Dissolved uranium, radium and radon evolution in the Continental Intercalaire aquifer, Algeria and Tunisia

Natural, dissolved 238U-series radionuclides (U, 226Ra, 222Rn) and activity ratios (A.R.s: 234U/238U; 228Ra/226Ra) in Continental Intercalaire (CI) groundwaters and limited samples from the overlying Complexe Terminal (CT) aquifers of Algeria and Tunisia are discussed alongside core measurements for U/Th (and K) in the contexts of radiological water quality, geochemical controls in the aquifer, and water residence times. A redox barrier is characterised downgradient in the Algerian CI for which a trend of increasing 234U/238U A.R.s with decreasing U-contents due to recoil-dominated 234U solution under reducing conditions allows residence time modelling ∼500 ka for the highest enhanced A.R. = 3.17. Geochemical modelling therefore identifies waters towards the centre of the Grand Erg Oriental basin as palaeowaters in line with reported 14C and 36Cl ages. A similar 234U/238U trend is evidenced in a few of the Tunisian CI waters. The paleoage status of these waters is affirmed by both noble gas recharge temperatures and simple modelling of dissolved, radiogenic 4He-contents both for sampled Algerian and Tunisian CI and CT waters. For the regions studied these waters therefore should be regarded as “fossil” waters and treated effectively as a non-renewable resource.

Challenges of a Developmental Idea towards Sustainability

This paper attempts to situate and deconstruct the meanings associated with the term development in the context of the developing world. The arguments made highlights the deeply contested and fragmented terrain of development. The paper provides a historical overview of the changing nature of discourses on development, how the imageries of development have shifted since the postwar period. It deploys diverse meanings associated with development as a concept and as a theory. Thus development without dignity means little for those living in the margins of the society. At the same time the language of development has undergone revolutions and convulsions and the role of buzzwords and catch phrases have only helped to prolong misery in a neoliberal world. Development has become a 'one size fits all' concept shorn of cultural and regional specificities. It has been decontextualised and dehumanised to relate to targets
resulting in greater dissonance than resolution of aim and outcomes. The way forward is a better appreciation of the cultural capacity of the social groups for whom development is critical for survival. The conclusion highlights the endemic contradictions inherent in the meaning and delivery of development as a goal, especially when we seek to achieve resilient and sustainable development.

Thinking ‘Dignity’ as a basis towards inclusive development

In an era of increasing political disenfranchisement, deep economic inequalities and associated social humiliations encountered by the rapidly globalising planet, this paper seeks to chart the current thinking about the paths that civil society need to take in order to achieve distinctive peace. Here commitment as part of the universal cosmopolitan order is critical to go beyond the binaries of religious and cultural differences. The role of dignity, of interdependency, respect and understanding has become all the more critical to sustain hope and life in this age of austerity. The paper argues for an empowered citizenship, based on dignity and respect to think socially towards inclusive development.

Lost in Transition? Emerging forms of residential architecture in Kathmandu

Kathmandu has been the last few cities in the world which retained its medieval urban culture up until twentieth century. Various Hindu and Buddhist religious practices shaped the arrangement of houses, roads and urban spaces giving the city a distinctive physical form, character and a unique oriental nativeness. In recent decades, the urban culture of the city has been changing with the forces of urbanisation and globalisation and the demand for new buildings and spaces. New residential design is increasingly dominated by distinctive patterns of Western suburban ideal comprising detached or semi-detached homes and high rise tower blocks. This architectural iconoclasm can be construed as a rather crude response to the indigenous spaces and builtform. The paper attempts to dismantle the current tension between traditional and contemporary 'culture' (and hence society) and housing (or builtform) in Kathmandu by engaging in a discussion that cuts across space, time and meaning of building. The paper concludes that residential architecture in Kathmandu today stands disoriented and lost in the transition.

Unsettling modernity: Shifting values and changing housing styles in the Kathmandu Valley

Abstract

Culture has always been important for the character of the cities, as have the civic and public institutions that sustain a lifestyle and provide an identity. Substantial evidence of the unique historical, urban civilisation remains within the traditional settlements in the Kathmandu Valley in Nepal; manifested in houses, palaces, temples, rest houses, open spaces, festivals, rituals, customs and cultural institutions. Indigenous knowledge and practices prescribed the arrangement of houses, roads and urban spaces giving the city a distinctive physical form, character and a unique oriental nativeness. In technical sense, these societies did not have written rules for guiding development. In recent decades, the urban culture of the city has been changing with the forces of urbanisation and globalisation and the demand for new buildings and spaces. New residential design is increasingly dominated by distinctive patterns of Western suburban ideal comprising detached or semi-detached homes and high rise tower blocks. This architectural iconoclasm can be construed as a rather crude response to the indigenous culture and built form. The paper attempts to dismantle the current tension between traditional and contemporary ‘culture’ (and hence society) and housing (or built form) in the Kathmandu Valley by engaging in a discussion that cuts across space, time and meaning of architecture as we know it.
