Measuring Impact: How $200 in agricultural support generates $500 in income and 60% yield increases through verified field data. Maputo Bridge Capital, founded by Anselmo Boaventura in Fort Worth, Texas, connects sponsors with verified smallholder farmers in Mozambique to facilitate access to essential agricultural inputs. By ensuring resources reach the COJAZ cooperative in Zambezia, this model creates measurable impact that can be tracked through satellite-verified data and local documentation.

The $200 → $500 Income Impact
How $200 Creates $500 in Additional Income:
| Input | Cost | Impact |
|---|---|---|
| Improved seeds (2kg) | $40 | +30% yield (drought-resistant variety) |
| NPK fertilizer (50kg) | $80 | +40% yield (first-time fertilizer use) |
| Pesticide/fungicide | $20 | Prevents 15-20% crop loss |
| Insurance support | $20 | Mitigates risk of catastrophic loss |
| Total input cost | $160 | |
| Combined yield increase | +60-100% |
The Income Math:
| Metric | Without Support | With Support | Difference |
|---|---|---|---|
| Yield | 812 kg (738 kg/ha × 1.1 ha) | 1,300 kg | +488 kg (+60%) |
| Selling price | $0.20/kg (market rate) | $0.35/kg (off-taker) | +$0.15/kg (+75%) |
| Revenue | $162 | $455 | +$293 |
| Input cost | $0 | $160 | -$160 |
| Net income | $162 | $295 | +$133 first season |
Impact Over 3 Years:
| Year | Season | Yield | Revenue | Net Income |
|---|---|---|---|---|
| 1 | 1 | 1,300 kg | $455 | $295 |
| 1 | 2 | 1,400 kg | $490 | $310 |
| 2 | 1 | 1,550 kg | $543 | $343 |
| 2 | 2 | 1,650 kg | $578 | $360 |
| 3 | 1 | 1,750 kg | $613 | $375 |
3-Year cumulative additional income: $842 per farmer from the initial support provided to the seed and fertilizer shop.
The 60% Yield Increase: How It Works
Yield Decomposition:
| Factor | Yield Contribution | Mechanism |
|---|---|---|
| Improved seeds | +25-35% | Drought-resistant, higher-yielding varieties |
| NPK fertilizer | +30-40% | Nitrogen (growth), Phosphorus (roots), Potassium (disease resistance) |
| Pesticide/fungicide | +10-15% (loss prevention) | Prevents fall armyworm, maize stalk borer |
| Off-taker contract | +0% yield, +75% price | Better selling price = more income per kg |
| Combined | +60-100% |
Why Fertilizer Alone Creates 30-40% Yield Increase:
Mozambique fertilizer use is significantly lower than global averages, creating a 91% deficit compared to global norms. Applying 50kg of NPK on 1.1 hectares bridges this gap, allowing first-time fertilizer use to trigger a dramatic yield response. This process ensures that marginal lands become productive and soil nutrients are finally replenished, supporting the COJAZ cooperative in achieving long-term sustainability. J-PAL research confirms that farmers who gain access to fertilizer and improved seeds see significant increases in agricultural productivity.

The Smallholder Farmer's Season
For a smallholder farmer in Zambezia, the season is a critical period where timely access to inputs determines the year's outcome. By working with the COJAZ cooperative, farmers receive the necessary seeds and fertilizer to improve their plots. Throughout the growing cycle, monitoring via satellite and local verification ensures that inputs are used effectively. After the harvest, the resulting surplus and income gains allow farmers to contribute to a Community Fund, which supports the next generation of farmers, creating a cycle of growth and agricultural development.
Frequently asked questions
How much income does a successful harvest generate for a smallholder farmer?
Increased yields can generate significant additional income in a single season. Over a three-year period, cumulative additional income can reach substantial levels, providing a foundation for improved household stability and long-term agricultural sustainability.
How much do agricultural yields increase with proper inputs?
Yields can increase by 60-100% in a single season. These improvements are driven by three primary factors: using higher quality seeds, applying fertilizer effectively, and utilizing pest prevention techniques to reduce crop loss.
Why does fertilizer increase yields so dramatically in Mozambique?
Mozambique's current fertilizer usage is significantly lower than the global average. When farmers gain access to the right amount of NPK fertilizer, they see a dramatic increase in productivity compared to their baseline, which is essential for transforming rural subsistence farming into a more productive enterprise.
