DELTA FAQ’s

The DELTA Model® is a global food system mass balance that uses information about current food production to predict the nutrition available to the average global citizen both now and in the future.

The model lets the user adjust the production of different food groups, the degree of food waste, and the global population to see the impact of these changes on human nutrition. The most recent version also calculates the cropland area required for food production.

Future versions of the model will include estimates of the impacts of food system scenarios on total land use, greenhouse gas emissions, and other resource constraints.

Features of the DELTA Model®

The DELTA Model® has several attractive features that make the tool broadly applicable:

Scenario options contains high level scenario settings and enables the user to switch between predefined food system options.

Primary production contains the annual production of each of the food product groups in millions of tonnes.

Secondary modifiers contains a range of other model options for the user to select.

Food production information is taken from the UN Food and Agriculture Organisation (FAO) Food Balance Sheets and combined with food composition data from the United States Department of Agriculture (USDA) FoodData Central. The core of DELTA is a model that allows the user to modify food production from the FAO food balance sheets and view the impact on the nutrition available to the average global citizen.

The DELTA Model® has been developed to help people explore this challenge themselves by manipulating the major components of the food system to see the impact on the supply of key nutrients.

 

The Delta Model generates viable outcomes from complex initial scenarios.

FAQs

Why only nutrition?

The only aspect of sustainability outside of nutrition that is currently included in the DELTA Model® is cropland requirement. Future development of the model is focused on further inclusions.

What is the target for running a scenario?

The goal for any scenario of the global food system should be to meet the target intake for all nutrients in the DELTA Model®, shown as the black bar on the nutrient supply charts. The DELTA Model® assumes even distribution of food commodities among the global population. In reality, food is not evenly distributed globally. In addition, adverse events such as droughts or floods can affect food production and distribution. Therefore, to account for this, the nutrient supply per person per day should be slightly above the target intake.

What does food waste include?

Supply chain waste represents losses that occur from farmgate to retail. In-home waste is food waste that occurs in home by consumers. Inedible material in food used (e.g. inedible fruit and vegetable material skins) is not included in food waste; the DELTA Model® calculates this inedible portion separately. Any mass that does not leave the farm is not counted as food supply, so cereal stalks and husks that are left behind are not included as food waste.

What does food production include?

Food production in the DELTA Model® includes all biomass that leaves the world’s farms that enters the food system. Some of this will go to human consumption, while some will be used as animal feed or for other uses, and some will be wasted. Synthetic or non-food sources of nutrition (e.g. fermentation produced protein and mined minerals) are not included.

Does nutrient provision account for losses of bioavailability during cooking?

Does nutrient provision account for losses of bioavailability during cooking? No. The model assumes that all bioavailable nutrients in food consumed are in raw form. The reality is that food can be prepared and consumed in many different ways, affecting nutrient composition and bioavailability. However, the complexity of modelling this would bring a significant margin of error into the model. Therefore, the DELTA Model® assumes that all bioavailable nutrients in the raw commodity end up in the food consumed.

Does the model run optimisations to generate one right answer?

The purpose of the DELTA Model® is to not be constrained to one perfect answer, but rather to generate scenarios about possible food production scenarios, in order to generate informed discussion and expand thinking. As such, the model does not calculate one right answer.

Are environmental footprints included in the DELTA Model®?

As of version 2.0, cropland use is included in the DELTA Model® as the first aspect of environmental sustainability to be modelled. Environmental sustainability is a key part of a sustainable food system but a broad quality. As such, resource footprints (greenhouse gas, total land and water) should be considered by the user when evaluating future possible food systems. Other aspects of environmental sustainability are targets for future model development.

Can input data be selected by country?

As of version 1.3, The DELTA Model® allows the user to investigate national nutrient dynamics in 2015 under the Helpful tab. However, there is no functionality for DELTA Model® scenarios at the national level.

How is transport/supply chain to get food from production to mouth factored?

The DELTA Model® uses the FAO food balance sheets, which encompass the entire supply chain from farm gate to retail, capturing losses and distribution into different uses. Since environmental footprints are not yet included in the model due to data issues, this aspect of transport and supply chain is not yet included in the model. Indeed, the complexity of the global supply chain is one of the main reasons why many of the environmental impacts of a DELTA Model® scenario are not yet estimated in the model.

Does the model address the uneven distribution of food and nutrients globally?

As of version 1.3, the DELTA Model® displays the inequitable distribution of nutrients between different countries in 2015. However, there is no scope to use DELTA Model® scenarios to investigate this distribution in the future. The focus of the DELTA Model® is on the global food production required to meet global nutrient requirements. When running various scenarios in the DELTA Model®, a slight over-production of all nutrients should be the target, to act as a buffer to account for the uneven distribution of food and nutrients globally.

What is the difference between global demand and nutrition required?

Demand is the quantity of food global consumers are willing and able to purchase. Nutrition required is based on the target intakes of each nutrient for the global population. For example, while demand may be increasing for protein, the DELTA Model® shows that there is already sufficient protein to meet global nutrient requirements.

What is the difference between reference diet adjustment and bioavailability adjustment?

The reference diet selection has the options: base, vegetarian and vegan. Selecting the vegetarian or vegan diets increases the target intake values for iron and zinc, to account for lower bioavailability of these minerals in high plant diets. Because there is insufficient data on the bioavailability of these nutrients in all foods, the target intake increases to account for the fact that a higher iron intake is recommended to meet requirements in a vegan or vegetarian diet compared to an omnivorous diet.

Contrastingly, there is sufficient scientific data on the bioavailability of essential amino acids from different protein sources. The DELTA Model® adjusts for this bioavailability unless the relevant checkbox is selected.

Does the DELTA Model® dictate an individual diet?

No. The purpose of the DELTA Model® is to explore the ability of different food production scenarios to provide the bioavailable nutrients needed to adequately feed the global population. It does not try to provide the answer to sustainable diets for individuals.

How were the default scenarios created?

The default scenarios (e.g. 2030 Vegetarian, 2030 Scale-up Current) are rough estimates of what the given scenario might look like in terms of food production. These are intended as starting points for the user to explore from, rather than predictions based on food system forecasts. For example, the 2030 Vegetarian scenario has zero meat and seafood production and uses the 2030 forecast population. This represents a possible food system scenario that the user can then adjust to explore nutritional outcomes.

How do I use the Nutrient Density tool to identify which foods to build up in the food system?

To build an efficient food system it is useful to start with nutrient-rich foods, particularly those rich in limiting nutrients. The nutrient density chart is a tool to discover which foods are rich in specific nutrients. Production of these foods can be increased in a scenario to ensure nutrient requirements are met. By navigating to ‘Helpful’ and selecting ‘Nutrient Density’, two charts will appear side by side. The nutrient density chart is on the left, and a chart showing food use of the item is on the right. The purpose of the food usage chart is to help identify which foods are realistically able to contribute to nutrient supply. Foods that have high nutrient density, and also relatively high food use have good practical potential to contribute to global provision of that nutrient. The target nutrient can be changed to view the nutrient of interest using the drop-down box. This nutrient can then be constrained against a number of different parameters. Mass is the default dietary constraint, but this can be changed depending on what the limiting factor is in the scenario.

Are synthetic nutrients included in the DELTA Model® ?

No. Synthetic nutrients, such as fermentation produced protein or mined minerals, are not included. To include synthetic nutrients, accurate data is required on their production. For example, accurate data would be required on the biomass feed required to obtain a certain amount of protein via fermentation, which is not yet available.

What does the Nutrient Contribution Score mean?

The Nutrition Contribution Score is a metric to give a sense of how valuable each food item is in terms of its nutritional contribution to the global food system. The DELTA Model® calculates this score for each food item by taking the proportion of each nutrient (e.g. Calcium, Vitamin A) supplied by the food item (e.g. Apples, Bananas), and then summing these for all nutrients. Energy and carbohydrates are excluded from the calculation, as a high contribution to these values is not necessarily beneficial to the global population.

Constraints of the SNi DELTA Model®

Vitamin D and iodine
Non-essential amino acids include: alanine, arginine, asparagine, aspartic acid, cysteine, glutamic acid, glutamine, glycine, proline, serine, and tyrosine. These have not been included in the DELTA Model® as the internal processes the nutrients are involved in are challenging to account for accurately, and these nutrients can also be synthesised from essential amino acids. Essential acids isoleucine and valine are also not present in the DELTA Model® currently as they are rarely the limiting amino acid in the human diet. Inclusion of these nutrients in the model is being considered for future versions.

Materiality
The DELTA Model® provides scenarios that indicate directional movement to determine any adverse outcomes in food supply and nutrient availability from various scenarios. This is not to say that the outcomes of such a scenario (e.g. no meat) will most certainly result in the simulated nutrient deficiencies, rather it alludes to likely outcomes of changes in production. Changes in future food production will be broad and nuanced, and it is imperative to ensure the direction that such changes shift global nutrient availability is adequate to feed our growing population.

Microbiome
A healthy human intestinal microbiome provides numerous services, such as supporting absorption of nutrients and acting as a protection against infection. An unhealthy microbiome can be linked to poor health. Research insight has suggested that although a correlative relationship has been found between microbiomes and disease, the underlying processes that would determine a causal relationship are uncertain. As such, the role of the intestinal microbiome in nutrition is beyond the scope of the DELTA Model®.

Global averaging of nutrient availability
DELTA assumes an equal distribution of food globally and produces an average nutrient availability for the global population. This does not capture the realistic distribution of food that is inequitable across the world. This is because the DELTA Model® considers nutrient adequacy at a global scale and provides insight on various food system scenarios and the capability to produce nutrition for all. Both the individual and the global perspectives, and thus both modelling approaches, are necessary when considering the aptitude of the food system. DELTA does include historic information of on the distribution of nutrients at a country level, which provides come insight into the range of availability. However, there are too many variables to project this variation onto future scenarios, and insufficient data to look at the variation in intake or availability within countries.

Demand versus requirement
DELTA considers only nutrient requirements. Nutrient demand, where the specific nutrients and amounts are determined by consumers, is quite different and is not captured by DELTA Model®.

Bioavailability
The current version of the model contains good data for protein and amino acid bioavailability. For iron and zinc, the availability of data for individual food items is not as great, therefore bioavailability is captured by changing nutrient requirement values. Due to insufficient bioavailability data for all other nutrients, no consideration of bioavailability is made for these.

Nutrient absorption
Nutrient absorption is dependent on the meals and food combinations people make in their diet. Individual diets are beyond scope of DELTA, and thus meal effects are not captured.

Nutrient targets
The strength of the model’s nutrient requirement estimates are dependent on the EFSA data source. For some nutrients, limited data is available on human requirements, whereas for others there is sufficient data for all age and gender groups to set upper and lower bounds on intake, as well as target intakes.

FAO data
The FAO data that informs the model has limitations. Some countries are missing data, and the quality of data reported varies between countries. Moreover, inhome waste estimates are at a regional and food group level. Unfortunately, this data is the best currently available and is sufficient for directional conclusions on future changes to the food system.

Resolution
Currently, food items are grouped into 15 food groups for ease of use by a broad audience. This means that any increase in the total production of a food group causes a proportional increase in the production of each food item within it, following the distribution in the baseline data set. This increase is carried through all model calculations: waste, other uses, and the available nutrients. Future versions of the model may allow for user input at a higher resolution.
