decades resilience has emerged as a promising concept that can help societies and more generally social‐ecological systems become less vulnerable to shocks and stressors. As such it has been adopted by a large number of disciplines—from psychology, physics, and ecology to disaster risk reduction, climate change adaption, and humanitarian and food security interventions. However, although numerous definitions or measures of resilience have been proposed, those were mainly discipline centered and, as such, failed to provide an adequate overarching framework. This paper explores the question of the formalization and measurement of resilience, with the objective to develop a generic metric that applies across the disciplines and to the different interpretations of resilience. Building on the definitions found in the literature, a continuum of five categories of resilience responses is identified: (i) resistance, (ii) coping strategies, (iii) adaptation, (iv) adaptive preference, and (v) transformation. Those categories are then reframed into a generic metric, using viability analysis—a mathematical formalism which builds on dynamic systems and control theory. Theoretical and empirical analyses are then conducted, looking in particular at how inertia and costs associated with the types of responses influence the level of resilience. To illustrate this new metric, we draw on two models widely discussed in the resilience literature: the exploitation of renewable resources and the case of lake eutrophication. Both theoretical and numerical analyses demonstrate the relevance of the typology as a generic framework for resilience but also highlight transformation as a particular case of resilience response.
