Earlier this year Geashpere and EcoDoc Africa released a great video about the impact of industrial tree plantations on water in the Jonkershoek Valley:
Plantation Trees and Water Use: Seventy years of Jonkershoek Paired Catchment Experiments
A Tour with Arthur Chapman
Plantations use significant amounts of water and South Africa is an arid country. In this documentary Arthur Chapman from One World Sustainable Investments (previously CSIR) takes us on a tour and shares with us the background of seventy years of hydrological research in the Jonkershoek Valley and how the paired catchment experiments work, and how much water trees really use. The intention of the documentary is educational, and to be used as a platform for further discussions.
