Abstract
Universities are physical entities exemplifying complex human-land interaction and diverse processes. Their expansion into towns and rural areas drives urbanization, social transformations and economic development. However, with widespread human activities, surrounding ecological conditions change. The present study analyzed the implications of the changing landscape and land use/land cover around Chuka University from 2003 to 2013. Land Use and Land Cover (LULC) change was identified as a key factor driving transformations. The study used GIS and remote sensing to evaluate the dynamics of interactions which have produced the present and historical scenarios. Remote sensing provided multi-temporal data on the patterns and processes of human activities, while GIS mapped and analyzed LULC changes. Results revealed increasing growth of built-up areas, decreasing land under vegetation cover, open spaces and increase in peri-urban agriculture. Ndagani is an upcoming peri-urban center, undergoing rapid growth and expansion through physical factors, demographic changes, land subdivision and sale, accessibility and proximity to motorized roads. The rate of socio-economic transformation taking place in this area could be assessed more effectively if Public Participatory GIS (PPGIS) and biophysical factors were integrated to enhance holistic understanding and decision making for monitoring current changes and forecasting future sustainable development, information exchange and spatial interactions.
