From Dirt to DNA Agriscience Applications
2
What is Agriculture? Activities concerned with the production of plants and animals, and related supplies, services, mechanics, products, processing, and marketing.
3
What is Agriscience? The application of scientific principles and new technologies to agriculture.
4
Agriscience is…… An applied science because it uses principles learned in biology, chemistry, and physics (the basic sciences) in a practical way.
5
Examples of Applied Sciences
Agronomy Uses biology and chemistry to discover new ways to control weeds in crops. Entomology Uses biology and chemistry to study insect life. Agricultural Engineering Uses physics to develop new machinery. Saw Stop
6
Agriscience employs….. The scientific method to solve problems.
The steps to the scientific method are…. Identify the problem. Review literature. Form a hypothesis. Design the experiment. Collect the data. Draw conclusions. Prepare a written report.
7
Why is Agriculture/Agriscience Important?
Largest “employer” and the largest source of income in the United States and North Carolina. Twenty percent of all jobs in the U.S. are agriscience related. Projections show that the average size of farms in the U.S. will increase while the number of farms will decrease.
8
World Outlook The world population will grow as more people beget more people. More children are surviving to adulthood. More adults are living longer. Population growth will…. Add stress to environmental systems of air, water, soil, and natural resources. Create challenges to meet the demands for food and fiber (clothing and shelter).
9
Trends for Agriculture/Agriscience
Agriculture will always be an essential industry. Increased commercialization of agriculture will continue. New types of farming such as aquaculture (fish farming and farming the sea) will be used as well as traditional farming methods.
10
Trends for Agriculture/Agriscience
An expanded view of agriculture is necessary.

Global Agriculture: Trends & Issues
78
Global Outlook The world population will continue to grow
expectations of 9 billion humans on the planet by 2050 More children survive to adulthood More adults are living longer Population growth will: Add stress to environmental systems of air, water, soil and natural resources. Create challenges to meet demands for food and fiber.
79
How does Agriscience help?
Genetically engineered crops ie. a bio-engineered tomato that resists rotting New fuel sources ie. biodiesel from animal fat Human nutrition ie. decreasing the amount of animal fat in the diet and raising the proportion of fat from vegetable sources Satellite technology (gps) ie. to determine various nutrient levels/deficiencies in plants.
80
Agriculture will always be an essential industry.
Food is essential to life an iPad is not Clothing and shelter are basic needs of humans SmartPhones are not
81
Current Ag Issues Sustainability Food insecurity
Rests on the principle that we must meet the needs of the present generations without compromising future generations Food insecurity An issue of global importance. Defined as not knowing where a human will find their next meal. Due to: climate issues, urban development, corrupt governments, population growth and oil price shifts
82
Current Ag Issues Organic Food Production
raised without using most conventional pesticides, petroleum-based fertilizers, or sewage sludge-based fertilizers Organically raised animals must be fed organic feed and be given access to the outdoors. Antibiotics and growth hormones may not be used Organic sales account for more than 3% of all U.S. food sales. GMO’s (genetically modified organisms) Combing genes from different organisms results in a “transgenic” organism Controversies surrounding this practice include safety, ethics, labeling and others. European countries will not purchase GMO foods from the US resulting in fewer exports to these countries.
83
Current Ag Issues Local Food Movement
Geographic proximity of producer to consumer Very popular concept in the U.S. Food safety, food freshness, and reduction of environmental impact due to shorter shipping distances. CSA’s (Community Supported Agriculture) are direct-to-consumer programs in which consumers buy shares of a local farms projected harvest. Consumers often pay for their share of the harvest up front Participants pick up their share regularly USDA estimates as many as 2500 CSA’s are operating nationally.
84
Current Ag Issues Water quantity and quality
Shortages are a major issue in the western portion of the nation\ Expanding cities, such as Denver, are competing with farmers needs for the same diminishing water resources. In NY, the aquifer that underlies Long Island represents the only drinking water for the 3 million plus residents that use it. In the SE US, including NC, Water Wars have become common place. In Third World countries a safe water supply is a luxury. In most areas of the world, supplies of safe water have become generally insufficient because of misuse, poor management, waste, pollution and climate change.
