Geography

Carbon Sequestration

The process of capturing and storing of carbon dioxide in soil and oceans, which has been released into the atmosphere

Land Degradation

Poor farming diminishes land

Biodiversity

The variety of life on Earth

Carbon cycle

process of exchanging carbon between biosphere, lithosphere, hydrosphere and atmosphere

Nutrient cycle

Exchange of organic and inorganic matter back into living matter

Carbon Sink

collection of carbon

Deserification

Human induced factors degrade land into arid areas

Biosphere 2

recreating earth’s ecological systems inside artificial habitat

Veolia

40% of sydney’s waste is buried underwater, releasing methane into pipes which provide electricity, and heat to grow barrumindi

mulch in veolia

The mulch is layered between waste for separation, the top layer rehabilitates the land (grows)

Muloon

Uses leaky weirs and contour intervals to slow the flow of water

Muloon strategy 2

inverted logs which push against water

Process of rebuilding land

Natural sequence farming rehydrates, intense cattle grazing gets rids of grass area is fertilised by poo, carbon is absorbed and improves soil quality.

Why is slowing the water good

it allows for there to be water reserves during climate change, and for it to slowly rebuild the land

Veolia Bio reactor

landfill inside bioreactor, releases methane that become electricity and grows fish via its byproduct of heat.

Muloon institute

features regenerative farming practices such as trees, contour intervals and leaky weirs to make the grass greener

Circular economy

eliminating waste, regenerating nature

Kelp forrest

underwater carbon sink

Why is carbon in the soil good

More carbon means better soil structure, higher water retention and less greenhouse gas effects from the atmosphere

why carbon sinks are important for climate stability?

They remove carbon from the atmosphere, reducing the effect of global warming

Contouring

Digging a a channel along a contours line to prevent erosion, stop gully widening, and trap valuable nutrients and sediments.

SDGS in veolia

Veolia contributes to 17 of them including Clean water and sanitation

bushfires and Great Barrier Reef bleaching

examples of environmental change
