Objective 2.02
• Compare the current and future issues in global agriculture.
Global outlook
• The world population will continue to grow with expectations
of 9 billion humans on the planet by 2050.
• More children survive to adulthood worldwide.
• More adults are living longer worldwide.
• Population growth will:
• Add stress to environmental systems of air, water, soil and natural
• Create challenges to meet demands for food and fiber.
Global outlook
• Examples of agriscience research to meet these demands:
• Genetically engineered crops
• a bio-engineered tomato that resists rotting
• New fuel sources
• biodiesel from animal fat
• Human nutrition
• decreasing the amount of animal fat in the diet and raising the
proportion of fat from vegetable sources
• Satellite technology (gps)
• determine various nutrient levels/deficiencies in plants
Trends and Issues in Global Agriculture
• 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
Examples of current/future agriculture
related issues
• Food Insecurity
• Global importance
• Defined as not knowing where a human will find their next meal
• the situation where people need to live with hunger and fear
• Food insecurity results from several factors
Climate issues
Urban development
Corrupt governments
Population growth
Oil price shifts
Examples of current/future agriculture
related issues
• Sustainability
• We must meet the needs of the present without compromising
the ability of future generations to meet their own needs
Examples of current/future agriculture
related issues
• Organic Food Production
• Crops are raised without using most conventional pesticides,
petroleum-based fertilizers, or sewage sludge-based fertilizers
• Animals must be fed organic feed and be given access to the
• Antibiotics and growth hormones may not be used in organic
• Accounts for more than 3% of all U.S. food sales
Examples of current/future agriculture
related issues
• GMO’s
• Genetically modified organisms
• Combing genes from different organisms results in an organism
being called genetically modified or transgenic
• Controversies surrounding this practice include safety, ethics,
labeling and others
• European countries will not purchase GMO foods from the US
• Fewer exports
Examples of current/future agriculture
related issues
• Local Food Movement
• Can be defined in terms of geographic proximity of producer to
• Is a very popular concept in regards to food safety, food
freshness, and reduction of environmental impact due to shorter
shipping distances
Examples of current/future agriculture
related issues
• CSA’s (Community Supported Agriculture)
• Direct-to-consumer programs
• Buy shares of a farms projected harvest
• Pay for their share of the harvest up front
• Distributes risk between the farmer and the consumers
• Pick up their share regularly in a communal location or the shares
are delivered directly
• USDA estimates as many as 2500 CSA’s are operating
Examples of current/future agriculture
related issues
• Water (quantity and quality)
• US water shortages are a major issue in the western portion of
the nation where expanding cities needs are competing with
farmers needs for the same water resources
• The aquifer that underlies Long Island represents the only
drinking water for the 3 million plus residents
• Southeastern US, including North Carolina, Water Wars have
become common place
• In Third World countries a safe water supply is a luxury
• Most areas of the world, supplies of safe water have become
generally insufficient because of misuse, poor management, waste,
pollution and climate change
