| 1 | Environmental Sustainability of Water Footprint in China' Mainland显示文摘Water footprint(WF)measures human appropriation of water resources for consumptive use of surface and ground water(blue WF)and soil water(green WF)and for assimilating polluted water(grey WF).Questions have been often asked about the exact meaning behind the numbers from WF accounting.However,to date environmental sustainability of WF has never been assessed at the sub-national level over time.This study evaluated the environmental sustainability of blue,green and grey WF for China’s 31 mainland provinces in 2002,2007 and 2012,and identified the unsustainable hotspots.Overall,the total WF increased by 30%between 2002 and 2012.The growth can be attributed to the increase of grey WF because the green and blue WF showed only a slight rise.Among all provinces investigated in 2012,eleven showed unsustainable blue WF(sustainability index SI<0),which were mainly located in the North China Plain.There were 12 provinces that displayed unsustainable green WF,and they were distributed in China’s southern and southeastern areas.The grey WF was not sustainable in approximately two third of provinces(19),which were mainly located in China’s middle and northern regions and Guangdong province.More than half of China’s provinces showed trends of improved SI of green and blue WF from 2002 to 2012.However,the SI of grey WF decreased in almost two third of provinces.Poor levels of WF sustainability were due to water scarcity and pollution,which intensify the degradation of local rivers and ecosystems and make restoration more difficult.The results shed light on the policy making needed to improve sustainable water management,and ecological restoration of hotspot regions. | Junguo Liu Dandan Zhao Ganquan Mao Wenhui Cui He Chena Hong Yang | 2020 | Geography and Sustainability2020，1，1： | 1 |
| 2 | Past and Future Changes in Climate and Water Resources in the Lancang–Mekong River Basin: Current Understanding and Future Research Directions显示文摘The Lancang–Mekong River(LMR)is an important transboundary river that originates from the Qinghai–Tibet Plateau,China and flows through six nations before draining into the South China Sea.Knowledge about the past and future changes in climate and water for this basin is critical in order to support regio-nal sustainable development.This paper presents a comprehensive review of the scientific progress that has been made in understanding the changing climate and water systems,and discusses outstanding challenges and future research opportunities.The existing literature suggests that:①The warming rate in the Lancang–Mekong River Basin(LMRB)is higher than the mean global warming rate,and it is higher in its upper portion,the Lancang River Basin(LRB),than in its lower portion,the Mekong River Basin(MRB);②historical precipitation has increased over the LMRB,particularly from 1981 to 2010,as the wet season became wetter in the entire basin,while the dry season became wetter in the LRB but drier in the MRB;③in the past,streamflow increased in the LRB but slightly decreased in the MRB,and increases in streamflow are projected for the future in the LMRB;and④historical streamflow increased in the dry season but decreased in the wet season from 1960 to 2010,while a slight increase is projected during the wet season.Four research directions are identified as follows:①investigation of the impacts of dams on river flow and local communities;②implementation of a novel water–energy–food–ecology(WEFE)nexus;③integration of groundwater and human health management with water resource assessment and management;and④strengthening of transboundary collaboration in order to address sustainable development goals(SDGs). | Junguo Liu Deliang Chen Ganquan Mao Masoud Irannezhad Yadu Pokhrel | 2022 | Engineering2022，8，6： | 0 |
