Published on

Presented by Ridha Ibidhi on May 9, 2019, as part of the first CCAFS & GRA CLIFF-GRADS Webinar Series. See the Introduction for more details: 2019 CLIFF-GRADS Webinar Series - Using modeling, life cycle assessment, and trade-off analysis to understand low emissions development options.

  • Works For Teens! Hey, I'm only 18 and I thought I was going to have small boobs forever. After using your book for about 2 weeks, I started seeing results! I then used it for another month and I managed to get my breasts up to a C cup (with padding). I'm so pleased and I'm getting a lot more attention from boys now! Thanks you ▲▲▲

Optimising environmental efficiency of dairy intensification strategies for delivery of milk and beef in Costa Rica

  1. 1. Name: Ridha Ibidhi Host Institution: Bangor University Optimising environmental efficiency of dairy intensification strategies for delivery of milk and beef in Costa Rica
  2. 2. Purpose of research Carbon neutral by 2021 Low productivity pasture livestock production Deforestation Climate change Environmental challenges Milk production: 11.7% of the added value of the agricultural sector.
  3. 3. Purpose of research  Calculate the milk footprints for alternative dairy systems and intensification strategies (conventional and attributional LCA approach).  Apply CLCA to scenarios of milk production shifting from one type of dairy system to another, to support conclusions about the respective efficiency of different dairy intensification strategies.
  4. 4. VAMPP dataset Veterinary Automated Management and Production control Program (18000 farms) Ministry of Agriculture and Livestock (920 farms) MAG dataset 1. Data Source Research methods
  5. 5. Research methods The Dairy and Beef Life Cycle Assessment tool Key performance indicators:  Global warming potential: Kg CO2e: CO2, N2O, CH4  Eutrophication potential: Kg PO4e: P & N water, NH3, NOX  Acidification potential: Kg SO2e: NH3, NOX, SO2  Water use potential (WF): H2Oe
  6. 6. Research methods Intensification scenarios: Assess the overall environmental efficiency of different breeding strategies to either: - Minimize lactations - Maximize number of lactations - Increase longevity of lactations. Comparing the environmental footprints of milk using the LCA tool of animals with: - Many lactations (7,8,9,10,11) - Long lactations (12,14,16,17,18 months)
  7. 7. Results Classification of dairy farms in Costa Rica: 1. Large breed intensive dairy farms (Holstein) 2. Small breed intensive dairy farms (Jersey) 3. Double purpose farms (Bos Indicus) 4. Suckler-beef farms (Braham) 5. Double purpose fattening farms (Bos Indicus) 6. Suckler fattening farms (Braham)
  8. 8. Results • LCA results: ongoing….. • Expected results: Identify the most environmental efficient breeding scenarios: towards a sustainable milk production. • Identify possibility of shifting from one type of milk production to another system more efficient environmentally and economically.
  9. 9. Conclusions  Take advantage from the Bangor experience in consequential-LCA of dairy systems. A real application of the LCA tool on the Costa Rican dairy systems which is the project of a research paper.
  10. 10. Advices to future CLIFF-GRADS students • Take the maximum advantages from the expertise of the host researchers in the GHG field (workshops, meeting, reported, support materials, E-learning courses....). • Set a networking with other doctoral students and researchers in the host institution. • Working in one of the most prestigious research centers on LCA analysis, being supervised by leading scientists in the subject and collaborating with them in scientific publications is extremely important.
