Exploring the nexus between hydroclimatic variability, population growth, land use land cover change, and long-term upper Nyong Basin River chemistry (Central Africa rainforest).

ABSTRACT: Hydrological and hydrogeochemical functioning of rivers depends on the relationship between climatic variability, land use and land cover change (LULCC), and population dynamics. However, there is a scientific gap on this relationship in the humid tropical zone of Central Africa. This study aims to fill this gap by examining the link between hydroclimatic variability, population growth, LULCC, and river water chemistry in the upper Nyong basin (UNB). Atmospheric temperature and rainfall data were obtained from Climatic Research Unit gridded Time Series 4.07 (CRU TS 4.07), in Google Earth Pro 7 software. Demographic data were obtained by projection based on the 1976, 1987 and 2005 censuses, assuming population increase as in the past. Land use and land cover (LULC) maps for 2005-2020 period
