       | Cool project. Confusing headline. They made models to help
       | research land management strategies that would be potentially
       | helpful for bees.

           | 
           | They use a different matrix.

       | Wish I had some time to explore making a game out of something

       | possible.

       | Well, it's a simulation. You can also use your time and resources
       | to provide suitable plants for the bees in reality;
       | http://hummelgarten.ch/dokumente/ has been very useful to me;
       | there are tutorials and tables on how to best plant your green
       | spaces that the bees are well taken care of throughout the year;
       | this also works in the city.

       | I spent a few minutes looking at this "BEE-Steward" and it's
       | corresponding models, BEEHAVE and BEESCOUT, and the underlying
       | NetLogo language that is used to model these things.
       | 
       | I guess I immediately have a few questions - How do we know that
       | the model corresponds to reality at all? I mean, I know we have
       | experiments to confirm what impacts the bees, but it seems like
       | there could be a massive amount of variety depending on different
       | factors. I'd love to see some research showing that BEE-Steward
       | can work in real scenarios. Right now, they just have a
       | simulation showing "hey, if we change x and y we can get 5x more
       | bees", but does that actually correspond to reality?
       | 
       | Secondly, how do we make farmers actually _want_ to use this? Do
       | they get paid for taking care of bees on their land? I know this
       | is just a policy question, but it 's still important to answer.
       | Do farmers need any training to use this? Can we collect data in
       | an automated fashion to reduce the work the farmers have to do?
       | This almost sounds like a deep learning problem - use a camera to
       | map + classify areas of farmland, how many pollinators they have,
       | the presence of bees, etc.
       | 
       | Finally, what is the fundamental problem of bee modeling? Is it
       | fundamentally a computational problem (where we know the rules,
       | but computing the model can be hard) or is it a data problem
       | (where we know how to compute how the bees will behave, we can do
       | it efficiently, but coming up with rules that bees actually
       | follow is hard)? I've noted that the NetLogo environment by
       | default will only take up 1GB of RAM, which is already not very
       | much considering the JVM itself will take a pretty big chunk to
       | run just about anything.
       | 
       | It would be interesting to start building some sort of "National
       | bee model", rather than just working farmland by farmland. Is
       | there any project like this in the works?
       | 
       | Either way, I'm sure all of my questions and more are already
       | being asked/answered by people much more involved with the
       | conservationist field. Just my 2 cents.

         | Agreed. Allow me to be skeptical, but I find it hard to believe
         | that less than 4000 lines of NetLogo are going to accurately
         | model a system as complex as bee ecosystems.
         | 
         | I say this as someone who has spent _many_ years writing
         | ecosystem models for schools (some of them with NetLogo). _Toy_
         | models often require more than that to be useful.
         | 
         | You'll have a set of assumptions. You'll have a number of
         | formulae that you can individually say there is experimental
         | evidence they roughly models reality, if everything else is
         | held constant. But you almost certainly do _not_ have the
         | experimental evidence to say that when these six formulae are
         | interacting together, they will behave in known, deterministic
         | ways.
         | 
         | The paper does not appear to show any applications where
         | researchers were able to predict something novel using the
         | simulation, test it in the real world, and see how well it
         | matched the results. Their "results" (if I'm interpreting
         | correctly) appear to be mostly summarized in figure 3, which
         | seems to be created by trying different settings until the
         | model very, very roughly matched some historical dataset.
         | Someone correct me if I'm wrong.

         | In the U.K. at least, they do. The government pays you to leave
         | some part of your field unused and untouched. It's called
         | 'wilding' and it's well paid enough that the subsidy sometimes
         | is worth more than any reasonable crop that would grow on that
         | patch of land.
         | 
         | Jeremy Clarkson's Farm (of Top Gear fame) had a segment on
         | this. My take is that farming is a very subsidy-heavy business.
