In response to population ageing and considerations of children's rights, age-friendly and child-friendly approaches share the idea that adapting the environment to vulnerable age groups benefits everyone. Their implementation, however, reveals two recurring limitations. The first is sectoral, since it designs interventions for single age groups and separates people who share spaces and relationships in everyday life. The second is one of scale, because it remains largely urban and struggles to reach inner areas, where ageing is faster and inadequate services. The study proposes the concept of an all-age intelligent territory, where the intelligence of a territory is measured by the quality of relationships and care between generations rather than by the quantity of technologies and services. The concept is examined through Smart Bakery Lab, an itinerant community baking workshop in the province of Cosenza (Southern Italy) that connected the provincial capital with its inner areas. The research combines questionnaires and in-depth interviews with 45 people, analysed thematically and through descriptive quantification. Where formal meeting places are lacking, community baking can work as an intergenerational social infrastructure, turning the co-presence of different ages into mutual learning, social capital and territorial networks. A paradox also emerges. In inner areas, intergenerational encounters are difficult but necessary. Depopulation has driven young people away from these areas. For this reason, they do not actively participate in these initiatives or take part as trainers rather than learners. Here, rather than offering services separated by age group, policies should rebuild the occasions for encounter between generations.

Posidonia oceanica (P. oceanica) is a key marine seagrass that provides essential ecosystem services but managing its stranded biomass (banquettes) poses a challenge to local authorities due to high disposal costs. This review examines the ecological and bioenergetic potential of P. Oceanica, focusing on the Calabria region. Through the analysis of regional monitoring data (ARPACAL) and a comprehensive review of the literature on anaerobic digestion (AD) processes, the study analyzes the transition from waste to resource. The results highlight a worrying regression of Calabrian meadows due to siltation and high burial-induced mortality. Chemically, the biomass is characterized by high recalcitrance (lignin > 34%) and an unbalanced C/N ratio (~153), which limits the efficiency of standard AD. However, the review demonstrates that acidic thermochemical pretreatment (132 °C with 0.4% HCl) can increase methane yields by up to 575%, while co-digestion with nitrogenous substrates further stabilizes the process. The study concludes that, although technical challenges such as reactor corrosion and sediment loss remain, the transformation of P. oceanica into biomethane represents a technologically potential route toward a circular Blue Economy, provided that operational and economic trade-offs are carefully balanced. Adopting the “Ecological Beach” model could enable sustainable coastal protection while unlocking prospective renewable energy potential.
