Karakteristik Lanskap Agroforestri Di Daerah Aliran Sungai Karang Mumus, Kalimantan Timur (Characteristics Of Agroforestry Landscape In Karang Mumus River Basin, East Kalimantan)

Abstract

East Kalimantan as largest province in Indonesia has big problems, inter a/ia are degradation farm, floods, flora and fauna destmction, and contribution to change of global climate and global warming. River basin zone of Karang Mumus broadly 32,196.3 ha is river basin in East Kalimantan with level of damage at first priority, at present there is marginal field area have larg~ 9, 106 ha. Purpose of this research was evaluate agroforestry landscape characteristic of Karang Mumus river basin. Based on spatial and temporal analysis that has done on Landsat! satellite image in 1992 and 2007, the composition of settlement area was increased out from 1,277.l ha became 1,926.9 ha, it means increased 649.8 ha (50.9%); abandon land was increased out from 119.5 ha became 712. 7 ha (495.5%); _shntbs land was increased out from 25,297.4 ha became 25, 762. 1 ha (1.8%). On the contrary, caver type and land use form the agriculture of wetland was decreased out from 1,034.8 ha became 807.8 ha (- 21.9%); dry/and agriculture was decreased out from 170.9 ha became 99.3 ha (-41.9%); and secondary forest was decreased out from 3,969.5 ha became 2,540.5 ha (-36.0%). Mostly of the lessen wetland of agriculture area, dry/and agriculture, and secondary forest were caused by the occurrence of land use changing !hat they became selllements, shmbs land, and abandon land Temporal analysis of Landsat image between 1992 and 2007 explained that land uses and cover types of selllement, abandon land, and shntbs lands were improved. Those changes have affected wetland agriculture, dry land agriculh1re, and secondary forest degradation.
