Land Use

There are two means to radically reduce the level of greenhouse gas concentrations in the atmosphere. Firstly, we can decrease human- induced emissions, secondly, we can move to widespread adoption of proven land and ocean practices that sequester carbon from the air and store for decades or even centuries. Recent research in the United States has suggested that widespread implementation of regenerative practices worldwide could have a significant impact, storing as much as eight billion tonnes of carbon per year over the long-term, or nearly as much as current annual emissions from burning of fossil fuels.

There are roughly 3 trillion trees, 15 billion are cut down every year. Protecting 690 million acres of forest could avoid carbon emissions of 6.2 gigatons by 2050. This would bring the total forest area to 2.3 billion acres and secure the protection of 895 gigatons of carbon dioxide.

In places like the Amazon, burning continues to be the predominant means of clearing land for cattle farming. Up to 750 million acres of degraded lands in the tropics could be restored. If 450 million acres were restored by 2050, this would sequester 1.4 tons of carbon dioxide annually or 61.2 gigatons of CO2 by 2050.

Presently, Bamboo is planted on roughly 80 million acres. Assuming it can be grown on an additional 37 million acres of degraded land this could avoid 7.2 gigatones of emissions by 2050. This does not include the potential for bamboo to be subsituted for concrete, plastics, aluminium or steel.
