One indigenous Ethiopian crop that exemplifies resilience is enset. Whereas most crops have relatively rigid planting and harvesting times, enset is flexible. As a perennial, enset grows larger each year until harvested, meaning you can leave it to continue growing if it is not needed. As well as being drought tolerant, rapidly clonally propagated and highly productive in a small area of land, processed enset is also highly storable.
However, enset is only grown in south western Ethiopia, where despite being the staple of 20 million people it is relatively easy to overlook globally. For this reason it has lacked international research attention, until recently.
