Since Renaissance, the natural ecosystems have fallen into a complete state ofdisarray due to the rise in the amount of carbon dioxide. Soil, the unsparing stuff, is one of themajor sources of carbon storage, and plays a paramount role in the global equilibrium ofcarbon as well as carbon sequestration. Given that Iran is benefiting from vast steppes, therate of carbon sequestration in them dese...

The United Nations defines desertification as the loss of productivity in arid and semiarid environments. extended steppes Patagonia harbor small meadows whose compounded area is comparatively small, but their aboveground net primary production (ANPP) up to ten times higher than surroundings. These then represent a key ecosystem for cattle grazing systems, there are no descriptions trends ANPP ...

During the Last Glacial Maximum (LGM, 30 to 16.5 ka ago), Great Adriatic-Po Region (GAPR) was deeply affected by spread of glaciers from Alps southern foreland and dropping sea level ~ -120 m amsl. The combination these two events triggered aggradation Po Plain (GPP), a vast flat area between Alpine chain, Italian Peninsula north-western Balkan Peninsula, physically ecologically featured throug...

Satellite observations identify the Mongolian steppes as a hotspot of global biomass reduction, the extent of which is comparable with tropical rainforest deforestation. To conserve or restore these grasslands, the relative contributions of climate and human activities to degradation need to be understood. Here we use a recently developed 21-year (1988-2008) record of satellite based vegetation...
