Projected future distribution of date palm and its potential use in alleviating micronutrient deficiency

At the global level, maize is the third most important crop on the basis of harvested area. Given its importance, an assessment of the variation in regional climatic suitability under climate change is critical. CliMond 10′ data were used to model the potential current and future climate distribution of maize at the global level using the CLIMEX distribution model with climate data from two general circulation models, CSIRO-Mk3.0 and MIROC-H, assuming an A2 emissions scenario for 2050 and 2100. The change in area under future climate was analysed at continental level and for major maize-producing countries of the world. Regions between the tropics of Cancer and Capricorn indicate the highest loss of climatic suitability, contrary to poleward regions that exhibit an increase of suitability. South America shows the highest loss of climatic suitability, followed by Africa and Oceania. Asia, Europe and North America exhibit an increase in climatic suitability. This study indicates that globally, large areas that are currently suitable for maize cultivation will suffer from heat and dry stresses that may constrain production. For the first time, a model was applied worldwide, allowing for a better understanding of areas that are suitable and that may remain suitable for maize.

“…Studies of climate effects on pests and host species have advanced significantly in recent years and attained greater relevance, in terms of impact on distribution, physiology, phenology, genetics and behaviors of many invasive species [ 8 ]. It is predicted that climate change will have a great impact on agricultural crops such as date palm [ 9 ], maize [ 10 ], wheat and cotton [ 11 ], rice [ 12 ], as well as insect populations, both in natural ecosystems and agroecosystems [ 13 ].…”

The whitefly, Bemisia tabaci, is a major threat to tomato Solanum lycopersicum and ranks as one of the world’s 100 most invasive pests. This is the first study of B. tabaci (Biotype B and Q) global distribution, focusing on risk levels of this invasive pest, in areas projected to be suitable for open field S. lycopersicum cultivation under climate change. This study aims to identify levels of risk of invasive B. tabaci for areas of suitability for open field S. lycopersicum cultivation for the present, 2050 and 2070 using MaxEnt and the Global Climate Model, HadGEM2_ES under RCP45. Our results show that 5% of areas optimal for open field S. lycopersicum cultivation are currently at high risk of B. tabaci. Among the optimal areas for S. lycopersicum, the projections for 2050 compared to the current time showed an extension of 180% in areas under high risk, and a shortening of 67 and 27% in areas under medium and low risk of B. tabaci, respectively, while projections for 2070 showed an extension of 164, and a shortening of 49 and 64% under high, medium and low risk, respectively. The basis of these projections is that predicted temperature increases could affect the pest, which has great adaptability to different climate conditions, but could also impose limitations on the growth of S. lycopersicum. These results may be used in designing strategies to prevent the introduction and establishment of B. tabaci for open-field tomato crops, and assist the implementation of pest management programs.

“…The date palm ( Phoenix Dactylifera.L ) is one of the oldest popular fruit trees in many countries from arid and semi‐arid regions of the world, due to its nutritional, health, and low economic value (Shabani et al, ). The date palm is mainly cultivated in the Middle East and North Africa, with an annual world production of 7.19 million tonnes which has increased considerably during the last 30 years (FAOSTAT, ).…”

This study assessed the total polyphenol, total flavonoid, total flavonols, and condensed tannins contents were also monitored and their antioxidant properties in vitro were investigated using 2,2‐diphenyl‐1‐picrylhydrazyl radical cation, 2,2′‐azino‐bis (3‐ethylbenzothiazoline‐6‐sulfonic acid), ferric reducing antioxidant power, and β‐carotene‐linoleic acid bleaching assay for second‐grade dates (Phoenix dactylifera L.), from 10 Tunisian cultivars. The results prove that the methanolic extracts of date fruits are a rich source of phenolic compounds. In addition, a positive linear correlation (p<0.05) between the phenolic compounds and antioxidant activity was found. The major phenolic compounds identified and quantified by LC‐ESI‐MS were the trans‐ferulic and syringic acids for the majority of cultivars. In this way, these results contribute to enhancing the value of the date fruits might be more widely used by both fresh consumers and food industry as a source of natural antioxidants in the diet or as natural food additives in benefit of human health. Practical applications It is known the benefits of phytochemical compounds and antioxidant activity in the nutrition and the health of human. These chemicals offer protection to many chronic diseases such as diabetes, cancer, heart disease, and Alzheimer's. For that, it is indispensable to determine the richness of our alimentation in these elements. This study aims to characterize the photochemical ingredients and antioxidant activity of 10 varieties of common dates (Phoenix dactylifera L.) to valorize them in food industry or in pharmaceutical industry as bioactive source for human.
