Agriculture: Terms Agriculture is the deliberate effort to modify a portion of Earth’s surface through the cultivation of crops and the raising of livestock for sustenance or economic gain. “Cultivate” Any means “to care for. ” cultivated plant is called a “crop. ”

Earth: The Apple of Our Eye

Agriculture is IMPORTANT! Only about three percent of the Earth’s surface is capable of growing food. Over the past century, farming technology has made it possible to produce more food from the world’s limited cropland to feed the growing world’s population. However, much of this arable (farmland) land has been taken out of production for urban/suburban development and livestock grazing, or has been mismanaged leading to irreparable soil erosion. By 2030, we will need to produce 30 percent more grain to feed the expected population of 8. 2 billion. Protecting our arable land resources is becoming more important than ever. Food and Hunger 2008.

Some facts about farmland: In the U. S. , soil is now eroding at 17 times the rate at which it forms. The soil erosion rate is estimated to be double in Asia, Africa, and South America. In order to feed the nearly 80 million human added to the population annually, 12 million acres of new land must be put into production More than 25 million acres of productive arable land are severely degraded and abandoned worldwide every year – that’s an area the sixe of the states of Ohio, Indian, Illinois, Michigan, Wisconsin, and Minnesota put together.

Origin of Agriculture 1. Hunters & Gatherers 2. First Agricultural Revolution 3. Second Agricultural Revolution 4. Green Revolution

Hunters & Gatherers Facts Small groups, low population density Limited material culture No permanent settlements, nomadic Hunters Men Hunted animals or fished (20 -40% of food) Gathers Women Gathered nuts, berries, fruits, roots, plants, etc. (60 -80% of food) Today Isolated areas ¼ million people (0. 005% of world population)

First Agricultural Revolution Neolithic Revolution Agricultural Revolution that took place approximately 10, 000 years ago when human beings first domesticated plants and animals and no longer relied entirely on hunting and gathering.

Plant Domestication Root Crops (Vegetative Planting) Seed Crops Earliest More complex Cutting plants/dividing roots Cultivating seeds Cultivating roots Southeast Asia, Africa & South America Seed selection, sowing, watering, timed harvesting West India, Northern China & Ethiopia then to Near East & Europe

Animal Domestication Southwest Asia Goats (Zagros Mountains) = 10, 000 yrs ago Sheep (Anatolia) = 9, 500 yrs ago Pigs, cattle & dogs Reasons Ceremony Pets Scavengers Labor Food/milk Changes over time Animals change over time Protected from predators Chose more docile, smaller animals As animals bones get smaller = domestication
