Rising Temperatures and Water Scarcity in Agriculture: A Growing Threat to Pakistan’s Agri Sector

Rising Temperatures and Water Scarcity: A Challenge for Pakistan’s Agriculture

Pakistan’s agriculture sector, the backbone of the economy, faces an alarming threat from climate change. Rising temperatures and water scarcity have significantly impacted crop yields, particularly wheat, which is a staple food for millions.

The Impact on Wheat Production

Wheat plays a crucial role in Pakistan’s agricultural economy, contributing to rural employment and GDP. The government has implemented various initiatives, such as planting campaigns, subsidies, and support pricing, to ensure sufficient production. These efforts led to a record wheat production of 27.4 million tonnes in the 2020-21 season. However, with wheat consumption expected to reach 31.2 million tonnes in 2024-25, Pakistan’s reliance on imports is growing.

Climate Change and Agricultural Vulnerability

Agriculture in Pakistan rising temperatures and water scarcity in Pakistan is highly dependent on weather patterns. Rising temperatures and erratic rainfall reduce soil moisture, leading to lower yields. Additionally, water scarcity limits irrigation, putting further stress on farmers.

Key Challenges in Pakistan’s Agriculture Sector

Pakistan’s agriculture sector faces a myriad of challenges, primarily driven by climate change. These challenges threaten food security, economic stability, and rural livelihoods. Among these, increased heat stress on crops, reduced water availability, higher risks of droughts and floods, and declining soil fertility stand out as major concerns.

1. Increased Heat Stress on Crops

With global temperatures rising, heat stress is becoming a significant threat to crops in Pakistan. Wheat, rice, maize, and sugarcane—major staple crops—are particularly vulnerable. Higher temperatures lead to shorter growing seasons, lower yields, and reduced quality of produce. Heatwaves, occurring more frequently, exacerbate this problem by causing premature ripening and reduced grain weight.

2. Reduced Water Availability for Irrigation

Water is the backbone of agriculture, and its scarcity poses a severe challenge. Pakistan relies heavily on the Indus River system, but decreasing glacier reserves, erratic monsoon patterns, and over-extraction of groundwater have drastically reduced water availability. Traditional flood irrigation methods waste significant amounts of water, making conservation efforts more critical than ever.

3. Higher Risk of Droughts and Floods

Pakistan experiences extreme weather fluctuations, leading to alternating droughts and floods. Prolonged droughts deplete groundwater reserves, reduce soil moisture, and lead to desertification in some regions. On the other hand, floods destroy crops, erode fertile soil, and damage critical infrastructure, further exacerbating food insecurity.

4. Declining Soil Fertility

Excessive use of chemical fertilizers, mono-cropping, and overgrazing have led to declining soil fertility in many parts of Pakistan. The depletion of essential nutrients, soil erosion, and salinity issues contribute to lower crop productivity. If left unaddressed, this trend will make it increasingly difficult for farmers to maintain their yields.

Solutions to Combat the Crisis

1. Improved Irrigation Techniques

Adopting modern irrigation techniques is crucial for water conservation. Drip irrigation, which delivers water directly to plant roots, minimizes wastage and increases efficiency. Rainwater harvesting systems can also supplement irrigation during dry spells. Laser land leveling is another innovative practice that ensures even water distribution across fields.

2. Climate-Resilient Crops

Developing and promoting climate-resilient crop varieties is essential for sustaining food production. Drought-resistant wheat, salt-tolerant rice, and heat-resistant maize can help mitigate the impact of climate change. Research institutions and seed banks should focus on breeding high-yield, stress-tolerant crops to support farmers in vulnerable regions.

3. Efficient Water Management

Government policies must prioritize sustainable water use. This includes building small dams to store rainwater, improving canal infrastructure to reduce water losses, and enforcing regulations on groundwater extraction. Farmers should be encouraged to adopt water-saving techniques such as alternate wetting and drying (AWD) for rice cultivation.

4. Technology Integration

Precision agriculture, which uses data analytics, remote sensing, and automated irrigation systems, can optimize resource utilization. Mobile applications providing real-time weather forecasts, soil health monitoring, and pest alerts can empower farmers with the knowledge needed to make informed decisions.

5. Public Awareness and Farmer Education

Educating farmers on climate-smart agricultural practices is critical for long-term resilience. Training programs on crop diversification, organic farming, and soil conservation techniques can help farmers adapt to changing conditions. Government and private sector initiatives should work together to facilitate knowledge-sharing through agricultural extension services.

The Future of Pakistan’s Agriculture Sector

If these strategies are effectively implemented, Pakistan can overcome climate-related challenges and reduce its reliance on wheat imports. A national approach combining innovation, policy reforms, and farmer participation is crucial for securing the future of agriculture. Sustainable farming methods, coupled with investments in research and infrastructure, will pave the way for a resilient agricultural system.

Final Thoughts

Pakistan’s agriculture sector stands at a crossroads. Rising temperatures and water scarcity pose serious threats, but informed policies and modern solutions can safeguard the country’s agricultural backbone. Investing in sustainable farming today will ensure food security for future generations. Collaborative efforts between the government, research institutions, and farmers will be key to addressing these pressing challenges and transforming the agricultural landscape for the better.
