Heritage studies and historical preservation in Pakistan, which have gained momentum in the past few decades, have been focused primarily on residential, commercial, and religious architecture dating to the British and Mughal eras, leaving aside an important layer of economic and urban history related to the industrialization of major cities. Most industrial buildings are left to decay or are demolished to make space for new development. Based on a literature review of Pakistan’s industrial heritage and site surveys conducted in Pakistan between 2019 and 2021, several industrial facilities were identified that have social, cultural, and economic potential for reuse or retooling to address the problem of inadequate public amenities in urban areas. There is, however, no documentation regarding such sites that is available for use by potential stakeholders. An inventory system is proposed to establish an overview of the industrial heritage in Pakistan (types of sites, current properties, spatial characteristics, significance) and to facilitate the recognition and management of these sites. An “industrial site inventory record” (ISIR) form is proposed to record information about industrial buildings and sites. In addition, an “industrial site statement of significance” (ISSOS) is proposed for use in recording the description, heritage value, and important architectural elements of significant industrial buildings and sites. The proposed inventory system is a step toward the recognition of industrial heritage and its potential for adaptive reuse and contribution to urban regeneration.

On the international level, heritage is considered an essential element for the sustainable development of a country. In South Asian countries such as Pakistan, India, and Bangladesh, historic cities struggle to preserve their built heritage, due to rapid urbanisation and changing contemporary urban and architectural requirements. This contribution elaborates on the effects of urbanisation, and city development on the protected heritage of Karachi, Pakistan. The city developed in the 19th century from a mud-fortified small town along the Lyari river to become one of the busiest ports of the Indian subcontinent under British rule. Karachi has now become a metropolitan city with more than sixteen million inhabitants. Due to the accelerated rate of urbanisation and trade activities, Karachi has become Pakistan’s economic capital, resulting in the oblivion of its historical sites. Most of the city’s historic sites are in a state of dereliction, from over- or under-programming, or even under the threat of demolition. The paper focuses on the present condition of a British-era protected-heritage site through a literature review and fieldwork (mapping, drawing, archival research, interviews, photographic surveys, etc.), carried out during 2019 and 2020. The first author conducted site visits to photograph buildings and interview their users to gather feedback on how they perceive the current state of these buildings. The data were analysed to investigate how many buildings from Karachi’s British era with protected status have been demolished or are at risk of demolition. At the heart of the article is the Saddar Bazar Quarter in Karachi and its historical, social, cultural, and economic importance in the city from the British period until the present. The analysis will lead the discussion on what potential these sites/buildings hold, and how to make their preservation possible and withstand the uncurbed urbanisation and the threat of land development. Through discussion, we will focus on the social, cultural and economic aspects which the area and the buildings from the British period hold, and which can be useful in the future for the continuation of the Saddar Bazaar Quarter (SBQ), the historic urban landscape (HUL) and the heritage buildings.

At the international level, heritage is widely recognised as a critical component of sustainable development. However, in South Asian countries such as Pakistan, India, and Bangladesh, historic cities continue to struggle to preserve and integrate built heritage amid rapid urbanisation, socio-economic transformation, and evolving contemporary urban demands. Heritage places in these contexts are shaped by complex interrelations between collective memory, the built environment, and socio-cultural identity. Yet, conservation practices have been mainly implemented through fragmented, building-by-building approaches that neglect urban-scale coherence and intangible cultural dimensions. This article addresses this gap by examining adaptive reuse as a value-based conservation strategy in historic urban quarters, where heritage serves as both a repository of cultural memory and a catalyst for sustainable, experience-based tourism. Drawing on qualitative fieldwork, heritage value assessment matrices, and doctoral research, this study uses the Saddar Bazaar Quarter in Karachi, Pakistan, as a case study to explore how tangible and intangible heritage values can be systematically integrated into conservation and regeneration processes. The findings demonstrate that heritage-led adaptive reuse, when embedded within a comprehensive urban-scale conservation framework, can sustain everyday socio-cultural practices, reinforce local identity, and enhance the legibility of historic urban environments. Rather than positioning tourism as a primary driver, the study shows that culturally sensitive and community-oriented tourism emerges as an outcome of successful heritage integration, grounded in lived urban experience rather than commodified representation. Based on these insights, the article proposes a value-based integration framework that aligns heritage conservation, adaptive reuse, and sustainable tourism within historic urban quarters. The framework offers transferable methodological guidance for revitalising heritage places and collective memories, while providing policy-relevant insights for heritage governance that support sustainability objectives, community resilience, and inclusive urban regeneration in post-colonial contexts.

The COVID-19 pandemic presented an unprecedented opportunity to assess the environmental effects of reduced anthropogenic activity on urban climates. This study investigates the impact of COVID-19-induced lockdowns on land surface temperature (LST) and the intensity of the surface urban heat island (SUHI) in Nowshera District, Khyber Pakhtunkhwa Province, Pakistan, which is experiencing rapid urbanization. Using Landsat 8/9 imagery, we assessed thermal changes across three periods: pre-lockdown (April 2019), during lockdown (April 2020), and post-lockdown (April 2021). Remote sensing indices, including NDVI and NDBI, were applied to evaluate the relationship between land cover and LST. Our results show a significant reduction in average LST during lockdown, from 31.38 °C in 2019 to 25.34 °C in 2020, a 6 °C decrease. Urban–rural LST differences narrowed from 9 °C to 6 °C. A one-way ANOVA confirmed significant differences in LST across the three periods (F (2, 3) = 3691.46, p < 0.001), with Tukey HSD tests indicating that the lockdown period differed significantly from both the pre- and post-lockdown periods (p < 0.001). SUHI intensity fell from 35.10 °C to 28.89 °C during lockdown, then rebounded to 35.37 °C post-lockdown. The indices analysis shows that built-up and rangeland areas consistently recorded the highest LST (e.g., 35.36 °C and 37.09 °C in 2021, respectively), while vegetation and water bodies maintained lower temperatures (34.68 °C and 32.69 °C in 2021). NDVI confirmed the cooling effect of green areas, while high NDBI values correlated with increased LST in urban areas. These findings underscore the impact of human activity on urban heat dynamics and highlight the role of sustainable urban planning and green infrastructure in enhancing climate resilience. By exploring the relationships among land cover, anthropogenic activity, and urban climate resilience, this research offers policymakers and urban planners’ valuable insights for developing adaptive, low-emission cities amid rapid urbanization and climate change.
