I did some work on the Impact of Small Scale Irrigation Technologies on Poverty Alleviation among Peri-Urban and Urban Farmers, you can have a look at it.
Dear Ali, I have read following interesting article, and you also can have a look, if appropriate.

An important economic researcher in that area is Federico Aguilera Klink, from a ecological point of view. You can find someone in this link a in his Reserchgate perfil:
In the Canadian Prairies the land is divided into 160 ac parcels (= 1/4 Section = 0.5 mile x 0.5 mile). Farmers have a water allocation to draw from the groundwater or the river but do not pay for the water. The only cost is for the energy to pump the water.
The capital cost are as follows:
Travelling gun system: C$30,000
Centre Pivot system: C$ 60,000
Drip system: C$ 180,000
The most popular system is the centre pivot system accounting for >50%
Farmers also use side-roll and linear move systems which cost in the 20 to 30K range.
