Temperature and precipitation largely determine the weather and climatic conditions at a place. These determinants are subject to a great change following the prevailing unsustainable developmental practices. Therefore, the present study analyses the temperature and precipitations conditions in a hilly terrain of one of the fastest developing regions in the middle Himalayan Mountains. The results reveal an increasing trend of 0.23ºC per decade and 0.64º per decade respectively in Tmax and Tmin between 1973 and 2022 in Ramgarh block of Nainital district, Uttarakhand, India. However, an overall increasing trend of decadal rainfall has been observed over the past five decades in the region. The study area recorded 131 days of high-intensity rainfall over the past 5 decades. These conditions have given rise to major threats no to subsistence farming systems and food and livelihood security in the densely populated rain-fed middle Himalayan Mountains.
