Abstract

Purpose

Flooding is an emerging problem in Ho Chi Minh City (HCMC), Vietnam, and is fast becoming a major barrier to its ongoing development. While flooding is presently of nuisance value, there is a growing concern that a combination of rapid urban expansion and climate changes will significantly exacerbate the problem. There has been a trend of population being rapidly accommodated in new urban areas, which are considered highly vulnerable to floods, while the development strategy by the local government still attracts more property investments into the three new districts on the right side of Saigon River. This paper aims to discuss the increase in the number of residences vulnerable to flooding, to underline the need for more appropriate future spatial development. For the vision, an application of compact and resilient theories to strategic planning and management of this city is proposed to reduce vulnerability. This paper also highlights the need to better understand growing vulnerability to floods related to urban expansion over low-lying former wetlands and the more important role of planning spatial development accompanied with transportation investment which can contribute to flooding resilience.

Design/methodology/approach

This research uses combined-methods geographical information system (GIS) analysis based on secondary data of flood records, population distributions, property development (with the details of 270 housing projects compiled as part of this research) and flooding simulation. This allows an integrated approach to the theories of urban resilience and compactness to discuss the implication of spatial planning and management in relevance to flooding vulnerability.

Findings

The flooding situation in HCMC is an evidence of inappropriate urban expansion leading to increase in flooding vulnerability. Although climate change impacts are obvious, the rapid population growth and associated accommodation development are believed to be the key cause which has not been solved. It was found that the three new emerging districts (District 2, 9 and ThuDuc) are highly vulnerable to floods, but the local government still implements the plan for attracted investments in housing without an integrated flooding management. This is also in line with the development pattern of many coastal cities in Southeast Asia, as economic development can be seen as a driving factor.

Research limitations/implications

The data of property development are diversified from different sources which have been compiled by this research from the basic map of housing investments from a governmental body, the Department of Construction. The number of projects was limited to 270 per over 500 projects, but this still sufficiently supports the evidence of increasing accommodation in new development districts.

Practical implications

HCMC needs neater strategies for planning and management of spatial development to minimize the areas vulnerable to floods: creating more compact spaces in the central areas (Zone 1) protected by the current flooding management system, and offering more resilient spaces for new development areas (Zone 2), by improving the resilience of transportation system. Nevertheless, a similar combination of compact spaces and resilient spaces in emerging districts could also be incorporated into the existing developments, and sustainable drainage systems or underground water storage in buildings could also be included in the design to compensate for the former wetlands lost.

Social implications

This paper highlights the need to better understand growing vulnerability to floods related to urban expansion over low-lying former wetlands and emphasizes the more important role of planning spatial development accompanied with transportation investment which can contribute to flooding resilience. Coastal cities in southeast countries need to utilize the former-land, whereas feasibility of new land for urban expansion needs to be thoroughly considered under risk of natural disasters.

Originality/value

A combination of compact spaces with improved urban resilience is an alternative approach to decrease the flooding risk beyond that of traditional resistant systems and underlines the increasingly important role of urban planning and management to combat the future impacts of floods.

Abstract

Due to the more pressing need, the majority of material in this book has dealt with mitigation; interventions to reduce emissions of greenhouse gases (IPCC, 2001) away from a scenario of ‘business as usual’. An early academic review on climate change mitigation and transport appeared in 2007 (Chapman, 2007), a year before the United Kingdom committed itself to the highly ambitious Climate Change Act 2008. The final act sought an ambitious 80% cut in greenhouse gas emissions by 2050. Although criticised in this book as being unrealistic, this is the level of intervention required if ‘dangerous’ climate change is to be avoided (defined as greater than 2°C rise in global temperatures). As Chapter 8 (a policy perspective) explains, such targets, however unrealistic, are informed by considerable input from expert opinion (e.g. Delphi studies) and require a detailed knowledge of current emissions as well as accurate predictions/scenarios of future emissions. For this reason, scenarios and the control of uncertainty were discussed in Chapter 2 towards the start of this book. Indeed, the commonly quoted ‘business as usual’ scenario is in itself too simplistic and highly improbable, not only due to mitigation measures imposed by governments, but also because of the future scarcity of oil which will force change in the medium term regardless. Backcasting is the key tool used to model the continuum of socio-economic scenarios which exist between ‘business as usual’ and the equally unlikely case of all targets being met. However, the science is inherently difficult and the end result is a wide range of permutations and storylines, largely dependent on mitigation. Early progress towards the 80% target has not been promising, but the decarbonisation of the transport sector is still seen as key in meeting the demands of the Climate Change Act 2008. There is a need to tackle the three primary culprits of greenhouse gas emissions in the transport sector: aviation, freight and car ownership (Chapman, 2007). This book has examined in detail how this could be achieved in all these sectors using a range of aspects relating to technological and behavioural change.

Abstract

Climate change is recognised as one of the greatest challenges that contemporary global society faces. The IPCC (Intergovernmental Panel on Climate Change) Fourth Assessment Report (2007) states that it is ‘very likely’ that anthropogenic global warming will result in a temperature rise of between 1.8°C and 4°C by the end of the 21st century. Temperatures at the upper end of this range are considered ‘dangerous’, and the international community is focused on attempting to limit the increase to within 2°C (Meinshausen et al., 2009). Increasing global temperatures are just one consequence. The world will face an increasing level of unpredictable and extreme weather patterns, each with different, but in many cases, serious consequences for life on earth (IPCC, 2007).

Abstract

Purpose – To investigate the potential impacts of future climate change in the United Kingdom on its road and rail networks.

Methodology/approach – The climate change impacts of increasing summer temperatures, decreasing winter temperatures, increased heavy precipitation, greater numbers of extreme weather events and rises in sea level are reviewed.

Findings – Surface transportation is the most exposed element to the localised impacts of climate change. High summer temperatures will result in road rutting, rail buckling and decreased thermal comfort, whereas more intense winter precipitation will cause flooding, landslips and bridge scour across all modes. For all impacts, it is the extreme events (e.g. heat waves and storms) that are potentially the most devastating. As shown, there are some positive climate change impacts. For example, in the case of winter maintenance, all transport networks stand to benefit.

Originality/value – In order for transport to react appropriately to the potential changes in climate, it is essential to understand how the road and rail networks may be affected and to build strategies for both adaptation and mitigation into plans for future developments for both modes.

Abstract

Purpose

The purpose of this paper is to systematically and comprehensively review the extant literature on racial disparities in police use of force.

Design/methodology/approach

The current study uses a narrative meta-review of racial disparities in police use of force through a systematic and exhaustive search of several academic databases (e.g. Criminal Justice Abstracts; EBSCO Host, PsychInfo, etc.).

Findings

The current meta-review identified 41 studies that matched the selection criteria. These studies examined public and police officer perceptions of use of force, rates of use of force, types of force used, neighborhood contextual correlates of use of force, and severity of force used. The relationship between race and use of force remains unclear after an examination of these studies. This indicates a need for high-quality research focusing on comparable operationalization of variables and stronger methodologies.

Research limitations/implications

The research implications derived from this meta-review indicate a need for increased research to better understand the intersections of race and police use of force (and the factors that increase the likelihood of force being used more broadly).

Practical implications

The practical implications derived from this meta-review indicate the need for monitoring techniques, such as the use of police body-worn cameras that could serve to deter inappropriate use of force.

Originality/value

The state-of-the-art review on racial disparities in police use of force is the first of its kind. This study comprehensively reviews the literature on racial disparities in police use of force. This study will be useful for those who wish to further explore racial disparities and use of force issues in policing, and for police managers and administrators who want to address concerns related to racial disparities in use of force in their organization.

Abstract

Purpose – The UK road freight sector is an example of an economically important sector that can be viewed from two different perspectives with regards to climate change: firstly, as a significant contributor to the problem in terms of greenhouse gas emissions, and secondly as a likely recipient of significant impacts (both positive and negative) of any resulting change in climate, especially any increase in extreme weather. It is this relatively neglected second perspective, freight as a vulnerable sector, which is explored.

Methodology/approach – The way in which the freight sector develops in the future will be explored both in terms of the future type of freight operations and potential changes in vehicle technology.

Findings – There is a need to understand how the overlying socio-economic scenario influences the development of the freight sector.

Originality/value – The examination of the impact of climate change on the freight sector is a particularly original aspect of this chapter.
