PurposeIt has been widely recognised that the participation of residents is a significant issue in contemporary urban heritage conservation. However, studies confirm that the reasons behind residents' engagement are still difficult to assess, particularly in emerging countries. This paper aims to evaluate the factors that incite or prevent residents from participating in built heritage rehabilitation in the old city of Constantine, by applying the motivation-opportunity-ability (MOA) model.Design/methodology/approachA questionnaire-based survey was used to collect information from the residents. The collected data were then analysed using the structural equation model (SEM).FindingsThe findings show that the most significant factors affecting residents' participation were related to their motivations and abilities. Interestingly, factors related to the opportunities did not influence participation. Thus, autonomous rehabilitation according to the residents' motivation and abilities is more likely to be adopted.Research limitations/implicationsThese findings are limited to the selected sample, and some variables have been eliminated through the SEM analysis.Originality/valueHowever, as a first attempt to study residents' participation in built heritage rehabilitation in Constantine, the paper proposes a different perspective for assessing participation by considering its means and ends simultaneously. The paper also provides guidance to local decision-makers to improve the legal framework by implementing factors that encourage residents' involvement in sustainable heritage management.

Abstract-This paper aims at examining the role civil societies in waste management in Skikda and evaluating their implications and results. This study provides the information needed to evaluate the rate of their participation and the ways to improve it. The data for this study were collected through a survey questionnaire conducted on the environmental associations of Skikda. The survey took into account a variety of criteria including the frequency of participation of the association, the theme(s) they focus on, the distribution of their efforts, the utilized tools, etc. The quantitative data gathered are then analyzed using Statistical Package for Social Sciences (SPSS). Finally, the results show a passive participation of associations in waste management on several levels.

Dans les pays du Maghreb, les centres historiques arabo-musulmans (les médinas) représentent de grandes valeurs patrimoniales, sociales et économiques. Elles marquent l'histoire du peuple, et préservent les caractéristiques du mode de vie des ancêtres, ce qui représente des opportunités pour un tourisme culturel durable. A cet égard, la vieille ville de Ténès, édifiée au 10ème siècle par les marins andalous pour être un souk, a pu préserver son aspect médinois pendant plusieurs siècles, quoique son caractère commercial attractif et identitaire ait fortement dégradé sous l’effet des mutations socio-économiques. Le centre commercial de la médina et son cœur battant a subi plusieurs dégradations. Le présent travail a pour objectif d’analyser l’état des lieux de cet espace et de présenter des scénarios de sa revitalisation dans le cadre du tourisme culturel durable, à la lumière des expériences maghrébines, et des politiques urbaines nationales, territoriales et locales.

It becomes necessary to develop an urban climate diagnostic tool, in order to improve the urban planning approaches, as well as the conception of new projects at the micro-scales. The development of this tool requires an urban understanding of each block. This study aims to classify the El Harrachblocks, by applying the "Local Climate Zones" approach, and using the Geographic Information System (GIS) methods. Thus, within the framework of this study, we will test the adaptability of this approach on El Harrach. The results show that this approach seems to be in agreement with our aims; while taking into account certain particular conditions. It will also allow us to provide the precise details on the urban knowledge of each block, which could beused as a basis for strategic studies, that help the actors of the agglomeration in the implementation, the monitoring and the evaluation of environmental and energy policies.
