Presented are summaries of various activities within a seminar organized by Unesco at Cali, Colombie, to examine scientific aspects of the mangrove ecosystem and the human impact upon it. Specifically, the aims of the seminar were: (1) to review studies on mangroves being carried out in Latin America and the Caribbean; (2) to foster contacts…

This document reviews the process by which the cost benefits of using LANDSAT on an operational basis in the surveillance of lake eutrophication was established. The program identified the information needs of users conducting on-going water quality programs, transformed these needs into remote sensing requirements, produced LANDSAT maps and data…

Demand projections indicate that Oahu's natural ground water supply will be fully developed by the year 2000. Supplementary water resources will need to be developed in keeping with the growth of the economy and population. The author, chairman of the Honolulu Board of Water Supply, authoritatively discusses types of ground water in Hawaii, and…

The goals of the Caltech Population Program are to increase understanding of the interrelationships between population growth and socioeconomic and cultural patterns throughout the world and to communicate this understanding. This series of occasional papers is one step in the process of communicating research results. The papers deal primarily…

This key to freshwater and anadromous fishes of California is included as the fifth of a series of guides being produced by Project MER (Marine Ecology Research). This project is part of the effort to improve environmental education in the San Francisco Bay Area schools by gathering and organizing data on the ecological character of the San…

The need for a Gestalt Theory of neighborhood development was described in this paper. A model based on scale was developed in which small scale represents an isolated Appalachian who depends upon neighbors and kin and large scale represents a person who has developed a large number of relationships so that he is less dependent upon any one of…

The origins and nature of air pollution, from earliest days to the present, are examined in this book. Although air pollution has been with us since the discovery of fire, it is proffered that the major culprit now is the burning of gasoline and low-grade heating oil. All other sources of air pollution are negligible. The main thesis is that only…

This article examines the relationships among solid waste disposal, air pollution, and human disease. It is estimated that solid waste disposal contributes 9.7 percent of the total air pollution and 9.9 percent of the total air pollution health effect. Certain disposal-resource recovery systems can be implemented to meet air quality standards. (MR)
