There are about 500 million smallholder farmers around the world. They produce much of the world’s food using only a small fraction of agricultural land and resources. Ironically, this is the group that suffers disproportionately from hunger, poverty and impacts of climate change. Improving the way small farms are designed and managed so that they’re more productive and profitable is an important mechanism for dealing with these issues in a systemic way. Emma Naluyima, a farmer in Uganda, has demonstrated that it is possible to produce abundant and diverse food on a one-acre farm while reducing inputs and increasing profits. She does this through the circular management of resources, a focus on healthy soils, and the application of appropriate technology.
