  13. 13. Conclusion•  Agriculture has an important role in mitigating GHG-emission•  Increased resource efficiency is one key element that at the same time reduce GHG and allows economic growth•  Targeted non-food biomass production may combine overall environmental protection with energy production•  Agricultural practice can be changed to ensure long term soil carbon sequestration•  The role of agriculture in climate change should be acknowledged and initiatives to support this role should be high on the agenda AGRICULTURE AND RURAL DEVELOPMENT DAY, DURBAN, SOUTH AFRICA 3RD DECEMBER 2011
