Regional environmental assessment (REA) and local Agenda 21 implementation

The implementation of sustainable development requires several support instruments. One of the major instruments in the Rio Declaration to support this process has been environmental assessment that has been given considerable emphasis as to its potential ability to help achieve more sustainable forms of development. Regional environmental assessment (REA) has shown to be effective in supporting local sustainable development process. Selected environmental assessment methods have been␣used to improve the REA exercise and provide reliable data for decision-making not only to correct environmental problems due to past unsustainable social-economic developments but also help local governments to implement Agenda 21 (AG21) plans and projects.     

Patterns of Citations of Open Access and Non‐Open Access Conservation Biology Journal Papers and Book Chapters

Abstract: Open access (OA) publishing, whereby authors, their institutions, or their granting bodies pay or provide a repository through which peer‐reviewed work is available online for free, is championed as a model to increase the number of citations per paper and disseminate results widely, especially to researchers in developing countries. We compared the number of citations of OA and non‐OA papers in six journals and four books published since 2000 to test whether OA increases number of citations overall and increases citations made by authors in developing countries. After controlling for type of paper (e.g., review or research paper), length of paper, authors’ citation profiles, number of authors per paper, and whether the author or the publisher released the paper in OA, OA had no statistically significant influence on the overall number of citations per journal paper. Journal papers were cited more frequently if the authors had published highly cited papers previously, were members of large teams of authors, or published relatively long papers, but papers were not cited more frequently if they were published in an OA source. Nevertheless, author‐archived OA book chapters accrued up to eight times more citations than chapters in the same book that were not available through OA, perhaps because there is no online abstracting service for book chapters. There was also little evidence that journal papers or book chapters published in OA received more citations from authors in developing countries relative to those journal papers or book chapters not published in OA. For scholarly publications in conservation biology, only book chapters had an OA citation advantage, and OA did not increase the number of citations papers or chapters received from authors in developing countries.     

Conservation Value of Sites of Hybridization in Peripheral Populations of Rare Plant Species

Abstract:  Populations at the periphery of a species' range are of interest to conservation biologists because they can show marked genetic differentiation from populations at the center of a range and because of potential hybridization among rare and common species. We examined two closely related Cyclamen species. One is a narrow endemic, and the other is more geographically widespread (both protected by law in continental southern France). We used floral traits and genetic variability to test for hybridization among the species in peripheral populations of the rare species. The species co-occurred on Corsica in a disjunct, peripheral part of the distribution of the endemic species and in an ecologically marginal area for the widespread species. The two species have hybridized and the endemic species showed high levels of introgression with its widespread congener. Genetic and floral variability in sites with both species was markedly higher than in sites with a single species. Our results highlight the need for a conservation strategy that integrates hybrid populations because they represent a source of novel diversity that may have adaptive potential.     

Effectiveness of Marine Protected Areas in the Philippines for Biodiversity Conservation

Abstract: Quantifying the extent to which existing reserves meet conservation objectives and identifying gaps in coverage are vital to developing systematic protected‐area networks. Despite widespread recognition of the Philippines as a global priority for marine conservation, limited work has been undertaken to evaluate the conservation effectiveness of existing marine protected areas (MPAs). Targets for MPA coverage in the Philippines have been specified in the 1998 Fisheries Code legislation, which calls for 15% of coastal municipal waters (within 15 km of the coastline) to be protected within no‐take MPAs, and the Philippine Marine Sanctuary Strategy (2004), which aims to protect 10% of coral reef area in no‐take MPAs by 2020. We used a newly compiled database of nearly 1000 MPAs to measure progress toward these targets. We evaluated conservation effectiveness of MPAs in two ways. First, we determined the degree to which marine bioregions and conservation priority areas are represented within existing MPAs. Second, we assessed the size and spacing patterns of reserves in terms of best‐practice recommendations. We found that the current extent and distribution of MPAs does not adequately represent biodiversity. At present just 0.5% of municipal waters and 2.7–3.4% of coral reef area in the Philippines are protected in no‐take MPAs. Moreover, 85% of no‐take area is in just two sites; 90% of MPAs are <1 km². Nevertheless, distances between existing MPAs should ensure larval connectivity between them, providing opportunities to develop regional‐scale MPA networks. Despite the considerable success of community‐based approaches to MPA implementation in the Philippines, this strategy will not be sufficient to meet conservation targets, even under a best‐case scenario for future MPA establishment. We recommend that implementation of community‐based MPAs be supplemented by designation of additional large no‐take areas specifically located to address conservation targets.     

Species Inequality in Scientific Study

Abstract: Some conservationists argue for a focused effort to protect the most critically endangered species, and others suggest a large‐scale endeavor to safeguard common species across large areas. Similar arguments are applicable to the distribution of scientific effort among species. Should conservation scientists focus research efforts on threatened species, common species, or do all species deserve equal attention? We assessed the scientific equity among 1909 mammals, birds, reptiles, and amphibians of southern Africa by relating the number of papers written about each species to their status on the International Union for Conservation of Nature Red List. Threatened large mammals and reptiles had more papers written about them than their nonthreatened counterparts, whereas threatened small mammals and amphibians received less attention than nonthreatened species. Threatened birds received an intermediate amount of attention in the scientific literature. Thus, threat status appears to drive scientific effort among some animal groups, whereas other factors (e.g., pest management and commercial interest) appear to dictate scientific investment in particular species of other groups. Furthermore, the scientific investment per species differed greatly between groups—the mean number of papers per threatened large mammal eclipsed that of threatened reptiles, birds, small mammals, and amphibians by 2.6‐, 15‐, 216‐, and more than 500‐fold, respectively. Thus, in the eyes of science, all species are not created equal. A few species commanded a great proportion of scientific attention, whereas for many species information that might inform conservation is virtually nonexistent.     

Proliferation of nonconforming land uses in agricultural envelope of urban Hong Kong

Until the late 1960s rural Hong Kong had an attractive rustic landscape and a small but active farming population. The recent widespread agricultural decline provided opportunities for urban-oriented activities to invade, mainly as open storage and workshops unsuitable in city areas. Rapid container-port expansion and cross-border China trade generate demands for cheap and accessible land for non-conforming uses (NCU). Rural development control and land-use planning are inherently weak, and formal provision for such uses is lacking. An unfavorable landmark court judgement allows landowners to degrade the countryside. The activities have caused acute environmental problems, telescoped into a small territory, including visual blight, pollution, drainage blockage, loss of wetland habitats, and increased flooding hazard. The distinction between urban and rural has been blurred in the destruction of the valuable countryside heritage. An interim legislative amendment fails to stop unauthorized conversion of farmland. In the long term, an integrated and comprehensive rural planning strategy to conserve inherent elements, as well as accommodating selected urban spillover in properly located and serviced sites, is needed.     

Salt river project's participation in Arizona's bald eagle conservation efforts

Bald eagle (Haliaeetus leucocephalus) conservation in Arizona, USA, is a prime example of a successful, cooperative environmental management effort. The Salt River Project (SRP) is an active participant in the statewide bald eagle management activities. This paper summarizes the major components of the statewide program and highlights SRP's participation in these efforts. The Southwestern Bald Eagle Management Committee (SWBEMC) was formed as a means of coordinating interagency projects. Chaired by the Arizona Game and Fish Department (AGFD), the SWBEMC is comprised of 15 state, federal, tribal, and private agencies. Together, these agencies sponsor the Nest Watch Program, a unique and effective program dedicated to the study, conservation, and recovery of bald eagles in the southwest. Other significant components of the bald eagle management program include nest monitoring, nest search activities, winter counts, and demography studies.

Devolving power from the state: local initiatives for nature protection and recreation in Sweden

ABSTRACT

Quests for devolving more power to local actors for nature protection stem from both international and national policies. Also, there is a growing recognition of the need for local governments to promote green infrastructure for citizens to recreate and learn about their environment. Starting in 2004, the Swedish government has allocated special funding towards these goals through the Local Nature Conservation Programme (LONA). Virtually all Swedish municipalities have received such funding in pursuit of facilitating wide access to nature and promoting recreational activities, including the protection of nature areas, creating pathways, information devices, and promoting these areas among new societal groups to enjoy. This study presents the results of ten years of experience with LONA. A survey with respondents from 191 municipalities and 20 county administrations, together with 20 key informant interviews, show that the programme has been a success in several respects. Not only have most municipalities created a wealth of new ways to engage local organisations and citizens in nature conservation and recreation, but they have also broadened the ways they think about how nature is important to their constituencies. Due to innovative ways to count voluntary work as local matching of funding, smaller and less resourceful municipalities have also become engaged. Still, the local needs for further initiatives are deemed considerable. State support coupled with knowledge sharing is important to show policy priority to such bottom-up initiatives.     

RATIONAL PROTECTION OF WATER RESOURCES IN COASTAL ZONES THROUGH PLANNED DEVELOPMENT1

ABSTRACT: A significant water-resources problem in Florida and other coastal states where the ground-water resources are threatened by salt-water intrusion or direct pollution from septic tanks, canals or marinas, is the almost explosive urban development of the limited coastal zone without or with only little water related planning. The reported study deals with the establishment of methods for identification of areas which are suitable for development and of areas where complete preservation or controlled and limited development should be encouraged. A methodology using data input available from such federal and state agencies as the USGS, the U. S. Weather Bureau, and the various State Geological Surveys is developed and brought on a graphic form that will guide the planning process and allow the urban planner even without a background in geohydrology or water-resources engineering to identify the problem areas.
