Stakes or landscaping staples hold it in place, and sometimes seams are sealed with additional material (if the barrier is for weedblocking).  It is commonly seen in industrial settings (areas around factories), and in public areas around roads and other transportation infrastructure where people don’t walk. this is a permanent landcover, not temporary covering for construction, etc.

Different things ;

erosion control,

weed block.

The weed block plastic here is called 'weed mat', it is designed so as not to allow sunlight through, well not enough for a plant to grow.

On a steep slope it will do nothing for erosion control as it sits above the soil. I have a few square meters of it at home.

Erosion control may well allow enough sunlight through to enable plants to grow .. including weeds.
