Harvesting
Homework: Chapter 5 – Development issues and water
Q3a)
Advantages
Disadvantages
The nets and poles are relatively cheap to buy.
Repairs are essential. Nets are easily torn in the wind.
Repairs are easy to make and require little training.
Ground water is contaminated.
Fog harvesting technology does not need any electrical energy.
Many rural areas do not have a piped supply from a reservoir.
It is not foggy every day.
Some of the foggiest sites are some distance from rural communities.
It is not foggy every day.
b) Fog harvesting may be considered to be an appropriate technology for a poor rural community because it is cheap to install and maintain. Also, repairs can be fixed easily by little experienced people. The main advantage of the project is that the technology does not require any electrical energy which means it is environmentally healthy and the people or the government do not have to pay any money to run the technology. The technology can be created with little money as well which means the LEDC government do not have to spend lots of money to create the fog harvesting.
Q4) The fog harvesting systems in Chungungo has been a quite success because it provided at least clean water to people who did not have access to it for a long period of time. However, some people in Chungungo have complained that the water project didn’t go successful because it was chaotic and disorganised from the start and all the residents agreed that the rapid population growth in Chungungo, from 300-900 people about in 10 years, required more water than the fog harvesting provided water.
The fog harvesting System in Tshanowa also has been a major success because it provided clean water for many people who did not have access to it for a long period of time. The harvesting fog collected a minimum of 4 litres per meter squared, with a maxim yield exceeding 3800 litres a day. Although these yields were not high, but they did provide clean water to people
