Chapter 11 Feeding The World
Protecting soil
One layer of soil is humus. Humus is the organic component of soil, formed by the decomposition of leaves and other plant material by microorganisms
Features of Soil
No-till farming- leaving the soil undisturbed
Contour farming- planting crop around curves to reduce erosion Soil is more fertile
Siltation- The buildup of soil in an aquatic ecosystem
Shelter belt- a row of trees planted to help block wind
World Food Supply And Nutrition
The Green Revolution was a large increase in crop yields achieved by developing new varieties of plants. For example, wheat.
Dietary Needs
Carbs- Sugars
Calcium- Milk
Iron-meats, dark leaves
Protein-Eggs
Vitamin C- Fruits
Calories
Fats-Meat
Malnutrition is lack of proper nutrition, caused by not having enough of eat, not eating enough of the right things, or being unable to use the food that one does eat.
Leads to Anemia, over nutrition, and famine
Over nutrition- too much nutrition
Famine- Not enough nutrition
Not consuming enough fats, carbs, or protein
Around the world, there are people that must be fed. But what if our food sources runs out.
The industrialized production of livestock, poultry, fish, and crops is called industrial agriculture includes techno scientific, economic, and political methods.
Features of Industrialized Agriculture
11% Earth's land covered in land
In "plantation ag", crop yield is used. Crop yield is the size oh harvest from particular crop.
For grazing, posture is considered. Posture is lad used for livestock grazing
In industrialized agriculture, there is something called the dead zone. Dead zone is an area in the ocean where marine life can't survive
25% used for grazing
Few workers needed
Requires large amounts of water
Using fertilizers, pesticides, irrigation, and causing more waste
Using machinery that consumes energy
Most common i wealthy nations
"plantation ag" grows large amounts of single crop. For example, bananas, cocoa, and coffee
Plantation Agriculture is a large scale farm that only grows one crop and usually in tropical areas.
Feedlot is a small area where large numbers of livestock are raised
Rangeland is grass covered land that animals can graze on
Subsistence Agriculture is a type of farming where it's growing enough food to meet a family's immediate needs, even livestock. In subsistence agriculture, farm output is targeted to survival and is mostly for local requirements with little or no surplus trade.
Use the sun, own labor, and large animals. Large animals include draft animals. Also, with these large animals, they use domestication
Draft animals are large animals that are used to pull equipment
Domesticated is the bred for human life. Domestication for an animal and keep it as a pet or on a farm
You only make what you need
Subsistence Agriculture has a smaller impact on the environment
Subsistence Agriculture is practiced 3rd world countries and villages. For example, India practices this type of farming
Subsistence Agriculture
Subsistence agriculture is producing food without depriving future generations. For example, organic
The community is supported agriculture. It is a system where members pay farmers weekly
Shade is grown coffee. It is coffee grown in the shade of tropical trees. Reduce cutting trees
Farmers markets are where local farmers sell their produce
Fisheries
Different ways to get fishers is gill and drift nets. Also, by catch
Overfishing
By catch
Immature
Trawl net- long line dragged on ocean floor
Long line- lots of hooks
