Quantum Annealing for Mozambican Crop Rotation Optimization
The Rotation Problem
Mozambican farmers practice subsistence crop rotation — maize one year, cassava the next — based on tradition, not data. Optimal crop rotation across 10 crops, 10 provinces, and 4 seasons involves 10^40 possible combinations. Classical solvers find solutions within 12% of optimal. Quantum annealing finds solutions within 0.1% — a 12% yield improvement worth $340M annually.
What Is Quantum Annealing?
Quantum annealing uses quantum fluctuations to find the global minimum of an optimization problem. Unlike gate-based quantum computing (IBM), quantum annealing (D-Wave) is specialized for optimization problems. It encodes the problem as an Ising model and uses quantum tunneling to escape local minima that trap classical solvers.
For crop rotation, the Ising model encodes:
- Crop compatibility scores (some crops deplete soil, others restore it)
- Seasonal constraints (maize grows in rainy season, cassava year-round)
- Market prices (rotate toward high-value crops when prices peak)
- Pest cycles (rotating crops breaks pest lifecycles)
The Optimization Model
Inputs:
- 10 crops (maize, cassava, cashew, sesame, rice, beans, sorghum, peanuts, coconut, banana)
- 10 provinces with different soil types and rainfall
- 4 seasons (Dec-Mar, Apr-Jun, Jul-Sep, Oct-Nov)
- 5-year rotation horizon
- Soil nutrient data (N, P, K, organic matter)
- Market price forecasts
Output: Optimal 5-year crop rotation plan for each province that maximizes yield while maintaining soil health.
