Zero Emission Fridge for Rural Africa (ZEFRA)
Zero Emission Fridge for Rural Africa (ZEFRA) also known as Silo Tehetere is a seed storage silo built with local materials. It supports subsistence farmers in Mozambique to sustain food security through reduction of post-harvest losses. Furthermore, the silo helps the farmer families to adapt to climate change that is extending the drought-caused October-to-January ‘hunger period.’
Mozambique primarily and other countries in Africa.

Low-income segment, subsistence farmers, farmer cooperatives/ community seedbanks or individual farmers in the northern provinces of Mozambique, who typically sells off grain and then do not have enough surplus left over for hungry season. ^Interview ^with ^representative
Individually built by farmers with support/ instruction from HELVETAS Interview with representative
The ZEFRA construction relies on existing local knowledge/expertise. Users are responsible for procurement of necessary construction materials. Helvetas Mozambique is available to provide support.
More than 800 were built and used in 2010 in Mozambique, each of them benefiting an average of 10 families.
The basic design of the ZEFRA is a weaved bamboo structure covered with clay on both sides. The clay carcass of the silo seals the seeds in an almost hermetic chamber and improves the effect of the organic, herbal repellents, which is used to inhibit insects such as the granary weevil. It stands on a base that incorporates vermin traps to protect the grain from rats and mice. The ZEFRA is installed under a simple shelter to maintain cool, dry and constant conditions.
Together with the local NGO AMA (associação do meio ambiente) Helvetas Mozambique provides training courses for post-harvest techniques including the construction of silos Tethere, climate mitigation, post-harvest, seed-bank management, leadership and conflict management. Interview with representative
ZEFRA construction materials include bamboo and clay and can be replaced based on local availability.
Reduction of post-harvest losses and the establishment of seed banks that store sufficient seed reserves.
