Observed climate-driven impacts on mountain ecosystem services, agriculture and pastoralism are largely negative in most mountain regions . Agriculture has been negatively affected through increased exposure to hazards such as droughts and floods, changes in the onset of seasons, the timing and availability of water, increasing pests and decreasing pollinator diversity, which in turn have negatively influenced overall food production, dietary diversity and the nutritional value of food . Negative climate impacts on pastoralism, such as drought- induced degradation of rangelands and pastures, have affected livestock productivity and the livelihood of pastoralists, while other non-climatic factors, such as land use change and management, also play a role .
