Biotic Constraints Diversity of species 50,000 edible; 15-50 used Traits Yield/productivity Taste, quality, appearance Phytonutrients Yield stabilization: GxExM Pest/disease resistance Nitrogen fixation Genomic selection Flood, salt tolerance Phenomics Systems/Synthetic Biology Efficiencies Feed-to-yield ratio Heat tolerance Photosynthesis: C3 to C4 Cisgenics vs Transgenics “Innate Potato” Water-use: Crop per Drop Nitrogen-, phosphorus-use Pre- and post-harvest losses
6
Abiotic Constraints Soil depletion GHGs and Climate Change: 17 to 32 percent of all GHGs

Portrait of global aerosols produced by a GEOS-5 simulation. Dust (red) is lifted from the surface, sea salt (blue) swirls inside cyclones, smoke (green) rises from fires, and sulfate particles (white) stream from volcanoes and fossil fuel emissions.

Abiotic Constraints Soil depletion GHGs and Climate Change: 17 to 32 percent of all GHGs Correlation between yield and temperature 4 o C increase: crop failures, malnutrition Livestock/aquatics responses

http://tinyurl.com/oh7679b http://tinyurl.com/q7otto6 Food Waste and Food Loss Double food production in 40 years Cut loss/waste by half? Cut water loss One quadrillion liters/year Impact climate change 1.4 kilograms (kg) CO 2 -eq capita −1 day −1 ; emissions of 33 million cars/year
20
Path Forward: Discoveries Virtual water and nitrogen Transformative approaches Gene editing Gene silencing FasTrack/DH Breeding Perennial/multi cropping Conversion of deserts? Algae in oceans? Bio-/nano-technology Synthetic biology Modern Meadow, Inc. o 3-D printing Army’s Natick Center o Lauren Oleksyk Logistics & mechanization Pest management Big data Policy research Partnerships Governments NGOs Private Academic Research investments
21
Path Forward: Farming systems Improved technologies Productivity Gap (Growth Rate/Year): 1.5 2% Cooperatives – Kibbutz? Closed loop systems Integrated/diversified Soil fertility Nitrogen, Phosphorus Sustainable intensification Policies & consequences Vertical farming Hydroponics Aquaponics Smart Farming “Internet of Agricultural Things” Robotics, sensors, sentinels UAVs Prescriptive Farming

21 st Century Farm http://tinyurl.com/o78mah9 Outcome of Big Data and Analytics 2014 National Corn Yield Average: 171 Bushels Randy Dowdy, farmer from Georgia: 503 Bushels Randy Dowdy used sensors, optimal varieties, irrigation and fertilizers, pest control, and Big Data analytics with the help of Monsanto and Climate Corp
23
Path Forward: Policies/Regulation/Marketing Governance Socially beneficial policies, programs Poverty reduction Education Trade – “glocalization” Jobs Environmental degradation/conservation
24
Humans Matter Consumers, businesses, groups, communities, towns, states and countries make decisions Information-dependent: Haves and Havenots Acceptance of technologies People impacts Technical, Policy, Regulatory, and Social Change Social Sciences Behavior, Choices, Attitudes Risk and Change Nexus of Bio-Physical and Social Sciences Advance science and integrate into society
