What are the effects of population growth on land use change? Despite the interest in and importance of this question, there is a relatively small body of carefully designed research that begins to provide answers to it. In order to make progress in this field we need to understand why careful research on this topic is so scarce, examine the work that has been done, and propose ways to encourage research in an area that may be critical to the future of many countries.

Classical economists, beginning with Malthus, stressed the difficulty of maintaining a steady or increasing standard of living given a finite resource base and a growing population. Malthus argued that food production could only grow at a linear rate while populations grew geometrically; thus population growth would ultimately outstrip the ability of the economy to meet the demand for food (Malthus, 1798). Although agricultural production has so far met and often exceeded populations' growing needs for food, there remains a concern among many natural scientists that the ecological limits

Scholarship | Negative Population Growth

Research on population growth and land use change has been made more complicated by the use of two conflicting paradigms, one based in natural science (or classical economics) and the other in neoclassical economics. The natural science paradigm places more emphasis on the finiteness of resources than on technological and institutional change and the accumulation of physical and human capital. This paradigm views population growth as a threat to the inherent limits of arable land to provide food, shelter, and sustenance. The neoclassical economics paradigm emphasizes the accumulation of both physical and human capital and the substitution of abundant factors for scarce ones. This paradigm suggests that population growth can be the impetus for technological and other changes that mitigate or even eliminate the effects of natural resource limits on economic well-being. Empirical research is capable of indicating which of these paradigms has more explanatory power, but the research base is thin and has not yet led to a body of knowledge on which public or scientific consensus has developed.

Today's population dynamics are unique. Although there is a negative correlation between density and natural increase (births minus deaths; see ), many countries that are already very densely populated are still experiencing high rates of population growth (see Figures and ). Most of the research on population and land use change has focused on levels of population and population densities. However, rates of change in high-density countries may also be critical variables.

Neoclassical economists are also concerned with whether an economy can provide an increasing or steady standard of living given a finite resource base and a growing population. To determine whether output growth can keep up with population growth, attention is focused on two factors: technological advance and the substitution of scarce factors with more abundant ones (Stiglitz, 1979; Simon, 1981). Under well-functioning markets, as land resources become scarce, incentives will increase for people to develop technologies to farm previously unused land (extensification) and to increase production per existing unit of land (intensification). People will also substitute more abundant resources, such as fertilizer and labor, for land. In her widely cited work, Ester Boserup (1965, 1970, 1981) documented how, in response to greater population density, farmers reduced their fallow periods, began to use the plow, and implemented multiple cropping cycles to make their land more productive. Although she acknowledged that land degradation could occur as hills were cultivated or fallow periods excessively shortened, Boserup concluded that technology, such as terracing and fertilizer, could minimize the damage.
