    Collaborative Framework For Sustainable Flood Risk Managment
    (Center for Human Settlement and Urban Development (CHSUD), 2019-06-01) Adejumo, T. O.
    The unpredictable weather events driven by climate change phenomenon enhanced frequent flooding in previously safe flood plains and littoral settlements. The severity of flood related disaster reached an all-time high in 2012, spreading over 18 states of the federation. The severity prompted the usual Federal Government reactive flood management approach. The piecemeal protective flood management option is not making desired impact. There should be national safety chain to address flood protection, preparedness, response and recovery. This paper advocates for collaborative flood risk management framework to reduce cyclical farmland degradation, infrastructure devastation, property destructions and increasing loss of human life. The paper is underpinned by collaborative inquiry and risk management theories. Collaborative flood risk management demands a clear-cut understanding of probable locations for future flood occurrence and necessary principles and strategic actions to reduce the impact without moving the problem to other geographical locations. On this platform flood risk management is not tackled on political administrative boundaries basis but within natural boundaries of river catchments. It puts demand for synchronization of Federal, State, Local Government and local flood districts flood related activities. Expectations from Federal Government include generation of comprehensive national flood risk management policies with defined national flood risk maps. State Government expectations include provision of specific State flood risk management strategies and flood risk maps. Local Government follow the same pattern. In the absence of City government, State and Local Government collaboration should consider the preparation of local districts flood maps and flood risk management plan. The inputs of all stakeholders including traditional institution, community-based organisations, non-governmental organizations, and prevailing River Basin Authority are important. The choice of flood management at local flood district should be influenced by flood type, flood plain ecological characteristics and available finance.

    Explorative Windows towards Contemporary Nigerian City Form
    (Department of Urban and Regional Planning, University of Lagos, 2014-09-01) Adejumo, T. O.
    At the centre of urban sustainability is city form which addresses the physical characteristics of human settlement including spatial configuration, shape, coverage and developmental density. The reality on ground is that the present chaotic urban sprawl cannot sustain Nigeria as an emerging economy. Historiography as an interpretive research strategy was considered in comprehending dynamic 150 years national urban morphological principles. The paper explored historic antecedence to arrive at developmental windows that should be manipulated in achieving contemporary city form. The paper identified triple waves of developmental principles between 1861 and 2014 responsible for the current Nigerian urban form including the principle of urban centres as ‘produce marketing nodes’, ‘dual urbanism’ and ‘tropical architecture modernism’. Experience from history identified re-introduction of city wedge, vertical urbanism, culture driven public realm and low carbon technology as possible city form explorative windows. The use of natural edge and urban population ceiling influenced by ecological foot print were suggested for new cities. Exploration of pre colonial container features to redefine green belts around the component villages and townships that constituted sprawling metropolitan centres were considered as appropriate city wedge formulae. Planning policies that support intensification through vertical development on defined urban scale model are variants for built up areas. Public realm should be driven by architectural principles with inbuilt capability to narrate meaningful history, cultural affiliation and legible facades especially at the central business district. Since urban sprawl is automobile transportation dependent, the paper also recommended anti-sprawl principle that should emphasize clustering of low carbon public realm activities.

    Geosophic Urbanism: A Localized Urban Developmental Philosophy
    (Society for Peace Studies and Practice (SPSP). Pan African University Press, 2019) Adejumo, T. O.
    Africa’s Priorities for the New Urban Agenda emphasized the promotion of localized systems of sustainable urban development. This is not unconnected with rapid population growth, infrastructural breakdown, disorderliness, unemployment, increased urbanisation rate, large slum concentrations and associated environmental crises. If economic globalization and architectural internationalisation dominated 20th century human settlements, why are African cities the way they are? What thinking process generated the current urban scenario? How planning and design can be done locally within the context of global sustainability paradigm is the truss of this paper. The paper is underpinned by cosmopolitan localism and metanarratives. The paper engages Yoruba pre-colonial worldview urban conceptualization process to demonstrate place based geosophic urbanism. Yoruba urban planning metanarrative rooted in Ifa mythology of earth creation was deciphered to isolate cosmograms, ‘4’ and ‘16’ design numerology, harmonious energy sharing, signs and symbols useful in the redefinition of ordered and vibrant people centred cities. Cladding such place conscious local urbanism with modernisation generates geosophic urbanism. It is nesting contemporary urban features on meaningful local urban templates. On this platform geosophic landscapes is seen as resilient rootstock on which can be grafted compatible symbolic economy and functional modern infrastructures as appealing scions.

    Global Transition and Sustainability Paradigm in Nigerian Architectural Education Curriculum
    (Obafemi Awolowo University Press, 2013-11-01) Adejumo, T. O.
    Man is on planetary transition where the web of human culture including inventions, shelters, governance and cities aligns with nature. This is sustainability on green economy platform. But the naivety with which sustainability as a philosophical force is treated by both architects in academia and practice manifests in inability to comprehend the true meanings of associated terms especially sustainable development, sustainable design; green and organic architecture; ecological design and permaculture. The outcome of such educational void is narrowing sustainability to technical finishes of building construction. At best sustainable architecture is erroneously restricted to design with climate and vernacular intuitive planning. This paper explores the interface of culture and nature to influence sustainability education curriculum on the current green economy transition. Discourse analysis as a methodological clarification underlain the study. The paper argues that sustainable education mind renewal is better achieved at the introductory years of architectural education teaching the students the prime position of man, his shelter in the lager framework of nature. Four broad areas of architectural education that must been influenced are history and theory; technology; studio; and professional Practice. While history/theory should emphasis design theories including biomimicry, biophilia, biomorphism, mimesis, climate change and ‘form follow function’ in its true sense; technology looks inwards bioregionally to modernise construction mechanism. A community oriented studio harmonised the theory and technology to evolve local design agenda in this season of stifling globalisation as a weapon of dominance. The paper recommended that sustainable architecture education in Nigeria should focus on moulding students and producing professionals with high quality of mind set that stress positive environmental ethics; proactive perception of tomorrow; imaginative, creative and constructive thinking on ‘glocalised’ platform; and believe in local community system

    Integrating Heritage Sites into Contemporary Urban Areas: Case Study of Lagos Metropolis, Nigeria
    (Department of Urban and Regional Planning, University of Lagos, 2012-06-01) Lawanson, T. O.; Adejumo, T. O.
    Urban and Regional Planning is primarily concerned with city development, incorporating physical, socio-cultural and economic growth of places. It is expedient for planning to integrate historical factors into the general outlook of a city’s image, identity and overall form. Planners and policy makers are responsible for devising means by which a city’s historical aspects could be harnessed to achieve both political and economic development within the framework of city planning. The Lagos metropolis, Nigeria’s primary urban centre, is growing both in size and population. However, as the city develops, its history, form and ancient characteristics are gradually and continually being expunged. This has led to the development of a Lagos metropolis that has all the properties of an urban center but has failed to realize the potentials which its historical background can contribute to its overall physical, socio-cultural and economic development.This paper assesses the key sites of historical value and importance in the Lagos metropolis, their maintenance and management over the years and the efforts of government and other stakeholders towards their integration into the emerging megacity in line with global best practices, heritage preservation and sustainable urban development

    Valorization of Sand Barrier-Lagoon Ecological Assets in Lagos Smart City Conceptualization
    (University of Lagos Press, 2019-08-01) Adejumo, T. O.
    Urban designers looked through diverse technological windows including engagement of mobile applications to manage urban infrastructures; interactive monitoring; real-time data collection and display; urban mapping and analysis. But the success of a smart city is not solely measured on these technological infusions. Rather a successful smart city place emphasis on achieving high quality of life especially ability to manage the supporting landscapes that carry the ecological processes. This is particularly important in Lagos Sand Barrier-Lagoon bioregion confronted by environmental crises including flooding, storm water pollution and increasing air pollution. Recent climate change impacts, especially flooding, triggered loss of properties, structural failure of infrastructures and increase in sick building syndrome in metropolitan Lagos. This paper disserts how to valorize sand barrier-lagoon natural assets in the quest to conceptualize ecologically resilient Lagos Smart City. The study is underpinned by productive green infrastructure principles and geomorphic urban drainage system. The paper submits that valorization of hydrological system that supports diverse habitats including low land rain forests, freshwater swamps; lowland coastal grasslands; and swamp mangroves forests should underpin livable and environmentally sustainable Lagos smart city. Valorization process consider strategic environmental assessment, urban green infrastructure, pragmatic flood risk management principles and green buildings and energy conservation. The paper recommended four policy statements in line with the four developmental processes.
