What is the main ecological risk of converting land to cropland despite productivity gains?
|
Loss of carbon sinks and soil degradation |
|
When the soil is disturbed, such as being truned into a cropland, it releases carbon that were stored in the soil, it is one of the main ecological risk of converting land into cropland. |
Soil stores the largest amount of terrestrial carbon, roughly three times more carbon than terrestrial biomass and double the amount of atmospheric carbon [24]. Agricultural soils, particularly croplands, are often lower in carbon than soils under native vegetation like forests [25] ( From the study ) |
