toxic monoculture neighbors

i posted this in the homestead section but no replies so am hoping i get some here. thanks:

hello, newbie forumer here.

i just bought a 5 acre property that will be turned to a permie demo farm in the philippines. my neighbors on two sides (plus one across the road) are monoculture banana farmers who use chemical farming techniques. i need advice on how to lessen toxic contamination on my side, and prevent the inevitable pest plagues from coming over to my side of the land. is this a big problem? i hope i can still make a go of being a permie there. i didn't consider my neighbor's properties before i bought. otherwise i just blew a huge part of my seedcorn. the one above me particularly bothers me as they are upslope of us and we're in a mountain slope. any water i get from runoff most likely will be contaminated. so retention ponds might be out of the question.

my ideas (don't know if advisable): build high hugelkultur beds as barriers, plant lots of high shrubbery and leafy trees to block off chemical sprays, put lots of chemical eating mycela/mushrooms in strategic places, etc.

thanks for any advice or personal experiences!!

This reply is based on theory so are it with a grain of salt, but were I in your shoes I would do the fallowing.

Plant bamboo. That's right find the tallest variety I could and make a wall of bamboo between me and them. Several reasons. First bamboo absorbs alot of water so maybe it could filter out some of that gunk. 2nd, it grows pretty darn fast, thereby allowing a quick wall between you two. Third, it can be used for on site construction.

Again just theory, but thought I would chime in.
