This article takes an autobiographical approach in describing the evolution of the equity and environmental justice debate. The intent is not only to provide a historical approach in identifying the emerging research and policy questions, but also to describe the author's own scholarly growth in studying them.

Purpose – The vulnerability and adaptive capacities of cities in Latin America have received relatively less attention compared to other regions of the world. This chapter seeks to address these gaps by (a) examining vulnerability to the health impacts from air pollution and temperature, and exploring whether socioeconomic factors between neighborhoods differentiate these risks within the cities of Bogota, Buenos Aires, Mexico City, and Santiago and (b) assessing the capacity of urban populations to perceive and respond to vulnerability and risk.

Design/methodology/approach – Because of the complex nature of vulnerability, we combined a set of quantitative and quantitative methods and data to determine whether and under what conditions the people in these cities are vulnerable (e.g., Time Series Analysis, Generalized Linear Model, and statistical correlations of exposure and human mortality with socioeconomic vulnerability).

Findings – We found high levels of PM10, ozone, and other criteria air pollutants in three cities for which we had data. However, the pattern of their impacts on health depends on the particulars of pollutant levels and atmospheric and weather conditions of each city. Our results reflect the varied facets of urban vulnerability and shed light on the nature of the associated human health risks. Although wealthy populations have access to education, good quality housing, and health services to mitigate some environmental risks, overall the data show that health impacts from air pollution and temperature in the study cities do not necessarily depend on socioeconomic differentiations.

Research limitations/implications – Although we sought to use quantitative and qualitative methods, given the complexity of the research, it has proven difficult to fully explore these issues across scales and with a full accounting of local context.

Practical implications – Our findings show that wealthy and educated populations may be equally at risk to the health implications of air pollution. Policies designed to mitigate these risks should not use socioeconomic characteristics as predictors of a population's risk in relation to air pollution.

Originality/value – This research contributes valuable insights into the dynamics of vulnerability to air pollution in Latin American cities, a region that has been historically underrepresented in empirical studies of urban risk. We have also combined a range of methods and approaches to improve our understanding of the multifaceted nature of urban vulnerability to global environmental change.

This chapter discusses some issues of diversity in hazard mitigation when just recovery is considered or not. Justice in hazard mitigation becomes crucial considering unequal distribution of resources, systemic racism, and social vulnerability to hazards. While there has been research on just recovery, there is little or no evidence of research that examines the issue of equity and justice in hazard mitigation, This chapter discusses what hazard mitigation is, the Disaster Mitigation Act of 2000 focusing on the planning process, public involvement in the planning process, some planning theories on vulnerability, and building the case for achieving and striving for justice and equity in promoting diversity in hazard mitigation. The chapter makes some recommendation on how to achieve diversity in hazard mitigation.

Risk assessments are the very basis on which planning and implementation are carried out. In the context of urban risk management, the assessment processes are complex to understand as they involve multi-sectoral parameters. Many of the issues involved are of technical nature, but this also requires focus on the principles behind the assessment process including participatory assessment tools.

Action planning is a participatory, short-term, visible, output-oriented process that enables urban community groups to plan the development of risk reduction actions in their locality and to lead the implementation of the action plans.

There are three kinds of actions that emerge from an action planning process: (i) those that can be implemented by the community groups themselves, (ii) those that need some external help for implementation, and (iii) those that can only be implemented by specialized agencies from outside the community. Implementation management processes thus need to look at how internal systems can be established to operationalize self-action, and to coordinate external interventions.

Cities have been exposed to a variety of natural disasters such as flooding, extreme temperatures, storms, earthquakes, and other natural shocks, and have had to respond and adapt to such pressures over time. In the context of global climate change, natural disasters have increased across the globe. Apart from climate change, many urban environments in Latin America are experiencing significant transformations in land use patterns, socio-demographic change, changing labor markets, and economic growth, resulting from recent decades of globalization. Such transformations have resulted in the internal fragmentation of cities. In this context, the purpose of the present chapter is to demonstrate the importance in both theoretical and methodological terms, of integrating the concept of socio-environmental fragmentation into urban vulnerability research in order to make progress toward higher degrees of local sustainability in those areas of the city that suffer natural disasters and fragmentation.

A mixed methods approach is used in order to combine different technical issues from urban and climate change studies.

The findings are related to the importance of an integrated approach, regarding the complexity of urban life, and the relationship between the urban, the social, and the environmental phenomenon.

This chapter relates to the revisit of the current state of preparedness and to determine whether further adaptations are required. The authors understood that these kinds of mixed approaches are necessary in order to understand the new complexity of urban processes.

Fig. 1 illustrates the current level of the integration of three sectors, and Table 1 shows the strategic entry points for the integration.

Pakistan is one of the most climate change and natural disaster-affected countries in the globe, where the lives and livelihoods of people are repeatedly affected due to these natural disasters. Over the past few decades, the country has been impacted by numerous devastating floods, droughts, and storms. As a result, households face enormous complications, particularly those dwelling in disaster-prone areas. Therefore, this study intends to explore the status of household vulnerability and resilience practices of hazard-prone communities in Pakistan from existing literature. This study has identified the 17 most relevant documents. It argues that household vulnerability is increasing consistently with the increasing rate of disaster intensity. Frequent flooding, landslide, erosion, and crop loss are the leading causes of household vulnerability. This study reveals five types of household vulnerability components which look into several livelihood vulnerability indicators of Pakistani households. Moreover, the study unfolds that the main causes of disaster vulnerability are widespread crop loss, a lack of water, loss of soil fertility, and low socioeconomic situations. The major vulnerability components of dwellers are exposure (increasing summer duration, the rapid increase of population house build-up in the riparian areas, and increasing occurrence of hailstorms), sensitivity, low access to education facilities, human loss, diseases infestation, food insecurity, and social conflict), and less adaptive capacity (social networks, migration, poor emergency services, multiple income sources, and less access to the health facility). To address the household vulnerability, this study has also identified four key aspects of resilience, like social resilience, economic resilience, institutional resilience, and physical resilience. The findings will effectively help to understand the dynamics of household vulnerability and resilience and its measurement and management strategy from developed indicators.

The emission of greenhouse gasses, deforestation, and global warming occurred for unplanned developmental designs in most of the South Asian countries. The present study intends to make a comparative study between Bangladesh and the Maldives regarding the impact of pollution on economic growth. The developmental process of these two countries has been interrogated due to the absence of implementing the plan of sustainable development properly. These two countries have been chosen due to having dissimilarities of demographic structure and different developmental models. The density of the population in Bangladesh is the height of the South Asian countries. An unplanned developmental process, urbanisation, and industrialisation made the country highly polluted. Albeit foreign direct investment (FDI) and industrialisation helped Bangladesh to be promoted from a least developed country to a developing country, yet question raises about sustainable development. The South Asian tinny island state, the Islamic Republic of the Maldives has a tourist-based economic structure facing environmental disaster. The erosion of lands and growing air pollution have collectively made the island country jeopardised. This chapter will delineate the effects of pollution on economic growth both in Bangladesh and the Maldives. It will further shed light on application of environmental governance in Bangladesh and the Maldives.
