Rapid urbanization in the global South is adding epidemiological and nutritional challenges and increasing disease and health burdens for citizens. Greater movement of people, animals, food and trade often provides favourable grounds for the emergence of infectious diseases, including zoonoses. We conduct a rapid evidence scan to explore what is known and hypothesized about the links between urbanization and zoonosis emergence. This points to rapid demographic growth, migration and density, increased movement of people and animals, and changes in land uses as the main processes linked to the prevalence of zoonosis in the urban global South. We argue that this emerging global health challenge is also deeply connected with the urbanization of poverty and inequalities within cities. Tackling the micro-level causal relationships between urbanization and zoonosis requires urgent attention to living conditions, as well as the wider socioenvironmental transitions and structural drivers that produce and reproduce risk accumulation in urban settings.

The limited availability of public transportation in Saudi Arabia leads to an increased demand for private vehicles. An increase in using private cars does not meet the global sustainability goals, e.g., reducing energy consumption and improving the air quality. Road users should be encouraged to use sustainable mobility modes, particularly public transportation, equally accessible to both men and women However, women’s mobility has been somewhat limited and challenged in spatio-temporal terms, and partly due to socio-cultural barriers. This study attempts to understand the gender experience of a sample of public transport users and consider their aspirations and needs into daily mobility. A survey campaign (structured interviews and online questionnaires) was launched in the Dammam Metropolitan Region (DMR), taking four different types of respondents into account. The results suggest a predominant preference for taxis for shopping and leisure activities due to a poor public transport service, pivotally characterized by limited operational routes, hours, and infrastructure. This study ponders upon the adequacy of the supporting infrastructures and interior design of the public buses to women’s needs and compare them with global best practices. The results suggest that, due to the absence of a gender-responsive design and infrastructure, women are forced to use taxis, although privacy and a sense of insecurity often become concerns when traveling alone or with children. The study results allow future research to be expanded, considering women’s mobility patterns, needs, and embedded barriers by comparing the results with current transport policies, plans, and practices.

Being the primate city of Bangladesh, higher population growth and inward migration from rural areas is making Dhaka to experience an unprecedented level of urbanisation. This has brought two-fold implications-pushing it high up the mega-city size ladder while also posing the planners and city managers with more complex spatial and socio-economic challenges to deal with the rapidly expanding urban footprint. Updating the knowledge and evidence-base of Dhaka’s urban growth dynamics becomes increasingly crucial for better functioning of its strategic urban planning and management. Therefore, this research seeks to broaden our knowledge of understanding spatial urban growth patterns and processes of Dhaka over the period of 1988–2005. Hybrid spatial modelling frameworks, incorporating statistical models (in the form of weight-of-evidence approach) along with cellular automata functions, therefore, have been used to comprehend the dynamism of rapid urban growth from 1988 to 2005. As expected, the local version of the transition probabilities (where Dhaka was divided into 18 Spatial Planning Zones), produced improved results compared to the global version (i.e. the whole of the Dhaka metropolitan area). The modelling framework has further been tested as a planner’s ‘what-if’ simulation box to generate near-future scenario using future policy dataset. It appears to have sufficient experimental potential to implement more extensive spatio–temporal land-use modelling process even in sparse data environment such as Dhaka

Food vendors are pivotal in the local food system of most low‐income informal settlements in Nairobi, Kenya, despite being seen as an obstruction and as agents of disease and filth by city authorities. This paper explores the geography of these foodscapes – defined as public sites of food production and consumption – in selected low‐income settlements in Nairobi, focusing on the interaction of food vendors with their surrounding environment and infrastructure services. The research uses participatory geographic information system tools, including food mapping with mobile apps and high‐resolution community aerial views with balloon mapping, to capture and contextualise local knowledge. The community mappers collected data on 660 vendors from 18 villages in Kibera, Mathare, and Mukuru, and situated them on multi‐layered synoptic geographic overviews for each settlement. The resulting data on hazardous areas in relation to food spaces and infrastructure provision allowed local communities to prioritise areas for regular clean‐up activities and assisted advocacy to improve these places in cooperation with local authorities. These multiple visual representations of foodscapes make local food vendors, and the risks they face, visible for the first time. Reframing their “right to safe food and environment” from a social and environmental justice perspective allows local communities to put their experiences, knowledge, and challenges faced at the forefront of urban development planning, policy, and practice.

Pyrolysis1 biochar systems (PBS) could assist in meeting the Scottish Government's target of a 42% reduction in greenhouse gas emissions by 2020 relative to 1990. Drawing on literature review of land use and biomass availability in Scotland at present and in the future, and using established life cycle assessment models, we find that biochar could contribute between 0.4 and 2 MtCO2 equivalent (e) abatement per year in Scotland now (2009), increasing to between 1.4 and 4.2 MtCO2e/yr by 2030 and to between 1.5 and 4.8 MtCO2e/yr by 2050. The practicalities of such biochar deployment are explored further through spatial analysis. Through multi-criteria decision analysis, various factors are weighed up and traded-off against one another to show optimum locations for pyrolysis biochar facilities. The factors considered include proximity to sources (feedstock for biochar production), sinks (for biochar application), and proximity to transport infrastructure etc. Preliminary results show that most of the potentially suitable sites are around the central belt extending into Fife.
