Sustainable Development, EarlyView.ABSTRACT Modern industrial agriculture is predicated largely on the production and utilization of chemical fertilizers. Although this approach has played an integral role in increasing food security in many parts of the world, the long‐term sustainability of this resource‐intensive approach is questionable.

Demand‐Driven Location of Repair Activities and the Local Distribution of the Circular Economy
Sustainable Development, EarlyView.ABSTRACT This paper explores the territorial embeddedness of repair at the local and regional level, which is part of the relatively understudied regional circular economy. This study involves the analysis of the dispersion of repair employment compared to other economic sectors as well as the degree of connection of repair activities to other economic

Jingshui jishu【目的】目前，我国已经形成了深度脱水-填埋、好氧发酵-土地利用、厌氧消化-土地利用、干化焚烧-建材利用这4条主流的市政污泥处理处置工艺路线，每种工艺路线都有各自的优缺点和适用条件，但每种路线的碳排放水平尚不明确，致使碳排放难以作为工艺比选测算指标落地应用。【方法】根据联合国政府间气候变化专门委员会指南，采用排放因子法，在确定核算边界后，全面核算了污泥从污水处理厂外运直至最终消纳的全流程碳排放量，包括处理处置过程中因甲烷(CH 4)和一氧化二氮(N 2O ...

How Brazilian Public Universities Are Operationalizing The SDGs: Strategic Plans Analysis
Sustainable Development, EarlyView.ABSTRACT Despite the importance of universities for Sustainable Development, only a handful of studies have evaluated the implementation levels of SDGs in HEIs in Latin America. To fill this void, this study examines the strategic plans of 70 Brazilian public universities, which account for 92.8% of Federal Universities.

Sustainable Development, EarlyView.ABSTRACT Sustainability represents a complex issue in which scientific knowledge inevitably coexists with the subjective perception of humans in its turn influenced by civilization, cultural but also unconscious aspects. These results emerge with evidence from a critical analysis of the main definitions of sustainability delivered by credited entities (

“One Water”理念下南方多雨地区分流制污水管网提升改造思路
Jingshui jishu【目的】本文围绕“改善污水管网质量、提高污水处理厂进水浓度、改善城市水环境”的目标，针对南方多雨地区A城市水环境质量差的现象，分析得出主要问题是污水系统不健康。【方法】同时通过数据分析、水质调查、污水溯源、闭路电视(CCTV)管道内窥检测、水力模型模拟等方法分析了造成问题的主要成因：污水管网整体质量差、雨污混接明显，城市内涝导致涝水进入污水系统，污水管网的良好运维机制尚未建立等。【结果】提出了全域整治、雨污统筹、顶层保障等系统性对策，通过增加污水泵站降低末端污水管道埋深 ...

Affordable and Clean Energy: CO2 Emissions, Resilience and Inequality
Sustainable Development, EarlyView.ABSTRACT Sustainable development means building the resilience of both people and the planet. It includes implementing strategies which reduce emissions while also enabling more vulnerable households to transition to clean and affordable energy. This paper examines household CO2 emissions in Ireland to highlight those who emit most and least in key ...
