Land reclamation refers to the process of creating new land from areas that were previously unusable, such as shallow lakes, wetlands, or areas with poor soil quality. This is typically achieved by filling the area with materials such as soil, sand, or waste, in order to raise the ground level and create new land for various uses, such as agriculture, urban development, or infrastructure projects. However, land reclamation can also lead to significant environmental problems if not carried out in a responsible manner.
