Sustainable Food Production
![Page 3: 11/13: Bellringer : Sustainable Ag Take out a piece of paper, title it, write the](https://reader035.vdocuments.site/reader035/viewer/2022062502/568163d8550346895dd529ad/html5/thumbnails/3.jpg)
Sustainable AgricultureSustainable agriculture: an integrated system of
plant and animal production practices having a site-specific application that will over the long-term:◦ Satisfy human food and fiber needs.◦ Enhance environmental quality and the natural resource
base upon which the agriculture economy depends.◦ Make the most efficient use of nonrenewable resources
and on-farm resources and integrate, where appropriate, natural biological cycles and controls.
◦ Sustain the economic viability of farm operations.◦ Enhance the quality of life for farmers and society as a
whole.

Sustainable Ag PracticesCrop rotation◦ Planting a series of different crops in
the same field over a period of yearsConservation Tillage (no-till)◦ Residues from previous year’s crops
are left in place to prevent soil erosionStrip Cropping◦ Alternating strips of different crops
along natural contoursTerracing◦ Creating terraces on steep slopes to
prevent erosion

Sustainable Ag PracticesShelter-belts (wind-breaks)◦ Row of trees planted to reduce wind
erosion of soilCover Crops◦Non-essential plant placed near the
crop to suppress weeds, add nutrients to the soil, and control pests/diseases
Polyculture◦ Growing multiple kinds of crops
Drip Irrigation◦ Irrigation pipes that use less water
and trickle water into the soil

Green Manure & FertilizersGreen manure comes from cover
crops which act as a living mulch. ◦ Examples: alfalfa, clover, hairy vetch,
winter wheat, clover◦ Helps with soil erosion, adds nutrients.
Natural fertilizers◦ Examples: organic compost, powdered
seaweed or kelp, mushroom compost◦ Amendment improves the quality of the
soil, drainage and structure, microbial activity, and increases plant nutrient availability

Sustainable PoultryCage-freeFree-rangePasture-raised
Poultry Benefits:◦Provide natural insect control◦Droppings enrich the soil◦Scratching aerates the soil
Sustainable practices can be applied with all domesticated animals.

Urban FarmsUrban agriculture is the practice
of cultivating, processing, and distributing food in or around a village, town, or city.◦ Popular in the Rust-belt cities:
Detroit, Chicago, Cleveland, Milwaukee (big Midwest Cities that used to be big steel cities)
◦ Detroit is the leader in Urban Agriculture. City Farm in Chicago
(Chicago Ave & N. Hudson)

Local FoodsLocavore: someone who is interested in eating
food that is locally produced, not moved long distances to market.◦USDA defines as within 400 miles of where it is grown.
Find local food online: http://www.localharvest.org/

Vertical FarmingCultivating plant or animal life
within skyscrapers, or on vertically inclined surfaces.◦Our living wall in the Aquaponics
Lab is a vertical garden.Maximizes crop output using
limited horizontal surface area.

Seasonal GrowingBuying and growing produce within the season
in which it is naturally intended to growRequired less pressure on resources, reduces to
need to grow items thousands a miles away and ship them

Farmer’s MarketsRetail markets featuring foods sold directly by
farmers to consumers.Provides fresh locally grown food and adds value
to communities.

Co-ops & CSAsfood cooperative (food co-op) is a grocery store
or organization collectively organized, run, and owned by members (consumers). ◦ Decisions are made by shareholders (members) so
cooperatives often exhibit a higher degree of social responsibility than corporations.
Community supported agriculture (CSA) food production and distribution system that directly connects farmers and consumers. ◦ Consumers typically buy "shares" in a farm's harvest in
advance.

ForagingForaging is searching for food
that grows naturally in the native environment (ex. morel mushroom hunting or picking weeds for a salad)
Goes back to the principles of hunting-gathering
Similar concepts have emerged for urban landscapes and people publish locations where you can find free food growing
