英文摘要 | Phosphorus (P) losses from fertilized croplands to inland water bodies cause serious environmental problems. During wet years, high precipitation disproportionately contributes to P losses. We combine simulations of a gridded crop model and outputs from a number of hydrological and climate models to assess global impacts of changes in precipitation regimes on P losses during the 21st century. Under the baseline climate during 1991-2010, median P losses are 2.7 +/- 0.5 kg P ha(-1) year(-1) over global croplands of four major crops, while during wet years, P losses are 3.6 +/- 0.7 kg P ha(-1) year(-1). By the end of this century, P losses in wet years would reach 4.2 +/- 1.0 (RCP2.6) and 4.7 +/- 1.3 (RCP8.5) kg P ha(-1) year(-1) due to increases in high annual precipitation alone. The increases in P losses are the highest (up to 200%) in the arid regions of Middle East, Central Asia, and northern Africa. Consequently, in three quarters of the world's river basins, representing about 40% of total global runoff and home up to 7 billion people, P dilution capacity of freshwater could be exceeded due to P losses from croplands by the end of this century. |
