Sustainable Food Production Exploration of culinary art and food science What is a ______________________system? What is a sustainable food system? How does this apply to plant & ___________________ foods? What is the impact of food systems on the health of humans and the ___________________? How can we move away from eating ___________________? What are some practical consumer tips to eat sustainably Food Production: farming, gardening, ___________________, wild foods Harvest: powered equipment, farm, field, factory, ___________________, ocean, slaughterhouse Transformation, processing, packaging, labeling, marketing, heating/cooling Distribution, ___________________, warehousing, transportation Access, retailing, food safety net Purchasing, preparing, eating, waste ___________________ Can we produce enough? ___________________ between 1950 -1985, since then it has leveled off Africa, former Soviet Union and China seen biggest drops World produced enough food to meet basic needs, but still 1 in 8 do not get enough to meet nutritional needs Poverty, inequality, war, famine, ___________________ Food per person World average area per person = 0.30 hectares “Typical” grain yield = 3000 kg/ha This translates into 2.5 kg/person/day Average calorie content = approx. 2500KCal/kg This translates into 6250 Kcal/person/day More than enough! So what’s the problem? Increasing everywhere except sub-Saharan ___________________ Fastest growth: developed countries Why? 1. Slow ___________________ growth 2. Crop __________________ Under-nutrition UN Estimates: 5.5 ___________________ each year die prematurely due to effects of under nutrition. Each day 15,100 people --- 80% of which are children In U.S. estimates are 11 million do___________________have access to enough food Increasing World Crop Production ___________________and artificial selection Genetically ___________________ organisms (GMOs) Continued ___________________Revolution techniques Introducing ___________________ foods Working more ___________________ Genetic modifications Example: Citrus trees normally take 6 ___________________ to produce fruit yield in only 1 Rice crops that contain more protein or more ___________________or that can be grown with far less water Focus so far more on needs of ___________________countries vs. developing country needs ($) Can We Continue to Produce MORE Lack of resources such as ___________________, fertile soil and environmental factors may limit our ability to continue to yield more crops. Can we just spread the “___________________ ___________________” around the world to produce more? Will GE uniformity lead to more vulnerable crops to pests, diseases, harsh weather? The conventional food system Detriments The US food system is currently detrimental to the environment, human health, and future sustainability. Issues from: Use, loss, & ___________________ of land, soil, & H2O. The contribution to global warming from emission of green house gases (GHG). 1/3 GHG tied to the food supply. ___________________ fuel depletion. Loss of ___________________ fertility & nutrients for plants & animals. More ___________________ & animal diseases (infectious & chronic). Detrimental to Water, Energy, Land ___________________: plant and animal farming accounts for 70% of all water use by humanity; 90% in most developing countries. US food system uses ~80% of US fresh water. ___________________: US food system uses ~50% of US land area. Croplands, pastures, and rangelands are losing soil (overgrazing, tilling) at an unsustainable rate. It takes ~500 years to replace 1” of soil. ___________________: Fossil energy for fertilizers, machinery, irrigation, pesticides, transportation, etc. ___________________: Meat-based diet requires more energy, land, and water resources than the lactoovo or vegetarian diet. Animals: 20-80 fossil fuel calories per 1 food calorie Plants: 2 fossil fuel calories per 1 food calorie Plant proteins: 1/10th the fossil fuel use & carbon emission than animal proteins. Switching from meat to vegetables 1 day/week saves the equivalent of driving 1160 miles per year ___________________: Carnivores vs herbivores & farming vs wild caught
