  1. Has Population Growth Improved the Quality of Land in Africa? Analysis of the impact of increasing population density on African land profiles ECON 0428: Population Growth and Global Future Kaitllynn Saldanha Maurits Pot

  2. Major Issues • Population density • Increasing agronomic Investment • Role of technological Innovation • Flexibility of Institutions • Boserup Thesis

  3. Boserup Theory • The role of rising population density • The role of agriculture intensification • Intensification technologies that increase output allowing food production to keep pace with population growth. • Technology, innovation, and investment in human capital offset the effects of population growth. • Emphasizes the superior role of local inhabitants over foreigners. - Government investment at national and family farm levels.

  4. The Benefit of Population Growth according to the Boserup Theory: The effect of rising population densities and subsequent effects of agriculture intensification

  5. The Role of Government • Population density and intensification alone do not explain land recovery in the face of population growth. • Advantages of population growth can only be realized with government investment. -National investment  infrastructure, education, R&D -Family farm investment  saving, incentives, circulation of information.

  6. Machakos Case Study • Evidence for the Boserup hypothesis. • Study Premise: increasing population density is the source of agricultural growth in low potential dryland areas as well as high potential areas. • Illustrated the role of investment, population density, innovation and human capital improvements. • The rise of institutions to serve as management organs • The prevalence of cheaper interaction costs spurs farm innovation. • Critique to Machakos and conflicting evidence.

  7. The Role of Institutions • Divergent opinions on the role of institutions in the population-environment nexus. -Malthusian Perspective  neglects institutions -Boserup Theory  institutional change prompts technological change -Institutional adaptation related to factor endowment of a country -Inappropriate institutions leading to land degradation. • The positive role of informal institutions Informal Institutions: customs, norms and networks as the most immediate mechanism mediating the relationship between population growth and the environment. • Burkino Faso Study

  8. Conclusions • Despite a negative perception of the effect of population growth on the quality of lands, the Machakos and Burkina Faso Studies suggest that an optimistic perspective exists. • Rising population densities and intensification that population growth enables, allow for the opportunity for improved land quality. • Rather than a single trend explaining the relationship between population growth and the environment however, myriad relationships exist. • The affect of population growth on the quality of lands is dependent on investment by local governments and farmers as well as the adaptation of informal institutions. • The relationship between population growth and the environment is ultimately determined by how (and how quickly) communities adjust to population growth vis a vis external and internal factors.
