“…Yu et al [34] showed that drought events has become ever more serious both in severity and in extent during the crop-growing season in recent decades over Northeast China. Moreover, wetlands have great sensitivity and vulnerability to the changes in water resources [26,35,36]. The warm-drying trend has contributed to considerable wetland degradation and agricultural hazards in Northeast China [37].…”

Assessment of the response of streamflow to future climate change in headwater areas is of a particular importance for sustainable water resources management in a large river basin. In this study, we investigated multiscale variation in hydroclimatic variables including streamflow, temperature, precipitation, and evapotranspiration in the Headwater Areas of the Nenjiang River Basin (HANR) in China's far northeast, which are sensitive to climate change. We analyzed 50-year-long records of the hydroclimatic variables using the ensemble empirical mode decomposition (EEMD) method to identify their inherent changing patterns and trends at the inter-annual and inter-decadal scales. We found that all these hydroclimatic variables showed a clear nonlinear process. At the inter-annual and inter-decadal scales, streamflow had a similar periodic changing pattern and transition years to that of precipitation; however, within a period, streamflow showed a close association with temperature and evapotranspiration. The findings indicate that the response of streamflow in headwater regions to climate change is a nonlinear dynamic process dictated by precipitation at the decadal scale and modified by temperature and evapotranspiration within a decade.

“…Varios autores han relacionado también el cambio de humedales con el cambio climático global reflejado en cambios de temperatura y precipitación (Zhang et al 2011, Jiang et al 2014, Wang et al 2014. Sin embargo, los datos climáticos para Colombia no indican que haya habido un cambio significativo de la temperatura media en las zonas rurales durante los años de los que se tiene registro.…”

“…Wetlands in the SRB have suffered from severe degradation, with an area deduction of 13.1% from 1975 to 2005 [41]. Climate change is considered as an important factor in the degradation of wetland in the SRB [24,42]. The warming and drying climate as well as the reduction in discharge in the basin would probably exacerbate the concern over wetland shrinkage and biodiversity loss in the river basin.…”

Abstract:The Songhua River Basin (SRB) in Northeast China is one of the areas most sensitive to global climate change because of its high-latitude location. In this study, we conducted a modeling assessment on the potential change of water resources in this region for the coming three decades using the Soil and Water Assessment Tool (SWAT). First, we calibrated and validated the model with historical streamflow records in this basin. Then, we applied the calibrated model for the period from 2020 to 2049 with the projected and downscaled climatic data under two emission scenarios (RCP 4.5 and RCP 8.5). The study results show: (1) The SWAT model performed very well for both the calibration and validation periods in the SRB; (2) The projected temperatures showed a steady, significant increase across the SRB under both scenarios, especially in two sub-basins, the Nenjiang River Basin (NRB) and the Lower SRB (LSRB). With regard to precipitation, both scenarios showed a decreasing trend in the NRB and LSRB but an increasing trend in the Upper Songhua River Basin (USRB); and (3), generally, the hydrologic modeling suggested a decreasing trend of streamflow for 2020-2049. Compared to baseline conditions , the streamflow in the NRB and LSRB would decrease by 20.3%-37.8%, while streamflow in the USRB would experience an increase of 9.68%-17.7%. These findings provide relevant insights into future surface water resources, and such information can be helpful for resource managers and policymakers to develop effective eco-environment management plans and strategies in the face of climate change.
