Food Systems Food Systems: The value chain for food. From production, processing, packaging, consumption etc Agriculture: derived from latin agricultura- ager, "a field" cultura, "cultivation” Is agriculture wholly representative of the food system(s)?
Some Basic Working Facts Energy can be transformed. But it can not be created or destroyed. First law of thermodynamics - Principle on Conservation of Energy: (from potential to kinetic- heat/work) The smallest unit of matter: ATOM? Electron, neutron? What are we? A form of Energy?
Some Basic Working Facts States of Matter Solid State Liquid Gaseous % loss of energy at every conversion? What happens to the food that you eat? An apple? Is it possible to extract 100% of the energy from an apple? Seeds etc! Is the human = to an Ecosystem?
Some Basic Working Facts At a Systems Level Interdependent ecological systems regulate each other through the energy that they transmit from one level to another or from one system to another. -What if the system mutates? -Are humans mutated?
What is happening here? Where is the energy to propel this pyramid?
Disruptive Episodes on Ecosystems (DEEMS) Diverse systems maintain stable ecology and a balanced energy supply system. Linear systems are unstable, disruptive, distabilize other systems and have a poor energy balance with nature. Forests, Plantation, Farm?
How did people feed themselves in the old times? Was it sustainable? What has changed? What are the significant events that have lead to the "the breaking down of the complex food webs" into “the simple food chains”.
Disruptive Episodes on Ecosystems (DEEMS) Some triggers to the DEEMS Agriculture Innovations from war Fossil Fuel Transport System Quest for Efficiency- New Age
Disruptive Episodes on Ecosystems (DEEMS) -What are the other impacts?
Disruptive Episodes on Ecosystems (DEEMS): IMPACTS-Food Chain Systems (NOW) How did they come up with these figures? Is it good to export these kinds of foods? Water stress to other plants?
Disruptive Episodes on Ecosystems (DEEMS): IMPACTS How did they come up with these figures? Is it good to export these kinds of foods? Water stress to other plants?
Disruptive Episodes on Ecosystems (DEEMS): CASE The 12 largest flower firms with hundreds of hectares of flowers, fruit and vegetables in Kenya (Naivasha) supply supermarkets in European market. What are they actually exporting? One farm takes water normally available to more than 100,000 small holder farmers. What are the impacts?
Disruptive Episodes on Ecosystems (DEEMS): IMPACTS What drives this specific industry that does not only change the peoples landscape to sustainably grow their own food- but also destroy a whole ecosystems? Money? Politics? Psychological Manipulation?
Disruptive Episodes on Ecosystems (DEEMS): Solutions?
Disruptive Episodes on Ecosystems (DEEMS): The FUTURE Where do we want to be? How do we get there? Is it possible to re-engage with food webs as opposed to linear food chains? How will the 7+ billion get their food in the future? Design a food system for the future: that will meet all these challenges: Consider Policy+Infrastructure+Food Systems
