Climate change is rapidly becoming a major threat to Pakistan's food security, severely disrupting agricultural production across the country. The rising temperatures, erratic rainfall patterns, and increasing frequency of extreme weather events such as floods and droughts are causing widespread damage to crops, livestock, and fisheries. According to the Global Climate Risk Index 2023, Pakistan is ranked among the top five countries most vulnerable to the impacts of climate change, highlighting the severity of the issue (Germanwatch, 2023).
The 2022 floods, which devastated large parts of the country, caused agricultural losses worth $30 billion, destroying 45% of cropland in Sindh and Balochistan alone (World Bank, 2023). This has had a significant impact on food production and rural economies, as agriculture accounts for 22.7% of Pakistan’s GDP and employs approximately 37.4% of the workforce (Ministry of National Food Security, 2023).
The disruption of agricultural systems due to climate change is resulting in crop failures, livestock losses, and the collapse of fisheries. These consequences not only threaten food availability but also undermine rural livelihoods, pushing vulnerable communities deeper into poverty. Moreover, erratic weather patterns are exacerbating the challenges faced by farmers, particularly in terms of water availability for irrigation and the increased risk of crop diseases. This article explores how climate change is destabilizing Pakistan’s food systems and examines the urgent need for adaptation strategies, such as the adoption of climate-resilient crop varieties, better water management practices, and enhanced disaster preparedness, to mitigate these adverse impacts and safeguard food security for the future.
Impact of Climate Change on Agriculture
The effects of climate change on crop production in Pakistan are becoming increasingly evident, with rising temperatures, prolonged heatwaves, erratic rainfall, and extreme weather events severely disrupting agricultural output. Temperature extremes have been one of the most significant factors contributing to reduced crop yields. For instance, wheat, which is Pakistan's staple crop, faces a 10-15% decline in yields for every 1°C increase in temperature (PARC, 2023). The heatwave of 2023, where temperatures reached as high as 50°C in Sindh, resulted in a reduction of wheat production by 1.5 million tons (Pakistan Meteorological Department, 2023). Similarly, rice production in Punjab has been significantly affected, with Basmati rice yields dropping by 20% due to prolonged heat stress (University of Agriculture Faisalabad, 2023).
Droughts and erratic monsoons further exacerbate the situation. In 2023, Sindh experienced a severe drought that caused a 40% water shortage, forcing many farmers to abandon cotton and sugarcane crops (Sindh Irrigation Department, 2023). Conversely, the record monsoon rains of 2022 inundated 4 million acres of farmland, destroying 80% of crops in flood-hit districts (NDMA, 2022). In addition to these challenges, pest outbreaks, such as locust swarms between 2020 and 2022, devastated 3 million hectares of crops, leading to losses worth $2.5 billion (FAO, 2023). Similarly, pink bollworm infestations reduced Punjab's cotton output by 30% (Punjab Agriculture Department, 2023).
Beyond crop production, climate change is also threatening Pakistan's livestock and fisheries. Heat stress during the 2023 heatwaves caused a 15-20% reduction in milk production (L&DD Punjab, 2023). Water shortages in Balochistan forced nomadic herders to sell 50% of their livestock at distress prices (UNDP, 2023). Moreover, the fishing industry is facing a decline, with fish stocks in the Indus River falling by 35% due to habitat destruction and pollution (WWF-Pakistan, 2023). Mangrove deforestation in Karachi has reduced shrimp yields by 40%, putting the livelihoods of 500,000 fisherfolk at risk (IUCN, 2023).
Climate change is also severely impacting supply chains and food prices. The 2022 floods destroyed 13,000 km of roads, delaying the shipment of wheat and flour and causing a 50% spike in prices (PBS, 2023). Additionally, cold storage shortages are leading to 30% post-harvest losses of fruits and vegetables (Horticulture Board, 2023). This disruption in food supply chains has led to soaring food prices, with tomato prices reaching Rs. 300 per kilogram after the 2023 floods (State Bank of Pakistan, 2023). As a result, 7.6 million Pakistanis now face acute hunger, highlighting the growing food insecurity in the country (WFP, 2023).
Solutions for Pakistan
In response to the increasingly severe impacts of climate change on agriculture, livestock, and fisheries in Pakistan, various solutions can be implemented to mitigate these challenges and help the country adapt to changing climatic conditions. Climate-smart agricultural practices are essential in improving resilience. The development of drought-resistant seeds, such as heat-tolerant wheat varieties, has been a significant step taken by the Pakistan Agricultural Research Council (PARC) to ensure that crop yields remain sustainable even during periods of extreme heat (PARC, 2023). Moreover, adopting precision irrigation techniques, such as laser land leveling, can reduce water usage by up to 25%, optimizing water resource management and enhancing crop production during droughts (ICARDA, 2023).
For livestock and fisheries, adaptation measures are crucial. Installing shade structures and misting systems can help alleviate heat stress in cattle, ensuring that milk production and livestock health are not severely affected by extreme temperatures (L&DD Punjab, 2023). Additionally, community-led mangrove restoration projects have proven effective in reviving coastal fisheries, restoring marine habitats, and boosting the livelihoods of fisherfolk (IUCN, 2023).
On the policy front, expanding crop insurance to cover climate-related risks, such as those outlined in the State Bank of Pakistan’s Takaful Scheme, can provide financial protection to farmers against unexpected weather events (State Bank of Pakistan, 2023). Climate-resilient infrastructure is another critical intervention, with the need for flood-proof roads and storage facilities to mitigate the damage caused by extreme weather events. A National Early Warning System, developed through collaboration between the Pakistan Meteorological Department and UNDP, can help prepare communities for extreme weather events and reduce the associated risks (PMD-UNDP collaboration, 2023).
Lastly, global climate justice plays a vital role in addressing the climate crisis. Pakistan must actively demand loss and damage funding at international forums such as COP28 to help the country recover from climate-induced disasters. This funding is essential for restoring agricultural productivity and rebuilding infrastructure that is damaged by floods, droughts, and heatwaves, ensuring that Pakistan can continue to thrive despite the global climate crisis (Germanwatch, 2023).
Conclusion
Climate change is emerging as a critical challenge to Pakistan’s food security, with severe implications for agriculture, livestock, fisheries, and rural livelihoods. The rising temperatures, erratic rainfall, and extreme weather events such as floods, droughts, and heatwaves have already caused substantial damage, leading to crop failures, livestock losses, and the collapse of fisheries. With agriculture being a significant contributor to Pakistan's GDP and employment, these disruptions threaten not only food availability but also the livelihoods of millions of people. The 2022 floods alone caused $30 billion in agricultural losses, highlighting the scale of the crisis.
To address these growing challenges, a multi-pronged approach is essential. Climate-smart agricultural practices, such as the use of drought-resistant seeds and precision irrigation techniques, can help mitigate the adverse effects of climate change on crop production. Adaptation measures for livestock and fisheries, such as shade structures for cattle and mangrove restoration, are crucial for safeguarding these industries. On a policy level, expanding crop insurance, improving infrastructure, and developing early warning systems are key to building resilience against climate-induced shocks. Furthermore, Pakistan must advocate for climate justice and secure international funding to support recovery and adaptation efforts.
Ultimately, addressing the impact of climate change on food systems requires urgent and coordinated action at local, national, and global levels to ensure food security and protect the livelihoods of vulnerable communities in Pakistan.
