    Matters of the desert: A perspective on achieving food and nutrition security through plants of the (semi) arid regions
    (Elsevier, 2023-12) Deepa, P.R.; Sharma, Pankaj Kumar; Joshi, Mukul
    The semi- and arid agro-climatic zones of India harbor numerous plants, many occurring as wild and neglected inhabitants of the desert landscape, that bear edible fruits. They are capable of growing in extreme temperatures, on marginal lands and water-scarce conditions. These also represent sustainable food sources for the future. The benefits that they confer to the ecosystems and communities can be manifold: (a) as influencers of agricultural productivity for other crops (like cereals) in agroforestry systems; (b) as balanced functional foods by way of providing high quality protein, macro- and micronutrients to target protein-calorie malnutrition; (c) as sources of antioxidants, nutraceuticals and bioactive leads to target the ever-increasing burden of non-communicable diseases like obesity, diabetes and cardiovascular disorders. A few representative examples of the promising desert plants include: Prosopis cineraria, Acacia senegal, Cyamopsis tetragonoloba (cluster bean), Capparis decidua, Ziziphus mauritiana (Indian jujube), Cordia dichotoma, Leptadenia pyrotechnica, Calligonum polygonoides, and millets. Even though the potential of such plants has been recognized by food and agricultural scientists, research gaps like low yield, disease vulnerability, presence of anti-nutrients, unavailable genomic sequence information, exclusion from the formal food value chain, and poor marketing strategies, prevent the realization of their full potential. The current perspective looks at the promise afforded by underutilized plants of the Indian desert regions in ensuring food and nutrition security as well as the possibility of developing value-added agri-food products from them. The complementary role that food processing technologies can play in achieving the desired goals would also be highlighted so as to transform the desert plants from traditional to ‘climate-smart’ future foods.

    ML-based technologies in sustainable agro-food production and beyond: Tapping the (semi) arid landscape for bioactives-based product development
    (Elsevier, 2024-08) Joshi, Mukul; Deepa, P.R.; Sharma, Pankaj Kumar; Mahapatra, Tanmaya
    The current era of rapid climate change necessitates greater emphasis on wild, often underutilized yet sturdy, edible plants that are capable of growing in harsh arid lands. When compared to more popular crops like rice, these are often of traditional significance and more region-specific; but needing less chemical fertilizers, pesticides and irrigation water, they can not only provide food and nutrition in a sustainable manner but also medicinally valuable compounds (nutraceuticals) to target various communicable and non-communicable diseases. These bioactive metabolites could also serve as markers for in-process quality control of herbal formulations and as metabolic biomarkers. Of late, a few of the common food crops across the world have benefited from the use of technological interventions, employing various Internet of Things (IoT) devices and sensors to collect data on the farm and conduct agro-food specific analytics. Machine Learning (ML) and deep learning (DL) have found application in numerous facets of agriculture, particularly in tasks such as yield prediction, disease detection, weed detection, crop recognition, and assessing crop quality at pre-harvest, harvest, and post-harvest stages. ML technology also has shown potential to be effectively employed at various stages of bioactives discovery, encompassing target identification, compound screening, lead discovery, as well as pre-clinical and clinical development phases. However, the usage of these modern technologies has been less explored in the desert plants of the world. The current article reviews a few available examples and highlights the potential of employing ML and DL technologies in edible plants of the world, with a focus on sustainable desert flora, for achievement of multidisciplinary objectives, that is, agro-food production, food safety and bioactives discovery.
