    1. 1. Food, Nutrition and Environmental Issues XNB151 Food and Nutrition
    2. 2. Pre-swallowing vs post- swallowing Agricultural Geography practice Climate Hygiene, Cuisine Religion contamination, food safety SEP Marital Age Finances status Pregnancy Smoking/ Cooking skills Cuisine Medical alcohol TasteAccess/ conditions consumption preferencestransport/ Workavailability Gender Weight goals Civil war Gender Athlete/ Mental illness Water activity level Hormones Government Upbringing/ regulations family values Household Government structure regulation Shelter Equipment
    3. 3. What do we need to grow food? Technology Naturally occurring plants & animals Labour Machinery Air Sunlight Food Warmth Land Water Fertiliser Capital Soils & nutrients Energy
    4. 4. Effect of Food & Nutrition on the Environment Nutrition requirementsMistreatment of animals Carbon emissions Land degradation & soil erosion Climate change Increases in water Loss of biodiversity Loss of species usage
    5. 5. Effect of the Environment on Food & NutritionEnvironmental change  impact on ‘primary’ & ‘secondary’ resourcesLand degradation Temperature Water scarcityFood insecurity Food production Food safety http://www.youtube.com/watch?v=Uf8AOXc6_fg http://www.youtube.com/watch?v=GXaX2m2Yc-U http://www.youtube.com/watch?v=1H9WZGKQeYg
    6. 6. Sustainability of Agricultural Systems• The population has grown exponentially• The maximum population the earth can support depends on the ability to feed the population requiring an omnivorous diet• Climate change could compromise this ability• Climactic disasters & disease/pest outbreaks could serve to limit the population
    7. 7. Phosphorus• Chemical element required by plants for growth• Current serious threat to agriculture and food production is increasing shortage of phosphorus – Estimates suggest supplies may only last 15 – 25 years THERE CAN BE NO CELLULAR LIFE WITHOUT PHOSPHORUS http://www.youtube.com/watch?v=VHvsQXSEbQQ
    8. 8. What can we do?• Sustainable agricultural practice – Efficient use of water (irrigation practices) – Widespread use of machinery – GM crops – Sufficient fertiliser – Environmentally safe pesticides – Technologies to increase yield & efficiency
    9. 9. ‘Globesity’ Obesity and climate change both increase in association withimproved technology, less labour intensive work and carbon-intensive foods
    10. 10. Shared determinants between climate change and nutritional problemsEnvironmental Nutrition Problems Problems
    11. 11. % Obesity CO2 Tonnes /capita 2004
    12. 12. Obesogenic environments• “An environment that promotes gaining weight and one that is not conducive to weight loss” – Swinburne, 2009• Effect on individual nutrition and nutrition status
    13. 13. Food insecurity 24-hour food retail outletsHigh density of ‘unhealthy’ food retail outlets High-population density Obesogenic environment Poor conditions/ opportunity for Low-cost of energy dense physical activity convenience foods Technological improvements http://www.youtube.com/watch?v=A6QnCdc6LkY
