Impact of Climate Change on Pakistan's Livestock Sector

In Pakistan, the visible face of climate change is often portrayed through dramatic events such as glacial melt, erratic monsoon rainfall, and devastating floods. While these shocks capture public and policy attention, a quieter yet more persistent crisis is unfolding within the livestock sector. This hidden dimension of climate change is steadily eroding rural livelihoods, weakening food systems, and posing emerging risks to public health. The increasing incidence and spread of livestock diseases, which are caused by changing temperature regimes, humidity patterns, and ecological disruptions represent a critical but under-recognized challenge.

Livestock remains the backbone of Pakistan’s rural economy, contributing approximately 60.6 percent to the agriculture sector and around 14 percent to national GDP, according to the Pakistan Economic Survey 2022–23. More than 8 million rural households depend on livestock for income, nutrition, and financial resilience. Cattle, buffalo, sheep, and goats serve as vital assets, providing milk, meat, draft power, and a buffer against economic shocks. However, the sustainability of this sector is increasingly threatened by climate-induced stressors.

Rising temperatures are intensifying heat stress in animals, reducing feed intake, fertility, and milk production. At the same time, changing rainfall patterns and increased humidity are creating favorable conditions for the proliferation of disease vectors such as ticks, mosquitoes, and flies. These vectors facilitate the spread of infections including foot-and-mouth disease, hemorrhagic septicemia, and parasitic infestations. Moreover, prolonged droughts and floods weaken animal immunity by limiting access to quality feed and clean water, further increasing disease susceptibility.

As highlighted by recent studies, climate change is effectively reshaping the epidemiology of livestock diseases in Pakistan. Without timely adaptation measures, this evolving threat could significantly undermine rural incomes, disrupt food supply chains, and intensify poverty in already vulnerable communities.

Climate-Induced Livestock Vulnerability in Pakistan

Climate change is exerting a profound and multifaceted impact on livestock health in Pakistan, with heat stress emerging as one of the most immediate physiological challenges. Rising ambient temperatures, coupled with increasing frequency of heatwaves, directly impair animal metabolism and immune function. Heat-stressed animals exhibit reduced feed intake, lower fertility rates, and diminished milk and meat productivity. High-yielding exotic breeds such as Holstein Friesians are particularly susceptible due to their limited adaptability to tropical climates. This physiological strain weakens disease resistance, making livestock more vulnerable to opportunistic infections and exacerbating farm-level disease burdens.

Simultaneously, climate change is reshaping the epidemiology of vector-borne diseases by altering the habitats and life cycles of disease-carrying organisms. Warmer temperatures and fluctuating humidity levels have facilitated the expansion of ticks, mosquitoes, and flies into new ecological zones. This shift has heightened the risk of zoonotic diseases, notably Crimean-Congo Hemorrhagic Fever (CCHF), which has shown increasing incidence in Pakistan. The rise in tick populations during prolonged hot and dry spells has intensified disease transmission between animals and humans, posing serious public health concerns. Additionally, the potential emergence of diseases such as Rift Valley Fever underscores the growing threat posed by changing vector ecology in the region.

Extreme weather events further compound these challenges. The devastating floods of 2022 led to massive livestock mortality and displacement, while also creating conditions conducive to disease outbreaks. Contaminated water sources and degraded feed supplies triggered the spread of bacterial infections and parasitic diseases, including hemorrhagic septicemia and foot-and-mouth disease. These outbreaks placed immense pressure on already strained veterinary services. In contrast, recurrent droughts in regions such as Balochistan and Tharparkar result in acute shortages of water and pasture, forcing pastoralists to migrate. This movement increases herd interactions, facilitating the spread of transboundary animal diseases. Moreover, chronic malnutrition during drought periods weakens animal immunity, perpetuating a cycle of disease susceptibility, productivity loss, and rural economic vulnerability.

Zoonotic Risks and the Imperative for a One Health Strategy in Pakistan

The growing burden of zoonotic diseases represents a critical intersection between livestock health and public health in Pakistan. Globally, more than 60% of emerging infectious diseases originate from animals, and Pakistan’s dense human-livestock interface significantly amplifies the risk of disease spillover. Individuals working near animals including farmers, butchers, veterinarians, and dairy handlers face continuous exposure to pathogens, often in environments with limited biosecurity. The recent experience of the COVID-19 pandemic demonstrated how a localized zoonotic transmission can escalate into a global crisis with devastating health and economic consequences. In Pakistan, the rising incidence of Crimean-Congo Hemorrhagic Fever and the persistent threat of Avian Influenza (H5N1) in poultry systems highlight the urgency of strengthening preventive mechanisms. Without proactive intervention, these risks could evolve into large-scale outbreaks, further straining already fragile healthcare and veterinary systems.

Addressing this complex challenge requires a fundamental shift toward the One Health framework, which emphasizes the interconnectedness of human, animal, and environmental health. Rather than operating in silos, institutions must adopt coordinated, cross-sectoral strategies that integrate disease surveillance, environmental monitoring, and public health planning. Evidence suggests that the cost of prevention through such integrated systems is significantly lower than the economic fallout of a major epidemic, reinforcing the need for early investment and institutional alignment.

Strengthening Pakistan’s capacity to manage zoonotic risks demands targeted interventions across multiple domains. First, veterinary infrastructure must be expanded by increasing the availability of trained field veterinarians, establishing mobile clinics, and upgrading diagnostic laboratories to enable rapid disease detection. Second, the development of real-time, climate-sensitive surveillance systems leveraging digital technologies can facilitate early warning and targeted immunization campaigns. Third, promoting climate-smart livestock practices, including improved housing, biosecurity protocols, and resilient fodder systems, can reduce disease exposure under extreme weather conditions. Finally, investment in research and innovation is essential. Institutions such as University of Agriculture Faisalabad can play a pivotal role in developing locally adapted vaccines, diagnostic tools, and evidence-based policy solutions tailored to Pakistan’s unique agro-ecological conditions.

Conclusion

Climate change is no longer a distant environmental concern but an immediate and systemic threat to Pakistan’s livestock sector, with far-reaching implications for rural livelihoods, food security, and public health. The evidence presented in this article underscores how rising temperatures, shifting precipitation patterns, and extreme weather events are not only reducing animal productivity but also accelerating the spread and emergence of infectious and zoonotic diseases. This evolving risk landscape is particularly alarming in a country where millions of rural households depend on livestock as a primary source of income and nutrition.

The convergence of animal health challenges with human health risks highlights the urgency of adopting integrated and forward-looking policy responses. Strengthening veterinary infrastructure, investing in climate-resilient livestock practices, and developing real-time disease surveillance systems are no longer optional they are essential pillars of sustainable agricultural development. Equally important is the institutionalization of the One Health approach, ensuring coordination between agricultural, health, and environmental sectors to effectively manage complex disease dynamics.

Ultimately, building resilience in Pakistan’s livestock sector requires a proactive rather than reactive strategy. Policymakers, researchers, and practitioners must work collaboratively to anticipate risks, invest in innovation, and empower farming communities with the knowledge and tools needed to adapt. Without decisive action, the hidden crisis of livestock diseases will continue to deepen, undermining both economic stability and public health outcomes.
