Give a geographical reason for each of the following:

(i) Many farmers in India still use wells.

(ii) There is very little recharge of groundwater.

(iii) Tubewells are important in Punjab.

(i) Many farmers in India still use wells because wells can be dug at a very low cost and the oxen which are kept for ploughing the land can be utilised for drawing water from the well.

(ii) There is very little recharge of groundwater because rapid urbanisation has reduced open spaces and natural surfaces, preventing rainwater from seeping into the ground and replenishing the water table.

(iii) Tubewells are important in Punjab because the state has fertile alluvial soil and a high demand for irrigation to support intensive farming, especially of wheat and rice. The presence of abundant groundwater makes tubewells a reliable source of irrigation.
