    Biotechnological strategies to generate climate-smart crops: Recent advances and way forward
    (John Wiley & Sons, 2023) Maurya, Jyoti; Singh, Roshan Kumar; Prasad, Manoj
    Industrialization and other man-made actions caused accumulation of greenhouse gases in the atmospheric troposphere layer, leading to enhanced greenhouse effect and hike in average global temperature in response. This led to unpredicted and frequent occurrences of rainfall, droughts, floods, and other climatic events. Changing climate has imposed direct abiotic stresses leading severe threat to global crop production either directly (morpho-physio-chemical effects) or indirectly (socioeconomic effects) and caused food insecurity worldwide. Moreover, these climate change effects are predicted to become more severe in the future. So, to ensure the global food security, development of climate-smart crops is an urgent need. Biotechnology-based approaches have paved the way to understand the role of different genes and their applications to achieve climate change induced stress tolerance and developed crops for sustainable agriculture in the present scenario. Keeping this in mind, the present book chapter briefs about the effect of climate change on crop growth, development, and yield, as well as plant responses and adaptations during changing environments. This chapter also discusses different strategies implied to combat the climate change and highlights the integrative-omics based approach and biotechnological strategies, as well as their advancements toward generating the climate-smart crops.

    The promise of millets in the twenty-first century: emphasis on breeding, nutrition, food security and sustainability
    (Springer Nature Publishing AG, 2023) Bandyopadhyay, Tirthankar; Singh, Roshan Kumar; Ramesh, Palakurthi; Maurya, Jyoti; Prasad, Manoj
    Global population is expected to cross 11 billion by the turn of the century, which has put immense pressure on the existing agricultural systems worldwide. This is complicated by gradually decreasing productivity and acreage as a result of climate change in addition to ever-increasing input costs of resource hungry staple crops like rice, wheat, and maize. Unfortunately, the most affected by these events are those who have the least resources at their disposal to mitigate the issue, especially in countries of Asia and Sub-Saharan Africa. It is therefore pertinent to explore and adopt alternative and/or complementary crops that are easier to cultivate, climate change tolerant, less resource hungry, nutritionally richer for human consumption, and agriculturally sustainable. Millets are perfect cereal crops which meet all of these requirements and can realistically provide much-needed solutions to current global food and nutritional security challenges. In this review, we provide a bird’s eye view of the relevance of millets in global agro-ecosystems in the context of their nutritional and agronomic attributes. Furthermore, we share perspectives on the major areas of crop improvement programs worldwide and discuss major challenges confronting the same. Finally, we discourse on the scope of millets for wider acceptability and highlight major points at the interface of genetic intervention–crop management post-harvest practices worth considering to potentially facilitate robust millet-based nutritional and food security.
