#resilience
brooo I just found the best paper (article?) about CAM plants appropriate for food production in a region the writers term “Aridamerica” (in contrast with mesoamerica) that encompasses northern mexico, the sonoran desert, and part of arizona and nevada….it’s so fuckin good
An Aridamerican model for agriculture in a hotter, water scarce world
The article is the work of some researchers who examined ethnobotanical and historical sources, interviewed native people, and did ecological surveys in “Aridamerica”
Primarily they drew from the current and historical practices of the Comcaac (Seri people), O'odham, and Pima Bajo peoples. Here are a few excerpts from the article I really liked!
Agricultural visionaries from Argentina, Australia, North America, and elsewhere have been calling for “new roots for agriculture” for more than 40 years (Felger, 1975; Jackson, 1980). Their visions favor high biodiversity-low input agroecosystems, with greater emphasis on perennial polycultures. To quote pioneering desert botanist Richard Felger, to whom this article is dedicated, we must “fit the crops to the environment rather than remaking the environment to fit the crops.” Yet, to date few agronomists have given sufficient attention to effective means to reduce heat or moisture stress in crops and livestock, or in the humans who struggle to manage them (Nabhan, 2013).
The majority of widespread crops (e.g., rice, wheat, soybean) are C3 plants with low water-use efficiency and reduced photosynthetic efficiency under high temperatures. C4 crops (e.g., corn, sorghum, sugarcane) have higher heat tolerance but usually require reliable irrigation in arid and semi-arid land settings. As temperatures increase, so do evapotranspiration and water input required to maintain crop yields. Thus, even drought- and heat-tolerant varieties of conventional C3 and C4 crops may be unable to weather—let alone mitigate—the stressful agronomic conditions predicted for arid zones over the coming century. In contrast, wild desert plants have evolved multiple strategies to cope with heat and drought (Gibson, 1996). Desert plants with the crassulacean acid metabolism (CAM) pathway uptake CO2 nocturnally when temperatures are cooler, thereby optimizing water-use efficiency (Nobel, 2010).
I really like the points they make here about C4 plants! Corn and sorghum are often listed as being more suitable for arid climates because of their improved temperature tolerance and water use efficiency compared to (for example) wheat or soybean. That said…both were originally tropical plants iirc, and while there are certainly drought-tolerant cultivars of both, they still use a *lot* of water in very hot and dry regions, and those well adapted cultivars aren’t the most commonly grown.
After gathering a list of plants commonly used as crops by the native people of these areas “For each species, we determined the photosynthetic pathway (C3, C4, CAM) and categorized water-acquisition strategy as extensive exploiter (e.g., Prosopis/mesquite), intensive exploiter (e.g., Salvia columbariae/chia, Phaseolus acutifolius/wild tepary bean), or water storer (e.g., Agave/agave, Opuntia/prickly pear)”
It’s really interesting to think abt those different drought strategies! For reference, extensive exploiters tend to have very wide+deep root systems that collect water from an extensivearea. Intensive exploiters tend to be found near temporary water courses that only hold water temporarily/for part of the year. This could mean washes/dry streambeds that flood in a storm, or rivers that dry up outside of the monsoon season. I know tepary beans typically grow quickly (often quoted as taking only 60 days from growth to seed set!) when water is available, then die and weather the hottest and driest season as dormant seeds. Water storer is pretty self-explanatory–agave and prickly pear are succulents that can store a tremendous amount of water in their tissues, saving it to tide them over until the next precipitation event.
Ultimately, the article graded a variety of plant genera on their agroecological suitability (how well they grow in an arid environment), any potential medicinal uses, their community/social value (cultural importance, providing shade in communal areas, etc.), and their agronomical suitability (can it be grown at scale, is there a market for it, etc.) I won’t bother to list them here–you can go see the whole chart in the linked article–but it’s a very interesting list!
I just wish I could tell you that I miss you,
I’m mad at you but I still love you
And I want you back in my life.
The worst you can say is no, so why am I so scared?
Sometimes it feels easier to just leave
Cut people out of your life the second they cross you
Never let anyone get too close
Look out for yourself and let everyone else do whatever it is they do.
It’s also lonely going through life by yourself
So worried about others that you end up locked away in your room every night
Wondering if anyone will ever actually know who you really are instead of the person you pretend to be.
To my love
Thank you for always being by my side
When everyone in my life would leave me
I knew I could always trust you
And that gives me hope for a better future
One where we can be happy
I know I haven’t always treated you with kindness
You’ve seen parts of me that no one else has, yet you still want me to be happy
You want me to be a better me
I love you
So from me to me…
Please be my Valentine
I keep wanting to live my life in the past while everyone else is heading towards the future.
All the while I miss out on the goods things I have right in front of me in the present.
Why does the sun set?
The night lasts so much longer then the day.
Even though I know the sun will always come back,
The night frightens me.
As the darkens creeps in I lose sight of the future.
This all encompassing darkness hiding me from my loved ones and passions.
Still, at any moment, I know, the sun will rise.
So I will be patient, and have hope knowing that soon sunshine will wash over me again.
I can only speak for me, but—every time I survive depression, I have scars. But I also have a story. I never wish to have gone through the depression and parts of me remain broken, but a quiet strength also remains. I made it. It is worth celebrating.
Anyone else in health care being gaslit by the government, society, and their institution into feeling survivor’s guilt because even if things are crappy for you, they’re crappier for somebody else?
Really feeling for my primary care/family medicine, critical care, emergency/urgent/acute care, and mental health colleagues at the moment. This pandemic has been going on way too long, and no one seems to care about the fact that even when things were reopening, you were all still being worked into the ground (and through the crust of the earth into its molten core) by all the ripple effects of this pandemic uncovering the systemic inequities and BS that was just lurking in the shadows before 2019… All the stuff that health care workers, in general, managed to barely keep at bay from their sense of altruism and dedication (now obligation?) to their patients. If I’ve learned anything from COVID-19, it is that everyone will do their best to take advantage of you, and short of doing your job well, you actually don’t owe them anything.
You really do gotta take care of you first, otherwise this system will beat you down to nothing before you even realize it. “Resilience” is great and all, but it’s really just the system shifting all responsibility for surviving its BS onto its victims.
This system has been sick for a very, very long time. It’s gonna need a lot more than a bandaid and some yoga to rehabilitate it.

May you live an existence that doesn’t require constant resilience.
THIS.
I reblogged this a few hours ago, but I will reblog it again, because I just feel this SO STRONGLY.
I first learned about Moon Treesin the fall of 2015. One of the trees – a loblolly pine – had been planted at an elementary school just down the street from where I was living at the time. It wasn’t a new thing – it was planted back in 1977, during the period when most other Moon Trees where being planted around the country and the world – but because it wasn’t doing too well, it was in the news.…
“After seven years of experiments, it was clear to us that the remarkable attribute of resilience in the face of defeat need not remain a mystery. It was not an inborn trait; it could be acquired.”
