1 Livelihood & Economy Primary Sector: Issues & Trends

2 Irrigation Environmental Issues Salt Disease Chemicals Waterlogging
Mitigation: proper chemical disposal

3 Environmental Issues Desertification Overfarming/grazing
Water erodes soil Arid Regions, esp. in Africa

4 Desertification, cont. Mitigation: vegetative Cover, H20 management
Reintroduce nutrients Ways to reduce Soil Erosion Terracing: less water erosion Fallowing: regeneration Crop Rotation: efficiency and vegetative cover

5 Environmental Issues Soil Degradation (More chemical than erosion)
Decline in soil quality=improper use Issues Loss of organic matter; less productive Effects of toxic chemicals and pollutants Mitigation Reintroduce nutrients

6 Deforestation Environmental Issues CO2 Levels Hurts plants & animals
Conservation/Mitigation Remove some, not all Replant/Reforestation

7 Environmental Issues Wetland Destruction
Wetlands protect various species and can even store storm water, preventing floods Drained for agricultural or urban use Hurts wildlife Conservation/Mitigation Restoration via flooding

8 Environmental Issues Reduction in Biodiversity
GMOs=a few crops; variety is lost Aquaculture Global demand; limited number Specialization Too much water used for irrigation Deforestation Wetland depletion Overgrazing Chemical fertilizers, pesticides, etc.

9 Environmental Issues River & Aquifer Depletion Too much used for agri.

10 Why do you think Certain areas deplete More groundwater Than others.

11 Environmental Issues Animal Wastes, Fertilizers, Pesticides Pollutes
Contaminates

12 Why do you think That these regions are More at risk for pesticide Contamination?

13 Sustainability Sustainability
Farming w/o negatively affecting humans or the environment Benefits Less fertilizers & pesticides Crop rotation Less antibiotics Manage animal waste Treat animals well

14 Debates Environmental Health Cultural

15 Debates GMOs Biotechnology

16 Organic Farming Debates Anti-Green Rev. No GMOs Expensive
Limited Supply Possibly contaminated w/o antibiotics Manure, Animal illnesses

17

18 Aquaculture Breeding fish Fastest growing agri. industry Issues
GMOs mating w/ non-GMOs (note that only some are GMO) Chemical and waste pollution Alien (non-native) species escaping Bigger fish eating smaller ones Mitigation Restocking farmed fish into the wild

19 What are some Environmental Dangers that you see In the picture?

20 Food-Choice Determines: Production Consumption

21 Food-Choice Organic Value-Added Specialty Crops/Food:
Some are willing to spend more $ on natural foods Value-Added Specialty Crops/Food: Changing a food item to add value Strawberries Jam Wheat Flour Goat Milk Soap

22 Food-Choice Fair Trade Developing countries must meet certain criteria
No child labor No GMOs Fair prices No hazardous chemicals Get fair wages and money for community development Consumers purchase makes a difference

23 Fair Trade Villages get developed, people are
Treated better, less health and environmental Issues.

24 Food Choice Local-Food Movements Freshness Helps the local economy
Know where the food comes from

25 Food-Processing Facilities
Markets Best location for consumption? Economies of Scale Where can it be mass-produced? Transportation Does the area have a good transportation infrastructure? Government Policies FDA regulations

26 Eliminating adulterated (contaminated) foods Proper labeling
Food Process., cont. Sanitation Storage Eliminating adulterated (contaminated) foods Proper labeling
