“…Addition of natural organic substrates (e.g., turf, peat, or compost) increases SOC stocks in urban soils. However, intensive decomposition by microorganisms can result in 30–40% loss of C in these materials as CO 2 , within just a few years (Shchepeleva et al, ; Vasenev, Epikhina, Fatiev, & Prokhorov, ). Heating industries and fossil fuel combustion are important BC sources (Preston & Schmidt, ; Rawlins et al, ).…”

Urban soils as hot spots of anthropogenic carbon accumulation: Review of stocks, mechanisms and driving factors

Urban soils and cultural layers may accumulate C over centuries and consequently large C stocks may be sequestered beneath cities. Processes and mechanisms leading to high C accumulation in urban soils remain unknown. Data on soil organic carbon (SOC), soil inorganic carbon (SIC), black (pyrogenic) carbon (BC), and nitrogen contents and stocks in urban soils were collected from 100 peer‐reviewed papers. The database (770 data points for SOC, SIC, and BC stocks from 116 cities worldwide) was analysed considering the effects of climate and urban‐specific factors (city size, age, and functional zoning) on C stocks. The processes of C accumulation specific for urban soils were analysed, and C sequestration rates were assessed. For the wide range of climatic conditions, total C content in urban soils was 1.5–3 times higher, and C accumulation was much deeper compared with natural soils, resulting in 3–5 times larger total C stocks. Urban SOC stocks increased with latitude, whereas SIC stocks were less affected by climate. City size and age were the main factors explaining intercity differences in C stocks. The intracity variability of C and N stocks was dominated by functional zoning: Large SOC and N stocks in residential areas and large SIC and BC stocks in industrial zones and roadsides were consistent across all climates and for cities of various sizes and ages. Substantial amounts of SOC, SIC, and N are sequestered in the subsoils, cultural layers, and sealed soils, underlining the importance of these hidden stocks for C assessments. Long‐term С input from outside the cities and associated C accumulation coincided with upward soil growth of ~50 cm per century, and continuous accumulation of 15–30 kg C/m2 per century in urban soils and cultural layers. We conclude that, despite the relatively small area of cities, urban soils are hot spots of long‐term soil C sequestration worldwide, and the importance of urban soils will increase in future with global urbanization.

“…Establishing an active plant community as an internal source of organic matter and as a driver of multiple biotic and abiotic interactions is also important (Deeb et al, 2016b;Jangorzo et al, 2018Jangorzo et al, , 2014Pey et al, 2013aPey et al, , 2014.

Abstract. With the rise in urban population comes a demand for solutions to offset environmental problems caused by urbanization. Green infrastructure (GI) refers to engineered features that provide multi-ecological functions in urban spaces. Soils are a fundamental component of GI, playing key roles in supporting plant growth, infiltration, and biological activities that contribute to maintenance of air and water quality. However, urban soils are often physically, chemically or biologically unsuitable for use in GI features. Constructed Technosols (CT), consisting of mixtures of organic and mineral waste, are man-made soils designed to meet specific requirements and have great potential for use in GI. This review covers (1) current methods to create CT adapted for various GI designs and (2) published examples where CT have been used in GI. We address the main steps for building CT, the materials and which formulae that should be used to design functional CT, and the technical constraints to using CT for applications in parks, streetside trees, stormwater management, urban farming, and abandoned land. The analysis suggests that the composition and structure of CT should and can be adapted to available wastes and by-products and to future land use and environmental conditions. CT have a high potential to provide multiple soil functions in diverse situations and to contribute to greening efforts in cities (and beyond) across the world.

“…Carbon pools in urban soils are comparable with or exceed those in natural soils [90,103], but a significant portion of these pools is represented by easily mineralizable carbon compounds [99]. The relationship between carbon stocks and СО 2 emissions in UTSs varies for different land uses and types of surfaces (urban lawns, parks, forest parks, specially protected areas) [94].…”

A review of Russian and foreign approaches to analyze and assess the ecological and socioeconomic role of urban and technogenic soils is made in the context of the two popular concepts: the ecological functions of soils and ecosystem services. The modern definitions, classification, and evaluation of ecosystem services and their relationships with soil functions are considered both in general and in relation to urban and technogenic soils. Despite some methodological differences, the work shows that the concepts are closely related, and their joint use is highly promising. Three practical examples for the cities of Moscow, Hangzhou, and Hong Kong show a consistent transition from the analysis of soil properties and functions to the assessment of ecosystem services and decision making in engineering, urban improvement, and sustainable urban development.
