The goal was to develop a locally appropriate technology that reduces labor intensity, improves oil yield, and eliminates reliance on firewood. The press, constructed primarily from scrap and locally available materials such as recycled metal for the frame was fabricated at a total cost of approximately USD 90. It eliminates the need for electricity, reduces processing time by 98.7% (from five hours to four minutes per batch), and improves oil yield (8.5-9.5% compared to the traditional 5-7%). Field tests conducted in Ondobe demonstrated additional benefits: zero firewood use (when seeds are not roasted), significantly reduced labor burdens for women, and enhanced oil clarity. Further testing with different press chamber sizes showed improved oil recovery efficiency with smaller diameters, supporting the potential for community-level scaling of the technology. By prioritizing local knowledge, community participation, and sustainable material use, the innovation aligns with Namibia’s broader goals for climate resilience and gender equity, offering a scalable, culturally grounded model for processing indigenous crops."]},{"key":"dc:format","label":"Dc Format","values":["application/pdf"]},{"key":"dc:title","label":"Title","values":["Contextual engineering for sustainable Kalahari melon oil extraction in rural Namibia"]}]}],"canonical_facts":{"dc:contributor":["Witmer, Ann-Perry"],"dc:creator":["Kandume, Jason N."],"dc:date":["2025-07-22","2025-08"],"dc:description":["Submission original under an indefinite embargo labeled 'Open Access'.
