New cards
9

Fungicide

kills fungi

New cards
10

GMO's

New cards
11

Green Revolution

since 1950 increase in global food production by 88% due to high-intensive industrialized agriculture

New cards
12

Groundwater

the water that is beneath Earth's surface

New cards
13

Herbicide

substance that kills plants

New cards
14

IPM

Integrated Pest Management

New cards
15

Irrigation methods: drip

uses perforated hoses to release small amounts of water to plant roots (5% of water lost to evaporation and runoff, expensive)

New cards
16

irrigation methods: flood

flooding an agriculture field with water (20% of water lost to evaporation and runoff, can lead to waterlogging)

New cards
17

Irrigation methods: furrow

cutting furrows between crop rows and filling them with water. (inexpesive, abt 1/3 of water is lost to evaporation and runoff)

New cards
18

Irrigation methods: spray/overhead

pumping groundwater into spray nozzles across a agriculture field (1/4 of water lost to evaporation and runoff, more expensive, requires energy)

New cards
19

Meat production

raising cattle for human consumption. (increased fourfold between 1961 and 2007)

New cards
20

Pesticide

substance that kills rats, insects, bacteria, etc.

New cards
21

Rodenticide

Pesticide that kills, repels, controls rodents

New cards
22

Salinization

soil degradation process caused by adding irrigated water to dry places that leads to increase accumulation of salts in upper soil layers.

New cards
23

Slash and burn

burning small plots of land in tropical forests for a few years until nutrients are lost and then go to another area.

New cards
24

Strip cropping

Planting regular crops and close-growing plants in alternating rows to reduce depletion of soil nutrients.

New cards
25

Terracing

creating flat platforms in the hillside that provide a level planting surface, which reduces soil runoff from the slope.

New cards
26

Tilling

The turning-over of soil before planting.

New cards
27

Tragedy of the Commons

indiviuals will use shared resources in their own self intrest rather than in keeping the common good

New cards
28

Waterlogging

water accumulated underground and gradually rises water table

New cards
29

Windbreaks

Belts of trees along field edges to reduce wind erosion

New cards
30

Clearcutting

The process of cutting down all the trees in an area at once

New cards
31

Old growth forest

a forest that has never been logged

New cards
32

Second growth forest

a stand of trees resulting from secondary ecological succession

New cards
33

Selective Cutting

cutting down only some trees in a forest and leaving a mix of tree sizes and species behind

New cards
34

Strip cutting

clear-cutting a strip of trees leaving enough to allow natural regeneration
