- Land reclamation is the process of creating new land from existing bodies of water or other natural landscapes.
- It is often done to create more space for urban development, agriculture, or infrastructure projects.
- Land reclamation can have negative environmental impacts, such as loss of natural habitats and disruption of ecosystems.
- Methods of land reclamation include dredging, filling in with soil or other materials, and building retaining walls or dikes.
- Land reclamation projects require careful planning and consideration of environmental factors to minimize negative impacts and ensure sustainable development.

Land Reclamation
- Process of creating new land or expanding existing land from water bodies or wasteland.
Methods:
- Hydraulic Fill: Pumping sediment-laden water into a designated area to create land.
- Landfill and Dredging: Excavating material from a donor site and placing it on a recipient site.
- Poldering: Constructing dykes around an area of water and draining it to create land.
- Other Methods:
- Artificial islands (e.g., Dubai's Palm Islands)
- Reclamation from wastelands (e.g., desert reclamation)
Purposes:
- Increase habitable or usable land
- Create commercial and industrial areas
- Protect against coastal erosion and flooding
- Enhance environmental areas (e.g., wetlands)
Considerations:
- Environmental impact (e.g., habitat disruption, water quality)
- Sustainability (e.g., subsidence, climate change)
- Engineering feasibility (e.g., soil stability, infrastructure)
- Economic viability (e.g., project costs, land value)
Benefits:
- Expansion of land for development and infrastructure
- Economic opportunities (e.g., tourism, real estate)
- Coastal protection and environmental preservation
Challenges:
- High costs
- Long-term sustainability issues
- Environmental concerns (e.g., habitat loss, pollution)
Examples:
- Netherlands (poldering)
- Singapore (landfill)
- Dubai (artificial islands)
- China (coastal land reclamation)
