Neglected and underutilized crop
The demand that certain crops have a given set of properties changes over time.  To be able to cope with climate change, it may be necessary to have crops which are better adapted to the climate in which they are grown. Many neglected crops have been reconsidered, because they have useful properties. Examples are oil palm, soybean, and  kiwifruit. They used to be neglected, and are now grown worldwide. That way, many species can contribute to food security, or a more varied diet. They may also be better for health.
