Grazing time in the mountain will be shorter with the increase in temperature. Excessive rains will cause runoff and erosion. Erosion also causes mountain meadows to decrease
It will depend on the local surrounding, local vegetation and which type of weather change will be brought to the location by climate change (warmer, colder, dryer, wetter). Most places are predicted to get warmer, with changes in precipitation patterns. With increased temperature we could see a higher tree-line, which essentially decreases the total area capable of sustaining grazing. Less total grazing area will increase the pressure on the area remaining, potentially contributing to over-grazing, erosion and other negative effects on the ecosystems. Human population increase will also infer that more animals will be needed to sustain the population, and with more animals comes even higher pressure on local systems.
It depends on which mountain region we are talking about. It is becoming much drier in many regions, which will make grazing difficult or even impossible. In the Alps, this problem already exists on many areas of the Southern Alps (Italy), where the cows can no longer be adequately supplied with water. Water is brought to the alpine pastures by helicopter. It cannot be the future. Extreme weather events such as heavy snow and heavy rain will also increase soil erosion. Overall, climate change is likely to have a significantly negative impact on the grazing of the mountainous areas.
