Reclaimed Land Uses

Restored land can be returned to productive use in a variety of ways that benefit communities and the environment.

Reclaimed land uses: rice paddies restoring agricultural viability, fish farming ponds creating safe aquaculture ecosystems, and empowerment through knowledge
The 1-hectare scale model: four lined ponds arranged as rice paddies and fish farming ponds, transforming a toxic liability into a precisely engineered engine for sustainable food and economic production

Rice paddies

Contaminated land can be restored to support agriculture. Lined ponds and controlled water management create healthy rice paddies that provide food and livelihoods.

Our process ensures residual contaminants are reduced to safe levels, allowing crops to grow without risk to people or ecosystems.

Fish farming ponds

Aquaculture is a productive use for restored land. Our pond designs include proper water depth, slopes, dykes, and inlet/outlet channels to create healthy environments for fish farming.

From small ponds to larger commercial operations, we design systems that support sustainable fish production.

Construction & development

Reclaimed land can also support responsible construction and development. Our engineering designs and earthworks create stable, safe sites ready for the next phase of use.

Engineering details

Our pond designs include precise dimensions, cross-sections, and water management structures to ensure long-term performance.
