{"title":"Millet production, challenges, and opportunities in the Asia-pacific region: a comprehensive review","authors":"M. Harish, A. Bhuker, B. S. Chauhan","doi":"10.3389/fsufs.2024.1386469","DOIUrl":"https://doi.org/10.3389/fsufs.2024.1386469","url":null,"abstract":"Global warming, water scarcity, population growth, rising food prices, urbanization, and other socio-economic factors pose significant threats to agriculture and food security in the 21st century. This situation is particularly grave for low-income individuals in the Asia-Pacific region. To tackle this challenge and eradicate hunger and poverty, it is imperative for scientists to explore alternative food sources, covering all stages from production through processing to consumption. Cereal grains serve as a crucial food source and hold substantial importance in human diets. Therefore, revamping the food system becomes crucial to achieve food and nutritional security. A pragmatic approach toward reaching this goal involves ensuring universal access to affordable, wholesome, and nourishing food through the utilization of millets—nutrient-dense grains (often referred to as Nutri-cereals) that offer a rich array of vital macronutrients, micronutrients, carbohydrates, protein, dietary fiber, lipids, and phytochemicals. Leveraging these grains holds the potential to significantly alleviate the challenges of food insecurity and malnutrition. Millet, a drought-resistant grain, constitutes a primary source of carbohydrates and proteins for populations residing in semi-arid regions of Africa and Asia. Given its crucial contribution to national food security and potential health advantages, there is a growing focus among food scientists. Additionally, the United Nations designated 2023 as the International Year of Millet, underscoring its importance. This article delves into various methods of production and processing, highlighting opportunities to enhance the production and nutritional qualities of millet. We attribute millets to inadequate rainfall distribution, poor crop management high prices of farm inputs such as fertilizer and pesticides and low adoption of improved varieties by the farmers. It also outlines the constraints, challenges, and future prospects associated with promoting millet as a viable food source for the burgeoning population. Despite the promise that millets hold, they have not received adequate research attention. Therefore, increased research efforts on integrating genomics in genome-wide marker-trait association are imperative, encompassing germplasm collection, protection, evaluation, consumption patterns, development of high-yielding cultivars, processing techniques, and policy interventions. Such initiatives are necessary to bolster the cultivation of millets and harness their potential to address the escalating global food challenge.","PeriodicalId":504481,"journal":{"name":"Frontiers in Sustainable Food Systems","volume":"30 4","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140378230","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In addition, the plasma treatment confers antimicrobial properties, which we hypothesize to be transferable to methanogenic archaea and hence prevent methane formation during manure storage – a major contributor to global anthropogenic greenhouse gas emissions. In this work we compared the methane formation from cow manure to the methane formation in nitrogen enriched cow manure, kept in two outdoor storage tanks for 70–80 summer days over three consecutive years. In all instances, the methane formation was eliminated completely. To investigate the cause of inhibition, a controlled incubation experiment was conducted to show that neither the acidification nor the addition of nitrate or nitrite, alone or in combination, could explain the inhibition of methanogenesis and denitrification that occurred in plasma treated cow manure at moderate pH.","PeriodicalId":504481,"journal":{"name":"Frontiers in Sustainable Food Systems","volume":"113 22","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140380146","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

China strives to build a complementary reserve system between government and enterprises, and how to improve the efficiency of food reserves is a matter of great concern to the government and society. Based on the analysis of the connotation of food reserve efficiency, this paper constructs the revenue function and the cost function of food reserve in an emergency and uses the cost–benefit method to explore the best ratio of government reserve, corporate social responsibility reserve, and commercial inventory when maximizing the efficiency of food reserve. This ratio is closely related to the total food reserve, the scale of supply interruption, the reserve cost of food stored by enterprises, and the government’s subsidy cost for the social responsibility reserve. The unit subsidy cost of government to social responsibility reserve is inversely proportional to the proportion of corporate social responsibility reserve to corporate reserve. Doing a good job in the social responsibility management of food enterprises is an effective way to improve the efficiency of food reserves. To expand the scale of social responsibility reserves and realize “storing food in enterprises,” the subsidies given by the government for corporate social responsibility reserves should not be too high. Taking food social responsibility reserve as an important part of corporate social responsibility, it’s the key to promoting enterprises to actively undertake food social responsibility reserves. The conclusion of this paper provides a theoretical basis and decision-making reference for how to improve the efficiency of food reserves.","PeriodicalId":504481,"journal":{"name":"Frontiers in Sustainable Food Systems","volume":"37 8","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140077217","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"Territory in urban food policies: the case of Spain","authors":"Henar Pascual, Juan Carlos Guerra","doi":"10.3389/fsufs.2024.1359515","DOIUrl":"https://doi.org/10.3389/fsufs.2024.1359515","url":null,"abstract":"Over the last few decades, cities have taken on an active role in the formulation of food policies in line with the transition toward local, sustainable food systems. These policies have been materialized through the formulation of systemic, holistic urban food strategies. By setting up spatial, relational and organizational proximity circuits, they aim to reconnect the places involved in the production and consumption of food within the territory. The objective is to do so by interaction between the networks of actors on the different geographical scales. This article analyzes the food policies of six Spanish cities that signed the Milan Urban Food Policy Pact. Barcelona, Madrid, Valencia, Vitoria, Valladolid and Zaragoza have fulfilled their promise by formulating food strategies that set out their commitment to the construction of new, urban food systems that reconsider, from a territorial perspective, the relationship between the city and food. Using a conceptual framework that spans two well-known theoretical systems (the local territorial systems (LoTS) and the sustainable food networks (SFN)); a systematic review of the documents generated in the formulation of the urban food policies is carried out. The territorial capital linked to food is examined; the systems of actors that make up the food strategies are identified; the models of governance that the said strategies deploy and their capacity for self-organization are typified; and the potential of the public agendas for encouraging the construction of localized alternatives and the territorial sustainability of the urban food systems are evaluated. The results suggest that the Spanish urban food strategies, although conceptually inspired by the principles of the Milan Pact, are still far from possessing similarly transformative capacities. Such capacities are directly linked to the characteristics of the place: the existence of relational goods connected to food, the attributes of the territorial food capital, the density of the social capital, and the culture of the territorial planning. Beyond the generic references to the commitment to food, it is the context that determines its personality and reach, the solidity of the food governance, and the political sustainability of the processes that one wishes to set up.","PeriodicalId":504481,"journal":{"name":"Frontiers in Sustainable Food Systems","volume":"38 26","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140077131","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Nutritious food is essential for human health and helps oneself live up to our best potential as productive members of society. In spite of this, 3 billion people are estimated to have limited access to nutrient-rich food, and there are 768 million undernourished people in the globe today. There are still concerns with food systems and food security, despite the fast economic transformation of low-and middle-income nations in Maritime Southeast Asia and Oceania over the past 10 years. These issues include dwindling agricultural land, deforestation, ineffective food supply networks, environmental degradation, changing and unhealthy diets, non-communicable diseases, disappearing cultural legacy, and ineffective policies. These problems are exacerbated by climate change, natural hazards, and pandemic shocks. This review explores the perspectives of food systems that relates to all the elements and activities in transforming agri-food industry. In this paper, we discuss the challenges and solutions to transforming food systems in this region to achieve a sustainable and healthy diet for all, with the perspective of bringing the region closer toward the UN sustainable development goals. This paper is an outcome of the deliberations that took place during the Food Security in Small Islands and Developing States workshop in 2020. It also includes insights from subsequent expert group sessions that focused on the following topics: Agriculture and Food Systems; Nutrition, Health, and Culture; Innovations and Digitalization in Food Systems; as well as Policies Coordination and Future Shocks.","PeriodicalId":504481,"journal":{"name":"Frontiers in Sustainable Food Systems","volume":"137 35","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140078472","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

They have an important number of bioactive compounds and add color, texture, and flavor to dishes and salads. Given their benefits, small size, and high market prices, they can grow in indoor systems, where light is determinant. This study aimed to evaluate the effect of different light intensities on agronomic characteristics, color, chlorophylls and carotenoids content, and antioxidant activity represented by total phenolic content (TPC), eliminate, and antioxidant capacity (AC) in four Brassicaceae species in two colors (green and red). The experiment was conducted in a controlled light-emitting diode (LED) environment growth chamber (day/night temperatures of 25/20 ± 1.2°C, 16 h photoperiod, and 79 ± 2% relative humidity). Three light intensities were used for microgreen growth with the same LED light spectrum: low (120 ± 5.1 μmol m−2 s−1), medium (160 ± 3.6 μmol m−2 s−1), and high (210 ± 5.9 μmol m−2 s−1). Eight g of the seeds of green and red cultivars of cabbage, kale, mizuna, and mustard were sown in a plastic tray (64 cm x 35 cm x 6 cm) with a mixture of peat and perlite (1:2 = v: v). Overall, the high intensity increased dry matter percentage and dry weight, except in green and red kale and green cabbage cultivars. In contrast, low intensity promoted a larger hypocotyl in all species than with high intensity; moreover, it enhanced the cotyledon area in green and red mizuna. Cabbage, kale, and mustard green cultivars were greener under medium intensity, whereas the low intensity enhanced the purple color of mizuna. In addition, chlorophyll a and b increased under low intensity in most species except the red kale and mustard cultivars. The high intensity raises the antioxidant activity, promoting a higher TPC and AC. The findings revealed that the light intensity generated variations in agronomic characteristics, color, chlorophyll content, and antioxidant activity of Brassicaceae microgreens, and the changes were based on the specific species and cultivars.","PeriodicalId":504481,"journal":{"name":"Frontiers in Sustainable Food Systems","volume":"77 11","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140080312","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Research has shown that the multiple benefits of an edible campus, which may also be referred to as a school garden or farm catering to various educational levels, can help alleviate the aforementioned problems. However, there is limited research on how to promote the benefits of an edible campus through design. Therefore, taking the South Campus of Hebei University of Technology in China as an example, this paper aims to explore the correlation between design and benefits of an edible campus. The design factors and benefit factors related to an edible campus are extracted through literature search. The design preferences and benefit predictions are obtained through 261 questionnaire surveys and interviews with 30 participants. During the statistical analysis phase, principal component analysis and multiple regression analysis are applied to analyze the correlation between design factors and benefit factors. The results indicate: (1) The design factors of an edible campus can be categorized into seven categories: spatial location, spatial carrier, size, space function, facility configuration, planting and crop varieties, and technology application. (2) The benefits of an edible campus include environmental education, physical and mental health, social interaction, ecological protection, and economic output. (3) There are significant differences in design factors that positively or negatively correlate with different benefits. Among them, the strongest positive correlation exists between planting function and the five benefits, followed by central landscape and container planting. Furthermore, the causes behind the correlation between design factors and benefit factors are analyzed, and design strategies for an edible campus under different benefit orientations are proposed. The findings of this study can contribute to the sustainable development of university campuses in China.","PeriodicalId":504481,"journal":{"name":"Frontiers in Sustainable Food Systems","volume":"118 6","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140088199","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The agricultural sector is key for a secure supply of food but relies up to 50% on mineral fertilisers to meet crop nutrient demands. As mineral fertilisers production is energy intensive, causing close to 2% of global greenhouse gas (GHG) emissions, this poses greater challenge to meet net zero targets. Other challenges include extreme weather patterns, GHG during fertiliser applications and diffuse pollution, declining soil health, pest, disease, and loss of soil biodiversity. As mineral fertilisers’ price increases and the state of soil health decreases, innovative solutions are needed to meet crop nutrient demands while ensuring that sufficient organic matter is conserved in the soil. One solution to achieve net zero in agriculture can be in the form of organo-mineral fertilisers (OMF). OMFs are a new concept that take organic feedstock (such as biosolids, livestock manure, crop residues, food waste) and combines them with reduced amounts of mineral fertilisers resulting in a balanced fertiliser product. This Perspective piece discusses a Strength-Weakness-Opportunities-Threats (SWOT) analysis on OMF and summarizes how OMF applications can play a role to improve food security. This is further linked with short, medium and long terms policy interventions that can be deployed to achieve a more sustainable approach by balancing between protecting the wider environment and meeting food security.","PeriodicalId":504481,"journal":{"name":"Frontiers in Sustainable Food Systems","volume":" 637","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140092444","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
