Voices of Transition is a new documentary film with limited release but you can buy it online now! The film examines how we grow our food and ideas around how to make the whole agriculture system make more sense.
The film deals with community building, resilience and sustainability through urban farming. It draws on the experience of community and organic farming initiatives in France, the UK and Cuba and highlights how environmental and economic challenges to our current food system can be turned into positive stories, help create resilient communities, and to build a future in which soils and people once again support each other in a balanced and sustainable way.
Industrial agriculture is not kind to the environment and has been attributed to deforestation of the rainforest to the massive bee die-off. Yet, we find ourselves attached to this 20th century model of centralized production. Lucky for civilization, this is changing!
Small scale urban agriculture is getting large enough as an industry to compete with the large scale industrial production.
Urban agriculture in large cities goes a long way in redefining the food industry, he said. Piloted by Alvarez and fellow Humber College Graduate Craig Petten, Aqua Greens is trying to do just that with an innovative yearlong growing cycle. They use a process call â€œaquaponicsâ€ to produce basil, chives and arugula for restaurants and grocery stores around the Greater Toronto Area (GTA).
Aquaponics is a hybrid of hydroponics and aquaculture, Alvarez explains. Hydroponics refers to growing in soil-free mineral nutrient solutions, usually water; aquaculture describes the farming of fish and other water-based organisms. Aqua Greens uses a closed-loop ecosystem composed of both processes to grow their produce. Plant roots are placed in the tank that contains a fish called tilapia; water containing waste materials from the fish is absorbed by the plants, who use the waste as a sort of fertilizer. The water is then recycled back into the tank.
