24. Behind the headlines on global hunger: Some conclusions World food prices are high and could keep rising –A spike-and-valley pattern is normal –Pressure for higher prices include grain users’ willingness to pay, especially for use as biofuels and as feed exporters’ willingness to cut their exports in times of scarcity –Potential for lower prices comes mainly from public investment in agricultural R&D and infrastructure World prices matter but other factors also influence nutrition –Income growth and direct interventions have helped many countries –Asia’s high levels of child underweight are slowly improving –Africa will also improve (slowly), through its long-delayed green revolution, and through slower but continued rural population growth
