How to complain about the illegal behavior of river dredging?

The most direct way is to complain to the local land and resources department about their destruction of cultivated land, because Article 36 of the Land Management Law clearly stipulates: "It is forbidden to occupy cultivated land to build kilns, graves or houses, and it is forbidden to dig sand, quarry, mine and borrow soil on cultivated land." If you make sure that their cultivated land is basic farmland, it will be more favorable, because the state has stricter measures to protect basic farmland. Article 74 stipulates the punishment measures: in violation of these regulations, those who occupy cultivated land to build kilns and graves, or build houses, dig sand, quarry and borrow soil on cultivated land without authorization, which damages the planting conditions, or cause land desertification and salinization due to land development, shall be ordered by the land administrative department of the people's government at or above the county level to make corrections within a time limit and may also be fined; If a crime is constituted, criminal responsibility shall be investigated according to law.

Dredging soil from cultivated land involves land reclamation. If they promise to restore the original state after sand pumping, they must pay the corresponding land reclamation deposit (determined by the land and resources department).

According to my experience, anyone who damages cultivated land by dredging sand on the river course shall be ordered to stop, restore the cultivated land to its original state within a time limit, and may also be fined. Compared with next year, it should be applicable.

Agricultural law, property law and rural land contract law may all have relevant provisions.
