Answer

Brief Explanations:

The question asks for a negative impact of farmland irrigation. The first, third, and fourth options are positive outcomes (food production in dry areas/droughts, improved farmer livelihoods). Only the second option describes a harmful effect: irrigation runoff carries fertilizers/pesticides into water sources, causing pollution.

Answer:

Increased runoff can pollute bodies of water.
