Detecting forest degradation in Marakwet district, Kenya, using remote sensing and GIS : in cooperation with SCC-Vi Agroforestry : a minor field study
Author
Summary, in English
Deforestation is a widespread problem and has many negative impacts. The biggest threat
to forest is human activities. Despite increasing efforts regarding forest management and
forest conservation, the deforestation continues at a high rate to give space for other land
uses such as agriculture and pasture. The world’s population continues to grow and
Africa is the continent with fastest growing population. During the last 100 years this has
led to major changes in the African landscape, and Kenya is no exception.
This MFS (Minor Field Study) was conducted in cooperation with the nongovernmental
organization SCC-Vi Agroforestry. The study area is located in Marakwet district in
western Kenya and the district has one of the largest remaining natural forests in the
country. At the same time, the area is experiencing ongoing illegal deforestation.
The aim of the study was to investigate and map the deforestation in the study area during
the 23 years period from 1986 to 2009 by using satellite data. Furthermore, the aim was
to create a future scenario. Data of the population in the district was then compared with
the results to find a correlation.
The result indicates great changes in forest cover. During the 23 years period, 4 149
hectares of forest have been cleared in the study area, representing a decrease of 14
percent. The deforestation rate has decreased but the problem remains. If nothing is done
to prevent the ongoing deforestation, 45 percent of the forest in the study area will
disappear until the year 2100.
