Climate change impacts on food, fibre and ecosystem products will be highly variable across mountain regions   . In some regions, tree crops that are cultivated at certain elevations may reach the limit of their agroclimatic plasticity, for instance for crop types that require winter chills and where projected growing conditions are too warm . In the European Alps, agricultural production in some areas may benefit from temperature rises, as total productivity in grasslands is projected to increase , whereas some areas in Asia and South America heavily dependent on glacier- and snow-fed irrigation will be at risk of food insecurity . In a study in Eastern Pamir, Mętrak et al.  found that summer droughts and water changes lead to functional transformations of the wetland ecosystems which can affect food security of the local population. Climate change affects the phenology of plants (Harish et al., 2012; Gaira et al., 2014; Maikhuri
