A comprehensive life cycle water analysis framework for residential buildings

Most studies on the environmental performance of buildings focus on energy demand and associated greenhouse gas emissions. They often neglect to consider the range of other resource demands and environmental impacts associated with buildings, including water. Studies that assess water use in buildings typically consider only operational water, which excludes the embodied water in building materials or the water associated with the mobility of building occupants. A new framework is presented that quantifies water requirements at the building scale (i.e. the embodied and operational water of the building as well as its maintenance and refurbishment) and at the city scale (i.e. the embodied water of nearby infrastructures such as roads, gas distribution and others) and the transport-related indirect water use of building occupants. A case study house located in Melbourne, Australia, is analysed using the new framework. The results show that each of the embodied, operational and transport requirements is nearly equally important. By integrating these three water requirements, the developed framework provides architects, building designers, planners and decision-makers with a powerful means to understand and effectively reduce the overall water use and associated environmental impacts of residential buildings.

Participatory filmmaking with Qur’anic students in Kano, Nigeria: ‘speak good about us or keep quiet!’

‘Participatory’ research is often presented as a means to ‘empower’ stigmatised groups by addressing shame and by promoting attitude changes. Drawing on experiences producing a ‘participatory’ docudrama with traditional Qur’anic students (almajirai) in Kano, northern Nigeria, I reflect on the limits of ‘participatory’ research as a tool for ‘empowerment’. I describe the risks stigmatised groups may incur by participating, and consider to what extent, if at all, it can foster social change. The almajirai have attracted negative attention as presumed victims of child neglect and as ‘cannon fodder’ for Islamic radicalisation. Their participation in the filmmaking gave them an opportunity to voice their concerns and to rebuke those treating them heedlessly. At the same time, they became vulnerable to accusations and suspicions within their communities. To escape the negative connotations of poverty, they deemphasised its role for almajiri enrolment, thus concealing structural inequalities.
