The second round of the Local Transport Plan (LTP2) process in England presents unique challenges and opportunities for integrating Local Air Quality Management (LAQM) within current transport planning policy. Using content analysis of LTP2 documents from nine English authorities, and results from a questionnaire survey of local government officers undertaken in late 2007, this paper charts the changes in the integration of air quality management within the transport planning process since 1997. While substantial improvements in policy integration were observed within the selected case studies, the paper demonstrates that such improvements are often constrained by institutional complexities that create implementation gaps between national objectives and local decision-making outcomes.Local Air Quality Management (LAQM), Local Transport Plan (LTP), Air Quality Objectives (AQO), policy integration, institutional complexities and inter-professional engagement,
This paper provides an overview of the emergent public health risks attributable to air pollution in Lagos and solutions to reduce them. Growing evidence has substantiated a causal relationship between air pollution and mortality, hospital admissions for respiratory or cardiovascular disease and an associated increased risk of myocardial infarction. Lagos, the former capital of Nigeria with a population of 15 million has been identified as one of the fastest growing megacities with annual mean concentrations many times higher than the thresholds recommended by the WHO. Given the urban conglomeration of Lagos, this paper shows that differential traffic density, socio-economic conditions, access to healthcare and proximity to sources of emissions create differential susceptibility of communities to ill health attributable to air pollution, especially within vulnerable groups including children, the elderly and pregnant women. The paper therefore argues that an understanding of the scale and spatial variation of air pollution is not sufficient for reducing the risks posed to public health. An effects-based approach needs to be adopted in order to frame air pollution problems in the city within a public health context, rather than as an environmental nuisance.
Since 1988 the Nigerian Government has introduced environmental legislation aimed at reducing the atmospheric impact of various sources of pollution. Emphasis has often been placed on mitigating pollution from the oil and gas industry. However, various studies indicate significant ambient air pollution from other sources due to vehicular traffic growth in urban areas, increased reliance on petrol and diesel fuelled generators for electricity supply in homes and other public facilities, uncontrolled open incineration of waste and major thermal power stations within the city limits. In this paper, we make the case for the establishment of risk-based air quality management approach based on monitoring, modelling and assessment of these other sources. We outline four important elements that should be considered in order to achieve this recommended approach. These elements are conceptualised within the existing institutional, organisational structures and capacity in Nigeria.
Since 1997, Local Air Quality Management (LAQM) has been used as a process through which local authorities in England identify and manage specific air quality problems within their jurisdictions in order to achieve the air quality objectives (AQO). However, the limitation of this process is that of policy disconnect between diagnosis and solutions proffered within it. Over 90% of air quality 'hot-spots' identified through the LAQM are due to traffic-related sources. Hence, the air quality action plans prepared by the environmental health officers (EHO) are improperly calibrated as a policy instrument for tackling most of the problems discovered through the LAQM. The inclusion of air quality as one of the four shared priorities in the second round of the Local Transport Plan (LTP2) therefore implies that the EHO need to engage with the transport planners (TP) at the local level in order to address most of these problems i.e. traffic-related air pollution.Since LAQM and LTP operate as two parallel frameworks with a separate agenda and timetable, adequate connectivity between both policy packages is thereby dependent on the type and level of inter-professional engagement between the departments and officials responsible for both policies at every level of government involved. This paper presents emerging issues from the questionnaire survey of EHO and TP in over 200 local authorities in 2007 as part of a three-year investigation into the effectiveness of achieving the AQO through the LTP in English local authorities. While there is wide support for the achievement of AQO through the LTP, the two groups identified differences in time-scale for delivering both policies, prioritisation of air quality within LTP, and unequal expectations as major factors affecting the integration. These factors indicate the existence of institutional complexities between parallel policy communities in ensuring integration.
