Impact of Land-use Change on Dengue Hemorrhagic Fever in Kolaka District, Southeast Sulawesi Province, Indonesia

Abstract

Land use change is contributing to the emergence of zoonotic diseases in the community. And can cause an increase in the spread of the virus through arthropods. This study aimed to determine the association of land use factors and dengue hemorrhagic fever in Kolaka District, Southeast Sulawesi Province, Indonesia. The secondary data obtained from various governments of Indonesia were used for this study. Data of dengue hemorrhagic fever from Ministry of Health of Republic Indonesia. Land use data is derived from the classification of Citra Landsat 8 on a scale of 1: 250,000 from 2010 to 2020. The Spearman rank correlation test was used to examine the relationship between land-use change and the incidence rate of dengue hemorrhagic fever. The results of this study In Period 2010-2015 is a correlation between Agriculture with dengue hemorrhagic fever ( α = 0.812, p <0.05), and water bodies with α =0.812. The area of agricultural land is increasing every year; in 2010, only 3.32% increase to 51.08% in 2015. Furthermore, in period 2016-2020 is a correlation between Forest with dengue hemorrhagic fever (α = 0.900, p <0.05), and Settlement (α = -0.900, p <0.05). Our findings could be used to improve the understanding of land-use change and dengue hemorrhagic fever in the Kolaka district and provide information on land use that does not damage the environment.
