Sudqi canal project

🌊 Derawi Tides: Coastal Canal & Artificial Salt Lake Project

The project proposes the construction of a 7-kilometer canal to connect a large inland depression (approximately 2,000 km²) to the Atlantic Ocean. This connection would allow seawater to flow naturally into the منخفض area, forming a new artificial saltwater lake.

🔑 Key Components

1. Artificial Salt Lake Creation

• Seawater inflow fills the depression, creating a stable saltwater body.
• The lake could support marine ecosystems and controlled aquaculture.

2. Aquaculture Production

• The project aims to produce ~20,000 tons of fish annually through large-scale marine farming.
• Could include high-value species (e.g., sea bass, shrimp, or algae-based systems).

3. Tidal / Hydraulic Energy Generation

• Water flowing through the canal (especially if there’s an elevation difference) can drive turbines.
• This could generate renewable electricity similar to tidal or hydro systems.

4. Climate Impact (Carbon Capture)

• The salt lake may act as a carbon sink, potentially absorbing up to 1 million tons of CO₂ per year through:
  • Algae growth
  • Carbonate sediment formation
  • Biological activity

🌍 Challenges 1.Rising global demand for fish while wild fish stocks are declining (overfishing, ecosystem stress) 2.Energy poverty and high electricity costs in Mauritania 3.Increasing CO₂ emissions and accelerating climate change 4.Limited sustainable sources of protein and food security risks 5.Dependence on fossil fuels for energy production 6.Underutilized coastal/depression land with no economic output

✅ Benefits / Solutions 1.Produces ~20,000 tons/year of fish through sustainable aquaculture 2.Reduces pressure on wild fisheries and improves global food security 3.Generates renewable energy from water flow (tidal/hydraulic) 4.Provides affordable, clean electricity for local communities 5.Captures CO₂ using algae and saltwater ecosystem (climate mitigation) 6.Creates new economic activity, jobs, and regional development 7.Utilizes unused land by transforming it into a productive saltwater lake 8.Enables algae production for feed, biofuel, and industrial use
