The scale of suffering in Yemen is staggering. Yemen is witnessing one of the world's largest humanitarian crisis with 21.2 million people – or 82% of the population – in need of emergency humanitarian assistance, including close to 10 million children.

Since March 2015, one million children have been internally displaced, eight million are now food insecure, seven million are without access to basic healthcare and nearly half of the school age population have not attended school during the past 10 months.

Save the Children has been working relentlessly to do whatever it takes to ensure no child in Yemen is left behind, reaching the most excluded children. We have provided emergency assistance to 600,000 people, including 350,000 children, since escalation in violence during March last year. Thanks to the tireless efforts of our national staff living within an extremely challenging context on the ground, we have successfully delivered sectoral response activities in child governance, child protection, education, healthcare, nutrition and WASH.

We must ensure however that Yemen's children – the country's future – are not paying the price for years to come by missing out on opportunities today in this already war ravaged country. 15-year-old Amjad* has been displaced with his family to Hajjah Governorate.

He told us, "The war is tracking us wherever we go. At the beginning of 2015 our camp was hit during an airstrike which killed my brother and my best friend. This forced us to move to a new camp where life is very difficult – there is no food, no water or school. We live in torn and old tents and there is no stability in my life, only fear all the time."

However, significant impediments to ours and the wider humanitarian community's ability to meet the population's growing needs remain. Insecurity, whether it be on the ground or from the air continues to undermine efforts. However, perhaps most troubling are signs already of donor fatigue, brought on in part by the multiple ongoing humanitarian crises both regionally and globally. Given the sheer scale of the humanitarian catastrophe unfolding in Yemen, this is not the time for donors to lose interest. Without their ongoing support, Yemen will quickly descend into a failed state with catastrophic consequences for its population.

This is why Save the Children is encouraging the international donor community to do more to fund the desperately under-resourced response, particularly in the child protection and education sectors in Yemen. Together we reach every last child, and ensure no child is denied the opportunity to survive and learn.
