In the late 1960s, the Islamic Republic of Pakistan’s capital shifted from Karachi to Islamabad, officially named Islamabad Capital Territory (ICT). In this aspect, the ICT is a young city, but undergoing rapid expansion and urbanization, especially in the last two decades. This study reports the measurement and characterization of ICT land cover change dynamics using Landsat satellite imagery for the years 1976, 1990, 2000, 2010, and 2016. Annual rate of change, landscape metrics, and urban forest fragmentation spatiotemporal analyses have been carried out, along with the calculation of the United Nations Sustainable Development Goal (SDG) indicator 11.3.1 Land Consumption Rate to the Population Growth Rate (LCRPGR). The results show consistent increase in the settlement class, with highest annual rate of 8.79% during 2000–2010. Tree cover >40% and <40% canopy decreased at an annual rate of 0.81% and 0.77% between 1976 to 2016, respectively. Forest fragmentation analysis reveals that ‘core forests of >500 acres’ class decreased from 392 km2 (65.41%) to 241 km2 (55%), and ‘patch forest’ class increased from 15 km2 (2.46%) to 20 km2 (4.54%), from 1976 to 2016. The LCRPGR ratio was 0.62 from 1976 to 2000, increasing to 1.36 from 2000 to 2016.

Urban blue and green space is a key element supporting the normal operation of urban landscape ecosystems and guaranteeing and improving people's lives. In this paper, 97.1k photos of Beijing were captured by using web crawler technology, and the blue sky and green vegetation objects in the photos were extracted by using the Image Cascade Network (ICNet) neural network model. We analyzed the distribution characteristics of the blue–green space area proportion index and its relationships with the background economic and social factors. The results showed the following. (1) The spatial distribution of Beijing's blue–green space area proportion index showed a pattern of being higher in the west and lower in the middle and east. (2) There was a positive correlation between the satellite remote sensing normalized difference vegetation index (NDVI) and the proportion index of green space area, but the fitting degree of geospatial weighted regression decreased with an increasing analysis scale. (3) There were differences in the relationship between the housing prices in different regions and the proportion index of blue–green space, but the spatial fitting degree of the two increased with the increase of study scale. (4) There was a negative correlation between the proportion index of blue–green space and population density, and the low-population areas per unit blue–green space were mainly distributed in the south of the city and the urban fringe areas beyond the Third Ring Road. The urban blue–green space analysis that was constructed by this study provides new aspect for urban landscape ecology study, and the results proposed here also provide support for government decision-makers to optimize urban ecological layouts.

As destination of choice for many short-term study abroad programs, Berlin offers students of German language, culture and history a number of sites richly layered with significance. The complexities of these sites and the competing narratives that surround them are difficult for students to grasp in a condensed period of time. Using approaches from the spatial humanities, this article offers a case study for enhancing student learning through the creation of digital maps and itineraries in a campus-based course for subsequent use during a three-week program in Berlin. In particular, the concept of deep mapping is discussed as a means of augmenting understanding of the city and its history from a narrative across time to a narrative across the physical space of the city. As itineraries, these course-based projects were replicated on site. In moving from the digital environment to the urban landscape, this article concludes by noting meanings uncovered and narratives formed as we moved through the physical space of the city.

Fleurs Du Mal

Baudelaire refers in his first essay on Théophile Gautier (1859) to the ‘fraîcheurs enchanteresses’ and ‘profondeurs fuyantes’ yielded by the medium of watercolour, which invites a reading of his unearthing of a romantic Gautier as a prescription for the ‘watercolouring’ of his own lyric. If Paris's environment was tinted black as a spiking population and industrial zeal made their marks on the metropolis, Baudelaire's washing over of the urban landscape allowed vivid colours to bleed through the ‘fange’. In his early urban poems from Albertus (1832), Gautier's overall tint of an ethereal atmosphere as well as absorption of chaos and din into a lulling, muted harmony establish the balmy ‘mise en scène’ that Baudelaire produces at the outset of the ‘Tableaux parisiens’ (Les Fleurs du mal, 1861). With a reading of Baudelaire's ‘Tableaux parisiens’ as at once a response and departure from Gautier, or a meeting point where nostalgia ironically informs an avant-garde poetics, I show in this paper how Baudelaire's luminescent and fluid traces of color in his urban poems, no matter how washed or pale, vividly resist the inky plumes of the Second Empire.

The City

Writers of the early nineteenth century sought to find new ways of writing about the urban landscape when first confronted with the phenomena of London. The very nature of London's rapid growth, its unprecedented scale, and its mere difference from any other urban centre throughout the world marked it out as demanding a different register in prose and poetry. The condition of writing the city, of inventing a new writing for a new experience is explored by familiar texts of urban representation such as by Thomas De Quincey and William Wordsworth, as well as through less widely read authors such as Sarah Green, Pierce Egan, and Robert Southey, particularly his fictional Letters from England.
