GOOD MORNING!
Please get your interactive notebook and review for today’s quiz!
Please read the board!
SUSTAINABLE SUSTAINABLE AGRICULTUREAGRICULTUREHOW WOULD HOW WOULD YOUYOU EXPLAIN THE TERM EXPLAIN THE TERM “SUSTAINABLE”?“SUSTAINABLE”?
FOOD FORWARD! (24MIN)
SO WHAT ABOUT H-TOWN? How do people get to the sustainable food?
COMMUNITY GARDENS/URBAN AG (FF12:49)
VERMICOMPOST!
SUSTAINABILITY CONSIDERATIONS Processed food Transported food Stored food Monoculture Pesticides Inorganic Fertilizers Mechanization Short term gains Cost minimization
priority over human rights
Whole foods Local food Seasonal food Polyculture/polyvarietal IPM pest strategies Organic fertilizers People/animal
power Long term soil
fertility Fair trade = fair
wages for fair work
FARMER’S MARKETS (FF 5:16)
Houston: Rice Tues pm 3000 Richmond
Sat/Sun am St.Cyril on
Westheimer @beltway Wed pm
All $ directly to farmerAll local = all seasonalInteractions increaseOften organic, but not
certified
THE QUESTION OF ACCESS AND EQUITY 3,200 farmer’s
markets now take SNAP! (suplemental nutrition assistance program)
Farmer’s market food costs reflect a real wage for the farmer
EATING LOCALLY = EATING SEASONALLY
Most plants grow, produce food and then die at certain times of the year.
Houston crops NOW: Greens Green beans Squash Cabbage Oranges
SOLUTIONS?SOLUTIONS? Processed food Transported food Stored food Monoculture Pesticides Fertilizers Mechanization Few corporations control system Subsidies encourage unhealthy food Cost minimization priority over human rights
CSA’S – COMMUNITY SUPPORTED CSA’S – COMMUNITY SUPPORTED AGRICULTUREAGRICULTURE
Share holders pay annual fee; pick up produce regularly from central location (ff 15:50)

A SPECTRUM OF CHOICES – ALL GROWERS DEAL WITH PESTS!
Industrial Integrated Pest Organic/
Agriculture management traditional
Least sustainable most sustainable
*INTEGRATED PEST MANAGEMENT
Overarching philosophy: Elimination of pests is not possible, so the goal
must be pest suppression.
General practice: Watch pest populations. When there are too many, take action. Pesticides will be used only as a last resort.
GUIDING PRINCIPLE: PESTS AND DISEASES GENERALLY ARE PLANT-SPECIFIC. Examples –
Boll weevil attacks cotton plants
Rust and smut fungus attack corn
Yellow rust fungus attacks wheat
DIVERSITY PROTECTS HARVESTS FROM PESTS AND DISEASES BECAUSE THEY RUN OUT OF FOOD.
MONOCULTURES ARE LIKE A BANQUET!
CULTIVATION/PHYSICAL APPROACHES Crop rotation – non-legume, legume, fallow field/cover crop
EACH CROP DEMANDS A DIFFERENT MIX OF SOIL NUTRIENTS
Root/fruit/flowers: high Phosphorous demand (nucleic acids)
Leaves: Nitrogen (photosynthesis proteins)
CULTIVATION/PHYSICAL APPROACHES
Hedge rowsprovide shelter forbeneficial insects,
insectivorous birds and other pest predators (preying mantis, ladybugs, bats)
BIOLOGICAL PEST CONTROL
Release beneficial insects purchased in quantity (pest
predators), encourage
insectivorous birds
OTHER PREDATORS
INSECTIVOROUS BIRDS
CHEMICAL PEST CONTROL Pheromones: used in
bait traps to lure insects away from crops
CHEMICAL CONTROL As a last resort,
IPM farmers will use pesticides (herbicides, insecticides, rodenticides, fungicides)
DIRECTIONS: CUT OUT AND GLUE THE IPM STRATEGIES INTO THE CORRECT COLUMNS
Prevention strategies Response strategies

PRACTICE – WHICH IS MORE SUSTAINABLE AND WHY?
Potatoes bought at the grocery store vs. potatoes bought at a farmer’s market.
Homemade french fries vs. fast food french fries
Inorganic pesticide vs. crop rotation
