Many landscape and ecological features, such as riparian corridors, may span a number of different landholdings, and management practices are often inconsistent across those boundaries. Obtaining the co-operation of landowners thus emerges as one of the major obstacles to the attainment of Agri-Environmental Policy objectives, which are, to a greater or lesser degree, conditional on appropriate management practices being carried out at an appropriately extensive spatial scale. The utilization of the theoretical principles of landscape ecology is proposed as a framework for the planning and management of large areas, and a potential avenue whereby large-scale landscape plans could be matched with appropriate land-management frameworks. In spite of the difficulties associated with fragmented land ownership and land managers' differing perspectives and practices relating to conservation, the assumption that present patterns of farming and landholding are incompatible with the attainment of landscape-scale conservation management is challenged. The results of a study which has evaluated the scope for multiple-farm collaboration over conservation management planning, within the context of the uplands of the Lake District Environmentally Sensitive Area, are presented and discussed. Particular attention is drawn to the social dynamics of land ownership, neighbour relations and the 'problem' of common land as key issues in the sustainable management of upland landscapes.  相似文献

Agri-environmental schemes are often targeted at heterogenic landscapes to support several ecosystem services besides food production. The question is whether heterogenic landscapes also support recreation values. Previous studies suggest this but statistical analysis of the relation between heterogeneity and recreation is lacking. To assess this, we used a quantitative Landscape Heterogeneity Index (LHI), developed for biodiversity conservation. We asked five different user groups to score 12 photographs of landscapes depicting different LHI. All user groups, especially conservationists and hunters, preferred the heterogeneous landscapes and this difference was statistically significant for all groups except farmers. Accessibility, in terms of roads, had no obvious impact on the recreational value conveyed by the photos. The paper provides evidence that the recreational value amplifies biodiversity-based values of heterogeneous landscapes and argues that such landscapes also provide resilience and insurance value buffering against unexpected risks. Implications for policy are discussed.

Highlights ? Recreational value was positively correlated to landscape heterogeneity.

? This correlation was statistically significant for all user groups except farmers.

? Accessibility, in terms of roads, had no obvious impact on the recreational value.

? The multi-functionality of heterogeneous agricultural landscapes including resilience and the insurance value should be better acknowledged in policy.

Daodi Flood Land, located in Mentougou District of Beijing, is a relatively separate flood land in the lower reaches and on the east of Yonding River. This largest landscape character area in the west of Beijing along the river illustrates the history of human–water interaction and discloses the trends and problems of rural urbanization. Focusing on Daodi Flood Land, this paper expands the research on adaptation by introducing basic concepts and research framework, and reviews the research trends from spatial, temporal, and participant aspects. Considering the typical characters of the study area, this research employed participatory approaches, such as mapping and problem and solution trees, due to the lack of continuous and accurate data. Basing on literature review and field investigation on issues of floods, agricultural irrigation, and water resource utilization, water adaptive development visions for the study area were proposed from perspectives of landscape and culture. Finally, the paper further analyzes the structural relations between adaptation problems, natural and social systems, passive and active adaptations, and planned and unplanned adaptations, with the aim to provide reference for relevant studies and applications of adaptation approaches in other cases.  相似文献

The Sierra de Guadarrama is a valuable natural area, with ecological problems of degradation due to the high number of visitors from nearby Madrid. Visitors' landscape perception of the Sierra de Guadarrama is influenced by the activities they practise and, in the same way, their attitudes and expectations are not independent of the fact of practising one or another activity. Differences and conflicts between users are highlighted, and some recommendations for a better recreational use of the landscape are suggested.  相似文献

Extensive damage to the vegetation cover in arctic and alpine landscapes has raised the question of restoration as a possible management strategy. Restoration is a goal-oriented activity, a technological undertaking wider than its parent science of ecology. Social science and planning concepts and methods are necessary to handle the value judgements implicit in restoration. It is argued that the notion of 'desired state' is a better reference point in defining restoration goals than the notion of 'original state'. Using qualitative methods, two areas with vulnerable arctic/alpine vegetation are investigated. Based on participants' statements, four possible scenarios or desired states for future management are constructed. The main focus in the scenarios is on participants' attitudes to restoration activity, and it is shown how these are influenced by participants' attachment to the area and their view of nature.  相似文献

Phoslock® is a lanthanum (La) modified bentonite clay that is being increasingly used as a geo-engineering tool for the control of legacy phosphorus (P) release from lake bed sediments to overlying waters. This study investigates the potential for negative ecological impacts from elevated La concentrations associated with the use of Phoslock® across 16 case study lakes. Impact-recovery trajectories associated with total lanthanum (TLa) and filterable La (FLa) concentrations in surface and bottom waters were quantified over a period of up to 60 months following Phoslock® application. Both surface and bottom water TLa and FLa concentrations were <0.001 mg L−1 in all lakes prior to the application of Phoslock®. The effects of Phoslock® application were evident in the post-application maximum TLa and FLa concentrations reported for surface waters between 0.026 mg L−1–2.30 mg L−1 and 0.002 mg L−1 to 0.14 mg L−1, respectively. Results of generalised additive modelling indicated that recovery trajectories for TLa and FLa in surface and bottom waters in lakes were represented by 2nd order decay relationships, with time, and that recovery reached an end-point between 3 and 12 months post-application. Recovery in bottom water was slower (11–12 months) than surface waters (3–8 months), most probably as a result of variation in physicochemical conditions of the receiving waters and associated effects on product settling rates and processes relating to the disturbance of bed sediments. CHEAQS PRO modelling was also undertaken on 11 of the treated lakes in order to predict concentrations of La3+ ions and the potential for negative ecological impacts. This modelling indicated that the concentrations of La3+ ions will be very low (<0.0004 mg L−1) in lakes of moderately low to high alkalinity (>0.8 mEq L−1), but higher (up to 0.12 mg L−1) in lakes characterised by very low alkalinity. The effects of elevated La3+ concentrations following Phoslock® applications in lakes of very low alkalinity requires further evaluation. The implications for the use of Phoslock® in eutrophication management are discussed.  相似文献

The primary goal of this research was to explore the potential of farmer's knowledge as a source of information on the past and present cultural landscapes, focusing on the land-use system, the cultural heritage, and the farmer's perception of landscape changes, from the 1950s to the present day. For this purpose, 42 semi-structured interviews were conducted from a random sample of 10% of the villages in an area of the Northern Mountains of Galicia (NW Spain). As shown in farmers’ reports, the main crops in the 1950s were wheat or rye, potatoes or maize (only near the coast) and turnips. Scrubland areas were an essential resource for pasture, litter, temporary crops and charcoal, whereas deciduous forest was mainly used as a source of wood for carpentry, firewood and litter. Agriculture was the main economic activity, whereas crafts and other activities in the fisheries or forestry industry were secondary. Granaries, watermills and stone laundry basins were the most frequent elements of built heritage that was mentioned in the interviews. Farmers were also comprehensively aware of the broad changes that occurred in the landscape. The results indicate that farmer's knowledge is a valuable source of information for documenting past and present land-use practices, local cultural heritage and changes in the landscape, all of which are helpful for the design of landscape-orientated policies. Moreover, observed ancestral cultural practices, such as extensive grazing in scrubland areas, may be promoted as strategies for helping the sustainability of cultural landscapes in the study area and in other areas with similar characteristics.  相似文献

Business projects with an information technology component are referred to here as ‘business IT’ projects. Their success rate is found to be unsatisfactory, resulting in wasteful expenditure running to billions of dollars annually. Literature indicates that sound business cases, used effectively throughout the project lifetime, underpin governance and have a major positive impact on the project success rate. However, it also suggests that business case processes are seldom used properly.The goal of this study is to determine the extent to which business case processes are used in practice, and to understand the implications of the pattern that emerges.The data analysis from a survey reveals that business case usage diminishes significantly after approval is given to proceed, with potentially serious negative consequences. The findings offer initial building blocks for project business case theory; they also give valuable insights to management as to the required processes and how to avoid the prevailing pitfalls and achieve the intended strategic project benefits.  相似文献

Recognition and understanding of landscape dynamics as a historical legacy of disturbances are necessary for sustainable management of forest ecosystems. This study analyzed forest dynamics and spatial–temporal changes in land use/land cover pattern in a sub-temperate like alluvial forest land with 1778 km2 area along the Eagan Sea coast of Turkey (İnegöl). This area is studied by comparing Landsat images from 1987 to 2001 and evaluated with spatial analyses of forest cover type maps from 1972, 1983, 1993 to 2004 using GIS. The study investigated temporal changes of spatial structure of forest conditions over the period using Fragstats™.The results showed that the forested areas increased both in between 1972 and 1993 years (3.3%) and between 1987 and 2001 years (6.7%). In terms of spatial configuration, İnegöl forests are generally fragmented in the latter periods due to intensive forest utilization, illegal use, expansion of settlements and infrastructural development in the lowlands. Land use pattern significantly changed over time depending on a few factors such as unregulated management actions, social pressure and demographic movements. In conclusion, land use changes have developed in favor of forestry over time between 1972–1993 and 1987–2001. The study revealed that demographic movements have a minor effect on landscape dynamics. Both spatial and temporal changes and the factors affecting these changes should be determined for developing sustainable management of forest resources.  相似文献

The tension between the rural environment as the lived experience of those who dwell within it, and the objectification of that environment as scenery, is examined in the context of a change in planning legislation and philosophy. A discursive analysis of relevant documents demonstrates the application of a strong picturesque aesthetic. While the process of expert landscape assessment, as undertaken in this case study, immediately establishes a tension between outsider and insider, expert and inhabitant, the application of the picturesque aesthetic exacerbates it. In addition, the conflation of scenic quality with ecological health, which is an implicit feature of the picturesque aesthetic, results in a failure to adequately protect significant ecosystems as required under New Zealand's new planning law.  相似文献

The role of Area of Outstanding Natural Beauty (AONB) partnerships in the planning and management of landscapes is assessed. It is particularly explored how the AONB partnerships can provide focus for environmental planning through their strategies and the role they play in building consensus between different actors. The study is contextualized in light of recent findings from the Countryside Agency Review of AONBs, and the general move in environmental planning towards seeking integrated and sustainable solutions. A case study of the Wye Valley AONB is used in order to explore the types of collective ventures for landscape planning under the themes of landscape planning for visual amenity, planning for sustainable tourism and integrated rural land management.  相似文献
