Summary
Apply remote sensing and GIS technology in detecting the change of agro-forestry land use in Con Cuong district, Nghe An province
LANDSAT images in 1976, 1992 and 2000 were analyzed with the help of WINCHIP software. Land use map for forest and agricultural coverage from 1076 to 2000 were created. Result: agricultural land has increased by 3829 ha and forest land has decreased with 4853 ha during 24 years. Deforestation took place often within 1500 m distance from main rivers and streams. The present research may help for policy makers to formulate appropriate management policies for land use to improve economic social conditions in mountainous areas in Con Cuong as well as in other high land districts in Vietnam.
