Al entender que la crisis civilizatoria encuentra raíces en la ruptura del vínculo político entre la humanidad, el alimento y los territorios, el siguiente artículo busca contribuir a una epistemología-política que sitúa la dimensión comunal como clave de la práctica democrática y el plano agroalimentario en un lugar central del ejercicio político inherente a la sostenibilidad de la trama de la vida humana y no humana.

Al concebir al capitalismo como un régimen ontológico que se halla en la raíz de la actual crisis ecológica y política, buscamos aquella praxis política contemporánea que contribuya a sanar el sociometabolismo entre humanos, alimentos y territorios. En ese camino, el siguiente ensayo propone aportar una epistemología política que concibe a la comunalidad como una clave crítica para el diseño de una ontología política que pueda hacer frente al capitaloceno.

Face aux échecs successifs des politiques climatiques et alors que l'objectif de rester en dessous du seuil de 1,5 °C s'éloigne de plus en plus, nous assistons également au danger d'un dévoiement complet de la prétendue « transition énergétique ». Obéissant aux intérêts d'un capital hautement concentré, en alliance avec les appareils d'État des principales puissances mondiales, l'expansion des « énergies renouvelables » devient le dispositif d'une nouvelle vague d'extractivisme. La course à l'exploitation du lithium ne contribue pas à atténuer la crise climatique, bien au contraire. Forme emblématique du néocolonialisme vert, elle relance le socio-métabolisme déjà sénile du capital. Son extraction à grande échelle menace d'extinction les systèmes hydro-communaux vivants dans les régions andines du nord-ouest de l'Argentine. Dans le bassin supérieur de l'Abaucán (à l'ouest de la province de Catamarca), l'exploitation du projet Tres Quebradas (sous le contrôle de la société internationale chinoise Zijin) entraîne de graves perturbations socio-métaboliques dans les systèmes hydriques, agricoles et alimentaires des communautés rurales du Bolsón de Fiambalá.

InnoWEE is a four-year project (from 2016 to 2020) financed by the European Community that involves ten partners from different European countries, as Greece, Italy, Belgium, Romania, Slovenia, Spain and Poland. The aim is to use the waste materials coming from construction and demolition processes of buildings and include them into a geopolymeric matrix with the purpose of producing prefabricated panels for different applications. Construction and demolition waste (CDW) materials with suitable characteristics have been selected to develop high performance geopolymeric panels for building walls envelopes and radiant panels for indoor walls and ceilings with low environmental impact. Field tests will be carried out in different sites in Europe characterized by different climatic conditions to check the simplicity of the installation procedure and the performance of the panels in terms of energy efficiency and environmental impact. ; This project has received funding from the European Union's Horizon 2020 research and innovation programme under grant agreement no 723916.

The relatively high installation costs for different types of shallow geothermal energy systems are obstacles that have lowered the impact of geothermal solutions in the renewable energy market. In order to reduce planning costs and obtain a lithological overview of geothermal potentials and drilling conditions, a pan-European geological overview map was created using freely accessible JRC (Joint Research Centre) data and ArcGIS software. JRC data were interpreted and merged together in order to collect information about the expenditure of installing geothermal systems in specific geological set-ups, and thereby select the most economic drilling technique. Within the four-year project of the European Union's Horizon 2020 Research and Innovation Program, which is known as "Cheap-GSHPs" (the Cheap and efficient application of reliable Ground Source Heat exchangers and Pumps), the most diffused lithologies and corresponding drilling costs were analyzed to provide a 1 km × 1 km raster with the required underground information. The final outline map should be valid throughout Europe, and should respect the INSPIRE (INfrastructure for SPatial InfoRmation in Europe) guidelines.
