The vicious cycle of depletion
Riccardo Pravettoni, UNEP/GRID-Arendal
Agricultural systems in the temperate zone tend to occupy
fertile soils that would have formerly supported temperate
grassland or forest. Land clearance for croplands and pasture
has greatly reduced above ground carbon stocks from their
original state and soil carbon stocks are also often depleted as tillage disrupts the soil, opening it to decomposer organisms
and generating aerobic conditions that stimulate respiration
and release of carbon dioxide.
