Development and the Household: Missing the point?

Over the past two decades development has been shifting its focus toward smaller scales and particular problems. As a result, the household has become an increasingly important institution for development, and has come under increased scrunity as development practitioners and scholars seek to better understand this institution’s functions and foundations, trying to ‘get the household right’. These efforts, rather than clarifying the character and the function of the household, have contributed to its indeterminacy by reifying the very institution they seek to analyse. Arguing that these efforts fundamentally miss the point of examining the household, this paper introduces a different framework of analysis that addresses the household not as a fixed object of research, but as a local construction that embodies flows of power and knowledge both within and transcending the local. Using the example of varying constructions of the household in two villages in Ghana’s Central Region, this article illustrates how such an approach allows us to address the various functions of the household as particular embodiments of these flows, an approach that better explains the endurance or ephemerality of these functions. Such an approach provides a stronger foundation for the consideration of how particular constructions of this institution may have troubling implications for issues like gender equity and sustainability.     

Introductory review of specific factors influencing urban groundwater, an emerging branch of hydrogeology, with reference to Barcelona, Spain

A number of specific factors must be considered when dealing with groundwater in urban areas. Urbanization significantly affects the natural water cycle, both in terms of quantity and quality. In particular, the main contributors to recharge and discharge clearly differ from those in natural systems. Moreover, water can affect underground structures and infrastructure characteristics of cities such as basements, public transport services (trains, underground railways, etc.), and utility conduits. As a result, urban groundwater is emerging as a distinct branch of hydrogeology. The objective of this paper is to review some of the topics that are specific to urban groundwater. These include (1) fluctuations in groundwater levels caused by changes in land and water uses; (2) pollution problems caused by point or non-point sources in urban areas; (3) characterization and quantification of the components contributing to groundwater recharge and discharge; (4) specific characteristics of groundwater flow and solute transport models in urban areas; and (5) integration of data for sustainable urban water management. Some of these issues are illustrated for the particular case of Barcelona, where a comprehensive hydrogeological study has been carried out during the last few years by both the public and the private sectors.

Resumen Se debe considerar una serie de factores específicos al tratar las aguas subterráneas en áreas urbanas. El proceso de urbanización afecta el ciclo natural del agua de manera significativa tanto en lo que se refiere a cantidad como a calidad. En particular, los contribuyentes principales a la recarga y descarga claramente difieren de aquellos aplicables a los sistemas naturales. Es más, el agua puede afectar los estructuras subterráneas de las ciudades tales como sótanos, servicios de transporte público (trenes, trenes subterráneos) y los servicios básicos. Como resultado de esto, la hidrogeologia urbana está emergiendo como una rama específica de la hidrogeología. El objectivo de este artículo es revisar algunos de los temas que son específicos al agua subterránea urbana. Estos incluyen: 1) Fluctuaciones en los niveles de agua subterránea causados por cambios en los usos de terreno y del agua; 2) Problemas de contaminación causados por fuentes puntuales o no puntuales en áreas urbanas; 3) Caracterización y cuantificación de los componentes que contribuyen a la recarga y descarga de agua subterránea; 4) Características especificas de flujo de agua subterránea y modelos de transporte de solutos en áreas urbanas; y 5) Integración de datos para el manejo sostenible de agua urbana. Algunos de estos puntos se han ilustrados para el caso particular de Barcelona en donde se ha llevado a cabo un estudio hidrogeológico amplio durante los últimos años tanto por el sector privado como el público.

Résumé Une série de facteurs spécifiques doit être considérée lorsque leau souterraine en région urbaine est étudiée. Lurbanisation affecte significativement le cycle naturel de leau, autant du point de vue quantitatif que qualitatif. Plus particulièrement, les zones de recharge et de décharge diffèrent considérablement des systèmes naturels. Leau souterraine peut affecter les structures souterraines ainsi que les infrastructures municipales telles que les sous-sols, les systèmes de transport publique (trains, métros, ...) et les conduits de service. De ce fait, lhydrogéologie en milieu urbain émerge comme une branche distincte de lhydrogéologie classique. Lobjectif de cet article est de revoir certaines notions qui sont spécifiques à létude de leau souterraine en milieu urbain. Parmi ces notions : 1) les fluctuations de la nappe phréatique causées par des changements dans lutilisation du territoire et de leau, 2) les problèmes de pollution causés par des sources ponctuelles ou diffuses en milieu urbain, 3) la caractérisation et quantification des composants qui contribuent à la recharge et décharge des aquifères, 4) les caractéristiques spécifiques des modèles découlement de leau souterraine et de transport de solutés en milieux urbain, et 5) lintégration des données pour la gestion durable de leau en milieu urbain. Certaines de ces questions sont étudiées pour le cas particulier de la ville de Barcelone où une étude hydrogéologique complète a été menée au cours des dernières années par les secteurs privé et public.

     

A Model to Calculate what a Remote Sensor ‘Sees’ of an Urban Surface

Whilst the measurement of radiation emissions from a surface is relatively straightforward, correct interpretation and proper utilization of the information requires that the surface area seen be known accurately. This becomes non-trivial when the target is an urban surface, due to its complex three-dimensional form and the different thermal, radiative and moisture properties of its myriad surface facets. The geometric structure creates shade patterns in combination with the solar beam and obscures portions of the surface from the sensor, depending on where it is pointing and its field-of-view (FOV). A model to calculate these surface-sensor-sun relations (SUM) is described. SUM is tested against field and scale model observations, and theoretical calculations, and found to perform well. It can predict the surface area seen by a sensor of known FOV pointing in any direction when placed at any point in space above a specified urban surface structure. Moreover, SUM can predict the view factors of the roof, wall and ground facets seen and whether they are sunlit or shaded at any location and time of day. SUM can be used to determine the optimal placement and orientation of remote sensors to study urban radiation emissions; if the facet temperatures are known or modelled it can calculate the average temperature of the system, and it can determine the directional variation of temperature (anisotropy) due to any particular surface-sensor-sun geometric combination. The present surface geometry used in SUM is relatively simple, but there is scope to make it increasingly realistic.     

Groundwater quality and its change over a decade: An analysis of a coastal urban environment from the west coast of India

Mangalore, one of the fastest growing cities along the west coast of India has witnessed a leap in industrialisation and urbanisation during the last decade. This study focuses on the quality of the groundwater of Mangalore city. The results are compared with an earlier study to record the change in water quality over a decade. HCO₃ and Na were found exceeding the highest desirable limit of the World Health Organisation (WHO) and Indian Standards Institute (ISI) standards for drinking water. The pH values at seven localities are not within the limits prescribed by WHO or ISI (highest desirable level or maximum permissible level). The present study shows that there has been an enrichment of chemical constituents during the last decade and that the Gurupur River, which flows parallel to the coast, plays an important role in impeding saltwater intrusion along the coast.

Accessibility for High Asia： Comparative Perspectives on Northern Pakistan＇s Traffic Infrastructure and Linkages with Its Neighbours in the Hindukush-Karakoram- Himalaya

Starting with a discussion of development concepts which were applied in practice and which followed the developmentalist paradigm the expansion of traffic infrastructure in colonial and post-colonial periods is presented for the High Asian mountain rim. Selective railways and roads are the major feature of this development, which aimed first on serving the convenience of hill station visitors and followed strategic considerations later on. This bias between regional planning and implementation remains a characteristic feature. At the same time traffic infrastructure without asphalt roads is important for the mountain areas, thus breaking up the strong correlation between development and asphalt roads.
