With parks and protected areas insufficient to sustain global biodiversity, the role of private land in biodiversity conservation is becoming increasingly significant. This paper reviews global voluntary and involuntary strategies for private land conservation. Involuntary strategies can achieve effective conservation outcomes, but often lack social acceptability. In contrast, voluntary strategies enjoy greater social acceptance but may not achieve sufficient uptake to have meaningful conservation objectives. Based on the review, we propose a classification system for private land conservation as a complement to the International Union for Conservation of Nature's (IUCN's) classification of global protected areas. The classification system provides a framework for identifying and describing conservation strategies on private land on the dimension of tenure and security. It also identifies opportunities and vulnerabilities in achieving conservation on private land while emphasising the need for systematic data collection similar to IUCN's efforts for protected areas. 相似文献

Drawing from experiences gained from the development and implementation of four approved habitat conservation plans (HCPs), I describe the goals and strategies used by the nine local government members of the Riverside County Habitat Conservation Agency (RCHCA) to reconcile conflicts among a rapidly growing population and the need to conserve the habitat of a number of declining wildlife species in western Riverside County, California. Several important goals have been pursued by RCHCA member governments in their sponsorship of multiple-species habitat conservation plans (MSHCPs), including (1) establishing certainty and control over future uses of land; (2) eliminating project-by-project negotiations with federal and state wildlife agencies; (3) coordinating mitigation obligations under the Endangered Species Act, Clean Water Act, California Environmental Quality Act, and other federal and state laws; (4) reducing conflict and litigation resulting from land development activities; and (5) ensuring that wildlife conservation activities are conducted in a manner that permits local governments to perform those functions necessary to maintain public health, safety, and welfare. I also describe the emergence of strategies by local governments to achieve MSHCP goals, including (1) use of an inclusive planning process that seeks to build consensus among affected interests; (2) extensive involvement of federal and state wildlife agencies in the preparation of MSHCP documents; (3) management of public lands to support MSHCP conservation objectives; (4) encouragement of voluntary conservation by private property owners through incentive programs; and (5) active solicitation of federal and state funding for MSHCP implementation activities. 相似文献

ABSTRACT: South Florida and the Everglades have been under intensive development since 1850 by Federal and State governments who encouraged and financed extensive drainage and hydraulic changes, primarily for agricultural settlement. Agricultural development of the sugar industry in the northern Everglades adjacent to Lake Okeechobee rapidly progressed only after the 1900s. Political and resource management conflicts have arisen because policies which once favored development are now being reversed by policies and regulation efforts to restore and conserve natural ecosystems. Currently, the environmental and ecological impacts of agricultural land use adjacent to natural wtlands of the Everglades are being assessed. The objectives of this paper are: (1) to outline the historical development of south Florida and the sugar industry, (2) to relate this history to political and management policy changes occurring as it pertains to ecosystem restoration and the multiuser competition for water/land resources, and (3) to propose how integrated resource management might be utilized for a sustainable Everglades and south Florida. This paper outlines the historical paradox of urban settlement, land development, and agricultural production, with efforts in the recent decade to acquire, manage, and preserve land and water resources for natural areas conservation. Only though the use of integrated resource management will the defined resource conflicts be mediated. 相似文献

Biodiversity Conservation,Ecosystem Services and Livelihoods in Tropical Landscapes: Towards a Common Agenda 总被引:1,自引:1,他引:0
Trade-offs between ecosystem conservation and agricultural production can more easily be addressed by shifting the view from
the plot scale to the scale of the landscape and integrating biodiversity friendly land use systems into development strategies.
The provision of ecosystem services such as watershed protection and carbon sequestration by natural and complex agro-ecosystems
can play an important role in making such integrated landscape approaches viable. This special issue brings together papers
that were presented at a symposium on agroforestry and landscape scale conservation at the Second World Agroforestry Congress
in Nairobi in August 2009. It is divided into two sections focusing on: (1) the biological mechanisms and implications of
landscape scale conservation strategies as influenced by land use, especially agroforestry; and (2) the economic drivers and
public policies that determine to a large extent the success of agroforestry-based landscape conservation strategies. The
contributions provide evidence both for the potential and limitations of agroforestry in landscape scale conservation and
development strategies and highlight the importance of economic incentives and policies to promote integrated landscape solutions.
This introductory paper summarizes and discusses the contributions and concludes with policy recommendations and research
needs. 相似文献

Future conservation efforts will need to transcend geopolitical boundaries in efforts to protect entire landscapes and ecosystems. Neotropical migratory birds are as a group a useful conservation tool for linking diverse landscapes and people due to their dependence on multiple habitats, sensitivity to habitat changes, and universal public appeal. The conservation of neotropical migrants can therefore function as a powerful hemispheric umbrella for ecosystem protection. Efforts to protect neotropical migratory birds on their nonbreeding grounds have traditionally been focused on Mexico, Central America, and the Caribbean. To assess the importance of South America to neotropical migrants, an ecoregional classification system was used to determine species distributions in the Andean/Southern Cone Region (Bolivia, Colombia, Ecuador, Paraguay, Peru, and Venezuela). The occurrence of migrants in protected areas that are part of The Nature Conservancy's Parks in Peril program was also assessed. Of the 406 neotropical migrant species, nearly one third (132) occur as regular nonbreeding residents in the region and for almost half of these species (53), South America is their main nonbreeding ground. All Parks in Peril sites were found to harbor neotropical migrants. Forty-eight species (36%) have declining longterm North American Breeding Bird Survey population trends and/or high Partners in Flight concern scores and thus are of significant conservation concern. Most importantly, 29 species (22%) of conservation concern use South America as their primary nonbreeding ground, indicating a need for focused conservation action. The nature of the ecoregional approach used in this endeavor makes future prioritization of ecoregions and conservation strategies for neotropical migrants across national boundaries possible. The ability to link diverse landscapes using a common element such as migratory birds allows for unique transboundary partnerships and opportunities for habitat conservation, which support the goal of the Conservancy's new Migratory Bird Initiative. 相似文献

Summary In the spring of 1981, Tufts University and the International Union for the Conservation of Nature began teaching the World
Conservation Strategy to environmentalists working at the local level. The fourteen-week course that they offered was the
first of a series of initiatives to increase public awareness of the need for local action toward the solution of global environmental
problems. The success of the first course has encouraged other groups to adapt it to their own social and ecological settings,
but there is a pressing need for even more public education. While several aids to teaching the World Conservation Strategy
are now being developed to give local conservation educators access to the Strategy, the initiative for bringing the World
Conservation Strategy to the public should continue to come from these local leaders.
Frank Thibodeau is an environmental biologist and policy analyst with MA and PhD degrees from Tufts University. He is currently
a Research Associate in the Department of Urban and Environmental Policy at Tufts, preparing a book on the World Conservation
Strategy as a foundation for local environmental initiative under the auspicies of IUCN and the World Wildlife Fund. In addition
to his writing and teaching related to the Strategy, he maintains an active research program examining the development of
national and international strategies for the preservation of genetic diversity.

Outreach nurseries are favored conservation and social forestry tools globally, but, as with many integrated conservation
and development programs (ICDPs), they do not always produce anticipated results. A synopsis of the experience of South African
practitioners is provided in this study of 65 outreach nurseries. South African outreach nurseries frequently include financial
objectives, creating additional challenges in simultaneously attaining conservation and socioeconomic goals. Progress was
hindered by biophysical problems (e.g., lack of water, poor soils, etc.) as well as the harsh socioeconomic conditions facing
most communities in which nurseries had been established. Attaining financial viability was challenging. Business management
skills were often restricted, and few viability studies included adequate market research. Costs to community participants
were usually high, and benefits were limited. Conservation objectives were frequently lost in the struggle to attain financial
viability. The management of social processes also proved challenging. Although small scale and relatively straightforward
compared with many ICDPs, nurseries usually require substantial institutional support, including a range of technical, business,
and development services. Project time frames need to be reconsidered, as practitioners estimate that it takes 5–10 years
for nurseries to start meeting objectives, and donors and implementing agencies often operate on 2–3-year project cycles.
Detailed viability studies are essential, incorporating a social probe and an assessment of potential impacts of projects
on community participants. Progress needs to be continuously evaluated to enable institutions and community participants to
adapt to changing conditions as well as ensure that the spectrum of objectives are being achieved. 相似文献

An important aspect of developing a philosophical foundation for management of reserves using an ecosystem approach is the exploration of the relationship of ecosystem management strategies to the need for conservation of species of special concern Colonial water birds are species that may deserve special consideration They occur in over 25 US national parks, but in no case do the parks have a monopoly on the total protection or management of these birds As an agency responsible for such populations, the National Park Service engages in activities such as inventory, monitoring, research, and management, using an ecosystem management philosophy Most parks contain only segments of natural ecosystems, and management actions, even those undertaken from an ecosystem perspective, may not be in the best interest of an individual species Management strategies for widely ranging special species require a regional perspective, including plans that take into consideration the differing objectives of the agencies responsible for such species A matrix of the different management strategies in various areas may provide a suitable, perhaps the best, method for protecting special species In practice, any one strategy, such as management of remnant ecosystem patches or intensive single-species management, may not be successful alone 相似文献

Nepal is considered a leader among developing nations with regard to conservation legislation and programs; it was among the
first Asian nations to develop national conservation legislation, sign CITES, and develop a national conservation strategy.
We review the history of modern conservation law in Nepal from the Rana period (early 1950s) to the present. The early legislation
focused mainly on strict preservation of areas and species; this phase culminated in the National Parks and Wildlife Conservation
Act of 1973. Subsequent legislation has evolved more in the direction of an integrated, holistic approach to conservation
and is beginning to incorporate the participation of local people; subsequent amendments to the 1973 act allowed greater rights
to rural villagers, and the designation of conservation areas in addition to the more strictly defined protected areas (national
parks, wildlife reserves, etc.).
Our review of conservation legislation suggests that Nepal has had many successes to date; the country has a protected area
system covering over 10% of its land area, and many target species are recovering in parks and reserves. There are also some
causes of concern, including staff shortages, financial constraints within the Department of National Parks and Wildlife Conservation,
and the fact that there is little legal infrastructure outside of protected areas to enforce conservation laws; further, some
aspects of hunting regulations are in need of revision. Primary needs include a comprehensive review of these policies and
a nationalized strategy to ameliorate the shortcomings. 相似文献

Planners are being called on to prioritize marine shorelines for conservation status and restoration action. This study documents
an approach to determining the management strategy most likely to succeed based on current conditions at local and landscape
scales. The conceptual framework based in restoration ecology pairs appropriate restoration strategies with sites based on
the likelihood of producing long-term resilience given the condition of ecosystem structures and processes at three scales:
the shorezone unit (site), the drift cell reach (nearshore marine landscape), and the watershed (terrestrial landscape). The
analysis is structured by a conceptual ecosystem model that identifies anthropogenic impacts on targeted ecosystem functions.
A scoring system, weighted by geomorphic class, is applied to available spatial data for indicators of stress and function
using geographic information systems. This planning tool augments other approaches to prioritizing restoration, including
historical conditions and change analysis and ecosystem valuation. 相似文献

Extensive research has been conducted globally into conceptual frameworks for ecosystem services, the most notable being the
Millennium Ecosystem Assessment (Millennium ecosystem assessment: ecosystems and human well-being; a framework for assessment.
World Resources Institute, Washington, DC, pp 51, 53–55, 2005). The South East Queensland (SEQ) Ecosystem Services Framework (Australia) aims to provide the tools to enable government,
industry, business, researchers, non-government organizations and land managers to apply the concept of ecosystem services
in their planning and management practices. This article describes the Framework and the process that has produced matrices
and maps that identify and illustrate the linkages between ecosystems, ecosystem functions, ecosystem services and the community’s
well-being. The matrices and maps derived can identify areas in the region where the most ecosystem services are generated.
This allows areas to be considered as valuable natural assets of the region, deserving appropriate protection measures or
significant offsets if they are diminished or degraded in any way. Although the Framework requires further refinement and
ongoing development, the process applied and the products produced has enabled decision makers to turn the concept of ecosystem
services into practical application in SEQ. 相似文献

Evaluation model for developing,implementing, and assessing conservation education programs: Examples from Belize and Costa Rica 总被引:1,自引:0,他引:1
Susan K. Jacobson 《Environmental management》1991,15(2):143-150
Evaluation of conservation education programs can: (1) provide accountability in demonstrating a program's worth, (2) offer
an opportunity for receiving feedback and improving programs, (3) further our understanding of the process of program development,
and (4) promote conservation education by substantiating claims about its benefits. The Planning-Process-Product systems evaluation
model provides feedback needed for making decisions about the development, implementation, and outcome of a program. Planning
evaluation was useful in assessing the needs, goals, opportunities, and constraints of a number of programs in Costa Rica
and Belize, such as a forestry education project and a zoo outreach program. It provided a basis for making planning decisions
incorporating specific objectives, such as the reforestation of a region or a change in knowledge and attitudes in program
participants. Process evaluation provided a Costa Rican sustainable development program with feedback during its implementation
and enabled it to modify and improve its newsletter for local farmers and its ecology classes for school children. Product
evaluation assessed project accomplishments, such as the $700,000 raised by the Children's Rainforest group and the 20 miles
of riparian land under conservation management as part of the Belize Community Baboon Sanctuary project. Outcomes are compared
with the programs original monetary or land management objectives to determine the success of the programs and to provide
feedback for improvement. 相似文献

Sub‐Saharan Africa continues to face the daunting challenge of alleviating poverty due to slow economic growth. In southern Africa, most countries are adopting policies that promote the integration of biodiversity conservation and rural development to contribute to rural poverty alleviation. Numerous approaches have been undertaken in this endeavour, including Transfrontier Parks (TFPs) and Transfrontier Conservation Areas (TFCAs). This paper discusses some of the limitations of the TFPs. In conclusion I posit that unlike TFPs, which are state controlled and managed, TFCAs, which promote multi‐land use and multi‐stakeholder participation are attainable and have a higher probability of sustaining biodiversity conservation and contributing to the alleviation of rural poverty, if: (i) areas of high biodiversity conservation within communal areas can be identified, zoned and leveraged to biodiversity conservation and managed in partnership between the communities and the private sector; (ii) local communities can secure legal rights to their customary land being devoted to biodiversity conservation and use such pieces of land as collateral in negotiating partnerships with the private sector in developing conservation‐based enterprises; (iii) functional community natural resource governance institutions can be established and empowered to represent their constituencies in securing fair equity from profits made from sustainable use of the conserved biodiversity assets and tourism businesses; (iv) concerted effort can be invested in developing and implementing family planning and fertility reduction strategies that would slow down human population growth to levels that can be sustained by the available natural resources; and (v) if sustainable financing mechanisms can be developed, and the governance of protected areas occurring in the TFCAs can be broadened to include other stakeholders. 相似文献

Fragmentation of family-owned farms and ranches has been identified as the greatest single threat to wildlife habitat, water
supply, and the long-term viability of agriculture in Texas. However, an integrative framework for insights into the pathways
of land use change has been lacking. The specific objectives of the study are to test the hypotheses that the nonagricultural
value (NAV) of rural land is a reliable indicator of trends in land fragmentation and that NAV in Texas is spatially correlated
with population density, and to explore the idea that recent changes in property size patterns are better represented by a
categorical model than by one that reflects incremental changes. We propose that the State-and-Transition model, developed
to describe the dynamics of semi-arid ecosystems, provides an appropriate conceptual framework for characterizing categorical
shifts in rural property patterns. Results suggest that changes in population density are spatially correlated with NAV and
farm size, and that rural property size is spatially correlated with changes in NAV. With increasing NAV, the proportion of
large properties tends to decrease while the area represented by small properties tends to increase. Although a correlation
exists between NAV and population density, it is the trend in NAV that appears to be a stronger predictor of land fragmentation.
The empirical relationships established herein, viewed within the conceptual framework of the State-and-Transition model,
can provide a useful tool for evaluating land use policies for maintaining critical ecosystem services delivered from privately
owned land in private land states, such as Texas. 相似文献

Environmental service payments: evaluating biodiversity conservation trade-offs and cost-efficiency in the Osa Conservation Area, Costa Rica 总被引:1,自引:0,他引:1

The cost-efficiency of payments for environmental services (PES) to private landowners in the Osa Conservation Area, Costa Rica, is evaluated in terms of the trade-off between biodiversity representation and opportunity costs of conservation to agricultural and forestry land-use. Using available GIS data and an 'off-the-shelf' software application called TARGET, we find that the PES allocation criteria applied by authorities in 2002-2003 were more than twice as cost-efficient as criteria applied during 1999-2001. Results show that a policy relevant assessment of the cost-effectiveness of PES relative to other conservation policies can be carried out at regional level using available studies and GIS data. However, there are a number of data and conceptual limitations to using heuristic optimisation algorithms in the analysis of the cost-efficiency of PES. Site specific data on probabilities of land-use change, and a detailed specification of opportunity costs of farm land, labour and capital are required to use algorithms such as TARGET for ranking individual sites based on cost-efficiency. Despite its conceptual soundness for regional conservation analysis, biodiversity complementarity presents a practical challenge as a criterion for PES eligibility at farm level because it varies depending on the set of areas under PES contracts at any one time. 相似文献

Given the nature of modern conservation acquisitions, which often result from gifts and opportunistic purchases of full or partial property rights, there is a risk that the resulting mosaic of conserved resources may not represent a coherent set of public values and benefits. With different public and private entities engaged in land conservation, one would further expect that each organization would apply separate goals and criteria to the selection and acquisition of its conservation portfolio. This set of circumstances raises an important question: what is the aggregate outcome of this land conservation process? Retrospective assessments provide a means of reviewing cumulative historical decisions and elucidating lessons for improving future conservation strategies. This study used GIS-based spatial analysis to examine the relationships of private and public conservation lands in Maine to a variety of landscape metrics in order to determine the degree to which these lands represent core ecological and socioeconomic values that are meaningful to a wide cross-section of citizens. Results revealed that the gains of past conservation efforts in Maine are counter-balanced to some extent by apparent gaps in the existing fabric of conservation holdings. Conservation lands capture a representative sample of diverse habitat, provide a large measure of protection for multiple conservation values and indicators, and offer an unusual mix of outdoor recreational opportunities for residents and visitors alike. Yet, the majority of parcels are relatively small and isolated, and thus do not provide contiguous habitat blocks that offset ongoing processes of landscape fragmentation. Furthermore, the majority of area associated with many of the ecological metrics examined in this report is located outside the boundaries of current conservation holdings. The under-represented metrics identified in this investigation can be viewed as potential targets for new strategic conservation initiatives. 相似文献

This study explores how conservation and development are interlinked and quantifies their reciprocal trade-offs. It identifies interventions which hold a promise to improve both conservation and development outcomes. The study finds that development trajectories can either be at the cost of conservation or can benefit conservation, but in all cases sustained poverty negatively affects conservation in the long term. Most scenarios with better outcomes for conservation come at a cost for development and the financial benefits of payments for environmental services (PES) are not sufficient to compensate for lost opportunities to earn cash. However, implementation of strategies for reducing emissions from deforestation and forest degradation in locations with low population densities come close to overcoming opportunity costs. Environmental services and subsistence income enhance the attractiveness of conservation scenarios to local people and in situations where these benefits are obvious, PES may provide the extra cash incentive to tip the balance in favor of such a scenario. The paper stresses the importance of external factors (such as industrial investments and the development of the national economy) in determining landscape scale outcomes, and suggests a negotiating and visioning role for conservation agencies. 相似文献

Agricultural conservation easements (ACEs) involve the significant expenditure of public funds through either tax benefits and/or direct public expenditures. The selection of agricultural parcels for conservation should, therefore, maximise net public benefits to the extent possible within financial constraints and the need for agricultural viability to maintain working landscapes. Some programmes select agricultural parcels for conservation easements based only on agricultural viability and/or land cost, however, without explicit consideration of the many other public benefits often associated with ACEs. This paper illustrates application of a method for increasing the public benefits of agricultural conservation easements through a case study in the northern San Joaquin Valley of California. The method is a strategic planning process that incorporates both a GIS-based quantitative assessment and a more qualitative assessment. Such an approach is a supplement to – rather than a substitute for – the more science-based Landscape Evaluation and Site Evaluation (LESA) approach developed by the US Soil Conservation Service (SCS) and cost-minimisation approaches that emphasise economic considerations. However, we show that public land use planning and regulatory policies are essential for agricultural conservation. Acquisition strategies in isolation will not be successful without complementary public regulatory policies. 相似文献

The Chinese government initiated a massive conservation program called “Grain-for-Green” in 1999 to reduce soil erosion and improve ecosystem function. Implementing practical sustainable development in the loess plateau still remains problematic, particularly in its eco-fragile areas. Here we discussed an approach for sustainable development at the watershed scale by integrating land use suitability, ecosystem services and public participation in the loess hilly area. We linked land use scenario analysis and economic modeling to compare the outcomes of three scenarios, CLU (Current Land Use), GOLU (Grain-production Oriented Land Use) and PSLU (Potential Sustainable Land Use). The results indicated that compared to PSLU, GOLU may provide a higher economic productivity in the short-term, but not in the long-term. CLU ranked lowest in terms of economic benefits and did not meet the daily needs of the local farmers. To reconcile the land use adjustments with farmers’ basic needs, a labor-saving land use strategy is necessary. Since the PSLU scenario assumes that slope cropland should be converted to pastures or orchards, more time may be available for off-farm work and for more public participation in integrated ecosystem management. Financial support to the local farmers for environmental conservation should be modulated in function of their positive contribution to ecosystem management. 相似文献

Habitat Conservation Plans (HCPs) under the Endangered Species Act (ESA) are an important mechanism for the acquisition of land and the management of terrestrial and aquatic ecosystems. HCPs have become a vital means of protecting endangered and threatened species and their habitats throughout the United States, particularly on private land. The scientific consensus that climate is changing and that these changes will impact the viability of species has not been incorporated into the conservation strategies of recent HCPs, rendering plans vulnerable biologically. In this paper we review the regulatory context for incorporating climate change into HCPs and analyze the extent to which climate change is linked to management actions in a subset of large HCPs. We conclude that most current plans do not incorporate climate change into conservation actions, and so we provide recommendations for integrating climate change into the process of HCP development and implementation. These recommendations are distilled from the published literature as well as the practice of conservation planning and are structured to the specific needs of HCP development and implementation. We offer nine recommendations for integrating climate change into the HCP process: (1) identify species at-risk from climate change, (2) explore new strategies for reserve design, (3) increase emphasis on corridors, linkages, and connectivity, (4) develop anticipatory adaptation measures, (5) manage for diversity, (6) consider assisted migration, (7) include climate change in scenarios of water management, (8) develop future-oriented management actions, and (9) increase linkages between the conservation strategy and adaptive management/monitoring programs. 相似文献
