Online education is not new to the twenty-first century, especially to higher education. It is known since early 2000 and continues. Traditional education is offered in all government institutions in India. However, in March 2020, Education turned 360° immediately after the COVID-19 pandemic, which allegedly originated in Wuhan city of China in late December 2019. Since then, all the Educational Institutions including schools, colleges, universities, coaching centers insisted to shut down for an unknown time by the government to maintain social distancing and mitigating COVID-19 spread. Due to this, the traditional system was bound to shift to Online Education (OE). In this chapter, challenges that occurred due to the immediate shift to the online education system are discussed. © 2021, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.

(Elsevier B.V., 2022) Pradeep Kumar Dubey; Ajeet Singh; Rajan Chaurasia; Krishna Kumar Pandey; Amit Kumar Bundela; Gopal Shankar Singh; Purushothaman Chirakkuzhyil Abhilash
Agroecological interventions are imperative for boosting agricultural productivity and soil fertility while increasing profitability of subsistence farmers in low-income countries by replacing synthetic fertilizers. With this context, the present study was aimed to evaluate the impact of animal manures (sheep and poultry manure) and plant residue-based organic amendments (rice husk biochar and sugarcane pressmud) on soil quality, nutrient uptake and balance, yield, and sustainability of rice-wheat cropping in alluvial (rainfed) and red lateritic soil (dryland) of middle Gangetic plains (Narayanpur) and Vindhyan region (Rajgarh) of Mirzapur district in eastern UP. The field experiments were conducted for three years at the above two sites and amendments were done at a rate by replacing 30% standard recommended doses of fertilizer (RDF) for rice-wheat cropping system. Field trials were conducted with the 100% RDF as control, and 70% RDF with sheep manure, poultry manure, rice-husk biochar and sugarcane pressmud in a randomized block design. The organic amendments were done during the rice cultivation stage and the residual effect was observed during the subsequent wheat cultivation. Though soil organic carbon (SOC) was found to show significant (p ≥ 0.05) increase in biochar amended plots, animal manures followed by pressmud showed year wise increase in both SOC and microbial biomass carbon. In rainfed areas, plant growth and yield attributes for both rice and wheat were at par in amendments than control while in dryland, the 100% RDF showed better performance during the first year, after that amended plot showed better performance. All amendments resulted in higher benefit: cost ratio except biochar addition in Narayanpur, whereas in Rajgarh, the poultry manure resulted in significant improvement in benefit: cost ratio from second year onward. Our study advocates that validation of suitable amendment packages based on organic inputs are imperative for improving the yield, soil quality and nutrient balance of rice-wheat cropping system and thereby attaining the UN-SDGs at the village/local level. © 2022 Elsevier B.V.
Assessing the impact of global initiatives on current and future land restoration scenarios in India
(Academic Press Inc., 2023) Sheikh Adil Edrisi; Amit Kumar Bundela; Vivek Verma; Pradeep Kumar Dubey; Purushothaman Chirakkuzhyil Abhilash
Land degradation across the world has resulted in an unprecedented decline of ecosystem services, affecting the livelihood of 3.2 billion people globally. Sustainable land management is essential to protect our finite land resources from over-exploitation and degradation. Therefore, the present article was aimed to analyze the impacts of various national and international policies on current and future land restoration scenarios in India. A spatially explicit model (CLUMondo) was employed to predict scenarios, i.e., the ‘business as usual’ (BU) and ‘sustainable restoration’ (SR) by 2030. Though the results showed an increasing trend in land degradation, i.e., from 44.28 to 49.74 Mha during the period of 2005–15, a slight decrease was observed in 2019 (49.24 Mha), suggesting a net increase of 11.21% during the 2005–19 period. However, an increase in forest cover by 5.08% under existing policy targets overtook the degradation rate by restoration initiatives. The net decline in degraded land area by 1% with an increased forest cover by 1.83% observed during the 2015–19 periods reflected the positive impact of various national and global policies on existing restoration ventures in India. Our modeled results (weighted AUC = 0.87) also suggested an increase in forest cover by 6.9% and 9.9% under BU and SR scenarios, respectively. Under the BU scenario, degraded land will be restored up to 12.1 Mha; however, 6.27 Mha of these lands will be converted to cropland for food production. Importantly, a decrease in grasslands by 35.1% under the BU scenario warrants the urgency to maintain the integrity of such ecological systems. However, the SR scenario showed an increase in grasslands by 8.9%, with an overall restoration of degraded land up to 18.31 Mha. Moreover, a reduced cropland expansion rate of 1% suggested an effective land management response. While our results may have some uncertainties due to the model limitations, they can still be used for framing suitable land management policies to facilitate sustainable land restoration programs in India. © 2022 Elsevier Inc.

Nutritional, Ethnomedicinal, and Agricultural Significance of Neglected and Underutilized Crops from Eastern Uttar Pradesh, North India
(Multidisciplinary Digital Publishing Institute (MDPI), 2023) Ajeet Singh; Amit Kumar Bundela; Purushothaman Chirakkuzhyil Abhilash
Meeting food and nutritional security needs for a growing population is a global sustainability challenge due to the heavy reliance on a few cultivated crops for dietary requirements across the world. To ensure local food security, it is imperative to diversify dietary options with locally available, neglected, and underutilized crops (NUCs) with nutritional and biocultural significance. In this context, the present study aims to explore the role of NUCs for nutritional, ethnomedicinal, and agricultural relevance in two districts of eastern Uttar Pradesh, i.e., Mirzapur and Sonebhadra. Extensive field surveys were conducted in the study sites, and a total of 445 local respondents were interviewed based on structured questionnaires for calculating ethnobotanical indices, i.e., relative frequency of citation (RFC), frequency of citation (FC), use report (UR), and cultural importance index (CI) of NUCs. The study identified 116 NUCs belonging to 55 families and 103 genera. All reported NUCs had medicinal value; 55 were edible and used as food; and 41 had agricultural significance. Leaves were the most commonly used plant parts for medicinal purposes, followed by roots and stems, whereas flowers were the least commonly used parts. NUCs were used by the locals for their medicinal properties to treat various ailments, such as skin and eye problems, headaches, and liver problems. They were administered as decoction, paste, vapor inhalation, fruit juice, and poultice. The RFC, FC, UR, and CI values of the NUCs were in the range of 12 to 365, 0.03 to 0.82, 12 to 394, and 0.03 to 0.89, respectively. Fruits were the most commonly consumed part, followed by leaves, tubers, pods, and aerial bulbs, whereas the mode of consumption was stir-fry, soup, vegetables, salad, or in raw form. NUCs were bestowed with essential macro- and micronutrients and were found in the range of Ca (3.79–1147.3), K (2.6–1600.3), Mg (0.8–468.0), Na (0.4–270.8), P (1.15–305), Fe (0.1–327.6), Zn (0.1–84.6), Cu (0.047–33.3), Mn (0.1–62.3) mg/100 g, and vitamins like ascorbic acid (0.04–1561.1), thiamine (0.041–2.4), and β-Carotene (0.2–93.6) mg/100 g. These NUCs were cultivated in different settings, such as kitchen gardens, backyard gardens, border crops, and sometimes agricultural fields. The current study reveals the rich diversity and varied use of these NUCs with respect to their ethnomedicinal, nutritional, and agricultural relevance. Sustainable utilization with large-scale cultivation of promising NUCs can lead to local food security and the subsequent attainment of the associated UN Sustainable Development Goals. © 2023 by the authors.
Planet friendly agriculture: Farming for people and the planet
(Elsevier B.V., 2021) Pradeep Kumar Dubey; Ajeet Singh; Rajan Chaurasia; Krishna Kumar Pandey; Amit Kumar Bundela; Rama Kant Dubey; Purushothaman Chirakkuzhyil Abhilash
Agriculture is central to overall development of humankind and plays a decisive role in the timely realization of several UN-Sustainable Development Goals. Nevertheless, agriculture is the largest nonpoint source of pollution primarily due to rampant use of agrochemicals, and contributes ~34% of the annual greenhouse gases emission globally. Agricultural practices are also one of the major drivers of global biodiversity loss, and exerts a heavy footprint on water amounting to 70% of the world's freshwater withdrawal annually. As per projections of the Food and Agricultural Organization of the United Nations, agricultural production has to be doubled by the year 2050 to feed a global population of ~9.7 billion. However, this intensification must be done in an ecological way (not at the cost of planetary resilience) while designing novel strategies to reinforce agriculture's crucial role in achieving Global Goals. Hence, the notion of ‘planet friendly agriculture’ wherein food production has to be achieved within the planetary boundaries is getting global priority as a transitional as well as transformative solution for improving the wellbeing of people while safeguarding life-supporting systems of a heavily polluted, overexploited and resource crunched planet. This graphical review aimed to portray various planet friendly farming practices based on resource conservation and replenishment to strengthen food and nutrition security of the current and future generation while reducing pollution, greenhouse gases emission, biodiversity loss, and water footprint, even under changing climatic conditions. © 2021 The Author(s)
Seed enhancement technologies for sustainable dryland restoration: Coating and scarification
(Elsevier B.V., 2023) Heba Jarrar; Ali El-Keblawy; Chaouki Ghenai; P.C. Abhilash; Amit Kumar Bundela; Zainul Abideen; Mohamed S. Sheteiwy
High temperatures, soil salinity, a lack of available water, loose soils with reduced water holding, and low soil fertility are obstacles to restoration efforts in degraded drylands and desert ecosystems. Improved soil physical and chemical properties, seed germination and seedling recruitment, and plant growth are all proposed as outcomes of seed enhancement technologies (SETs). Seed priming, seed coating, and seed scarification are three SETs' methods for promoting seed germination and subsequent plant development under unfavorable environmental conditions. Various subtypes can be further classified within these three broad groups. The goals of this review are to (1) develop a general classification of coating and scarification SETs, (2) facilitate the decision-making process to adopt suitable SETs for arid lands environments, and (3) highlight the benefits of coating and scarification SETs in overcoming biotic and abiotic challenges in ecological restoring degraded dryland. For rehabilitating degraded lands and restoring drylands, it is recommended to 1) optimize SETs that have been used effectively for a long time, particularly those associated with seed physiological enhancement and seed microenvironment, 2) integrate coating and scarification to overcome different biotic and abiotic constraints, and 3) apply SET(s) to a mixture of seeds from various species and sizes. However, more research should be conducted on developing SETs for large-scale use to provide the required seed tonnages for dryland restoration. © 2023 Elsevier B.V.
The trilogy of wild crops, traditional agronomic practices, and un-sustainable development goals
(MDPI AG, 2020) Ajeet Singh; Rama Kant Dubey; Amit Kumar Bundela; Purushothaman C. Abhilash
The world population is projected to become 10 billion by the end of this century. This growing population exerts tremendous pressure on our finite food resources. Unfortunately, the lion-share of the global calorie intake is reliant upon a handful of plant species like rice, wheat, maize, soybean and potato. Therefore, it is the need of the hour to expand our dietary reliance to nutritionally rich but neglected, underutilized and yet-to-be-used wild plants. Many wild plants are also having ethnomedicinal and biocultural significance. Owing to their ecosystem plasticity, they are adapted to diverse habitats including marginal, degraded and other disturbed soil systems. Due to these resilient attributes, they can be considered for large-scale cultivation. However, proper biotechnological interventions are important for (i) removing the negative traits (e.g., low yield, slow growth, antinutritional factors, etc.), (ii) improving the positive traits (e.g., nutritional quality, stress tolerance, etc.), as well as (iii) standardizing the mass multiplication and cultivation strategies of such species for various agro-climatic regions. Besides, learning the biocultural knowledge and traditional cultivation practices employed by the local people is also crucial for their exploitation. The Special Issue “Wild Crop Relatives and Associated Biocultural and Traditional Agronomic Practices for Food and Nutritional Security” was intended to showcase the potential wild crop varieties of nutritional significance and associated biocultural knowledge from the diverse agroecological regions of the world and also to formulate suitable policy frameworks for food and nutritional security. The novel recommendations brought by this Special Issue would serve as a stepping stone for utilizing wild and neglected crops as a supplemental food. Nevertheless, long-term cultivation trials under various agro-climatic conditions are utmost important for unlocking the real potential of these species. © 2020 by the authors.
