Soil erosion control in tree plantations on steep slopes: Runoff water andsediment trapping efficiency of riparian grass buffer in mountainoushumid tropics

Riparian grass buffers reduce the velocity of water flowing over the soil surface during storms, capturing surface runoff (SR) and trapping soil particles eroded from cultivated slopes. Rarely quantified under steep slope conditions (>45 %), this phenomenon probably occurs in many mountain agroecosystems in the humid tropics. In Southeast Asia, teak plantations are often established on […]

Village settlements in mountainous tropical areas, hotspots of fecal contamination as evidenced by Escherichia coli and stanol concentrations in storm water pulses

Little is known about the contribution of villages to the fecal contamination of surface water in tropical rural areas. This study, published in the journal Environmental Science & Technology, documents E. coli and stanol concentration levels in surface runoff, and tracks the origin of the fecal contamination during flood events.

Effects of climate and anthropogenic changes on current and future variability in flows in the So’o River Basin (south of Cameroon)

Due to climate and environmental changes, sub-Saharan Africa (SSA) has experienced several drought and flood events in recent decades with serious consequences on the economy of the sub-region. In this context, the region needs to enhance its capacity in water resources management, based on both good knowledge of contemporary variations in river flows and reliable […]
