Hungry for Change - Tim Benton

  1. 1. Biodiversity matters Tim Benton, UK Champion for Global Food Security and Professor of Population Ecology 10 November 2011
  2. 2. Biodiversity is important
  3. 3. Production needs to grow PPPs important to reduce losses % Pre-harvest crop losses due to pests and diseases worldwide (Oerke, 2006) Wheat Maize Rice Potatoes 0 -5 Percentage loss of crop -10 -15 -20 -25 -30 -35 -40 -45
  4. 4. Minimise (unwanted) ecological impacts • Better chemical targeting – Specificity of action – Need for new products that are pest specific and minimise indirect and persistent effects • Work with the environment – Enhance natural pest control – Ensure proper use: keep PPPs away from crops
