Edible insects: Maybe environmentally friendly, maybe healthy, maybe tasty—But are we ready to farm them?

Abstract

For some time, environmental researchers and activists have been trying to convince the world that there is an urgent need to change the dietary habits of the modern human population. Their reasoning is based on several issues, with two main pillars supporting the whole concept. One involves mitigating global hunger, and the other addresses the impact that today's agricultural production has on the environment, particularly due to extensive and intensive agricultural practices, especially in developing countries and regions that help feed their populations. Perhaps the most promising proposal—and, as bibliometric analysis shows, more and more popular in the scientific community—is to replace animal protein with insect protein. It would allow for shifting agricultural production from animal-based to insect-based. In order to address this concept, the research community has been deeply involved in studying edible insects over the last decade. In doing so, researchers have examined nutritional value, sustainable production and environmental impact, consumer acceptance, and the challenges and opportunities from various perspectives. One might think that with such deep knowledge, the agricultural industry is well-equipped to initiate this shift. In this article, we argue that this statement is far from true. It appears that the scientific literature on edible insects fails to address what is likely the most important aspect for producers: farming techniques and practices, along with related topics such as feeding, protection from diseases, pathogens, and pests, rearing conditions, breeding, and many other factors. The critical need to improve the sustainability of global agricultural production and reduce its environmental impact calls for rapid changes, so the agricultural research community should stop waiting for others to decide whether edible insects are the way to go. Instead of waiting, they should focus on addressing the most critical aspects of insect farming. The industry is, in fact, ahead of science, as insect farms are spreading across the world. However, for them to succeed, strong support from agricultural science is urgently needed.
