Soil organic carbon in sandy soils: A review

Jenifer L. Yost, Alfred E. Hartemink, in Advances in Agronomy, 2019

2.5 SOC studies in sandy soils

Over 32,000 papers have been published on sandy soils between 1914 and 2017 (Scopus data; Fig. 3). Approximately 37% of the papers were from the agricultural and biological sciences, 21% from environmental science, and 15% were from earth and planetary sciences (Scopus data). In the past 10 years, some 1000 to 1800 papers are annually published on sandy soils. Of these, about 25–70 papers each year focus on SOC in sandy soils, and the number of papers on SOC and sandy soils is doubling every 10 years.

Data extracted from Scopus.

We extracted papers since the early 1990s, and grouped them by continent, climate zone, land cover, soil order, and focus of the research. The papers included soils with a minimum sand content of 600gkg−1. Most research on sandy soils has been conducted in Europe and in Africa. Fewer studies have been conducted in Asia, South and North America, and Australia. A large portion of the papers were based on research conducted on Entisols, and Spodosols were the second most studied soil order. Most papers were based on research conducted on sandy soils under agriculture or forest.

An Evolutionary Perspective on Industrial and Sustainable Agriculture

John Gowdy, Philippe Baveye, in Agroecosystem Diversity, 2019

Alternative Paths

Agroecology can be considered the overarching scientific framework for developing specific alternatives to industrial agriculture. According to Altieri and Nicholls (2015), “Agroecology is a science that draws on social, biological and agricultural sciences and integrates these with traditional knowledge and farmers' knowledge. … At the heart of the agroecology strategy is the idea that an agricultural system should mimic the functioning of local ecosystems, thus exhibiting tight nutrient cycling, complex structure and enhanced biodiversity.”

Agroecology applies ecologic principles to food production systems. It does not reject all technology but attempts to minimizes or eliminate pesticides, commercial fertilizers, and monoculture. It is multidisciplinary in the sense that it focuses on both the biologic and social aspects of agriculture. It focuses on four properties of agriculture systems: productivity, stability, sustainability, and equity. Especially important to this field is the incorporation of indigenous farming practices (Garí, 2001). Perhaps the most important feature of agroecology is its insistence on the integration of ecologic and social science principles in the study of agricultural systems (Dalgaard etal., 2003).

Agroecology is not a “solution” but rather a generic framework for evaluating specific local and diverse approaches (Wezel etal., 2009). Within this framework, several promising developments are taking hold. A few examples are the following.

The local food movement: One of the most successful social movements in recent decades is community supported agriculture (CSA). CSAs have many different forms, but the focus is on high quality, low environmental impact, and local farming. They depend on direct contracts between consumers and local farmers. The basic feature of a CSA is consumers who are willing to commit to buying a whole season's worth of food and farmers who are willing to work with consumers to produce the kinds of crops they want (Kleppel, 2014). According to the US Department of Agriculture, there were 7398 CSAs in the United States in 2015, accounting for 7% of direct to consumer sales by farmers (USDA, 2016).

The ugly food movement: The objective of the ugly food movement is to prevent the waste of perfectly good fruits and vegetables that do not meet the standards of appearance that consumers are used to. The move has been particularly successful in Europe. In 2014 the European Union eliminated regulations prohibiting the sale of odd or misshaped fruits and vegetables. Public information campaigned have been successful by introducing terms like “wonky,” “inglorious,” or “naturally imperfect” to promote ugly food.

http://time.com/3,761,942/why-people-are-falling-in-love-with-ugly-food/.

The healthy food movement: Has more food made people less healthy? A related question is “Is food too cheap?” According to the World Health Organization (WHO), 57 of 129 countries are struggling both with obesity and malnutrition. Eight hundred million people are malnourished worldwide, but over twice that number (2billion) are overweight or obese. The consumption of healthy food (fish, nuts, and vegetables) is declining, and people are eating too much fat, salt, and sugar (Haddad etal., 2016). Government subsidies for sugar and corn have been blamed for much of the decline in food quality. Agricultural research money is disproportionately spent on crops like maize (accounting for 45% of private sector agricultural research spending) compared to research on more nutritious fruits and vegetables. But consumers are having a tremendous effect at the retail level, and this is putting pressure on food distributors and producers to fundamentally change the way food is produced.

The FUTURE partner network

Jennifer Greenier, ... Lars Berglund, in BEST, 2020

Introduction

FUTURE is a career exploration program at the University of California, Davis, that was established with funding from the NIH BEST Initiative. The program is administered by the Clinical and Translational Science Center (CTSC) and is now fully supported by the CTSC and the School of Medicine. FUTURE is open to predoctoral graduate students and postdoctoral scholars conducting health-related research across 20 graduate programs and 29 departments in two campuses. Thus far, 131 participants in seven cohorts have enrolled in the program, representing the Schools of Medicine and Veterinary Medicine, and the Colleges of Biological Sciences, Agricultural and Environmental Science, Letters and Science, and Engineering. The centerpiece of the FUTURE program is a 10-week Career Exploration workshop series, which serves as a foundational career preparation experience for newly enrolled participants and as their introduction to a unique feature of our program, the FUTURE Partner Network. The Partner Network comprises Ph.D. professionals in non-faculty careers who contribute to the FUTURE program by sharing their career knowledge and experience with program participants. In this chapter, we'll describe the network, our data management methods, and the interactions between our program partners and participants.

From the inception of the FUTURE program, we recognized that although many trainees know that they do not want to pursue faculty research careers, they have limited knowledge of the diversity of options that are well suited for Ph.D.-trained scientists. Even in cases where they do know about particular careers, trainees often lack knowledge about how to transition into them [1]. Successful transition of Ph.D. trainees into careers of their choice requires insider information about what various careers entail, potential paths to those careers, and the skills needed to pursue them. One way of addressing this need is to connect graduate students and postdocs to Ph.D. scientists working in a broad spectrum of job categories in all major career sectors who can provide insight into interesting and fulfilling careers inside and outside of academia.

Our vision of a career preparation program for graduate students and postdocs included a network of Ph.D. scientists who had successfully navigated non-faculty career paths and who could provide trainees with windows into a variety of professions, from the known and expected to the unknown and unimagined. We aspired to build a community of Ph.D.s in the workforce who would partner with us in this effort, and eventually grow to a critical mass of professionals who adequately represented the diverse career interests of our program participants. We began recruiting partners in the second year of our program, primarily from our own professional contacts and from career-focused campus events, all while experimenting with different strategies for developing and managing our network. By the end of year 4, nearly 100 Ph.D. scientists had joined our FUTURE Partner Network, and we had refined our processes for recruitment, data management, and partner engagement.

Moringa oleifera through the years: a bibliometric analysis of scientific research (2000-2020)

Toyosi T. George, ... Fannie G. Rautenbach, in South African Journal of Botany, 2021

3.2 Global research subjects on Moringa oleifera (2000-2020)

From the data indexed on the Scopus database as represented in Fig.4, agricultural and biological sciences are ahead of the pack in terms of research outputs on MO, accounting for 23.4% of the total number. Other categories that were significantly studied are biochemistry, genetics and molecular biology (11.5%), pharmacology, toxicology and pharmaceuticals (9.9%). Although there are other articles published in different journals in the form of review articles, book chapters, letters to the editor, etc., this study is only limited to original research works as these may give a better representation of the research interests on the plant.

Agricultural waste: Review of the evolution, approaches and perspectives on alternative uses

Mónica Duque-Acevedo, ... Francisco Camacho-Ferre, in Global Ecology and Conservation, 2020

3.3 Distribution of scientific production by subject categories and journals

The evolution of the subject categories within the study of agricultural waste has been changing over the last 65 years. Agricultural and Biological Sciences is the dominant category, in which 1053 articles of the total sample are included (Fig.4). This category occupied the first position throughout the whole period analysed, except for the second period, in which it was moved down by engineering to fourth position. Environmental Sciences, which occupied fifth position in the first period (1931–1965), with only one article, was the second subject category from the second period (1966–1979), with a notable number of articles (1,053), which represented 19% of the published articles (see Figs. 6, 7, 8 and 5).

Fig.8. Keyword network based on co-occurrence for the 2006–2018 period.

In relation with these two subject categories, it is important to highlight that from the fourth period (1993–2005) to the fifth period (2006–2018), the highest increase in the number of articles associated with these categories saw a move from 364 in the fourth period to 895 in the last period for the first subject category, and from 150 to 801 for the second category. This means that 76% of the articles belonging to Environmental Sciences and 64% of Agricultural and Biological Sciences have been published in the last 13 years.

The subject category Chemical Engineering occupies third position, and groups 9% of published articles. In fourth and fifth position, with the same percentage (7%) Energy and Engineering categories are found, with 393 and 375 associated documents respectively. These five categories group 3694 articles, an amount higher than the total sample of analysed articles (3,148), this is because this research category incorporates several disciplines that have different perspectives of analysis; therefore, its classification cannot be grouped in only one category. The rest of subject categories group a total of 1764 articles, 56% of the total articles analysed. All the articles of the sample are grouped in 25 of the 27 main subject categories of Scopus (Elsevier, 2017).

The subject categories define the articles in different journals that have special interest on this research issue, although from different points of view. Table 8 shows the 25 main journals that, during the period assessed (1931–2018), have published the scientific production under analysis. A total of 1006 journals have published the 3148 articles analysed on agricultural waste and, in the last 13 years, the number of journals interested in this issue has increased considerably. In the first 13 years (1931–1965), only 11 journals published the scientific production of that period (18 articles). For the second period (1966–1979), 51 journals were added to the list, such that 104 articles of that period were published in 62 journals.

In the third period (1980–1992) 135 journals were counted. In the fourth period (1993–2005) the increase was almost doubled, 269 journals published 607 articles in that period. In the last period, from 2006 to 2018, 742 journals published the 2148 articles produced, which was 74% of the total number of journals. 45% of the journals belong to the Netherlands, 30% to the United States and only 5% of the journals come from South America. 65% of the journals come from Europe.

A high percentage of the journals (83%) belong to the Q1 quartile, according to 2018 SCImago Journal Rank (SJR) indicators. Only four of the main journals belong to the second and third quartiles. The first article of the sample analysed was published in the journal “The Journal of Agricultural Science”, whose specialty is Agricultural and Biological Sciences, Agronomy and Crop Sciences. This journal only accumulates a total of four published articles during the whole analysed period. The most recent article of the sample (December 2018), was published in the journal Current Science, whose subject category is multidisciplinary. This journal accumulates five articles of the total sample.

The “Bioresource Technology” journal has published the highest number of articles (98), which represents 3% of the total sample and places it in first position within the ranking. Furthermore, this journal has the highest number of total citations (6,643), and it appeared for the first time in the third period (1980–1992) in the 17th position in the journal list. It increased from three to 25 articles in the fourth period (1993–2005) and published 70 in the last period (2006–2018), therefore, it occupied the first position of the list in those last two periods. The first article of this journal, dated 1991, only has one associated citation (Gibbons etal., 1991).

The second journal with the highest number of articles (48) is “Soil Science Society of America Journal”, which specialises in Agricultural, Biological and Soil Sciences. This journal has a total of 2670 citations and an H index of 147. Biomass and Bioenergy Journal, with 47 documents (3032 citations), is placed in third position in the ranking. This journal, with an H index of 156, has Agricultural, Biological and Soil Sciences among its main subject categories. This journal has a total of 2670 citations and a H index of 147. Biomass and Bioenergy journal, with 47 documents (3032 citations), is placed in third position in the ranking. This journal with an H index of 156, has among its main subject categories: Agricultural and Biological Sciences, Agronomy and Crop Sciences, Renewable Energy, Sustainability and Environment and Waste Management and Elimination. The article with the highest number of citations of all the sample analysed, dated from 2004, was published in this journal (1137 citations).

The Journal of Hazardous Materials, which has 28 documents published on this issue, has the second total highest number of citations (3,933) and an average of 140.46 citations per document - the highest in the list. Among the main areas and subject categories of this journal, we find Environmental Sciences and Waste Management and Elimination. 23% of the total number of articles published on agricultural waste were published in these 25 journals.

The number of journals, as well as their evolution throughout the different periods confirms the growing importance of this issue for researchers and institutions, and also draws attention to the representatives and/or responsible persons in the media through which these articles are visualised and diffused. Good interaction and communication between scientists and society is an important support tool for research. For more than 4 decades, journals have been an important indicator for impact assessments of research studies, which are mainly considered through the number of citations (Garfield, 1979, 1998).

It is also important to highlight that journals in recent years have passed from having a specialised approach in one or few disciplines to a wider framework, which is multidisciplinary and gives more opportunities for dissemination within the scientific community (Ackerson and Chapman, 2003). In fact, one of the 27 subject categories of Scopus are “General Matter” which includes multidisciplinary journals. This is also visible in the wide range of specific subject categories in which the journals are grouped, which has increased over the last years, from 295 in 2012 to 313 in 2018 (SJR, 2019).

Multiple values and knowledge integration in indigenous coastal and marine social-ecological systems research: A systematic review

Rodolfo Dam Lam, ... Taira Stanley, in Ecosystem Services, 2019

3.3 Transdisciplinarity

There is an increasing trend towards a broader representation and collaboration between academic disciplines and fields in studies related to coastal/marine SES in indigenous settings (Fig. 3). Initially studies came from just a few fields within the environmental, agricultural, and biological sciences such as oceanography, environmental sciences, and management and policy studies. Currently studies come from a plethora of different academic disciplines and fields through academic fields such as computer sciences, economics, biochemistry, arts and humanities, and pharmacology, among others (see Table S8, Supplementary Electronic Material).

Agricultural and Biological Sciences - an overview (9)

Fig. 3. Evolution of the main academic fields represented in the reviewed studies Note: For a full list refer to Table S8 in Supplementary Electronic Material.

Fig. 4 outlines the types of institutions engaged in this type of research and presents in detail the authors’ cross-collaboration within (and between) institutions. In a sense Fig. 4 provides a snapshot of the stakeholders directly involved in the conceptualisation, design, and execution of the reviewed studies. Distinct patterns emerge when comparing between research classes. Most contextual research studies are predominately produced within academia compared to other types of institutions. Most of the collaborations tend to be between academic institutions from different countries (Fig. 4), and only in a few studies are indigenous community members integrated actively in the research team (McMillan and Prosper, 2016; Roberts et al., 2016; Suluk and Blakney, 2009). In contrast, authors from causal research studies tend to be more open to collaborations with multiple non-academic institutions such as research institutes and indigenous group agencies (e.g. traditional institutions in charge of local marine resource management) (Butler et al., 2013; Fuentes et al., 2015; Gratani et al., 2011). However, interestingly, there seems to be less collaboration with actual indigenous community members within causal research studies, compared to contextual research studies.

Agricultural and Biological Sciences - an overview (10)

Fig. 4. Collaboration between the reviewed studies authors’ institutions for each research class Note: The “arcs” represent the frequency of authors’ institutions that participated in the study. The “links” between the arcs shows the collaboration between authors’ intuitions for each study. Links that start and end within the same arc represent collaboration between the same type of institution from different countries.

The level of stakeholders’ integration also varies between research classes. Despite a lack of causal research studies in the early 2000s (we found only 1 study from 1998), they tend to integrate more stakeholders (and at a higher proportion of studies) compared to contextual research (Fig. 5). Furthermore, even though indigenous communities are the most frequently integrated stakeholders in both classes, there seems to be a different level of contribution to the actual research. Causal research studies tend to integrate more meaningfully the input of indigenous people than contextual research. Higher integration of indigenous communities through co-design approaches is observed in the causal research class (10% of all studies) rather than the contextual research class (5% of all studies). This also applies for general public participation through co-design, discussions and consultations (see Table S4, Supplementary Electronic Material, in “Indigenous People Integration”).

Stewardship as a boundary object for sustainability research: Linking care, knowledge and agency

Johan Peçanha Enqvist, ... Maria Tengö, in Landscape and Urban Planning, 2018

Appendix B Identifying records for literature review

The literature review conducted in this study used records identified through a search in the online database Scopus, on 20th March, 2017, accessed through Stockholm University. Relevant records were identified through five steps (Fig. B1).

Agricultural and Biological Sciences - an overview (12)

Fig. B1. A step-wise process to identify abstracts to be included in the literature review.

Step 1: Records identified through Scopus search for ‘stewardship’

We applied the following search protocol:

“Stewardship” in [Article Title] OR “Stewardship” in [Keywords].

Published 1990–2016.

Document type: Article or Review.

Step 2: Records’ subject areas screened for relevance

The search result was restricted to the following subject areas:

Environmental science; social sciences; agricultural and biological sciences; business, management and accounting; economics, econometrics and finance; arts and humanities; earth and planetary sciences; materials science; decision sciences; multidisciplinary.

The following subject areas were excluded:

Medicine; pharmacology, toxicology and pharmaceutics; engineering; immunology and microbiology; biochemistry, genetics and molecular biology; nursing; energy; chemical engineering; health professions; computer science; chemistry; psychology; veterinary; physics and astronomy; mathematics; neuroscience; dentistry; undefined.

This exclusion step uses a function that relies on Scopus’ classification of the articles themselves. This classification is currently not directly accessible to users, neither when viewing a specific article entry, nor when exporting the aggregate list of search hits. As described in the main text, our study instead analyzes articles based on what Subject Area its journal is assigned (see Fig. 2 in the main text). A consequence of this is that there is a small number of articles in our study that, because of the journals where they are published, are classifieds in fields like Medicine – even though this subject was excluded in the initial search. To ensure environmental relevance of the specific article, we therefore also carried out Step3.

Step 3: Records screened for ‘environmental’ relevance

We screened the remaining 1524 records based on a conventional understanding of ‘environment’ from the Online Oxford Dictionary: “the natural world, as a whole or in a particular geographical area, especially as affected by human activity” (https://en.oxforddictionaries.com/definition/environment). We deliberately adopted a rather conservative definition of ‘environment’ to limit our sample and maintain conceptual coherence.

In order to identify articles of environmental relevance, we specified this definition with keywords:

Environment in general: environment, ecosystem, ecology, nature, sustainability, conservation, green, biodiversity

Settings: landscape, land, planet, biosphere, marine, grassland, wilderness, ocean

Resources: fishing, timber, water (including watersheds, groundwater, wells, lakes) game, tree, farm, livestock, crops, wildlife, animal, aquaculture, pests/pesticides, insects/insecticides, soil

Issues/Problems: Climate Change (including ice melting and thinning), recycling (Note: not ‘waste’ in general), species loss/extinctions

We first searched for environmental relevance in the titles of the records. If the keywords were absent or environmental relevance unclear in the title, we then searched in the abstract. If the keywords were absent in the abstract and the article was clearly not of environmental relevance, we excluded the record. If the environmental relevance was still unclear, we retrieved the full-text PDF for the record and searched there. If still unclear, we interpreted the environmental relevance based on our perception of the underlying ‘intent’ of the article.

Step 4: Screened for duplicates

At this stage, the remaining 1093 records were imported from Scopus into a reference management software, Mendeley (version 1.17.9). Using the automatic inbuilt function in Mendeley, four sets of duplicates were identified and removed. Furthermore, two sets of duplicates were identified manually by visually scanning and comparing the records.

Step 5: Removal of records with no abstract.

The records were checked manually to ensure that all had abstract information. Any records without abstract information were removed. This left a total of 1002 records that were all included in the study.

Flavonoids, anthocyanins, betalains, curcumin, and carotenoids: Sources, classification and enhanced stabilization by encapsulation and adsorption

Betina Luiza Koop, ... Alcilene Rodrigues Monteiro, in Food Research International, 2022

2.6 Stabilization methods of the bioactive compounds

The Scopus Database (www.scopus.com) was used to identify the scientific methods that have been used for stabilization flavonoids, anthocyanins, betalains, curcumin, and carotenoids. Encapsulation and adsorption were the main stabilization methods found in scientific documents currently published into areas of knowledge such as Agricultural and Biological Sciences, Biochemistry, Genetics, and Molecular Biology, Pharmacology, Toxicology and Pharmaceutics, Chemistry, Medicine, Chemical Engineering, Immunology and Microbiology, Environmental Science, and Material Science. The countries that most researched on bioactive compounds were: China (30%), India (15%), the United States (15%), and Brazil (10%). From 2016 to 2020, 155.46 researches were found with the keyword bioactive compounds, from 79% were research articles, 14% reviews, 4% book chapters, and 3% conference paper, notes, among others. In addition, 27.18 patents were deposited, from 72.54% were registered in the United States Patent & Trademark Office, 11.98% in European Patent Office, 10.30% in Japan Patent Office, 4.92% in World Intellectual Property Organization, and 0.26% in the United Kingdom Intellectual Property Office.

According to Fig. 2-a, the number of scientific documents about bioactive compounds has been significantly increased in the last years. It was possible to observe a growth trend in research involving bioactive compounds being 31% for flavonoids, 28% for curcumin, 22% for carotenoids, 17% for anthocyanins, and 1% betalains. Curcumin was the bioactive compound most studied in 2020. According to Scopus Database, researches on bioactive compound stabilization techniques corresponds to only 3.85%. Fig. 2-b shows the published scientific documents on bioactive compounds and their stabilization methods.

Miscanthus in the European bio-economy: A network analysis

N. Ben Fradj, ... M. Matyka, in Industrial Crops and Products, 2020

2.1 Identification of the most relevant references

In the literature, miscanthus has been referred to in different ways. The only hybrid genotype commercially available in Europe is Miscanthus×giganteus. Nevertheless, different genotypes have been tested to optimise biomass potential, i.e. Miscanthus sinensis, Miscanthus sacchariflorus and other hybrids. Then, the bibliographic search was arranged and limited to the following terms: “Miscanthus×giganteus”, “Miscanthus sinensis”, “Miscanthus sacchariflorus” and “Miscanthus hybrids”. The references are provided by Scopus database linked to the most important publishers, such as Elsevier, Springer, and Blackwell, among others.

The query search had resulted in 2985 papers. The search was then restricted to 12 (out of 25) Scopus’ subject areas: “agricultural and biological sciences”, “environmental science”, “energy”, “chemical engineering”, “biochemistry”, “materials science”, “social sciences”, “computer sciences”, “multidisciplinary”, “business, management and accounting”, “mathematics”, “economics, econometrics and Finance”, and “decision science”. The search was limited to English and included only journal articles, book chapters, books and conference proceedings. However, no restriction has been put on the year of publication.

Given that the bibliographic search had generated a large number of studies (2239 papers), a GUI screener from METAGEAR package for R (Lajeunesse, 2017), was used to screen the abstracts and titles, thus selecting the most relevant references. After the screening, data were extracted from 1967 selected studies, first, to carry out a network analysis, and second, to analyse funding orientation in Europe (Fig. 1).

The majority of selected references are mainly published in a wide range of journals (94.2%). Conference proceedings and book chapters account for only 4.2% and 1.6%, respectively. The journals’ scopes extend to different aspects including management, environment, socio-economics, policy, bioenergy process and utilisation, and breeding (Fig. 2). Most of the papers are published in GCB Bioenergy (10.1%), Biomass & Bioenergy (8.3%), Bioresources technology (5.9%), and Industrial Crops and Products (3.3%).
