This study focused on “Inventorying Landscape Elements and Patterns of the Maheshkhali Island, Cox’s Bazar”. It mainly emphasizes on the present Landscape elements and state of Landscape pattern of the Maheshkhali Island. It is an offshore island of the Bay of Bengal. Due to its geo-physical location, strong wave actions and wind flow are prevailing in the western side. On the other hand, in the eastern side, wave actions and wind flow are comparatively less strong. So a complex landscape pattern has been developed in the island. The data are collected from primary sources. Questionnaire survey, field observation, informal interview, Group discussion etc. methods and techniques are employed for data collection. The topo-sequences of the landscape were identified. Then the resources available and their state of utilization along the topo-sequences have been documented. Next attempt has been taken to identify and document the stresses developed due to the Land transformation among and within the broader landform units. Finally the research highlighted on the possible ways to mitigate the stresses on the landscape.

The world largest mangrove forest Sunderbans is located the southern coastal zone of Bangladesh and India. The ecologically rich world heritage site (UNESCO-1997) Sundarbans have been playing important role to protect the natural disaster. The economic importance of mangrove ecosystem is remarkable for Bangladesh and India both country. The mangrove bio-diversity and ecosystem of Sundarbans have created world famous tourist spot. During the demographic growth the Sundarbans have been decreasing. This research focused on geo-spatial charge of this mangrove forest during last 244 years. Historical maps Geo-informatics tools and techniques specifically Remote Sensing (RS), Geographical Information System (GIS) have been used to explore these changes. About 56.48% of total Mangrove forest have been lost during last two and half century with 0.23% yearly trend. The last half century it have lost 0.62% per year. The decreasing rate of Indian part more than Bangladeshi part. That is dangerous massage for Natural disaster protect, economy, Mangrove ecosystem and bio-diversity.

The southern part of Bangladesh is bounded by the Bay of Bengal. Three major river systems such as; Brahmaputra-Jamuna, Ganges-Padma and Surma-Kusiara have been developed the Ganges-Brahmaputra-Meghna (GBM) floodplain, this are 80% area of Bangladesh. These rivers carry huge sediments from upper Himalayan region during at monsoon period. On the contrary, as the costal part of Bangladesh is open to the sea, so high wave actions, strong wind flow, tidal actions are prevailing here. Consequently, coastline of this part is unstable and dynamic. Coastline change dynamics is significant for disaster management, coastal planning and environmental management. For the delineation of coastline identification, Rennell’s map (1776), Landsat MSS (1976) and Landsat OLI (2016) images have been interpreted using the tools of Remote Sensing Technology and Geographic Information System (GIS) of Geo-informatics. During 240 years from 1776 to 2016 about 3892 km² landform have been raised in coastal area of Bangladesh.
