What has to be verified before you sign.

Investigations into the Federal 45 corridor: its geography, its industrial history, its water, its power and its people. We publish the sources behind every figure and flag explicitly where those sources contradict one another.

    What is the Bajío?

    The alluvial plain that made the Bajío the granary of New Spain is the same flat, well-connected ground that makes it industrial today.

    Population growth

    Available labour, yes. But every new resident is also water demand on aquifers already in deficit.

    The electrical grid

    The constraint is not generating power. It is evacuating it. In 2026 several tenders were declared void explicitly for grid saturation.

    The rainfall

    Industrial water in the Bajío does not come from this year's rain. It comes from aquifers that recharge slowly and are pumped fast.
