GGR111H5 Lecture Notes - Lecture 12: Soil Fertility, Food Security, Agribusiness
Document Summary
What was the green revolution characteristics, mechanisms, issues. Capital requirements ( requires a lot of money) *poorer farmers pushed onto less fertile land because they cannot afford machinery (increase in famine and hunger = relates to carrying capacity) Soil erosion, salinization, contamination of water (moving trees causing more wind = soil erosion as topsoil is being harmed loss in soil fertility) It might be successful b/c it increased food supply but not a varity of foods in diet (no balance) No because a lot of food but no variety no balance. People losing rights to land and famine and deprivation and how are these systems culturally sustainable. Reduce time to slaughter (only work if food supply is increase) increase rapid tissue growth. Breeding of animals trait selection (some are able t produce meat and some are able to produce more meat) specialization beef, dairy etc. Housing of animals control feeding ( build up body tissue quickly) temperature light.
