Human-Forest Interactions In Northeast Thailand, James A. Hafner Professor Emeritus Jan 1987

Human-Forest Interactions In Northeast Thailand, James A. Hafner Professor Emeritus

James A Hafner

The Northeast Thailand Upland Social Forestry (NTUSF) project was initiated in May 1985 by a grant from the Ford Foundation to the Faculty of Forestry, Kasetsart University. The project was designed as a collaborative, inter-disciplinary research program to examine social, economic, and land use changes in upper watershed areas of Northeast Thailand. It was also conceived of as an effort to promote interdisciplinary collaboration and a systems approach to the way these complex issues are conceived, examined and analyzed.  A medium term goal was to use the knowledge gained from case study research to inform planning for a pilot program …

Implications Of Atmospheric Test Fallout Data For Nuclear Winter, George H. Baker Jan 1987

Implications Of Atmospheric Test Fallout Data For Nuclear Winter, George H. Baker

George H Baker

Atmospheric test fallout data have been used to determine admissible dust particle size distributions for nuclear winter and nuclear fallout studies. The research was originally motivated by extreme differences noted in the magnitude and longevity of dust effects predicted by particle size distributions routinely used in fallout predictions versus those used for nuclear winter studies. Three different sets of historical data have been analyzed:

1. Stratospheric burden of Strontium-90 and Tungsten-185, 1954-1967 (97 contributing events) 2. Continental U.S Strontium-90 fallout through 1958 (75 contributing events) 3. Local Fallout from selected Nevada tests (16 events)

The contribution of dust to possible …
