A climate change expert has warned that the anticipated El Niño climate phenomenon could worsen heat stress, drought and food insecurity in parts of Nigeria if preventive measures are not taken.

Dr Deborah Ishaku, who holds a PhD in Climate Change and Human Habitat and lectures at Gombe State Polytechnic, Bajoga, said the potential effects could include delayed rainfall, prolonged dry spells, reduced water availability and crop failure.

She noted that the expected El Niño conditions towards the end of 2026 and early 2027 could heighten climate-related risks, particularly for communities that depend heavily on rain-fed agriculture and have limited access to electricity and cooling facilities.

Ishaku identified Gombe State and other northern areas as places where the effects could have serious implications for farming, livestock production and access to water.

“Farmers need to prepare for the possibility of delayed rainfall and prolonged dry spells. These conditions can affect germination, crop development and yields, especially where farming depends entirely on rainfall,” she said.

She also cautioned that high temperatures, combined with dusty Harmattan conditions, could increase the risk of dehydration, heat exhaustion and heatstroke, particularly among children, older people, outdoor workers and those with limited access to cooling.

The expert recommended the use of drought-tolerant crop varieties and water conservation techniques to help farmers build resilience.
