@PatrickHeizer Just because water is being used doesn't mean it completely leaves the system; some evaporates, but most infiltrates and continues the flow.
This part of Brazil was not used for agriculture, it does not support dense forests like the Amazon, but it has potential for energy production, ease of building access roads, and little weathering, resulting in low maintenance.
Brazil has six biomes.
Most people can name one.
Everyone knows the Amazon rainforest.
Almost no one outside Brazil knows the Caatinga.
The Caatinga is the only biome on Earth found entirely inside Brazil.
It covers about 10 percent of the country and more than half of the Northeast region.
The name comes from an Indigenous word meaning "white forest."
It is a dry land of thorn trees, cactus, and red rock that turns green after a single rain.
Around 27 million people live inside it.
That makes it the most densely populated semi-arid region on Earth.
Hundreds of its plant and animal species exist nowhere else on the planet.
For most of history the world wrote off this land as a wasteland.
Then the world learned what the sky above it is worth.
The Caatinga interior gets about 6.5 kilowatt hours of sun per square meter every day.
That puts it on par with the Australian outback and well above Germany or Spain.
Solar farms here run at 20 to 25 percent capacity, while European farms run at 11 to 15 percent.
One of the largest solar parks in Latin America sits in Piauí, inside this biome.
The state of Bahia alone holds the highest solar build-out potential in the country.
The land everyone called empty turned out to be one of the best power sources in the Western Hemisphere.
Most foreign investors have never heard the word Caatinga.
Brazil's potential for food production is still very large; even without opening new areas, it's possible to work with conservation management and produce foods with higher added value, such as fruits and vegetables.
Most people miss this: it costs more to truck soybeans from Mato Grosso to Santos than to ship them from Santos to China.
The binding constraint sits inland. Paved road, rail, and barge capacity, not ocean freight.
Last week the STF cleared Ferrogrão 8-1, with the auction now set for H2 2026.
The line runs 933 km from Sinop to the Tapajós, where grain transfers to barges bound for Barcarena and Vila do Conde.
The export ceiling resets when that line is built.
Many farmers live in remote locations where fiber optic internet doesn't reach.
StarLink is their only broadband internet option.
I always recommend it to everyone I come into contact with.
I've already bought an antenna for my parents and uncles,
and now I'm waiting for my StarLink Mini to arrive so I can take it with me on trips.
Imagine a Brazil where you board a train in São Paulo and step off in Rio 105 minutes later.
Imagine every coastal capital linked, from Porto Alegre to Belém.
Imagine Brasília as the hub with 5 bullet train lines reaching across the country.
Even Manaus, the biggest city in the Amazon, on the grid.
That is the map I see.
16,600 km of track.
A real grid for a country of ~213 million people.
The São Paulo to Rio train has been on paper since the 1980s.
Almost 40 years of plans.
Zero track in the ground.
The drive between those two cities still takes 5 to 6 hours (depending on traffic).
50 million people live in that corridor.
About the size of South Korea.
China built 50,000 km of bullet trains in 17 years.
Brazil built 0 in 40.
At China's pace, the Brazilian network gets built in 20 years.
At Brazil's pace, 50.
The price tag is about $500 billion in today's dollars.
Closer to $1 trillion by the time the last track is laid.
Every dollar spent comes back as $2 to $3 in growth.
That is $2 to $3 trillion added to Brazil's GDP.
Land prices jump the moment the project becomes real.
Cities along the route gain value 20 years before the train arrives.
The corridor leads.
The train follows.
The biggest infrastructure project of the 21st century is not in China.
It is in Brazil.
It just has not been built yet.
@Starlink What Starlink promotes is nothing less than a revolution in the ease of having internet in areas where fiber optics will never reach, I have already bought two antennas and now another mini model. I would like to be able to contribute more to the company through my travel project
@drewcrawford_ And there is still much room for improvement, working with conservation management to reduce production costs and become less susceptible to adverse weather conditions and price fluctuations.
The water used in agriculture cannot be considered an expense; this water comes from artificial reservoirs, it is water that has been retained, so it nourishes the plants, generates life, diversifies the environment, and then returns to its natural cycle, partly through the river, partly through the clouds.
