Multiple-Scale Integrated Assessments of Societal Metabolism: Integrating Biophysical and Economic Representations Across Scales

The crucial challenge for integrated analyses of socioeconomic systems is keeping coherence in their multidimensional representation. Our approach describes the hierarchical structure of socioeconomic systems using the profile of allocation of human activity over a set of compartments defined at different hierarchical levels (e.g., whole countries, economic sectors, individual households). Compartments are characterized in terms of intensive variables (intensity of both exosomatic energy flows and added value flows per unit of human activity) and the extensive variable Total Human Activity population. In this way, relations of congruence across hierarchical levels can be used to link non-equivalent analyses. That is, changes in demographic variables, economic variables, technical coefficients, indices of environmental loading, institutional settings, and social aspirations are no longer independent of each-other even if described within different scientific disciplines.     

Three Centuries of Global Population Growth: A Spatial Referenced Population (Density) Database for 1700–2000

The Earths surface has changed considerably over the past centuries. Since the start of the Industrial Revolution in the early 1700s, humans from the Old World started to colonize the New World. The colonization processes lead to major changes in global land use and land cover. Large parts of the original land cover have been altered (e.g., deforestation), leading to extra emissions of GHGs to the atmosphere and enhancing global climate change. The spatial and temporal aspects are still not very well known. More and more global integrated environmental assessments concerning global sustainability require long time series of global change indicators, of which population is an important one. This study presents an update of the geo-referenced historical population maps for the period 1700–2000, part of the History Database of the Global Environment (HYDE), which can be used in integrated models of global change and/or global sustainability.     

Population growth and road construction: Looking to traditional indigenous ways

Population growth is linked to road building which is in turn unfortunately linked to what is commonly called sustainable development. The biggest implication of late is that the United Nations' International Conference on Population and Development—as it focused so heavily on feminist agendas, education and economic advancement—did not address a major cause of population growth.Overpopulation in some northern nations, notably the United States, is overlooked due to official neglect of the scientific measurement of carrying capacity, and due to political considerations in discussing immigration even as an environmental issue or component of overpopulation.Traditional indigenous peoples' population sizes and such societies' ethic toward their land are indicated as models of sustainability.     

The welfare effects of labour force growth with internationally mobile capital

The effects of labour supply growth on the welfare of preexisting destination and non-emigrating source populations are analysed. This growth occurs in open economies where free trade in capital goods is possible. Traditional small economy arguments for population growth rely on the existence of priced though internationally immobile factors. When all factors are freely-traded and population grows naturally the case rests either on market distortions or common property within families. In an integrated world labour growth can lead to capital flight and increasing wage differentials. With international interactions, immigration increases preexisting welfare in destination countries but generally (not always) reduces it for non-emigrants in source countries. Immigration provides efficiency gains to all originally resident in source countries. Natural population growth anywhere promotes efficiency gains everywhere.     

Population in context: A typology of environmental driving forces

This paper presents a typology and qualitative model of causation for use in assessing the relative contributions of population growth to problems of pollution, lost biodiversity, and natural resource depletion. Population growth is placed in context as one of eight key driving forces that shape environmental quality today. It is treated primarily as an impact amplifier, along with technology. Root causes are traced to paradigmatic beliefs—especially anthropocentrism and contempocentrism—which find expression in unsustainable consumption patterns and designs of political economy.     

Transmigration in Indonesia: An evaluation of a population redistribution policy

In this article an attempt is made to evaluate Indonesia's population redistribution policy—transmigration—from 1969 onwards. In addition to population redistribution, transmigration also has socio-economic and political objectives. In spite of the fact that in monetary terms transmigration has become one of Indonesia's main development programmes and the budget per transmigration family has increased enormously since 1969, it is established that for several years the ambitious targets could not be realized. In addition, studies show that in several cases the many promises of the transmigration authorities could not be met. With respect to the objective of population redistribution, it is concluded that so far transmigration has hardly influenced Indonesia's population distribution; only in specific receiving areas have the effects of transmigration been significant. Furthermore, it is shown that there is reason to doubt the role which the agriculturally-oriented transmigration programmes can play in the regional development process. In addition, there is evidence that in some cases the schemes have also been used as an instrument to serve (implicit) political aims.This is a revised version of NIDI Working Paper No. 43, An Evaluation of Recent Indonesian Transmigration Programmes, November 1983.The author would like to thank Dr. Ir. Frans Willekens for his valuable advice and stimulating comments. Thanks are also due to Lieneke Hoeksma for editing.     

On Exponential Growth and Half-Lives: A Comment on Bermingham

A recent paper (hereafter referred to as the Paper), Bermingham (2003), presented what appeared to be an analytical review of current situation of declining population growth rates in many parts of the world. The Paper suggested that the increasing growth rates before about 1970 constituted exponential growth, but that the currently declining growth rates were not exponential growth. Hence, the paper asserted that we should not use the terms exponential growth and doubling times in describing the current situation. Many of the suggestions in the paper are contrary to established mathematics. These suggestions are examined here in some detail.     

Revisiting carrying capacity: Area-based indicators of sustainability

Conventional wisdom suggests that because of technology and trade, human carrying capacity is infinitely expandable and therefore virtually irrelevant to demography and development planning. By contrast, this article argues that ecological carrying capacity remains the fundamental basis for demographic accounting. A fundamental question for ecological economics is whether remaining stocks of natural capital are adequate to sustain the anticipated load of the human economy into the next century. Since mainstream (neoclassical) models are blind to ecological structure and function, they cannot even properly address this question. The present article therefore assesses the capital stocks, physical flows, and corresponding ecosystems areas required to support the economy using ecological footprint analysis. This approach shows that most so-called advanced countries are running massive unaccounted ecological deficits with the rest of the planet. Since not all countries can be net importers of carrying capacity, the material standards of the wealthy cannot be extended sustainably to even the present world population using prevailing technology. In this light, sustainability may well depend on such measures as greater emphasis on equity in international relationships, significant adjustments to prevailing terms of trade, increasing regional self-reliance, and policies to stimulate a massive increase in the material and energy efficiency of economic activity.     

Societal Metabolism and Multiple-Scale Integrated Assessment: Empirical Validation and Examples of Application

This paper presents empirical data to validate two points. (1) An integrated analysis of societal metabolism bridges an economic view of changes in socioeconomic systems with a biophysical representation of them. To obtain this check, it compares a biophysical indicator of development BEP with 24 traditional indicators of material economic development. The comparison covers a sample of 107 countries of the world, comprising more than 90% of the total world population (year 1993). (2) The concept of societal metabolism is useful to make biophysical analysts aware of constraints implied by economic viability and to make economic analysts aware of constraints implied by biophysical viability. To prove this point three practical examples of misunderstanding in the field of sustainability analysis are discussed.     

From stagnation to growth: Revisiting three historical regimes

This paper explores the role of mortality in the long transition from Malthusian stagnation to sustained economic growth. An endogenous child mortality rate that varies inversely with parents standard of living is added to the framework in Galor and Weil (AER 2000). In our version of the model, the transition from stagnation to growth, triggered by an exogenous shock to technology, comprises a mortality revolution succeeded by a demographic transition.This paper has benefitted from discussions with and suggestions made by KarlGunnar Persson, Christian Schultz, and, particularly, Christian Groth at the University of Copenhagen. I gratefully acknowledge the insightful criticisms of two anonymous referees, and I thank Paula Madsen for English proof-reading. Responsible editor: Alessandro Cigno.     

Earth,the Business of the Future: From Ego Energy to Eco Energy

Just as we have a turn around manager to save a failing business organization, so it is held, we need a turn around perspective to retrieve the Earth from being in a deficit position. Hence the paradoxical emphasis upon the Earth as the business of the future. Two important distinctions are offered which together provide a new frame of reference for bonding the human and the Earth. The initiating event for the first distinction was a business conference whose purpose was to explore the emerging domain of ego energy. In a parallel way, it is proposed we explore the yet to be discovered domain of eco energy. With eco energy we open our narrowed human window to cosmic perception. With cosmic perception, the energy of the universe can flow through us. The second distinction is between looking at and seeing. Looking at refers to treating our world as a collection of objects. As a collection of objects the Earth can be processed as a series of business transactions. With seeing we relate to our world as a communion of subjects. Such seeing offers transforming power for the human and the Earth to engage in the dialogue of powerful listening and speaking on both individual and planetary scale. These two sets of distinctions are sounded like echo chambers against ten ecologically guiding statements. These ten guiding statements become a reality-testing, experiential framework. Such a turn around perspective offers a different vision to be operationalized in our individual, community, and business lives. Then we can see clearly and respond with eco energy to the Earth, the business of the future!     

The evolutionary basis of sex variations in the use of natural resources: Human examples

People, unlike other primates, regularly consume foods acquired by others. When people forage for a living, women and men customarily acquire different foods and consume the products of each other's work. This distinctively human sexual division of labor has seemed the hallmark of human resource use. If men and women have different economic specialties, marriage creates a social unit that deploys their different capacities to serve family needs. Other distinctively human patterns then seem to arise from this fundamental economic cooperation between the sexes. In recent decades, the use of evolutionary theory to investigate and explain social behavior across the living world has revealed pervasive conflicts of interest between (as well as within) the sexes. Application of these tools to human examples shows the sexual division of labor to be the economic aspect of different and conflicting reproductive agendas for women and men. A review of some examples from communities where people hunt and gather for a living illustrates that families are not units of common economic interest. As with other primates, males and females have different reproductive goals and these differences shape sex differences in patterns of resource use.     

Demographic Efficiency: Concept and Estimation

The concept of demographic efficiency is proposed and data envelopment analysis (DEA) is introduced as a method for determining which countries are demographically efficient. While the purpose of the paper is primarily to introduce the concept and the method, several simple examples are used for purposes of illustration. The first two explore how efficiently countries have converted their level of development (the input) into male and female life expectancy at birth (the outputs). The second two reverse the postulated relationship, treating life expectancies as inputs reflecting general health status of a population, and level of development as the output. Countries are said to be efficient if they have achieved the maximum output observable for a given level of input, or if they have minimized the inputs needed to achieve a prescribed level of output. Together, the efficient cases form an efficiency frontier. DEA, a form of linear programming, also permits the degree of inefficiency of countries lying behind this frontier to be measured by calculating the extent of the output slacks that are present. Output slacks are the shortfalls in the level of performance that could have been achieved given the inputs available, and may themselves be treated as independent variables in explorations of the sources of demographic inefficiency. One example of such an exploration is offered—an attempt to account for shortfalls in female life expectancy, given levels of development.     

Cross-National Variation in the Size of Passenger Car Fleets: A Study in Environmentally Significant Consumption

To help build theory on the factors contributing to environmentally significant consumption, I analyze cross-national variation in the size of passenger car fleets. I take into consideration multiple factors—demographic, economic, and socio-political—that potentially influence motorization. The results indicate that all types of factors have a significant influence on national motorization, although economic factors are the most influential. I conclude that in order to properly understand consumption practices we need to consider multiple perspectives and recognize that there are global structural conditions that form the context in which causal processes unfold.     

Environmental Migration and Sustainable Development in the Upper Reaches of the Yangtze River

This paper explores the demographic impacts of the implementation of the Grand Development in West China policies and environmental rehabilitation projects in the upper reaches of the Yangtze River. It analyses the interaction between the environmental reconstruction and environment-related migration in this region. The intertwined nature of environmental, ethnic, and poverty problems not only bears negatively upon the alleviation of poverty conducing to the accruement of wealth of the poverty-stricken population, but also hinders the rehabilitation of the environment. It brings forth some opinions regarding improving the capacity of regional sustainable development through environmental migration.     

Exponential Population Growth and Doubling Times: Are They Dead or Merely Quiescent?

Exponential Growth and Doubling Times: Use of these popular population buzzwords of the last half of the twentieth century was fully justified by the growth rates of that period. However, those growth rates have now all but disappeared and so have the underlying reasons that those buzzwords made sense. Misuse of such expressions today costs credibility. Though the world's population growth certainly does remain vigorous and robust, creating many reasons for concern, nowhere today is growth projected as exponential. The essence of exponential growth is analyzed and distinguished from exponential curves, and non-exponential growth. Several types of current population growth are recognized, none being exponential. In periods of non-exponential growth, a Doubling Time calculated from a single annual growth rate is grossly erroneous and often absurd. Other standard measures of growth are needed. United Nations projections should include figures for percentage growth by 2025 and 2050.     

Population growth,environmental awareness,and policy direction

Many policy analysts, commentators, and researchers claim that the issue of human population growth no longer receives the attention and concern it once enjoyed in both the popular and specialized media. Other commentators state that scientists and decision-makers are held captive by media-savvy environmentalists who seek to fulfill a political agenda by limiting population expansion. I investigated the change in media coverage of population issues by tallying the number of population-related articles listed during 1967–1989 in 3 periodical index services. Media coverage has declined sharply since the early 1970's. Possible causes of the decline are discussed in the context of the larger debate between population pessimists and population optimists.     

The population explosion: Where is it leading?

Over the past few centuries world demography has been characterized by both continuous absolute growth and a steadily increasing rate of growth. From 1650 or earlier to at least 1957 it was always possible to say that never has world population been so large and never has the time necessary for it to double been so short. While there are now some signs to suggest that population doubling times are stabilizing, or even increasing, the population increase in absolute numbers is nevertheless greater each year, and the rate of growth may still be faster than a simple exponential function. There can be little doubt that too large a population, together with the pressures stemming from its demands for an even higher standard of living, sets requirements greater than our planet can safely sustain. This article reviews some aspects of global population data and population dynamics.     

Utilitarian tradeoff between population growth and income growth

Utilitarian social welfare functions were devised for a world with a fixed population. With endogenous population, Edgeworth conjectured that the Benthamite principle of maximizing total utility (classical utilitarianism) would lead to a larger population size and a lower standard of living than the Millian principle of maximizing per capita utility (average utilitarianism). One objection to the Benthamite criterion was that its application to a world with finite resources often implied large population size in conjunction with an embarrassingly low average standard of living. In a static environment with altruistic parents, this may not be warranted. In a growth situation, this criticism is even less likely to be supported. This paper extends the comparison of classical and average utilitarianism from a static to a dynamic and endogenously growing economy. Using a stylised endogenous growth framework, it confirms that the Benthamite population growth rate exceeds the Millian growth rate. In terms of the rate of growth of per capita income, the reverse is true. Having the standard of living often increasing under the Benthamite criterion, our results thereby depart significantly from the repugnant conclusion levelled against classical utilitarianism.We would like to thank an anonymous referee for helpful suggestions.
