World agriculture ischangingrapidly Monthly average prices for wheat, maize and rice, Jan. 2000-Feb. 2011 Source: FAO Global Information and Early Warning System data (www.fao.org/giews/pricetool), downloaded Feb 20, 2011. All are monthly export prices, normalized to Jan. 2000=100, for US No. 2 Hard Red Winter Wheat, US No. 2 Yellow Maize, and Thai 100% Broken Rice.
Africa’s green revolutionishere USDA estimates of average cereal grain yields (mt/ha), 1960-2010 Source: Calculated from USDA , PS&D data (www.fas.usda.gov/psdonline), downloaded 7 Nov 2010. Results shown are each region’s total production per harvested area in barley, corn, millet, mixed grains, oats, rice, rye, sorghum and wheat.

Rural demography• Food policies• Farm technologies Africahad the world’sfastest and longestrural population growth Rural population growth rates by region, 1950-2030 Over 2% annual growth for 30 years!

Rural demography• Food policies• Farm technologies Conclusions #1: Africa’sdemographicturnaround • Africaisjustnowemergingfrom the world’smostextremedemographic transition, whichinvolved: • The world’sfastest rural population growth > 2,0 % for 30 years, 1960s-1980s • The world’sfastesturban population growth > 4,5 % for 50 years, 1950s-1990s • The worstdependency rates (children or the elderly) > 45 % for 60 years, 1950 – 2010 • These pressures are noweasing, steadilyopening new windows of opportunity
