Shibbir Ahmed, New York — The United Nations is warning of serious humanitarian and health risks in Gaza as winter approaches, with millions of Palestinians facing inadequate shelter, shortages of essential medical supplies and the growing threat of flooding. The UN World Health Organization (WHO) said on October 2 that repeated delays in bringing lifesaving medicines, prosthetics and other medical supplies into Gaza are putting people in urgent need of care at risk. WHO said almost 2 million people need shelter to protect them from cold weather and flooding, while humanitarian organizations continue to face difficulties bringing winterization and shelter supplies into the territory.
According to the UN Office for the Coordination of Humanitarian Affairs (OCHA), funding shortages and restrictions are severely limiting preparations for the rainy season. A recent OCHA assessment identified 451 displacement sites at high risk of flooding, hosting an estimated 464,402 people. WHO’s representative for the Occupied Palestinian Territory said that, as of October 2, no hospital in Gaza was fully functional, citing chronic shortages of medicines and medical supplies. WHO said large quantities of medical supplies have been waiting for clearance for a median of 74 days, creating significant delays in delivering healthcare assistance.
The UN has called for the unimpeded and predictable entry of humanitarian and health supplies at scale, as well as a system allowing aid to enter through multiple crossings. WHO officials also called for clearer procedures for the approval of humanitarian shipments to reduce delays and rejected consignments. The winter preparations come as Gaza continues to face severe infrastructure and humanitarian challenges. An OCHA report published in September said shortages of cancer medicines, chemotherapy and radiotherapy supplies, dialysis materials, insulin and other essential items were disrupting lifesaving health services.
The UN has also warned that damaged infrastructure and overcrowded displacement sites are increasing the risks associated with heavy rain and flooding. Earlier OCHA reporting said humanitarian efforts to prepare for winter were being constrained by funding shortages, restrictions on supplies entering Gaza and shortages of fuel, engine oil, spare parts and heavy machinery.
A UN report issued in September similarly called for urgent action to restore essential services in Gaza, including electricity, water, sanitation, waste management and healthcare. It described winterization as an urgent priority because shelter needs remain extensive while essential supplies and services remain severely constrained.
The UN’s latest warnings underscore the scale of the challenge facing humanitarian agencies as winter approaches, particularly for displaced families living in damaged buildings, tents and other inadequate shelters.
