The urban population will rise to 6.7 billion by 2050. The United Nations has committed to provide everyone with safely managed sanitation, but there is limited understanding of the scale of the challenge. This paper describes a methodology for rapid assessment of sanitation in cities including a graphical representation (a shit-flow diagram or SFD) and reports on findings from implementation in 39 cities. The SFD provides high level information for planning purposes covering the entire sanitation system in a city. More than half of the human excreta produced in these cities is not safely managed. The most significant portions of the unsafely managed excreta are: (i) contents of pits and tanks which are not emptied and are overflowing, leaking, or discharging to the surrounding environment (14%); (ii) contents of pits and tanks which are emptied but not delivered to treatment (18%); (iii) fecal sludge and supernatant delivered to treatment but not treated (3%); (iv) wastewater in sewers not delivered to treatment (14%); and (v) wastewater delivered to treatment but not treated (6%). Many cities currently relying on onsite sanitation for safe storage, particularly in Africa, will need new strategies as populations grow. Containment systems that discharge to open drains are common in some Asian cities; these pose a public health risk. Dumping of excreta is widespread and there is a lack of realistic performance data on which estimates of the extent and effectiveness of treatment can be made. The SFD production process can be challenging due to a lack of data and low technical capacity in cities. There is often uncertainty over terminology and over the status of infrastructure. Formalizing definitions for the SFD preparation process was found to be useful in overcoming capacity constraints in cities. The SFD produces a credible snapshot of the sanitation situation in a city. The paper provides evidence of the urgent need for improved management and monitoring of urban sanitation in cities around the world and highlights the role of the SFD as a planning tool.

Using a two-round Delphi study, 15 faecal sludge emptiers from 11 cities in Sub-Saharan Africa have expressed views on the regulation of faecal sludge emptying services. Their responses identify the regulatory mechanisms in place where they operate, their opinions of these mechanisms, and prioritisation of those considered most useful to enable safe emptying services for all urban residents. All respondents (100%) support regulation, with 80% finding the regulation they encounter useful. However, all also state that regulatory mechanisms should extend beyond only rules and sanctions, to incorporate support, incentives and pro-poor mechanisms. This study is the first to provide a first-hand account of Sub-Saharan African private emptiers' willingness to accept clear regulation. In that regard, regulation should be flexible and adapted to the context in order to facilitate fair competition, safe and satisfactory service for customers and workers alike, and to alleviate the public and environmental health risks.

PurposeThe construction industry is one of the largest employment providers in the developing world. It is also one of the least safe industries, with a high frequency of accidents resulting in financial losses, injuries, disabilities and deaths. Decent working conditions and resulting improved worker satisfaction are key to sustainable productivity in the industry. International standards safeguarding construction workers are abundant and ratified by most low‐income countries. This paper aims to examine if these standards are adequately reflected in contracts for construction works; and if they not, how contract clauses can be improved and put into operation.Design/methodology/approachBased on research undertaken in Ghana, India and Zambia from 2000 to 2003, this paper explores the aforementioned points. The paper comprises analysis of contract clauses from the International Federation of Consulting Engineers (FIDIC) and developing country contracts, along with case study findings.FindingsThis paper finds that more legislation is not the urgent issue; incorporating existing legislation into construction contracts and making clauses operational is a priority. This paper identifies practical and cost‐effective procedures for bringing stakeholders together to implement and monitor labour standards, with the aim of contributing to the overall goal of providing “decent work” for all workers in the construction industry.Originality/valueThis paper explores issues around implementing labour standards in construction of minor infrastructure works in low income countries and concludes with suggestions on how best to put contract clauses into operation through a process approach.

Rapid urbanization in developing countries demands better integration of planning and delivery of basic services if cities are to be sustainable, healthy and safe. Sanitation improvements are commonly overlooked as investments go towards more visible services such as water supplies and drainage networks. The Sustainable Development Goal for sanitation and hygiene currently remains severely off-track. This paper presents the findings of a Delphi method survey to identify expert consensus on both why and how to integrate sanitation, by which we mean both sewered and non-sewered sanitation services, into other basic urban services (including water supply, drainage, energy and roads) to achieve better sanitation and broader development outcomes, notably for poor citizens. Consensus on why integration is important highlights the physical interdependence of services, where neglect of one service can compromise gains from another investment or service. Consensus on how includes actions to address political priorities and leadership; governance and capacity constraints; clearer planning, procurement and financing mechanisms; and adopting incremental approaches matched to wider urban strategies. It was suggested that achieving these actions would improve accountability, monitoring and service level audits. Experience from previous integrated urban programmes should be incorporated into formulating new sanitation service agreements across all service types. Supported by better-informed dialogue and decision-making between those responsible for urban sanitation and for associated basic services, we suggest integrated and incremental approaches will enable more sustainable urban services planning to achieve ‘quality of life’ outcomes for poor urban residents.
