Assessment of the relationship between land use land cover and water quality status of the tropical watershed: a case of Batang Merao Watershed, Indonesia

Journal Title: Journal of Biodiversity and Environmental Sciences (JBES) - Year 2013, Vol 3, Issue 11

Abstract

Considering the vital role of Batang Merao Watershed as the source of water reservoir for most regional economic activities and the buffer zone of Kerinci Seblat National Park, this study aimed to investigate the relationship between LULC and water quality in the watershed. A total of 15 stations from selected catchments were collected and analyzed for bio-physic-chemical parameters for water quality analysis. The parameters were analyzed by using the Water Pollution Index (WPI) and STORET methods as the national standard of river water quality in Indonesia. LULC was analyzed by using GIS and remote sensing from Landsat image data for 2006 and 2011. Analysis of variance, correlation analysis, and stepwise multiple regression analysis were used to investigate spatial and temporal variations of LULC, water quality, and the relationship between them. The water quality study revealed that Batang Merao watershed was classified as lightly polluted (86.67%) and moderately polluted (13.33%) meanwhile, the STORET results indicated that about 80% of them were moderately polluted. The results also indicated that the study area was mostly dominated by mixed plantation (35%) and shrub/bush (21%), and also showed decreases in forest and increase in cultivated area (mix plantation and agricultural land). Statistical analysis showed several important results that One-way Anova indicated significant spatial differences; Pearson’s correlation showed the relationship between LULC and water quality parameters and regression analysis estimated the water quality parameter on changing LULC. The research could provide critical information on sustainable land use practice for water resource conservation for the tropical watershed.
