Forests in the tropics account for about half the above-ground carbon on Earth and as the trees grow older they are capable of storing more and more. In fact, their carbon-storing potential is so large that they are increasingly being viewed as a means of mitigating climate change. Take, for example, the United Nations effort to reduce degradation and deforestation by assigning value to forest car ...[Read More]
Imaggeo on Mondays: A fly by some fantastic farming
This week’s Imaggeo on Mondays is brought to you by Kristof Van Oost, a scientist from the Georges Lemaître Centre for Earth and Climate Research (UCL) in Belgium. He tells us how local organic farms are being managed to ensure a lot of carbon stays in the soil… This is a picture of the organic farm Het Open Veld in Leuven, Belgium. The farm is built around an alternative agriculture model in whic ...[Read More]
Imaggeo on Mondays: How sea urchins can help mitigate climate change
This week’s Imaggeo on Mondays stars the humble sea urchin – a creature suffering from the effects of climate change, but one that could also provide a way to sequester some of the CO2 responsible… Carbon dioxide and water react to form carbonic acid – a mixture of bicarbonate and hydrogen ions. Sea urchins bag the bicarbonate to grow bigger, stronger shells, or ‘tests’, but without a catalyst, th ...[Read More]
Imaggeo on Mondays: Long live the lichen!
Lichens are amazing organisms. They are a composite of algae and fungi, each of which supports the other through the exchange of nutrients (fungi to algae) and carbon (algae to fungi). They are also capable of making a home out of seemingly inhospitable rock surfaces – and what’s more – making the most of these surfaces to release the nutrients they need to grow. The quartzite above is home to the ...[Read More]
