Context: Positive feedback loop is a process where changing one quantity changes the second one, and the change in the second quantity, in turn, changes the first. Scientists fear a positive feedback loop may spiral the climate crisis out of control.
Desertification is an example of a positive feedback loop, just as the melting of the Arctic ice cap, thawing of the Siberian permafrost, and the large-scale release of methane from methane hydrate lying on the sea and ocean floors. The climate crisis is causing desertification and, in turn, desertification is exacerbating the crisis. The cycle continues.
To curb desertification, we need to restore degraded soil via forestry, improving vegetative cover, enhancing water use efficiency, reducing soil erosion and adopting better farming systems. All these will help enhance biomass production and organic carbon content in the soil. Combating desertification and climate change, thus, have the same solutions—enhance natural sinks.
What can be done?
Lastly, any global mechanism cannot depend solely on international funding. redd+ experience shows that once foreign funding ceases, projects become unsustainable. So, funds for the Sink Mechanism have to be a combination of domestic and international resources to build domestic ownership.
