A third of the global food wastage happens during post-harvest according to international reports.
According to figures by the Nigerian Incentive-Based Risk Sharing System for Agricultural Lending (NIRSAL), Nigeria loses about $9 billion yearly due to poor post-harvest management. More than 30 percent of staple food grains, such as maize, sorghum, millet, are lost due to poor storage, while 60 percent of vegetables perish.
For this reason, there has been a worldwide effort to reduce post-harvest losses against the backdrop of an increasing world population.
One goal of the World Food Programme (WFP) is to support a post-harvest system in Nigeria that ensures farmers take delivery of crops from the farm at harvest with minimum loss, maximum efficiency and returns for all involved.
For instance, WFP has played a key role in minimising post-harvest loss of cowpea and increasing supply. A training carried out in Yobe State has improved methods of food storage after the harvest season.
WFP, in collaboration with the Agricultural Development Project (ADP) and the International Institute for Tropical Agriculture (IITA) trained 300 farmers on post-harvest best practices – using hermetic storage technology.
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.
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,” Ms. Eden Guizaw, the WFP officer leading the Post-Harvest Loss Management Programme said. “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,” Acting Country Director for WFP Nigeria, Sarah Longford said. WFP is also encouraging local businesses by supporting the production 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.
