Seth Itzkan of Planet-TECH discusses how holistic management can restore
grass lands and reverse the effects of climate change in his TEDx talk; “How
global warming can be mitigated through holistic management”.
In the video, Seth discusses his
experiences in Zimbabwe and how the village herders have changed the way they
manage their livestock. Using holistic management, they have replenished grasslands
and during the dry season surface water is occurring further upstream than before.
Increased availability of surface water has made farming easier and removed the
need for water pumps, saving money. Regenerating grasslands also increases soil
sequestration, reducing the amount of carbon in the atmosphere.
Holistic management uses livestock in a
way that mimics wild herds which were a key component in the ecosystem when
grasslands thrived. The wild herds would graze, naturally process the grass, fertilise
the ground and then move onto a new area. The villagers are now replicating
this process by running livestock in dense packs and moving them regularly just
as a wild herd would. They also stick to grazing plans to prevent over grazing.
Although his focus is on environments
that have suffered desertification (the transformation of habitable land to
desert), parallels can be made between the framework of holistic management and
the way farmers in New Zealand manage their stock. Relative to farmers in
Africa though, New Zealand farmers have lower emissions per unit of production and
are more efficient. However, even in New Zealand many farmers can apply management
strategies other farmers are already using to reduce their environmental impact.
A recent Motu working paper,
looks at such mitigation possibilities.
Holistic management was a way of
managing resources originally developed by Allan Savory. Here Allan offers
further discussion on holistic management and “how to fight desertification and
reverse climate change”.
