“…Regarding the need to supply protein-based foods to satisfy the world demand, it has been suggested that insects can have a role in partially replacing other more conventional sources of protein, especially those with the highest impact, which are bovines [8,[12][13][14]. In this way, insects and insect-based foods arise as meat alternatives that have a considerable lower environmental impact [15,16].…”

Are Consumers Aware of Sustainability Aspects Related to Edible Insects? Results from a Study Involving 14 Countries

In recent years, edible insects have been suggested as an alternative food that is more sustainable compared with other sources of animal protein. However, knowledge about the sustainability aspects associated with this source of food may play a role in convincing consumers to adopt insects as part of their diet. In this context, the present study investigated the level of knowledge about the sustainability of edible insects in a group of people originating from 14 countries, with some naturally entomophagous and others not. To measure the knowledge, 11 items were selected and the scores obtained were tested with statistical tools (t-test for independent samples, analysis of variance—ANOVA) to search for differences according to sociodemographic and socioeconomic characteristics, geographical origin, and consumption habits of edible insects. The obtained results showed that, in general, knowledge is moderate, with the values of the average scores for the 11 items investigated ranging from 0.23 ± 0.99 to 0.66 ± 1.02, on a scale ranging from –2 (=very low knowledge) to 2 (=very high knowledge). The highest scores were found for items relating to the lower use of animal feed and lower emission of greenhouse gases required for the production of insects compared with beef. When investigating the differences between groups of participants, significant differences were generally found, revealing a trend for higher knowledge among males and young adults, for participants residing in urban areas and in countries such as Spain, Mexico, and Poland, and for participants with higher education levels and higher incomes. When testing the influence of consumption variables on the level of knowledge, the results showed a higher knowledge for participants who had already consumed insects or are willing to consume them. Finally, it was observed that higher knowledge was found for participants whose motivation to consume insects related to curiosity, a wish to preserve the planet, the gastronomic characteristics of insects, and their nutritional value. In conclusion, these results clearly indicate a very marked influence of a number of variables on the knowledge about the sustainability of edible insects, and this may be helpful to delineate strategies to effectively raise knowledge and eventually increase the willingness to consider insects as a more sustainable alternative to partially replace other protein foods, even in countries where this is a not a traditional practice.

“…For animals to reach their maximum growth, knowing the amount of feed required to complement pasture intake is necessary. At high degrees of feeding precision, grazing undoubtedly contributes to lower GHG emissions, even without considering other advantages such as C sequestration (Reyes-Palomo et al, 2022). Nevertheless, if farmers miscalculate the amount of feed supplementation, particularly in pastures that do not provide feed in high amount and quality, then even relatively small variations in steer size (and therefore meat produced) can make it environmentally preferable to confine animals after weaning and feed them in controlled installations.…”

Greenhouse gas (GHG) emissions of beef production are extremely variable depending on the livestock production system (LPS) used, with lack of clarity on the influencing factors. Here, we assess those factors using a mass balance model with regional case study data, providing globally relevant insights. We show that the whole-system GHG emissions range for beef production is 15-124 kg CO2e 100 g protein-1 depending on LPS (confined, pasture-based or mixed), breed, age at slaughter, and adequacy and upstream impact of supplemental feed. If steers are adequately supplemented, then LPS that involve at least a stage of grazing for steers have the lowest emissions, regardless of supplemental feed impact. In case of suboptimal supplementation during grazing, confinement is optimal at intermediate to low feed impact. For high feed impact, slaughtering at weaning is optimal. Choosing the best LPS and slaughtering age reduces the range of emissions to 15-35 kg CO2e 100 g protein-1.

“…But what are the particular characteristics or mechanisms of these agroecological systems that enhance their resilience, i.e., reduce their vulnerability to climate change, compared with conventional systems? While there has been considerable research on the mitigation and adaptation potential of agroforestry systems (Hernández-Morcillo et al, 2018;Reyes-Palomo et al, 2022), the resilience potential of agroforestry, particularly in a European context, has not been well addressed, perhaps due to the complexity and diversity of these systems and the challenges of measuring or modelling resilience. An iterative expert knowledge-based Delphi study was undertaken to contribute to filling this knowledge gap and contribute to the development of an interactive map for policy makers and farmers.…”
