Working with Nature to mitigate climate change

Nature is one mighty powerful resource.

What if we could just harness that power, nature could be a powerful ally to mitigate climate change. Well, we can. By working with nature, not against it. Sounds pretty common sense right? That’s where Natural Climate Solutions come in.

Natural Climate Solutions (or Nature Based Solutions) basically mean helping nature do what she’s been doing for billions of years; sequester and store Carbon and GHGs.

Natural Climate Solutions involve conserving, restoring and improving land use and ecosystems.

NCS or NBS: “Actions to protect, sustainably manage, and restore natural or modified ecosystems, which address societal challenges effectively and adaptively, simultaneously providing human well-being and biodiversity benefits.” — IUCN

Did you know that grasslands soak up and store carbon in their roots and the soil? In total, they store up to 20% of soil carbon. But we often don’t see the value, and clear the land for housing and agriculture.

And that lovely green grass we have at home? From a biological perspective, that’s degraded grassland — as it’s only one species. So why not throw around some seedbombs on that lawn, make it more wild? Your lawn will be storing more carbon, and you can enjoy some lovely flowers and herbs!

Freshwater wetlands cover less than 5% of the world’s land area, but store vast quantities of carbon per hectare in the form of peat soils.

Peat soil: the surface organic layer of a soil that consists of partially decomposed organic matter, derived mostly from plant material, which has accumulated under conditions of waterlogging, oxygen deficiency, high acidity and nutrient deficiency.

Interestingly enough, the protection of marshes and peat bogs are a more effective long-term carbon store than forests. It is estimated that 760,000 hectares of peatlands are lost globally each year, mostly to be cleared and drained for palm oil production.

When the soil is drained, it releases carbon, which adds to climate change. But with draining, the soil also decreases in volume. And once the volume is down to sea level, the area is at risk of flooding, with huge consequences for all species, including humans, that live there as well.

Trees and forests continue to amaze us. They store carbon, provide us oxygen, are part of the meteorological system and so much more.

What happened? How did we lose all those trees? Well, we cut them down for wood, and to make space for housing, cities, and farmland to grow food.

Deforestation: The permanent removal of trees to make room for something besides forest.

Our population is expanding, and in combination with our consumption patterns, this puts pressure on clearing more land.

Deforestation is often pointed out as one of the major causes of the increasing greenhouse effects. This increase happens because of two reasons. The burning or decomposing of wood releases long trapped CO2 back into the atmosphere; and secondly, trees that are cut down are no longer capable of trapping CO2 from the atmosphere.

One of the more popular and well-known Nature Based Solutions is planting trees. Not surprising, because it’s such a tangible and likable option!

Technically, planting trees comes in two forms: reforestation and afforestation.

Reforestation: Planting new trees in areas where they have been removed, cut down, or destroyed by fire, disease, etc.

Afforestation: Planting trees on lands which, historically, have not contained forests.” — IPCC

Remember back in the old days (well, ok, we don’t actually remember) people used to gather nuts and berries? We don’t do that anymore, but a lot of our food does come from trees. Simply put, agroforestry is combining agriculture and trees.

Agroforestry: The interaction of agriculture and trees, including the agricultural use of trees.

With modern monocropping agricultural practices, we’ve taken apart the ecosystem in the name of efficiency, but mixing them brings back a lot of additional benefits.

In one part it’s to directly farm them for food, but also think of the other interactions trees have with the landscape: they can provide shade for other crops and animals, and prevent soil erosion and water evaporation.

And this leads us into the final category; agricultural lands. Because although a lot of attention goes to forests and trees; improving soil health through regenerative agriculture and land management practices is another key solution. So much so, it will have it’s own Jargon Buster!

Until then — Happy Sprinting!
