       | 
       | Truth is, there's 2 types of people that go to the central
       | market, old people and tourists.
       | 
       | Everyone else drives to Mercadona, a supermarket like any other,
       | in their Mercedes. You can also buy fantastic veges and fruits
       | there but without dealing with 5-6 merchants to get what you
       | need.

         | The main difference (although that is not clear from the
         | article) that this system is based on fixed proportions of
         | usable water volume whereas water rights in the Western US
         | states are mostly setup in order of seniority and (at least
         | historically) with no adjustment mechanism for usable flow.
         | That means that if users with senior rights use up all the
         | waters, junior rights holders and the natural river itself get
         | no water.

       | I've always wondered how much of Spanish colonialism is an
       | emulation of their colonization by Arab Muslims.

       | 
       | So this is a model for sustainability. How does this scale to

       | Valencia's a cool place to visit, they did a number of
       | interesting things in the last few decades:
       | 
       | * after a devastating flood in the 1950s they "moved" the river
       | out of the city and they used the original channel to build a
       | 10km long park with tons of infrastructure for sports and
       | recreation: https://metropolismag.com/projects/how-valencia-
       | turned-crisi...
       | 
       | * they have a network of docked city bikes with ~300 stations
       | around the city. Docked bikes are not perfect, but don't cause
       | the mess that dockless bikes do. It costs EUR30/year and every
       | ride is free for 30min. (it's not unique, as other cities have
       | similar networks, but it's really well executed)
       | 
       | * their Ciudad de las artes y ciencias (City of arts and science)
       | is a beautiful complex with a museum, cinema, oceanographic park
       | and iirc there's even a night club somewhere there. Really cool
       | place for tourist and local residents to hang around:

         | There's actually 3 :D Umbracle, the one that exists open air
         | under the awnings is great in the summer time air. It only runs
         | during the warmer months as the locals can't stand the 20C
         | night temperature.
         | 
         | Valen-bici is super convenient, they are pretty heavy steel
         | framed machines but everythings flat so it's not a great
         | bother.
         | 
         | The real gem is the extensive bike lanes that stretch upwards
         | of 20km out from the city. Every main road has a bike lane.
         | Electric scooters were the real ticket and I had one while I
         | was there. ALmost went a year carbon free transport.

       | I have no problem with stating that it was built, or implemented
       | by Moorish rulers. I have a problem with 'invented'.
       | 
       | Waterways specifically for irrigation, in near-identical (and
       | many better) designs have been around significantly longer than
       | 1,200 years. The Romans, Egyptians, Mesopotamians, Incas, Mayans,
       | and so on. Go to central Arizona in the USA to see about 700
       | miles of irrigation canals built by the Hohokams. Or, check out
       | the Assyrians' inverted siphon for the Nineveh Aqueducts.

         | Maybe "invented" is in relation to the specific social system

         | fairness. It sounds much better than the system where I
         | live(Colorado), which is "first in time, first in right",
         | meaning the first person to use water from a river gets to
         | claim whatever water they use as their own for eternity,
         | meaning anyone else who comes along later can't have any water
         | at all until the senior rights holder gets their fill.

           | 
           | The FIT/FIR system is not going to survive. Of this, I am
           | certain. It's a concept based on mistaken ideas about the
           | amount of water in the American southwest, in turn based on a
           | particularly wet couple of decades at the turn of the 20th
           | century. If the current drought continues, or at some other
           | point in the future, the implicit farming-centric nature of
           | FIT/FIR is going to clash with the desires of these states'
           | growing populations. Farming is not going to win (by farming,
           | I mean large scale industrial production, mostly for export).

       | As temperatures rise places that use aqueduct and flood

       | evaporation during transport.
       | 
       | Fortunately people out on the American plains have this figured

         | 
         | So on the one hand, it's a huge problem, but on the other, it's
         | not.

         | The area being serviced isn't massive and the chanels are

       | Legend has it that when God created the Valais, he asked the
       | local farmers whether they wanted rain, or whether they would
       | take care of their own irrigation. After a brief consultation,

       | 
       | It was hypnotic watching the sharecropper, with just a hoe,
