Unit 5b Flashcards
Ecological Footprint
The measure of the area of land and water an individual, population, or activity requires to produce all of the resources consumed, and process the waste generated
What are examples of ecological footprint
- food eaten
- water used
- Energy used
- Clothing worn
- Housing and transportation
Carbon footprint
Differs from ecological footprint by being a measure of total carbon dioxide add other greenhouse gases house gas emissions released through activities both directly and indirectly by a person, country, or other entity.
Sustainability
Being able to use a resource or engage in an activity without jeopardizing the ability of future generations to engage in similar activities.
Sustainable Devleopment
Development that balances current human well-being and economic advancement with resource management for the benefit of future generations should be the goal
Maximum Sustainable Yeild
How much of a resource can be taken in order to continue harvesting it indefinitely
Maximum Sustainable Yeild
How much of a resource can be taken in order to continue harvesting it indefinitely
Crop Rotation
Is a planting strategy where different types of crop species are planted from season to season on the same plot of land.
Intercropping
Is a strategy allowing for space it crops growing at the same time to promote biological interactions
Natural Predators
Predators that occur naturally in the environment, and our ideals for IPM
Biocontrols
Allows biological factors to control agricultural pests
Sustainable Agricutlre
Fulfills the need for food and fiber while enhancing the quality of soil, minimizing the use of now-renewable resources, and allowing economic viability for farmers
Soil Conservation
Preventing soil erosion while increasing soil depth, and increasing nutrients and organic matter
Agroforestry
Vegetation planted as a windbreak to preempt wind and soil erosion
Strip Cropping
A from of intercropping that uses different spacing and rooting characteristics to prevent soil erosion
Contour Plowing
Plowing and harvesting parallel to the topographic contours of the land
Terracing
Farms shape sloping land into flat, step-like terraces
Perennial Plants
Plants that live or multiple years and do not need to be replanted each season
No Till agricutlre
Annual crop land that is not tilled or plowed in between seasons
Green Manure
Plant material grown with the intention of plowing it under a the end of the season
Use of limestone
Calcium carbonate sedimentary rock that has been grounded up or crushed to be used as a fertilizer
Rotational Grazing
Rotating farm animals to different pastures and fields so overgrazing doesn’t occur
Organic Agriculture
Production of crops to sustain or improve the soil. Without using synthetic pesticides or fertilizers
Reforestation
Restocking trees after clear-cutting allows for repopulation of the forest, erosion reduction, and starts to
