In Nepal's plains, traditional bins help keep food safe from heat, floods

Key Points

The aim is to assess how traditional earthen storage bins help in food preservation among Indigenous communities in Nepal.
Field observations in Nepal's plains focusing on the Tharu and Yadav communities.
Analysis of materials used in making traditional bins and their influence on food storage.
Evaluation of the effectiveness of these bins against climate challenges like heat and flooding.
Traditional earthen bins effectively regulate temperature and moisture, providing safe storage for grains.
These bins help maintain local seed diversity and adapt to climate challenges without modern technology.
Despite their benefits, they require careful monitoring and adaptation to remain effective against environmental threats.

Abstract

In Nepal's southern plains, Indigenous communities such as the Tharu and Yadav use traditional earthen storage bins (dehari) to safely store grains and seeds, relying on knowledge passed down through generations. Made from locally available materials such as clay, husk and dung, the bins naturally regulate temperature and moisture, helping protect crops from extreme heat, pests and seasonal flooding without electricity. Experts say these traditional storage systems are climate-adaptive, environmentally friendly and crucial for preserving local seed diversity and sustaining smallholder farming systems. While durable and effective, dehari have limitations such as vulnerability to moisture, pests and floods requiring careful placement, regular monitoring and adaptation to changing climate conditions.
