I only remember a segment on Democracy Now: https://youtu.be/AqyHzePx3ew?t=440. It must have been an article instead (EDIT: This one: El Salvador’s ‘cool dictator’ boasts country would be ‘a one-party system’ after election win)

But they also reported on the "civil war" where many poor people seem to have been unjustly arrested: https://youtu.be/A4Cw0KtkzWg https://youtu.be/fvDFFRA6HmI.
I believe / suspect that robotics could help reduce pesticide and herbicide use. There are many examples of "high intensity agriculture" or a more traditional hands on agriculture can have higher yields.
There are now robots that use computer vision to see herbs and then just push them back into the earth. Basically just robotic weeding. I'm sure you could do something similar with insects and pests with an "robotic rat catcher".
Ideally those robotic designs would be open source and easy to build and maintain with something like 3D printing.
