The World Conservation Union (IUCN) plays a global leadership role in defining different types of protected areas, and influencing how protected area systems develop and are managed. Following the 1992 World Parks Congress, a new system of categorizing protected areas was developed. New categories were introduced, including categories that allowed resource extraction. Since that time there has been rapid growth in the global numbers and size of protected areas, with most growth being shown in the new categories. Further-more, the IUCN has heralded a ‘new paradigm’ of protected areas, which became the main focus of the 2003 World Parks Congress. The paradigm focuses on benefits to local people to alleviate poverty, re-engineering protected areas professionals, and an emphasis on the interaction between humans and nature through a focus on the new IUCN protected area categories.The purpose of this paper is to examine critically the implications of the new categories and paradigm shift in light of the main purpose of protected areas, to protect wild biodiversity. Wild biodiversity will not be well served by adoption of this new paradigm, which will devalue conservation biology, undermine the creation of more strictly protected reserves, inflate the amount of area in reserves and place people at the centre of the protected area agenda at the expense of wild biodiversity. Only IUCN categories I–IV should be recognized as protected areas. The new categories, namely culturally modified landscapes (V) and managed resource areas (VI), should be reclassified as sustainable development areas. To do so would better serve both the protection of wild biodiversity and those seeking to meet human needs on humanized landscapes where sustainable development is practised.

Climate change may affect important environmental components of holiday destinations, which might have repercussions for tourism-dependent economies. This study documents the importance of environmental attributes in determining the choice and holiday enjoyment of tourists visiting Bonaire and Barbados, two Caribbean islands with markedly different tourism markets and infrastructure. Three hundred and sixteen and 338 participants from Bonaire and Barbados, respectively, completed standardized questionnaires. Warm temperatures, clear waters and low health risks were the most important environmental features determining holiday destination choice. However, tourists in Bonaire thereafter prioritized marine wildlife attributes (i.e. coral and fish diversity and abundance) over other environmental features, whereas tourists in Barbados exhibited stronger preferences for terrestrial features, particularly beach characteristics. The willingness of tourists to revisit these islands was strongly linked to the state of the preferred environmental attributes. More than 80% of tourists in Bonaire and Barbados would be unwilling to return for the same holiday price in the event, respectively, of coral bleaching as a result of elevated sea surface temperatures and reduced beach area as a result of sea level rise. Climate change might have a significant impact on Caribbean tourism economy through alteration of environmental features important to destination selection. Island-specific management strategies, such as focusing resources on the protection of key marine or terrestrial features, may provide a means of reducing the environmental and economic impacts of climate change.

Although the importance of hedgerows for sustainable agriculture and conservation of rural biodiversity is increasingly being recognized, obtaining insight into the spatial and temporal dynamics of hedgerow networks remains an important challenge for landscape ecologists, with the key factors driving changes in rural landscape structure especially deserving further attention. The present study analyses the long-term history of a hedgerow network landscape in Flanders, Belgium. A detailed reconstruction of the hedgerow network is made at five points in time, starting at the end of the 18th century until present, for 367 distinct 400 m×400 m samples. Whilst hedgerows were mainly concentrated around historical village centres and within valleys at the end of 18th century, the network expanded progressively during the 19th century. In the 20th century, the hedgerow network degraded strongly, with hedgerow density and connectivity declining and mesh-size heterogeneity and network fragmentation increasing, although the network recovered slightly during the 1990s. Different trajectories of change in hedgerow network structure were observed depending on landscape position, with both topography and village proximity significantly affecting hedgerow network dynamics. The present network structure was mainly governed by land use, with highly developed networks being predominantly associated with pasture. Three main conclusions arise from the results of this study. First, the role of land use and landscape position as basic factors steering hedgerow network dynamics at the landscape scale is demonstrated. Second, the long-term perspective of the study enabled insight into the poorly known expansion phase of hedgerow networks, linked mainly with the development of small-scale labour-intensive agriculture. Finally, the findings confirm the large-scale degradation of linear semi-natural habitats in European agricultural landscapes during most of the 20th century, and indicate that a pro-active rural policy can halt and even reverse this process.

Human activities within fluvial corridors and surrounding landscapes have persistently stressed riparian ecosystems, particularly in Iberian Mediterranean-type streams. The impact of human disturbance relative to natural environmental factors in shaping riparian vegetation is still poorly understood. Both regional variables (such as altitude and precipitation), and site-specific characteristics (such as substrate and riverbank modifications) were analysed as potential determinants of riparian vegetation patterning to determine the relative influences of the diverse land-use types and environmental factors on the composition (including floristic species richness and percentage cover of trees, shrubs and woody climbers) and integrity (width of riparian woods and patterns of longitudinal continuity) of riparian woods in eight river basins of the Tagus fluvial system (Portugal). There was patchy establishment of riparian woods, with generally low average width and low species richness, as well as significant inter-basin differences and upstream-downstream variations in riparian features. Species distribution was clearly determined by environmental factors, such as human disturbance on the riverbanks and geological background, and the environmental variables and the land use in the river valley partially explained the integrity of riparian woody vegetation. The results highlight the predictive capability of reach-level features; it appears that, linked with the geomorphological and climate context, small-scale human disturbances on riparian corridors play a major role in explaining the remaining biological variability.

Non-compliance with marine protected area (MPA) regulations is a problem worldwide, and this is being addressed through community programmes. Park service and fisheries department personnel, and fishers living adjacent to three parks were studied to determine their perceptions of MPAs. The hypotheses that positive perceptions towards the management of fisheries exclusion and gear-restricted areas would increase with the wealth, education, age and years of employment of the person, the history of community participation and the age of the MPA were tested. The strongest factor was employment, with fishers having significantly less positive perceptions towards areas closed to fishing than government managers, although all groups agreed area management benefited the nation. Government personnel thought that fishers and their communities benefited from area management, while most fishers did not share this view. Increasing wealth or community participation were not significant factors, but secondary education was associated with more positive perceptions of area management. Fishers adjacent to the oldest MPA held significantly more positive perceptions than fishers living adjacent to the newest MPA, although only a slight majority agreed that they and their communities benefited. The results point to a need for patience in expecting change in resource users' perceptions, adopting an approach in which there is more communication between fishers and managers, so that both are more aware of MPA functions, particularly closed areas and the indirect benefits.

Conflict between wildlife and people can erode local support for conservation. Wildlife-based benefits are intended to offset costs and encourage tolerance or stewardship, but where the linkage between benefits and wildlife is not understood, benefits may be ineffective at bolstering conservation. In Laikipia, Kenya, wildlife and areas devoted to wildlife are on the increase, but most residents still suffer losses to wildlife and derive minimal benefits. The elephant situation is particularly problematic because elephants may compete with livestock for resources, raid people's crops, and chase and kill livestock and people. Although most unprotected elephant range in East Africa is in semi-arid rangelands occupied by pastoralists, previous research has emphasized agricultural, not pastoral or agri-pastoral conflicts. Between 1999 and 2002, interviews were conducted in Laikipia District to examine whether pastoralists also experience conflict, and to determine whether wildlife conservation provided appreciable benefits to residents, or fostered pro-conservation attitudes among residents. Three properties, Endana, Koija and Mpala, were selected to include the two primary land uses in Laikipia (livestock and agriculture) and two levels of wildlife-based benefits (indirect benefits and direct benefits from a locally-owned tourism operation). People were negative about many aspects of local wildlife conservation, especially animals that raided crops or were dangerous. Fundamental differences in attitudes were attributable to primary land use; within ethnic groups, people practising agriculture were less tolerant of elephants than people practising pastoralism. Despite evidence that elephants may compete with livestock for forage, ecological competition was not a primary concern among cattle-keeping people. In communities that received indirect benefits from tourism or wildlife, the connection between wildlife and employment or aid in kind was usually overlooked. Unlike elsewhere in Africa, education and wealth did not correlate with positive attitudes towards wildlife because the tourism programme was improving the situation and the outlook of people lacking education and material wealth. Pastoral people with indirect financial benefits expressed positive attitudes towards elephants for aesthetic reasons, while pastoral people with direct benefits cited financial rewards derived from tourism but attributed aesthetic values to living with elephants. The programme in the pastoral community receiving benefits was exemplary in that benefits were tangible, and the participants appreciated the linkage between benefits and active conservation. Land conversion from pastoralism to agriculture threatens elephant survival, not only in terms of habitat loss, but also in terms of lost tolerance among people who have shifted to farming.

New forest policies in South Africa seek to reconcile conservation and development objectives by devolving some responsibility for forest management from the state to local communities. Community participation in forest management aims to protect forest-based subsistence livelihoods by incorporating the interests of resource users, while simultaneously diffusing threats to biodiversity by managing resource use. To date, participatory forest management (PFM) has had mixed success in South Africa because the transfer of rights to users has not accompanied changes in policy. A questionnaire survey of 60 households (43%) revealed the attitudes of users toward current management and conservation options for iGxalingenwa forest. Users chose participatory forest management (52%) over community (25%) or state-dominated forest management (2%) structures. User choice was motivated by the desire to secure rights of access to, and ensure equitable benefit from, a dwindling resource base, rather than the conservation of these resources to sustain future yields. Users were unwilling to reduce resource use and compromise usufruct rights to achieve conservation goals, even to improve the availability of the resource stock. Current user needs compromise biodiversity conservation goals, and users regard state conservation practices as protectionist and obstructing their rights of access to resources. While the National Forests Act of 1998 seeks to conserve resources by limiting access to them and is based on principles of sustainable use, it is nevertheless perceived to offer few incentives to users to participate in forest management and conservation. Ideally, an institutional and legal framework that allocates user rights and managerial responsibilities to households is required, but clearly suitable alternatives to forest products are also vital for successful management. Greater trust between the provincial parks authority and users is needed, but is complicated by weak traditional leadership and poor community representation. Ultimately, users preferred PFM because, while recognizing that harvest rates are unsustainable, user dependence upon forest resources and weak traditional leadership means they can protect usufruct rights only by participation. Changes to any of these factors may create demands for a new management system. PFM allows the greatest flexibility for responding to changes in demands as well as the environment.

Fuelwood is still the primary energy source for rural households across the savannah biome of Africa. Coppice growth is an important species-specific trait that strongly influences fuelwood production and regeneration, and yet coppice growth patterns are poorly understood in African savannahs. It is therefore vital that factors affecting coppice growth of species, such as environment conditions and harvesting technique, be better understood in order to develop models for sustainable fuelwood use. This study investigated coppice growth and resource allocation strategies in relation to (1) position along the landscape catena and (2) harvesting technique, for three savannah fuelwood tree species: Dichrostachys cinerea, Albizia harveyi and Combretum collinum. The study was conducted in a dystrophic semi-arid savannah in the far north-east of South Africa. A total of 1146 harvested stumps were sampled in topland and bottomland sites in three locations around a rural village. Stump characteristics (diameter and height) and coppice shoot variables (number of shoots, length and diameter of each shoot, length of longest shoot, and diameter of fattest shoot) were measured for each stump. Three soil samples were taken in each site for physical and chemical analysis. No statistically significant differences were found in soil variables between topland and bottomland sites, probably due to low sample size. Coppice resource allocation strategies varied between species. D. cinerea exhibited a ‘quantity-driven’ strategy, with the production of large numbers of relatively small coppice shoots with high length:diameter ratio (shoot taper function). C. collinum exhibited a ‘quality-driven’ strategy, characterized by the production of a relatively low number of larger coppice shoots. Coppice growth variables for A. harveyi were intermediate between those of the other two species, suggesting a strategy where allocation of resources to the number and growth of shoots is more balanced. However, allocation of resources relative to the size of the cut stem, indexed by total shoot basal area:stump basal area ratio, did not differ significantly between species. Coppice growth was strongly favoured in bottomland sites for D. cinerea, and to a lesser degree, C. collinum. Catenal position had a negligible influence on coppice growth of A. harveyi. Number of shoots produced increased with cutting height for all three species. For all three species the number of shoots increased with stump diameter, and mean shoot size also increased with stump size for D. cinerea. There was a significant negative relationship between stump diameter and total shoot basal area:stump basal area ratio for A. harveyi and C. collinum. A framework for optimizing different coppice growth variables according to species, catenal position and harvesting technique is given.

The ecosystem services provided by mangroves are often ignored in the ongoing process of mangrove conversion. Services provided by the Bhitarkanika mangrove ecosystem in India and estimated cyclone damage avoided in three selected villages, taking the cyclone of 1999 as a reference point, were valued by assessing the socio-economic status of the villages, the cyclone damage to houses, livestock, fisheries, trees and other assets owned by the people, and the level and duration of flooding. Eleven variables were used to compare damage in the villages, one protected by mangroves, one unprotected by mangroves, and the third possessing an embankment on its seaward side. Attitude surveys were carried out in 10% of the households in 35 villages located in the Bhitarkanika Conservation Area to assess local people's perceptions regarding the storm protection function of mangroves and their attitude towards mangrove forests generally. In the mangrove-protected village, variables had either the lowest values for adverse factors (such as damage to houses), or the highest values for positive factors (such as crop yield). The loss incurred per household was greatest (US$ 153.74) in the village that was not sheltered by mangroves but had an embankment, followed by the village that was neither in the shadow of mangroves or the embankment (US$ 44.02) and the village that was protected by mangrove forests (US$ 33.31). The local people were aware of and appreciated the functions performed by the mangrove forests in protecting their lives and property from cyclones, and were willing to cooperate with the forest department in mangrove restoration.
