Impact of Climate Change on Mountain Horticulture
The ecosystems which are most vulnerable to the specter of climate change are high mountain areas such as Himalayas. In Northwestern Himalayan region covering the states of Himachal Pradesh, Jammu, and Kashmir besides Uttrakhand, very limited studies on climate change have been done. Hence, considering the past and present climatic trends, future climatic scenario of Himachal Pradesh has been studied. Himachal Pradesh is a mountain state of north India, located between 30° 22′ 40″ to 33° 12′ 40″ N latitude and 75° 47′ 55″ to 79° 04′ 20″ E longitude. It has large dissimilarity in physiographic features and experiencing varied changes in warming and precipitation due to global warming, which will be both negative and positive, to horticulture production. Future climate will determine the suitability of fruit crops to their current locations. Climatic conditions likely to occur in Himachal Pradesh during 2021–2050 are analyzed and termed as mid-period compared to baseline period (1960–1990) using HADRM3 model under scenario A1B. The climatic parameters included are maximum temperature (Tmax), minimum temperature (Tmin), and rainfall. District-wise changes, likely to occur, in the above parameters and their implications to fruit cultivation have been discussed in this chapter.
