In October of 1992, the Harvard Center for Population and Development Studies sponsored the Roger Revelle Memorial Symposium on Population and Environment. Two dozen eminent scientists—all friends, colleagues, or students of Roger Revelle—presented papers in a broad range of disciplines that reflect the remarkable scope of Revelle’s professional and academic contributions during his lifetime. This volume is a selection of the symposium papers.

A memoir of Revelle’s exposure to poverty in Pakistan, igniting his interest in the contribution that science could make to improving the lives of people in developing countries, serves as a moving introduction to the volume. This book stands as an enduring memorial to Roger Revelle’s lifelong concern that scientific developments contribute to comfortable, civilized survival in all countries of this increasingly crowded world.

    Today Ireland’s population is rising, immigration outpaces emigration, most families have two or at most three children, and full-time farmers are in steady decline. But the opposite was true for more than a century, from the great famine of the 1840s until the 1960s. Between 1922 and 1966—most of the first fifty years after independence—the population of Ireland was falling, in the 1950s as rapidly as in the 1880s. Mary Daly’s The Slow Failure examines not just the reasons for the decline, but the responses to it by politicians, academics, journalists, churchmen, and others who publicly agonized over their nation’s “slow failure.” Eager to reverse population decline but fearful that economic development would undermine Irish national identity, they fashioned statistical evidence to support ultimately fruitless policies to encourage large, rural farm families. Focusing on both Irish government and society, Daly places Ireland’s population history in the mainstream history of independent Ireland.
    Daly’s research reveals how pastoral visions of an ideal Ireland made it virtually impossible to reverse the fall in population. Promoting large families, for example, contributed to late marriages, actually slowing population growth further. The crucial issue of emigration failed to attract serious government attention except during World War II; successive Irish governments refused to provide welfare services for emigrants, leaving that role to the Catholic Church. Daly takes these and other elements of an often-sad story, weaving them into essential reading for understanding modern Irish history

It is everywhere recognized that China's mid-century population is a world problem, and not merely a national one. In spite of numerous studies on China's population by occidental and Chinese scholars, many aspects of the subject remain obscure because of the problems of interpretation. Ping-ti Ho makes a thorough examination of the machineries with which population data were collected in different periods. This has led him to redefine, among other things, the key term ting, which has served as almost the sole basis of reconstruction of China's historical population by many well-known authorities.

The second part of the book deals with factors which have affected the growth of China's population during the last six centuries: the approximate extents of cultivated conditions, institutional factors like fiscal burden and land tenure, and major deterrents to population growth such as floods, famines, and female infanticide. In his conclusion Ho correlates population data with economic and institutional factors of various periods and he suggests ways for a reconstruction of China's population history. While it is primarily an historical study, the book also correlates the past with the present.
