The peripheral fringe area of cities comes under the peri-urban category, where rural areas are forced to assimilate with urban areas. Sustainable development of fast growing peri-urban regions is a big challenge for the various agencies and authorities concerned throughout the world. The geo-social dynamics of assimilation of the rural-urban spatial fringe are a new concept to understand; its significance in planning and management of the sustainability of environment, ecology of the area in particular the socio-economic facet of sanitation and health. The quantification of the sustainability of the development establishes by geo-social degradation. There are several geo-social buffer zones, which have been specified to understand the existing peri-urban regions state of development and evolve the strategies for betterment. Geo-social aspect of peri-urban regions development is an interdisciplinary approach.

Wetlands can only be well managed if their spatial location and extent are accurately documented, which presents a problem as wetland type and morphology are highly variable. Current efforts to delineate wetland extent are varied, resulting in a host of inconsistent and incomparable inventories. This study, done in the Witbank Dam Catchment in Mpumalanga Province of South Africa, explores a remote-sensing technique to delineate wetland extent and assesses the seasonal variations of the inundated area. The objective was to monitor the spatio-temporal changes of wetlands over time through remote sensing and GIS for effective wetland management. Multispectral satellite images, together with a digital elevation model (DEM), were used to delineate wetland extent. The seasonal variations of the inundated area were assessed through an analysis of monthly water indices derived from the normalised difference water index (NDWI). Landsat images and DEM were used to delineate wetland extent and MODIS images were used to assess seasonal variation of the inundated area. A time-series trend analysis on the delineated wetlands shows a declining tendency from 2000 to 2015, which could worsen in the coming few years if no remedial action is taken. Wetland area declined by 19% in the study area over the period under review. An analysis of NDWI indices on the wetland area showed that wetland inundated area is highly variable, exhibiting an increasing variability over time. An overlay of wetland area on cultivated land showed that 21% of the wetland area is subjected to cultivation which is a major contributing factor to wetland degradation.

The Upper Kharun Catchment (UKC), which is part of the new State Chhattisgarh formed in 2000, features considerable population growth, expansion of urban areas and dynamic changes in irrigation infrastructure as well as irrigation practices (spatial extension, temporal intensification, increasing use of groundwater as source) for meeting the increasing food demand. Water intensive rice is the major crop of the area. UKC has a comprehensive canal irrigation system which provides the link to water supply from reservoirs fed from areas outside the UKC. However, water provision for irrigation via the canal system for irrigation is restricted to only post-monsoon season. As a consequence, groundwater remains the only source of irrigation water in summer and winter seasons. Improved electricity facilities and subsidy on groundwater pumping have triggered an enormous increase in groundwater withdrawals. Remote sensing satellite images along with ground observed data were used in this study to spatially identify the areas with canal and groundwater irrigation. Results reveal that in 2011, around 50% of the area of the UKC benefits from canal irrigation, whereas 29.8% area is irrigated by groundwater. Around 103 villages in the UKC have no canal infrastructures. 216 villages in UKC are considered as ‘hotspot areas’ because of high groundwater withdrawal (irrigated area exceeding 75 ha per village), There has been threefold increase in groundwater irrigated area in UKC between 1991 and 2011. The upward trend of groundwater use indicates an alarming situation towards over-exploitation and creates the need to provide and analyze data on the use of groundwater resources in the area in order to detect past and to estimate future trends referring to groundwater withdrawals. These data are a prerequisite for enabling careful and foresightful management of groundwater resources especially at spatially identified hotspot areas towards ensuring sustainable management of this resource.

This paper examines how indigenous peri-urban households in Wa, one of the fastest growing towns in Ghana are adapting to the effects of physical transformation of their environment. By analysing Landsat satellite images and using social research methods, the paper discusses the nature and extent of urban growth, its impact on periurban livelihoods, and the coping strategies of peri-urban households. Findings show that urban land in Wa increased by 5.73 times—from 5.75 km2 in 1986 to 32.93 km2 in 2016 with an annual growth rate of 5.9%. This growth led to the conversion of agricultural lands into residential and other uses. As a result, many indigenous peri-urban households are abandoning agriculture in search for urban-based employment as a safety net. The study recommends partnership between local government and landowners to identify and protect high potential agricultural lands in Wa; modernisation of the land governance and management processes in view of the loss of cultural and spiritual values associated with land; prioritisation of physical and spatial planning at the district level; and equipping indigenous peri-urban households with skills to assist them create sustainable livelihoods to compensate for the loss of their agriculture lands.

Increasing flood risk due to rapid urbanization and climate change calls for improved integration between flood risk management and spatial planning processes to enhance the resilience of cities, including in Egypt. Although much work has been conducted on flood impact in Egypt, the gap in integrating flood risk assessment with spatial planning practices has not been discussed in academia. In practice, flood risk assessment is not mandatory for local-level spatial planning projects in Egypt, resulting in increased flood risk. This study examines the causes of this gap and proposes possible solutions that increase flood resiliency. A mixed-method approach was utilized based on a questionnaire survey with local stakeholders in academic and professional categories. The results reveal reasons for the gap, including issues related to the realization of the role of spatial planning in flood risk reduction, lack of coordination between the authorities responsible for developing the flood hazard maps and the spatial planning authority, availability and accessibility of the required data, and subjectivity of conducted flood analyses. Four key recommendations pertain to building an operational framework for integrating flood risk assessment in spatial planning, improving stakeholder awareness and collaboration, strengthening risk communication, and improving both quality and access to data. These measures will help to overcome the identified difficulties and enhance the integration between spatial planning and flood risk assessment, effectively increasing their flood resilience.

With increasing global challenges such as climate change and urbanisation, it is essential to relook at ingenious ways that water has been managed in the past and continues to be managed. This paper looks at heritage water management systems that have existed for centuries from an exploratory research approach. The ‘mosaic model’ from the landscape ecology scholarship is applied to understand the spatial components and linkages of these systems. The paper starts with the key features of heritage water systems, then moves to establish a close link between green infrastructure and heritage water systems. Finally, we explore a few select cases by applying the mosaic model to understand the heritage water systems. One of these cases is then further demonstrated to provide an insight into the systems and enable its spatial-wise use in the present fabric.
