“…In recent years, the spatial correlation in ES seems to be an appealing issue gaining widespread attention and possessing uncertainties that require further explanation. Degefu et al (2021) confirmed the spatial dependence and spatial autocorrelation of ESVs in Ethiopia [7]. Therefore, we attempt to consider spatial heterogeneity in scenario analysis.…”

“…All ESs are widely recognised as provision, regulation, maintenance and cultural and recreational services, which are important for the well-being and sustainable development of humans [3][4][5]. In return, the demand for social and economic advancement is actively transforming the regional landscape, thereby affecting ESs [6,7]. The comprehension of linkages among ESs, landscape pattern and socio-economic development help elucidate the driving mechanism underlying spatio-temporal ES changes, thus leading to additional pragmatic decisions on ecosystem management [8].…”

Humans benefit from ecosystem services (ES) and profoundly influence the ecosystem in rapid urbanisation and large-scale urban sprawl contexts, especially at the landscape level. However, the impacts of landscape pattern, the driving mechanism of sub-ES and the spatially explicit regional optimisation, have been largely ignored. In response, to the present paper explores two primary aspects: the relationship among ES, landscape pattern, urban income and agricultural output, and the regional governance of optimised ES values (ESV), using the Wuhan urban agglomeration as a case study area. The survey method is employed in obtaining the adjusted magnitude matrix of land use and ecosystem services. Spatial regression analyses are conducted on each ES, including food provision, climate regulation and soil maintenance, with socio-economic indicators and landscape pattern index as explanatory variables. Finally, geographically weighted regression and scenario analyses are conducted on each sub-ESV to generate adjusted coefficients in each county for ESV regulation. The results show that urban per capita disposable income and agricultural output significantly contribute to ESV change, with the former being negative and the latter being positive. A highly aggregated landscape also produces reduced ESV, particularly in soil maintenance and gas and climate regulation. We summarise the ESV in 2020 and in the period after adjustment in different administrative counties. Provision, regulation and culture ecosystem benefits substantially increase when attempts are made to lower the landscape aggregation pattern by 1%. In general, counties and county-level cities have the largest ESV, with food provision as the optimum ecosystem benefit. Districts in the capital city show an immense growth in provision and regulation, and county-level cities show the highest growth rate in cultural service. Integrating the landscape pattern into characterising and optimising ES, provides references for regional governance on land-use planning and socio-economic development, which is vital to sustainable regional development.

“…The resulting proximity impacts the provision of utilities and technology transfer [47,61]. The expansion of peri-urban informal occupation is associated with processes of landscape change that result in diverse degrees of density and patterns of occupation, successively converting agricultural land of low-intensity use into open space and built-up space [91]. It can happen in a somewhat unorderly way, or in "inter-fingering" patterns, alternating agriculture and settlement [38] (p. 137), or they may result in ordered and organized settlements that are still informal, or in gated communities [129].…”

“…The trend in spatial planning is to move from master plans to participatory, multi-layered, holistic, integrated, comprehensive, and flexible strategic plans that are based on quantification of resource expansion and degradation and account for changes in context and opportunities [37,39,154]. The plans resort to adequate data and imagery for different layers [60,91,145] and are coproduced with local knowledge [52,145]. Such strategic plans are expected to promote resilience and natural hazard risk management and realistically balanced socioecological services [91,93].…”

The study of peri-urbanization attracted attention in the final quarter of the 20th century, due to the pace it acquired worldwide and the implication that urbanization and overall settlement patterns have on social sustainability and development. Theoretical and conceptual achievements are remarkable. Multi-country collaboration has produced a growing body of research on sustainability and peri-urban settlements. There is a lack, however, of a review of the practices of peri-urban informal settlements, the predominant mode of urban expansion, mainly in developing and rapidly urbanizing regions of the world. The purpose is, then, to systematize, from recent literature, the knowledge of the context, challenges, and practices, as well as their impacts and potential courses of action, to ensure sustainability in human–natural complex of the territory beyond urban cores, suburbs, or slums. A systematic review approach was adopted, for articles published in reputable journals, with support of previous reviews, books, and reports. A pragmatist combination of content analysis and critical review identified core topics and highlighted contrasting views. An analytical framework is proposed. Four categories—drivers, challenges and practices, impact, and future trends—are proposed as an adequate approach to systematizing the literature. The review finds that the practices focus on service and resource provision, on regulations to approximate informal to formal institutions, and on an economy founded on the resource base and service provision. This review provides insights on future trends and research topics.
