The maps on pages 76-77 indicates the amount of water available per person in each country.the maps don't show total amounts of the available frsh water each year.the map for the year 2025 is on population estimates for that year.

What factors might cause the changes in freshwater availibilty you see in the maps?
In places like India and Africa the population is increasing but the amount of fresh, clean water is not increasing so people must share the same amount of water. Climate changes may also reduce the amount of clean water available. Plus some sources of fresh water like wells are being polluted and now these sources are not available.

What concerns for the future can be drawn from the maps?
The maps show that freshwater is shrotening so that means that the price of frshwater will increase. It could also produce to less food production because many foods need freshwater to grow. In addition, health problems could arise because because people will turn to less safe water sources to survive.
