Ecosystem Services Assessment and Valuation of Atmospheric Magnesium Deposition

摘要: Ecosystem services (ES) often rely on biogeochemical cycles, but values associated with abiotic are ignored or underestimated. from atmospheric magnesium (Mg2+) deposition flows (wet, dry, and total), which can be considered a source of naturally-occurring fertilizer liming material, have not been included in economic valuations ecosystem services. Market-based valuation these service partially address this negative externality. This study assessed the value wet, total contiguous United States (USA) within boundary-based administrative accounts (e.g., state, region) based data National Atmospheric Deposition Program (NRSP-3), market price human-derived material (agricultural dolomite, CaMg(CO3)2). The supporting was $46.7M (i.e., 46.7 million U.S. dollars) ($18.5M wet + $28.2M dry) an average 2014 $12.90 per ton agricultural dolomite (CaMg(CO3)2). atmosphere is common-pool resource that plays important role pedosphere, providing ES, its monetary identified due to lack information and/or knowledge proper method. demonstrates one approach translate entering soil as ES potential at various scales. Omission analysis lead incomplete valuation.
