Measures of safeguard and rehabilitation for landscape protection planning: a qualitative approach based on diversity indicators

Visibility Analysis to Enhance Landscape Protection: A Proposal of Planning Norms and Regulations for Slovakia

The visibility of a landscape is an important aspect of landscape protection planning because different rules or norms can be defined to regulate land-use and human activities depending on the degree of landscape visibility. Viewshed analyses are common GIS-based approaches to evaluate which parts of the landscape can be seen from certain points or by people located or moving in the landscape. In this work, the visibility of the entire landscape of the Slovak Republic is assessed from the network of major national roads. The results of the landscape visibility analysis are then used to propose appropriate planning norms and regulations to protect the identified visibility values and avoid potential visual obstructions from new buildings or infrastructure development. Particularly, the proposed norms indicate allowable changes to the landscape and the maximum height of new or existing buildings and other urban infrastructure. Maps of the spatial distribution of the proposed norms identify possible situations of consistency or conflict with potential urban development trends, to support landscape protection planning processes at the national level. On average, the most visible land-use/land-cover categories are glacial mountains relief, plane depressions, and wide alluvial plains, while the planning indications/prescriptions to protect landscape visibility have been proposed for irrigated land and forests. Thanks to the limited use of geographic datasets, the method ensures high transferability to other different geographic contexts, and allows to derive planning indications for large national contexts.

Nature as a facilitator for physical activity: Defining relationships between the objective and perceived environment and physical activity among community-dwelling older people

The aim was to study the correspondence between the objective and perceived environment and to assess their associations with physical activity (PA) in older people. 848 community-dwelling older people aged 75-90 were interviewed on their difficulties in walking 500m, perceiving nature as a facilitator for outdoor mobility, and PA. The presence of water and landscape diversity were objectively assessed inside 500m and 1000m circular buffers around participants' homes. Using logistic regression, participant data were analyzed together with the objectively assessed environmental features. Our results indicate that higher habitat diversity within natural areas correlates with higher PA among older people without walking difficulties and the presence of water correlates with higher PA among those with walking difficulties.

Geomorphology applied to landscape analysis for planning and management of natural spaces. Case study: Las Batuecas-S. de Francia and Quilamas natural parks, (Salamanca, Spain)

Geomorphology is fundamental to landscape analysis, as it represents the main parameter that determines the land spatial configuration and facilitates reliefs classification. The goal of this article is the elaboration of thematic maps that enable the determination of different landscape units and elaboration of quality and vulnerability synthetic maps for landscape fragility assessment prior to planning human activities. For two natural spaces, the final synthetic maps were created with direct (visual-perceptual features) and indirect (cartographic models and 3D simulations) methods from thematic maps with GIS technique. This enabled the creation of intrinsic and extrinsic landscape quality maps showing sectors needing most preservation, as well as intrinsic and extrinsic landscape fragility maps (environment response capacity or vulnerability towards human actions). The resulting map shows absorption capacity for areas of maximum and/or minimum human intervention. Sectors of high absorption capacity (minimum need for preservation) are found where the incidence of human intervention is minimum: escarpment bottoms, fitted rivers, sinuous high lands with thick vegetation coverage and valley interiors, or those areas with high landscape quality, low fragility and high absorption capacity, whose average values are found across lower hillsides of some valleys, and sectors with low absorption capacity (areas needing most preservation) found mainly in the inner parts of natural spaces: peaks and upper hillsides, synclines flanks and scattered areas. For the integral analysis of landscape, a mapping methodology has been set. It comprises a valid criterion for rational and sustainable planning, management and protection of natural spaces.

Integrated land use and regional resource management--a cross-disciplinary dialogue on future perspectives for a sustainable development of regional resources

Our paper introduces objectives and ideas of the special issue "Integrated land use and regional resource management - A cross-disciplinary dialogue on future perspectives for a sustainable development of regional resources" and provides an overview on the contributions of the single papers in the special issue to this topic. Furthermore, we discuss and present major challenges and demands on integrated land use and regional resource management and we come up with an analytical framework how to correspond these demands.
