“…The results of gradient changes in carbon stocks in Changzhou in response to urban land use and cover change depend to a considerable extent on the quality of land cover mapping and accuracy of estimated carbon stocks (Muñoz-Rojas et al, 2011). Davies et al (2013) noted that biomass estimates in urban areas are potentially highly variable based on the diverse approaches that have been used to estimate carbon stocks and the errors created by extrapolating these estimates to the city-wide scale.…”

a b s t r a c tEcosystem services in urban areas are regarded as multiple environmental benefits fostered by urban-rural landscapes. A wide range of ecosystem services have been largely affected by land use and cover change in urban areas, leading to significant variation of ecosystem services, such as terrestrial carbon stocks across a gradient of urbanization. Urban areas are critical for terrestrial carbon dynamics owing to both considerable amount of biomass and soil carbon stored in cities and significant losses in carbon stocks from urban land use and cover change. We used Changzhou, a typical fast-growing city in China, as a case study, and estimated biomass and soil carbon stored in land covers using the InVEST model. We also quantified gradient changes in terrestrial carbon stocks in response to urban land use and cover change along two sample transects as a function of distance from the urban center. We found that carbon densities decreased with increasing intensity of urban development. Gradient transect analyses revealed an overall trend of increasing carbon stocks from the urban center to peri-urban areas as a direct result of land use and cover change driven by policy-oriented urban planning, which led to both infilling of empty areas within the urban center and sprawling of urban land toward peri-urban areas. As recent growth trends continue, the expansion of urban land markedly decreased areas previously dominated by green open spaces, making urban land use and cover change and losses in carbon stocks an increasingly important component of regional carbon dynamics. We proposed measures to mitigate these negative effects of urbanization on carbon stocks both for densely built-up areas and for rapidly urbanizing peri-urban areas.

“…The expansion of perennial woody systems such as vineyards and orchards in California has been associated to the accumulation of significant amounts of carbon in their living biomass (Kroodsma and Field 2006). Also in Andalucía, in South Spain, an increase in vegetation carbon stocks between 1956 and 2007 was partially associated to the expansion of permanent crops (Muñoz-Rojas et al 2011).…”

Fruit tree orchards have a historical and economic importance for Mediterranean agriculture, notably in Spain. Fruit tree orchards have the potential to mitigate global warming by sequestrating carbon (C) and providing renewable fuels. Actually, there is few information on the benefits of organic practices. Therefore, we analyzed the greenhouse gas contribution of 42 pairs of organic and conventional perennial cropping systems, including citrus, subtropical trees, other fruit trees, treenuts, vineyards, and olives, using life-cycle assessment (LCA). The assessment was based on management information from interviews and involved the estimation of soil carbon sequestration, specific Mediterranean N 2 O emission factors, and the consideration of coproducts. Results show on average a 56 % decrease of greenhouse gas emissions under organic versus conventional cropping, on an area basis. On a product basis, greenhouse gas emissions decreased by 39 % on average. These findings are explained mainly by C sequestration in soils, which is due in turn to higher C inputs by cover cropping and incorporation of pruning residues.

“…Many studies suggest that LUCs have a significant effect on soil C stock dynamics, since land use types differ in the amount of C stored in soil and vegetation and also in the potential rate of C content change [4,27,42]. According to this research, land use in Fuyang County has undergone intense changes in the past decades, manifesting important consequences for both VC and SOC sequestration.…”

“…However, due to the low spatial resolution of MSS images in 1979, we were unable to classify the vacant land in that year. Moreover, in line with other C assessment studies [26,27], neither built-up land nor water bodies were assumed to have C stock, nor were they considered for C accounting. Following this round of data acquisition, to detect the SOC of cropland, a field survey combined with laboratory work was conducted in 2006, and a total of 875 soil samples measured ( Figure 1).…”

Land use change (LUC) is the most dynamic force in terrestrial carbon stock change, and it is imperative to account for the dynamics of LUC in carbon stock change when forming land use policies. This paper explored the impacts of LUCs on carbon (C) stocks at a county scale and detected changes of soil C stocks within a county-scale land use planning policy. The LUCs within in Fuyang County (eastern China) and Fuyang Land Use Master Planning (FLUMP) (2006)(2007)(2008)(2009)(2010)(2011)(2012)(2013)(2014)(2015)(2016)(2017)(2018)(2019)(2020) were selected for this pilot study. The estimates of C stock changes were examined by compiling vegetation and soil organic C density data from six land use types, and through literature reviews and field surveys. The results showed that LUCs between 1979 and 2006 already caused a vegetation carbon (VC) decrease of 273.44 Gg and a soil organic carbon (SOC) decrease of 771.01 Gg, mainly due to urbanization processes. Further, the FLUMP (2006-2020) is expected to lead to a potential C loss of 25.93ˆ10´3 Mg C ha´1year´1 for vegetation and 27.48ˆ10´3 Mg C ha´1year´1 for soil between 2006 and 2020. As the situation stands, it is urgent to devise rational policies and effective measures to reverse the C loss process.
