![]() ![]() ![]() The practice of slash-and-burn agriculture (known locally as “shifting cultivation”) and cutting trees for making charcoal and firewood has also contributed to the deforestation of Kigoma. This high population growth has led to a significant reduction in the amount of forested land around Gombe National Park, as people clear the land to make way for houses and farms. A large immigrant population-mainly refugees from Burundi and Democratic Republic of Congo-has combined with Kigoma Region’s very high fertility rate to produce a regional population growth rate of 4.8 percent per year-the highest regional growth rate in Tanzania, which has an overall growth rate of 2.4 percent. Kigoma Region, which is just over 37,000 square kilometers in size, has a human population of 1.7 million. It is now largely in the hands of humans-park staff, researchers, rural development professionals, tourists, and local communities-to conserve Kigoma’s remaining forests and to create and maintain a healthy environment so that the chimpanzees of Gombe might survive the 21st century.Population Growth and Human Activity Put Pressure on the Park Either habitat loss or regularly occurring disease outbreaks can precipitate a significant population decline for any particular species-but when both come into play, the results can be especially devastating. The reasons for the drastic decline in Gombe’s resident chimp population are well-known to scientists and park personnel: too little habitat and too much disease. But over the past four decades, the chimpanzee population of Gombe has dropped from about 150 at the time Goodall arrived to approximately 90 today, while human population growth in the region and specifically around the park has soared. Gombe National Park, a 35-square kilometer park in Kigoma Region in northwestern Tanzania, is most popularly known as the place where Jane Goodall conducted her pioneering research on chimpanzees beginning in the 1960s (see map).
