Soil aggregation and aggregate-associated carbon play a vital role in soil integrity and C sequestration. The diversity of AMF land in fallow land was higher than cropland and increased with increasing mean annual temperature and mean annual precipitation. At HLJ, JL, and LN study sites, respectively, the soil aggregated organic carbon equivalent of soil aggregate organic carbon was 16. 8, 18. 6, and 13. 8% higher under fallow land, and 13. 8% higher under cropland. AMF diversity, network complexity, and their unexplained GRSP mediate the effects of CC and LUC on C-GRSP and aggregate-associated SOC, according to a structural equation model and random forest regression. This paper clarifies the climate sensitivity of C within GRSP and soil aggregates that respond in a synchrony with LUC, and it highlights the potential role of AMF in C sequestration and climate change mitigation.

This paper explores the effects of Municipal Solid Waste Management on Climate Change's ability by investigating, analyzing, and analyzing the consequences. The study was carried out by a Greenhouse Gas GHG inventory and determining the past and future Methane Gas emissions created from Askar Landfill in Bahrain's Askar Landfill. Methane gas emissions from Askar Landfill reached 25 million tonnes or 106 thousand tons MTCE, of which ten thousand tons MTCE were detained within the landfill but 90 thousand tons were released into the atmosphere. In 2008, production of methane gas reached 98 million m3 and 69 thousand tonnes, or 408 thousand tons MTCE, of which more than 40 thousand tonnes were discharged outside the landfill and 370 thousand tonnes were discharged outside the landfill. From the above, it is clear that MSW sanitary landfills, while being identified as important sources of GHG emissions, especially methane, contribute to global warming, are at the same time carbon storage vaults of some fractions of GHG resulting from the decomposing MSW body as well as the recalcitrant organic portions. The potential of carbon storage and sequestration at MSW landfills can be estimated at around 10% of the total amount of biogas produced.
