This study examines the concept of sustainability and livability at the neighborhood level in a low-density city such as Doha. In its current form, Metropolitan Doha, Qatar’s capital and where 80% of the population resides, is neither sustainable nor ranked highly in many city livability indices of international cities, although Qatar aims to become a truly sustainable state as envisioned in its Qatar National Vision (QNV) 2030 and endorsed in its National Development Strategies 2012 and 2018. Doha remains a fractured city; its rapid growth has led to unrestrained, extensive urban sprawl with high dependency on private transportation mainly by large SUVs, continually instigated by the absence of public transportation. Doha is also a relatively low-density city where the main driver of its urban sprawl is the inhabitants’ deep-set desire for privacy, and hence, home ownership of single-family detached villas, which have become the predominant residential building-block of neighborhoods with little to no provisions of in-neighborhood community services and amenities such as basic shopping, health, education, and recreation. Consequently, this urban form has resulted in long and frequent commutes for individuals and families, increasing the number of vehicles in traffic almost every hour of every day, traffic congestion, high transportation-related CO2 emissions, additional expenses, and loss of quality family time, among several other environmental, social, and economic sustainability impacts. The findings of this study, which are based on a behavioral survey, illustrate the residents’ views on neighborhood improvement and changes in the transportation modes, as well as their willingness to change their habits for the benefit of common and future generations.

This study focuses on the significance of neighborhoods in a city as the smallest self-sufficient urban units akin to nuclear families in the larger society. Thus, improvements to the neighborhood form can improve livability, maximize walkability, and better the overall life quality of city inhabitants, which, in turn, advance a city’s overall environmental and social sustainability profile. The physical form (arrangement) and density of neighborhoods are primarily shaped by land ownership regulations, transportation, and communication means. The development of smart technology, especially in the fields of transportation and communication, has led to the reconsideration of some of sustainable urban form concepts such as neighborhoods. Low-density cities like Doha, Qatar can become both sustainable and livable, creating the basis for a sustainable city. First, this paper presents a critical review of Doha’s neighborhoods and advanced transport and communication technologies, in addition to the integration of these technologies with the physical form of neighborhoods. Then, the paper discusses the influences of such technologies on the future sustainability of the city of Doha and its neighborhoods. This investigation is based on a Delphi study to address the characteristics of a neighborhood and to identify two paradigms of ‘good’ design practice.

The construction industry is a major generator of waste. There are many challenges associated with implementing sustainable methods to manage construction waste. While the construction industry in the State of Qatar has been adopting plenty of progressive practices, waste management, especially of concrete waste, has not advanced notably. In addition to the limited supply of limestone suitable for use as natural aggregate for concrete production in Qatar, the ability to recycle and reuse concrete waste is critical to reducing environmental impacts to meet national, regional and global environmental goals. Therefore, this research aims to identify the current status of concrete waste management practices in construction projects in Qatar exemplified by a local case-study project. Concrete waste was particularly monitored over the span of the construction stage of a large research and development facility in Qatar, benchmarking trends and practices on a certified “green” building. In response, this study addresses key challenges to concrete waste recycling and reuse to then recommend opportunities of advancements in local concrete waste management and reuse.

Present a model that remedies root causes of sustainability and livability issues as they are not tackledin Qatar’s current urban development plans with relation to the most basic unit of urbanism: theneighborhood. The developed model presents modifications to Al-Markhiya in short-, medium-, andlong-term implementation phases that include typical characteristics applicable to any Dohaneighborhood so that they could be easily adopted by municipalities as well as local communities.Developed model received favorable feedback when presented to a group of environmental and urbanplanning experts at the frontlines of developing and updating Qatar National Master Plan and detailsof urban planning regulations to poll their views on its applicability for greater. This study is expectedto influence decision makers in Qatar to pay the required attention to the enhancement ofneighborhood sustainability and livability. This model may be the stepping stone to future strategiesand plans of refurbishment as the next national goal post the World Cup to be hosted in 2022.
