Canada is one of the only member countries of the Organization for Economic Cooperation and Development (OECD) without a national school food program. Good nutrition impacts children’s health, wellbeing, and learning; and school food environments offer an important setting to promote health and other food system sustainability behaviours that can last a lifetime. We present an overview of national and international evidence, with a focus on promising practices that support the establishment of a national school food program in Canada. School food programs have been shown to benefit health and dietary behaviour and critical food literacy skills (learning, culture, and social norms) that support local agriculture and promote sustainable food systems. Finally, we make recommendations for key elements that should be included in a national school food program for Canada.

One of the main goals of Mankind is to ensure food system sustainability—including management of land, soil, water, and biodiversity. Microalgae accordingly appear as an innovative and scalable alternative source in view of the richness of their chemical profiles. In what concerns lipids in particular, microalgae can synthesize and accumulate significant amounts of fatty acids, a great fraction of which are polyunsaturated; this makes them excellent candidates within the framework of production and exploitation of lipids by various industrial and health sectors, either as bulk products or fine chemicals. Conventional lipid extraction methodologies require previous dehydration of microalgal biomass, which hampers economic feasibility due to the high energy demands thereof. Therefore, extraction of lipids directly from wet biomass would be a plus in this endeavor. Supporting processes and methodologies are still limited, and most approaches are empirical in nature—so a deeper mechanistic elucidation is a must, in order to facilitate rational optimization of the extraction processes. Besides circumventing the current high energy demands by dehydration, an ideal extraction method should be selective, sustainable, efficient, harmless, and feasible for upscale to industrial level. This review presents and discusses several pretreatments incurred in lipid extraction from wet microalga biomass, namely recent developments and integrated processes. Unfortunately, most such developments have been proven at bench-scale only—so demonstration in large facilities is still needed to confirm whether they can turn into competitive alternatives.

School Food Environment

The purpose of this study is to develop a novel framework that outlines the system required to implement scratch cooking in school kitchens. The data used in this study were 57 interviews with key stakeholders during the Return to Scratch Cooking Pilot that occurred in two New York City school kitchens in 2018–2019 and made significant modifications to many aspects of the existing school food system. The guiding framework for the data analysis was Meadows’s Intervention Level Framework. Intervention Level Framework describes analyzing systems by examining five layers: (1) paradigm shift, (2) goals, (3) system structure (4) feedback and delays, and (5) structural elements. It also provides a framework for describing a system by defining its elements, interconnections, and purpose. Data analysis revealed four elements of the school food system: ingredients and recipes, kitchen, cooking, and the community. The interconnections that played a role in each of these elements were policies, practice, people, and promotion. Together, these four elements and four interconnections comprise the Scratch Cooked School Food framework, which has the purpose of being a tool for researchers and practitioners to utilize when planning, implementing, and evaluating scratch cooking in the school food environment.

Improving the food system sustainability and security is becoming an urgent global challenge. In this regard, one of the most effective routes is the shift of the human diet toward healthier and more sustainable consumption, involving in particular the prevalence of plant-based raw food materials. Controlled hydrodynamic cavitation (HC) technologies could help considerably in this transition. HC techniques are gaining increased scientific interest, and are quickly spreading across a wide range of technical fields, recently showing surprising performances with biological raw materials related to the food, agricultural and forestry sectors and resources. HC processes enjoy recognized advantages in the acceleration of the processing steps of plant-based food, the extraction of valuable bioactive compounds, the reduction and the valorization of waste streams, as well as the superior efficiency in resource use, energy consumption, process yield, and exergy balance than competing processes. Thus, HC is very promising candidate to help addressing the water-energy-food nexus, and, ultimately, sustainability. Findings obtained from direct experimental trials and recent literature concerning the applications of HC to food processing, provide a strong basis for novel investigation aimed at standardization, starting from the identification of the most suitable devices and the optimal processing parameters, eventually oriented to further spreading of HC applications.

The rise of global attention toward sustainability and sustainable development (SD) has provided increased incentives for research development and investment in these areas. Food systems are at the center of human needs and global population growth sustainability concerns. These drives and the need to provide quantified support for related investment projects led to the proliferation of sustainability metrics and frameworks. While questions about sustainability definition and measurement still abound, SD policy design and control increasingly need adequate quantified support instruments. This paper aims to address this need, contributing to a more consistent and integrated application of food system sustainability metrics and quantified management of the implemented solutions. After presenting the relationships between sustainability, resilience, and robustness and summarizing food system sustainability quantification developments so far, we expose complexity sciences’ potential contributions toward SD quantified evaluation, addressing prediction, intangibles, and uncertainty issues. Finding a paramount need to make sense and bring existing sustainability metrics in context for operational use, we conclude that the articulated application of multiple and independent modeling approaches at the micro, meso, and macro levels can better help the development of food SD policies and implemented solution quantified management, with due regard to confidence levels of the results obtained.

Sustainable Food System

Policy plays significant role in defining the food system of any country, and a sustainable food system is necessary for food security. This chapter maps out the causal interactions between food systems, food security and policy, and the challenges in transition to a sustainable food system while respecting the rights of all people to have access to adequate food in Nigeria. Explicit, rigorous, and transparent literature search was undertaken and many articles were assessed and reviewed. Although the results established a mutual relationship between food system and food security, existing literature have widely failed to take interactions between food systems, food security and policy into account. While food production is used as an entry point to improving food system sustainability, the quest for food security are undermining transition towards sustainable food systems. It was found that without right policies in place, it may be difficult to have food systems that are sustainable and ensure food security. This chapter provides a useful contribution to policy, and research on transitions towards sustainable food system. Any policy intervention to address one part of the food systems will impact on other parts and will determine whether a country is food secure or not. Enabling policy environment is therefore essential in ensuring a sustainable food system and for the attainment of food security.
