1The current phosphate recycling situation in China and Germany:a comparative review显示文摘Phosphorus(P)is an indispensable element for organisms but the primary source of P-mineral phosphate resources-are non-renewable.Agricultural production has a high demand for fossil phosphate resources,but the resulting phosphate-rich residues are lack of management.This leads to rapid reserves depletion and severe phosphate pollution risks.One sustainable way is to reuse the phosphate dispersed in various residues such as sewage sludge and livestock manure.Diverse techniques have emerged to recover phosphate from wastes to close the phosphate cycle.While it is a global issue,the regional situations regarding potential phosphate scarcity and its management differ strongly.China is rich in phosphate resources,but over-exploitation has greatly increased the risk of phosphate rocks depletion,while in Germany the P resources depend on imports,but there is commitment to keep a balance between import and utilization.This had led to great differences in the way the two countries deal with the're-use'of phosphate in waste.China is now in a transition phase from the simple terminal pollution control to'waste'reuse and nutrient resources recycling.One sign of this tendency is the mandatory garbage classification and preparation for further processing and recycling.This was first implemented in Shanghai in 2019,whereas Germany has been following the legal framework for waste management since the 19 th century.There are a series of laws to control the nutrient loss from municipal and agricultural activities,as for instance with sewage sludge ordinance and fertilizer legislation.Many of these laws have been newly revised recently.Sewage sludge cannot be directly utilized on farmland as organic fertilizer any more.Alternatively,phosphate and other nutrients should be recovered from sewage sludge.Advanced phosphate recovery technologies and related nutrient recycling schemes are proceeding.This review summarizes the current situation of phosphate-containing residues management and phosphate reuse in China and Germany.The state legislation and policies,which would affect the phosphate recycling concept are presented as well.As there are various kinds of phosphate-containing residues,different phosphate recovery technologies can be applied.Those technologies are discussed from their mechanism and suitability.Qing XUE Xinyue HE Saskia D.SACHS Gero C.BECKER Tao ZHANG Andrea KRUSE 2019Frontiers of Agricultural Science and Engineering2019,6,4:1

3新世纪展望显示文摘21世纪的“新世界秩序”承诺要共同繁荣……也包括全球冲突的危险。这是这个时代的悖论。人类社会的规模(人口、经济产量、资源利用以及生产网遍及全球)既激起了巨大希望,也引发了超级挑战。国家管理和经济学的旧模式已经不够敷用。我们这一代挑战的解决方案需要史无前例的全球合作,但很少有人觉察到这种需要,美国和其他地方的政治精英和知识分子还在热烈争论这个问题。杰弗雷·萨克斯(Jeffrey D.Sachs) 张子(译) 2009国外社会科学文摘2009,,1:0
4重新思考全球货币供应显示文摘2009年3月,中国人民银行提出一套新的全球金融财务安排政策,国际金融界为之震惊。这个提议之所以备受瞩目,很大一部分原因是,它反映了中国国际经济实力的提高,然而,提议本身也值得探讨一番。杰弗里·D·萨克斯(Jeffrey D.Sachs) 红猪(翻译) 2009环球科学2009,,7:0

6Stagflation is Back显示文摘Conventional oil supplies will remain tight in the years ahead.New discoveries will not suffice.World crude-oil production nearly tripled in 1960-73 (from 21 million barrels a day to 56 million), but has grown a mere 30% since then, to around 73 million barrels per day in 2006. In fact,Persian Gulf crude-oil production stopped growing entirely after 1974,Jeffrey D.Sachs 2008国际经济合作2008,,9:0
7滞涨重新出现 下面讲讲如何战胜它显示文摘今后,传统的石油供应将继续趋紧。新发现的石油还不能满足需求。世界原油产量在1960年至1973年期间增加了近两倍(从日产2100万桶增加到5600万桶),但是从那以后其增幅仅为30%,2006年的日产量在7300万桶左右。事实上,在1974年之后,波斯湾的原油生产完全停止增长,最高的日产量在2100万桶左右。中东地区以外的石油发现以及产量增长的进展都很缓慢,Jeffrey D.Sachs 张言 2008国际经济合作2008,,11:0
8应对气候变化需要全球协同显示文摘当步入波兰卡托维兹气候大会的会场时,我看到一个视频,正在展示公众可以采取哪些行动以应对气候变化。视频中提到的方案包括随手关灯、用步行代替开车等等,旨在号召每一个人都采取行动,去应对人类生活所引致的气候变化。杰夫瑞·萨克斯(Jeffrey D.Sachs) 2019能源评论2019,0,1:0
910个改变世界的想法(下)显示文摘想法之六:地球工程 我将告诉你一件我本不该说的事情:我们可能不能阻止全球变暖。北极地区2007年创纪录的融化速度警告我们,按照现有状况推断,到2013年夏天最后一块冰就会消失。我们要进行的首要任务是控制全球温室效应,但是经过《京都协议书》签署后这十几年时间的验证,我们失败了。杰弗里·D.萨彻斯(Jeffrey D.Sachs) 樊慧慧(译) 2008国外社会科学文摘2008,,10:0
10THE CRITICAL CLIMATE AGENDA显示文摘The world set a goal in the Paris Agreement:to keep global warming within 1.5 degrees Celsius of preindustrial levels.The Intergovernmental Panel on Climate Change has explained why this is a valid goal.If global warming were to go higher than 1.5 degrees Celsius,this would jeopardize life on the planet with a potential multi-meter sea-level rise,the collapse of critical ecosystems,and the release of methane from thawing permafrost,possibly triggering runaway warming.Yet the world's current trajectory implies a catastrophic 2.7-degree-Celsius increase in global temperature.Jeffrey D.Sachs 2021Beijing Review2021,64,45:0
