“…Vineyards' development, and ultimately fruit growth, depend on edaphoclimatic conditions and viticulture practices [15]. Accordingly, surface water drainage can be influenced by terrain morphology, namely since planar zones tend to accumulate this water and thus promoting its infiltration on soil [16]. The information attained from UAVs, specifically regarding drainage, suggests that attention must be given to water availability for this terrain, in order to assure the necessary uptake of nutrients from soils, since poorly drained or with high salt content soils, affects grape crop's capacity to thrive under such soil conditions [17].…”

In the context of an exponentially growing population and resource limitations, precision agriculture techniques can improve efficiency in the agricultural sector. This can be achieved by monitorization and quick detection of changes in crops, resulting in smart resource use, waste reduction and maximization of production. In a field located in Palmela (Portugal), three foliar sprays of ZnO and ZnSO4 were performed in Vitis vinifera variety Fernão Pires, for production of biofortified single-vine wine. Field characterization was performed with soil sampling and UAVs (with altimetric measurement sensors), synchronized by GPS. Vegetations indexes and characterization of drainage capacity and slopes were then interpolated with mineral content, monitored with X-ray Fluorescence analysis. Morphologically, the experimental parcel had a slight slope (maximum of 1.10 m) with irrigation and nutrient availability in soil requiring special attention (i.e., just one-third of the parcel had higher capacity to water drainage). NDVI values reflected better physiological values in the N–NE region. Zinc increases in leaves were directly proportional with the applied concentrations in vines sprayed with ZnSO4 and ZnO; the concentration of 60% (900 g ha−1) revealed a greater vigor. In conclusion, the use of smart farm techniques and their crossing with analytical procedures allows the characterization and monitoring of vines, and a higher potential for optimization of wine production.

“…Unfortunately, this is a more expensive approach and is readily washed away by rain 122 . Foliar applications of calcium applied to Rocha pear trees in which the leaves were treated with either Ca(NO 3 ) 2 or CaCl 2 showed an increase in calcium content in the fruit, both in the epidermis and the central region of the fruit 126 . Importantly, there was no toxicity to the plant and no significant change to the sensory acceptability of the fruit.…”

Calcium intake remains inadequate in many low‐ and middle‐income countries, especially in Africa and South Asia, where average intakes can be below 400 mg/day. Given the vital role of calcium in bone health, metabolism, and cell signaling, countries with low calcium intake may want to consider food‐based approaches to improve calcium consumption and bioavailability within their population. This is especially true for those with low calcium intake who would benefit the most, including pregnant women (by reducing the risk of preeclampsia) and children (by reducing calcium‐deficiency rickets). Specifically, some animal‐source foods that are naturally high in bioavailable calcium and plant foods that can contribute to calcium intake could be promoted either through policies or educational materials. Some food processing techniques can improve the calcium content in food or increase calcium bioavailability. Staple‐food fortification with calcium can also be a cost‐effective method to increase intake with minimal behavior change required. Lastly, biofortification is currently being investigated to improve calcium content, either through genetic screening and breeding of high‐calcium varieties or through the application of calcium‐rich fertilizers. These mechanisms can be used alone or in combination based on the local context to improve calcium intake within a population.

“…The production of biofortified crops enriched in macro-or micro-nutrients has been applied several years ago such as Ca (Pessoa et al 2021), Cu (Yusefi-Tanha et al 2020a), I (Budke et al 2020(Budke et al , 2021, Fe (Coelho et al 2021;Okwuonu et al 2021), Mg (Kumssa et al 2020), Se (Lessa et al 2020;Hossain et al 2021;Trippe III and Pilon-Smits 2021), Zn (Okwuonu et al 2021 andSilva et al 2021). Using some vitamins (Fitzpatrick and Chapman 2020;Jiang et al 2020;Tiozon et al 2021) and other essential compounds like carotenoids (Watkins andPogson 2020 andZheng et al 2020) and folate (Strobbe and Van Der Straeten 2017;De Lepeleire et al 2018;Viscardi et al 2020) for human health also have been applied in biofortification strategies.…”

Is Nano-Biofortification the Right Approach for Malnutrition in the Era of COVID-19 and Climate change?

H UMAN health may depend on the environment and its compartments, which may include climatic factors. These climatic factors and their changes might impact on human health particularly the outbreak of pandemics like COVID-19. The combined stress resulted from climate changes and COVID-19 could be noticed in several countries especially in the developing countries. Malnutrition is considered one of the most important problems in the developing countries in particular under the droughts, flooding, and other climatic events. Malnutrition was aggravated under COVID-19 outbreak in these countries due to the closure of borders between countries, the crisis of global trade, and the global food insecurity. The biofortification process is the sustainable solution to overcome malnutrition, which included very recently using nano-nutrients as called nano-biofortification. The approach of nanobiofortification is a promising tool in producing biofortified edible plants, otherwise this tool still needs more studies to answer the open questions like which nano-nutrients can be used in nano-biofortification? Which recommended doses and crops are considered suitable candidates?
