Socio-environmental consideration of phosphorus flows in the Urban Sanitation chain of contrasting cities
Regional Environmental Change, 2018Co-Authors: Geneviève S. Metson, Steve M. Powers, Jesse S. Sayles, Gunilla Öberg, Graham K. Macdonald, Nathaniel P. Springer, Anthony J. Weatherley, Yusuke Kuwayama, Rebecca L. Hale, Kelly L. HondulaAbstract:Understanding how cities can transform organic waste into a valuable resource is critical to Urban sustainability. The capture and recycling of phosphorus (P), and other essential nutrients, from human excreta is particularly important as an alternative organic fertilizer source for agriculture. However, the complex set of socio-environmental factors influencing Urban human excreta management is not yet sufficiently integrated into sustainable P research. Here, we synthesize information about the pathways P can take through Urban Sanitation systems along with barriers and facilitators to P recycling across cities. We examine five case study cities by using a Sanitation chains approach: Accra, Ghana; Buenos Aires, Argentina; Beijing, China; Baltimore, USA; and London, England. Our cross-city comparison shows that London and Baltimore recycle a larger percentage of P from human excreta back to agricultural lands than other cities, and that there is a large diversity in socio-environmental factors that affect the patterns of recycling observed across cities. Our research highlights conditions that may be “necessary but not sufficient” for P recycling, including access to capital resources. Path dependencies of large Sanitation infrastructure investments in the Global North contrast with rapidly Urbanizing cities in the Global South, which present opportunities for alternative Sanitation development pathways. Understanding such city-specific social and environmental barriers to P recycling options could help address multiple interacting societal objectives related to Sanitation and provide options for satisfying global agricultural nutrient demand.

Comparing Urban Sanitation and solid waste management in East African metropolises: The role of civil society organizations
Cities, 2013Co-Authors: J. Tukahirwa, Arthur P.j. Mol, Peter OosterveerAbstract:Sanitation and solid waste management systems have recently received major attention through the United Nation Millennium Development Goals (MDGs). Increasingly, the role of civil society organizations – most notably Community Based Organisations (CBOs) and Non-Governmental Organisations (NGOs) – in providing Sanitation and solid waste management services to underserved, marginalized, poor or hardly accessible areas and communities is widely celebrated, as fully public and private schemes are thought to be less capable and willing to serve these areas and groups effectively. But little is known about the actual performance of NGOs and CBOs in Urban environmental service provisioning in East African cities. This study explores and compares the extent and success of civil society organizations in providing Urban Sanitation and solid waste services for the poor in the capitals of Kenya, Tanzania and Uganda. Using ideas of modernized mixtures and institutional pluralism we clarify the particular role of civil society institutions among a plurality of Urban environmental service arrangements in East African cities. Major differences are found in CBO/NGO involvement in Sanitation and solid waste provisioning, in the socio-economic characteristics of NGO/CBO service recipients and non-recipients, and in levels of appreciation of these systems.

Civil society participation in Urban Sanitation and solid waste management in Uganda
Local Environment, 2010Co-Authors: J. Tukahirwa, Arthur P.j. Mol, Peter OosterveerAbstract:The inability of local governments to provide basic environmental services in African Urban centres often results in the involvement of other actors in Urban Sanitation and solid waste provisioning, such as non-governmental organisations (NGOs), community-based organisations (CBOs) and private companies. Although NGOs and CBOs are becoming increasingly engaged in Urban service provisioning, little systematic knowledge exists on the kind of activities they take up and the results of these activities. This paper reviews the role of NGOs and CBOs in Sanitation and solid waste management in Kampala, the capital city of Uganda. Against the background of a modernised mixtures perspective and the partnership paradigm, an assessment is made of NGOs and CBOs in provisioning these environmental services. Data were gathered through a survey, face-to-face interviews, and the use of scientific literature, official reports and informal documents. Over 40 NGOs and CBOs were found to be actively involved – often in partn...
