Case study: Population distribution in Brazil p105
Why is the Amazon rainforest sparsely populated?
In the interior of Brazil, population densities are low because of extremes of physical factors
such as infertile soil and a humid climate.
Equatorial climate is hot (28°C) and wet (over 2000mm) all year with high humidity
Density of the jungle vegetation makes it difficult to penetrate and to clear, and
communications are poor
Soils are infertile and easily leached and eroded once the trees are removed
Diseases spread quickly (yellow fever)
Traditional type of farming is shifting agriculture, which can only support low
Why has there been an increase of population in the Amazon basin?
In recent years, the opening up of the Amazon Basin has seen an increase in population
density with people working in the mines, plantations and cattle ranches.
Why is the south east coast of Brazil densely populated?
High population densities are due to:
Fertile agriculture land use for vegetables, fruit and cattle as well as large coffee
Large towns and cities such as Rio de Janeiro with its commercial and industrial
Excellent communication links and a wide variety of employment and services
High concentrations of people ion the cities, and high birth rates
