INTRODUCTION The agriculture sector is one of the most vulnerable ones to environmental change due to its susceptibility to variations in temperature and precipitation patterns, as well as naturally occurring climate limits, and the resulting barometric carbon dioxide (CO 2 ). Further- more, it is one of the few felds that both mitigates and encourages the sequestration of fossil fuel by-products while still leaving a signifcant global carbon footprint (around 13% in 2010). The Himalayan environment is extremely prone to the dire effects of imminent climate change. While the focus of recent research and debate has been on glacial retreat and its effect on downstream water discharge, there is growing evidence of climate change’s possible cascading impact on all related and satellite regions in the Himalayas. Because of its geological history and structural rock formation, the Himalayan ecosys- tem is rapidly approaching a state of disequilibrium, with visible changes in its resources and climate. The food systems are under increasing pressure from climate change, whose effects are becoming more noticeable. Among other effects, increasing temperatures, altered precipitation patterns, and extreme weather events are already lowering agricultural production and destabilising food supply chains. Millions of people are predicted to be at risk of hunger, malnutrition, and poverty by 2050 as a result of climate change (International Food Policy Research Institute 2022). Over 72 million people live in the Indian Hima- layan region, which is divided into ten states and 95 districts and covers a total area of 5 lakh square kilometres, accounting for roughly sixteen percent of the country’s total land area. The Himalayan eco- system is inherently vulnerable to natural disasters, which are susceptible to exacerbated occurrences of floods, droughts, and landslides triggered by drastic changes in climatic conditions, due to its high biological and socio-cultural diversity. HP is a mountainous state in northern India, located between latitudes 30 o 22’ 40” N and 33 o 12’ 40” N, and longitudes 75 o 45’ 55” E and 79 o 04’ 20” E in the western Himalayas. The state has a complex geological structure that dissects its topography into extreme altitudinal ranges from 350m to 6,975m above sea level. Because of the large elevation variations, it experiences a wide range of climates, from hot and humid tropical in the south to cold, alpine, and glacial in the north and east. The population of the state is 6.86 million, with approximately ninety percent of the population living in rural areas.

Cropping Season. Productivity. Temperature. Trend Analysis ABSTRACT Weather phenomena are infuencing temperature and rainfall patterns in the region, which impacts crop production. Therefore, the present study was conducted with the objective of ascertaining the effect of climate change on agricultural crop productivity in the district of Kinnaur. During the kharif season, results revealed that the maximum temperature rose at the rate of 0.02°C per year. After 1999, the maximum temperature remained above the long-term average except for the years 2001, 2002, 2005, 2008, 2011, 2013 and 2014, indicating an overall warming trend. During the rabi crop season, diurnal temperature increased by 0.02°C per year, which was statistically signifcant. As per the outputs from Mann Kendal Tests, an overall increased productivity trend was recorded for maize, barley and common millets, wherein wheat showed a decreasing trend of -0.014 t ha -1 year -1 . This means that the observed signifcant maximum variations in climatic parameters for rice are 35.6 percent, 15.4 percent for maize, and 9.0 percent for common millets. Non-signifcant variations were recorded for wheat, barley and ragi. © JBD 2022 J Biodiversity, 13(1-2): 14-23 (2022) Full text open access online (Since 2010)
