Impact of Human Activities and Natural Processes on the Seasonal Variability of River Water Quality in Two Watersheds in Lampung, Indonesia

Abstract: This study identified seasonal water quality characteristics in two adjacent mountainous rivers (Sangharus and Sekampung Hulu Rivers) in Lampung, Indonesia and determined the impacts of fertilizer application on river chemistry as a result of social forestry management. In 2016, we measured water chemistry and conducted a farmers’ questionnaire survey to obtain information on fertilizer application. The water quality results indicated that several parameters, including nitrate (NO3) and phosphate (PO4), were s… Show more

“…To date, research on river water quality has largely focused on the investigation of 'good' status across all levels of water quality at varied scales. These include small catchment scale (less than 100 km 2 ) (Freni et al, 2012;Dewi Yustika et al, 2019), large catchment scale (1.8 million km 2 ) (Yang et al, 2015) and worldwide scale (Khan et al, 2017). It is however unclear whether these study conclusions are transferable to high status rivers.…”

“…Sustainable intensification to increase food security will require proper water management in addition to the use of high-yielding varieties and agronomic practices [117,118]. To increase water availability and mitigate the effects of drought in agricultural areas, irrigation management will need to be improved, as will the management of proper planting time [119][120][121][122]. Water is responsible for increased agricultural production, so it is crucially important to improve irrigation and water use efficiency [123].…”

“…The river water condition is determined by the relationship between climate, anthropogenic activities and natural processes [1]. Land use change as a result of human activities, urban development, and industry has impacts on high surface runoff and floods [2,3].…”
