increased recruitment and growth of lowland species migrating upslope. Water scarcity can enhance tree mortality and decrease above-ground carbon stocks . The agricultural frontier of crops, such as potatoes or maize, is moving upwards , following the freezing level height upward displacement . Modelling exercises agree with the observed impacts in species, ecosystem processes, crop impacts and related pests and diseases  . Agricultural options are changing as a result of intra-seasonal temperature variation . Changes in the timing and amount of precipitation are also impacting agriculture  .
