With the project „Think global, eat local“ we wanted to encourage participants to re-think the global food system and our role as individuals in exercising our influence in creating more sustainable, secure and resilient systems of food production and distribution. We wanted to address active citizenship, not in terms of the political involvement of young people, moreover, we were focusing on a citizens’ participation within the sustainable development framework. We wanted to raise awareness among the young people about sustainable systems and help them understand sustainability as the product of a complex system, that starts with personal and collective attitudes. This project was addressing the following SDGs: Sustainable Development Goal 2 - End hunger, achieve food security and improved nutrition and promote sustainable agriculture and Sustainable Development Goal 12 - Ensure sustainable consumption and production patterns. During the project implementation, we have also included the SDG 11 - Make cities and human settlements inclusive, safe, resilient and sustainable (natural building techniques). Moreover, besides environmental and health issues, on the example of Almira in Spain, the world’s largest greenhouse complex, where poverty-stricken migrant workers face a battle for equality, we were also addressing social sustainability: human rights, discrimination and intolerance.
