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).
Chioma Blaise Chikere, 2017 second prize winner of the Green Sustainable Chemistry Challenge
In 2017, Chioma Blaise Chikere was awarded the second prize of the Green and Sustainable Chemistry Challenge. Her project “Eco-restoration of crude oil-polluted land in Nigeria” demonstrated how organic nutrients such as garden fertilizers and animal excreta can be used to degrade hydrocarbons, cleaning up the soils heavily contaminated by decades of oil spills and advancing SDGs 6, 13 and 15. Three years later, we caught up with Dr. Chikere to learn about her research journey.
The need for improved and safely managed sanitation facilities is acute in dense informal settlements in rapidly urbanizing areas. One of the key factors influencing the cost-effectiveness and reliability of service provision in informal settlements is the ability to optimize waste collection from latrines with variable use patterns that are spatially dispersed within an informal settlement. This study investigates how latrine sensors could be used to estimate waste fill levels and improve servicing efficiency for forty latrines in Nairobi, Kenya, supporting SDGs 3, 6 and 9.
The abundance of residual colors in the effluents discharged from textiles, tanneries, dyeing, food processing and numerous other industries across the globe, currently poses a grave threat to global environmental sustainability. Polymer enhanced ultrafiltration (PEUF) can be a cost effective and energy-efficient membrane separation process in the treatment of wastewater. This article supports SDGs 6, 12 and 14.
Mercury contamination in soil, water and air is associated with potential toxicity to humans and ecosystems.

This special issue of World Development is part of the SDG Perspectives Series, a collaborative, interdisciplinary endeavour whose aim is to interrogate the gap between academic and policy discourses underpinning the 2030 Sustainable Development Agenda. The articles offer rich overviews on key goals, and provide examples, research evidence, and empirical data that illustrate important challenges and new lines of enquiry. By narrowing down the discussion on specific aspects of the SDGs that deserve particular attention, the special issue offers a nuanced perspective on the potential and limitations of the 2030 Agenda.
This book chapter advances SDG 3 and 6 by discussing decontamination of water supply and prevention/treatment of waterborne microorganism transmission in healthcare settings.
The #SDGBookClub helps children learn about the Sustainable Development Goals. The book club presents a selection of books for children aged 5-12 on each of the goals. Check out the books that have been selected in support of Goal 6 - Clean Water and Sanitation.

This paper contributes to the debate on the agency of the South in shaping global norms by focusing on the adoption of sustainable development as the consensus framework for the SDGs. Based on documentary and archival research, interviews with stakeholders, and direct participant observation of the SDG negotiations and consultations, the paper chronicles the ideas originating from the South in the emergence and subsequent evolution of the sustainable development concept and the adoption of the SDG.
