Technological advances, particularly in analytical instrumentation, bioinformatics, and sample preparation, enabled development of objective, fast, multiplexed, and deep molecular screenings also for complex samples, such as raw materials and food products. The comprehensive and precise molecular profiles and fingerprints as well as unique molecular markers are determined, both qualitatively and quantitatively, for a broad range of food products with specific sensory properties. Novel analytical platforms and instruments are implemented, methods optimized, and protocols developed for a large number of applications, for instance in food microbiology, toxicology, authentication, food quality control. Modern food analysis technologies enable novel insight and provide good foundations for precise determination of geographical origin, genetically modified food, and differentiation between organic and conventional food. The study of effects of food and nutrition on human health and well-being was facilitated. All enumerated may assist in providing enough safe and quality food to the growing human population, and is possible due to application of foodomics technologies, particularly, genomics, transcriptomics, metabolomics, and proteomics, in food analysis. This review is a comprehensive summary on developments in the fields of food analysis and foodomics from 2014 to 2020 with the emphasis on mass spectrometry (MS)-based analytical platforms and their usage in analysis of food contaminants, proteins, and small molecules. Other foodomics techniques are mentioned in brief. A separate paragraph is dedicated to MS-based imaging technologies in food analysis and foodomics imaging methods, a new emerging technology.","PeriodicalId":39273,"journal":{"name":"CAB Reviews: Perspectives in Agriculture, Veterinary Science, Nutrition and Natural Resources","volume":"34 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-11-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78122928","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}

As an alternative food network (AFN) and a form of civic agriculture, it is considered a more sustainable way of food production and consumption compared to the conventional food system. The number of CSA initiatives has been increasing in the last few decades worldwide parallel to growing scholarly debates about its usefulness, viability and potential. This article contributes to the review of the following: The impacts of CSA on individuals and communities, including motives for involvement and benefits received; the impacts of CSA on food systems, particularly on sustainability; and the barriers and opportunities for CSA growth. We conclude that CSA addresses the needs for sustainable and ecologically sound food and contributes to community building by reconnecting urban and rural places and people with their food. It is also an active position against the unsustainable dominant food systems and shows a different way of caring for the planet and the people. However, in order to grow, CSA needs to overcome certain barriers, namely financial difficulties, unrealistic member expectations and the need for social justice by providing livelihoods for the farmers and becoming more inclusive in terms of race, income and gender. The COVID-19 crisis presented an opportunity for CSA to become more effective as the CSA initiatives demonstrated resilience during lockdowns and the demand for their products increased.","PeriodicalId":39273,"journal":{"name":"CAB Reviews: Perspectives in Agriculture, Veterinary Science, Nutrition and Natural Resources","volume":"11 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79186541","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}

Milk production follows a common pattern in several mammalian species known as a lactation curve. A typical lactation curve starts at day four after calving, reaching peak yield in early lactation, followed by a daily decrease in milk yield (persistency) until the lactating female is artificially dried off, or the lactation comes to a natural end. Mathematical models have been applied to lactation curves to provide information in relation to lactation curve parameters, providing valuable information for herd management and breeding decisions. Therefore, the aim of this study was to review the most used mathematical models for the prediction of dairy production curves. The importance of modelling lactation curves is to predict the yield for each day with the minimum possible error, to be able to elucidate the underlying pattern of milk production in the presence of local variation associated with the effect of the environment. The usefulness of any model of adjustment to the lactation curve depends on its capacity to mimic the biological process of developing milk production and to adjust the factors that affect it. Furthermore, these models can only be used to adjust productive records adequately, or to provide a biological understanding of the lactation process.","PeriodicalId":39273,"journal":{"name":"CAB Reviews: Perspectives in Agriculture, Veterinary Science, Nutrition and Natural Resources","volume":"25 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73493086","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}

Emerging studies in Africa have shifted the attention to indigenous knowledge (IK) to support the development of effective climate change adaptation strategies. This study adopted a systematic literature review methodology to analyse the following: (i) characterization of IK, (ii) potential of IK for knowledge co-production, (iii) IK for climate change causes and impact identification, (iv) IK for formulating and implementing climate change interventions, and (v) documentation and conservation of IK as a resource for climate change adaptation. Results show that there is no consensus on the definition of IK. However, certain identical elements in the available definitions are relevant for contextualization. IK has been useful in the formulation of different climate change adaptation strategies: management practices, early warning, and risk and disaster management. IK has the potential for knowledge co-production relevant for developing robust adaptation measures. Weather and climate services remain a critical area where IK and scientific knowledge (SK) are integrated to enhance forecast reliability and acceptability for local communities. IK is disappearing because of modernization and rural-urban migration, changing landscape and shifting religious beliefs. We suggest the need for more research into the complexity of the IK, proper documentation and storage of IK, and developing effective approaches to integrate IK with SK such that it is well received among researchers and policymakers. While doing this, it is important to maintain the unique features that distinguish IK from other forms of knowledge.","PeriodicalId":39273,"journal":{"name":"CAB Reviews: Perspectives in Agriculture, Veterinary Science, Nutrition and Natural Resources","volume":"88 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80920629","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}

However, most red fruits available to consumers typically contain only small amounts of anthocyanins, mainly limited to the epidermis of plant organs. Therefore, we reviewed the current literature on the biosynthesis of anthocyanins in berries, including the structural and regulatory genes involved in the differential pigmentation patterns of plant structures, as well as management and cultural treatments. Also, the genetic regulation of flavonoid biosynthesis in different red fruits is explored to observe and create strategies to increase biosynthesis and anthocyanin accumulation. It is concluded that the regulation, transport and accumulation of flavonoids varies markedly between species, and is influenced by abiotic and biotic factors.","PeriodicalId":39273,"journal":{"name":"CAB Reviews: Perspectives in Agriculture, Veterinary Science, Nutrition and Natural Resources","volume":"151 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77786877","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}

Microalgae species with high protein concentration and adequate amino acid (AA) composition can be used to substitute conventional protein feeds, whereas species with high carbohydrate or lipid concentration can be used to supply energy. Microalgal polyunsaturated acids and short-chain fatty acids have potential to improve the nutritive value of ruminant milk and meat for human consumption and mitigate enteric methane emissions. Microalgae composition is very plastid in comparison to conventional ruminant feeds and it can be influenced relatively easily by environmental conditions, such as nutrient supply. Microalgae also contain many compounds, especially carbohydrates and cell coverings, which are not usually found in ruminant feeds. Standard feed evaluation methods involving the use of crucibles or nylon bags (detergent fibre method, in vitro digestibility and in vivo rumen incubation) suit poorly to the analysis of microalgae with microscopic particle size. This paper attempts to give a general overview of the nutritive value (protein, lipids and carbohydrates) of microalgae for ruminant feeding applications and the possibilities to tailor microalgae composition for a certain ruminant feeding objectives. In addition, the key knowledge gaps related to the nutritive value of microalgae for ruminant nutrition are identified.","PeriodicalId":39273,"journal":{"name":"CAB Reviews: Perspectives in Agriculture, Veterinary Science, Nutrition and Natural Resources","volume":"30 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87502346","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}

This is happening via several pathways, among which plant pests are a leading cause. To contribute to more evidence-based decisions and policies, a team from the Food and Agriculture Organization of the United Nations (FAO) carried out a comprehensive literature review on rice (Oryza sativa) and cassava (Manihot esculenta), the major pests and diseases affecting them, and the impact of climate change on the latter. Rice is the major staple crop for about half the world's population. Most studies conclude that pest pressure will increase on rice under future climate change. There are a lot of pests of rice, among which brown planthopper (Nilaparvata lugens) is the most important pest. Leaf blast disease caused by fungus Magnaporthe grisea is the most significant disease, with losses of up to USD 66 billion dollars per year that are equivalent to the amount needed to feed 60 million people. Cassava is the major staple crop and crucial for food security in many countries of the world. A study has shown that cassava production will vary from -3.5% to +17.5% within Africa under 2030 climate projections. Unfortunately, as other crops, cassava will be vulnerable to pests and diseases. Over a third of attainable cassava yield is lost every year to pests and disease alone.","PeriodicalId":39273,"journal":{"name":"CAB Reviews: Perspectives in Agriculture, Veterinary Science, Nutrition and Natural Resources","volume":"226 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88353187","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}
