Indigenous crops with diverse genotypes facilitate cultivation of crops that are ideally suited to particular sites by small-scale farmers, thus staving off poverty and hunger in local communities while promoting responsible consumption and production. This paper evaluates grain yield and nutritional qualities of a range of genotypes in an African crop plant.
In China, efforts to use water more efficiently has led the increasing trend of crop irrigation water use to decelerate, a win for water sustainability. However, this study finds that since 2011, crop irrigation is increasingly using water resources considered "scarce" which is not sustainable.
Future sustainable food systems should more efficiently use natural resources and reduce food waste.

This content aligns with Goal 15: Life on Land and Goal 2: Zero Hunger by investigating how new genomic applications can leverage agricultural production and how the utilization of bioresources like cold-active enzymes and freeze-resistant proteins from glaciers may help develop more drought-resilient plants.
Edible macroalgae (i.e., ‘seaweeds’) are a nutritious and sustainable alternative to animal-based proteins.
This Article supports SDGs 3 and 13 by showing that plant-based beef alternatives could reduce the carbon footprint of the US food system, but highlights that reductions in other envirnmental dimensions are dependent on repurposing of resources.
This article contributes to the debate around the use of participatory approaches—in this case, giving a tool in the form of cameras to the most marginalized to revitalize traditional foods (mostly nonmarket and even noncultivated) as a response to food insecurity and possibly malnutrition.
Concerns over the impact of global meat production and consumption patterns are leading to increasing interest in alternative sources of protein.

This Viewpoint supports SDGs 2 and 15 by highlighting the importance of trees and forests to food systems, and exploring how the value of trees and forests in this regard can be enhanced to improve nutritional and environmental sustainability.
Meat induces large environmental impact while supplying important nutrients, and meat substitutes are increasingly adopted as direct replacers of meat products.
