Rice is a staple food of the people of Kirtipur Municipality. About 50 percent of the land is under agriculture of which a large part is planted with rice. Rice is a summer crop planted in June & July and harvested in September & October, a period that coincides with monsoon rain providing required water for the crop. Though rice is a water demanding crop, it is grown in Kirtipur as a rainfed crop because there are no reliable water sources for irrigation in most part of the area. In the past few years farmers have not been able to plant rice in normal time because of delayed monsoon. Since paddy needs to be harvested before the temperature begins to drop in September, it must be planted in time so that the crop remains in the field for adequate number of days for a good harvest. Global projections and several studies reveal that the uncertainty in monsoon rainfall patterns especially in south Asia is due to the impact of climate change which has its adverse effects in agriculture.
