This represents a critical design feature. Thus, ecological sanitation has the potential to reduce disease transmission, infections in people, and improve well-being, particularly of vulnerable groups. This allows better appetite and utilisation of food that is consumed, creating a healthier society. Of course, inappropriately designed ecological toilets or behaviours that extract the nutrients when still laden with pathogens could spread disease. Therefore, it is important to get it right from the start. When food is grown further away from where people live, it not only costs more, but perishables, which often contain valuable micronutrients, are less likely to reach consumers, particularly people with little income. Urban farming and home gardening, though, can result in better diets, improving macro- and micro-nutrient intakes as well as improved nutritional status of vulnerable groups, such as women, children, the elderly and disabled.
