OF GENERAL INTEREST: GENERAL AND POLICY
WarmingThe Role of Rice," H.-U. Neue (Intl. Rice Res. Inst., POB 933,
1099 Manila, Philippines), L.H. Ziska et al.,
GeoJournal, 35(3), 351-362, Mar. 1995.
Rice crop models were used to predict the effects of climate change on rice
production if CO2 levels were doubled. Different countries showed
different effects; in Southeast Asia, increased CO2 leads to
increased rice yield, while increased temperature decreased yield. Data are
still insufficient to determine the effect of increased UV-B from stratospheric
ozone depletion under field conditions. Also discusses the effect of rice
cultivation on global warming through methane emissions.
Human-Induced Climatic Change: A Summary for Environmental Managers," E.W.
Sulzman (Clim. Sys. Model. Prog., UCAR, POB 3000, Boulder CO 80307), K.A.
Poiani, T.G.F. Kittel, Environ. Mgmt., 19(2), 197-224, Mar.-Apr.
Discusses the use of GCM-based scenarios of climate change, and recommends
their use in conjunction with water resource and ecosystem models to guide
environmental management and policy, either in a no-regrets framework or as part
of a precautionary approach to natural resource protection.
Cloud and Aerosol Effects on Global Warming Using a One-Dimensional
Radiative-Convective Model," T.B. Cobb (Bowling Green State Univ., Bowling
Green OH 43403), J.A. Schumacher et al., World Resour. Rev.,
7(1), 140-154, Mar. 1995.
Educators, particularly those in the sciences, are often called upon to
explain global warming and to provide guidance for public policy development.
However, it is unreasonable to expect the average educator to have the detailed
understanding of atmospheric science and computer modeling. Educators need
understandable, PC-compatible, user-friendly computer models that are
sufficiently realistic to provide reasonable answers. This paper illustrates
uses of a simple climate model (MacKay and Khalil) that should be helpful.
Carrying Capacity and the Environment," K. Arrow (Dept. Econ., Stanford
Univ., Stanford CA 94305), B. Bolin et al., Science,
268(5210), 520-521, Apr. 28, 1995.
A report of the Second Aksö Meeting (Aug. 1994), organized by
the Roy. Swed. Acad. Sci. et al. Discusses the relation between economic growth
and environmental quality, and the link between economic activity and the
carrying capacity and resilience of the environment. Concludes that economic
liberalization and other policies that promote gross national product growth are
not substitutes for environmental policy, and may need to be accompanied by
stricter policy reforms. Economic growth is not the main issue; what matters
most is the content of growth (the composition of inputs and outputs). Economic
institutions should provide the right incentives for protecting the resilience
of ecological systems.
from Artificial Wetlands: A Global Appraisal," F. Mudge (Ctr. Social &
Econ. Res. on the Global Environment, Univ. E. Anglia, Norwich NR4 7TJ, UK),
W.N. Adger, Environ. Mgmt., 19(1), 39-55, Jan.-Feb. 1995.
Presents a revised estimate of global emissions from the production of rice
and coarse fibers that is higher than those of many previous studies which had
systematically underestimated fluxes from tropical countries. As population
increases, the demand for rice will rise. Strategies based on improved water and
fertilizer use will allow increased rice production and yields, and will reduce
Regional Goals and Policy Concerns Associated with Global Climate Change,"
Y. Yin (Atmos. Environ. Serv., 4905 Dufferin St., Downsview ON M3H 5T4, Can.),
S.J. Cohen, Global Environ. Change, 4(3), 246-260, Sep. 1994.
Uses analytic hierarchy process and goal programming to systematically build
a bridge between science and policy in a regional climate change impact study,
and applies it to Canada's Mackenzie Basin.
North-South Trade, Deforestation and Atmospheric Carbon Interactions," D.W.
Jones (Energy Div., Bldg. 4500N, MS-6205, Oak Ridge Natl. Lab., POB 2800, Oak
Ridge TN 37831), R.V. O'Neill, Resour. & Energy Econ., 15(4),
Models carbon interactions, assuming a single industrial (carbon releasing)
region producing only a manufactured good, and one agricultural region producing
a homogeneous agricultural good. Studies the effects of carbon release from
manufacturing and from agricultural land clearing on agricultural production
(through elevated CO2). Other factors influencing the carbon budget
are population changes, costs of retarding carbon releases, and the strength of
the relationship between atmospheric carbon concentration and agricultural
