Effects of thermal insulation on thermal comfort in low-income tropical housing

This paper evaluates the effects of thermal insulation on thermal comfort in low-income tropical housing in Uganda. Dynamic thermal simulations are conducted to assess the effects of wall, roof and floor insulation strategies. 96 combination scenarios are simulated for various geometries, insulation and construction methods. Adaptive approach is used to evaluate the conditions within the case study buildings. The results indicate that external wall insulation improves thermal comfort in all conditions whereas internal wall and floor insulation may deteriorate the conditions. Roof insulation is the most effective strategy to reduce the risk of overheating. Due to the effectiveness of roof insulation and marginal improvements of external wall insulation, especially for brick walls, wall insulation may be disregarded when used in conjunction with roof insulation

Emerging Disease Burdens and the Poor in Cities of the Developing World

Patterns of future urban growth, combined with advances in the treatment of traditional scourges of communicable diseases, will cause a shift in the burden of disease toward category 2 (noncommunicable) and 3 (injury) conditions over the next 30 years. Communicable diseases, particularly HIV/AIDs, will continue to be the most important killers among the poor. However, new risks will emerge for several reasons. First, the marked sprawl of cities in the developing world will make access to care more difficult. Second, increasing motor vehicles and the likelihood of inadequate infrastructure will make air pollution and accidents in road traffic more common than in the past. Third, impoverished urban populations have already shown a propensity toward undernourishment, and its obverse, obesity, is already emerging as a major risk. Also, the large projected increase in slums suggests that violence and homicide will become a more important burden of health, and very large hazards will be created by fire-prone, insubstantial dwellings that will house nearly two billion people by 2030. In addition, decentralized governance will exacerbate the tensions and discontinuities that have plagued the management of health issues on the urban fringe over the past decade. Accordingly, public health agencies will need to adjust to the regional and country-specific factors to address the changing profile of risk. This analysis suggests that four factors – levels of poverty, speed of city growth, sprawl in cities, and degree of decentralization – will have importance in shaping health strategies. These factors vary in pace and intensity by region, suggesting that health care strategies for Category II and III conditions will need to be differentiated by region of the world. Also, interventions will have to rely increasingly on actors outside the ranks of public health specialists

Tackling Women's Vulnerabilities through Integrating a Gender Perspective into Disaster Risk Reduction in the Built Environment

The majority of human and direct economic losses from natural hazards occur as a result of damage to the built environment due to the vital role that the built environment performs in serving human endeavours. One of the key reasons for people in developing countries to be more vulnerable to natural disasters than their wealthier counterparts is the limited capacities in their construction industries. Among the people in developing countries, women are evidently even more vulnerable to natural disasters. Due to higher disaster vulnerability of women, recognising the different roles, capacities, vulnerabilities and needs of women, and considering them in disaster risk reduction in the built environment is significant to reduce women’s disaster vulnerabilities. Gender mainstreaming as a way of bringing a gender perspective into disaster risk reduction can be applied to recognise the varying needs and capacities of women, and integrate them into disaster risk reduction in the built environment. The paper in this context aims to demonstrate how gender mainstreaming helps to bring a women’s perspective into disaster risk reduction in the built environment. It identifies two main steps which involve in the process, identification of women’s DRR knowledge and needs, and integration of the identified DRR knowledge and needs into DRR in the built environment. The paper provides an account of the process that the study established to incorporate a gender perspective into disaster risk reduction in the built environment based on a case study conducted in Sri Lanka. It further discusses how the social, economic, political and environmental context influences the process of gender mainstreaming in disaster risk reduction in the built environmen

Redefining Water Security through Social Reproduction: Lessons Learned from Rajasthan's ‘Ocean of Sand’

One of the most urgent challenges facing the world today is ensuring local water security under rapid climate variability and change. This is of particular importance in a country like India, where over half of the people are involved in farming, and agricultural losses due to climate change are estimated to be as high as 30 per cent by 2080. This ethnography in the arid village of Bhiwadi, West Rajasthan empirically links the reintroduction of local water harvesting technologies with the building of sustainable social reproduction in subsistent communities. By emphasising both the role of gender and the informal economy – and institutions – this ethnography provides a more thorough picture of the individuals and collective actors involved in localised and resilient technologies within global economic and climatic processes

Following the footsteps: Urbanisation of Wa Municipality and its synergism in risk accumulation, uncertainties and complexities in urban Ghana.

Global demographic characteristics have witnessed a significant shift with more than half of the world's population crossing the rural-urban threshold in 2008. In Ghana, the 2010 census report revealed 50.9% urban population. While the many benefits of organised and efficient cities are well understood, it must be recognised that rapid, often unplanned urbanisation brings risk of profound social instability, risk to critical infrastructure, potential water crises and the potential for devastating spread of disease. These risks can only be further exacerbated as this unprecedented transition from rural to urban areas continues. This also means stakes are high for public and private interventions to ensure that urbanisation reinforces rather than retards prosperity. In spite of these past experiences, urban governance policies in emerging smaller cities are frequently ambivalent and piecemeal, exhibiting similar negative tendencies, a development that has received less academic attention. This study adopted multiple research techniques and the data were generated through a structured questionnaire survey, personal interviews and discussions. Based on our conviction that the development trajectory of any city hinges on the quality of its physical foundation, we seek to fill the knowledge gap using the Wa Municipality, the least urbanised but one of the fastest urbanising cities in Ghana today, as a case study. The results reveal emerging tendencies that indicate that Wa appears to be following in the footsteps of its predecessors - experiencing an inefficient potable water supply system and chronic sanitation situation, making diarrhoea one of many challenges for residents. It is ultimately suggested that a collaborative partnership with all key stakeholders is a better option to reap the potential for urbanisation to strengthen economic growth and development

Access and utilisation of primary health care services comparing urban and rural areas of Riyadh Providence, Kingdom of Saudi Arabia

The Kingdom of Saudi Arabia (KSA) has seen an increase in chronic diseases. International evidence suggests that early intervention is the best approach to reduce the burden of chronic disease. However, the limited research available suggests that health care access remains unequal, with rural populations having the poorest access to and utilisation of primary health care centres and, consequently, the poorest health outcomes. This study aimed to examine the factors influencing the access to and utilisation of primary health care centres in urban and rural areas of Riyadh province of the KSA

Urban Governance for Adaptation: Assessing Climate Change Resilience in Ten Asian Cities

Rapidly expanding urban settlements in the developing world face severe climatic risks in light of climate change. Urban populations will increasingly be forced to cope with increased incidents of flooding, air and water pollution, heat stress and vector‐borne diseases. This research, undertaken with a set of partner research institutes, examines how to manage climate‐related impacts in an urban context by promoting planned and autonomous adaptation in order to by improve resilience in a changing climate. It investigates the linkages between the characteristics of pro‐poor good urban governance, climate adaptation and resilience, and poverty and sustainable development concerns. The paper develops an analytical framework by combining governance literature with rapid climate resilience assessments conducted in ten Asian cities. Based on this empirical data, we argue that a number of key characteristics can be identified to assess and build urban resilience to climate change in a way that reduces the vulnerability of the citizens most at risk from climate shocks and stresses. These characteristics form the basis of a climate resilient urban governance assessment framework, and include (1) decentralisation and autonomy, (2) accountability and transparency, (3) responsiveness and flexibility, (4) participation and inclusion and (5) experience and support. This framework can help to assist in the planning, design and implementation of urban climate change resilience‐building programmes in the future
