Ecological footprint in citys is increasing due to the pressures of over population, one of the most significant facts that contributes to this situation is the need for food, which involves natural resources consumption and waste generation. Farming activities require large extensions of land, water consumption, and the use of fertilizers; in the other hand, food processing activities implies transportation, refrigeration, plastic and paper consumption for packing, inter alia. Becomes clear then that the food system is a pretty energy and material intense activity, and this is why it is necessary to start thinking about bringing back food production in a small and local scale.
Global concern about climate change is also forcing to the production system to adopt new logistics for transportation, where the GHG emissions could be diminished, or even disappear.
New proposals for implementing urban agriculture systems, based on strategies outside the BAU model, like bio Economy, and circular economy, emerge as the most accurate answers for this situation. By using this approach, cities are not only increasing their food security, but also it is going to contribute to maintain and preserve tradition and culture.
Latin American cities are under severe processes of uncontrolled urbanization, people come to the city looking for a better opportunity of life, but they settle on high risk zones, where the probability of a landslide is high. Difficult access, and poor security conditions triggers in a lack of access to a basic diet for the most vulnerable people. This work analizes how by combining the implementation of sustainable agriculture on the hillside, and the transformation of food in a closed loop, cities will be not only ensuring food security, but also are going to be more resilient, and prepared for a low energy future.
