Spatio-Temporal Evolution and Driving Factors of "Non-Grain Production” in Hubei Province Based on a Non-Grain Index

Non-grain production (NGP) on cultivated land has become a common phenomenon due to the prosperity of the rural economy and the optimisation of the agricultural structure. However, the excessive use of cultivating land for NGP has threatened food production and the sustainable use of cultivated land. To halt this trend and to ensure food security, the authors of this paper applied a novel non-grain index to measure NGP, which could reflect multiple NGP activities;designated Hubei Province as its object of research;and revealed NGP's spatio-temporal patterns of the past 30 years. We then assessed the characteristics of NGP based on spatial autocorrelation analysis, the Theil index, and geographically weighted regression. The results showed that the value of the non-grain index grew from 0.497 to 1.113 as NGP increased significantly in Hubei Province. The number of high-NGP counties increased, spatial agglomeration became obvious, and the eastern and western sides of Hubei Province witnessed an observable growth in NGP. As a result, the NGP in the eastern and western regions overtook production in the central region. Despite a series of historical subsidy policies and agricultural modernisation initiatives that promoted the planting of grain crops, the policy of "grain on valuable cultivated land” could be better implemented. We conclude by making some suggestions for reducing NGP and protecting cultivated land.

Taiwan's Food Resiliency - or Not - in a Conflict with China

The US military, intelligence, and diplomatic communities have overlooked a key vulnerability in their assessment of a potential military conflict between China and Taiwan- Taiwan's growing reliance on agricultural imports and its food stocks (except for rice) that could endure trade disruptions for only six months. This article assesses Taiwan's agricultural sector and its ability to feed the country's population if food imports and production are disrupted;identifies the food products that should be prioritized in resupply operations, based on Taiwan's nutritional needs and domestic food production;and outlines the required logistical assets. These findings underscore the urgency for US military planners to develop long-term logistical solutions for this complex strategic issue.

Trans/feminist collaborative autoethnographic storying of gender-based violence, during the COVID-19 pandemic

In this paper, we reported on the lattice distortion, surface morphologies, vacancy defects and electrochemical performance that had been observed in Na3V2(PO4)2F3 prepared at different annealing temperatures. X-ray diffraction indicated that all the samples were single phase materials with tetragonal structure and exhibited lattice distortion with the increase of annealing temperatures. A possible mechanism causing the strain-induced lattice distortion had been discussed. Moreover, scanning electron microscopy and positron annihilation techniques were used to study the grain size and vacancy defects as a function of annealing temperatures. The superior electrochemical performance of Na3V2(PO4)2F3 electrode was obtained at the annealing temperature of 350 degrees C with 167.73 F center dot g-1 specific capacitance and 85% capacitance retention. The better electrochemical performance was due to the synergistic effects of grain size and vacancy defect regulated by the annealing temperatures. These results could provide experimental basis for enhancing electrochemical performance of Na3V2(PO4)2F3 in sodium-ion battery area applications. (c) 2023 Elsevier B.V. All rights reserved.

Calculation of Electrostatic Potential Field of Coronavirus S Proteins for Brownian Dynamics Simulations

The Brownian dynamics method can give insight into the initial stages of the interaction of antiviral drug molecules with the structural components of bacteria or viruses. RAM of conventional personal computer allows calculation of Brownian dynamics of interaction of antiviral drugs with individual coronavirus S protein. However, scaling up this approach for modeling the interaction of antiviral drugs with the whole virion consisting of thousands of proteins and lipids is difficult due to high requirements for computing resources. In the case of the Brownian dynamics method, the main amount of RAM in the calculations is occupied by an array of values of the virion electrostatic potential field. When the system is increased from one S protein to the whole virion, the volume of data increases significantly. The standard protocol for calculating Brownian dynamics uses a three-dimensional grid with a spatial step of 1°A to calculate the electrostatic potential field. In this work, we consider the possibility of increasing the grid spacing parameter for calculating the electrostatic potential field of individual coronavirus S proteins. In this case, the amount of RAM occupied by the electrostatic potential field is reduced, which makes it possible to use personal computers for calculations. We performed Brownian dynamics simulations of interaction of an antiviral photosensitizer molecule with S proteins of three coronaviruses SARS-CoV, MERS-CoV, and SARS-CoV-2, and demonstrated that reduction of detalization of electrostatic potential field does not influence the results of Brownian dynamics much © The Authors 2022.

Healthy for Life: A Shift to Virtual Nutrition Education to Improve Confidence and Dietary Behaviors

Introduction: Less than 10% of U.S. adults meet the guidelines for whole grains, fruits, and vegetables each day. The Healthy for Life community-based program aims to change confidence and health behaviors, by equipping individuals with new skills for healthy living. As a result of the COVID-19 pandemic in 2020 and 2021, the program pivoted from in-person to a virtual implementation model. This required more advanced planning due to additional logistics to ensure a skills-based learning environment. Objective(s): To examine the effectiveness of the Healthy for Life program over time, specifically: o Changes in participant confidence in the preparation of healthy foods at home o Changes in participant consumption of fruits, vegetables, and whole grains o Changes in participant frequency of healthy shopping habitsMethods: A community engagement program was implemented and evaluated in 17 community centers in 2020-2021 to measure changes in participant confidence to prepare healthy meals at home, consumption of fruits, vegetables and whole grains, and frequency of healthy shopping habits. Community center facilitators administered the same pre/post survey to participants at the first educational experience, and then again at the final experience. Facilitators entered the participant data into an online survey portal. Analysis was conducted with 235 participants who completed both pre and post surveys. Two-way repeated ordinal regression was used to assess changes in key metrics over time. Result(s): Participants were predominately female (90.6%), about two-thirds (65.2%) were between 25-55 years old, and most identified as non-Hispanic White/Caucasian (42.6%) or Black/African American (35.7%). Close to half (45.9%) of participants had a college degree or higher, over a quarter (28.1%) received benefits from SNAP and/or WIC, and more than two-thirds (63.8%) indicated they are the only person in their household preparing meals. Almost half (49.3%) of respondents attended the suggested minimum of 4 educational experiences. On average, respondents statistically significantly increased their daily fruit & vegetable consumption by 1.21 serving(s). In addition, over one-third (34%) of respondents increased their level of confidence to prepare healthy meals at home and (37%) respondents increased their level of confidence to substitute healthier cooking and food preparation methods. Close to half (47.2%) respondents reported increased frequency of reading food labels and checking the nutritional values when purchasing food. Conclusion(s): Despite the shift to virtual implementation, the Healthy for Life community education program, was still effective in improving participant confidence and dietary behaviors over time. However, additional research studies are required to further assess whether virtual implementation of this type of intervention will continue to be effective.

Analysis of the Factors Influencing the Stability of Stored Grains: Implications for Agricultural Sustainability and Food Security

The recent unprecedented situations like the COVID-19 pandemic and the Russia-Ukraine war have severely impacted food security and grain production in emerging economies. These countries can try to import grains to enhance secure food security, but this will strain their dollar reserve and endanger their financial stability. Under such circumstances, the adoption of sustainable grain storage practices is essential to reducing the unusual gap between grain production and grain availability. This research, therefore, explores the key factors that may affect the stability of stored grains to promote agricultural sustainability and food security in emerging economies. First, the study identifies the significant factors that influence the stability of stored grains from an emerging economy perspective. Then, the study employs an integrated approach consisting of Pareto analysis, fuzzy-based Total Interpretive Structural Modeling (TISM), and Cross-Impact Matrix Multiplication Applied to Classification (MICMAC) analysis. Based on the literature review and expert feedback, nineteen factors were initially identified. After employing Pareto analysis, the top thirteen factors have been further analyzed using fuzzy TISM- fuzzy MICMAC to examine their interrelationships. The study findings indicate that "Proper training on advanced storage operations” is the most significant factor influencing sustainable grain storage operations. The study insights can help practitioners to focus more on the crucial aspects of the grain storage operation and can assist the policymakers and industry leaders of emerging economies in strategic decision-making to achieve agricultural sustainability and thus improve food security.

Therapeutic and Dietary Support for Gastrointestinal Tract Using Kefir as a Nutraceutical Beverage: Dairy-Milk-Based or Plant-Sourced Kefir Probiotic Products for Vegan and Lactose-Intolerant Populations

Kefir is a fermented milk beverage different in consistency and taste from other popular milk-product yogurt. Unlike yogurt prepared using lactic acid bacteria in fermentation, milk is fermented for kefir production using preculture in the form of kefir grains. Therefore, the metabolic activities of a mixed culture, including strains of bacteria and yeast, contribute to the probiotic characteristics in kefir. This article is based on the review of published studies on the functionality and nutraceutical properties of kefir. The therapeutic and dietary properties of kefir beverage and its probiotic strains have been discussed for their several health benefits. Concise selected information mostly from recent reports has been presented for two categories of kefir products: milk used for the production of dairy-based traditional kefir beverages for the lactose-tolerant population, and the plant-sourced substrates used for the production of dairy-free kefir beverages for lactose-intolerant and vegan consumers.

RESISTANCE OF SARS COV-2 TO SEAWATER

In this study, it was aimed to comparatively investigate the grain properties of shoe upper leathers produced for different purposes. Thus, six different types of shoe upper leather (cracked, antique, patent, nappa, nubuck, printed) were provided from three different footwear companies. The tensile strength and elongation at break (TS EN ISO 3376), single and double edge tear strength (TS EN ISO 3377-1, TS EN ISO 3377-2), cracking and bursting resistance (TS 4137 EN ISO 3378, TS EN ISO 3379), flex resistance (TS EN ISO 5402-1) as well as dry and wet rubbing fastness tests (TS EN ISO 11640) were applied to leathers that have similar thicknesses. The results of the study gave information about the physical strength and product performances of different upper leather types. The data were evaluated comparatively and the effects of shoe upper leather types on quality and performance were evaluated. © 2022 Toate drepturile asupra acestei ediţii sunt rezervate editorilor.

Return connectedness and multiscale spillovers across clean energy indices and grain commodity markets around COVID-19 crisis.

The aim of this paper is to examine the return connectedness and multiscale spillovers between the Clean Energy Index and the grain commodity market around COVID-19. Using daily data from January 4, 2017 to July 1, 2022, a time-varying parametric vector autoregressive (TVP-VAR) connectedness approach is first used to reveal connectedness patterns before and during COVID-19. We further used Baruník and Krehlík (2018)'s frequency domain spillover method to assess connectedness in different domain horizons. Our results show spillover effects over time and frequency, with COVID-19 significantly affecting the connectedness of the whole system. Dynamic connectedness peaks significantly after sudden bursts of COVID-19, validating the reported uncertainty. We also documented higher spillover levels in the short term than in the medium and long term. In addition, We find that (i) most clean energy indices are positively affected by the COVID-19 outbreak; (ii) the NASDAQ OMX Bio/Clean Fuels Index and NASDAQ OMX Geothermal Index send spillovers to all grain commodities throughout the sample period, while the WilderHill Clean Energy Index and NASDAQ OMX Wind Energy Index indices are the largest recipients of spillovers from other markets regardless of time horizon; (iii) the OMX Bio/Clean Fuels and OMX Geothermal Energy indices dominate spillover shocks to grain commodity markets. This is the first study to analyse the connectedness and time-frequency dynamics of returns in the green energy index and the grain commodity market. These results provide valuable insights to investors and key policymakers, especially at a time of more significant uncertainty.

Improving cardiovascular health behaviors through a comprehensive lifestyle intervention program during the pandemic in India

Background: We have witnessed a dramatic dip in adherence to cardiovascular health behaviors during the COVID-19 pandemic. Data from across the globe has shown that risk factors for cardiovascular disease (CVD) such as decreased physical activity, poor diet, and increased depression, loneliness, and stress have peaked during the pandemic. Having been badly affected by the pandemic and having had prolonged periods of countrywide lockdown, the at-risk and established CVD population has faced a major challenge in adhering to a healthy lifestyle in India. Purpose(s): This study aimed to analyze the change in cardiovascular health behaviors brought about by a comprehensive lifestyle intervention program (CLIP) during the pandemic in India. Method(s): All at-risk and CVD patients who had participated in the CLIP from mid 2020 to mid 2022 and had completed the internally validated health behavior assessment questionnaire, pre and post-program, were included in this retrospective study. A multidisciplinary team consisting of Physician, Physiotherapist, Dietician, and Counseling Psychologist provided the sessions online and/or in-person for the home-based and hybrid programs respectively. When a combination of online and in-person sessions were provided for a subject, it was called a hybrid program. The core components of the CLIP were exercise training, education on relevant health topics, nutritional guidance and psychosocial counseling. Result(s): Age of the subjects (n=50) at enrolment was 54+/-13 years and 40 (80%) were male. The time between pre-program and post-program assessments was 110 (IQR 47) days. Number of at-risk and CVD patients attending home-based and hybrid programs are shown in the Figure. There were 4 couples in the study cohort;21 (50%) of the remaining 42 subjects had at least 1 other family member attend the majority of sessions. There was a significant improvement in all the cardiovascular health behaviors, namely adequate daily intake of fruits, vegetables and whole grains, choice of heart-healthy foods between meals, sufficient weekly exercise and a reduction in self-reported chronic stress, upon completion of the CLIP (Table). Conclusion(s): A comprehensive lifestyle intervention program that incorporates a multipronged approach to behavior modification is effective in improving cardiovascular health behaviors in individuals at-risk as well as with established cardiovascular disease in India. The ripple effect of behavior modification in the accompanying family members needs to be studied systematically.

Trends in rice research: 2030 and beyond

Rice production and research have met unprecedented challenges in recent years. Yield and total production have plateaued for many years in some major producing rice-producing countries while the demand from populations in poverty is ever increasing. For example, more than 100 million additional people became extremely poor, mostly from Asia and sub-Saharan Africa in 2020 alone. Rice is not only the calorie source for half of the global population but also the key staple food for the world's poorest and undernourished people living in Asia and Africa. In this review, we have analysed the trends in rice research in the past three decades, particularly on the mega-projects that attempted to revolutionize rice yield, sustainability and quality of both Asian (Oryza sativa) and African (O. glaberrima) rice, with their impact on rice cultivation. We have also analysed the trends in population growth, rice cultivation, production, price and consumption along with their projections for 2030 and beyond. Furthermore, we have analysed recent trends in variety release using Bangladesh as an example. Finally, we have identified the future challenges and priorities of rice research.

Changes in per capita wheat production in China in the context of climate change and population growth.

To address challenges associated with climate change, population growth and decline in international trade linked to the COVID-19 pandemic, determining whether national crop production can meet populations' requirements and contribute to socio-economic resilience is crucial. Three crop models and three global climate models were used in conjunction with predicted population changes. Compared with wheat production in 2000-2010, total production and per capita wheat production were significantly (P < 0.05) increase in 2020-2030, 2030-2040 and 2040-2050, respectively, under RCP4.5 and RCP8.5 due to climate change in China. However, when considering population and climate changes, the predicted per capita production values were 125.3 ± 0.3, 127.1 ± 2.3 and 128.8 ± 2.7 kg during the 2020-2030, 2030-2040, 2040-2050 periods under RCP4.5, or 126.2 ± 0.7, 128.7 ± 2.5, and 131.0 ± 4.1 kg, respectively, under RCP8.5. These values do not significantly differ (P > 0.05) from the baseline level (127.9 ± 1.3 kg). The average per capita production in Loess Plateau and Gansu-Xinjiang subregions declined. In contrast, per capita production in the Huanghuai, Southwestern China, and Middle-Lower Yangtze Valleys subregions increased. The results suggest that climate change will increase total wheat production in China, but population change will partly offset the benefits to the grain market. In addition, domestic grain trade will be influenced by both climate and population changes. Wheat supply capacity will decline in the main supply areas. Further research is required to address effects of the changes on more crops and in more countries to obtain deeper understanding of the implications of climate change and population growth for global food production and assist formulation of robust policies to enhance food security.

Caught off guard and beaten: The Ukraine war and food security in the Middle East.

The Ukraine war has led to a severe global food crisis due to complex supply disruptions and price increases of agricultural inputs. Countries of the Middle East have been directly affected because of their high dependence on food imports from Russia and Ukraine. Furthermore, this food crisis comes at times of high baseline vulnerability due to the compound impacts of COVID-19, repeated food shocks, and weakened states due to political-economic difficulties. This paper provides a detailed analysis of the food-related vulnerability of Middle Eastern countries in the wake of the Ukraine war. It contextualizes the varying impacts of this crisis in the region, and highlights country-level response strategies. The analysis shows a concerning and deepened crisis in the case of highly exposed and politically fragile countries with weakened food sectors; e.g., Lebanon, Sudan, and Yemen. Political-economic instabilities, limited domestic agriculture, and the lack of reliable grain reserves have aggravated the current food crisis in some countries. At the same time, indigenous short-term responses related to regional aid and cooperation have emerged, particularly in the Gulf countries, which have witnessed soaring revenues from higher energy prices. Alongside more regional frameworks for collaboration on food security, future action to mitigate such food crises should include the strengthening of local sustainable agriculture, storage capacities, and grain procurement strategies from international suppliers.

Navadhanya Functional Traditional Foods : Perfect Healthy Snacks during Covid-19 Pandemic

The fast food dietary life style habits had rapidly put the people in the midst of risky conditions especially showed adverse impacts on snacks. Most of the Indian traditional foods typically contains highly nutritious indigenous foods and bringing slight variation in ingredients formulations proved to be more functional. Navadhanya in the Indian culture occupies auspicious place and provide numerous nutritional and therapeutic benefits. In fact, the current pandemic COVID-19 pandemic scenario requires healthy snacking behaviour. Based on this background, the common traditional foods viz., boondhi laddu, mysorepak, kajjikayalu and muruku were purposefully chosen to develop functional foods with the incorporation of navadhanya mix at 50 per cent level. The acceptability studies carried out organoleptically both at the baseline and after storage period of one week had clearly demonstrated highly acceptable mean organoleptic scores and not significant difference statistically. The findings well explained the retention of freshness even at one-week storage period. On the other hand, the nutrient analysis carried out had shown sufficient evidence that the functional foods prepared were energy dense and rich in essential nutrients such as protein, fat, calcium and iron. Promotion of indigenous healthy foods not only improves healthy but also play crucial role in the attainment of food and nutrition security. Copyright © 2022, Anka Publishers. All rights reserved.

A Study on the Spatial-Temporal Evolution and Driving Factors of Non-Grain Production in China's Major Grain-Producing Provinces.

Food self-sufficiency in a large country with 1.4 billion people is very important for the Chinese government, especially in the context of COVID-19 and the Russian-Ukrainian conflict. The objective of this paper is to explore the spatial-temporal evolution and driving factors of non-grain production in thirteen major grain-producing provinces in China, which account for more than 75% of China's grain production, using 2011-2020 prefecture-level statistics. In the present study, the research methodology included GIS spatial analysis, hot spot analysis, and spatial Durbin model (SDM). The findings of this study are as follows: (1) The regions with a higher level of non-grain production were mainly concentrated in the central and western regions of Inner Mongolia, the middle and lower reaches of Yangtze River and Sichuan, while the regions with a low level of non-grain production were mainly distributed in the Northeast Plain. The regions with a higher proportion of grain production to the national total grain production were concentrated in the Northeast Plain, the North China Plain, and the Middle and Lower Yangtze River Plain of China. The hot spot regions with changes in non-grain production levels were mainly distributed in the Sichuan region and Alashan League City in Inner Mongolia, and the cold spot regions were mainly distributed in Hebei, Shandong, Henan, and other regions. (2) An analysis of the SDM indicated that the average air temperature among the natural environment factors, the ratio of the sum of gross secondary and tertiary industries to GDP, the ratio of gross primary industry to the GDP of economic development level, the urbanization rate of social development, and the difference in disposable income per capita between urban and rural residents of the urban-rural gap showed positive spatial spillover effects. The grain yield per unit of grain crop sown area of grain production resource endowment, the total population of social development, and the area sown to grain crops per capita of grain production resource endowment all showed negative spatial spillover effects. The research results of this paper can provide a reference for the country to carry out the governance of non-grain production and provide a reference for China's food security guarantee.

Acceptability of zinc biofortified wheat and flour among farmers in Pakistan: experiences from the BiZiFED2 project

In Pakistan, 24.3% of women of reproductive age and 19.5% of children aged under five living in rural areas are zinc deficient(1). Zinc-biofortified wheat flour may be an effective approach to address zinc deficiency in i communities where access to zinc-rich foods is low(2). Key to successful scaling up of biofortified wheat and flour is its acceptability and adoption among its potential consumers and producers(3). A convergent mixed methods study(4) was conducted parallel to the BiZiFED2 cluster- randomised controlled trial(5) in the Peshawar region between November 2020- July 2021. Two semi- structured focus group discussions (FGDs) were conducted with farmers who grew Zincol-2016 wheat for the RCT(5). FGDs were audio-recorded, transcribed, and translated into English. Transcripts were analysed using thematic analysis(6). In addition, a total of 686 farmers located in Pakistan's main wheat growing region, Punjab province, were invited to participate in a survey. These farmers were growing Zincol-2016 as part of a soil-mapping exercise within the broader BIZIFED programme. The survey was designed to capture the farmer's experiences of growing Zincol-2016 in the growing season 2019-2020 and whether they continued to grow it during the subsequent season.418 farmers participated in the survey (61% participation rate), and 12 in the FGDs. Survey data showed that 47% of participants reported growing Zincol-2016 in the subsequent season. Drivers of Zincol-2016 cultivation that were most frequently described as important were: availability of new seed (100%), grain yield (98%), growth and disease resistance (97%), quality of flour from the previous harvest (96.6%), and nutritional benefit (94.5%). Fewer farmers reported cost of the seed (71%) and market demand (57%) as important. A high proportion of farmers reported consuming Zincol-2016 within their own household (79%), and those who consumed Zincol-2016 flour claimed that it had better taste (90%) and texture (79%) than their usual flour. Qualitative analysis of the FGD data revealed that enablers for scaling up include: the value ascribed to the flour's health benefits, perceived improved quality of grain and production, and willingness to produce biofortified wheat if support is provided (i.e., resources and training). Challenges and considerations for scaling up include unfamiliarity with the biofortification process, production costs, external threats to the supply chain and production of wheat (i.e., COVID-19, weather, plant disease), and acceptance and support from the landlord. Results from this mixed-methods study suggest that farmers appeared to value biofortified wheat and flour and may be willing to produce and consume it if resources and training were provided.

Towards an optimal monoclonal antibody with higher binding affinity to the receptor-binding domain of SARS-CoV-2 spike proteins from different variants.

A highly efficient and robust multiple scales in silico protocol, consisting of atomistic Molecular Dynamics (MD), coarse-grain (CG) MD, and constant-pH CG Monte Carlo (MC), has been developed and used to study the binding affinities of selected antigen-binding fragments of the monoclonal antibody (mAbs) CR3022 and several of its here optimized versions against 11 SARS-CoV-2 variants including the wild type. Totally 235,000 mAbs structures were initially generated using the RosettaAntibodyDesign software, resulting in top 10 scored CR3022-like-RBD complexes with critical mutations and compared to the native one, all having the potential to block virus-host cell interaction. Of these 10 finalists, two candidates were further identified in the CG simulations to be the best against all SARS-CoV-2 variants. Surprisingly, all 10 candidates and the native CR3022 exhibited a higher affinity for the Omicron variant despite its highest number of mutations. The multiscale protocol gives us a powerful rational tool to design efficient mAbs. The electrostatic interactions play a crucial role and appear to be controlling the affinity and complex building. Studied mAbs carrying a more negative total net charge show a higher affinity. Structural determinants could be identified in atomistic simulations and their roles are discussed in detail to further hint at a strategy for designing the best RBD binder. Although the SARS-CoV-2 was specifically targeted in this work, our approach is generally suitable for many diseases and viral and bacterial pathogens, leukemia, cancer, multiple sclerosis, rheumatoid, arthritis, lupus, and more.

Optimized Ridge–Furrow Ratio to Decrease Greenhouse Gas Emissions and Increase Winter Wheat Yield in Dry Semi-Humid Areas

The plastic-mulched ridge–furrow rainwater harvesting (RF) system has been widely adopted worldwide due to its visible economic benefits. However, few and inconclusive studies have focused on greenhouse gas (GHG) emissions. In addition, it is still unknown whether different coverage ratios under RF have an impact on greenhouse gas emissions. Here, we evaluate the effects of various coverage ratios on the soil hydrothermal characteristics, global warming potential (GWP), greenhouse gas intensity (GHGI), and yield productivity in dry semi-humid areas. A control (FP, conventional flat planting without mulching) and three different ridge–furrow ratios (40:40 (RF40), 40:60 (RF60), and 40:80 (RF80)) were tested in 2017–2019. Compared with FP, RF increased the soil temperature and promoted soil moisture in the furrows during the vegetative growth period. However, the soil temperature of the furrows slightly increased with furrow width, whereas the soil moisture obviously decreased under the three RF practices. In a wet year (2017–2018), FP significantly increased the winter wheat yield (43.6%) compared with RF, while the opposite was the case in a normal year (2018–2019). Among the three RF treatments, RF40 and RF80 significantly increased the yield by 13.9% and 17.2%, respectively, compared with RF60. Compared with FP, all of the RF treatments increased the flux of N2O and CO2 emissions but reduced CH4 absorption. Compared with FP, RF with ridge–furrow ratios of 40:40 cm, 40:60 cm, and 40:80 cm increased the GWP by 99.6%, 53.4%, and 31.3%, respectively, and increased the GHGI by 55.8%, 45.3%, and 0.7%, respectively. Therefore, conventional flat planting in wet years and a ridge–furrow ratio of 40:71 cm in normal years can reduce GHG emissions, sustaining crop productivity, and promote the sustainable development of agriculture and the environment.

Herbal Sources of Magnesium as a Promising Multifaceted Intervention for the Management of COVID-19

The coronavirus-disease 2019 (COVID-19) was announced as a global pandemic by the World Health Organization (WHO), and it affected all human groups. Severe COVID-19 is characterized by cytokine storms, which can lead to multiorgan failure and death, although fever and cough are the most typical symptoms of mild COVID-19. Plant-based diets provide a 73% lower risk of moderate-to-severe COVID-19. Additionally, the association between low levels of some micronutrients and the adverse clinical consequences of COVID-19 has been demonstrated. So, nutritional therapy can become part of patient care for the survival of this life-threatening disease (COVID-19) also short-term recovery. Magnesium as an essential micronutrient due to its anti-inflammatory and beneficial effects can effectively prevent COVID-19 pandemic by playing a role in the treatment of comorbidities such as diabetes and cardiovascular disorders as major risk factors for mortality. Sufficient magnesium to stay healthy is provided by a proper daily diet, and there is usually no need to take magnesium supplements. Considering that almost half of the dietary magnesium comes from fruits, vegetables, nuts, and grains, it seems necessary to pay attention to the consumption of edible plants containing sufficient magnesium as part of the diet to prevent severe COVID-19. In this study, we have described the beneficial effects of sufficient magnesium levels to control COVID-19 and the importance of plant-based magnesium-rich diets. Additionally, we have listed some edible magnesium-rich plants.
