The Malabrava River

I was not going to walk for about a while. It should have taken me normally here, no more than 20 minutes. But it took me all of like three and a half hours I think to get back to where I could get my bearings. Such as these landscapes are beautiful to look at, they are hard landscapes to make a living in. So what is it, is it that the Malabravari couldn't sustain itself and needed more? There wasn't too much agriculture in the first millennium but how? The bore wells and irrigation schemes of the 20th century have played a huge role in making agriculture a bit sustainable.
