HOW MUCH BOTSWANA IS LOSING WITHOUT WATER HARVESTING 🌍
Key Reality Botswana receives rain, but: Very little is harvested Most is: Lost as runoff Evaporated due to high temperatures Not stored at household or farm level Quantifying the Loss (Strategic Estimate) Let’s break it down: 1. Rainfall Volume Potential Botswana land area ≈ 581,000 km² Rainfall ≈ 416 mm/year Total rainfall volume: ≈ 241 billion cubic meters annually Even if only 5% is harvestable , that is: ≈ 12 billion cubic meters 2. Compare with Current Water Use Botswana heavily depends on: Dams Groundwater (≈ 49% of supply) Yet: Only a tiny fraction of rainfall is captured 3. Economic Loss from Non-Harvesting Let’s convert to money: If: 1 m³ water ≈ P10 (average domestic value) Then: 12 billion m³ potential = Even if we reduce this to realistic capture: 1% utilization = P24 billion 0.5% utilization = P12 billion Conservative Conclusion Botswana is likely losing: P10 billion – P100+ billion annually in unreali...
