“…Landscape‐level analyses matter not only for ecological outcomes but also for the formulation of best farming practices. For example, Stiles et al (2021) demonstrated that increased landscape diversity (measured as Shannon's diversity index with land use quantified in CropScape) in the South Dakota Prairie Coteau (a roughly 50,000‐km 2 plateau that rises from the flat prairies of western Minnesota and eastern South Dakota) resulted in higher pollinator diversity and higher yield in experimental plots of the new oil crop, Brassica carinata . Thus, landscape‐level management that increases pollinator diversity could increase farmers' net profitability by replacing costs associated with inputs such as tillage and neonicotinoid seed treatments.…”

“…Moreover, carinata has a moderate weed risk potential (US Department of Agriculture – Animal & Plant Health Inspection Service, 2014) with its low pod‐shattering and dormancy (Patanè & Tringali, 2011). It supports over 50 species of pollinators and 75 species of non‐pollinators, thereby providing biodiversity benefits (Stiles, 2019).…”

Brassica carinata or Ethiopian mustard, a non‐edible oilseed brassica, is a low carbon, purpose‐grown, and none‐to‐low indirect land‐use change bioenergy feedstock for the production of drop‐in sustainable aviation fuel, biodiesel, renewable diesel, and a suite of value‐added coproducts. Carinata oil converted to drop‐in fuel using an American Society for Testing and Materials approved Catalytic Hydrothermolysis process has been successfully tested in commercial and military aviation. Carinata meal, the residue after oil extraction, is a high‐protein feed supplement for livestock, poultry, and swine, and can also yield specialty products. The Southeast Partnership for Advanced Renewables from Carinata (SPARC) is a public–private partnership formed with a twofold mission: (1) Removing physical, environmental, social, and economic constraints that prevent regional intensification of carinata production as a low‐carbon feedstock for renewable fuel and coproducts and (2) demonstrating enhanced value across the entire value chain by mitigating risk to farmers and other stakeholders. The partnership's goal is to energize the US bioeconomy through sustainable agriculture and thus contribute to energy security and economic diversification. SPARC relies on a combination of cutting‐edge multidisciplinary research and active industry engagement to facilitate adoption of the crop. This involves informing stakeholders along the entire supply chain, from producers to end‐users, policymakers, influencers, and the public, about the opportunities and best practices related to carinata. This article provides context and background concerning carinata commercialization as a winter cash crop in the Southeast US for renewable fuels and bioproducts. The advances made to date in the areas of feedstock development, fuel and coproduct development, meal valorization, supply chain logistics, and stakeholder engagement are outlined.

“…Other insects, such as butterflies, flies and wasps also forage on Brassica flowers, but their contribution to boosting yields is negligible (Mishra et al 1988;Pudasaini et al 2015;Bajiya and Abrol 2017;Stanley et al 2017). The diversity of these insects within such crops may be raised if attributes such as restricted use of pesticides, wide availability of food and nesting resources and large-scale landscape (3 km) heterogeneity are present in these areas (Samnegård et al 2016;Landaverde-González et al 2017;Theodorou et al 2017;Stiles et al 2019).…”

Higher richness and abundance of flower-visiting insects close to natural vegetation provide contrasting effects on mustard yields

The conservation of pollinating insects in agriculture is a global concern since the diversity of such organisms may affect the productivity of pollination-dependent crops. In this study, we assessed (i) how distances from natural vegetation affect the diversity (guilds, richness, abundance) of flower-visiting insects within mustard crops in Nepal, (ii) how insect richness and abundance are related to mustard yields (weight of seeds) and (iii) the contribution of flower-visiting insects to mustard pollination by conducting pollinator exclusion experiments. To analyse these data, we carried out (i) hierarchical clustering followed by a Procrustes analysis as well as a generalized linear mixed model and (ii), (iii) linear mixed models. We found that the guild composition was not similar near and far from natural vegetation, indicating a tendency for Apis bees to displace in opposite directions relative to non-Apis bees. Nevertheless, while both richness and abundance were higher nearer natural vegetation, the former showed a stronger and more positive effect on mustard yields than the latter. Furthermore, we found that mustard flowers have a significant requirement for insect pollination since productivity increased by ~70% with insect visitation. Overall, our data suggest that the diversity of flower-visiting insects enlarges nearer to natural vegetation. However, the results indicate that species richness may be more relevant than abundance to mustard production. As such, we suggest that the maintenance of natural vegetation could be considered a strategy for ensuring the presence of multiple pollinator species within mustard fields to promote its long-term sustainability in Nepal.
