Question 1
1. Each system, including tank, pipes, gutters and filters, cost US$195—equivalent to a month’s income for an average village family. Just over half the cost was provided by the community, in the form of materials and unskilled labour. Practical Action South Asia contributed the rest, including cement, transport and payment for the skilled labour.
The cost of rainwater harvesting systems was shared by local villagers and the local government.
Question 2
2. Several other organisations have begun their own projects using the same approach of Muthukandiya. The feasibility of introducing larger tanks is being investigated.
Other organisations had built tanks larger in size than the tanks built in Muthukandiya.
Question 3
3. ‘Global warming’ is another example of problematic terminology. Climatologists predict more drastic fluctuations in temperature and rainfall—not necessarily that every place will be warmer.
‘Global warming’ scientifically refers to greater fluctuations in temperature and rainfall rather than a universal temperature rise.
Question 4
4. Yet there are steps we can take to improve public understanding in all cases. The first would be to inculcate greater understanding and acceptance of indirect scientific evidence. The information from an unmanned space mission is no less legitimate than the information from one in which people are on board.
Public understanding and acceptance of indirect scientific evidence in all cases would lead to confusion.
Question 5
5. Human systems are better able to adapt to change than natural ecosystems because humans can see a problem coming and plan a response.
The natural world is less responsive to challenges than humans.
