Underutilized crops are often indigenous ancient crop species which are still used at some level within the local, national or even international communities, but have the potential to contribute further to the mix of food sources than they currently do.

A question we often receive is “What plants will grow well in my area?”. This question is particularly relevant to underutilized crops, of which there are thousands. The answer depends on multiple factors. Plant species and varieties differ, for example, in their temperature and water requirements. Temperature is influenced by latitude and elevation among other factors. Rainfall varies with seasons, wind patterns, and proximity to mountains. You also need to consider other factors like daylength, changing climate, and what is already growing. 

You may wonder, “What resources are available that will help me decide what plants to try?” ECHO published a fairly detailed set of charts in the first chapter of Amaranth to Zai Holes (Comparison Charts of Tropical Crops below). They represent numerous categories of crops and are available online. In this collection are more extensive digital resources for identifying promising crops to work with. 

For any given crop of interest, there are additional resources that can help you gather more information on crop growing requirements and nutritional composition. ECOCROP is a rich source of descriptive (e.g., growth habit, lifespan) and climate (e.g., temperature and rainfall ranges) information on numerous crops. The World Vegetable Center has an interactive database that provides nutrient composition data for indigenous vegetables and other plants. You can also find nutritional data in plant fact sheets from Food Plants International.
