This study by IFPRI was conducted to determine the impact on world prices, agricultural commodities production, and food security and nutrition of raising the annual growth in agricultural total factor productivity (TFP) from the current estimate of 1.6 percent to 2 percent by 2030 through investment in agricultural research and development (R&D). The study also compared three R&D investment strategies: (1) gradual TFP increase, (2) accelerated TFP increase, and (3) developing-countries-only TFP increase. »
