This theoretical paper synthesises research on the foundational economy and its contribution to a social–ecological transformation. While foundational thinking offers rich concepts and policies to transition towards such transformation, it fails to grasp the systematic non-sustainability of capitalism. This weakness can be overcome by enriching contemporary foundational thinking with feminist and ecological economics. Whereas the feminist critique problematises foundational thinking’s focus on paid labour, the ecological critique targets Sen’s capability approach as a key inspiration of foundational thinking, arguing that a theory of human needs is better suited to conceptualise wellbeing within planetary boundaries. Based on this, we outline a novel schema of economic zones and discuss their differentiated contributions to the satisfaction of human needs. By privileging need satisfaction, such broadened foundational thinking demotes the tradable sector and rentier economy, thereby revaluating unpaid work as well as respecting ecological imperatives. This empowers new articulations of social and ecological struggles to improve living conditions in the short run, while having the potential in the long run to undermine capitalism from within.

Based on a Polanyi-inspired research program, we analyze urban transformations as interrelations between infrastructural configurations, i.e. context-dependent material infrastructures and their multi-scalar political-economic regulations, and socio-cultural modes of living. Describing different modes of infrastructure provisioning in Vienna between 1890 and today, we illustrate how political-economic processes of commodification and decommodification have co-evolved with socio-culturally specific modes of living, grounded in different classes and milieus. We show how, today, two modes of living—“traditional,” established during postwar welfare capitalism, and “liberal,” formed during neoliberal capitalism—co-exist. In the current conjuncture of rising inequality, neoliberal urban regeneration, and accelerating climate crisis, these modes of living are not only increasingly polarized and antagonistic, but also increasingly unable to satisfy needs and self-defined aspirations. Therefore, we explore the potential of social-ecological infrastructural configurations as an alliance-building project for a systemic social-ecological transformation, potentially linking different classes, social segments and forces around a common eco-social endeavor.

Today's ecological crises are entwined with inequality dynamics, yet prevailing techno-economic approaches in climate research and policy fall short in addressing the ecological crisis as distributional crisis. Recognising the limitations of techno-economism, focused on markets (price adjustments) and technology (efficiency gains), this contribution introduces sufficiency corridors as a concept, research field, and policy approach. Sufficiency corridors represent the space between a floor of meeting needs and a ceiling of ungeneralisable excess, i.e. within the sufficiency corridor everyone has enough (to satisfy needs) while no one has too much (to endanger planetary boundaries and need satisfaction). Establishing such corridors entails a process over time that continuously narrows the gap between floors and ceilings, lifting the former and pushing down the latter by strengthening forms of consumption and production that contribute to need satisfaction while shrinking those that do not. The article discusses the profound implications of this approach for how societal reality is reproduced and/or changed, highlighting the need for decisions that eliminate options between and within sectors and in the realms of consumption and production. After addressing questions of decision-making and the potential to realise corridors, the contribution concludes that the growing scientific consensus to complement techno-economic approaches with sufficiency measures remains inadequate. Instead, the possibility of a transformation by design hinges on embedding techno-economism within and subordinating it to a sufficiency framework.
