| dc.description.abstract | Sustainable land management is a knowledge based mechanism through which land is managed
to ensure that land as a resource is optimally utilized taking into consideration the current users
and users while ensuring that the future generations are taken into consideration. In this research,
the focus was on sustainable land management in the informal to help us understand the practices
of managing land developments, the changes in land use land cover and how sustainable they
are. The use of Geospatial Information Science and Remote Sensing has been used to help in
monitoring and evaluating the land use land cover change as well as assess the sustainability of
these changes with respect to the factors that have contributed to these changes. The study area
for this research was Manyatta B, an informal settlement with Kisumu County Kenya. Landsat
satellite imageries of three different time periods, 2000, 2010 and 2020 were acquired by United
States Geological Survey (USGS) earth explorer site and quantify the changes in the study area
from 2000 to 2020 over a period of 20 years. Supervised classification methodology was
employed using maximum likelihood technique in ArcGIS Desktop 10.2.2 Software. The images
of the study area were categorized into four different classes namely vegetation, trees, bare land,
and built-up areas. The results indicate that during the last two decades, built-up land had been
increasing by 0.85% annually over the years; there was no relative average change in tree cover
while bare land and vegetation have decreased by 0.65% and 0.3% respectively. Data from the
questionnaires showed that these changes have been influenced by different factors like a various
in the weather patterns, localization of development through the County government and
population increase. | en_US |
