Big Data and the Productivity Challenge for Wine Grapes Nick Dokoozlian Agricultural Outlook Forum February 20160 Big Data and the Productivity Challenge for Wine Grapes Outline • Current production challenges • Lessons learned from annual crops • How will we utilize Big Data to meet our challenges? – Measure – Model – Manage • Summary 1 The Productivity Challenge for Wine Grapes • Suitable land, labor and water for agriculture are becoming more scarce and expensive • Need to increase grape supply without increasing production area and environmental impact • Must increase both yield and quality simultaneously • Similar challenges are faced by nearly all agricultural commodities worldwide 2 How are annual crops addressing these challenges? Dramatic increases in the productivity of agronomic crops have been achieved during the past century via: • Genetics – traditional breeding and genomics • Improved agronomic practices and resource management • Application of remote sensing and other technologies 3 How are perennial crops different in their approach? Progress has been much slower in wine grapes and other perennial crops: • Critical mass – limited acres = limited attention despite farm-gate value • Genetics – research, breeding cycle and market tradition • Production cycle and innovation adoption • Yield – quality relationships 4 IntegratedObjective systems of Today’s are required Meeting for improving productivity and quality Germplasm Systems Precision Improvement Biology Agriculture • Clonal • Elucidate the • Characterize the selection regulation of parameters • Cultivar and key yield and regulating vine rootstock fruit quality productivity and improvement pathways quality via traditional • Functional • Model key breeding genomics – relationships • Pest/disease linking genes • Variable rate resistance to key traits management 5 IntegratedObjective systems of Today’s are required Meeting for improving productivity and quality Germplasm Systems Precision Improvement Biology Agriculture • Clonal • Elucidate the • Characterize the selection regulation of parameters • Cultivar and key yield and regulating vine rootstock fruit quality productivity and improvement pathways quality via traditional • Functional • Model key breeding genomics – relationships • Pest/disease linking genes • Variable rate resistance to key traits management 6 The Future of Grape Growing MEASURE Measures Automated sensors used to measuring intra- construct field variability – geospatial crop load, canopy maps of key size, irrigation relationships requirements MANAGE MODEL Information used to spatially alter cultural practices 7 Historical sensors are site specific Historical soil measures X X X 9 Sensors provide high density soil information 10 High Resolution Maps - EM Sensor Characterizing Yield Variability 12 13 Why does variability matter?
