We spend our last day in Helambu talking to the few remaining yak herders in Langtang National Park. Changes are being observed in grazing pastures/grasslands, which are reducing in area or being taken over by forests. Water sources are disappearing in the highlands, leaving old livestock/cattle sheds in grazing pastures without water. Unable to shift from ancient grazing routes, pastoralists are responding by artificially growing grasslands and using pipes to bring water to fill dried-up ponds in the pastures. But how can the livelihoods of pastoralists be secured in a changing climate when there is no consensus on who is responsible to solve this problem, as range land expert Dr Uttam Babu Shrestha questions?
