In partnership with the Jane Goodall Institute (JGI), NASA scientists have provided assistance in monitoring, forecasting and in the conservation of habitats across chimpanzee range in Africa. Between 1972 and 1999, significant deforestation had occurred in the region outside the boundary of the Gombe National Park, Tanzania to the detriment of the park's chimpanzee population as well as to the that of the local communities living in the region.

In 2005, JGI initiated a forest monitoring program, training, and in 2009 equipping, community members with GPS-enabled Android smart phones or tablets to report their observations on forests threats and wildlife. Combining NASA remote sensing data with citizen science observations assisted the local communities and district governments in developing and implementing land use plans, leading to improved decision making and facilitating the establishment of village land and district forest reserves.

This visualization shows the reforestation that occurred due to this effort in the Kigoma Region of Tanzania, just south of the Gombe National Park between 2005 and 2014. From a global view, we zoom to the village of Kigalye, Tanzania on the coast of Lake Tanganyika. The two visualizations shown here follow the identical view but reflect the state of the region in these two different years. Satellite images from each year are shown blanketing the topography of this region allowing us to compare the forest cover change. We stop at the village of Kigalye in order to view the location where a landslide had done significant damage prior to 2005 and slowly move northward up the valley over Kizuka stream to the southern border of the Gombe National Park.

With the information provided by the forest monitoring program, local communities that are better equipt for planning and managing their natural resources have made a positive impact on forest regeneration in the region.


This image shows the location of the Gombe National Park, show in a solid green color, along Tanzania's coast bordering Lake Tanganika.  Below the park we see the rectangular region draped with the satellite data. The village of Kigalye is shown in the lower left-hand corner of this rectangular region.
