“…Related to the primary objective, this study aims at developing practical urban greening methods based on relevant concepts as well as exemplary practices: (a) the benefits of urban greening could be maximized by revamping entrenched thinking, practices and inertia; (b) decision makers could move from the conventional to the innovative mode, and adopt an integrated and long-term approach; (c) the entire cradleto-grave spectrum of urban greening demands attention, encompassing plantable sites, planning, design, species assemblage, installation, maintenance, management, governance, and community expectations (Attorre et al 2000;Jim and Chen 2006a); (d) notable gaps in knowledge have been identified for proposed improvement, such as the contribution to regional biodiversity and carbon sequestration (Takahashi et al 2008), and landscape and conservation planning (Jim and Chen 2009a, b); and (e) the framework could provide hints on future research priorities to strengthen the locally-relevant knowledge base and appropriate technology, and to inform management.…”

Urban greening contributes notably to quality of life and ecosystem services in cities. Compact cities in developing and developed countries are commonly beset by greenspace deficit. Based on literature review supplemented by field studies in different cities, a sustainable urban greening strategy is proposed. Urban renewal and new developments without a greening vision could miss the opportunities to bring relief. The public and private sectors can join hands to insert plantable spaces into the urban fabric. Urban greenspaces (UGS) with good connectivity forming a green network to permeate the city constitute the hallmarks of a naturalistic design. Preservation and creation of natural areas with rich biodiversity offer a new dimension to UGS design. Greening benefits could be expressed in economic terms to complement conventional ecological-environmental emphasis. Outstanding trees could receive high-order conservation efforts, and trees in construction sites warrant enhanced protection. Tree transplanting demands an overhaul in concepts and skills. Improving roadside tree planting and maintenance offers a cost-effective way to upgrade the townscape. Ameliorating widespread soil limitations could remove a major hindrance to tree growth. Innovative ideas of development right transfer, street pedestrianization, river and canal revitalization, green roofs and green walls could mobilize hitherto underused plantable resources. Lacking appropriate institutional setup and scientific capability pose intractable bottlenecks. Innovative public policies and greening technologies are needed for sustained improvements. Amalgamating natural and social sciences in a multidisciplinary approach and reinforcing the link between science and public policies could overhaul greening.

“…For instance, area-based total C densities of urban soils at 30-cm depths are reported to be 8.2 kg¨C¨m´2 for turf and 7.9 kg¨C¨m´2 for tree-planted areas in urban parks of Tokyo, Japan [21], 7.3 kg¨C¨m´2 for urban lawns in Fort Collins, USA [37], 5.0-17.2 kg¨C¨m´2 for golf courses in Melbourne, Australia [38], and 4.9-17.5 kg¨C¨m´2 for UGS's and urban forests in Auckland, New Zealand [22,39]. These values are much higher than the range of C densities, also at 30-cm depths, found in this study (1.55-3.02 kg¨C¨m´2; Table 2).…”

“…Because land use, land cover change, and/or urbanization history can all affect UGS soil C [17,[20][21][22], soil C densities in different types of UGS's such as roadside, park, school forest, and riverside were quantified and then compared to vegetation C density and site history. In addition, we reviewed the management of soil C in UGS's to enhance the ecosystem services of C storage.…”

Quantifying and managing carbon (C) storage in urban green space (UGS) soils is associated with the ecosystem services necessary for human well-being and the national C inventory report of the Intergovernmental Panel on Climate Change (IPCC). Here, the soil C stocks at 30-cm depths in different types of UGS's (roadside, park, school forest, and riverside) were studied in three major South Korean cities that have experienced recent, rapid development. The total C of 666 soil samples was analyzed, and these results were combined with the available UGS inventory data. Overall, the mean soil bulk density, C concentration, and C density at 30-cm depths were 1.22 g¨cm´3, 7.31 g¨C¨kg´1, and 2.13 kg¨C¨m´2, respectively. The UGS soil C stock (Gg¨C) at 30-cm depths was 105.6 for Seoul, 43.6 for Daegu, and 26.4 for Daejeon. The lower C storage of Korean UGS soils than those of other countries is due to the low soil C concentration and the smaller land area under UGS. Strategic management practices that augment the organic matter supply in soil are expected to enhance C storage in South Korean UGS soils.

“…(2005) reported that the soil carbon accumulation rate in man−made forests is 0.44 to 1.33 MgC ha yr. Takahashi et al . (2008) reported that the carbon accumulation rate of urban park soils is comparable to, or higher than, that associated with trees in parks (55 MgC ha yr).…”

This paper describes the results of soil surveys conducted to determine the carbon sequestration rate, primarily of the soil, which is one of the categories of revegetation related information to be reported under the Kyoto Protocol. First, the background of the surveys is described, and the framework for further study on soil organic carbon sequestration rates is described for urban parks. Then, based on the results of a 125− sample survey from urban parks around Tokyo that were established in different years, the likelihood of whether urban park soils are carbon dioxide sinks is verified. Finally, the carbon accumulation rate 20 years after park establishment was about 1.20 MgC ha year.
