Food Insecurity: Hermetic Storage To The Rescue

Business Headlines


In its bid to improve methods of food storage after the harvest season, the United Nations World Food Programme (WFP) has made a profound discovery to deal with the food crisis -the hermetic storage technology.

The hermetic storage was made possible through a training of 300 farmers carried out by the WFP, in collaboration with the Agricultural Development Project (ADP) and the International Institute for Tropical Agriculture (IITA) in Yobe State, North East Nigeria.

Hermetic storage bags are airtight and waterproof, allowing farmers to store and save grains from infestations or destruction by insects, rodents, mold and moisture, thus preserving them for long periods of time.
A bag-opening ceremony on 10 July 2019 in Gashua, Yobe State, marked the highpoint of the training which aimed to reduce the losses suffered by farmers due to improper food storage.


According to figures by the Nigerian Incentive-Based Risk Sharing System for Agricultural Lending (NIRSAL), Nigeria loses some US$9 billion every year due to poor post-harvest management. More than 30 percent of staple food grains (maize, sorghum, millet) are lost due to poor storage, while 60 percent of vegetables perish.
After the training, each of the farmers received eight (8) specially made airtight 50 kg bags to store their grains for six months until the prices of grains rose in the market. The farmers stored cowpeas in the new airtight bags, while others stored theirs in the traditional ways.

“When the bags were opened in Gashua, the results were astonishing,” says Ms. Eden Guizaw, the WFP officer leading the Post-Harvest Loss Management Programme. “90 percent of the grains stored in the traditional way were lost, while 100 percent of those stored in the hermetic (airtight) bags were intact. It was amazing; indeed, beyond my imagination”.
One of the farmers, Hajia Taannabi, recorded a huge profit in her sales by using the hermetic storage bags to preserve her grains.

“I stored my grain with the hermetic bags, without losing any to infestation or rodents. I sold each mudu (measure for grains) for N400 and gained N300 on each mudu and was able to feed my family and pay my children’s school fees”, Hajia Taanabi said.


Building on the success of the pilot project, WFP will train more farmers nationwide in the use of the hermetic storage technology in the next phase of the programme – depending on the availability of funds. “Investments in this type of training and technology are critical to making progress in reducing food insecurity over time” says Sarah Longford, Acting Country Director for WFP Nigeria. WFP is also encouraging local businesses by supporting the production in Nigeria of the hermetic storage bags by some Nigerian private enterprises.

By promoting hermetic storage in Nigeria, WFP aims to contribute to post-harvest loss reduction and boost food security to achieve zero hunger.
