What are the benefits of canals?
Canals are fed by rain water received by rivers, and the water is used for irrigation. Production of crops needing more water is also possible through canals. As compared to un-irrigated soils, higher productivity per hectare is also possible due to canals. The main advantage to canals is the ease of shipping goods.
What are the disadvantages of Canal?
1. Due to imbalance in distribution of canal water, a situation of scarcity somewhere and water logging in other areas is caused due to collection of water there. It makes the soil unproductive as harmful underground salts and alkalies come to the surface level due to water logging.
Are there negative impacts of the canal?
One of the negative environmental impacts the canal could have is leakage of saltwater into groundwater reservoirs, thereby contaminating them. As well, the canal itself could create a physical barrier for wildlife trying to move from one area to the other.
