ENEC 201 Week 9 Notes: 10/17/16 - Economy in Kinston ruined by demise of tobacco o Woman moved back to Kinston and opened restaurant focusing on local food o Brought tourists back to Kinston and helped revitalize the economy While being sustainable - Growing urban-rural divide o Not a controversial topic (not divided among political parties) Somewhere where policy change can actually be made - Cons of GMO’s: o Ethics: humans playing role of God and altering species Especially important in Europe o Patenting: seeds controlled by few large seed companies o Uncertainty about safety: possible to accidentally move allergens from one plant to another - Uses of GMO technology: o Make land arable o Help farmers in third world o Herbicide resistant crops o Prevent small farmers from re-using seeds o Increase yields o Protect environment - CRISPR: allows DNA editing o Can create super-specimens o Can take genes from other plans/species and insert it into DNA of different/target plant o Successes: Variety of wheat for bread resistant to mildew Drought resistant corn and wheat varieties - Difference between GMO’s and GEC’s o One edits one species’ genes o One uses genes from other species - Microbes: beneficial in human gut, also relevant to agricultural systems o Lock in soil nutrients o Protect from pests - Artificial meat o Benefits: Smaller environmental footprint: less greenhouse gas emissions, less land use, less water use Gets around animal rights movement Doesn’t dicert food from human consumption No direct competition for resources - Urban agriculture: o Grow produce on rooftop gardens o Abandoned lots for growing crops o Vertical agriculture: can grow food indoors with LED lights, stacked for maximization of space LED lights more energy efficient, grow plants faster - Extend amount phosphate available to humans o Recycles human waste o Extract phosphate out of human waste and put it back inot environment o Could work well with urban agriculture Gives full circle - Aquaponics: plants not growing in soil o More adaptable to location - Precision agriculture: o Capital intensive agriculture o Use sensors, drones, etc. to pinpoint need for fertilizers/pesticides/herbicides Reduces need for chemical use Can also limit water use - Labor intensive technology o Must be sophisticated to work well o Try to mimic natural ecosystem o Ex. Wet rice Rice not always grown underwater But leads to highly increased yields Can add people and continue to produce more food without sacrificing employment Increased amount of labor increases cooperation/coordination better/more efficient system Ecosystem of wet rice: marshy, wet, flooded, humid Mimic ecosystem by adding/integrating: Fish Water fowl Algae as food for water fowl and fish Helps rice grow too
