Current Practices in Monitoring and Reporting on Sustainability of Visitor Use of Protected Areas
No full textMany protected areas, especially national parks, have a dual function of preserving valued resources and realising the recreational values inherent within the area. The outcome of this duality can be difficult for protected area managers to reconcile when satisfying visitor use experiences threatens other values, especially biodiversity values. Understanding visitor use and its effect on biophysical resources is an important part of effective management. Monitoring of use and its effects, therefore, becomes vital to an adaptive management approach to address this sometimes conflicting management duality. Of concern though is the development and use of indicators to report on the sustainability of visitor use and management in protected areas (McCool & Stankey 2004).
While protected area managing agencies in Australia have long been concerned with monitoring visitor impacts and experiences, the efforts have largely been site and activity specific, with no consistent methodological approach to enable confident application beyond the site and issue of the specific monitoring. This project sought to describe current approaches to the monitoring and evaluation of visitor use of protected areas and make recommendations regarding an integrated approach

Valuing an ecotourism resource : a case study of the Boulders Beach African penguin colony
No full textThe colony of African Penguins at Boulders, Simon's Town on the southern Cape Peninsula, Western Cape formed in 1985, and is now a major ecotourism destination. The African Penguin is listed as Endangered due in part to competition with commercial fisheries. Improvements in the spatial management of these fisheries could assist with the conservation of the penguins, but would be costly. Various techniques were used to estimate the value of the colony, and to assess its impact on the economy of the southern Peninsula

Identification and regionalization of dominant runoff processes – a GIS-based and a statistical approach
No full textIn this study two approaches are presented to identify Dominant Runoff Processes (DRP) with respect to regionalization. The approaches are a simplification of an existing method to determine DRP by means of an extensive field campaign. The first approach combines the permeability of the substratum, land-use and slope of the basin in a GIS-based analysis. The second approach makes use of discriminant analysis of the physiographic characteristics of the basin and links it to the GIS analysis. The results of the developed approaches are maps, which identify dominant runoff processes and represent a spatial distribution of the hydrological behaviour of the soil during prolonged rainfall events. The approaches have been developed in a micro-scale basin (Germany). An additional meso-scale basin was introduced in which the two approaches were applied for quality control. The thus generated maps for the micro-scale basin were compared with an existing DRP map, which was derived with the existing method. The first approach showed a resemblance of 79% when compared to this map, whereas the second approach showed only a resemblance of 51%. The generated maps for the meso-scale basin were compared to DRP that were determined point wise according to the existing method. The first approach showed in this case a resemblance of 81%, whereas the second approach showed a resemblance of 68%. Therefore, the first approach is preferred to the second approach when accuracy, data input and calculation time are concerned.WatermanagementCivil Engineering and Geoscience
Polymer-based treatments to control runoff, leachate and erosion from engineered slopes at Simfer Mine, Guinea, Africa
No full textIt is necessary to understand the erodibility and hydrological response of mine-site slope forming materials (SFMs), because of increasing awareness of the environmental impacts of mining. Steep engineered slopes in high intensity rainfall environments present a serious erosion risk. Temporary surface stabilisers, such as polyacrylamides (PAMs) and polyvinylacrylic latex (PVALs) are potentially cost effective erosion control solutions. In this study PAM and PVAL efficacy to reduce runoff, leachate and erosion was assessed at two application rates, with and without gypsum on SFMs from an iron ore mine in Guinea (West Africa). NSPASS (near-surface photogrammetry assessment of slope forming materials’ surface roughness) is a novel method that integrates digital image capture and GIS. It is shown to detect and quantify surface micro-relief changes of 2-3 mm, not visible to the naked eye.
As expected, soil and non-soil SFMs were significantly different in terms of their physical and chemical properties. Phase I of the study investigated the erodibility of ten SFMs, including soil, ore and waste-rock. The results indicate that the hydrological response to rainfall of most SFMs is to generate leachate. Weathered phyllite (PHY-WEA) is the most erodible SFM by both runoff and leachate. Multiple regression analysis demonstrated that magnetic susceptibility, mineralogy and dry aggregate distribution; parameters not commonly assessed in erosion studies, are important in explaining SFM erodibility and hydrological response.
Phase II evaluated critically the effectiveness of three commercially available polymer solutions (two PAMs and one PVAL) at reducing runoff, leachate and erosion from four of the most erodible SFMs identified in Phase I. The results indicate that some PAM and PVAL treatments significantly reduce runoff, leachate and erosion. Polymer efficacy is highly dependent on the physical and chemical properties of the SFM, as well as the mechanism of polymer to SFM adsorption. Increasing the application rate of select treatments lowered leachate volumes, runoff and leachate total sediment loads. Contrary to previous studies, gypsum amendments did not significantly improve polymer efficiency.
This research has added to our understanding of the erodibility and hydrological response of soil and non-soil SFMs. This is the first study to evaluate critically the efficacy of PVALs in controlling erosion from mine-site SFMs. Future studies should continue to optimise NSPASS performance in monitoring changes in surface micro-relief
Measuring integrated rural tourism.
No full textIf the concept of integrated rural tourism, as developed in the SPRITE project, is to be used as an operational tool to assess the all-round value of tourism in rural areas, there needs to be a means of measuring the value of tourism, and changes in it. Statistical, 'objective' methods of achieving this are critiqued. This paper describes the development of an alternative methodology for assessing the changes in the value of tourism witnessed by different groups of stakeholders in the study areas across Europe between 1992 and 2002. The methodology allows for a holistic view of the extent to which rural tourism is integrated into the local economies and cultures. Differences in perceptions regarding change in the value of tourism between actor groups and countries are noted. Illustrative examples are given of specific events and forms of rural tourism that are perceived as being of high value. It is concluded that while tourism is now better integrated than it was ten years ago, further improvements can be made in identifiable areas and dimensions and for particular actor groups
