Reforestation: There’s a drone for that
Drones, or technically UASs (unmanned aircraft systems), also sometimes called unmanned aerial vehicles (UAVs) represent a fast-growing and impactful manifestation of 4IR Tech in the physical world, especially agriculture. All the elements that culminate in making these remote-controlled aerial vehicles possible have their origin in some sort of new technology, from design and manufacturing to control and functionality.
Now one of the many uses of drones is their ability to assist in reforestation. DroneSeed is an American company in Seattle, Washington that specialises in high-tech drone reforestation technology capable of planting seeds six times faster than a human. Another drone reforestation company is the Canadian firm Flash Forest that specialises in drone reforestation for the recovery of forests damaged by wildfires.
Although drone seeding can deliver huge seed payloads quickly, successful planting from the sky also depends heavily on the seeds themselves, as a variety of factors can impact the actual initial germination rate from the dropped pods. Seeds must be pre-prepared for effectiveness once drone-planted. That’s why DroneSeed bought the seed company Silvaseed to assist with seed effectiveness and to increase seed availability for use by large aerial planting projects.
According to the article “Drones Can Reforest the Planet Faster Than Humans Can”, published by Forbes on 30 September 2020, “we haven’t been very successful in reforestation using humans alone, it’s just too slow”.
But drones can help. “Having the hard labour done by a drone accelerates the pace of reforestation by at least 10 times over having humans alone do the work. And two humans could potentially direct 10 of these drones, so the pace can be geometrically accelerated.”
This means the most effective answer to rapid reforestation is likely to be re-seeding from the sky, powered by 4IR Tech.
In South Africa, drones are also increasingly playing a crucial role in efficient agriculture and farming in general. Currently specialising in drone-based crop spraying, KwaZulu-Natal-based PACSys is a farmer-owned organisation established in 2016 to research, develop and distribute precision agricultural technologies, tailored to increase farming efficiencies and ultimately profits at all levels.
As these examples show, by increasingly using new technologies in recycling and reforestation efforts, they enter the mainstream through growing efficiencies to become widely used throughout industries, rather than remaining on the fringe. In turn, these efforts can lead to a real positive impact on alleviating climate change, effectively and economically.

Recycling and reforestation (18:00, 13 July 2022)
On the one hand, 4IR technologies are used extensively to assist in alleviating climate change through recycling, while at the same time, it’s also used to assist in effective reforestation. Recycling helps with climate change alleviation because less energy is used in the processing of materials and as less materials enter landfills as unused waste. Trees and plants help to remove harmful carbon dioxide from the atmosphere, while releasing oxygen. This results in a net positive effect on the environment. Reforestation introduces more natural greenery into the environment, increasing this positive result.

Weather and water (28 September 2022)
Climate change has a direct impact on weather changes because a warmer earth leads to ice caps melting and the ocean level rising, while floods and other severe weather patterns can lead to the disruption of agriculture and general living conditions. With 4IR technologies, the change in weather patterns can potentially be detected earlier so that alleviation measures can be implemented more timeously.
