There is an interesting opinion piece on possible reasons and contributing factors to taro being an "orphan crop" (crops which are typically not traded internationally but plays an important role in food security, Falcon et al. 2017).
The article examines why this perception gap exists and offers some insights into how feedback loops can create and reinforce these perception gaps leading to taro being under-utilised, underfunded and under-researched.
