Hanging vegetable gardens is an easy to implement practice allowing to grow healthy vegetables with no land and little inputs. Hence, it is very suitable for low-income families, slum dwellers, the landless, women who often have poor access to land and need to stay close to their homes, as well as for pastoralists who can thus move from place to place carrying their gardens with them. Hanging vegetable gardens can be made using waste plastic containers and clean water used in house chores (e.g. washing utensils), thus saving water. This technology help saving money to buy vegetables, while ensuring that families have easy access to nutritious vegetables, especially in times of the pandemic of COVID-19, which disrupted food distribution chains. For instance, a family of five in Kenya spends an average of Ksh 100 per day for vegetables. Cultivating their own hanging garden, they can save it, which translates to Ksh 36 000 in a year. This money can be used to educate a child in a boarding secondary school in Kenya and hence help to improve education and livelihoods. At the same time, healthy nutritious practices are promoted, helping to reduce levels of malnutrition in the communities. Use of safe waste plastic containers contributes also to reducing environmental pollution.
