PRESENTATION OUTLINE
TECHNOLOGIES: AGRICULTURE
Agriculture is the science and practice of using the soil, producing crops, and raising livestock. Agriculture is the basis of civilization. Agriculture is the food that we eat, the clothing we wear, and the material of our homes.
Agriculture also includes:
-the financing, marketing, and distribution of agricultural products
-farm production supply and service industries
-nutrition and food consumption
- the use of land and water resources
-development and maintenance of recreational resources
-economic, political, environmental and cultural characteristics of the food and fiber system.
Some of the products we use everyday come from agriculture, such as health care, construction, manufacturing, education, and personal care products.
how agriculture changed NORTH AMERICA
In the United States, the cotton gin was invented by Eli Whitney in 1794, this reduced the time needed to separate cotton fiber from seed. The new technology helped the farmers of the southern United States pick cotton faster which made them save money by not needing as many slaves, and made them money because they could sell it quicker. So, it was a big economic boost.
how agriculture changed SOUTH AMERICA
A German based nongovernmental organization has developed fog collectors in Peru to help communities in dry climates capture water. They do this by setting up screens on foggy hilltops, and the screens absorb the moisture from the fog into water droplets that are funneled into water tanks. This changed the area, and other areas because usually dry climates are now getting water for farming.
how agriculture changed EUROPE
An important development was an improved horse-drawn seed drill invented by Jethro Tull in England. Until then, farmers planted seeds by hand. Tull’s drill made rows of holes for the seeds. By the end of the 18th century, seed drilling was practiced in most of Europe. This brought change because it helped farmers plant seeds faster.
HOW AGRICULTURE CHANGED ASIA
The molecular breeding technology system was established in China, and a group of high-level new crop varieties were cultivated. Bill Niebur (the manager of this system) said, "with cutting-edge molecular breeding technologies" they can "enhance and accelerate maize breeding in China." Maize is another name for corn.
how agriculture changed AFRICA
Small-scale irrigation is being used in Africa, and it is helping the farmers. For example, in Zambia, smallholders who were able to cultivate vegetables in the dry season earned 35% more than those who do not. The systems used for small-scale irrigation, such as pumps and on-farm ponds, are cheap, and can allow farmers to grow crops all year-round instead of just the times it rains. This also allows farmers to grow high-value crops. This technology helps farmers sell more produce at a higher costs.
HOW AGRICULTURE CHANGED Australia
In 1837 to 1919 the invention of the stump-jump plough in the 1870s by Richard Bowyer Smith made it possible to crop large areas of the mallee scrub country. The invention was used all over Southern Australia, and in to previously unfarmed country.
