How human activity can make water stress worse
- Abstraction
  - Removing water from rivers and ground water sources can cause issues that in some arid areas rainfall can never recharge these underground stores
  - The removal of fresh water from aquifers in coastal locations can lead to salt water incursion
- Dams
  - Trapped sediments in resovoirs reduces the floodplain fertility and the flow of nutrients from rivers into seas
- Fertilisers
  - Chemical fertilisers contaminate groundwater as well as river and water supplies. These add nutrients to the water leading to an increase in algae growth downstream
- Industrial waste
- Sewage Disposal
  - Sewage disposal in developing countries is expected to cause 135 million deaths by 2020
  - In the UK we add 1,400 million liters of sewage to our rivers daily although most of it has been treated
