    Climate change impact on human health
    (CABI, 2024) Singh, Samar; Chhatwal, Himani; Pandey, Ashutosh
    Variations in environmental conditions caused by natural or anthropogenic activities have been exhibiting their impacts on climate change in the form of heat waves, drought, acid rain, floods, and storms throughout the decades. The resulting climate change has perturbated the interrelated threats to the ecosystem. Climate change affects human health, causing mental illness, undernutrition, and cardiovascular, respiratory, and infectious diseases. This outcome is observed in terms of worldwide disturbance in social dynamics such as health status, socioeconomic status, and public health infrastructure. This chapter explores the adverse climate conditions and highlights footprints on human health. Strategies to reduce the catastrophic impact of climate change on humans have been discussed in the latter sections.

    Hotspots associated with climate change and food security risks
    (CABI, 2024) Chhatwal, Himani; Singh, Samar; Pandey, Ashutosh
    Climate change is an emerging problem, threatening nations at a global stage. Our knowledge about the impact of climate change on agriculture has grown over the past two decades, but recently, it has been found that its effects are even more deep-rooted. Anthropogenic and natural activities are increasing global temperatures at an alarming rate, affecting crop productivity. Extreme weather events will impact food supply, stability, and access. In the current times of increasing population, when wholesome food production is a global concern, climate change becomes an inevitable issue that no nation can escape from. This chapter highlights the major hotspots of the world which face an immediate threat from climate change. It also covers the perils of changing climate on the food production system and the adaptation strategies to overcome it. The need is to focus on developing immediate solutions to develop a sustainable food supply in the future.

    Genetics of plant organelles: Plastid and mitochondrial genomes
    (Springer Nature Publishing AG, 2022) Singh, Samar; Naik, Jogindra; Pandey, Ashutosh
    Plant organelles like chloroplasts and mitochondria are essential organelles serving critical functions like photosynthesis and respiration, respectively, in plants. While most of the processes and the components required by the functioning of these organelles are contributed by nuclear DNA, they have few of their own components encoded by their respective genome. Mitochondrial and chloroplast genomes give a real insight into the evolution of land plants, as evident by several studies. Few studies have successfully conducted gene transfer technology into these organelles’ genomes. Although extensive research on plant organelle genome is yet to be done, recent research has shown the probability of these organelles as a target of genome engineering. From targeting individual genes of their genome to incorporating new genes from other species, they hold promises to produce improved traits. Packaging of their genome, which varies significantly in various hierarchies of land and primitive plants, has also been studied in few plant species. This chapter summarizes the current studies and findings in the study of the organellar genome concerning their structure, organization, distribution, regulatory mechanism, and gene transfer technologies. This chapter provides an updated account of the evolution of these organelle genomes.
