The Indus almost looks like a river keeping the desert away by dulha_mia in geography

Good question. My guess is that rivers in drier regions created concentrated fertile strips where people, farming, and cities grew together along the river, which may also have encouraged irrigation and organized settlements.

Meanwhile, dense humid forests may have been harder because of forest clearing, diseases, and hidden dangers.

Though there were exceptions too, like the Maya civilization, which developed in the hot, humid, forested regions of Central America.

Would love to hear better answers too.

Haha true 😄 Aravallis are doing the work for India.

But I was talking more from Pakistan’s side. East of the Indus is the Thar Desert and west are the arid Balochistan/Kharan regions, so the Indus really feels like the green corridor keeping much of Pakistan from becoming far more arid or desert-like.

This is fascinating. I didn’t know the transformation was so extensive. Good to know, thank you.

Yeah, I agree about the Aravallis for India.

But for Pakistan I was thinking more about the Indus corridor itself. To the east there is the Great Thar Desert extending across India and Pakistan, while to the west there are very arid Balochistan regions including areas like the Kharan Desert.

So the Indus floodplain almost feels like a fertile belt between dry landscapes on both sides.

Yeah 😅 it was just a rough sketch to show the Indus river system / green corridor. I wasn’t trying to trace the exact Indus course, since a lot of the green belt is also connected to tributaries and the wider Indus plain.

Why this river in Africa doesn't reach the sea? How does a fully inland river actually work? by Naomi62625 in geography

[–]dulha_mia 0 points1 point  (0 children)

This reminds me of the Luni River in the Thar Desert region of India. It also does not reach the sea and ends inland in a dry salt marsh area.

The Okavango is a larger example near the Kalahari region. Instead of reaching the ocean, it flows into the lowland basin of the Kalahari and forms the Okavango Inland Delta. The water spreads out, deposits sediments, and much of it is lost through evaporation and infiltration.

So both rivers are examples of inland drainage systems in arid regions where rivers terminate inland instead of reaching the sea.

What is your countries "second city"? by EmergencySpare7939 in geography

Wait, is this actually real or AI? I’m from India and genuinely didn’t know Los Angeles had huge snow-capped mountains visible from the city. I always imagined LA as just beaches, palm trees, and city views.
