Reconsidering Partisan Memorial Landscapes in un-brotherly and disunited times

Cultural landscapes are the product of innumerable changes wrought by generations in order to meet their aspirations, vanities, ambitions and weaknesses (Sudjic 2006: p.326). The inescapable nature of architecture makes it the ideal vehicle for those in power to manifest their authority, taste and will in the landscape by the buildings and monuments they construct and conserve and also the historical events and myths they commemorate and disseminate.
In the 1960s, many Yugoslav landscapes were altered by the construction of abstract Partisan spomenik (monuments) which dominated the skylines of former battle sites. This paper will discuss the how the collapse of Socialist ‘regime of memory’ and Yugoslavia has left these landscapes as legacies of a lost world of yesterday. It will consider how changing values are reflected by physical landscape changes and also by how and which critical events are commemorated.

Urban Ponds as an Aquatic Biodiversity Resource in Modified Landscapes

Urbanization is a global process contributing to the loss and fragmentation of natural habitats. Many studies have focused on the biological response of terrestrial taxa and habitats to urbanization. However, little is known regarding the consequences of urbanization on freshwater habitats, especially small lentic systems. In this study we examined aquatic macroinvertebrate diversity (family and species level) and variation in community composition between 240 urban and 782 non-urban ponds distributed across the UK. Contrary to predictions, urban ponds supported similar numbers of invertebrate species and families compared to non-urban ponds. Similar gamma diversity was found between the two groups at both family and species taxonomic levels. The biological communities of urban ponds were markedly different to those of non-urban ponds and the variability in urban pond community composition was greater than that in non-urban ponds, contrary to previous work showing homogenisation of communities in urban areas. Positive spatial autocorrelation was recorded for urban and non-urban ponds at 0-50 km (distance between pond study sites) and negative spatial autocorrelation was observed at 100-150 km, and was stronger in urban ponds in both cases. Ponds do not follow the same ecological patterns as terrestrial and lotic habitats (reduced taxonomic richness) in urban environments; in contrast they support high taxonomic richness and contribute significantly to regional faunal diversity. Individual cities are complex structural mosaics which evolve over long periods of time and are managed in diverse ways, promoting the development of a wide-range of environmental conditions and habitat niches in urban ponds which can promote greater heterogeneity between pond communities at larger scales. Ponds provide an opportunity for managers and environmental regulators to conserve and enhance freshwater biodiversity in urbanized landscapes whilst also facilitating key ecosystem services including storm water storage and water treatment.

Setting priorities for private land conservation in fire-prone landscapes: Are fire risk reduction and biodiversity conservation competing or compatible objectives?

Although wildfire plays an important role in maintaining biodiversity in many ecosystems, fire management to protect human assets is often carried out by different agencies than those tasked for conserving biodiversity. In fact, fire risk reduction and biodiversity conservation are often viewed as competing objectives. Here we explored the role of management through private land conservation and asked whether we could identify private land acquisition strategies that fulfill the mutual objectives of biodiversity conservation and fire risk reduction, or whether the maximization of one objective comes at a detriment to the other. Using a fixed budget and number of homes slated for development, we simulated 20 years of housing growth under alternative conservation selection strategies, and then projected the mean risk of fires destroying structures and the area and configuration of important habitat types in San Diego County, California, USA. We found clear differences in both fire risk projections and biodiversity impacts based on the way conservation lands are prioritized for selection, but these differences were split between two distinct groupings. If no conservation lands were purchased, or if purchases were prioritized based on cost or likelihood of development, both the projected fire risk and biodiversity impacts were much higher than if conservation lands were purchased in areas with high fire hazard or high species richness. Thus, conserving land focused on either of the two objectives resulted in nearly equivalent mutual benefits for both. These benefits not only resulted from preventing development in sensitive areas, but they were also due to the different housing patterns and arrangements that occurred as development was displaced from those areas. Although biodiversity conflicts may still arise using other fire management strategies, this study shows that mutual objectives can be attained through land-use planning in this region. These results likely generalize to any place where high species richness overlaps with hazardous wildland vegetation.

Creating restoration landscapes: partnerships in large-scale conservation in the UK

It is increasingly recognized that ecological restoration demands conservation action beyond the borders of existing protected areas. This requires the coordination of land uses and management over a larger area, usually with a range of partners, which presents novel institutional challenges for conservation planners. Interviews were undertaken with managers of a purposive sample of large-scale conservation areas in the UK. Interviews were open-ended and analyzed using standard qualitative methods. Results show a wide variety of organizations are involved in large-scale conservation projects, and that partnerships take time to create and demand resilience in the face of different organizational practices, staff turnover, and short-term funding. Successful partnerships with local communities depend on the establishment of trust and the availability of external funds to support conservation land uses. We conclude that there is no single institutional model for large-scale conservation: success depends on finding institutional strategies that secure long-term conservation outcomes, and ensure that conservation gains are not reversed when funding runs out, private owners change priorities, or land changes hands.

Constructing stability landscapes to identify alternative states in coupled social-ecological agent-based models

The resilience of a social-ecological system is measured by its ability to retain core functionality when subjected to perturbation. Resilience is contextually dependent on the state of system components, the complex interactions among these components, and the timing, location, and magnitude of perturbations. The stability landscape concept provides a useful framework for considering resilience within the specified context of a particular social-ecological system but has proven difficult to operationalize. This difficulty stems largely from the complex, multidimensional nature of the systems of interest and uncertainty in system response. Agent-based models are an effective methodology for understanding how cross-scale processes within and across social and ecological domains contribute to overall system resilience. We present the results of a stylized model of agricultural land use in a small watershed that is typical of the Midwestern United States. The spatially explicit model couples land use, biophysical models, and economic drivers with an agent-based model to explore the effects of perturbations and policy adaptations on system outcomes. By applying the coupled modeling approach within the resilience and stability landscape frameworks, we (1) estimate the sensitivity of the system to context-specific perturbations, (2) determine potential outcomes of those perturbations, (3) identify possible alternative states within state space, (4) evaluate the resilience of system states, and (5) characterize changes in system-scale resilience brought on by changes in individual land use decisions.

Forests as landscapes of social inequality: tropical forest cover and land distribution among shifting cultivators

Can social inequality be seen imprinted in a forest landscape? We studied the relationship between land holding, land use, and inequality in a peasant community in the Peruvian Amazon where farmers practice swidden-fallow cultivation. Longitudinal data on land holding, land use, and land cover were gathered through field-level surveys (n = 316) and household interviews (n = 51) in 1994/1995 and 2007. Forest cover change between 1965 and 2007 was documented through interpretation of air photos and satellite imagery. We introduce the concept of “land use inequality” to capture differences across households in the distribution of forest fallowing and orchard raising as key land uses that affect household welfare and the sustainability of swidden-fallow agriculture. We find that land holding, land use, and forest cover distribution are correlated and that the forest today reflects social inequality a decade prior. Although initially land-poor households may catch up in terms of land holdings, their use and land cover remain impoverished. Differential land use investment through time links social inequality and forest cover. Implications are discussed for the study of forests as landscapes of inequality, the relationship between social inequality and forest composition, and the forest-poverty nexus.

Reorganisation ofHoxdregulatory landscapes during the evolution of a snake-like body plan

Within land vertebrate species, snakes display extreme variations in their body plan, characterized by the absence of limbs and an elongated morphology. Such a particular interpretation of the basic vertebrate body architecture has often been associated with changes in the function or regulation of Hox genes. Here, we use an interspecies comparative approach to investigate different regulatory aspects at the snake HoxD locus. We report that, unlike in other vertebrates, snake mesoderm-specific enhancers are mostly located within the HoxD cluster itself rather than outside. In addition, despite both the absence of limbs and an altered Hoxd gene regulation in external genitalia, the limb-associated bimodal HoxD chromatin structure is maintained at the snake locus. Finally, we show that snake and mouse orthologous enhancer sequences can display distinct expression specificities. These results show that vertebrate morphological evolution likely involved extensive reorganisation at Hox loci, yet within a generally conserved regulatory framework.

‘Mo Rùn am Fearann’ – ‘My Love is the Land’: Gaelic landscapes of the 18th and 19th centuries

The period of the 18th and 19th centuries was one of great change in the Highlands and Islands of Scotland. Improvement, the Jacobite Rebellions, and the Clearances transformed its communities and landscapes. These events have rightly been a focus of research. However, archaeological approaches have often sought simply to illustrate these processes, rather than create new narratives about life in the past. The resulting picture of the period can over-emphasise economic change whilst failing to reflect the richness and variety of everyday life. This thesis aims to suggest a new approach to the place and period, one which addresses matters often ignored in previous work. Whilst it has an archaeological sensibility, it draws on ideas from outside archaeology, such as landscape theory and on Gaelic oral tradition, an underused resource, to create a novel and broad-based approach to the period. An important part of the method is a synchronic approach that seeks to reconstruct the experience of the landscape at very particular times, engaging fully with the everyday experience of landscape rather than grand historical narratives. Two Hebridean case studies are utilised: Hiort (St Kilda) and Loch Aoineart, South Uist. Thematic discussions drawn from these landscapes are intended as critical assessments of the efficacy of the approach, as well as new narratives about life in the past in themselves. The thesis concludes by comparing the two case studies, reflecting on the merits of the approach, discussing recurrent themes in the work, and considering its wider context and implications. It is concluded that taking a novel approach to the case study landscapes can create narratives that often contrast or expand upon those produced by previous scholars, allow for a more detailed consideration of everyday life in the period, and open up new areas for archaeological enquiry. The extensive and critical use of evidence from Gaelic oral tradition is highlighted as crucial in understanding life and society in the period. The thesis questions the utility of grand historical narratives as a framework for archaeological study of post-medieval Gaeldom and suggests that our understanding of the past is best served by approaching the evidence in ways which allows for many different voices and stories from the past to emerge.

A GEOBIA methodology for fragmented agricultural landscapes

Very high resolution remotely sensed images are an important tool for monitoring fragmented agricultural landscapes, which allows farmers and policy makers to make better decisions regarding management practices. An object-based methodology is proposed for automatic generation of thematic maps of the available classes in the scene, which combines edge-based and superpixel processing for small agricultural parcels. The methodology employs superpixels instead of pixels as minimal processing units, and provides a link between them and meaningful objects (obtained by the edge-based method) in order to facilitate the analysis of parcels. Performance analysis on a scene dominated by agricultural small parcels indicates that the combination of both superpixel and edge-based methods achieves a classification accuracy slightly better than when those methods are performed separately and comparable to the accuracy of traditional object-based analysis, with automatic approach.

Self determination, embodied languages and landscapes in women's video art.

This paper addresses how, since the 1960s to the present, part of women's video art has broken the traditional representation of women’s body and proposed new forms of recording women's images, explicit or symbolic, using body part close-ups, and not sparing any efforts to ensure the prevention of the cataloguing of women’s bodies according to normative categories, such as gender, race and age, and in this way challenging the Western representation codes that objectify women. The methodology employed had as its primary purpose the examination of the association existing between the micro-sociological level of body gestures and performances in women's videos and the macro-sociological level of social forces such as the dimensions of gender and sexuality. This study concluded that narratives of identity and self-determination are present in women's video pieces contributing to women's empowerment through visual discourses that could possibly point to the production of new signs and symbols, new values and models, but also for the formation of new types of social roles and even a new type of interpersonal relationships.
