Innovation and practical technology
Technology relevant to food and agriculture, trade, resources and supply chains and climate and hazards: what it can do, the constraints it faces and its consequences for people and institutions.
Innovation and practical technology in four parts.
Evaluate before adopting.
- 01
Need
Which problem does the technology address, and for whom?
- 02
Evidence
What has been demonstrated, under what conditions, and what remains untested?
- 03
Constraints
Cost, skills, infrastructure, data and governance requirements.
- 04
Consequences
Effects on safety, rights, equity and the environment.
What could change food system practice, and what it still has to show.
| Technology | What it could change | What remains to be shown |
|---|---|---|
| Satellite crop-type and condition mapping at field scale | Earlier, subnational yield outlooks where surveys are slow | Accuracy on smallholder plots and mixed cropping; cloud in the growing season |
| Heat- and drought-tolerant varieties | Lower yield sensitivity to the extremes that drive synchronous failure | Performance across farming systems; seed system reach and affordability |
| Off-grid cold storage | Reduced post-harvest loss where grids are weak | Maintenance, financing and use at village scale |
| Digital market information for farmers | Better price discovery and less distress selling | Connectivity, literacy and whether information changes bargaining power |
| Precision fertiliser application | Less nitrogen use per unit of output and less exposure to gas prices | Cost and agronomic advice for small farms |
