The growing number of people living in urban areas implies the need for more sustainable landscape management. The analysis and monitorization of urban areas allows for the quantification and characterization of urban sprawl processes. Currently, new geospatial and statistical databases are being developed in Europe (Urban Atlas and Urban Audit) with up-to-date and homogeneous information on urban areas, easing its comparison and monitorization, as well as the development of tools for computing urban fragmentation metrics by means of these data, such as IndiFrag. In this work, three applications of fragmentation metrics in multiple scales are presented. Firstly, an intra-urban analysis has been conducted by municipalities in Rome in two dates. Secondly, a massive analysis, comparing at the inter-urban level the fragmentation degree for one date and their growth patterns in a sample of 68 European urban areas. Finally, multiple regression models were tested to explore the prediction of socio-economic variables using the fragmentation metrics of the 68 urban areas. The outcomes show that fragmentation metrics for the analysis of morphology, composition, and urban growth, allow for quantifying urban sprawl patterns at intra- and inter-urban levels, facilitating its relation with socio-economic variables.http://dx.doi.org/10.4995/CIGeo2017.2017.6621

Green infrastructure is a strategically planned network of natural and semi-natural areas, including green and blue spaces and other ecosystems, designed and managed to deliver a wide range of ecosystem services at various scales. Apart from the ecological functions, green infrastructure, as a planning tool, contributes to social and economic benefits, leading to the achievement of sustainable, resilient, inclusive and competitive urban areas. Despite recent developments, there is still no consensus among researchers and practitioners regarding the concept of green infrastructure as well as its implementation approaches, which makes it often difficult for urban planners and other professionals in the field to develop a robust green infrastructure in some parts of the world. To address this issue, an integrative literature review was conducted to identify which green infrastructure planning principles should be acknowledged in spatial planning practices to promote sustainability and resilience. As a result of this literature review, the most common eight green infrastructure planning principles were selected—connectivity, multifunctionality, applicability, integration, diversity, multiscale, governance, and continuity. These principles intend to promote and simplify the development and use of green infrastructure by different academic and implementation organizations and provide a more defined model for sustainable landscape management in order to help practitioners and decision makers during the conceptualization and planning of green infrastructure.

Anthropogenic landforms are attractive landscape structures. They are linked to the cultural elements of the landscape and they also support biodiversity on the landscape level. Concerning their position within heritage concepts, anthropogenic landforms can be seen as a bridge between natural and cultural heritages. This paper is focused on the relevance of anthropogenic landforms to landscape management and planning. The study is based on the concept of geomorphosites, which can be applied within sustainable management and the conservation of geomorphological heritage. The case study was applied in the urban area of Brno (Czech Republic). The results of the study indicated the importance of anthropogenic landforms for urban landscape conservation and sustainable tourism development. The assessment of landforms in the study area enabled to establish a set of recommendations for the sustainable management of anthropogenic landforms in Brno. This study suggested the assessment of anthropogenic landforms as a support tool for sustainable landscape management in urban areas.

The Government of Rwanda sets up a conducive policy environment to invest in several development initiatives. Agriculture sector as the main contributor in the economic development received supports to sustainably manage Rwandan hilly landscape, dominantly ranging from 5 to 55% slope gradient. Intensive erosion control interventions confronted with different approaches have been introduced in the country such as participatory landscape management, (participatory) integrated watershed management and site-located intervention without any specified approach. This chapter intends to describe and evaluate the impacts of these previous approaches used in Rwanda in order to retrieve the success stories and encountered challenges as lessons learnt in the future interventions for optimizing land productivity in a sustainable manner. Participatory landscape approach in Gishwati area was a success story in protecting degraded lands and generating ecosystem benefits. It leads to more sustainable natural resources management from participatory planning up to implementation which addressed the frequent landslides, erosion and flooding while sustainably exploit the land to the profit of local farmers in the livelihoods. About 6,600 ha of lands have been successfully protected with full-packaged bench terraces, rangeland blocks and forest regeneration. This participatory approach also helped to relocate people from high risk zones to other safe places and build capacities of farmers through farm-livestock cooperatives. On the other side, Nyanza and Karongi sites under LWH project also emphasized strong evidences how land husbandry technologies (terraces) efficiently reduced erosion risks and improved farmers’ livelihoods. Lands were made productive with implementation of bench terraces on 3212 and 2673 hectares respectively for the two selected sites. However, challenges were observed from technical and socio-economic contexts which might have caused farmers to abandon or under-exploit the terraced lands. Finally, the chapter suggests to scale up the participatory landscape management approach which supports the involvement of farmers’ communities in the process.

The aim of this paper is to outline current foundations for sustainable landscape management in the Vilhelmina Model Forest, northwest Sweden. A case study revealed that the remaining patches of undisturbed or less disturbed boreal forest ecosystems comprise multiple values and, thus, constitute the basis for landscape planning. By identifying these patches, it is also possible to construct a spatial planning infrastructure for implementing sustainable management and land use. A more comprehensive toolbox needs to be developed, however, including monitoring and inventory schemes for relevant biophysical and socio-economic data, better temporal resolution for cause and effect analyses, and functioning scale-flexible planning and governance instruments.
