  1. Predicting Long Term Food Demand, Cropland Use and Prices

    08 Sep 2017

    This paper seeks to survey, understand and reconcile the widely divergent estimates of long run global crop output, land use and price projections in the current literature. We begin by reviewing the history of such projections and the different models and assumptions used in these exercises. We...

  2. Debunking the 'New Normal': Why World Food Prices are Expected to Resume their Long run Downward Trend

    08 Sep 2017

    Contrary to the opinions expressed by many commentators, the recent episode of higher prices for agricultural commodities is likely a transitory phenomenon. When compared to the last half-century, population growth is expected to be much slower in the coming decades, with nearly all of the growth...

  3. Attaining Food and Environmental Security in an Era of Globalization

    08 Sep 2017
