Solar power generation and water pumping in barren mountains

Here, a solar powered system lifts water from lakes and rivers, transports it up unbelievably steep slopes to rural communities where it feeds into multi-use water systems. . Although the Khunjerab River provides plenty of water to those living in the valleys below, local farmers used to have no efficient way to get it up the mountainsides. But the installation of a hydraulic ram (hydro-ram) pump has changed that. It harnesses the pressure of fast-flowing water, such as. . New, hydro powered pumps now provide them with a constant supply and have turned previously barren landscape into blossoming fruit and vegetable farmland. [PDF]
