There are 3-line graphs compare three kinds of wheat’s export volume of different countries, namely Australia, Canada, and the European Community, over a five-year period between 1985 and 1990. It is measured in millions of tonnes. As an overall trend, the export quantity in Australia decreased, while wheat exports of the European Community increased, and the figure of Canada had the highest fluctuated over the given period.
Look at the details, Australia exported exactly 15 million tonnes in 1985, then it rose slightly by about 2 million tonnes before declining continuously over the next four years. In 1990, The amount of wheat exported to Australia was around 11 million tonnes, and it was the lowest.
European Community wheat exports started at about 17 million tonnes in 1985, then it reduced gradually to less than 15 million tonnes in 1986. The figure rose slowly and stayed constant in the following two years. After that, the wheat export in European Community climbed dramatically and reached a peak of over 20 million tonnes in 1990.
The wheat export of Canada was the highest of the three countries, with about nearly 20 million tonnes. After a slow decline in 1986, the volume soared extremely and reached the highest point at exactly 25 million tonnes. Then, It dropped significantly by about 11 million tonnes from 25 million tonnes to nearly 14 million tonnes.
In summary, the rankings of Canada and the European Community were swapped first and second ranking with each other. On the other hand, Australia remained the lowest ranking of the three given nations.
