Abstract: This data shows Land Commision (LC) Benefiting Areas associated with the works carried out by landowners typically in the 19th century, that individual landowners have a responsibility to maintain. The benefited lands identifies land that was drained as part of the schemes.Purpose: This data has been developed to identify the embankments that were created by landowners to reclaim land from rivers or the sea, typically in the 19th century. The Land Commission took over a number of embankments as part of it's work. The Minister and Land Commission were subsequently exempted from any responsibility for maintenance of land sold by the Land Commission under Section 10 of the Land Act, 1965, and this responsibility falls on the current landowners, in line with the provisions of the Land Acts. The purpose of the schemes was to create land for agriculture. In some cases embankments were created and the area behind was allowed to flood and flush out a number of times to reduce the salt content of the soil.
