There has been a resurgence of interest in the impacts of agricultural productivity on land use and the environment. At the center of this debate is the assertion that agricultural innovation is land sparing. However, numerous case studies and global empirical studies have found little evidence...

Global climate policy impacts on livestock, land use, livelihoods, and food security

Recent research has shed light on the cost-effective contribution that agriculture can make to global greenhouse gas abatement; however, the resulting impacts on agricultural production, pro- ducer livelihoods, and food security remain largely unexplored. This paper provides an integrated...

International trade buffers the impact of future irrigation shortfalls

There is increasing interest in the water–food nexus, especially the restrictive effect of water on food production in hot spots where irrigation stress is growing. However, little is known about the larger- scale implications of future irrigation shortfalls for global trade and economic...

Future property damage from flooding: sensitivities to economy and climate change

0.0 out of 5 stars

24 Jun 2016 | Contributor(s): Jing Liu, Thomas W. Herte, Noah S. Diffenbaugh, Michael S Delgado, Moetasim Ashfaq

Recent trends in the frequency and intensity of extreme weather events have raised the concern that climate change could increase flooding risks and property damage. However, a major challenge in attributing and projecting changes in disaster risk is that damage is influenced not only by the...

Climate adaptation as mitigation: the case of agricultural investments

0.0 out of 5 stars

24 Jun 2016 | Contributor(s): David B Lobell, Uris Lantz C Baldos, Thomas W Hertel

Successful adaptation of agriculture to ongoing climate changes would help to maintain productivity growth and thereby reduce pressure to bring new lands into agriculture. In this paper we investigate the potential co-benefits of adaptation in terms of the avoided emissions from land use...

Agricultural adaptation to climate change in rich and poor countries: Current modeling practice and potential for empirical contributions

0.0 out of 5 stars

24 Jun 2016 | Contributor(s): Thomas W. Herte, David B. Lobell

In this paper we discuss the scope of the adaptation challenge facing world agriculture in the coming decades. Due to rising temperatures throughout the tropics, pressures for adaptation will be greatest in some of the poorest parts of the world where the adaptive capacity is least abundant. We...

Debunking the 'new normal': Why world food prices are expected to resume their long run downward trend

0.0 out of 5 stars

24 Jun 2016 | Contributor(s): Uris Lantz C Baldos, Thomas W. 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...

Looking back to move forward on model validation: insights from a global model of agricultural land use

0.0 out of 5 stars

24 Jun 2016 | Contributor(s): Uris Lantz C Baldos, Thomas W Hertel

Global agricultural models are becoming indispensable in the debate over climate change impacts and mitigation policies. Therefore, it is becoming increasingly important to validate these models and identify critical areas for improvement. In this letter, we illustrate both the opportunities and...

Global food security in 2050: the role of agricultural productivity and climate change

0.0 out of 5 stars

24 Jun 2016 | Contributor(s): Uris Lantz C Baldos, Thomas W. Hertel

In this paper, we examine how the complexities introduced by trends in agricultural productivity and climate change affect the future of global food security. We use a partial equilibrium model of global agriculture incorporating a food security module that links changes in the average dietary...

Integrating HUBzero and iRODS: Geospatial Data Management for Collaborative Scientific Research (iRODS User Group Meeting, 2016)
