(i) In 2012, what was growing and harvesting forestry worth to the Irish economy? (ii) In which year did Ireland have the highest number of visitors to its forests? (iii) Which forestry sector hires more people? (iv) What was the total economic worth of forestry (growth and wood manufacturing) to Ireland?


Sustainable Exploitation of Soil


7. The table below shows two ways to manage and exploit soil sustainably. (i) In the spaces provided, add a third solution, and then explain what each solution is, how it works and where it is used. In the last row, suggest and discuss your own solution.


Exam Hint


Be mindful of the difference between the questions asked here. ‘What It Is’ is asking you to describe the type of soil management. ‘How It Works’ is asking how it benefits the soil. When choosing the third type of soil management, can you think of any practices not used in Ireland? They may be used in more extreme climates.
