Carolyn Sachs, Professor of Agricultural Economics and Rural Sociology, discusses gender aspects of agriculture that preserve biodiversity. One of her stories is from Swaziland where her team, while advising farmers on how to obtain a higher maize yield, observed that women weren't weeding the maize in a timely fashion. Several years later, the researchers discovered that two crops they had identified as "weeds" were known by the people to be healthful and provided an important source of pro-vitamin A for their family's diets.
