ABSTRACT

Being located in mountain region, Rawa Danau Nature Reserve is the only one wetland
area in the mountain region in Indonesis which formed very important component of its
biophysical and physical environment. With the decreasing control of the local
government and private agencies over the years, and rapid urban sprawl of the city,
many of the water bodies have been totally lost. This has been converted to wet rice
field cultivation and also expansion of illegal logging. One of our greatest
environmental challenges is to ensure an adequate supply and quality of water for
human use while maintaining the integrity of natural ecosystems. Rawa Danau has
become a main water supplier for the biggest steel industry in Indonesia for many years,
especially for Krakatau Steel Industry Area. This industry had make a reduction in the
carrying capacity of lakes and water channels. At first, the local government has not
bothered to either implement the existing laws or pay attention to the suggestions of
environmental challange in this regard. Understanding sub-urban growth impact in the
wetland environment is essential to understanding environmental change. Water also
links and integrates natural systems with human social systems. This paper presents
evaluation and asses changes in Rawa Danau wetland environment to understanding of
water dynamics and vegetation, and the impacts of human interventions and changing
environmental conditions on them using remote sensing approach.
