Satellite NDVI gives dead land a credit score (300-850) and unlocks its agricultural value by measuring vegetation health from space. By utilizing free Sentinel-2 data captured every five days, we can assess crop health, land use history, water availability, and soil degradation trends to transform unverified rural areas into data-backed assets.
The Problem: How Do You Value Land Nobody Has Measured?
In Mozambique, a vast majority of rural land remains unsurveyed and unrecorded. Because formal documentation is often missing, local farmers struggle to prove the productivity of their soil to those who could support their growth. Maputo Bridge Capital (MBC), founded by Anselmo Boaventura in Fort Worth, Texas, works to bridge these gaps by connecting sponsors with verified smallholder farmers in Mozambique, specifically through our work with the COJAZ cooperative in Zambezia.
Land without data is dead land. Land WITH data is potential.
The Solution: Satellite NDVI
NDVI stands for Normalized Difference Vegetation Index. It is a scientific measurement of plant health, calculated by comparing how much red and near-infrared light is reflected by vegetation cover.
| NDVI Value | What It Means | Land Quality |
|---|---|---|
| 0.6-0.9 | Dense, healthy vegetation | Excellent |
| 0.4-0.6 | Moderate vegetation | Good |
| 0.2-0.4 | Sparse vegetation | Fair |
| 0.0-0.2 | Bare soil or dead vegetation | Poor |
| <0.0 | Water, clouds, or built-up area | N/A |
How NDVI Assesses Land Potential
| Step | What Happens | Data Generated |
|---|---|---|
| 1. Satellite captures imagery | Sentinel-2 passes over every 5 days | Raw NDVI data |
| 2. MBC processes NDVI | Cloud-free composites over 90 days | NDVI score 0-1 |
| 3. Historical comparison | Compare to 5-year average | Trend (improving/declining) |
| 4. Convert to land score | 300-850 scale (like FICO) | Potential score for the land |
| 5. Match to needs | Higher NDVI = better outcomes | Resource allocation |
The NDVI-to-Value Conversion
| NDVI Range | Land Score | Potential Value (1 ha) |
|---|---|---|
| 0.6-0.9 | 750-850 (A) | $3,000-8,000 |
| 0.4-0.6 | 650-749 (B) | $1,500-3,000 |
| 0.2-0.4 | 550-649 (C) | $500-1,500 |
| 0.0-0.2 | <550 (D) | $200-500 |
A satellite that costs $0 to query determines whether land potential is assessed at $200 or $8,000 per hectare.

What NDVI Reveals About the Land
Crop Health
| What Satellite Sees | What It Means | Action |
|---|---|---|
| High NDVI (green) | Healthy crops growing | Land is productive |
| Low NDVI (brown) | Crops stressed or absent | Needs water/fertilizer |
| Declining trend | Soil degradation | Soil remediation needed |
| Improving trend | Good management | Continue practices |
Land Use History
| What Satellite Sees | What It Means | Value Impact |
|---|---|---|
| Continuous vegetation (5 years) | Consistently farmed | +20% value |
| Intermittent vegetation | Abandoned/fallow | -10% value |
| Deforestation trend | Trees being cut | -30% value |
| New vegetation appearing | Land being developed | +15% value |
Water Availability
| What Satellite Sees | What It Means |
|---|---|
| Green NDVI year-round | Irrigation present or high rainfall |
| Green in rainy season only | Rain-fed (no irrigation) |
| Brown patches in fields | Uneven water distribution |
| Green near water bodies | Good irrigation potential |
How NDVI Creates Transparency From Nothing
Before NDVI (Dead Land)
| Metric | Status |
|---|---|
| No data | Invisible to observers |
| No proof of productivity | Cannot demonstrate yield |
| No history | Cannot assess trends |
| No monitoring | Cannot manage risks |
| Total capital | $0 |
After NDVI (Live Data)
| Metric | Status |
|---|---|
| NDVI score = 0.65 | Land rated "Good" (Grade B) |
| Productivity confirmed | Capacity verified |
| 5-year history available | Patterns visible |
| Real-time monitoring | Insights updated |
| Market value established | Transparency enabled |
The satellite costs nothing. The data costs nothing. But the clarity it creates is worth $1,500-3,000 per hectare.
What This Means for a Smallholder Farmer's Season
For a farmer, this technology provides a way to document the success of their harvest and monitor the health of their crops throughout the season. When a sponsor provides support through MBC, 92% goes directly to the local seed and fertilizer shop, while 8% covers verification. Satellite data helps track the progress of these crops, ensuring that field verification aligns with what is happening on the ground in Zambezia.
The Future: Continuous Land Monitoring
Looking ahead, research directions include the integration of AI, machine learning, and blockchain to create immutable records of land health. Our vision is for every hectare in Mozambique to be monitored by satellite and scored automatically, which would provide transparency for sponsors and support for agricultural cooperatives.
Frequently asked questions
Q: What is NDVI? A: NDVI stands for Normalized Difference Vegetation Index, a measure used to determine vegetation health based on how plants reflect red and near-infrared light.
Q: How often is the data updated? A: Sentinel-2 satellite imagery captures data every 5 days, allowing for frequent monitoring of land and crop conditions.
Q: Can satellite data show water availability? A: Yes, NDVI reveals water availability by identifying year-round green vegetation, which often indicates irrigation or consistent rainfall.
To help a smallholder farmer in Mozambique prepare for their upcoming season, you can sponsor a farmer from $25 at /donate. Please note that sponsorships are gifts to support farmers, not investments, and are not tax-deductible.
