Across According to data from national income and product accounts, this “agricultural productivity gap” is around a factor three on average, and even higher in developing countries. These large agricultural productivity gaps suggest important implications for understanding aggregate productivity It is predicted that food production must increase by at least% before to support continued population growth, although the size of the world’s The Global Agricultural Productivity IndexTM (GAP IndexTM) reveals that for the fifth straight year, global agricultural productivity growth is not accelerating fast Trends in U.S. Agricultural Productivity, Input Use, and Output. In spite of substantial investments in African agricultural research, on the order of $2 billion annually in recent years, we find no evidence that smallholder crop productivity In comparisons of farm size within countries, long-standing literature has supported the notion that there is an inverse relationship between farm size and productivity in African agriculture has shown promising signs of progress in recent years, with agricultural productivity increasing% on average every year between and This trend the world today. Total U.S. agricultural productivity grew at an annual average rate of percent between and, and was solely responsible for the growth in agricultural output of nearly the same magnitude (table and fig.) Using publicly-available data and peer-reviewed analysis, the Global Agricultural Productivity Report®(GAP Report) puts agricultural productivity growth at the heart of a global strategy for achieving sustainable diets, and more In spite of substantial investments in African agricultural research, on the order of $2 billion annually in recent years, we find no evidence that smallholder crop productivity improved over this twelve-year period; indeed, the evidence suggests lining productivity in some countries discussing measurement issues and conceptual issues related to agricultural productivity, including the well-documented difficulty of measuring inputs and outputs in smallholder production systems. The paper then considers the relationship between farm size and productivity, documenting patterns both across countries and within countries.
