  3. 3. Agriculture the most important event in human history ‘The original biotechnology, fundamental to culture, health, quality environment & biodiversity.’
  4. 4. Agriculture is at the Center of Many of Society’s Most Important Debates Exciting time for Agriculture & Plant Breeding • Global food security •Enhanced productivity •Increased yield •Sustainable production • Water availability •Drought-tolerant crops • Biofuels •Yield technologies to help meet demand for both food and fuel • Global warming •CO2 footprint •Fertilizer use
  5. 5. Holistic Research “No matter how excellent the research done in one scientific discipline is, its application in isolation will have little positive effect on crop production. What is needed are venturesome scientists who can work across disciplines to produce appropriate technologies and who have the courage to make their case with political leaders to bring these advances to fruition. ” Norman E. Borlaug
