Answer 1

Hint:
> The artificial process of applying water to the crops in order to fulfil their water requirements is known as Irrigation.
> The different sources of irrigation are wells, ponds, lakes, canals, tube-wells, and even dams.

Complete answer:
A variety of methods were used for irrigation. In some areas, wells were dug whereas in other places huge tanks were constructed to collect rainwater. Irrigation works require planning and organizing of labour and resources, maintaining these works and deciding on how water is to be shared among the people living in villages who take an active interest in these activities.

The kind of irrigation works that were created in the Tamil region are as follows: in many areas, wells were dug and tanks were built for storage of rainwater, in the delta region, embankments were built in to prevent flooding, canals were built to carry water to the fields, sluice-gates were built that regulate the outflow of water from a tank into the channels that irrigated the fields.

The major source of irrigation in Tamil Nadu is canals, as the system tanks get the supply of water from permanent storage like reservoirs, dams, etc. Canal irrigation was responsible for 27.4% of the net area irrigated by all sources in the state.

Note:
> Irrigation is very important due to the reasons such as:
> Low rainfall can lead to drought and famine, so irrigation can help in increasing productivity. The output and yield levels can also be stabilized through it. It also helps in increasing the availability of water.
> It is also very important to maintain the irrigation at optimum because even over-irrigation can spoil the crop production. Excessive water can cause waterlogging, hinder seed germination, increase the concentration of salt and can cause uprooting because roots can’t withstand standing water.
