Wheat production in northern Nigeria is coing under increasing pressure as rising temperatures linked to climate change disrupt traditional growing conditions, particularly in key farming zones such as Kano State.

For decades, wheat cultivation in the region has depended on the cool harmattan season, which provides the low night temperatures required for proper germination and grain development. However, shifting climate patterns are steadily eroding this narrow production window.

Shrinking cold season disrupts yields

Wheat is highly sensitive to temperature, especially during early growth stages. Historically, night temperatures in Kano ranged between 13°C and 15°C during the 1980s and 1990s. Today, average minimum temperatures have risen above 18°C, significantly affecting crop performance.

According to research aligned with findings from the Intergovernmental Panel on Climate Change, wheat yields can decline by approximately 6% for every 1°C increase in temperature. This makes even small changes in climate conditions highly consequential for farmers.

Agricultural experts note that warmer nights and shorter cold periods are weakening germination, reducing stem strength, and lowering grain yields across the region.

Farmers face declining productivity

The impact is already visible at farm level. In communities such as Kura and surrounding areas, farmers report a sharp drop in output over recent years.

Fields that once produced high yields are now delivering significantly smaller harvests, with some farmers reporting output declines of more than 50%. Poor germination and stunted crop growth have become increasingly common.

The unpredictability of seasonal patterns has also disrupted traditional planting calendars, making it difficult for farmers to time production effectively.

Adaptation strategies remain limited

In response to rising temperatures, some farmers are attempting to adapt by adjusting planting schedules or increasing irrigation to cool soil conditions. However, these measures offer only partial relief.

Water scarcity and rising fuel costs for irrigation systems are limiting the effectiveness of these strategies. Earlier planting, once considered a viable adjustment, has also become unreliable as temperature fluctuations persist.

Food security risks intensify

The decline in wheat production has broader implications beyond local farming communities. Nigeria remains one of Africa’s largest wheat importers, relying heavily on global markets to meet domestic demand.

Reduced local production increases exposure to international price volatility and supply disruptions, particularly during periods of global instability. This was highlighted during the Russia-Ukraine war, which significantly affected global wheat supply chains.

Experts warn that continued climate pressure on domestic wheat production could lead to higher food prices, increased import dependence, and greater vulnerability in national food systems.

Need for climate-resilient solutions

Efforts are underway to address the challenge through the development of heat-tolerant wheat varieties by international research institutions. However, scaling these solutions to reach smallholder farmers remains a major constraint.

Improved extension services, better access to climate information, and investment in climate-resilient agricultural systems will be critical to sustaining wheat production in northern Nigeria.

Outlook: a changing future for wheat farming

The situation in Kano reflects a broader trend across the Sahel region, where climate change is reshaping agricultural viability. As temperature patterns continue to shift, traditional crops such as wheat may require significant adaptation — or risk becoming increasingly unviable in their current growing zones.
