Until the 1950s, paddy fields were hanging in Manhara field. Many farmers from Kathmandu not only used to plant paddy here but also used to solve their financial problems by selling it. The irrigation of the Manhara river in the fields also made paddy production possible. But in recent times, the Manhara coastal area is slowly becoming desolate as the farmers sell sand instead of rice and make the fields barren.

When the farmers here began to sell sand instead of rice from the pits of the fields, Manhara also got deeper . The water of the river flowing near the farm stopped flowing in the culvert, and with the help of an electric machine, it became necessary to irrigate by drawing water from pipes. In this way Manhara finally became a place of sand production . 

After the sand began to recede from 2038, in the 50s, the Manhara deepened and reached a state of irrigation only after pumping water. This situation has come after starting to earn money by contracting from the sand of Manhara . Since the 40s, Manhara was made by the government to earn money by saving sand. Since then, the river has started getting deeper than the private land of farmers. At that time, no one was very interested in the small amount of rice cultivation. 

After the political change of 2046, the farmers appealed to the former district development committee not to contract sand. But since sand is one of the main internal resources of Jivis, the farmer's voice was not heard. From Manhara, 2 to 300 trucks were going out of the sand valley every day. Farmers used to get 250 rupees and contractors 450 rupees per trip. In 2050, Kathmandu, Bhaktapur and Lalitpur published a tender notice of 37 lakhs for sand extraction. At that time, the income was considered huge. 

Illegal mining also started here after farmers stopped planting rice and started selling sand themselves. The structure of the development was also greatly hampered when the excessive amount of sand started to be taken from the depth near Manarharapur . However, due to the collusion of the local police administration, sand smuggling did not decrease, it continued to increase. Incidents of sand smuggling and the collusion of local administration are not only heard now and then. 

About 44 years ago today, sand mining, the reason for the disappearance of paddy in Manhara district, local level income sources and administrative coordination, Kantipur Dainik published a news titled 'Rice selling farmers started selling sand' on 23rd March 2050 .
