Community-based approaches for addressing the urban sanitation challenge

Urban sanitation presents one of the most significant service delivery challenges related to poverty alleviation and sustainable development in the developing world. The past decade has witnessed innovations in service delivery approaches for unserved rural and urban settlements with a clear policy shift to community-based approaches that attempt to overcome the supply-led, over-engineered sanitation solutions of the past decades. This article presents two examples of new developments: the urban-focussed household-centred environmental sanitation (HCES) and the rural-focussed community-led total sanitation (CLTS) approaches. The internationally renowned CLTS approach has achieved considerable success since its introduction, by harnessing community and small private sector capacity to solve sanitation problems locally. Experience with validation of the HCES approach in a variety of urban sites in Africa, Asia and Latin America is presented in the second part of the article highlighting some of the lessons learned. The article closes by arguing that a combination of HCES and CLTS, two field-tested methodologies, has the potential to improve the sustainability of sanitation service interventions.

Pathways for Sustainable Sanitation: Achieving the Millennium Development Goals

The report is a product arising from the work of the Sustainable Sanitation Alliance which was initiated prior to the International Year of Sanitation in 2008 in an attempt to inject sustainable development ideas into the sanitation sector. It functions as a vision document for those policymakers, researchers and practitioners that are striving towards fundamental reform and improvements within the sanitation sector in both rural and urban populations in all countries of the world. It reviews the global progress being made towards achieving the Millennium Development Goal (MDG) target on sanitation. A literature review is presented on sanitation provision including human health impacts and the estimated costs and benefits of achieving the MDG target. The report also provides a critique in that the UN has not yet introduced the concept of sustainability into the MDG programme in general and in particular into the sanitation sector which is highly dysfunctional and suffering from limited political leadership at both the local and global levels. It introduces the various sustainable sanitation options available and what approaches can be taken to improve sanitation systems – not just toilets which are only a small part of the overall system of food, nutrients and water cycles. The study estimates the numbers of urban and rural households, including slum populations that are being targeted in all world regions. It also evaluates the historic trends in morbidity and mortality linked to diarrhoea arising from lack of functioning sanitation services comparing these to the UN data on sanitation coverage. The report estimates the potential fertiliser replacement capacity that reuse of human excreta can have for all world regions. Finally it provides a vision for future development within the sector where more sustainable options like source separation and reuse are promoted giving positive environmental or “green” impacts but also catalysing greater involvement and understanding on the part of individuals in society.

Perceptions of local sustainability in planning sanitation projects in West Africa

The purpose of this study was to examine local perceptions of sustainability in the context of sanitation interventions in Burkina Faso and Mali, West Africa. Through a series of interviews with local actors criteria for sustainable sanitation were defined in the local context. These local criteria were compared with criteria found in international literature and planning practices used in two sanitation projects. The results from the interviews emphasize criteria related to behaviour change processes, while criteria in literature are either oriented toward technical assessments or project guidelines. The case studies show an attempt to merge academic and pragmatic perspectives by addressing both the technical requirements and processes of social change. As we seek to improve results within the sector it is important to start reflecting on what criteria and sustainability definitions are used in specific approaches.
