Both Malaysia and the HKSAR have no homelessness legislation and rely heavily on the voluntary sector. Positive non-policy allows the government to intervene in homelessness, often at times of crisis, without being constrained by legal obligations and by outsourcing services. We discuss its colonial background and current relationship to anti-welfarism and highlight both current punitive and caring policies. We conclude by identifying three main areas for improvement in homelessness policy, while calling for further research into workable solutions within this concept..

Toshio Mizuuchi, Geerhardt Kornatowski, Taku Fukumoto, Diversity of Urban Inclusivity: Perspectives Beyond Gentrification in Advanced City-Regions, Springer, 2023.03, This book explores, situates, and discusses the contours of urban inclusivity amidst and beyond the well-researched neoliberal turn in urban governance. While it is generally accepted that urban social issues are susceptible to global woes, these perceptions draw only limited attention to the plurality of interventions that cities undertake—or facilitate—in managing their social turfs. By addressing the apparent lack of theorizations on everyday heterogeneities in urban place-making, especially in non-Western contexts, this book highlights the role of inclusionary practices by different stakeholders as an explicit pattern of urbanization. It does so by focusing on old urban centralities that have an outspoken history in experimenting with inclusivity. The book is guided by two interrelated questions: (1) What particular urban settings promote inclusionary features in contrast to the conspicuous exclusionary mechanisms of market-led urbanization, and (2) how do we conceptualize these features in dialogue with concurrent urban theories that continue to grapple with the structural properties of exclusionary urbanization under the auspices of the neoliberal turn and gentrification? To answer these questions, the chapters provide a rich empirical account of inclusionary initiatives by the city governments, the voluntary organization sector, and informal communities, each revealing a unique new set of spatial approaches to urban inclusivity. The book concludes with the political implications of envisioning urban inclusivity as a negotiatory moment between key stakeholder interests in a capitalist society. Primarily intended for researchers and graduate students in the fields of urban geography, sociology, migration, and welfare studies, the book is also a valuable source for policymakers and practitioners in the fields of social planning and civil society at large..

1.	Geerhardt Kornatowski, Not Size, but Quality: 'Public Subdivided Flats' as a Pragmatic Solution to Deteriorating Living Space in Hong Kong, Shrinking Domesticities Tokyo Seminar, 2023.07, Hong Kong is perhaps the epitome of shrinking domesticities. This presentation discusses recent social housing initiatives for poor households living in subdivided flats. These flats, often managed through co-living arrangements, are representative of an increasingly unaffordable housing market with low tenancy control on the one hand, and lagging public housing supply on the other. In response, third sector organizations have experimented with underutilized private housing to provide small but livable housing units to underserved populations, primarily in old inner-city neighborhoods. Based on interviews with social housing providers and social workers, I will argue that while the shrinking of space (for the benefit of developers and owners) is rather an accepted fact, it is the systematization of substandard subdivision practices that has become the main target of social intervention by non-governmental interest groups. I will mainly refer to the case study of a homeless organization, in particular how it approaches the aspects of property negotiation, fundraising and qualitative design. Finally, the presentation will consider the practical implications for inclusionary housing for vulnerable populations in the East Asian urban context..
2.	Geerhardt Kornatowski, Nudging Informality through “Nonabstract Pragmatism”: Hong Kong’s Social Housing Movement and the Experiment of “Public Subdivided Flats”, Society for Hong Kong Studies Annual Conference, 2023.06, Hong Kong's current housing policy is in a state of flux. While the 2014 Long-Term Housing Strategy was remarkably hesitant about the 'practicality' and 'quick-fix' approach of third sector-led social housing, the government has recently come up with its own quick-fix solution to the housing shortage, most notably through its Light Public Housing Scheme. Set against this background, this paper will examine the role of what is now loosely framed as the social housing movement and its current strategies for providing decent, transitional housing outside of formal policy. I argue that the movement's experimentation with informal but very pragmatic and concrete means of housing provision has had an important (though not always conspicuous) impact on the housing landscape, particularly in the old urban areas. The movement itself is primarily a response to the failed informality of subdivided flats, especially after the 2011 Fa Yuen Street fire. The initial objective of social housing is to provide an adequate intermediate step between substandard private rented housing and public rented housing. Through interviews with key stakeholders, I examine the actual experiments that took place during the materialisation of this type of housing and the current initiatives that have evolved beyond its primary objective..
