Displaced by devastating floods, Nigerians are forced to use floodwater despite cholera risk – Climate emergencies are a humanitarian and health crisis which affect us all.

As Nigeria experiences complex and unpredictable climate risks which have led to extreme weather events such as the flooding in 34 out of the 36 states in the country, the compounding of existing vulnerabilities and inequities is putting millions of our people at immediate risk for disease, famine and death.

More than 2.5 million people in Nigeria are in urgent need of structured humanitarian assistance, 60% of which are children, and with 1.3 million people displaced, there is a growing and heightened risk of waterborne diseases, drowning and malnutrition. The rise in cases of cholera is particularly worrisome as the WHO recently warned of the shortage of cholera vaccines, due to a strained global supply during a time of unprecedented rise in outbreaks worldwide, leading to the temporary suspension of the two-dose strategy.

According to UNICEF’s Children’s Climate Risk Index CCRI, Nigeria is now considered at ‘extremely high risk’ of the impacts of climate change, ranking second out of 163 countries. Children of ‘extremely high risk’ countries often face exposure to multiple climate and environmental shocks, paired with underlying child vulnerability, which my Wellbeing Foundation Africa midwives, nurses and healthcare teams are working daily on the frontline to mitigate by providing essential grassroots community-based Mamacare360 Maternity programming and intensified WASH services through our Reckitt, Dettol Nigeria, WBFA Hygiene Quest Curricula.

The burden of climate-related health risks is inequitably and unequally distributed, and its worsening impacts are increasingly affecting the foundations and pillars of human health and wellbeing. Looking ahead, I welcome the African Summit which will be held alongside COP27 at Sharm El Sheikh, Egypt, in November, to dedicate financing sustainable development projects from the three climate commissions of the African Union (Congo Basin, Sahel Region and Island States).

Climate change is the biggest health threat facing humanity, and if we do not address it immediately and scale-up response and recovery, it will potentially undo the last fifty years of progress in development, global health, and poverty reduction, while severely jeopardising the realisation of Universal Health Coverage.
