In Slovenia, mass movements are not only a threat to the population, but also a major environmental and social science challenge. Lithologically heterogeneous areas have been found to be problematic, and the Miocene Slovenj Gradec basin (in northeast Slovenia) is one such area. For this area, we developed landslide and rockfall susceptibility maps based on detailed geological research combined with statistical modeling schemes. Crucial factors include lithological composition, land use, geological structural elements, slope curvature, aspect and inclination, and bed dipping. The approach taken in the development of mass movement susceptibility maps presented here is transferable to other areas defined by heterogeneous lithology. Such maps could prove useful spatial planning, forestry, environmental protection, landscape architecture, and other fields.

Abstract. Recent developments in land consumption assessment identify the need to implement integrated evaluative approaches, with particular attention to the identification of multidimensional tools for guiding and managing sustainable land use. Policy decisions defining land use are mostly implemented through spatial planning and related zoning, and this involves trade-offs between many sectoral interests and conflicting challenges aimed at win-win solutions. In order to identify a decision-making process for land use allocation, the paper proposes a methodological approach for a Dynamic Spatial Decision Support System (DSDSS), named Integrated Spatial Assessment (ISA), supported by Geographical Information Systems (GIS) combined with Analytic Hierarchy Process (AHP). Through the empirical investigation in an operative case study, an integrated evaluative approach implemented in a DSDSS helps to elaborate "urbanization susceptibility maps", where spatial analysis combined with a multi-criteria method proved to be useful for facing the main issues related to land consumption and minimizing environmental impacts of spatial planning.

Our spatial environment is one of the most important determinants of our well-being and life chances. It relates to schools, opportunities, businesses, recreation and access to public services. Spatial injustice results where discrimination determines that spatial environment. Since Apartheid in South Africa epitomised the notion of spatial injustice, tools and instruments are required to transform spatial injustice into spatial justice. One of these is the employment of principles of spatial justice. While the National Development Plan (NDP) recognised that all spatial development should conform to certain normative principles and should explicitly indicate how the requirements of these should be met, the Spatial Planning and Land Use Management Act 16 of 2013 (SPLUMA) contains a more concrete principle of spatial justice. It echoes aspects of both the South African land reform programme and global principles of spatial justice. Essentially section 7(a) of SPLUMA entails three components: (1) redressing past spatial imbalances and exclusions; (2) including people and areas previously excluded and (3) upgrading informal areas and settlements. SPLUMA directs municipalities to apply the principle in its spatial development frameworks, land use schemes and, most importantly, in decision-making on development applications. The aim of this article is to determine whether the application of this principle in practice can move beyond the confines of spatial planning and land use management to address the housing issue in South Africa. Central to housing is section 26 of the Constitution, that has received the extensive attention of the Constitutional Court. The court has not hesitated to criticize the continuing existence of spatial injustice, thus contributing to the transformation of spatial injustice to spatial justice. Since planning, housing and land reform are all intertwined not only the role of SPLUMA, but also the NDP and the myriad other policies, programmes and legislation that are attempting to address the situation are examined and tested against the components of the principle of spatial justice in SPLUMA.

Changes in land-use can have an important effect on rates of erosion and denudation. In order to avoid accelerating erosion rates, decision makers in land-use planning require adequate information on the contemporary geomorphological processes and hydrology of areas where modifications in the land-use pattern are envisaged. The first phase in the acquisition of the information is the reconnaissance survey, which shows where and how the erosional status of an area is likely to be affected, and also acts as a foundation on which to base more detailed work in the future.The Solitude area is an active erosional system, dominated by mass movement and fluvial processes. The rate of removal of material is likely to be increased by modifications in land-use which, from other points of view, would be considered entirely suitable for the area. Therefore, if accelerated denudation is to be avoided, projects involving land-use changes should be implemented only by those having an adequate understanding of the mechanism of geomorphological processes operating in the area.

Abstract Protected areas can be parts of larger ecosystems, and land use changes in the unprotected part of the ecosystems may threaten the biological diversity by affecting the ecological processes. The relationship between protected areas and their surroundings has been influential in understanding the role of spatial planning in nature conservation. This article focuses on the problem that Turkey’s protected areas are vulnerable to pressure and threats caused by land use changes. Spatial planning serving as a bridge between nature conservation and land use is the solution for effective nature conservation in Turkey. Thereby, the aim of this article is to develop a conceptual framework which offers spatial planning as an effective tool to bridge the gap between land use change and nature conservation. In this context, first literature review is conducted, and systematic conservation planning, evidence-based conservation planning, bioregional planning and national system planning are presented as effective planning methods in nature conservation. In addition to literature review, official national statistics and Convention on Biological Diversity’s country reports are utilized to shed light on Turkey’s current state. Finally, a conceptual framework is defined, the main differences with the current situation are revealed. The results indicate that an effective planning system for Turkey’s protected areas incorporates a holistic, target-oriented system defining the spatial planning process for protected areas. The spatial planning system to be developed in this context is also used by decision-makers in evaluating the ecological effectiveness of existing plans.

ABSTRACTInsect migrations rival those of vertebrates in terms of numbers of migrating individuals and even biomass, although instances of the former are comparatively poorly documented. This is especially true in the world’s tropics, which harbor the vast majority of Earth’s insect species. Understanding these mass movements is of critical and increasing importance as global climate and land use change accelerate and interact to alter the environmental cues that underlie migration, particularly in the tropics. Here, we provide the first evidence for an insect migration for the nymphalid butterfly Panacea prola in the Amazon, the world’s largest and most biodiverse rainforest that is experiencing a shifting climate and rapid forest loss.
