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

    08 Sep 2017 | Contributor(s): Tom Hertel, Uris Lantz C Baldos, Dominique van der Mensbrugghe

    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 | Contributor(s): Uris Lantz C Baldos, Tom Hertel

    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 | Contributor(s): Tom Hertel, Uris Lantz C Baldos

    Attaining the twin goals of food and environmental security in the coming decades poses a significant sustainability challenge. This paper examines the food and environmental security implications of a range of policies affecting the global food economy and terrestrial ecosystems, first in the...

  4. Land Use in the 21st Century: Contributing to the Global Public Good

    08 Sep 2017 | Contributor(s): Tom Hertel

    This paper focuses on the evolution of global public goods related to the world’s land resources over the course of the 21st century, their potential impacts on the world’s poorest households, as well as prospects for policy interventions aimed at enhancing these outcomes. It begins...

  5. The power and pain of market-based carbon policies: a global application to greenhouse gases from ruminant livestock production

    08 Sep 2017 | Contributor(s): Benjamin Henderson, Alla A Golub, Daniel Djauhari Pambudi, Tom Hertel, Cecile Godde, Mario Herrero, Oscar Cacho, Pierre J. Gerber

    The objectives of this research are to assess the greenhouse gas mitigation potential of carbon policies applied to the ruminant livestock sector [inclusive of the major ruminant species—cattle (Bos Taurus and Bos indicus), sheep (Ovis aries), and goats (Capra hircus)]— with...

  6. Economic impacts of climate change on agriculture: A comparison of process-based and statistical yield models

    07 Sep 2017 | Contributor(s): Frances C Moore, Uris Lantz C Baldos, Tom Hertel

    A large number of studies have been published examining the implications of climate change for agricultural productivity that, broadly speaking, can be divided into process-based modeling and statistical approaches. Despite a general perception that results from these methods differ...

  14. The role of international trade in managing food security risks from climate change

    20 Mar 2015 | Publications | Contributor(s): Uris Lantz C Baldos, Tom Hertel

    International trade plays an important role in facilitating global food security in the face of a changing climate. In considering this issue, it is useful to distinguish between two different time scales: inter-annual and inter-decadal. Inter-annual adjustments in international trade can play an...
