• FAO 815 million people undernourished
• 777 million in developing countries of which 504 million from Asia
• 25,000 people die every day from hunger
• World Food Summit (1996) and MDG (2000) goal reduce by 50% by 2015
• Need to reduce by 22 million/yr c.f. current rate only 6 million/yr

3. Water
Challenges AheadChallenges Ahead
• Irrigation water use efficiency generally low : 20 % (paddy) to 90 % drip
• Average for developing countries ~43 % • Need improvement in water productivity
water efficiency & higher crop yields • Use of lower quality water• To meet 2025 food production levels
need ~ 2,000 cubic km additional water • 2030 water withdrawals for irrigation in
developing countries 14 % increase • Chronic competition for water expected

Challenges FacedChallenges Faced
• More disposal income Change in diet, more consumption of meat
• Developed countries 70-100 kg/p/yr c.f. < 20 kg/p/yr in developing countries
• Developing world catching up
• Need to increase cereal production 1.84 b tons 2.8 b tons by 2030 [50 % food, 44 % feed]
