Abstract

Monitoring land cover change is important to be done in order to understand changing mechanism and to model impacts of the change to environment and ecosystem in different scale.  Research on change detection of the Tondano watershed for the period of 1989-1999 showed that the land cover has changed due to agricultural activity and urbanization (Prenzel, et al, 2006). Land cover change of the Tondano Watershed contributed to the flooding and landslide disasters in Minahasa and Manado in the early of 2014. This research was conducted to compare land cover of the Tondano Watershed between the period of 2002 and 2015 using remote sensing data and Geographical Information System (GIS). Change detection method, post classification comparison was used to gather information on land cover change in the Tondano Watershed. Results showed that there was a significant change in the land cover within thirteen years. There was a decrease of forest, paddy field and volcano areas and an increase of agriculture, residential and water body areas. Forest has been converted to dry land agriculture; paddy field area has been converted to agriculture and residential areas. An increase of residential area was caused by conversion of agricultural and paddy field areas located nearby Manado City.

Abstract

This qualitative study was analyzed using semi-detailed method is based on the assessment of data and information that is more accurate, can be quantitative. Primary data was collected through interviews with the stakeholders starting from the government officials, the academics and community leaders to get information about important issues emerging in Bolaang Mongondow. Secondary data collected from various government agencies and institutions or personnel associated with the research. The results showed that the mining activities in BolaangMongondow both for exploration and exploitation cause negative impacts by 50%. Starting from the conversion of land that have growing increasingly by time which can certainly bring problems in the future. The implication of uncontrolled agricultural land conversion can threaten food supply capacity and even in the long term can cause social harm. The mining activities, plantation and cultivation will lead to fragmentation of forest landscapes. Forest fragmentation will cause the forest to be smaller in which to live for animals and resulted in less food available for wildlife. There are 6 rivers in Bolaang Mongondow indicated that some parameters that are already above the value of standard quality. They are River Toraut located in the Sub-district of West Dumoga, Totabuan River, Tombolango River located in the Lolak Sub-district, upstream and downstream sections of Wineru River and Nonapan River located in Poigar Sub-District. In addition, natural disasters often occur in Bolaang Mongondow including floods and landslides. This natural disaster resulted in tremendous losses for the community. This study concludes that need to enactment of Regions to regulate mining activities in the area. And also there are should be intensive supervision from the institution concerned.
