Developing Life Cycle Inventory Data for Science-Based Strawberry Production Susutainability Metrics

  1. 1. Developing Life Cycle Inventory Data for Science-Based Strawberry Production Sustainability Metrics Presenter Ezra Kahn USDA- National Agricultural Library Knowledge Services Division Principal Investigator: Ganti S. Murthy Associate Professor, Biological and Ecological Engineering Oregon State University
  2. 2. The Team Project Team • Ganti Murthy- PI, OSU • S.M. Hossein Tabatabaie- Graduate Student- OSU • Peter Arbuckle- USDA-NAL • Ezra Kahn- USDA-NAL • Susan McCarthy- USDA NAL • Ashley Loneman- Contract research Project Advisory Group • Kathy Demchak- Penn State University • Jayson Harper- Penn State University • Dan Legard- California Strawberry Commission • Joyce Cooper- University of Washington
  3. 3. Objectives Develop “meaningful and constructive metrics for strawberry production sustainability.” • Develop unit process/life-cycle inventory data for U.S. strawberry production – Demonstrate the use of crop budgets for LCIs • Propose sustainability metrics • Peer review results • Release results publicly through USDA LCA Commons
  4. 4. Project Deliverables Deliverable Task/Month Quarterly progress reports Quarterly Peer reviewed LCA extended crop budgets Task 3/June Automated software tool to convert excel-based LCI data from crop budgets to common global LCI format Task 4/June Peer reviewed life-cycle inventories made publically available through USDA-NAL LCA Commons. Task 4/June Final report with LCA results and sustainability metrics Task 7/June Project video and public relations products TBD
  5. 5. Project Status • Project results currently in peer review • Sustainability metrics proposed, work still in progress • Use peer review to improve methods and results
  6. 6. Peer Review Panel – Dr. Marvin Pritts (Cornell U., Dept. of Horticulture) – Kathy Demchak (Penn State U.) – Karen Klonsky (UC Davis, Agricultural and Resource Economics) – Dr. Bielinski Santos (U of Florida, Gulf Coast Research and Education Center) – Dr. Barclay Poling (N. Carolina State U., Department of Horticulture Science) – Dr. Oleg Daugovish (UC Cooperative Extension Ventura County) – Curt Gaines (UC Davis) – Tom Sjulin (Driscoll Strawberry Associates) – Ted Campbell (Florida Strawberry Growers Association)
  7. 7. Cradle to gate life cycle analysis California, Florida and North Carolina Plasticulture Functional Unit: 1 kg ripe strawberry
  8. 8. Cradle to gate life cycle analysis System Boundaries California, Florida and North Carolina Plasticulture Functional Unit: 1 kg ripe strawberry
  9. 9. LCA results (under review): Impact contribution -- California -40 -20 0 20 40 60 80 100 120 140 Materials Agricultural Machinery Fertilizers Chemicals Fuels
  10. 10. Project Results: Life Cycle Inventory Data Collection – LCA Extended Enterprise Budget excel sheet • Collected primary data from 3 producers • Published Enterprise budget sheets Unit Operations Resource Category Name Remark Name Field Preparation Only Establishment year Prime Movers Planting Operations Farm Machinery Analysis/Assessment All years Fuels Cultivation/Weeding Fertilizers Irrigation Fixed Expenses Nutrient Application Only production years Pesticides Harvesting Herbicides Post-Harvest operations Insecticides Transportation Fungicides Fixed Expenses All years Materials Labor Water Yield
  11. 11. Findings: Life Cycle Inventory Data Collection – LCA Extended Enterprise Budget excel sheet • Generated LCA unit processes • Challenges for data collection: – Inflexible to user inputs – Communicating LCA terminology to Ag Economists – Inconsistent data among states • Statistical representation vs. expert judgement • Planning vs. historical representation – Nursery process not included – Expertise in LCA and Strawberry production still necessary
  12. 12. Strawberry metrics • Strawberry Fossil Energy productivity (SFEP) and strawberry phosphorous productivity (SPP) can be defines as follow:
