  • Not often. I think in general they are not that aligned, it’s just that overly restrictive zoning and other bad policies have created such a severe crisis that the free market solution, which in a better society we might spend more time critiquing, has become dramatically superior to the status quo.

    I think long-run we should still develop better systems to build and distribute housing according to the needs of the community as a whole instead of private investors and the wealthy, but those systems today are virtually non-existent, and they take time to build. Today, people are literally dying on the streets because housing is too expensive. I think it’s harmful to be too ideologically purist about solutions in the midst of such a serious crisis.












  • Generally, the depth that tree roots grow to varies greatly depending on soil conditions and species and isn’t very well studied due to the difficulty and destructive nature of such research, so this might not be fully answerable. In most cases, tree roots won’t grow very deep in poorly oxygenated, wet soils but I don’t have much experience with the roots of these species, so they could be exceptions. Certainly their ability to survive and grow in these aquatic environments that are deadly to other trees suggests that they might be.

    Another factor is that if there is a seasonal fluctuation in water level, which would be the case in most places on earth, then the roots can grow deeper during the dry season and might be partially underwater during the wet season, similar to what you’ve depicted here.



  • Great work researching this!

    In term of those trees–Taxodium distichum is very similar to T. mucronatum and will make a great replacement for a New Orleans version of chinampas. Many botanists now consider them part of the same species and it takes an expert to even tell them apart.

    Willows are a more diverse group but in general they all grow well in flooded areas, so I am sure another species will work for this. I am not familiar with the specific species found in that area. I would probably just pick one that has a similar size and structure and call it good enough. Or you could just leave it as generic willows if you want since it might take some experimentation to pick the best species.

    That said, I think other flood-tolerant trees could have their place in this system. Really it’s just substantial woody plants that can grow in flooded, disturbed soil. I don’t know the species in Louisiana super well since I don’t live there but if there are other species that fit that bill I think you could also include them.
