Dear Colleagues,

As supply chain disruptions caused by the combination of the COVID-19 pandemic and climate destabilization caused food prices to soar, the entire global community was reminded of the fragility of our food system. The conventional agriculture-based global food production system is dependent on consistent environmental conditions such as sunlight, temperature and precipitation, all of which can be severely affected by both natural and anthropogenic factors. Climate destabilization is already increasing the risks of concurrent severe weather events [1] that reduce our food system performance [2], while also increasing the probability of simultaneous shocks that would create a multiple bread-basket failure [3]. 

To better prepare for potential future global food system shocks, we can develop resilient local food systems. Several studies have suggested that biomass could be converted to human-edible food in emergencies and provide a means to feed the global population when food stores are depleted [4,5]. To explore the potential of different means of converting waste biomass to human-edible resilient food for both emergencies, as well as a means of reducing food insecurity for the poor, this Special Issue explores a range of topics including:

• Agricultural crop residues as resilient foods.
• Algae as resilient foods.
• Alternative foods.
• Biomass.
• Biomass processing machines and equipment.
• Bioreactors.
• Biorefineries.
• Economics of resilient foods.
• Forestry residues as resilient foods.
• GIS analysis of biomass feedstocks.
• Leaf protein concentrate as resilient foods.
• Microbial biomass as resilient foods.
• Nutrition of biomass used as resilient foods.
• Resilient foods.
• Seaweed biomass as resilient foods.
• Single cell protein (SCP) as resilient foods.
• Toxicity testing of biomass.
• Wood processing residues as resilient foods.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Biomass is an international peer-reviewed open access quarterly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 1000 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
