Over the years, the canal irrigation system of Pakistan has witnessed many paradigm shifts in the context of advancement and effectiveness. From the olden practices of the conventional well system to the modern approaches of perennial canals and tubewells, the canal irrigation system of Pakistan has beheld some very significant changes.

In the initial years of the adoption of the canal irrigation system, there were various ways to irrigate the fields such as shaduf, charsa, persian wheel and karez. In Shaduf, it is a balancing act where a bucket is attached to one side while on the other side the weight of the bucket is balanced by a tantamount weight. Shaduf is used to irrigate a small piece of land. Coming to Charsa, it is characterized by animal power, which is incorporated to draw the water from the well. Then comes the persian wheel which is used to irrigate vast expanses of land and is a system of perpetual water supply. Coming towards the next one, it's the karez, which is a horizontal canal, which is built underground in the foothills. This approach is primarily used to prevent the evaporation rate as it is built underground.

Irrigation is a very significant part of cultivating crops and for an agro-based economy like Pakistan, it is immensely critical to the economic development of the country. In this age of globalization where competition is increasing, there are always new ways coming up for cost- reduction and time-reduction, both of which are priceless commodities in the contemporary state of affairs. Same goes for the irrigation system in Pakistan that has adapted to the demands of time and has gone through a series of modern changes. The modern means of irrigation in Pakistan are inclusive of tubewells, tankers and perennial canals. Regarding tubewells, they have the power to irrigate farms spread over an expanse of over a thousand hectares, raising water from a depth of about 300 feet that estimates to around 92 metres. Next come the tankers, which are configured to collect water from various ponds and lakes and provides to households and fields in the state of an emergency. Because this method is very expensive, it is not usually used for irrigation. Then follow the perennial canals, which irrigate a large area of lands and are linked to dams and barrages in order to continue their 'perennial' supply of water throughout the year.
