It is central to the sustainable development debate. The aim of this research is to examine the effects of urban landuse and its impact on selected public utility services in Akure with a view to improve strategies to protect these utilities for sustainable development. The research was conducted using remote sensing, Geographical information System and questionnaire to collect the required data for the purpose of fulfilling the objectives of this study. In this study of analyzing the urban landuse change, 2010 and 2018 IKONOS are used in a post classification comparison analysis to map the landuse changes and identify the conversion process in Akure. The landuse change statistics results obtained revealed that residential landuse has changed rapidly for the periods (2010-2018). The results also show increase in commercial landuses between the same periods. The results of the analysis reveal that the built-up area has been growing rapidly for the periods (2010-2018). Findings show that, housing provision (residential), business purpose (commercial) and educational (institution) are the major causes of land use change in the study areas. To reduce the effect of land use expansion in the study areas, policy measures were recommended which include regulating the growth and spread of development, regional development programs. In our opinion, the information provided by these technologies could help city planners and policy makers to attain and sustain future urban development.展开更多

It also suggests that the government use multi-level public housing rent to substitute for single-level in order to make the policies for public housing rent more just, equitable and effective.展开更多

This paper is based on a literature study and a web-based semi-structured thematic interview, in which the Finnish water utility managers identified the current status of their utilities’ asset management. The water services professionals are extremely worried that, by and large, water and sewage networks are still deteriorating, although the networks are nowadays rehabilitated more systematically. The survey reveals that although most of the surveyed utilities have adopted several processes and sub-processes of asset management, and a few utilities are even using some asset management guides, as a whole a strategic approach to and a comprehensive framework for optimized management of physical assets are not practiced. Therefore the development and introduction of specific asset management guidelines should be considered. In order to support successful usage of the asset management framework, the basic concepts and principles of engineering asset management should be included in educational and professional development programs, in particular at the university level.展开更多

These services are interdependent, as water is an integral part of electric-power generation; it is used directly in hydroelectric generation, and it is used extensively for cooling and emissions scrubbing in thermoelectric generation. Energy is also an integrated part of water services, as satisfying water needs for supply, purification, distribution, and treatment of wastewater requires energy sources. Water and energy utilities are however regulated without a specific focus on the interdependency of the two sectors and the possibilities to ensure sustainable use of the resources and reduction of greenhouse gasses by a better coordination. The article explains the possibilities of sustainable consumption and production of energy in the water utilities. It highlights EU legal framework that makes coordination at national level possible, and it gives examples and concludes--on the obstacles for the water utilities＇ future as energy-smart utilities that exist at the national level in Denmark.展开更多

The interest in this issue arises for various reasons, from the growing economic significance of the sector at a national level, measurable in terms of production value and the number of operators involved, to the spread of outsourcing policies, liberalization and privatization, and the use of the standard cost to establish the level of funding. In the field of public utilities, until a few years ago, the concept of control was intended only in a ＂bureaucratic＂ sense as the capacity to fulfill the formal obligations linked to the strong regulatory context, ignoring aspects that have become fundamental today, such as economy, efficiency, and effectiveness of management. The approach used is deductive and the study ends with the presentation of the possible implications of the use of standard cost and the presentation of an application hypothesis of a balanced scorecard （BSC） for local public transport （LPT）.展开更多
