Nature conservation,countryside strategies and strategic planning

Countryside strategies, particularly for nature conservation, are part of a growth in non‐statutory strategic planning. They are largely integrative, and set the context for, and are able to cover subjects normally beyond the scope of, statutory development plans. Specifically for nature conservation, this paper summarizes the limitations of policies in structure plans and reviews four countryside strategies to assess the extent to which they overcome these limitations. Whilst providing a renewed focus for nature conservation, such strategies lack information and guidance in assisting plan formulation, are not accountable, have problems in their adoptability and lack the resources for implementation.     

Explaining the resource curse, with special reference to mineral-exporting countries

Recent studies have found an inverse correlation between economic growth and natural resource abundance among developing countries. There appears to be no obvious explanation for this finding, such as an important growth variable that is common in resource-poor countries and deficient in resource-abundant countries. The resource curse hypothesis is closely related to the problem of sustainability for resource-exporting countries since periods of high growth are frequently followed by long periods of stagnation. Models are examined showing how increases in export income can affect relative prices in the trade and nontrade sectors and how the changes in relative prices affect investment and growth. It is the thesis of this article that there is nothing inherent in resource-abundance that condemns countries to either low growth or nonsustainability.     

Nature conservation efforts set for specially protected areas of Turkey

Environmental pollution and degradation of ecosystems considerably affect the natural resources. The Turkish Government is aware of the importance of the preservation of natural ecology and thereby the environmental conservation of many species in their natural habitat. This paper provides critical assessments of the problems and possible solutions in the identification, implementation and management of the Specially Protected Areas (SPAs) system by giving basic information about stakeholders and their responsibilities that currently offer nature conservation in Turkey. The goals of the article are to analyze how the SPAs interface with the local people, especially the villagers who have dwelt there before SPA designation and how people-SPA conflicts resolved; to show how effective the SPA conservation objectives have been; to outline the significance of informing and empowering people in nature conservation for the protected area management and to show the importance of planning at all levels during protection of the natural, archeological and cultural values of the SPAs.     

Population viability analysis as a tool in wildlife conservation policy: With reference to Australia

Wildlife conservation policy for endangered species restoration follows a six-phase process. Population viability analysis (PVA) can play a major contributing role in four of these. PVA, as discussed here, is a technique where extinction vulnerabilities of small populations are estimated using computer simulation modeling. The benefits and limitations of using PVA in wildlife decision and policy processes are reviewed based on our direct experience. PVA permits decision makers to set time frames for management, estimate the required magnitude of restoration efforts, identify quantitative targets for species recovery, and select, implement, monitor, and evaluate management strategies. PVA is of greatest value for rare species policy and management. However, a limitation of PVA simulation models is that they are constrained by the amount of biological data available, and such data are difficult to obtain from small populations that are at immediate risk of extinction. These problems may be overcome with improved models and more data. Our experience shows benefits of PVA far outweigh its limitations, and applications of the approach are most useful when integrated with decision analysis and completed within an adaptive management philosophy. PVAs have been carried out for 14 Victorian species and less used elsewhere in Australia. Management and recovery plans are developed from these PVAs. We recommend that PVA be used to guide research programs, develop conservation strategies, and inform decision and policy making for both endangered and nonendangered species because it can significantly improve many aspects of natural resource policy and management.     

Mercury distribution in medium-size rivers and reservoirs of the Sao Paulo state (southeast Brazil)

The aim of this work was to investigate mercury (Hg) levels in six meso-scale watersheds (Upper Paranapanema, Aguapeí, Peixe, S?o José dos Dourados, Mogi-Gua?u, and Piracicaba) of the S?o Paulo state to contribute to a more comprehensive understanding of Hg contamination in Brazil. Water, sediment, bivalves, and fish samples were collected during 2001 at 11 sites. Fish were also collected in the Jurumirim and Salto Grande Reservoirs which are 39 and 52 yr old since impoundment, respectively. Results showed that Hg concentrations were low in almost all samples, except fish from Jurumirim Reservoir (total mercury [T-Hg] = 1.14 +/- 0.55 mg kg(-1) wet wt.). In spite of industrialization and high population, the results showed that there was no important source of Hg contamination in the investigated areas. The higher concentrations found in fish from Jurumirim seem to be the result of processes that favor Hg mobilization and methylation as a consequence of the impoundment of the reservoir area. The same levels were not observed in the Salto Grande Reservoir, probably because these are no longer significant due to the long time since the impoundment. To understand the dynamics of methylmercury (MeHg) production and its accumulation in fish, further studies are needed in the Jurumirim Reservoir. The results show that even at low T-Hg concentrations in sediment and water, concentrations in fish can reach values that pose concerns for consumption. This emphasizes the importance of designing an optimized biomonitoring program that can provide warning of biogeochemical conditions that promote formation of MeHg.

马来西亚对于我而言,是一个貌似熟悉,实际上却陌生的国度。熟悉的感觉来自于她与中国地理上的邻近。2008年暑假在新加坡实习的时候,我也曾造访过吉隆坡国际机场。想当然地以为大马和新加坡差别不大。2011年复活节假期,当我第一次踏足马来西亚,游历美丽的吉隆坡、马六甲和位于东马的沙捞越州,才惊叹于她魅力十足的热带风情、热情友善的多元族群以及良好的环境保护。     

Irrigation and collective action: A study in method with reference to the Shiwalik Hills, Haryana

In recent years decentralized development approaches have gained prominence in the agricultural sector. A host of community based watershed management projects have been implemented that encourage community organizations to undertake management of previously government controlled irrigation systems and forests. Community organizations have been given the responsibility of managing water distribution, collection of irrigation service fees and undertaking routine maintenance of irrigation infrastructure. In this context, analysis of irrigation management has concluded that groups that are relatively homogeneous may fare better than heterogeneous groups in facilitating collective action. However, this article argues that analysis of the influence of group heterogeneity on collective action is complicated because of its multi‐dimensional nature and the presence of non‐monotonic effects in mechanisms linking heterogeneity and collective outcomes. The article discusses the importance of context specification in analysis of group heterogeneity through a discussion of elements of a joint management contract in Haryana (India), identification of key variables with a potential to explain collective action in irrigation management and construction of household endowment and water interest scores to account for the influence of group heterogeneity in facilitating collective action. In the process of applying household endowment and water interest scores, the authors highlight the role of local ecological variation and non‐farm employment in influencing collective action. Proper specification of local context enables the researchers to rely on household endowment and water interest scores to predict conflicts and potential for irrigation service provision and compliance with irrigation service rules.

The contribution of environmental assessment by government,industry and others to the UK conservation strategy

Summary The author argues that sound, profitable and sustainable development should be pursued by all sections of the community: that there exist economic benefits to Governments in promoting sound ecological principles in development policies. He suggests that the environmental movement should be talking about development and environmental concerns as complementary issues, and believes that business enterprises should regard the limitation of environmental damage as simply one more facet of good business practice for good business reasons.Sir Arthur G. Norman, KBE, DFC, is the Chairman of The UK Centre for Economic and Environmental Development (CEED) and an interview with him was recently presented inThe Environmentalist 5 (3) 163–6. This paper was given as a closing address to a Conference entitledThe EEC Environmental Assessment Directive: Towards Implementation held at the Royal Society of Arts, London on 30th–31st January 1986. The Conference was organized by the Centre for Environmental Management and Planning, University of Aberdeen, assisted by the Department of the Environment (UK), the Confederation of British Industry, the Royal Town Planning Institute, the Landscape Institute and with the participation of the Commission of the European Communities.     

From agricultural intensification to conservation: sediment transport in the Raccoon River, Iowa, 1916-2009

Fluvial sediment is a ubiquitous pollutant that negatively affects surface water quality and municipal water supply treatment. As part of its routine water supply monitoring, the Des Moines Water Works (DMWW) has been measuring turbidity daily in the Raccoon River since 1916. For this study, we calibrated daily turbidity readings to modern total suspended solid (TSS) concentrations to develop an estimation of daily sediment concentrations in the river from 1916 to 2009. Our objectives were to evaluate long-term TSS patterns and trends, and relate these to changes in climate, land use, and agricultural practices that occurred during the 93-yr monitoring period. Results showed that while TSS concentrations and estimated sediment loads varied greatly from year to year, TSS concentrations were much greater in the early 20th century despite drier conditions and less discharge, and declined throughout the century. Against a backdrop of increasing discharge in the Raccoon River and widespread agricultural adaptations by farmers, sediment loads increased and peaked in the early 1970s, and then have slowly declined or remained steady throughout the 1980s to present. With annual sediment load concentrated during extreme events in the spring and early summer, continued sediment reductions in the Raccoon River watershed should be focused on conservation practices to reduce rainfall impacts and sediment mobilization. Overall, results from this study suggest that efforts to reduce sediment load from the watershed appear to be working.     

Framework for environmental impact analysis—with special reference to India

This article reviews the present status of environmental impact analysis (EIA) with special reference to India. In India, legislation already exists that makes EIA mandatory for every new project proposal. Critically analyzing the shortcomings of the present EIA practices, this article proposes a new framework to conduct an EIA, emphasizing that it should be part of the environmental management of the area or region. Among other things, we suggest the following important points: (1) that a comprehensive database of the region be developed for use for conducting an EIA; (2) that emission standards for the proposed industry be set and the existing standards for old industries be reviewed; (3) that a directory of experts be developed; and (4) that the Department of Environment should take responsibility for conducting EIA studies by forming a study team and an evaluation team for every EIA study with members drawn from the directory of experts.     

Pattern of representation of countries in cognitive maps of the world with special reference to Africa

Although for a long time environmental psychologists have been concerned with the nature and process of environmental perception and its representation in map forms, global sketch maps have not been popular in mainstream research. Further, conceptual and theoretical insights into the subject are yet to be fully achieved; and quite significantly, comparative analysis has been limited by the concentration of research efforts in the developed countries of Europe and America. In the same vein, the challenge of clarifying the psychological, spatial and social underpinnings of cognitive maps and their contributory role in day-to-day space-related problem solving and decision-making brings to the fore the need for cross-disciplinary and across-regional studies. This paper examines the world's image from an African perspective, exploring those countries of the world that are best known to Africans and the factors responsible for the pattern of recall and representation in the maps drawn by them. Some 656 maps were collected from 13 sites in 11 countries. Analysis of the frequency of inclusion of countries was first carried out; chi-square analysis was then performed on the frequency of inclusion by level of a country's economic development, population, geographical size and relative location from Nigeria and Africa. The results from qualitative interpretation show that while images of countries may have been influenced by composite and multifaceted factors, embracing historical and cultural associations, media images and invocations, Africans, nevertheless, tended to recall nations following some descending hierarchy, with ‘developed/geographically prominent countries’, ‘we’ (i.e. Africa), ‘others’ and ‘unknown’ countries as discernible clusters. From statistical test, population and spatial size of countries, the proximity of countries to the assessors and to some extent, level of economic development, were found to be significant in accounting for the pattern of recall and representation in cognitive maps. The paper shows that in spite of the evident limitations of mental sketches they hold some promise for our understanding of cross-regional variations in the images of the world, which could be important to the building of relevant social and geographical education to foster global understanding.     

Examination of the effects of disturbance on birds with reference to its importance in ecological assessments

National, European and International legislation regarding the conservation of species and habitats requires professional statements to be made in respect of land use change, as, for example, illustrated by developments. Some developments may cause disturbance to wildlife. Knowledge of the way in which species respond to disturbance has been fragmented, yet is an important consideration in environmental impact assessments. This paper reviews what is known about disturbance factors on the best studied group, birds. A set of extensive appendices summarize the literature on disturbance effects on breeding, breeding success, nest-site choice, population density, community structure, distribution and habitat use. The paper considers human-induced disturbance, public access, water-based recreation, shooting and industrial developments. Mitigation measures are discussed.Human-induced disturbance can have a significant negative effect on breeding success by causing nest abandonment and increased predation. Outside the breeding season, recreation (particularly power boating, sailing and coarse fishing on wetlands) reduces the use of sites by birds. Compensatory feeding at night by some species can probably recoup some of the energy losses caused by disturbance. Public and vehicular access to open landscapes has been shown negatively to affect grazing geese in winter and lowland and upland waders during breeding. Shooting disturbance has been shown to be most important for herbivore feeders which need to spend long periods of the day feeding in order to maintain their energy balance, e.g. wigeon. The provision of refuges devoid of shooting has been fundamental in attracting wildfowl away from non-refuge sites. The response of birds to scaring devices and other control measures is discussed.Effects from industrial developments include direct loss of habitat, disturbance through the presence of humans during the construction process and the presence of artificial light used to illuminate construction sites. On estuaries, engineering operations should avoid the proximity to established roost sites of wading birds. A number of studies showed increased vigilance (and hence reduced feeding time) in flock members feeding near structures which impede their vision of the approach of potential predators.A number of principal management techniques used to reduce disturbance on a site, or to attempt to compensate for habitat loss, are given. For wetland sites, these include excavating new shallow lagoons and grading bank sides, flooding of low-lying pasture, reducing salinity levels in coastal lagoons thereby making them more attractive to the birds' food invertebrates, manipulating water levels to expose mud regularly and creating feeding areas for geese and wigeon, using manipulative livestock grazing. Also used are increasing nesting cover, planting macrophytes, providing islands, spits and promontories, purchasing more land to make a refuge bigger, concealing observers with banks and screens, zoning activities and prohibiting access and avoiding the obstruction of flyways between feeding and roosting areas.     

Using social resilience and resource dependency to increase the effectiveness of marine conservation initiatives in Salum,Egypt

The social and economic ramifications of marine conservation strategies such as marine protected areas (MPAs) are important to consider prior to their implementation to ensure that they do not exceed the resilience of resource-users and that resource protection might be maximised through compliance and low resistance. This paper presents a framework in which the human dimensions can be more easily and usefully integrated into the design and delivery of conservation initiatives. The framework espouses quantifying (1) the level of dependency on the resource; (2) perceptions towards conservation initiatives; and (3) social resilience. The framework is applied in Salum, Egypt, which is the site of a prospective MPA.
