04 May DELTA Model® version 1.3 launched
The coloured bar shows the global average availability of each nutrient. The error bars show the range in availability in different parts of the world (10th and 90th population percentiles based on country level averages). While there are only a couple of nutrients where global availability is below target, the level of variation results in many more nutrients of concern at a country level.
The latest version of the DELTA Model® is now available online. It features new insights into national and regional nutrient availability, as well as nutrient trade.
It’s common to talk about food trade between countries or regions, but less common to think about the movement of individual food nutrients around the world. For example, New Zealanders are probably very aware of our country’s exports of animal-sourced foods (like dairy and red meat), but likely haven’t thought about what this means in terms of the calcium or iron included in these exports.
DELTA 1.3 presents the domestic production of 29 food nutrients, the export and import dynamics of these nutrients, and how this measures up to meeting per capita per day nutrient targets for a country. It also presents how this availability differs in different parts of the world, showing the user the inequalities in access to different nutrients. The results are adjusted for waste, non-food uses and bioavailability in the same way as the rest of the DELTA calculations.
Another change is to the splash page first displayed to the user. This now features an outline of the global nutrition challenge that the world is facing, as well as a description of how the DELTA Model® was designed to contribute to our understanding of this complex challenge. Further additions and changes can be found in the release notes.
