[Maize](https://www.materialinsights.org/commodities/maize/) (commodity) and [Water](https://www.materialinsights.org/commodities/water/) (commodity): 1 relationship.

## How they are linked

### 1. Price link: irrigation demand

*Cost and price · Moderate · Both ways*

Crop prices guide what irrigation is worth to growers, so farm incomes feed into water bids. The link is loose: monthly moves barely correlate (0.05) but yearly changes correlate at 0.55, as both respond to seasons and weather rather than to each other.

- **0.05** monthly change correlation
