Band 7+: The charts show the percentage of available water resources in Japan in 2000, 2010, and 2020. The table shows the percentage of annual water consumption in the country in those three years. Summarise the information by selecting and reporting the main features and make comparisons where relevant. Write at least 150 words.

The charts show how Japan’s water resources were distributed in 2000, 2010, and 2020, along with how much water people used during these years.

Seawater was the main source of water, but its share gradually decreased over time. Glaciers became a more significant source, while groundwater and rivers/lakes contributed relatively little. At the same time, water consumption steadily rose.

In 2000, most of Japan’s water about two-thirds came from seawater. Glaciers made up a smaller but still important portion, roughly one-fifth. Groundwate and rivers/lakes, on the other hand, played a much smaller role, together accounting for less than one-sixth. Over the years, the reliance on seawater dropped slightly but still made up over half by 2020. Meanwhile, glaciers became more important, rising to around a quarter of the total. Groundwater stayed steady at under a tenth, and rivers/lakes shrank to just a tiny fraction.

When it comes to water usage, people were using just over 60 gallons a year in 2000. This number grew steadily, increasing by about a fifth by 2010 and continuing to climb, reaching nearly 100 gallons in 2020.
