Since the 1990s, the food supply chain has become increasingly global and complex, with clear repercussions also in terms of the minimum standards and guarantees needed to protect the safety, and quality of food. At the same time, there has been an increased focus on the environmental sustainability of the food chain and on the consequences of climate change on food security. Aim of this paper is to discuss the fundamental aspects underlying the globalisation process of the agri-food system and the specific aspects related to food security, focusing on the measures for consumer protection and environmental sustainability introduced by the European Union. ; A partire dagli anni Novanta le filiere agroalimentari sono diventate sempre più globali e complesse, con evidenti ripercussioni anche in termini di standard e garanzie minime necessarie per tutelare la sicurezza, la salubrità e la qualità del cibo. Al tempo stesso, si è registrata una maggiore attenzione per la sostenibilità ambientale e le relazioni che intercorrono tra cambiamento climatico e sicurezza alimentare. Scopo di questa trattazione è di discutere alcuni aspetti fondamentali che sottostanno al processo di globalizzazione del sistema agroalimentare e degli aspetti specifici legati alla sicurezza alimentare, con particolare attenzione alle misure per la gestione del rischio alimentare e per la sostenibilità ambientale introdotte dall'Unione Europea.

The article explores the concept of civil society in connection with Web 2.0 and its transformative impact on society and politics, contrasting it with the earlier era of Web 1.0. Web 2.0, characterized by enhanced user interaction and content production, has given rise to a new media ecosystem that has reshaped the way people communicate, obtain information, and participate in the polity. The article highlights the emergence of popular social media platforms and how they have become integral to the platform society. These platforms have not only revolutionized online interactions but have also intersected with offline realms, including politics, commerce, and social relations. The article further explores the implications of Web 2.0 for civil society, contentious politics, and citizen engagement, examining the rise of protests, transnational movements, and the impact of digital resources on democracy and (digital) citizenship. Finally, the work discusses the potential of digital counter-democracy in the platform society and the need for democratic control in the digital age.
