Scientific Communication 9 Billion Humans by 2050
Global Climate Change = Uncertainty
Increased Competition for Resources 3 Major Challenges on the Global Food Supply Increase
Total Cropland How do we feed the world without destroying it? Global Diet Modification Use Existing
Land More Efficiently Precision Agriculture "Farming by the inch" Uses GPS technology for data collection and geolocation Uses GIS software for map creation and data analysis http://www.globalmappinginc.com Global Positioning System (GPS) http://www.directionsmag.com/ Food & Agriculture Organization for the United Nations (FAO) 2005 (OECD Environmental Outlook to 2050) To feed 9 Billion... Global food production must increase
and nearly double in developing countries. 70% Currently, 24% of US corn is used for ethanol (Biomass Research & Development Center - BR&Di) Land Competition:
Food vs Fuel A system composed of hardware and software. Largely used to produce informative maps. Geographic Information Systems (GIS) Manipulation may be capturing, managing, analyzing and displaying. Geolocation of Data Characterization of Variability Implementation Precision Agriculture in 4 Steps Agriculture already uses an estimated: Most reliable and sustainable solution Decision-making Space-based radio navigation system http://www.no-tillfarmer.com/ Topography
Crop Yield Data
Nutrient & Pesticide Application Rates
Soil Properties What does precision agriculture bring to the table? Sustainability Expansion of agricultural
land likely to continue Will not solve problems alone,
but worth a shot Present Status of Precision Agriculture Developed World Developing World Determining Root-Cause of Yield Variability: Topography? Soil Properties? Weeds? Nutrients? Defining Management Zones "Variable-Rate Application" Most advanced and applied in North America and Europe
Research and development investment
Equipment is expensive
Lack of adequate decision support software Future of Precision Agriculture Research investments
Governmental and public support
Training of regional experts
Farm cooperatives Nascent stage, not much adoption
Fragmentation of small fields
Too expensive compared to land size
Lack of governmental support
No adequate infrastructure http://www.verifysustainability.com www.deere.com www.freshproduceconsultancy.com Why? Precision agriculture in developing countries is key to increasing global yields. Precision agriculture sustainably uses modern GPS, GIS and automation technology to cope with field variability to increase yields with decreasing inputs. Conclusion Questions? Increase Decrease Technological cost to farmers 68% of global arable land in developing countries Encourage precision agriculture adoption in developing countries Global Temperature Increase: 2°C
Atmospheric Carbon Dioxide: 550 ppm
Atmospheric Ozone: 60 ppb Predictions for 2050 (Food and Agriculture Organization) Bibliography ex: ESRI ArcGIS
MapInfo Urban populations will increase 72% - to 6.3 billion - by 2050 (United Nations 2011 World Urbanization Prospects) Major progress here is unlikely...

Roughly 1/3 of the food produced for human consumption is lost or wasted annually. (FAO Global Food Losses & Waste 2011) 40% of total land 70% of fresh water Why not?! (FAOSTAT 2012) McGill - Macdonald Campus Reported increases in crop yields of 60%-200% Cost Savings & Environmental Benefit in the form of decreased inputs Leaf color charts used in Asian rice fields have offered 20% saving in nitrogen used compared to farmer knowledge. Laser leveling of rice fields have led to 15-20% increase in crop yield. Economics of Precision Agriculture (Precision Agriculture Institute 2006) 80% of farmers who have adopted claim increased profitability Corn - $47.50 / ha
