Abstract: Climatic changes will probably pose a threat to global food and nutrition security, especially in arid and semi-arid regions. In correlative reports of the available literatures, the bioavailability of micronutrients in crops was likely to have important and poorly understanding with climate change, which was of particular concern in soil improvement in drylands. The objective of this paper was to stimulate debate on a theme that bioavailability of micronutrients in foodstuff and food security had been either ignored or avoided in future research for its response to climatic change in semiarid area. In addition, there was a fairly good understanding of authors attempts to highlight potential consequences from experimental studies within process-based patterns of bioavailability of micronutrients in crops that should include interactions between climate and micronutrients accumulation. Furthermore, the authors gave some advices about prediction the bioavailability of micronutrients in crops or drylands soil improvement responses to future global climate change in arid and semi-arid area.

Key words:  climatic change, micronutrients, food security, semi-arid area
