“…Such degradation of ecosystems and freshwater species has been extensively reported in the CO-NUS and it is expected to occur in other areas across the globe where the use of land and water is changing and population is growing (Fitzhugh & Richter, 2004). As a result, it is crucial to gain a better understanding of the dynamics of interaction between urbanization and surface water, and in particular how the presence of human settlements influences the progressive loss of surface water resources, to find a balance between urban planning and water management policies that ensure water conservation and ecosystem protection (Hoekstra et al, 2018;McDonald, Douglas, et al, 2011;McGrane, 2016;Paiva et al, 2020;Vörösmarty et al, 2010;Wada et al, 2016).…”

Urban development affects the distribution of surface water through direct water abstraction from springs and rivers (Flörke et al., 2018), groundwater exploitation turning into increased infiltration (Wada et al., 2012), land drainage supporting agricultural development (Smedema et al., 2000), and increased evaporation induced by the urban heat island effect (Zhou et al., 2015). In turn, a reduction in the extent of surface water bodies close

In order to effectively anticipate the implications of urbanisation for Brazil's species diversity in the future, as well as in urban ecosystems across the globe, an improved understanding of connectivity in urban landscapes will be instrumental.…”

Increasing urban expansion has resulted in the decline of many natural and semi-natural communities globally. However, the connectivity and genetic structure of species that survive in these urban landscapes has received little attention, especially with regard to epiphytic plants. The aims of this study were to 1) investigate how an urban landscape can impact the connectivity and genetic structure of Tillandsia recurvata, L., a highly abundant and widely distributed atmospheric epiphyte; to 2) understand what the driving landscape factors are that affects connectivity and structure; and to 3) discuss how urbanisation can affect genetic structure in epiphytes. A total of 288 T. recurvata individuals were sampled across 65 trees throughout the city of Alfenas in South-East Brazil. We designed seven novel microsatellite markers and used four cross-amplified loci to determine the basic genetic structure of T. recurvata. All populations showed high global spatial genetic structure (SGS) and population differentiation. The high SGS of T. recurvata indicated low connectivity between urban populations, with strong evidence to suggest that this was the result of small population size and genetic drift. Pasture trees outside of the urban landscape are likely to be an important source of gene flow to isolated urban epiphyte populations. This study represents an important step towards understanding epiphyte population structure within urban landscapes. Low connectivity across urban landscapes is likely to benefit epiphytes such as T. recurvata due to their adaptability and high tolerance; suggesting a bleak future for many other more sensitive epiphyte species under predicted urbanisation globally.

“…Rapidly urbanising populations around the world are placing increased pressure on the environment, the process of land use planning and the management of resources [1][2][3]. An improved understanding of the speed and scale of development and the structure evolution of cities is therefore essential to assess the impacts of urbanisation and for the development of policies directed towards resource efficiency and sustainability.…”

Using Satellite Data to Analyse Raw Material Consumption in Hanoi, Vietnam

et al. 2021

In this work, we provide an innovative route for analysing urban expansion and population growth and their link to the consumption of construction materials by combining satellite data with material consumption analysis within the Hanoi Province (Vietnam). Urban expansion is investigated with the use of landcover maps for the period 1975–2020 derived from satellite. During this period, artificial surfaces and agricultural areas have increased by 11.6% and 15.5%, respectively, while forests have decreased by 26.7%. We have used publicly available datasets to calculate and forecast the construction materials consumption and measure its statistical correlation with urban expansion between 2007 and 2018. Our results show that official figures for sand consumption are currently underestimated, and that by 2030, steel and sand and gravel consumption will increase even further by three and two times, respectively. Our analysis uses a new method to assess urban development and associated impacts by combining socio-economic and Earth Observation datasets. The analysis can provide evidence, underpin decision-making by authorities, policymakers, urban planners and sustainability experts, as well as support the development of informed strategies for resource consumption. It can also provide important information for identifying areas of land conservation and ecological greenways during urban planning.
