Impacts of human activities and hydrological processes on monthly riverine nitrate sources and transport in the Agro-Pastoral ecotone

Key Points

• Monthly riverine nitrate sources show significant variation due to human activities and hydrological processes, impacting nearby ecosystems.
• The highest nitrate concentrations were recorded during the wet season, with human influence accounting for approximately 60% of these pollutants.
• Assessment of hydrological processes involved in nitrate transport highlights the interconnectedness of land use and water quality outcomes.
• The findings highlight the need for sustainable agricultural practices to mitigate adverse effects on water systems and protect ecological balance.
