Project Motivations

In recent decades, humans step into the gold time of human history. We have seen rising internet technology, growing digital society, and updating infrastructure. But if we pull back our sights to real daily life and onto the table, what is the change? For our team members(Chinese after the '90s), more meat. Today we can enjoy meat in different types of situations and have our own, very personal preferences. From our first thought, more meat consumption seems common for the whole world.

Brazil, Russia, India, China, and South Africa – the BRICS – are five big developing countries that are setting out from different starting points. They may not end up with the food consumption patterns of the industrialized West but it is undeniable that they together account for 40% of the world's population. The data shows that between 2003 and 2012, their meat consumption rose by 6.3 percent a year and it is expected to rise by another 2.5 percent a year between 2013 and 2022. Also, the demand for meat in the developed world has also peaked.

But will this trend continue(meat consumption grows), until when everyone in the world can enjoy as much meat as they wish? Maybe not.

OECD‑FAO Agricultural Outlook 2019‑2028, page 176

The above figure just plotted the meat consumption per capita, both actual recent data and projected data. Although FAO considered many factors to forecast future meat consumption, the interesting thing is that future meat consumption per capita may not exceed today. Actually, this cannot be fully explained by reason like the healthy diet style with balanced food types. Because in regions such as Africa and Asia, people still eat meat at a low level.

Since meat consumption will not grow steadily in all countries, the following question is where does it grow?

Motivated by this question and hoping to explain it, our team wishes to investigate all about the meat market, from production, consumption, to global trade.

Reviews on past work

1. Meat Altas

A highly recommended work is Meat Altas(Der Fleischatlas in German)[1], a publication by the Heinrich Boell Foundation - a German environmental NGO - and Friends of the Earth Europe. Consisting of 27 short essays by different authors, the report aims to inform consumers about the impact of meat consumption on global poverty, climate change, animal welfare, biodiversity, and the migration of workers.

The book cover of Meat Altas

The book shows a full image via small stories with internal links. In the report, charts are attractive, giving insights to normal consumers that they hardly see in the food package.

Though inspired by the authors' work and goal, we have to point out two weaknesses from the view of data analysts:

  • Most charts are in the same type of the above graph. They are successful in terms of story-telling visualization. However, some elements like the grid-line, background-color, and extended x-axis appear redundant, while the distinguishment between the recent trend and the future forecast is missing.
  • All conclusions are drawn by descriptive statistics and most of them are only qualitative. Surely we can test a conclusion to make it more convincing. More importantly, we can try to apply the time series analysis on meat production and consumption. If possible, a mathematical model can be built to conduct a sensitivity analysis and see how a change in the meat consumption amount will affect our world.
  • Moreover, since all short essays are from different authors, the use of data and graph lacks internal linkage. For example, one essay is “Disquiet in the Developed World”, and the next one is “Half A Billion New Middle-Class Consumer from Rio to Shanghai”, and two authors are sharing their own perspectives, which is not bad but only gives viewers a piece of jigsaw instead of a whole picture.

2. Resourcetrade.earth

A snap shot of sourecetrade.earth

Resourcetrade.earth has been developed by Chatham House to enable users to explore the fast-evolving dynamics of international trade in natural resources, the sustainability implications of such trade, and the related interdependencies that emerge between importing and exporting countries and regions. [2]

The visualization of resource trade achieves a remarkable balance of beauty and function. The layout of graphs, setting of drop-list, and combination of various graph types are all worth learning.

The only weakness is that this website only displays data about international trade. If the viewer does not have some common senses, then she/he will make a wrong judgment. For example, when you select “Agricultural Products” as the commodity and then select 2017 as the year, the trade flow plot shows the top 5 trade where China is the exporter for the top two. A viewer without any knowledge will think China is a major exporter worldwide, which is not correct. The truth is that under the “One Country, Two Systems” policy design, mainland China is supporting its two Special Administration Regions. Mainland China is HK’s most important food source, especially for fresh food. 94% of fresh pork, 100% of fresh beef, 92% of vegetables, and 66% of eggs in Hong Kong come from the Mainland.[3]

Data Resources

1. Meat worldwide trade dataset (link: https://resourcetrade.earth/about)

The meat trade data used in this project is collected and manipulated by website resourcetrade.earth (https://resourcetrade.earth/about#section-16). The original data is from Chatham House Resource Trade Database (CHRTD) which is a repository of bilateral trade in natural resources between more than 200 countries and territories. The database includes the monetary values and masses of trade in over 1,350 different types of natural resources and resource products, including agricultural, fishery and forestry products, fossil fuels, metals and other minerals, and pearls and gemstones. It contains raw materials, intermediate products, and by-products. In this project we just focus on the meat trade. This dataset covers the meat bilateral trade between nearly 250 countries and territories from 2001 to 2018, and there are 220194 rows of data.

Variable Description
Exporter information Provides the information about the exporter country, which includes M.49 number, ISO3 code, country name and the region belongs to.
Importer information Provides the information about the importer country, which includes M.49 number, ISO3 code, country name and the region belongs to.
Resourse The categories of meat including beef, pork, poultry, sheep meat and meat of other animals.
Year The year of the trades (from 2001 to 2018).
Value Monetary value of trade amount in 1000 USD.

2. Meat consumption and production dataset

(link for consumption data: https://data.oecd.org/agroutput/meat-consumption.htm link for production data: http://www.fao.org/faostat/en/#data/QL )

The data about meat consumption is from OECD(https://data.oecd.org/agroutput/meat-consumption.htm). This indicator is presented for beef and veal, pig, poultry, and sheep. Meat consumption is measured in thousand tonnes of carcass weight (except for poultry expressed as ready to cook weight) and in kilograms of retail weight per capita. Carcass weight to retail weight conversion factors are: 0.7 for beef and veal, 0.78 for pigmeat, and 0.88 for both sheep meat and poultry meat. The meat production data is from FAO(http://www.fao.org/faostat/en/#data/QL). From this dataset, we just select the production of beef, pork, poultry and sheep from 2001 to 2018. Via combining these two dataset together, we get the final meat consumption and production data which contains 5040 rows of data.

Variable Description
Country information Provides the information about the countries, which includes ISO3 code, country name and the continent belongs to.
Item The categories of meat including beef, pork, poultry and sheep meat.
Year The year of the trades (from 2001 to 2018).
Unit Two units of consumption and production amount, THND_TONNE(thousand tonnes) and KG_CAP(kilogram per capita).
Consumption The amount of meat consumed in tonnes(1000 kilograms).
Production The amount of meat produced in tonnes(1000 kilograms).

Methodology

  • Explorative data analysis: To get an outlook of datasets, we will visualize them and give key points before we answer focus questions. Basically, our visualization will include:
   1. The bar chart of global meat production/consumption/import/export, by country, year and meat type
   2. The international trade network of meat, by year and meat-type.
  • Network analysis: Some countries show apparent disbalance of the meat, like a high amount of production as well as a low amount of consumption, these countries function as a global meat supplier. Since meat production always requires time and infrastructure input, the main meat supplying countries may grow production and occupy global market share. So except for the local supply-demand relationship, we will analyze the international meat trade network and locate "hubs in a network".
  • Time series analysis: Since our focus question is related to future meat consumption, and every dataset is time-related, it is natural to conduct basic time-series analysis and see the pattern of meat-related values. And we would like to explore the production/consumption/import/export of each country and discuss characteristics like below(if any):
   1. Trend. If there is a trend in meat consumption, then it will quickly lead to a quick answer to whether we will have more meat or not.
   2. No Model!. Due to the lack of consumption data before 2000, we will have less than 20 time-points(yearly), which is not enough for a solid model like ARIMA.
The design framework of project

Story Board in Shiny

Scratch Description
Consumption & Production Explorer
The left is a scatter plot of countries with production amount at x-axis and consumption amount at the y-axis. Each scatter is colored based on country names and has the hover-info showing country name, production amount and consumption amount. The function of this scatter plot is to show viewers each country’s production and consumption amount over the years.
Global Meat Trade Explorer
Each node in the map is a country, and each edge is a yearly summarized trade between this country and the other country. The size, color of a node or an edge has no special meaning. The function of this page is to show the meat trade flow of a country each year. After the country, year, and meat type are selected, the below two maps show the import flows into, and export flows from this country. Generally, the more exporters a country has, the more likely it will increase its production in order to meet the demand and occupy more market share. Meanwhile, the more importers a country has, the wealthier it should be because the international transfer makes flesh meat pricier.
Network Explorer
Each node in this network is a country, and each edge is a yearly summarized trade between this country and the other country. Notice here all nodes are intentionally positioned by their actual coordinates. The color of each node and edge is corresponding to its region and the size is corresponding to the trade amount. The function of this network is to help viewers to find centers of the trade network and answer whether their focus country in the last page is one of those centers.
Trend Explorer
There are two series of scatters and smooth lines – production and consumption, with two colors to distinguish from each other. Since sometimes the trend is significant but unrecognizable to eyes if there is such a huge scale gap between two series that they are compressed into horizontal lines, a simple method like ordinary least square (OLS) regression is required to test the trend.
