TWO MAPS CLEARLY ... PAST 10 YEARS.
Why did you capitalize this sentence? This should be typed using regular fonts. Did you mean to use this as a title? That is not required in any IELTS writing task. next time, write naturally.
Your paragraphs need to be uniform in length. Anywhere from 3-5 sentences (maximum). Describe the first 5 years in paragraph 2, then the most recent 5 years in paragraph 3. As this is a report essay instead of an opinion presentation, you need not present a summary at the end. That is a task 2 requirement.
