Theun Vellinga: Climate-Smart Dairy Webinar

  1. 1. Mitigation strategies for livestock in a global perspective Meeting on Climate Smart Agriculture Theun Vellinga, December 1, 2016

  6. 6. A dichotomy of the livestock sector Industrial, specialized §Commodity based §Optimising animal §Primary crops, good land §Trade-off to environment §Global sources, markets §High energy input §High CO2 profile Smallholder/backyard §Multifunctional §Optimising system §Crop residues, marginal land §Trade-off to animal §Local sources, markets §Low energy input §Low CO2 profile

  10. 10. Mitigation strategies
  11. 11. Mitigation in developing countries: 7 * F § Food security: a basic right! ● And prerequisite for development § Financial, market access, banking infrastructure § (Female) Farmers: knowledge transfer § Feed improvement: quality and availability § Fertilizer use: manure, synthetic fertilizers § The Fridge, the cold chain
  12. 12. Mitigation in industrialised countries § As CO2 is >30 % of the emissions: energy saving along the complete chain should be considered § Nitrogen Use Efficiency § Waste and waste utilization!
  13. 13. Conclusions § Ruminants! § Developing countries: ● Combine food security, adaptation and mitigation ● Existing knowledge, market access, institutional change, infrastructure § Industrialised systems: ● CO2 is a large fraction and should get more attention § Develop an approach to affect a diffuse sector ● Simple indicators ● It’s more than technology
