Rationalities and socio-spatial effects of hydraulic infrastructure in Sardinia. – The infrastructural processes of the water system unfold over extended periods, often resulting in nonlinearities within the processes themselves, despite originating as explicit projects aimed at material control over resources and territorial development. These constructions give rise to various interpretations of irrigation systems, intersectoral conflicts, and power struggles among the different actors involved in their management and use. The aim of this article is to engage in dialogue regarding the water infrastructure process in Sardinia, examining its intersection with the different rationales guiding water management and territorial development policies. It highlights both internal and external factors influencing these processes, as well as the significance of historical legacies.

Shadows of militarism on the city. An urban perspective on military geographies. – Cities represent a relevant perspective for analysing military discourses and practices. Firstly, because the urban scale continues to be the key site of conventional warfare and a space of experimentation for new forms of militarism. Secondly, because the presence and the resulting construction of military discourse determine a complex system that influences both everyday practices and the dynamics of governance. The analysis of these influences allows us to highlight points of overlap between processes of militarization and forms of urban violence (to be understood both in relation to individuals and in connection to the construction/limitation of spaces). This contribution, through an analytical dialogue between the literature on military geographies and urban studies, aims to examine the relationship between militarism at the urban scale and the geographies of violence, in cities not directly involved in war conflicts.

Biofuels and bioplastics between opportunities and opportunisms in a regional experience. – Global and European strategies on renewable energies increasingly highlight the need for a paradigm shift in socio-spatial relations in agriculture. The territoriality of the renewable energy supply chains re-proposes the top-down characteristics of the fossil fuels era, deferring the support to coherent initiatives linking energy and territorial systems. The contribution explores European biomass strategies and their effects on a territorial level in Sardinia. The EU and Italian government strategies aiming at consolidating bioenergy and bioplastic production, both in terms of regulatory regulation and financial incentives for production, are reviewed. Starting from the agriculture and biomass energy production literature and based on a series of interviews carried out between 2018 and 2020 with local stakeholders, the effects of policies are investigated. The energy production process from biomass in Sardinia and the internal and external variables connected to it are examined.

In this paper we suggest that, to approach the actual urban configurations, we are in need of new geographies. To critically understand the production of socio natural space we propose two methods: Planetary Urbanization and World Ecology. Consistent with the ongoing debate in Urban Political Ecology, we approach the Covid-19 pandemic as a result of the ecological crisis which is, as we show, an urban crisis. In order to immagine new methods of living with and
within nature, we suggest to go beyond the normative dichotomies developed by the Capitalistic culture. Considering this problem, we approac h to the urbanization as a multiscalar and uneven process, with a specific attention on public spaces (common), mobility (daily or wide ranging) and the relationship between infrastructures and nature (the Mapuche case).
