    Green, open spaces and transport for healthy and sustainable cities in asian developing countries
    (Universiti Putra Malaysia Press, 2021-07-31T00:00:00) Singh, Kiran Kumari; Katewongsa, Piyawat; Wijaya, Nurrohman; Kwan, Soo Chen
    Introduction: This paper presents the case studies of the green, open spaces and transport issues in three cities of the Asian region based on the work of participants from the Workshop of Health in Urban Planning. Methods: Three case studies were collected from the participants of Thailand, India, and Indonesia, and compiled under the theme. Results: The first case study presents findings from the Thailand's Survey on Physical Activity (SPA), and various strategies taken by the Thai government to improve physical activity levels among the Thai population and children, including improved accessibility, walkability; and reconstruction of school curricula. The second case study is an empirical study of the geographical extent and type of green spaces accessible to the urban population, and their usage in the city of Varanasi, India, in the wake of Yoga practice popularity. The third case study discusses the insufficient transport infrastructures, along with the influx of visitors from outside the city as the cause of severe traffic congestions and emissions in Bandung city, Indonesia. The governments' action plans and recommendations for improvements of the city environment are discussed. Conclusion: Integrating health into urban and transport planning needs co-operations from multiple stakeholders including the government, private sectors, and the communities, especially from the early phase of development. � 2021 UPM Press.

    Inactivation of bacterial pathogenic load in compost against vermicompost of organic solid waste aiming to achieve sanitation goals: A review
    (Elsevier Ltd, 2017) Soobhany, N.; Mohee, R.; Garg, V.K.
    Waste management strategies for organic residues, such as composting and vermicomposting, have been implemented in some developed and developing countries to solve the problem of organic solid waste (OSW). Yet, these biological treatment technologies do not always result in good quality compost or vermicompost with regards to sanitation capacity owing to the presence of bacterial pathogenic substances in objectionable concentrations. The presence of pathogens in soil conditioners poses a potential health hazard and their occurrence is of particular significance in composts and/or vermicomposts produced from organic materials. Past and present researches demonstrated a high-degree of agreement that various pathogens survive after the composting of certain OSW but whether similar changes in bacterial pathogenic loads arise during vermitechnology has not been thoroughly elucidated. This review garners information regarding the status of various pathogenic bacteria which survived or diffused after the composting process compared to the status of these pathogens after the vermicomposting of OSW with the aim of achieving sanitation goals. This work is also indispensable for the specification of compost quality guidelines concerning pathogen loads which would be specific to treatment technology. It was hypothesized that vermicomposting process for OSW can be efficacious in sustaining the existence of pathogenic organisms most specifically; human pathogens under safety levels. In summary, earthworms can be regarded as a way of obliterating pathogenic bacteria from OSW in a manner equivalent to earthworm gut transit mechanism which classifies vermicomposting as a promising sanitation technique in comparison to composting processes. ? 2017 Elsevier Ltd
