In the barren, lunar landscape of Ladakh, life throws up the harshest questions. Like in the winters, when temperatures plunge to –30 degree celsius and icy winds from the Himalayas rattle humans and animals to the bones. Or in the summers, when all the ice melts and the ground water runs off, leaving a parched valley gasping for a drop. For 51-year-old Sonam Wangchuk—one of India’s most famous innovators who even has a popular Bollywood character modelled on him—it’s now his life’s mission to find answers to the challenges. And to show Ladakh’s younger generation how to do it.
