Abstract The majority of forest cover in the British Uplands had been lost by the beginning of the Nineteenth Century, because of felling followed by overgrazing by sheep and deer. The situation remained unchanged until a government policy of afforestation, mainly by exotic conifers, after the First World War up to the present day. This paper analyses the distribution of these predominantly coniferous plantations, and shows how they occupy specific parts of upland landscapes in different zones throughout Britain Whilst some landscapes are dominated by these new forests, elsewhere the blocks of trees are more localised. Although these forests virtually eliminate native ground vegetation, except in rides and unplanted land, the major negative impacts are at the landscape level. For example, drainage systems are altered and ancient cultural landscape patterns are destroyed. These impacts are summarised and possible ways of amelioration are discussed. By contrast, in recent years, a series of projects have been set up to restore native forest cover, as opposed to the extensive plantations of exotic species. Accordingly, the paper then provides three examples of such initiatives designed to restore native forests to otherwise bare landscapes, as well as setting them into a policy context. Whilst such projects cover a limited proportion of the British Uplands they nevertheless restore forest to landscapes at a local level.

The aim of the study is to develop a project for the rational organization of the use of agricultural land for land use on the basis of a comprehensive integrated assessment and landscape-ecological analysis, involving their landscape-ecological optimization, conservation of landscape diversity. This project will establish the main criteria for the optimization of agricultural lands as natural-economic systems: land and resource security; level of forest cover; agricultural load on landscapes (erosion level, specific gravity of irrigated and drained lands, livestock load per 100 ha of fodder land); the degree of agrogenic load on agrolandscapes (specific gravity of steam, indicators of plowing and agricultural development); landscape-ecological conditions (landscape situation, drainage of landscapes, relief, soil; water and radiation balances; manifestation of adverse physical and geographical processes); spatial and technological conditions (a variety of landscape patterns of arable land and other lands, their configuration and size); the degree of environmental tension (the degree of development of natural physical and geographical processes and anthropogenic ones: salinization, waterlogging, flooding, pollution of soils, snow, air and water basins, etc.); the amount of agricultural losses; environmental, social and economic efficiency of the implementation of design developments. The methods used are: abstract-logical, integrated landscape and environmental assessment, cartographic, modeling methods.

Abstract ContextThe vital challenge for the context-based landscape planning is integrating assessments of for both intrinsic properties of a unit and its value in a broad spatial context.ObjectivesThe purpose is to develop the procedure which provides context-based criteria at relevant scales, considers matter flows and dynamic events.MethodsThe methodology involves identification of landscape patterns, revealing mechanisms of radial and lateral relationships, considering changes of landscape patterns, and revealing functioning mechanisms causing directed changes. The proposals proceed from multiplicity of patterns and integrate knowledge of processes in biophysical units, catenas, basins, and matrix elements. The plan was elaborated for the taiga landscape in northern European Russia.ResultsDevelopment of ecological network is aimed at increase of forest cover in basins up to 35% to enhance runoff regulation, prevent soil erosion, and stabilize the riparian biocorridor. The highest significance was assigned to the units that have intrinsic ecological values and contribute to lateral transportation of matter over vast areas. Width of buffer strips intercepting input of pollutants to rivers was adapted to proportions of elements and neighborhoods in catenas. Outside the ecological network, we identified priorities for the multifunctional use of units based on the assessment of drainage conditions, soil quality, and risk of erosion. ConclusionsThe procedure takes into consideration landscape hierarchy and multiplicity of spatial patterns. Integrating multiple models is in compliance with the systemic essence of a landscape ensuring understanding of geodiversity, lateral connections, and the emergent effects that ensure the landscape services for society.

Megachile sculpturalis (Smith, 1853) is the first exotic bee species in Europe. Its remarkably fast expansion across this continent is leading to a growing concern on the extent of negative impacts to the native fauna. To evaluate the interactions of exotic bees with local wild bees, we set up trap nests for above-ground nesting bees on a semi-urban area of north-western Italy. We aimed to investigate the interaction in artificial traps between the exotic and native wild bees and to assess offspring traits accounting for exotic bee fitness: progeny sex ratio and incidence of natural enemies. We found that the tunnels occupied by exotic bees were already cohabited by O. cornuta, and thus the cells of later nesting alien bees may block the native bee emergence for the next year. The progeny sex ratio of M. sculpturalis was strongly unbalanced toward males, indicating a temporary adverse population trend in the local invaded area. In addition, we documented the presence of three native natural enemies affecting the brood of the exotic bee. Our results bring out new insights on how the M. sculpturalis indirectly competes with native species and on its performance in new locations.

Abstract. Uncertainty in rainfall datasets and landslide inventories is known to have negative impacts on the assessment of landslide–triggering thresholds. In this paper, we perform a quantitative analysis of the impacts that the uncertain knowledge of landslide initiation instants have on the assessment of landslide intensity–duration early warning thresholds. The analysis is based on an ideal synthetic database of rainfall and landslide data, generated by coupling a stochastic rainfall generator and a physically based hydrological and slope stability model. This dataset is then perturbed according to hypothetical reporting scenarios, that allow to simulate possible errors in landslide triggering instants, as derived from historical archives. The impact of these errors is analysed by combining different criteria to single-out rainfall events from a continuous series and different temporal aggregations of rainfall (hourly and daily). The analysis shows that the impacts of the above uncertainty sources can be significant. Errors influence thresholds in a way that they are generally underestimated. Potentially, the amount of the underestimation can be enough to induce an excessive number of false positives, hence limiting possible landslide mitigation benefits. Moreover, the uncertain knowledge of triggering rainfall, limits the possibility to set up links between thresholds and physio-geographical factors.

Recession is considered as a major threat to the economy as it slows down economic activities. The property development sector is extremely responsive to these economic conditions. Thus, it is crucial to understand causes, effects and strategies for property developers to survive in a recession without any ill effects. Thus, this research aimed to develop a framework for property developers to identify appropriate survival strategies in recession. A comprehensive literature review was conducted in this research to achieve the above mentioned aim. The results of this study indicated that recession prompts negative impacts on property development sector resulting in unemployment, lower demand, production and revenue, decline in resources and high level of competition. According to the results, the survival strategies were classified into short-term and long-term strategies. The short term strategies include: implementing management tactics, cut down of operating costs, keeping financing lines set up, timely repayment of debts, setting vital new objectives for the future, undertaking shorter time span developments, specialisation in favoured market, renegotiating deals and contracts. The long-term strategies include retrenchment, restructuring, investment and ambidextrous strategies. Similarly, attention should be paid to predict any changes in the economic environment that can influence property development activities and it is necessary to carefully evaluate investment activities to increase sales, profits and market shares of property developers. Preparing for a crisis is doubtlessly the ideal approach as it can facilitate both survival and growth. Thus, the property developers can implement these suggested strategies in their businesses to enhance their practices.

The suspended pitfall demonstrates a new and simple mechanism to capture small arboreal and scansorial mammals. It is an arboreal version of the pitfalls traditionally used to capture terrestrial amphibians and reptiles. Buckets with bait inside are raised by a rope until they reach a tree branch at the desired height. Tests were performed in the Atlantic Forest at three different sites at the mouth of Doce River in Linhares, southeastern Brazil. In one of them suspended pitfalls were set up in the understory of a shaded cacao plantation (cabruca agroforest) in the branches of cacao trees between 2 and 3 m in height, and in the other they were placed in a native forest between 5 to 15 m in height. At the third site, suspended pitfalls were tested together with the other live traps used hitherto in the understory of other cabruca agroforest. The marsupials Didelphis aurita, Caluromys philander, Marmosa (Micoureus) paraguayana, Gracilinanus microtarsus, Marmosa murina and the rodent Rhipidomys mastacalis were captured by suspended pitfall. This live trap was capable of catching all sizes of small arboreal mammals, including juvenile individuals. This method proved to be functional for the capture of some small arboreal mammals and may be a complementary alternative for sampling in high forest strata.

Dybbøl is the brow of a hill located about 30 km north-east of the border between Denmark and Germany. This area was once the former Danish Duchy of Schleswig, which was under German rule in the period from 1864 to 1920. Dybbøl was also the site of intense fighting during the Schleswig-Holstein Revolt of 1848–50 and the Danish-German War of 1864. There are remains of both Danish and German fortifications and earthworks, along with large mass graves in which troops from Denmark, Schleswig-Holstein and Germany lie buried. After a plebiscite about the placing of the border was held in 1920, Schleswig was divided up, and the northern part – which included Dybbøl – became part of Denmark. This was followed by a comprehensive ”Danishification” of the cultural landscape, which had previously been dominated by a large Prussian victory monument and numerous German memorial stones. A Danish national park was set up at Dybbøl in 1924, with the backing of the local population and financial sup- port from a national collection appeal, and formally opened by the Danish prime minister. After this, Dybbøl became the epitome of the institutionalised cultural heritage of the state of Denmark, and would almost certainly be included in any ”cultural canon” of the most significant geographical locations that have helped shape the Danish sense of national identity. However, Dybbøl also features another – less comfortable – aspect of the Danish cultural heritage, bearing witness to Danish acts of vandalism perpetrated against the German monuments found here. Any study of the use of the history associated with Dybbøl uncovers layer upon layer of episodes that speak of conflicting interests and countless metamorphoses that led to the site being imbued with new values and a sequence of new identities. And in step with the resurgence of nationalist sentiments in Denmark since the mid-1980s, there has been a corresponding, strengthened re-annexation of the cultural heritage associated with Dybbøl. The need to cling on to and retain establis- hed, familiar positions and a fundamental sense of belonging are well-known aspects of the process of globalisation, and are seen throughout the world. In Dybbøl, this deep-felt need has resulted in the construction of a Danish fortification, and the Danish flag flying atop the many flagpoles has become more frequent sight. This process can also be interpreted as an expression of Danish foreign policy taking on a more active role in the world.

Pakistan is exposed to various natural calamities due to its geophysical condition and climatic changes. In addition, man-made disasters also pose a threat to human lives and properties which includes industrial and transport disasters including oil spills, civil unrest, wars and conflicts. Although it is not possible to stop or prevent natural disasters, but the negative impacts of natural disasters can be minimized through human efforts. The government of Pakistan has adopted participatory approach as part of its policy for disaster management. This research paper is based on the analysis of secondary data for reviewing the existing policies with emphasis on disaster risk reduction in pre and post disaster period. The paper concludes that participation of target community is indispensable for disaster risk reduction on sustainable basis. The article suggests that community should be meaningfully involved in disaster risk reduction efforts at the local level. In this connection the role of social workers is indispensable for disaster risk reduction on sustainable basis.

Purpose – Discussing the Swiss case, the purpose of this paper is to examine how gender equality policies deal with the present requirements for scholars to be considered “excellent”. It aims to pinpoint the lines of tension or coherence between excellence, meritocracy and gender politics. Design/methodology/approach – In order to specify the norms of academic careers and their different renditions, the author draws on two studies (at local and national levels) to illustrate where the changes and resistances are taking place. Findings – The translations of a number of demands of feminist movements into the policies set up to favour equality between the sexes may combine to challenge the norms of academia as a gendered realm. Nevertheless, without strong pressure from feminists at local level and the conduct of research pursuing the enterprise of deconstructing norms, top-down policies may prove less “corrective” than affirmative action. This pressure is not only useful to build gender equality in science but also to broaden the spectrum of knowledge that can become a common good. Research limitations/implications – As neither the names nor the positions of the experts who select the candidates at national level are made public, we had to opt for other, less satisfactory means. Originality/value – The originality of the paper lies in the link made between the enhancements brought by Equalities policies and the changes they bring. It attempts to bring to light the extent to which gender equality policies conform to the neo-managerial order or challenge its norms to build a world that is more just.

Purpose Governance of e-government is rarely discussed in the initial digitization stage, especially in developing countries where the government’s focus is mainly to pursue rapid proliferation of digital adoption rather than to implement governance. This study aims to explore the consequences of this absence of governance at local level conditions. Design/methodology/approach An in-depth exploratory case study is conducted at a municipal health government in a southern city in Kalimantan Island, Indonesia, examining the conditions of local actors in response to various nationwide health digitization imperatives. The postcolonial theory with the critical paradigm is used to interpret and conceptualize the empirical findings. Findings This study identifies two critical failures of digitization governance that represent the mainstream condition: horizontal sectoral ego and vertical asymmetry and misalignment. These failures have resulted in undesirable consequences at the subalterns indicated by diverse ambivalence and de-voiced constructs displayed by the local actors. Practical implications This paper suggests that various issues that emerge from local level implementation in nationwide digitization agenda might not always be issues of local technology adoption, but rather negative impacts due to the absence of governance practice at the strategic level. Originality/value Through a critical perspective, this study unearths the underlying power and structural inequity responsible for generating the various issues and undesirable consequences that emerge at local levels related to the nationwide digitization agenda.
