  1. Producing Food and Green Revolution Dust Bowl By: David Castillo 6117502 Tyler Sanchez 0310787

  2. How Do We Produce Food? • Croplands grow mostly grains and produce 77% of the worlds food • Rangelands grow mostly meat and livestock and produce 16% of the worlds food • Ocean fisheries produce about 7% of the worlds food

  3. What Challenges Does This Bring About? • By 2050 we will have to produce more food than has ever been produced since agriculture began 10,000 years ago • Some people want to use genetic engineering by using the technology we have • Concerns of degradation, pollution, lack of water, overgrazing and overfishing

  4. Most Important Crops and Major types of Food Production • Wheat rice and corn provide more than one half of the calories people consume Major Types of Food Production include: • High input agriculture • Plantation agriculture, • Traditional subsistence agriculture • Traditional intensive agriculture

  5. Green Revolution • Since 1950 most of the increase in food production has come from increase in yield per unit of area 3 steps to Green Revolution • 1) Develop genetically engineered crops for high yield and plant them • 2)Use large inputs of fertilizer, pesticides, and water • 3) Increase the # of crops per year on each plot through multiple cropping

  6. 1st and 2nd Green Revolution • The 1st Green Revolution occurred from 1950-1970 in developed countries such as the United States. • The 2nd Green Revolution has occurred since 1967 to the present time in developing poorer countries.

  7. Industrial Food Production • Typically in the United States farming has become big business, this is referred to as agribusiness. • In agribusiness, one company takes over many acres in a centralized area and grows usually only one crop in order to make a huge profit. The advances in industrial technology such as packaging has made this phenomenon possible. • Food production generates 18% of our gross national income, 20% of our jobs, and the United States only has 3% of the entire worlds farm labor force.

  8. Techniques Used in Traditional Agriculture • Polyvarital Cultivation – Different types of the same species are planted on the same area of land. • Intercropping – plants of different species are planted at the same time in the same area. • Agro forestry – plants are planted in between rows of trees, the trees can also produce the harvested item themselves such as oranges. • Polyculture – when many different plants that mature at different times are planted together.

  9. Dust Bowl • The Dust Bowl took place in the 1930’s in Midwest America partly due to poor cultivation processes and a severe prolonged draught. • Monocultures hurt the soil here making it more susceptible to wind picking it up. • This era became known as the ‘dirty thirties’ and soil conservation efforts arose due to the impact this prolonged event had.

  10. Food Production, Nutrition, and Environmental Effects • Food production has begin to level off in recent times. • This brings about good and bad news. • The good news is that we are not continuing to exploit resources for food at a growing rate. • However the bad news is that there is a lot of malnutrition and starvation across the globe, and the problems we do cause by our need for food which include; overfishing, overgrazing, degradation of many ecosystems, high land use, extinction of species, and many other harmful effects.
