Despite high rainfall, the need for irrigation in Meghalaya arises due to:

Uneven distribution of rainfall
Hilly terrain and rapid runoff
Long dry season in some areas
All of the above

The correct answer is: d) All of the above

Meghalaya is a state in northeastern India. It is the wettest place on Earth, with an average annual rainfall of over 11,871 mm (467.4 in). However, the rainfall is unevenly distributed, with most of it falling during the monsoon season from June to September. The rest of the year is relatively dry, with some areas experiencing a long dry season.

The hilly terrain of Meghalaya also contributes to the need for irrigation. The steep slopes of the hills cause the rainwater to run off quickly, making it difficult for crops to get the water they need.

As a result of these factors, irrigation is essential for agriculture in Meghalaya. It helps to ensure that crops have access to water throughout the year, even during the dry season. Irrigation also helps to improve crop yields and reduce soil erosion.

Here is a brief explanation of each option:

  • Uneven distribution of rainfall: The rainfall in Meghalaya is unevenly distributed, with most of it falling during the monsoon season from June to September. The rest of the year is relatively dry, with some areas experiencing a long dry season. This makes it difficult for crops to get the water they need, and irrigation is essential to ensure that they have access to water throughout the year.
  • Hilly terrain and rapid runoff: The hilly terrain of Meghalaya also contributes to the need for irrigation. The steep slopes of the hills cause the rainwater to run off quickly, making it difficult for crops to get the water they need. Irrigation helps to slow down the runoff and make it available to crops.
  • Long dry season in some areas: Some areas of Meghalaya experience a long dry season, which can make it difficult for crops to grow. Irrigation helps to provide water to crops during the dry season, which can help to improve crop yields.
