enabling the monitoring of land use changes over time with high temporal resolution (Coppin
et al., 2004). GIS facilitates the analysis and visualization of these changes, integrating various
data sources to create detailed land use maps (Longley et al., 2005).
Coastal areas, like Cox's Bazar, are particularly dynamic and susceptible to land use changes
due to both natural and anthropogenic factors. Studies in similar coastal regions have
demonstrated the significant impacts of tourism, urban development, and agricultural practices
on land use patterns (Maiti & Agrawal, 2005). These studies underscore the importance of
sustainable land use planning to mitigate environmental degradation and enhance resilience to
natural disasters.
Tourism is a major driver of land use change in many regions, including Cox's Bazar. Research
has shown that tourism development often leads to the conversion of natural landscapes into
built environments, affecting local ecosystems and communities (Gössling, 2002). In Cox's
Bazar, the rapid growth of tourism has led to significant land use changes, with implications
for environmental sustainability and socio-economic development (Sarker et al., 2019).
Agricultural practices are another major factor influencing land use patterns. In Bangladesh,
shifts in crop types, farming practices, and land management strategies have led to changes in
land use, impacting soil health, water resources, and biodiversity (Rahman et al., 2010). The
transition from traditional to intensive agricultural practices has been particularly significant in
driving land use changes in regions like Ramu Upazila.
Urbanization is a critical factor in land use change, particularly in developing countries. The
expansion of urban areas often leads to the conversion of agricultural and natural lands into
residential, commercial, and industrial zones (Seto et al., 2011). In Cox's Bazar, urban
expansion has been accelerated by population growth and economic development, resulting in
significant changes in land use patterns (Islam et al., 2014).
Natural disasters, such as cyclones and floods, play a significant role in shaping land use
patterns in coastal regions. Studies have shown that these events can lead to both temporary
and permanent changes in land use, as communities adapt to the impacts of disasters (Adger et
al., 2005). In Cox's Bazar, the frequency and intensity of natural disasters necessitate a focus
on resilient land use planning to reduce vulnerability and enhance recovery (Haque & Nicholls,
2018).
The literature highlights various methodological approaches for detecting and analyzing land
use changes. These include multi-temporal satellite imagery analysis, land use/land cover
(LULC) classification, and change detection algorithms (Lu et al., 2004). Each approach offers
different strengths and limitations, with the choice of method depending on the specific
