Item #d89oct37

An Exploration and Assessment of the Implications of Climatic Change for the Boreal Forest and Forestry Economics of the Prairie Provinces and Northwest Territories: Phase One (SRC Pub. No. E-906-61-A-88), E.E. Wheaton, T. Singh et al., 1988. For sale from Environ. Div., Saskatchewan Res. Council, 15 Innovation Blvd., Saskatoon, Saskatchewan S7N 2X8, Can.

Goals of this continuing study, one of the series commissioned by the Canadian Climate Centre, are to assess relevant current knowledge, develop a framework to assess the use of computer models for studying climate change and its impacts, and make preliminary impact assessments. An extensive literature review was undertaken concerning impacts on tree growth and physiology, direct effects of CO₂ enrichment, productivity, economics, forest zonation, forest fires, and insects and diseases. For several climate change scenarios predicted by general circulation models, the potential northward shift of the northern boreal forest boundary is 100 to 700 km. Biomass productivity increases of up to about 50% are possible in the north. A climatic zonation model developed predicted shifts of the aspen parkland and boreal temperate ecoclimatic zones. Development of a dynamic economic model was started, some preliminary estimates made, and needs for further work identified.

PAN-EARTH Project--Annual Report 1988-89, 102 pp., 1989. Available from Global Environmental Program, 468 Hollister Hall, Cornell Univ., Ithaca NY 14853 (607-255-4676).

PAN-EARTH (Predictive Assessment Network for Ecological and Agricultural Responses to Human Activities) is carrying out case studies on effects of nuclear war and global climate change on a wide variety of biological, agricultural and social systems, continuing the national case studies established by the International Council of Scientific Unions. This report gives progress on studies in the People's Republic of China, Venezuela and sub-Saharan Africa, which involve research by local scientists. Plans for continued funding, research and related activities are also given.

Item #d89oct39

Stratospheric Ozone Depletion and Agriculture, 12 pp., Feb. 1989. Available (no charge) from Inst. Food & Agric. Sci., Univ. Florida, Gainesville FL 32611 (904-382-6888).

Documents the results of a workshop organized in cooperation with the U.S. Department of Agriculture, to assess the current state of knowledge on the effects of increased UV-B radiation on the biosphere, and research needs for understanding effects on crop productivity. Research recommendations are made for four major areas: basic studies, instrumentation, monitoring, and interdisciplinary basic and applied research to support modeling of potential changes in agriculture and natural ecosystems.

Item #d89oct40

Rise in Sea Level and Coastal Zone Planning, 19 pp., Oct. 1987. Prepared by Shevenell Gallen & Assoc. for Office of State Planning, 2.5 Beacon St., Concord NH 03301 (no charge).

Describes expected shoreline changes in the State of New Hampshire from climate-induced sea level rise, and outlines an approach for evaluating in detail impacts on humans and natural resources.

Item #d89oct41

Triticale--A Promising Addition to the World's Cereal Grains, 105 pp., 1989. Advisory Committee on Technology Innovation, National Research Council. Order from Bd. on Sci. & Technol. for Intl. Devel., NRC, 2101 Constitution Ave. NW, Washington DC 20418 (202-334-2684); $12.

Triticale is a hybrid of wheat and rye with characteristics that may make it suitable for certain parts of the world where climate is altered by global warming--drought tolerance, good pest and disease resistance, and adaptibility to poor soils. This report covers history, limitations and uncertainties, breeding, food and animal feed uses, international experience with the crop, and research needs.
