- CLIMATE CHANGE & FOOD SECURITY
papers from a NATO Advanced Research Workshop, held in
conjunction with the Oxford Environment Conference
(Oxford, U.K., July 1993), are published in Global Environ.
Change, 4(1), Mar. 1994, and Food Policy, 19(2),
Apr. 1994. The papers summarized below are from the Global
Environ. Change issue, which focuses on the distributional
impacts of a changing climate and the different levels and
sources of vulnerability. Those in Food Policy (listed
here by title and author only) address the regional and global
context of future food security in a changing environment. Single
copies of these companion issues are available for £39 and £46
respectively (U.K.) or £41 and £48 (rest of the world) from

Change and World Food Security," R.S. Chen (CIESIN, 2250
Pierce Rd., Univ. Center MI 48710), R.W. Kates, 3-6. Introductory
Change and World Food Supply, Demand and Trade: Who Benefits, Who
Loses?" G. Fischer (Food & Agric. Project, IIASA, A-2361
Laxenburg, Austria), K. Frohberg et al., 7-23.
Summarizes findings of a major interdisciplinary research
project by scientists in 25 countries. Used crop models and
linked, national food system models to address socio-economic
impacts through the year 2060. In all scenarios considered,
relative agricultural productivity changes in favor of developed
Change and Agricultural Trade: Who Benefits, Who Loses?" J.
Reilly (Econ. Res. Serv., U.S. Dept. Agric., Washington, D.C.),
N. Hohmann, S. Kane, 24-36.
Finds that the direct impact of climate change on yield, the
global effect on commodity prices, and the export/import status
of a country determine the economic winners and losers. The high
degree of uncertainty should be a critical consideration in
Change and Social Vulnerability: Toward a Sociology and Geography
of Food Insecurity," H.G. Bohle (Inst. Cultural Geography,
Univ. Freiburg, Freiburg, Ger.), T.E. Downing, M.J. Watts, 37-48.
Uses a theory of the social vulnerability of food insecurity
based on explanations in human ecology, expanded entitlements and
political economy to describe the risk of exposure to harmful
perturbations, ability to cope with crises, and potential for
recovery. Illustrates with an example from Zimbabwe.
of Policies to Prevent Climate Change for Future Food
Security," N.J. Rosenberg (Pacific Northwest Lab., 901 D St.
SW, S. 900, Washington DC 20024), M.J. Scott, 49-62.
Speculates how the wide range of measures proposed to mitigate
climate change might differentially alter agriculture in
developed and developing countries, and how these changes might
affect food security. Measures that increase demands for water
and land pose the greatest threats to food security.
Change and Food Security: Agriculture, Health and Environmental
Research," V.W. Ruttan (Dept. Agric. & Appl. Econ.,
Univ. Minnesota, Minneapolis MN 55455), D.E. Bell, W.C. Clark,
Broadly interpreted, food security includes the income and
resources required to purchase a household's food and the health
required to use the food provided. To meet environmental changes
underway at the global level, more effective links must be made
among the agricultural, environmental and health sciences, and
between the suppliers of knowledge and technology and the users.
