The Government of Indonesia has published a number of policies and regulations to better manage its vast amount of tropical peatland, yet the degradation and conversion of Indonesian peatlands still continues. This paper analyses the institutional fit between Indonesian regulations related to peatland use and the characteristics of peatland users. We reviewed Indonesian legal policies and regulations on peatland use and management and conducted questionnaires and interviews with peatland users and policy makers in order to understand their practices and incentives in relation to the implementation of the four main peatland regulations. We focus on two provinces with large peatland areas: Jambi and Central Kalimantan. Using a framework for assessing the degrees of fit between the rule creators and adopters for peatland management, this paper shows that the degree of technical, political, and cultural fit of Indonesian peatland regulations can be classified as low to moderate. The paper shows that many peatland users are insufficiently aware of peatland regulations. The lack of socialisation on the contents of the regulations and the alternatives for peatland best practices, together with the lack of field monitoring and law enforcement are the important causes of non-compliance with peatland regulations. However, there are ongoing processes of fitting visible that are largely driven by the local government and NGOs. We discuss the degrees of fit and present some lessons for increasing the degree of fit for peatland regulations.  相似文献

To restore China's degraded environment, the government launched an environmental restoration project named the “Grain for Green” Project (GGP) in 1999. From 1999 to 2010, the government will spend US$ 40 billion to convert 147 million ha of farmland into forest and grassland and 173 million ha of wasteland (including abandoned farmland) into forest in 25 provinces. A primary focus is to replace farming and livestock grazing in fragile areas with reforestation and planting of forage crops. Given the project's tremendous size and number of participants, the attitudes of the affected farmers will strongly influence the GGP's success. To learn their attitudes, we surveyed 2000 farmers in 2005 to quantify their opinions of the GGP and how it has affected their livelihoods, and we discuss the concerns raised by these attitudes. Farmers appreciated the grain and financial compensation offered by the GGP, but few considered planting of trees (8.9%) or forage species (2.2%) to be a priority. Although only 19.1% felt that their livelihoods had been adversely affected by the GGP and 63.8% supported the project, a large proportion (37.2%) planned to return to cultivating forested areas and grassland once the project's subsidies end in 2018. Therefore, much of the restored vegetation risks being converted into farmland and rangeland again, compromising the sustainability of the environmental achievements. To succeed, strategies such as the GGP must compensate farmers fairly for their costs, create new agricultural products and techniques for use on more suitable land, and create job and training programs that account for the needs and desires of farmers and give them alternatives to returning to old land-use practices.  相似文献

Reservoirs for the transient storage of water in order to lower river flood peaks would usually be built on farmland and used in case of a serious flood event. Farmers’ willingness to have their lands included in a reservoir critically depends on the compensation they will obtain. Our paper proposes a new compensation scheme that consists of an unconditional annual payment and a reparation payment conditional on flooding. We determine the properties of an optimal contract offered by the river authorities to farmers that specifies the compensation scheme and the rules for the use of the reservoir. The two-tier payment scheme induces crop choices of farmers that lower the damage profile of land use and it covers the long-term costs of land use change to ensure voluntary participation. We illustrate the working of the payment scheme using data from a case study from the river Tisza in Hungary.  相似文献

In this study, an interval fuzzy chance-constrained land-use allocation (IFCC-LUA) model is developed for sustainable urban land-use planning management and land use policy analysis under uncertainty. This method is based on an integration of interval parameter programming (IPP), fuzzy flexible linear programming (FFLP) and chance-constrained programming (CCP) techniques. Complexities in land-use planning management system can be systematically reflected, thus applicability of the modeling process can be highly enhanced. The developed method is applied to planning land-use allocation practice in Nanjing city, China. The objective of the IFCC-LUA is maximizing net benefit from LUA system and the main constraints include investment constraints, land suitability constraints, water/power consumption constraints and wastewater/solid waste capacity constraints. Modeling results indicate that desired system benefit will be between [1.34, 1.74] × 1012 yuan under the minimum violating probabilities; the optimized areas of commercial land, industrial land, agricultural land, transportation land, residential land, water land, green land, landfill land and unused land will be [290, 393] hm2, [176, 238] hm2, [3245, 4390] hm2, [126, 170] hm2, [49, 66] hm2, [1241, 1679] hm2, [102, 138] hm2, [7, 10] hm2 and [178, 241] hm2. They can be used for generating decision alternatives and thus help decision makers identify desired land use policies under various system-reliability constraints of economic development requirement and environmental capacity of pollutant. Tradeoffs between system benefits and constraint violation risks can also be tackled.  相似文献

The siting of both onshore and offshore wind farms has caused controversy in a number of countries, particularly in Europe, which currently has the world’s largest array of offshore wind turbines. Like the rest of the world there has been a dramatic increase in wind farm development In Australia over the last two decades but none of this has occurred in the offshore environment. Australian wind farms are predominantly located onshore around the southern part of the continent where wind energy is high. This has specifically affected rural coasts where it has created planning and land use policy issues along with environmental impacts and associated public and political reaction. This paper examines the geographic spread, timing and concentration of Australian wind farms around the coast. It also examines the extent to which scientific knowledge on wind farm impacts is incorporated into different state and federal land use and environmental policy and legislative frameworks. The paper concludes that the rapidity in the expansion of the Australian wind energy sector has outpaced strategic land use planning resulting in a piece-meal and cumulative wind farm development on rural coasts.  相似文献

In Brazil, the Forest Code requires landholders to maintain fixed-width buffers of native vegetation along watercourses – legally called Areas of Permanent Preservation (APPs). In 2012, agricultural activities started to be partially allowed in APPs, but only if best management practices on soil and water conservation are adopted and if a narrow buffer strip with native vegetation is restored adjacently to the watercourse. In this paper, we present a modeling framework to investigate the capacity of legal compliant APPs to supply watershed services (erosion control and stream bank stabilization) in a 2,200 ha watershed in São Paulo State, Brazil. Our results suggest that the narrower the riparian buffer the lower the control of soil erosion dynamic within APPs, and that riparian buffers smaller than 8 m can act as a source of sediments to streams. The adoption of best management practices can contribute to controlling soil erosion within APPs but the presence of native forests in the first 15 m is necessary to guarantee equivalent protection to streams when compared to APPs completely covered by forests. Moreover, we observed that forest restoration within APPs helped to reduce the average soil loss of the watershed by only 20 %, compared to a reduction of 55 % when best practices are implemented in all watershed agricultural areas. We conclude that (i) the reduced requirements for APP restoration may contribute to stream sedimentation, which will likely affect the supply of watershed services by stream ecosystems; (ii) the implementation of best management practices in APPs will not have the same effect as native forests to reduce stream sedimentation; and (iii) the adoption of best management practices in all agricultural production areas – and not only within APPs as required by law – is the best strategy to promote the supply of watershed services to society.  相似文献

The rural–urban interface is the place of transition between that which we call “urban” and that which we call “rural.” The interface is situated between two places perceived to be different, but which are indelibly linked. Although the functional differences between “rural” and “urban” people (or those seen as “been-heres” versus “come-heres”) seem to be diminishing, differing perspectives and preferences persist along the rural–urban edge. Such differences influence the way that land users, decision makers, and the community manage the environment and react to landscape change. Using a comparative case study in Calaveras County, California, I examine the differences and similarities between “been-heres” and “come-heres” along several lines: basic demographic characteristics, political party affiliations and ideologies, and conceptions of private property rights, concluding that the dichotomy is false but instructive. The been-here/come-here divide, rather than being a definitive means for characterizing stakeholders or predicting their behavior or perspectives, serves as a heuristic for understanding the starting places of certain actors. Furthermore, this kind of analysis reveals not only where and how people and perspectives contrast but also the ways that they converge. Improving our understandings differing people and perspectives is especially important as decision-makers struggle to plan for and manage livable places and sustainable environments among groups with varying preferences which may sometimes conflict.  相似文献

This paper investigates the transposition and implementation of the Habitats Directive in four European member states, namely Denmark, the Netherlands, Greece, and Romania, and the role that institutional misfits have played in more or less successful implementation processes. Departing in the ‘Worlds of Compliance’ literature, it also explores if this typology can be useful for understanding the ways member states address institutional adaptation pressures in the implementation steps following the transposition phase. The requirements in the Habitats Directive expanded most member states’ nature conservation frameworks, especially in the obligation to introduce pro-active conservation, and it also laid down a number of steps to be taken for creating the European Natura 2000 network. It was found that the transposition did mostly follow general compliance types, but that these types also helped understand the extent and adequacy of adaptations and changes to the institutional framework in the implementation processes following the directive’s adoption. Implementation challenges were different for different countries. They showed a need to align institutional frameworks for a) Natura 2000 in areas with several existing types of landscape protections and ensuing spatial and institutional overlaps; b) clarifying the roles and responsibilities of various authorities involved in implementation; c) ensuring coordination with the other sectorial policy areas that interact with the Habitats Directive (such as the Nitrate Directive and the Water Framework Directive). It turned out that there could be a need for more flexible and less-top-down European legislation, providing a larger room-for-manoeuvre for integration with domestic approaches.  相似文献

This paper quantitatively analyses the cost‐effectiveness of alternative green payment policies designed to achieve a targeted level of pollution control by heterogeneous microunits. These green payment policies include cost‐share subsidies that share the fixed costs of adoption of a conservation technology and/or input reduction subsidies to reduce the use of a polluting input. The paper shows that unlike a pollution tax that achieves abatement through three mechanisms, a negative extensive margin effect, a negative intensive margin effect and a technology switching effect, a cost‐share subsidy and an input reduction subsidy are much more restricted in the types of incentives they provide for conservation of polluting inputs and adoption of a conservation technology to control pollution. Moreover, they may lead to varying levels of expansion of land under production. Costs of abatement with alternative policies and implications for production and government payments are compared using a simulation model for controlling drainage from irrigated cotton production in California, with drip irrigation as a conservation technology.  相似文献

Military Training Areas (MTAs) cover an estimated 200–250 million hectares globally, occur in all major ecosystems, and are potentially significant conservation assets. In some jurisdictions, MTAs may be the largest terrestrial land use category that is owned and operated by a sovereign government. Despite this, MTAs are not recognised as either a conservation or environment protection resource. Further, no MTAs are managed for their environmental values, defined as aspects of the environment that are valued by society, nor is there any specific MTA management guidance that details how both the military training and environmental values of a MTA can be maintained.We conducted a desktop review of Australian and German MTA management documentation to determine whether they contained management principles that recognised both military training and environmental values. Management documentation from these two countries was chosen as they are considered to be among countries at the forefront of MTA management globally. Our review determined that both the Australian and German management regimes do not have specific management principles for these values. This is likely to be the case for the majority of MTAs globally.For the first time, we develop MTA management principles that integrate the management of both military training objectives and environmental values. Key to achieving this integration is an understanding of the intersection of the impacts of military training on the environment, and the known, or potential, environmental values of a particular training area.To assist with the implementation of the management principles, we developed a new conceptual framework for the management of MTAs. The framework contains two adaptive management loops. The first focuses on the management of environmental values of MTAs, the second targets the military training values of MTAs. These two management loops facilitate for the development of management practices that optimise MTA management for both military training and biodiversity conservation.  相似文献

Farming has been the basis to work, culture and social forces for millennia. It still dominates the lives of most of the world's poorer people, but in post-industrial western countries agriculture's contribution to national economies is now minor. Nevertheless, most OECD countries’ agricultural policies are aimed at maintaining the size of this sector even where this conflicts with its economic significance or adversely affects the environment. Australia has a first world economy, but a third world export profile, with 20% of its export value derived from agriculture. Although it is efficient in agricultural man-power, this sector consumes 70% of the water and 60% of the land resources of the continent to produce food for an estimated 55 million people. Agricultural policies maintain the productivity of the sector, but are ineffective in stemming the associated environmental degradation, biodiversity loss and rural population decline. As in other post-industrial societies, Australia needs to re-define what its agriculture sector represents, environmentally and socially. This will require greater reappraisal of property rights, public and private benefits and legal structures supporting both. More effective alternative policies are needed for large tracts of unproductive farmland where environmental and social decline are endemic. This paper explores alternative options that offer more balanced prospects in the face of current paradoxes, including paying farmers directly for stewardship services, providing better incentives for retiring non-productive areas from agricultural land use, and retiring watersheds, streamlines and other areas of essential environmental function from agricultural production for better biodiversity conservation.  相似文献

The planting of riparian margins is a policy option for pastoral farmers in response to land use induced environmental issues such as declining water quality, stream bank erosion, and loss of aquatic and terrestrial habitat. We elicited the views and experiences as to pros and cons of planting riparian margins from two sets of dairy farmers from Taranaki, New Zealand: those who are or have planted riparian margins, and those who have not yet done so. Those farmers who have planted riparian margins identified 21 positive aspects of riparian margin plantings and 11 negative aspects of riparian margin plantings. Perceived benefits identified by this group include water quality, increased biodiversity, the provision of cultural ecosystem services, immediate direct benefits to farm management and the farm system, and in some instances increased productivity on-farm. In contrast, those farmers that had fenced but not planted their riparian margins did not consider that riparian margin plantings could add further benefits to that which could be achieved by excluding stock from waterways, and associated only negative perceptions with riparian margin plantings. Planting riparian margins is not cost neutral and will not deliver anticipated environmental benefits in every situation. However, we argue that riparian margin plantings are an important ecological infrastructure investment that needs to be captured within a wider policy framework, the benefits of which extend beyond the mitigation of a single negative externality generated by land use practices, such as nutrient loss, and contribute to a multifunctional landscape.  相似文献

The 1990s saw two different and even contradictory trends in Israel. On the one hand, there was a substantial increase in environmental awareness, on the part of both the general public and decision-makers, that led to a change in the land use planning policy at the national level. On the other hand, the Israel Lands Council (ILC), the body empowered by law to shape the national land policy, made a series of decisions that severely violated the principle of preserving agricultural land and led to massive conversion of agricultural land and open space for commercial, industrial, and residential development. Thus the national land policy became incompatible with the land use planning policy and the rise in environmental awareness it reflected.  相似文献

Canada's agricultural business risk management (BRM) programs require significant public expenditure, with unclear consequences related to climate change adaptation and mitigation through the adoption of beneficial management practices (BMPs). This study examines the relationship between Canada's current suite of BRM programs and the adoption of practices that mitigate GHG emissions in crop agriculture. We review the impacts of agricultural insurance on climate adaptation and mitigation, identifying impacts on both the intensive and extensive margins of production. We consider five potential program modifications, including: (1) changes in producer insurance premiums in AgriInsurance for the adoption of practices that would decrease the actuarially fair insurance rate if they were properly incorporated in the calculation; (2) dedicated insurance products related to trials of specific BMPs; (3) adjustments to current programs to allow more whole-farm considerations and intercropping; (4) cross-compliance measures on AgriInvest tied to environmental education; and (5) reduced insurance coverage for unfavorable environmental practices. While the effects of these potential modifications remain uncertain, they will drive the data collection process necessary to ensure that Canada's BRM programs play an appropriate role in greenhouse-gas reducing BMP adoption and climate change adaptation and mitigation.  相似文献

Riparian landscapes are natural habitats of unique ecological, environmental and scenic values, which are highly sensitive to human intervention and impact. Yet, due to their qualities, and especially the presence of water, they are also usually attractive for recreation purposes. This is more so in arid and semi-arid zones like Israel. Nevertheless, in the past, the importance of riparian landscapes in Israel did not receive adequate attention in policy and planning. As a result, over the years they were exposed to various negative impacts, including pollution by industrial and agricultural effluents, diversion of water for agricultural and other purposes, and land use conflicts. Although in recent years, with the growing awareness of their ecological and recreational potential, considerable efforts are being invested in the rehabilitation of deteriorated riparian landscapes, their protection is still deficient.This article reviews and examines policy tools used for the protection of riparian landscapes in Israel, focusing on legislation, institutional structure and physical planning as they emerge from relevant laws, reports and literature. It reveals, among others, gaps and deficiencies in legislation, institutional dualities along with split authorities both expressing a particularistic approach, and, until recently, lack of relevant designated planning. The article concludes by offering some suggestions for improving the protection of riparian landscapes in Israel, including: integration of existing laws based on a whole watershed approach; reorganization of institutional structure to facilitate a national vision of riparian landscapes rather than the existing particularistic approach; formulation of structured planning procedures to ensure the realization of designated national plans; and promotion of awareness to riparian values at various levels.  相似文献

As urban areas continue to expand, the need to consider nature conservation objectives in planning is growing. Policy makers across Europe recognize that effective nature conservation requires an integrated approach to land use planning that includes relevant ecological and spatial knowledge. Although a number of such integrated approaches have been developed, many local authorities in Europe encounter important institutional barriers to this integration. This is particularly true for countries in Central and Eastern Europe (CEE) like Bulgaria. The post-socialist transformation in Bulgaria led to intensified urban growth and local authorities struggle to find a balance between environmental and socio-economic interests. Meanwhile, the Environmental Policy Integration ‘principle’ (EPI) has been gaining prominence in Europe, aiming to address the trade-offs between environmental and economic incentives. Research highlights that successful EPI depends on institutional processes within different economic sectors and across governmental scales. These processes have not yet been comprehensively studied in the CEE and in Bulgaria. This article assesses the EPI process in urban planning in Bulgaria and identifies the institutional approaches that may contribute best to EPI in urban planning. Using the example of the “Corner Land” project in the city of Burgas, we discuss the key challenges that the local authorities face in addressing nature conservation in land use plans. The findings indicate that EPI is to a high degree constrained by the lack of an efficient communicative process across fragmented organizational structures throughout the entire planning process. While a procedural approach to EPI appears to be prevalent it is concluded that a communicative approach is urgently needed if the sustainability of urban plans is to be safeguarded and negative impacts on nature prevented.  相似文献
