Apr 02, 2021 | Eric Verploegen, Melissa Mangino, Kukom Edoh Ognakossan, Aly Ahamadou, Fatimata Cisse Diallo

MIT D-Lab, the World Vegetable Center, and Institut d'Economie Rurale (IER) have developed this guide in order to disseminate information about this simple, low-cost technology that uses the principle of evaporative cooling to provide improved storage for fruits and vegetables. The guide is available in French and English, and is the centerpiece of an ongoing training program in the Mopti region of Mali.


A heat and mass transport model of clay pot evaporative coolers for vegetable storage
Aug 28, 2020 | Danyal Rehman, Ethan McGarrigle, Leon Glicksman & Eric Verploegen

MIT D-Lab team developed a heat and mass transport model of clay pot coolers and validated the model using data previously collected in Rwanda and Mali. The model provides insights in how to optimize clay pot coolers for storing fruits and vegetables.


Assessment of the Use and Barriers of Evaporative Cooling Technologies by Small Holder Farmers in Kenya
Jan 20, 2020 | Benson Mania & Eric Verploegen

MIT D-Lab and the University of Nairobi published a research report on the awareness, use, and barriers to adoption of Evaporative Cooling Technologies in the Embu and Machakos Counties of Kenya. This findings presented in this report were based on interviews with farmers and include recommendations for approaches to increase awareness and adoption of Evaporative Cooling Technologies.


Evaporative Cooling for Improved Vegetable and Fruit Storage in Rwanda and Burkina Faso
May 29, 2019 | Eric Verploegen, MIT D-Lab; Rashmi Ekka & Gurbinda Gill, Agribusiness Associates

MIT D-Lab and Agribusiness Associates conducted a study of evaporative cooling devices in Rwanda and Burkina Faso, as part of a Feed the Future program run by UC Davis' Horticulture Innovation Lab. The results of this research provided insights into the impact of device design and weather conditional on performance, as well as providing recommendations for dissemination of evaporative cooling devices. 


Evaporative Cooling Technologies for Improved Vegetable Storage in Mali
Jun 01, 2018 | Eric Verploegen, Ousmane Sanogo & Takemore Chagomoka

MIT D-Lab and the World Vegetable Center published a research report evaluating technologies designed to improve the storage of vegetables using evaporative cooling. The methodologies used included interviews with users of the cooling and storage technologies, interviews with stakeholders along the vegetable supply chain, and sensors to monitor product performance parameters.
