The impact of Climate Change on Himachal Pradesh

Himachal Pradesh, known for its breathtaking landscapes and snow-clad mountains, is facing an increasing threat from climate change. While the state typically receives significant snowfall during the winter months (December to February), the timing and amount of snowfall can vary considerably from year to year due to natural climate patterns. However, recent decades have shown a trend of drastic variations in temperature and precipitation. The decline in snowfall is affecting not only the picturesque beauty of the region but also the availability of water, which is crucial for agriculture, hydropower generation, and sustaining the state’s diverse ecosystems.

These changes are further compounded by rapid urbanization, deforestation due to road expansion, and global climatic shifts, all of which are altering the delicate balance of Himachal’s environment. The once-thriving apple orchards, a major contributor to the state’s economy, are struggling as warming temperatures push cultivation to higher altitudes. Farmers are facing uncertainty, and many are being forced to adapt to new crops or methods of irrigation due to erratic rainfall patterns.

Traditionally, Himachal Pradesh experiences heavy snowfall between December and February, replenishing glaciers and ensuring a steady water supply for the summer months. However, in recent years, snowfall has become erratic, delayed, and significantly reduced. The ongoing winter season has shown a worrying trend:

• Minimal rainfall and snowfall: Unlike past winters, this season has seen only 4-5 rainy days, leading to dry and warm conditions.
• Delayed snowfall: Higher temperatures have pushed snowfall events into late January or February, reducing the overall accumulation.
• Higher winter temperatures: Unusually warm temperatures have resulted in less snow formation, affecting glacial health and water availability. Notably, in January 2025, Shimla recorded an alarming 21°C, an unprecedented high for the winter season, further highlighting the impact of climate change.

Agriculture in Himachal Pradesh is heavily dependent on winter precipitation, as melting snow provides irrigation for crops. The decline in snowfall has caused:

• Water scarcity: The reduced snowpack due to climate change means that rivers and streams receive less water, significantly affecting apple orchards, wheat, barley, and vegetable cultivation. Local irrigation channels, known as “kuhls,” which derive water from rivers and khads, are drying up, exacerbating the water scarcity issue and putting further strain on agricultural practices.
• Shifts in cropping patterns: Shifts in cropping patterns have become a significant consequence of changing climate conditions. Farmers, especially in regions with traditionally cooler climates, are being forced to move away from their long-established crops, such as apples, which require specific chilling hours for optimal growth. As the temperatures rise and chilling hours decrease, these traditional crops no longer thrive as they once did. In response to this challenge, many farmers are turning to alternative crops like pomegranates, kiwis, and other varieties that require fewer chilling hours to grow successfully. This shift not only impacts the local economy but also alters the agricultural landscape, as farmers adapt to new conditions and explore crops that are more resilient to warmer climates.
  

One of the major contributors to climate change in Himachal Pradesh is large-scale deforestation, primarily driven by infrastructure projects such as the construction of four-lane highways. The loss of tree cover due to these developments has severe consequences for the environment. Trees play a crucial role in retaining moisture and maintaining the local climatic balance, but deforestation leads to soil erosion, loss of biodiversity, and increased land degradation.

Additionally, the ongoing road construction has resulted in heightened dust and pollution levels, which are impacting local weather patterns and worsening respiratory diseases among the population. The expansion of urban areas, especially in cities like Shimla, Manali, and Dharamshala, further exacerbates the situation. This rapid urbanization increases energy consumption and significantly alters the natural ecosystems, contributing to the overall environmental strain in the region.

Himachal Pradesh’s Chief Minister Sukhvinder Singh Sukhu has also linked the landslides in last monsoons to the ongoing four-laning work. He pointed out that the National Highways Authority of India (NHAI) engineers need to adopt a more scientific approach in cutting through the mountains to prevent further devastation.

Himachal Pradesh is not facing these changes in isolation—global climatic shifts are playing a crucial role:

• Rising global temperatures: The Earth’s average temperature has risen by 1.2°C since pre-industrial times, causing glaciers in Himachal to melt faster.
• Extreme weather events: Floods, landslides, and unseasonal rainfall have become more frequent due to climate change-driven weather anomalies.
• Reduced Western Disturbances: The weather systems that bring winter rainfall and snowfall to North India have weakened, leading to drier winters.

To combat these challenges, both the government and local communities must take proactive measures:

• Afforestation and Reforestation – Large-scale tree planting efforts can help restore ecological balance.
• Sustainable Tourism Practices – Encouraging eco-friendly tourism will reduce the environmental impact of increasing visitor numbers.
• Water Conservation Techniques – Farmers must adopt drip irrigation, rainwater harvesting, and efficient water management practices.
• Climate-Resilient Crops – Research into drought-resistant and temperature-tolerant crops can help farmers adapt.
• Strict Environmental Regulations – Enforcing laws on deforestation, construction, and pollution control will help minimize further damage.

The impact of climate change is not just environmental; it has serious socioeconomic implications:

• Livelihood Losses: Farmers and tourism-dependent communities are seeing reduced earnings, leading to economic instability.
• Migration Issues: Water scarcity and declining agricultural output are forcing people, especially youth, to migrate to urban centers in search of work.
• Health Risks: Rising temperatures and pollution contribute to respiratory illnesses, heat stress, and the spread of vector-borne diseases such as dengue and malaria.

Himachal Pradesh is at a crucial juncture, where the effects of climate change are becoming increasingly visible. Reduced snowfall, erratic weather patterns, and environmental degradation threaten not just agriculture but also tourism and overall livelihoods. Immediate action at both governmental and community levels is necessary to protect the state’s natural heritage and adapt to the changing climate. Only through sustainable development and conscious efforts can Himachal Pradesh continue to thrive in the face of climate challenges
