Irrigation farming is highly practiced in Northern Nigeria because of inadequate rainfall and the presence of many rivers. Northern Nigeria is located in the Sahel region, which is characterized by low and erratic rainfall. Irrigation is a method of watering crops artificially by diverting water from rivers, lakes, or underground sources to the fields. The presence of many rivers such as River Niger, River Benue, and their tributaries provides a reliable source of water for irrigation farming. Additionally, irrigation allows farmers to grow crops throughout the year, regardless of the season. Therefore, the correct answer is option (C) inadequate rainfall and presence of many rivers.
