RootSense: Strengthening Agricultural Drought Resilience
Enhanced Soil Moisture Monitoring in Sub-Saharan Africa
A Xylem Institute Root Program Initiative
Executive Summary
Agricultural drought threatens the livelihoods of millions across Sub-Saharan Africa, where rain-fed farming sustains entire communities. When soil moisture becomes insufficient for crop growth, the cascading effects devastate agricultural yields, compromise food security, and deepen economic hardships.

Why Soil Moisture Monitoring?
Soil moisture monitoring represents a paradigm shift in agricultural drought detection, offering critical advantages over conventional approaches that rely on rainfall data, vegetation indices, or meteorological drought indicators.
vs. Rainfall-Based Approaches
- Direct plant water availability: Soil moisture measures water actually available to crops, not just precipitation received
- Accounts for soil properties: Different soil types retain different amounts of water from the same rainfall
- Considers water losses: Incorporates evapotranspiration, runoff, and deep percolation that rainfall data ignores
- Timing precision: Reveals when crops experience water stress, regardless of recent precipitation patterns
vs. Vegetation Index Approaches
- Earlier detection: Soil moisture stress occurs 2-4 weeks before vegetation indices (NDVI, EVI) show drought impact
- Predictive capability: Enables proactive rather than reactive drought management
- Cloud independence: Ground-based soil sensors work regardless of weather conditions that can obscure satellite vegetation data
- Root zone focus: Measures moisture where plant roots actually access water, not surface greenness
vs. Conventional Drought Indices
- Agricultural relevance: Directly correlates with crop water stress rather than meteorological conditions
- Spatial precision: Provides field-level resolution instead of broad regional drought classifications
- Management actionability: Offers specific irrigation timing guidance rather than general drought declarations
- Yield prediction: Strong correlation with crop productivity enables accurate harvest forecasting
🔬 Scientific Advantage: The Soil-Plant-Atmosphere Continuum
Soil moisture monitoring captures the critical interface where atmospheric water inputs meet plant water demands. Unlike surface-based measurements, our multi-depth sensor networks monitor the entire root zone (0-100cm), providing a complete picture of water availability throughout the growing season. This approach recognizes that agricultural drought is fundamentally about plant-available water, not meteorological conditions.
Early Warning
Detect drought conditions 2-4 weeks before vegetation stress becomes visible, enabling preventive action.
Precision Agriculture
Enable field-specific irrigation decisions based on actual root zone water availability.
Yield Optimization
Maximize crop productivity through optimal water management and stress prevention.
AI Methods & Delivery Innovation: The Game-Changer
RootSense leverages AI-powered crop condition prediction using soil moisture data, revolutionizing how we transform satellite observations into actionable agricultural intelligence.
AI Crop Prediction
- Soil moisture → crop stress prediction models
- Machine learning algorithms trained on ground-truth
- Real-time crop condition forecasting
- Yield impact assessment 2-4 weeks early
Satellite Recalibration
