Part 2: Issues in Sustainable Development

Population                                       

SummaryPopulation

 
If birth rates are far higher than death rates, population growth is too rapid to be sustainable. Changing population growth rates requires examination of the factors that influence or constrain choices about family size. Human well-being and the environment, both in cities and in rural areas, are negatively impacted by rapid population growth.

Assignment Questions

  1. Population: What are the most significant demographic trends occurring in the African region today?
  2. Interconnections: Population & Ecosystems: Explain some of the connections between rapid population growth and environmental degradation.
  3. Interconnections: Population & Human Needs: Fertility, the number of children a woman gives birth to, is one of the central variables in studying demographic changes. Before the advent of modern medicine, populations were relatively stable throughout the world, with high mortality balanced by high fertility. As better health care and sanitation becomes available, infant and child mortality drops, and population growth accelerates. In most developed countries, a subsequent drop in fertility is observed, as women marry later and couples choose to have fewer children. This process is referred to as the demographic transition, and it implies a strong relationship between increasing levels of human development and decreasing average fertility. Explain some of the connections between fertility and poverty, education, and health.
