CARBON GAS CALCULATION AS A RESULT OF LANDUSE CHANGE BY USING MULTI TEMPORAL LANDSAT TM 7 IMAGES OF 1992-2007 IN LIMA PULUH KOTA REGENCY

Abstract

The objective of this research is to map landcover change, and released
carbon emission in Lima Puluh Kota Regency and Payakumbuh Municipality since
1992 – 2007 by using rapid assessment approach based on Multi Temporal
Landsat TM 7 Images (1997-2007) of the Remote Sensing Technology. The findings
present nine landcover classifications identified in Lima Puluh Kota Regency and
Payakumbuh Municipality. The current largest landcover change areas are
Primary Forest, and Secondary Forest. Land cover change in Lima Puluh Kota
Regency and Payakumbuh Municipality during the period of 1992 – 2007 indicates
even distribution of biomass content in both areas. In total, land cover change
since 1992 - 2007 in Lima Puluh Kota Regency and Payakumbuh Municipality
contributes to the release of 1,141,458,592 tons of carbon or 76,097,239 tons of
carbon per year, with 4,185,348,171 tons of CO2 emissions. The data suggest that
during that period, both areas contributed 279,023,209 tons of CO2 as greenhouse
gas affecting the Earth’s temperature which then led to global warming.
