The conservation and management of protected areas in urban settings has become increasingly challenging with dynamics over land use change in adjacent urban areas being highly relevant to, but at times conflicting with, the protected area. This study seeks to better understand the implications of land use change processes to urban protected area management through the case study of the Las Piñas – Parañaque Critical Habitat and Ecotourism Area (LPPCHEA) in Metro Manila, Philippines. Factors and processes influencing land use change and protected area management and the impact of stakeholders’ perceptions on protected area were analyzed. The urban protected area in itself has limited influence on its surrounding urban areas, as land use change in these areas is shaped more by social, economic and policy/institutional factors occurring within the context of urban-regional development. The study also found that land use conflict is evident in an urban protected area due to the competing ecosystem services derived by various stakeholders. This discord is deepened by the lack of coordination between land use planning and protected area management. Integrating protected area management with land use planning through legally binding instruments, specific timeframes and clear internal procedures can help resolve land use conflict for an urban protected area at the strategic or policy level.  相似文献

Evaluation of the management effectiveness of protected areas has become a global priority, especially in coastal zones, where essential services are threatened by land use pressures. To assess the effectiveness of a coastal protected area, we estimated the land-use change (LUC) within and outside of the Pantanos de Centla Biosphere Reserve (PCBR) and interviewed key stakeholders to identify the main stressors causing LUC. The native vegetation cover under the PCBR protection decreased by 65% over 24 years; whereas agriculture and livestock lands doubled, even within the core conservation areas of the PCBR. The greatest loss was in the flooded forest (48%), where the reduction was similar in and around the reserve. The effectiveness of reserve management was affected by drivers of land use change, which include agricultural and livestock enterprises that are run by government programs. Effective management of the PCBR has been undermined by poor management practices, limited capacity and resources, and inadequate zoning design. Protected areas and its surrounding landscapes could be considered to be natural experiments for future research, where high value land uses and conservation objectives coincide within coastal areas that will face a predicted sea level rise, more intense floods and higher temperatures.  相似文献

The latest theories on the governance of water resources point to the need to adopt integrated approaches, allowing the mediation of conflict between public and private interests by building consensus to include the participation of stakeholders and civil society in formulating and implementing policies, thereby ensuring their legitimacy. Models of governance have particular relevance in the context of estuaries, because of the complexity associated with them. Estuaries are areas where valuable, highly sensitive and diverse natural systems coexist, which are frequently threatened by the numerous human activities concentrated there. They are also areas where several organizations overlap, with their own jurisdictions and management instruments and where there is a wide range of users with distinct interests. At a time when the Planos de Ordenamento de Estuários (POE) (Estuary Land Use and Management Plan), a new tool for water resource management and planning, are being drawn up in Portugal, this paper discusses the specificities of the new Portuguese estuary plans, as well as associated potentials and constraints to further understand how water resources and land use policies may effectively be integrated in estuary contexts. It critically analyses the Portuguese legal framework established for these plans, arguing that, in spite of the novelty of the newly defined legal measures to better plan and manage estuaries, implementation of its ambitious objectives requires a robust governance model for plan preparation and implementation. Taking into account the main institutional features of complex estuaries with various agencies, stakeholders and users, as well as relevant governance principles, this paper proposes a governance model capable of enriching the implementation of estuary plans by contributing to a stronger involvement of all stakeholders and users in the construction of the plan, allowing conciliation of interests and participation in decision-making, within a framework of collaborative governance. Whilst the paper focuses on the Portuguese Law, the approach adopted is also of interest to other countries to assessing estuary planning regulations and associated collaborative measures.  相似文献

Aspects of governance of non-wood forest products (NWFPs) include institutional rules, stakeholder arrangements, and decision-making processes that govern production systems from access to resources, their use, and to markets. Compared with other forest products, few studies have investigated the governance of NWFPs in European post-socialistic countries transitioning from a planned to a market economy. This study compares institutional frameworks and stakeholder arrangements related to NWFPs in Russia and Ukraine using a case study approach. Both countries have a legacy of top-down forest government, state-owned forests, and rural communities with a long dependence on plant- and animal-based NWFPs. We analysed legal documents for NWFPs in each country and conducted expert interviews with stakeholders from the public, private, and civil sectors involved in the decision-making process of NWFPs. Institutional frameworks for NWFPs in both countries are complex, unclear, and overlap. Multiple legal documents contain restrictions regarding the extraction and sustainability of NWFPs. However, no special laws or policies are solely for NWFPs; all measures are included in legislation that regulates nature conservation and forest management. The government of both countries tends to overlook non-industrial forest use undertaken by marginal local communities, even if economic, social, and cultural values of NWFPs are relatively high for local and regional development. A misfit is observed between legal frameworks and forest companies’ business policies with customary rights. This phenomenon caused a shift to introduce new stakeholder arrangements related to NWFPs as a special type of resource in areas where NWFPs are heavily used both for subsistence and for generating household income by local communities. Landscape approach initiatives such as model forests and biosphere reserves may empower local communities to find means to protect their rights, needs, interests, and values related to NWFPs.  相似文献

As central policies for biodiversity conservation in agricultural landscapes in the European Union (EU), the Habitats Directive and Agri-environmental programmes (AEP) have largely failed to halt biodiversity loss. In response, the German federal state of Saxony combined the instrument of management plans with AEPs to support the implementation of the Habitat Directive. In this study, we investigate the determinants of a farmers’ decisions to adjust their farming practices. Our data set consists of a quantitative survey with 131 farmers conducted between 2004 and 2011, complemented by implementation data from 333 grassland-plots. Determinants of farmers’ decisions to conserve grassland were estimated using a multinomial logit model. Our results show that a combination of management plans and AEPs can increase farmers’ disposition to adopt nature conservation measures. As central determinants, structural and location factors as well as the complementary provisiion of specifically designed AEPs increase farmers’ willingness to adopt conservation practices for grassland management. It can be concluded that additional costs are a major barrier to farmers’ adoption, particularly to those farms directing their farm management towards the optimisation of productivity and profitability . The findings highlight the complementary potential of integrated policy packages to incentivise specific measures of nature conservation within the framework of the Habitats Directive.  相似文献

One of the main problems that public institutions face in the management of protected areas, such as the European Natura 2000 network, is determining how to design and implement sustainable management plans that account for the wide range of marketed and non-marketed benefits they provide to society. This paper presents an application of a stated preference valuation approach aimed at evaluating the social preferences of the population of the Basque Country, Spain, for the key attributes of a regional Natura 2000 network site. According to our results, individuals’ willingness-to-pay (WTP) is higher for attributes associated with non-use values (native tree species and biodiversity conservation) than for attributes associated with use values (agricultural development and commercial forestry). The paper concludes that management policies related to Natura 2000 network sites should account for both for the importance of non-use values and the heterogeneity of the population's preferences in order to minimize potential land use conflicts.  相似文献

Systematic conservation planning (SCP) seeks to propose new reserves through a scientifically rigorous process using databases and research selection algorithims. However, SCP exercises have been criticized for “knowing but not doing”, i.e. not implementing the proposed reserve. But there is an additional problem that can be called “knowing but not knowing”, knowing things from databases, but not knowing crucial contextual information about community-based social processes that have supported the high forest cover and biodiversity detected. Examined here is how a common property region of the Sierra Norte of Oaxaca, Mexico has maintained high forest cover in the absence of public protected areas, while multiple SCP exercises have advocated for the creation of public protected areas in communal tropical montane cloud forests and pine forests as strategies for biodiversity conservation and resilience to climate change. Methods included archival research, review of community documents, focus group interviews, semi-structured interviews, participant observation, land use transects, and GIS analysis and remote sensing. Conservation in the region originally occurred because of low population densities, steep slopes and a lack of agricultural subsidies, supported by locally adapted agricultural practices. In the 1990s, a transition from passive to active conservation took place with land use zoning plans, community conservation rules, community forestry enterprises and payments for environmental service programs that consolidated a trend towards high, unthreatened forest cover. Today, the study communities have an average of 88.3% forest cover, with 61% of that in informal conservation based on community land use zoning and rules and another 14% governed by forest management plans approved by the Mexican government. We argue that truly systematic conservation plans would seek to understand how communities in the region are already managing forests for conservation. It is pointless and uninformed to advocate for top-down conservation interventions of forests that are already robustly conserved and resilient to climate change due to community action.  相似文献

This paper reports results from a study of resource degradation and conservation behavior of peasant households in a degraded part of the Ethiopian highlands. Peasant households' choice of conservation technologies is modeled as a two-stage process: recognition of the erosion problem, and adoption and level of use of control practices. An ordinal logit model is used to explain parcel-level perception of the threat of the erosion problem and the extent of use of conservation practices. Results show the importance of perception of the threat of soil erosion, household, land and farm characteristics; perception of technology-specific attributes, and land quality differentials in shaping conservation decisions of peasants. Furthermore, where poverty is widespread and appropriate support policies are lacking, results indicate that population pressure per se is unable to encourage sustainable land use. The challenge of breaking the poverty-environment trap and initiating sustainable intensification thus require policy incentives and technologies that confer short-term benefits to the poor while conserving the resource base.  相似文献

The spatial pattern of urban development has important ecological and conservation implications. Urban sprawl, characterized by scattered and low-density urban development, is commonly criticized for its negative ecological impact. In response, growth management policies have been proposed in order to promote compact development, which is generally considered more favorable from an ecological perspective. Spatial simulations of land cover change are useful for comparing urban development scenarios and their potential effects. One aspect that has not received much attention is how the rate of development may affect differences between compact development and urban sprawl in terms of their potential impact to biodiversity conservation at the landscape scale. Our goal in this study was to compare the spatial pattern and landscape-scale conservation and ecological implications of sprawling development (expected under unregulated development) versus compact development (promoted by growth management policies) at different development rates. We focused on Israel's Mediterranean region—a region characterized by high human population density and heterogeneous land cover. Using a cellular automata model, DINAMICA-EGO, we calibrated and validated an urban development model for the period between 1998 and 2007. Using this period as a reference, we simulated two scenarios 20 years into the future: unregulated (resulting in a more sprawling development pattern) versus regulated development (resulting in a more compact development pattern). For each scenario we analyzed a range of development rates, and compared built-up area patterns, and several landscape-level attributes of natural habitats, conservation priority areas, and protected areas. We found that at development rates comparable to those observed during 1998–2007, there was no major difference between the two scenarios. At higher development rates, some differences between the scenarios emerged: natural core areas were more fragmented and smaller in their extent, and a higher proportion of conservation priority areas were expected to undergo development in the unregulated scenario. Overall, the regulated scenario was more favorable for conservation. Since the regulated and unregulated scenarios exhibited only minor differences in lower development rates, modifications to policy measures included in the regulated scenario should be considered in order improve its effectiveness.  相似文献

Dynamic models of ecosystem services supply and scenario analysis of changes in multiple services are being increasingly used to support land use planning and decision making. This approach reduces potential and real conflicts among various stakeholders potentially creating win–win solutions for all. It is particularly applicable in areas where insufficient land for agriculture and settlements is resulting in high rates of conversion of natural forest and grasslands. We quantified and mapped multiple ecosystem services, including habitat provision as a proxy for biodiversity, carbon storage and sequestration, and water balance and supply in the Sarvelat and Javaherdasht region of the globally-significant Hyrcanian (Caspian) forests in northern Iran using the Integrated Valuation of Ecosystem Services and Tradeoffs tool. This region is experiencing a rapidly increasing rate of forest conversion and as a result, the protected area located within the study landscape is threatened by human encroachment. Plausible future landscapes were modeled under three scenarios: (i) business as usual; (ii) protection-based zoning which reflects an expansion of the protected area boundary to prevent land use changes; and (iii) collaborative zoning through redefining the protection boundary simultaneously with an adjustment to meet local stakeholders’ objective of expansion of anthropogenic cover. The results showed that the collaborative zoning scenario would best contribute to effective policy because it presents a more rational spatial configuration of the landscape maintaining the provision of ecosystem services. This scenario may lead to reduced environmental impacts while achieving less conflict between the government and local communities. These results will help to inform and shape natural resource management policies in Iran and is applicable elsewhere in the world.  相似文献

Increasing pressure on extensive farming systems in marginal areas requires them to become more resilient and adaptable to extreme conditions brought about by climate change. Yet these rangeland areas must also be protected as refuges for biodiversity and as important carbon stores. Recent United Kingdom policy initiatives are encouraging the use of traditional or native breeds of livestock to preserve genetic diversity, due to their perceived adaption to harsh environments and their value for managing extensive habitats for conservation. It is not clear however, whether these benefits are based on scientific evidence or perhaps more on current opinion; nor whether farm system practices are likely to change in response to these initiatives. This study offers an approach that can support future empirical studies designed to better inform such policy decisions.A survey was carried out to provide insight into current opinions regarding the impacts of cattle on hill environments and the cattle breeds appropriate for hill environments, before more detailed farm interviews provided data for a characterisation of suckler beef farming systems in Scotland using a typological approach. Survey results indicated that the majority of respondents believed cattle have a positive effect on hill environments when carefully managed, yet there was wide diversity in opinion regarding the type of impacts and most suitable breeds. Interview results highlighted the diversity of management systems, decision making processes and cattle types present and indicated significant variation in farmers’ views regarding breed hardiness, suitability and reasons for their choice of breed. Three system groups: Traditionalists, Improvers and Production optimisers, were clearly defined by the typology, with significant variation observed in their management practices and views. This study suggests that hill beef farmers appear to not only adapt their production systems according to their current bio-physical and financial circumstances, but also from personal experience. Accumulation of this kind of evidence is long overdue and could provide support to the development of any future policies regarding cattle and hill environments.  相似文献

Forest management poses particular challenges as the pressure on forests is huge due to deforestation. In this context, the establishment of protected areas is a common conservation measure where institutions are put in place and sanctions regarding forest use are enforced. This paper focuses on the practice of sustainable forest management and the associated perspectives of local institutions at the rainforest margins of Lore Lindu National Park (LLNP) in Central Sulawesi, Indonesia.  相似文献

Strict regulations, such as the EU Nature Directives, remain pivotal for halting the downward spiral for some protected species. In recent years, though, it has become clear that nature protection rules, are also generating perverse incentives, especially when rigidly applied to areas that have already been transformed by human use, such as agricultural land, quarries and port sites. With the arrival of novel incentive concepts, such as temporary nature in several EU Member States, an unprecedented window of opportunity exists to reframe current nature protection rules. Temporary nature fosters private landowners, ranchers and project developers to actively participate in the recovery of endangered species, also in urban and industrial environments. In return for allowing nature to develop on their undeveloped and vacant lands, the project developers are provided with the legal guarantee that they can still subsequently develop their lands at a later stage. These newly founded conservation policies, which are increasingly endorsed by stand out as striking illustrations of the recently emerged branch of reconciliation ecology, since they aim at increasing biodiversity by opting for win-win scenarios in human-dominated landscapes. It is concluded that a more reconciliatory approach towards nature conservation, which goes beyond the ambit of protected areas, can serve as a catalyst for biodiversity recovery across the wider landscape. Further research will need to underpin whether the ambitious presumptions with regard to these well-intentioned and innovative approaches to nature conservation are justified.  相似文献

The principle of “Free, Prior and Informed Consent” (FPIC) is promoted through international agreements and safeguards in order to strengthen social equity in resource management by requiring consent from indigenous and/or local communities prior to actions that affect their land and resource rights. Based on early experiences with implementing FPIC standards in mining and forestry, we examine how FPIC has impacted social equity and why. In both sectors FPIC was first operationalized through non-governmental standards that revealed ambiguities surrounding its definition and implementation. In mining, FPIC was first codified in the standards of financial investors, while in forestry FPIC emerged within competing market-based certification schemes, resulting in contrasting definitions. In both sectors, contextual factors such as government laws and policies, the socio-political environment and the overall distribution of rights and resources strongly shape the impacts of FPIC on equity particularly for actors without strong legal rights. These findings are significant for emerging arenas such as REDD+, where there is much debate around the role of governments, financial institutions and market-based actors in applying FPIC for social equity outcomes.  相似文献

In Thailand, land use planning and policy decision-making were—and to some extent still are—organized in a hierarchical and disjointed fashion. This is also true for the utilization of public lands, including forest reserves in the northern uplands that are often settled by ethnic minorities. There are, however, instances of change in land policies and regulations and in the way decisions and plans are made. Doi Mae Salong (DMS) in Northern Thailand, where there is a trend towards land use for conservation purposes, is a case in point. This paper aims to explore decision-making by farmers in DMS in the context of changing land regulations and policies from the 1950s to the present. The Institutional Analysis and Development (IAD) framework, together with a historical perspective and with narratives on land management through time, were applied by using in-depth interviews of key informants and group farmers’ discussions as tools. The time period under investigation was divided into three periods of change: The first period, before the year 1960, was an era of security concern. In contrast, the second period, from 1961 to 1996, was an era of emerging conservation priorities. Finally, the third period, from 1997 to the present, is an era of lessons learned from the conservation era. Land use decision outcomes reveal that the decision-making processes of farmers are influenced both by the hierarchical decisions of higher authorities and by horizontal linkages among multiple stakeholders. However, while farmers participate readily in forest conservation activities, they do not play an active role in the process of changing policies.  相似文献

This paper describes the economic policies that have transformed the pastoral sector in post-socialist Mongolia, and their impact on pastoral land use. These policies reflect the influence of development economists from the Asian Development Bank who have been advising the Mongolian government, and their conviction that exclusive private rights to land are a necessary precondition of an efficient rural market economy. These assumptions stand in marked contrast to indigenous Mongolian conceptions of rights over land, and the policy debate reflects the contested nature of knowledge of the Mongolian environment. However, far from preventing damage to the resource base, evidence suggests that these policies of land allocations may actually be exacerbating problems of pasture degradation. This paper argues that policies of this kind reveal a misunderstanding of the nature of Mongolian pastoralism and the conditions that have made it viable in the past. Although international development agencies lionize a romanticized notion of Mongolian “traditions” as reflecting a “respect for nature”, there is little appreciation of the actual institutions that successfully conducted pastoralism until recently, the concrete embodiment of Mongolian pastoral knowledge. Environmentalist agendas reflect a familiar western interest in promoting western conservationist ideology and establishing and expanding protected areas to harbour wildlife and biodiversity. Mongolian practices tend to be cast as “traditions” to be utilized for the greater goal of conservation as conceived of in western terms, rather than seen as part of wider social and political institutions of land use.  相似文献

Considerable proportions of the remaining global forest areas are currently harboured in tropical countries. Reducing deforestation in this region is important to help mitigate climate change. Effective forest conservation approach is needed to reduce deforestation and degradation in these countries. Here, we investigated the forest conservation effect of community forests and protected areas using country scale data in Cambodia. In addition to these two forest conservation approaches, we also evaluated the effectiveness of protected forests, which are similar to protected areas but managed by different authorities. We compared deforestation between 2006 and 2016 in areas under the three forest conservation approaches and a non-conserved area by applying the inverse probability of treatment weighting with the propensity score minimizing confounding effects. The results showed that community forest, protected areas, and protected forest significantly decreased deforestation compared with non-conserved forests. Out of the three forest conservation approaches, protected forest was the most effective and community forest was the least effective. We conclude that all of the policies we evaluated are effective for forest conservation but the effectiveness varies depending on the approach. Our findings also suggest that the authority managing the given approach plays an important part in its effectiveness.  相似文献

Successful land claims on protected areas by previously disenfranchised communities often result in co-management agreements between claimant communities and state conservation agencies. South Africa, in particular, has pursued co-management as the desired outcome of land claims on its protected areas. We review four cases of co-management on protected areas in South Africa, and reflect on the appropriateness of the pursuit of co-management as the preferred outcome of land claims. Despite promises of pro-poor, democratically informed management, the practical experience of co-management has seen the continuation of the status quo in terms of conservation, with very few material benefits for claimant communities and limited sharing of responsibilities and decision-making functions. The findings underscore two deep challenges facing co-management in cases of land claims worldwide. First, during land claims negotiations in cases involving protected areas, the state cannot be expected to represent the best interests of its citizens (the land claimants), while simultaneously seeking to meet national and international obligations for protected area coverage. Second, the concept of democratic co-management may sit uncomfortably beside the realities of managing loss-making protected areas with ever-shrinking conservation budgets. Where co-management agreements have already been signed, ensuring that new landowners do indeed have a say in management should form the driving focus for co-management practice going forward.  相似文献

This paper highlights the limiting factors of agricultural production in Zimbabwe and presents conservation agriculture (CA) as a potential solution to address many of these challenges. CA, based on the three principles of minimum soil disturbance, crop residue retention and crop rotations, targets low soil fertility, moisture deficits and low management standards through the use of soil-fertility-enhancing technologies (precision fertilizer application, crop rotations, sequencing and interactions), improved moisture use efficiency and higher standards of agronomic management practices. The paper also explains the role of CA in natural resource conservation as increasing productivity will reduce the land under crop production and increase the area under natural vegetation. Trends in the development of CA in the past five years and its current status in the country are explained, with the roles of different stakeholders outlined. Evidence on the impact of CA on both food security and the environment is presented. In conclusion, the paper looks at the various factors that may affect the spread of CA to different agro-ecological zones in the country.  相似文献
