Professor David C Wilson is pleased to co-author an important new publication The Nine Development Bands: A conceptual framework and global theory of waste and development. The open access paper in ISWA’s peer-reviewed journal Waste Management & Research can be downloaded freely. The ‘9 DBs’ builds on the integrated sustainable waste management (ISWM) analytical framework to help characterise waste and resources management (WaRM) systems in cities and countries. Based on over 100 years of combined experience of the authors (Andrew Whiteman, Mike Webster and DCW), the 9DBs is a powerful addition to the waste management practitioner’s toolkit, bringing depth and nuance to understanding of WaRM systems globally.
The early DBs reflect stepwise improvement towards the new
baseline of meeting the SDG 11.6.1 indicators of universal collection and
management in controlled facilities (DB5); while later DBs represent two
prevailing routes to move towards environmentally sound management (ESM) and
the 3Rs (Reduce, Reuse, Recycle). An aspirational DB Zero, a real circular
economy, sits above all 9 DBs, accessible via multiple pathways, posing an
ultimate challenge for development practice. The 9DBs contextualise the
challenge of meeting the waste-related SDGs, in particular for developing
countries striving towards SDG 11.6.1 but also for all countries aspiring to a
circular economy. Whether you are a practitioner, decision-maker, service
provider, or sector activist, the 9DBs will help you to identify the key
pressure points for catalysing change, and focus your time and resources on
achieving maximum impact.

Professor David C Wilson has been working for the last two years with the Rwandan academic Telesphore Kabera to apply the Wasteaware indicators to benchmark performance of the solid waste management (SWM) and recycling system in Kigali, the capital of Rwanda. Their results form the basis of a paper published today in the first ever open access issue of the long established ISWA peer-reviewed journal Waste Management & Research. The paper uses previously unpublished results from the Wasteaware database to compare Kigali’s performance with four other East African capital cities – Dar-es-Salaam, Kampala, Nairobi and Maputo.
The Wasteaware benchmark indicators grew out of work originally carried out for UN-Habitat’s Soild Waste Management in the World’s Cities (2010). They provide a standardised method to characterise the performance of a city’s SWM and recycling system across some 15 indicators, some quantitative and some qualitative, covering both waste generation, the physical aspects of waste and resource management, and various governance aspects. Results for the first 40 cities were used extensively in UNEP and ISWA’s inaugural Global Waste Management Outlook (2015). They are now being applied widely, both to characterise the baseline position in a city; to identify priority areas for improvement; and to monitor progress over time.
From this paper on East Africa, the stand-out result is the relatively high collection coverage achieved in two of the cities: in Maputo with extensive international technical assistance, and in Kigali using its own local resources. In both cases, governance factors are key. Kigali uses a public-private partnership (PPP), with exclusive franchises in 35 sectors being tendered every three years; households pay an affordable fee depending on their ability to pay (the service is free to the poorest category); 95% fee collection rates are achieved, partly through co-collection with charges for local security patrols, which is a service people value highly given the recent history of the country.
Another key priority to improve solid waste management across East Africa is to eliminate open dumping – only Kampala currently has an engineered disposal site. Recycling rates also need to be increased – only Nairobi currently has a good baseline to build on (30%). Common weaknesses include a lack of segregation at source; and of institutional capacity and of available and reliable waste data.
