التجزئات البيئية السكنية كبديل لتعمير مستدام

Abstract

Urban projects within the framework of sustainable development have become one of the most important priority issues in the policy of the Algerian state and in the world. The accelerated urban process in the light of economic crises and perceived population growth, with state attempts to adopt an urban policy that meets the requirements of these conditions, However, on the ground, several problems stemming from previous policies have arisen. Moreover, due to the growing demands, which are not aligned with the pace of adequate response to housing and urban planning problems. The sustainability of residential subdivisions stems from the sustainability of urbanism and cities within the principles of sustainable development adopted by most countries, in response to a global awareness of environmental risks that spare no one. This situation has led actors in urban planning to adopt the principles of sustainable development with the aim of developing the urban area by integrating these principles into planning methods, and particularly focusing on neighborhoods to make them sustainable. Our objective through this work is to provide a tool to evaluate the performance of neighborhoods, which contributes to effective decision-making in this new approach of planning and intervention in urban areas until it is sustainable. The 351 residential subdivisions, in the city of Biskra, were selected as representative of all residential subdivisions with similar problems, and aspire to sustainability. Concretely, the study of this area consisted of examining the theoretical aspect and results of the reconstruction tools and comparing them to reality, as well as evaluating their sustainability using the HQER approach and tools. The results of this rigorous assessment are a realistic diagnosis of several deficiencies, including the land use pattern of the area and new subdivisions. This shows that urban policy cannot keep pace with its modern aspirations. This diagnosis allowed us to highlight several solutions and recommendations including simulation to integrate the solar panel system to reduce energy consumption and other practical ways to make the subdivision sustainable, also to meet the aspirations of the population and its awareness of the need to change reality and behaviour for a better life. Finally, sustainable urban development depends on the integration of urban environmental standards into existing residential developments, taking into account the climate and social and cultural characteristics of the local community.
