Mali’s horticulture sector plays a vital role in supporting the country’s human nutrition and health, income generation for farmers, and poverty alleviation. A lack of affordable and effective post-harvest vegetable storage solutions often leads to vegetable spoilage, loss of income, reduced access to nutritious foods, and significant amounts of time spent traveling to purchase vegetables, particularly in rural communities. In Mali – and many other developing regions – these challenges are found where farming is the predominant source of income and food for populations who lack access to affordable methods for cooling and storage of vegetables and leafy greens. The objective of this research study is to investigate the potential for non-electric evaporative cooling devices to address post-harvest vegetable storage challenges in rural Mali. The two classes of devices evaluated in this study are commonly known as “evaporative cooling chambers” (ECCs), which are generally used by horticulture cooperatives, and “clay pot coolers,” which are generally used in households. These devices rely on the evaporation of water to create a cooling effect, and their performance is significantly affected by the ambient temperature and humidity of the environment in which they operate. A combination of electronic sensors and structured user interviews was used in this study to gather information about users’ needs for improved post-harvest vegetable storage, current methods of post-harvest vegetable storage, and the performance of the evaporative cooling devices.
