Impacts of Coastal Land Use Changes
on Mangrove Wetlands at Sungai Mangsalut
Basin in Brunei Darussalam
Shafi Noor Islam and Umar Abdul Aziz Bin Yahya
Abstract The chapter evaluates the rapid changes of coastal landscape and expansion and asymmetrical land use or cover changes in Sungai Mangsalut basin area in
the coastal region in Brunei Darussalam. It is revealed that the coastal land use
changing pattern of Sungai Mangsalut basin area is rapidly expanding due to natural
environmental calamities, increasing population pressure and economic development and consequently led to the conversion of water bodies, cultivated lands, natural forest vegetation or open spaces in buildup areas. The exploitation of settlement
and urbanization size through inhabiting the river mouth and low lying areas and
clearing of coastal mangrove and coastal salt marches of vegetation without a corresponding expansion to infrastructures resulted in a wide range of environmental
issues and risks such as severe pollutions, significant decrease of water bodies along
with greenery and uncontrollable growth of settlement. In other words, these issues
existed because the authority is unable to cope with the swift changing situations
due to their internal resource constrains and management limitation. Hence, for that
reason, this paper also highlights the consequences of the coastal wetland and basin
landscapes changes in Sungai Mangsalut basin area in the coastal region in Brunei.
The objective of this chapter is to analyze the coastal environmental impacts of the
area surrounding Sungai Mangsalut (Mangsalut River). Also to identify the factors
influence the degradation of the Sungai Mangsalut in the present time.
