Worked Solution & Example Answer:Irrigation (i) State what is meant by the term irrigation - Junior Cycle Geography - Question 4B - 2019
Step 1
State what is meant by the term irrigation.
Answer
Irrigation is the process of supplying water to crops and land to promote growth, typically through artificial means. This may involve a system of channels, pipes, or sprinklers used to deliver water from a source, such as a river or reservoir, to agricultural fields, especially in areas with insufficient rainfall.
Step 2
Describe one positive effect and one negative effect of any irrigation scheme that you have studied.
Answer
A positive effect of an irrigation scheme, such as the Aswan High Dam in Egypt, is that it has significantly increased agricultural productivity by ensuring a steady water supply, allowing for the cultivation of crops in otherwise arid regions. This has helped improve food security and economic stability in the area.
Conversely, a negative effect of the Aswan High Dam is the environmental impact it has caused, including the disruption of local ecosystems and sediment flow. This has led to issues such as salinization of soil and decreased fertility over time, adversely affecting long-term agricultural yields.
