This World Bank website contains three case studies that outline important environmental and socio-economic issues faced by geothermal developments around the world. The case studies cover environmental impacts relating to indigenous tribal concerns in Mt. Apo, Philippines; the negative effects of geothermal development on valued thermal features due to resource mis-management at Rotorua, New Zealand; and the development of a geothermal field in a National Park in Olkaria, Kenya.
