Agroecologia i sobirania alimentària a Catalunya ; alternatives al sistema alimentari globalitzat : un nou concepte agroecològic d’hort urbà

Abstract

The study analyzes the impacts of the globalized food system at a global level, conducting a more detailed examination of the situation in Catalonia and exploring viable alternatives to ensure a more sustainable and resilient model. The negative effects of the globalized model have been studied, including greenhouse gas emissions, biodiversity loss, and soil erosion, as well as the growing dependence on food imports, which creates significant vulnerability to global crises. In contrast, realistic alternatives have been sought to reduce the current impact on the planet. Agroecology emerges as a viable and necessary alternative to mitigate these effects and ensure a fairer and more sustainable food system. This model promotes crop diversification, reduces dependence on chemical inputs, and strengthens short food supply chains, supporting local farming and reducing the ecological footprint. Additionally, concrete initiatives have been analyzed that contribute to strengthening food sovereignty in Catalonia as well as in other countries. This study also examines the fundamental role of urban gardens, not only as food production spaces but also as tools to promote sustainability, social cohesion, and resilience to climate change. Furthermore, an innovative combination with mushroom cultivation is proposed, which could enhance the efficiency of these spaces and diversify food production in urban environments. The conclusions suggest that the transition to an agroecological model is key to achieving real food sovereignty and long-term sustainability. However, to accomplish this, public policies that support small-scale producers, better land-use planning, and a firm commitment to environmentally respectful production systems are essential
