Exploring Food Production Systems: From Cropland to Oceans

Learn about food production systems worldwide, including crop land, rangeland, and oceans. Discover why food production has increased since the 1950s and the impact of 15 plants and 8 animals supplying 90% of the world's calories. Explore industrialized agriculture and traditional farming methods. Dive into the Green Revolution and growing techniques in traditional agriculture. Understand the difference between undernourishment and malnourishment and how micronutrient deficiencies can arise. Find out how to increase crop production through methods like crossbreeding, genetic engineering, and expanding the Green Revolution.

  1. CH 13 Food Production Sec 13. 1 I. Food Production (3 systems) 1. Crop land (76%) 2. Rangeland (17%) 3. Oceans (7%) Since the 1950’s food production has increased? Why?____ 15 plants and 8 animals supply 90% of world’s calories. 3 biggies in plant family? ____

  2. B. 2 major types of Food Production 1. Industrialized Ag or _____ (25% of all crop land)-mostly _______ countries. Uses lots of _________________. a. Plantation Ag-growing _____& occurs ____ 2. Traditional Ag (2 types) a. Traditional Subsistence Ag. (low input) uses no machines – just enough for family b. Traditional Intensive Ag.-use more ____ to grow for family and sell some See p 280 charts**

  3. II. Green Revolution (3 steps to increasing yield) 1. plant high yield monocultures ex__ 2. High Input 3. Use multiple cropping *Increased yields in ______ countries from 1950’s – 70’s. Why? _________ (called the 1st_________) *2nd green revolution = _______________________________ Pg. 282

  4. III. Case: Food Production in US – Agribusiness__!!! “Average food eaten travels 1300 miles” IV. Growing Techniques used in Traditional Ag. Interplanting=__ Why? (4 Types of Interplanting) 1. Polyvarietal cultivation -____ 2. Intercropping - ______ 3. Agroforestry/Alley cropping-________ 4. Polyculture –________ produced higher yields than high input. advantages:

  5. V. Food Production Undernurished-not enough____ -vs- Malnurishment-deficient in ____ ex. _____ Examples: marasmus and kwashiorkor Micronutrient defficiencies from: Overnutrition: 1 in 8 not fed b/c food not distributed equally? Why?

  6. How do you increase crop production: • Crossbreeding- • 2. Genetic Engineering (GMO’s)- • 3.Expand Green Revolution- • 4. Irrigate more land- • 5. Cultivate more land
