How is this figure likely to change in the next 50 years?
Lesson objectives: To examine the factors that influence access to safe water
Some might argue that access to safe water is the most important factor affecting development.
What do you think?
• There are currently more than 1000 million people in the world that lack access to an easily accessible and safe water source, such as a connection to water mains or a protected well.
• Instead, water access is limited or available through unprotected sources

• By 2015, halve the proportion of people without sustainable access to safe drinking water and basic sanitation
• Roughly 88% of India’s available freshwater is used for agriculture. Agriculture contributes around 16% of India’s GDP and employs roughly half the countries workforce. However, the insufficient treatment of human waste and the use of pesticides have polluted many rural water supplies. Rural regions in India are often low-income areas with low standards of education, which can restrict the use and maintenance of sophisticated water treatment technologies.
In 1999, Coca-Cola company, established a plant in Plachimada, in the Palakkad district of Kerala, southern India.
Two years after production began local communities complained that water pollution and extreme water shortages were endangering their lives.
• Residents protested that their wells had dried up because of the over exploitation of groundwater resources by the Coca-cola plant.
• They now had to walk nearly five kilometres twice a day to fetch water.
• They also argued that water was undrinkable and when used for bathing the water burned their eyes.

• Create a mind map of political, social, economic and environmental factors that influence Kerala's access to safe drinking water
• Remember to include FACTS and FIGURES, key PLAYERS, KEY TERMS
• What could be the social, economic and environmental consequences of the issue?
1. Identify 3 reasons why the region of Tamil Nadu suffers from physical water scarcity
2. Describe methods used to improve access to safe drinking water
3. Explain why this may be a sustainable source of potable water
4. Evaluate the use of this method to achieve sustainable water
How can access to safe water be improved?
• Small scale? • Large scale?
