“…This inconsistency is exemplified by the urban plan phase I extension and phase IV-A designed to provide urban functions, including residential, industrial, town park, neighborhood and district centers, and educational areas within the land use initially designated for productive forestry and intensive agriculture by the regional plan [66][67][68]. The loss of land use designated for productive forestry and intensive agriculture by urban development may be associated with the loss of ecosystem services (e.g., food, fuel, and fiber) provided by such land use [9,[78][79][80][81]. However, while the urban plan phase I extension has been implemented, the phase IV-A has not been implemented, implying that the urban functions (e.g., industrial, town park, neighborhood, and district centers) have not been achieved in those conflict areas, leaving the areas with haphazard urban expansion patterns.…”

Land use planning as strategic instruments to guide urban dynamics faces particular challenges in the Global South, including Sub-Saharan Africa, where urgent interventions are required to improve urban and environmental sustainability. This study investigated and identified key challenges of land use planning and its environmental assessments to improve the urban and environmental sustainability of city-regions. In doing so, we combined expert interviews and questionnaires with spatial analyses of urban and regional land use plans, as well as current and future urban land cover maps derived from Geographic Information Systems and remote sensing. By overlaying and contrasting land use plans and land cover maps, we investigated spatial inconsistencies between urban and regional plans and the associated urban land dynamics and used expert surveys to identify the causes of such inconsistencies. We furthermore identified and interrogated key challenges facing land use planning, including its environmental assessment procedures, and explored means for overcoming these barriers to rapid, yet environmentally sound urban growth. The results illuminated multiple inconsistencies (e.g., spatial conflicts) between urban and regional plans, most prominently stemming from conflicts in administrative boundaries and a lack of interdepartmental coordination. Key findings identified a lack of Strategic Environmental Assessment and inadequate implementation of land use plans caused by e.g., insufficient funding, lack of political will, political interference, corruption as challenges facing land use planning strategies for urban and environmental sustainability. The baseline information provided in this study is crucial to improve strategic planning and urban/environmental sustainability of city-regions in Sub-Saharan Africa and across the Global South, where land use planning faces similar challenges to address haphazard urban expansion patterns.

“…Many scholars have widely discussed these processes and demonstrated that urban expansion is the most crucial factor that results in various impacts on the structures and functions of natural ecosystems at multi-perspectives [18,[24][25][26]. On the one hand, urban expansion brings about the large-scale population movement and pollutant emission, and the accumulation of these effects seriously undermines the exchange and connection of energy flow and material flow within the whole ecosystem [27]. When they exceed the ecosystem carrying capacity, the health and sustainability of ecosystems will be endangered and will finally result in ecological disasters [28,29].…”

Exploring impacts of urban expansion on ecosystem services has become a hot topic for regional sustainable development, while analyzing the ecological effects of urban expansion forms under different expansion intensities and city sizes is relatively rare. Therefore, taking a typical urban agglomeration, Shanghai-Hangzhou Bay Urban Agglomeration, as a case study, this study first analyzed the dynamics of urban expansion forms (leapfrogging, edge-expansion, and infilling) and four critical ecosystem services (carbon sequestration, food supply, habitat quality, and soil retention) in three periods from 1990 to 2019. The multiple linear regression model and zonal statistics analysis model were used to quantitatively identify the impacts of urban expansion forms on ecosystem services, taking into account different expansion intensities and city sizes. The results showed that the urban expansion trend in the study area experienced a morphological change from integration to diffusion and then to integration in 1990–2019; edge-expansion was the dominant expansion form. Food supply decreased continuously while other ecosystem services had fluctuating changes, and they all had spatial heterogeneity. The leapfrogging, edge-expansion, and infilling all had negative impacts on ecosystem services, and among them, the edge-expansion intensity had the highest influence degree in the early expansion, and the leapfrogging intensity occupied the dominant position in all influences with the expansion of urban scales. For different city sizes, the impact of edge-expansion in large-scale cities was greater than in small-scale cities in the early expansion, and the impact of leapfrogging in large-scale cities exceeded the edge-expansion in the subsequent expansion. These findings will help further understand the influential mechanisms between urban expansion and ecosystem services and provide a scientific basis for formulating reasonable urban planning.

“…We hope to establish a bridge between soil science and social science in order to expand the scope of existing research. In addition, the peri-urban areas are a focus of the government and researchers in the rapid process of industrialization and urbanization in China and global studies [59][60][61][62]. These policy implications are of great significance to the protection of SQ in the region and the sustainability of PUA.…”

The driving mechanism of soil quality (SQ) has important implications for arable land protection, sustainable agricultural development and ecological environment conservation. This study builds a “perception–response” theoretical framework to investigate how farmers’ land use behavior may affect SQ from the temporal and spatial perspectives. Based on soil sampling data, farmer survey data and socioeconomic statistical data collected in a typical peri-urban area of northeast China, geo-statistical analysis and econometric models have been applied to examine the effect of farmers’ land use behavior (FLUB) on SQ. The results show that during 1980–2010, the target of FLUB has been shifted from “grain output maximization” to “grain output and profit maximization” and then to “profit maximization”. The FLUB, including land use pattern, land use degree and land input intensity, also show obvious differences in space. These differences result in distinct impacts on the variation of SQ in time and space. Generally, the soil organic matter (OM) tends to decline, the available nitrogen (AVN) and available phosphorus (ANP) tend to rise, while the available potassium (AVK) increases after an initial decline. Moreover, the further distance from the city center, the greater the spatial variation of SQ in space. These findings are not only helpful from a theoretical and practical significance for policy-makers to improve SQ in the outskirts of metropolitan areas, but also make an important contribution to the sustainable development of peri-urban agriculture (PUA).
