According to GP:
>> Chinese mainland reforestation programme plan was 4 mln ha/year 20 years ago.
>> So, drones can plant, say pine seedlings with density of 4 thousand/ha (which is IMHO insufficient), which gives capacity of just 9 ha/day
Suppose 180 working days a year that would give:
4 * 10^6 / (180 * 9/2) ~= 5000 operators
That doesn't actually sound too bad, not sure how many drones per operator are counted for in the 36,000 trees per 2 operators with multiple drone numbers.
One a side note this could still be well above the cost of human labor in third-world countries.
- ommunist 11y agoThank you hurin, this is a good point. There are marginal costs however. Traditional planting sword is unbreakable. Drones are not. ПЛА-1 was widely criticised in the USSR for its cassette's low quality, and often failures (this is why ПЛА-1А was designed). The other thing is that drones offer only pre-germinated seedling as planting material. This goes well with light seedlings like pine and spruce. But how many oak acorns can be loaded? What about ultra-light seeds, like birch? What about tropical species? The technology is promising, but it will take at least 20 years for it to make its way to industrial forestry with trial and error. I myself would appreciate to see planting drones pack in every forestry range in Russia (with their ZALA UAV they can do that). But I am afraid this particular one is more of a hoax to cover some scheme behind trading carbon quotas, than a real thing. I would like to think otherwise, but years in the industry made me cynical. I am deeply sorry about that.
