Evaluation of Land Use Change in The District Dhamasraya

Abstract

Since Dharmasraya Regency, West Sumatra, Indonesia was established in 2004, has an impact on land-use change. Changes in land use can be analyzed quickly through the interpretation of satellite imagery. The methodology used is the analysis of spatial and temporal changes in land use on satellite images captured in 2004, 2009 and 2014. The result showed that there has been a decline in forest area since Dharmasraya 2004 until 2014. The forest area which was originally in 2004 area is 161.141 ha, in 2009 decreased to 109.056 ha, and in 2014 decreased again to 94.146 ha. This decrease occurred in forest and non-forest areas (areas other use). In 2014, the forest area is available on the forest area is only 22.8%, less than the minimum limit of 30% in a region. A decrease in forest area is partly due to land clearing for plantations and other uses. Instead of the results of this study also showed that, an increase in area plantation/mixed-garden. In 2004 the area plantation/mixed-garden is 115.831 ha. In 2009 increased to 148.149 ha (27.9%) and in 2014 increased to 168.730 ha (13.89%). In 2014, the area plantation/mixed-garden in the non-forest area is 142.481 ha (84.4%) and the forest area is 26.249 ha (15.6%). Supervision required to cope with the increased use of protected areas. This area has been used for plantation / mixed-garden covering an area of 1.127 ha, 816 ha of open land and dry land 17 ha. This area should be restored function into protected forest.
