The correct answer is: d) All of the above.
Traditional irrigation systems in Meghalaya often involve bamboo drip irrigation, diversion canals, and small-scale water harvesting.
Bamboo drip irrigation is a traditional method of irrigation that uses bamboo pipes to drip water directly onto the roots of plants. This method is very efficient in areas with low rainfall, as it minimizes water loss due to evaporation.
Diversion canals are artificial channels that are used to divert water from rivers or streams to agricultural fields. This method is often used in areas with high rainfall, as it allows farmers to irrigate their fields even during the monsoon season.
Small-scale water harvesting is a method of collecting and storing rainwater for use in irrigation. This method is often used in areas with low rainfall, as it allows farmers to store water for use during dry periods.
All of these methods are effective in irrigating crops in Meghalaya. The choice of method depends on the specific needs of the farmer and the available resources.
