You need to have some formal systems analysis done, to confirm/refute this speculation.
Industrial as that might sound, its actually a very effective way to analyse nature as well as industrial systems, the system of humanity, all their interactions with nature, and how we need to integrate with nature.
As a Systems Engineer myself, with some experience of doing this now, I can tell you straight-off, that "Renewables" is deeply flawed, the only one within the bunch that we should be pursuing is solar.
The fundamental problem on the planet is that we have exhausted the "Indigenous" energy of the planet.
That is the energy of all life, not just as fossil fuels, and by exhausted, I mean what we can use of it, extracting it by profit.
As availabilty of it depletes, difficulty of obtaining it has to increase, and this has to knock-on to all business for profit, impacting all margins, forcing all businesses into criminal practices to remain profitable.
The way we use money issued as debt then has to be questioned, because this is what starts out as a requisition to extract, therefore a requisition to do damage.
Money is abstracted energy, always physically, energy quantifies what can be done with money, the energy value of money is clear in markets in terms of kWhrs.
Solar is the antidote to the problem of Indigenous energy depletion, solar is how we must replace it.
We might say our real challenge is to replace the original Indigenous energy with an artificial version of it, but who is to say this isn't nature at work?
Anyhow I could go on, I only scratched the surface here, to show a little of what needs to be done to understand the truth, and the only solution - solar.
So your question might more appropriately be, what would the impact of only solar be, on those landslides?
Notice also the current misbelief that massive lithium mining needs to be done to back up all energy using lithium is rubbish because we can do with hydrogen, actually must do with hydrogen for many reasons, not least to keep planes in the air, whilst reversing the environmental effect of those too, from negative to positive.
I hope this helps, but you really need to either get equipped with the systems Engineering skills to do yourself, or get someone with those skills to assist. ChatGPT knows it all too. It's also an invaluable assistance.
