The implementation of the National Biodiversity Strategies and Actions Plans (NBSAP), as required by Article 6 of the UN Convention on Biological Diversity (CBD), would improve the base for political decisions by quantifying the costs and benefits of biodiversity conservation in monetary terms and by illustrating the benefits of related ecosystem services (ESS). However, so far the costs and benefits of the NBSAP have not been routinely estimated. This paper presents results from research quantifying the financial costs and benefits of implementing a set of measures based on the National Strategy on Biological Diversity in Germany (NBS). Based on the NBS and the Quality Status Reports of the EU Habitat Directive, a conservation program was developed consisting of land use changes for six ecosystems/land use types: forests, arable land, grassland, peatlands, wetlands and dry habitats. In addition to the benefits of maintaining biodiversity, two potential ESS benefits of the NBS, water purification and climate mitigation, are estimated as well as the financial costs of implementation. A nationwide contingent valuation study was undertaken to determine the benefits of maintaining biodiversity as a result of the conservation program. The benefits of the conservation program with regard to the ESS water purification are calculated for N-reduction in the leachate and based on abatement costs. The contribution of nature conservation to climate mitigation is calculated for the avoidance of greenhouse gas (GHG) emissions and based on damage costs. The results of the study indicate that the implementation of the NBS would lead to significant financial costs, but the benefits would exceed the financial costs of measures.  相似文献

Effective protection of biodiversity in areas of high conservation value requires trade-offs between local use of natural resources and conservation restrictions. The compromise is often difficult to reach, which causes conflicts over the management priorities of existing and potential protected areas. Ecosystem services (ES) perspective offers a promising avenue for diagnosing and reconciling contrasting interests concerning the use of benefits from ecosystems. We examined how the spatial proximity to the Białowieża Forest (BF), a European biodiversity hotspot, affects the perceived use of ES by local communities. We performed a survey among 719 respondents from 35 villages situated within BF and in its vicinity. We found that both the declared use of ES and the perceived influence of ES on household’s economy was declining with the distance from BF with particularly high differences between areas not further than 3 km from BF and areas located 3-15 km from BF. Different zones varied in terms of benefits from tourism and costs connected with a potential limited access to ES due to conservation. Broadening the perspective, we argue that the trade-offs linked to ES may vary depending on the location in relation to the protected area and that local communities should not be treated as a homogenous group when considering benefits from the forest. Awareness of common patterns of ES use over space and local specificity may enhance effective management of even highly contested conservation areas.  相似文献

Commodity levies are used increasingly to fund producer collective goods such as research and promotion. In the present paper we examine theoretical relationships between producer and national benefits from levy-funded research, and consider the implications for the appropriate rates of matching government grants, applied with a view to achieving a closer match between producer and national interests. In many cases the producer and national optima coincide. First, regardless of the form of the supply shift, when product demand is perfectly elastic, or all the product is exported, domestic benefits and costs of levy-funded research all go to producers and they have appropriate incentives. Second, if research causes a parallel supply shift, the producer share of research benefits is the same as their share of costs of a levy, and their incentives are compatible with national interests. In such cases, a matching grant would cause an over-investment in research from a national perspective. However, if demand is less than perfectly elastic, and research causes a pivotal supply shift, the producer share of benefits is smaller than their share of costs of the levy, and they will under-invest in research from a national point of view. A matching grant can be justified in such cases, however the magnitude of the optimal grant is sensitive to market conditions.  相似文献

This paper estimates the benefits and costs of soil conservation in the Upper Mahaweli Watershed of Sir Lanka. The costs of soil erosion control include the implementation costs of control measures, while the benefits are reductions in the costs of soil erosion. In contrast to many studies in developed countries, the on‐site benefit of soil erosion control in Sri Lanka is estimated to be greater than the off‐site benefit While a social benefit‐cost analysis demonstrates that it is socially desirable to implement conservation measures, the private financial analyses indicate that it is feasible for individual farmers to adopt the conservation measures. Despite private economic feasibility, programs addressing farmers' reluctance to adopt soil conservation measures may be preferable to public intervention in soil conservation activities when the on‐site benefits are greater than the off‐site benefits.  相似文献

This paper develops a GIS-based modeling framework that integrates a farm model, a hydrologic model, and a soil organic matter model to examine spatial targeting of conservation tillage to jointly improve water quality and carbon retention benefits in agricultural watersheds. Previous studies have examined the targeting of conservation tillage, land retirement, and riparian buffers at watershed scale to achieve water quality benefits but not considered carbon retention benefits. An empirical application of the framework in the Fairchild Creek watershed in Ontario shows that targeting conservation tillage based on sediment abatement goal can also achieve comparable carbon retention benefits in terms of percentage reduction of its base carbon losses. The targeted subcatchments for conservation tillage vary across the watershed based on benefit to cost ratios. The pattern of conservation tillage targeted based on carbon retention goal is similar to that with a sediment abatement goal but slight differences are found because of different carbon content in the soils. The modeling results have important policy implications for the design of conservation stewardship programs such as setting sediment abatement goal as an indicator to achieve joint environmental benefits and direct public fund to locations that can achieve environmental goals at least costs.  相似文献

Local conservation efforts are often related to benefits at higher governmental levels. On the one hand, these efforts are strongly connected to local land-use decisions. On the other hand, activities such as sustainable water management or biodiversity conservation are associated with regional, national or even global public goods. Therefore, spatial externalities or spillovers exist, which—if not adequately compensated for—lead to an underprovision of the public goods and services concerned. This article investigates intergovernmental fiscal transfers as an innovative instrument for compensating local jurisdictions for the ecological goods and services they provide across local boundaries. From a public finance perspective, fiscal transfers are a suitable instrument for internalising spatial externalities. However, most federal states use this instrument predominantly for social and economic public sector functions rather than for ecological ones. This article investigates the case of the ecological “ICMS” that was first introduced by a few states in Brazil during the 1990s. Part of the revenue from this value-added tax is redistributed to the local level on the basis of ecological indicators. In this way, the state level uses fiscal transfers to compensate municipalities for the existence of protected areas and other ecological services provided within their territories. The Brazilian experience illustrates that such fiscal transfers can represent both a compensation for land-use restrictions and an incentive to value and engage in more conservation activities at the local level.  相似文献

Community forestry can deliver economic, socio-cultural, and ecological benefits to rural communities, yet criticisms have arisen that community forestry remains dominated by the decision-making of offsite experts and management techniques inappropriate for some communities. We use a case study approach to ascertain the needs, wants, and current realities of selected forest communities in Brazil and Mexico, to inform bottom-up approaches to community interventions. In identifying community-defined goals, we found that other livelihood strategies, particularly agricultural practices, need to be better integrated in the planning of forestry interventions overly focused on timber production. Site-specific intervention models need to take into account the variety of contexts and community interests, rather than replicating models that have been successful in other jurisdictions. A better understanding of local perspectives can aid in the design of community forestry interventions brought by conservation and development agencies, by adding an important and under-studied perspective to the problems that face community forestry.  相似文献

Biodiversity loss is a serious and ongoing global environmental problem. Economic instruments in biodiversity policies can contribute towards reconciling the conservation costs encountered at local level with the benefits of biodiversity conservation at higher levels of governance, from regional and national levels up to the global level. This paper outlines the theoretical foundations of fiscal transfers in conservation policies and also offers a concise account of existing international experience and future prospects. The recently amended Portuguese Local Finances Law (LFL) of 2007, with its groundbreaking new article on the promotion of local sustainability, is analysed in terms of the significance of fiscal transfers for municipal budgets. It is compared with its predecessor law, highlighting changes in fiscal revenues for selected municipalities in the country in relation to their designated conservation areas. The analysis shows that these ecological fiscal transfers can be significant for those municipalities with a large proportion of land under protected status. However, because it also introduces a considerable number of changes to the Portuguese fiscal transfer scheme, the ecological impact of the new LFL is difficult to grasp due to the presence of several crossover effects. The results obtained offer significant insights both for improving the Portuguese LFL and for designing new ecological fiscal transfer schemes.  相似文献

Producers' and consumers' risk perceptions and preferences can affect perceived costs and benefits of agricultural water quality protection. Many studies find that integrated pest management actually reduces economic risks to farmers. Results from crop rotation and conservation tillage studies are mixed, while nutrient management studies indicate a potential for higher risk compared with conventional practices. Uncertainty about pollution damages to water resources is likely also to increase the perceived benefits of a given quantity of water quality protection practices. Public policies to reduce uncertainty about the costs and benefits of water quality protection practices may produce net social benefits.  相似文献

Research on environmental governance in China has shown that centre–local relations often influence the implementation and efficacy of environmental regulations. By examining changes in resource allocation and rural development between 1982 and 2005 in the region worst affected by desertification in China—the Minqin oasis in Gansu—we argue that changes in macro‐level fiscal and commodity grain policies contributed to severe regional disparity and a reduction in local state capacity in hinterland China. Intergovernmental competition over fiscal revenue encouraged cash cropping and land reclamation, and the continuous decline of the oasis ecology further reduced legitimacy in rural governance. These institutional and ecological constraints shaped the behaviour of grassroots cadres and formed the conflicting interests of the state in resource distribution and environmental conservation that continued to exist until the implementation of a centralized conservation program in 2006. The data came from 157 interviews and 628 policy documents from local archives in Gansu.  相似文献

In view of the urgent need to improve agroecosystem sustainability, several efforts have been made to evaluate the effect of alternative strategies on key environmental and socioeconomic variables at the farm, community and regional levels. Most peasant farmers manage complex and diverse agroecosystems, and constantly adapt management strategies with multiple aims. A sustainability evaluation framework for peasant systems has been applied in over 40 case studies in Latin America, from which 15 were analysed, focusing on the choice of indicators, the effect of alternative strategies on agroecosystem sustainability and the trade-offs involved. Common indicators include yields, income, agrodiversity and external input dependence. Alternative strategies include crop/product diversification and soil conservation practices. Yields, income and agrodiversity improved in most cases, but in some cases the establishment costs increased external input use. Trade-offs observed include improved performance of a subsystem (i.e. crops) vs. decreased one in others (livestock, forestry) and increases in productivity vs. decreases in stability, resilience and reliability. The difficulty of assessing systems in transition towards alternative management was acknowledged by some evaluation teams. Applying the framework to such a variety of cases allowed making the sustainability concept operational, promoted alternative strategies and generated knowledge on agroecosystem processes among stakeholders.  相似文献

We examine landowners’ conservation motives, conservation costs and information rents in environmental bidding systems designed for forestry with the help of Faustmann and Hartman models and data from Finnish conservation program. We show that the Faustmann landowners receive information rents, on average 55% of the rental payments. For the Hartman landowners the high conservation costs of old stands result in low information rents; they are only 13% of the rental payments. This estimate omits amenity benefits the landowners derive from their forests; accounting for these benefits would increase information rents dramatically. Despite the high information rents, landowners’ conservation motives decrease the rental payment required for participation in the conservation program. Hence, landowners’ conservation motives give governments a great opportunity to allocate conservation contracts in a more cost effective way, thereby extracting larger benefits for scarce conservation funds.  相似文献

The current study seeks to assess the private benefits associated with multiple soil conservation practices (MSCPs) by estimating the marginal value of crop production that can be attributed to such practices. In areas where land degradation associated with soil erosion causes serious agri-environmental challenges such as loss of soil fertility, siltation and eutrophication, a multiple approach to soil conservation is neccessary. However, notwithstanding efforts to encourage adoption of such practices, their uptake remains generally low. Analysing the effect of MSCPs on crop productivity is one of the ways through which the incentives for soil conservation can be explored. To achieve the stated objective, the current study applied propensity score matching and exogenous switching regression techniques to cross-sectional data collected from a random sample of farm households located in Lake Naivasha basin, Kenya. Results indicate that there is a significant positive effect of implementing multiple soil conservation practices on crop productivity. However, we note that whether the additional benefits will cover the opportunity costs associated with the implementation of these practices will depend on farm specific attributes such as slope and the soil conservation effort. In cases where marginal benefits are not substantial to cover opportunity costs for implementation of soil conservation practices, intrinsic or external incentives could be necessary. Policy interventions could focus on offering technical assistance to farmers in selecting soil conservation practices that are best suited to their local condition.  相似文献

Forest carbon projects, in addition to climate mitigation and conservation benefits, are expected to improve local livelihoods and contribute to poverty alleviation across developing countries. Despite substantial investments over last decade, there is limited empirical evidence on the livelihood impacts of these projects especially across different socioeconomic categories.This paper aims to contribute to this knowledge gap through an analysis of the livelihood impacts across small, medium and large categories of participating farmers in a forest carbon project from the state of Haryana in India. Data from 107 households have been analysed to study the impacts in terms of foregone crop, fodder and fuel wood benefits. The analysis suggests that the project has adversely affected the livelihoods of all three categories of farmers. However, small and marginal farmers are the most distressed due to their low incomes, asset base and risk-bearing capacities.It raises critical project design issues such as binding land use, delayed accrual of benefits, static opportunity costs and displacement of existing economic activities, which have serious livelihood and equity implications. Unless these issues are addressed and strong safety nets are provided, forest carbon projects might create more poverty than wellbeing for marginal communities.  相似文献

The relationship between resource extraction activity and economic growth has been widely studied in the literature, and the resource curse hypotheses emerged as a theory to explain the effects of resource windfalls on national economies. However, within countries, resource booms and busts can have distinctive effects across local economies, as extractive regions face particular economic consequences unlikely to be observed in nonresource regions. Empirically, most studies analysing the resource curse have relied on cross‐country models to estimate effects and inform policy; however, the use of regional – within‐country – analysis has gained attention from scholars lately, promoted by two advantages: it avoids unobserved country heterogeneities confounding economic outcomes caused by resources and exploits the subnational quasi‐natural experimental conditions generated by endowments. This paper contributes to the resource curse literature by discussing its theoretical causes across scale (regional vs. national effects) and highlighting the empirical challenges involved in the analysis of mining economic impacts across regions. We complement the discussions by econometrically modelling economic growth across nonmetropolitan substate regions of Australia during a period of resource windfalls, finding that in most cases, resources have been a blessing for local economies, although negative effects have also been experienced in parts of the country.  相似文献

The behaviour of wild animal species in agricultural landscapes may confer benefits to growers through the provision of ecosystem services (e.g. control of agricultural pests) or inflict costs through direct or indirect damage to crops or livestock. The literature on the costs that species inflict or the benefits they provide has evolved largely independently with few attempts to synthesize information across studies. However, managing cost–benefit trade-offs to maximize agricultural productivity while ensuring native species conservation is vital to the future of ecologically sustainable agriculture. Using birds as a case study, we review the two bodies of literature on the costs and benefits attributed to bird activity in agricultural landscapes. In each case, we examine the major types of costs (e.g. consumption of crops) and benefits (e.g. pollination of crops) and assess approaches to quantifying these in terms of changes in crop yield or monetary value. We then synthesize this information to examine options for balancing cost–benefit trade-offs through coordinated and integrated management strategies that consider all aspects of species activity in agricultural landscapes. Employing strategies that successfully balance costs and benefits is fundamental to future food security and agricultural sustainability.  相似文献

Duck hunting is an issue — often controversial — that generates both benefits and costs to society. Hunters enjoy benefits from engaging in their sport, while those who have ethical concerns regarding the shooting of ducks endure costs. Some in the community fear that duck hunting puts pressure on the continued ecological viability of the hunted species, while others argue that the demand for hunting provides sufficient economic incentive for wetland conservation. Whether society as a whole should permit or restrict duck hunting is to some extent an empirical question: Are the costs to society of allowing duck hunting greater or less than the benefits it generates? Evidence presented in this paper addresses this question. The benefits enjoyed by people who hunt ducks in the upper south east of South Australia are estimated using the travel cost method. The ethical costs borne by the general community because of duck hunting are estimated using the choice modeling technique. Finally a threshold value analysis is used to assess the activities of Wetlands and Wildlife, a not‐for‐profit organization that manages wetlands in part for hunting.  相似文献

Although the adaptation strategies of smallholder farmers to climate change and its attendant hazards have attracted widespread attention, the quantitative detection and evaluation of their adaptive behaviors remains a difficult task that deserves further study. This article describes an empirical case study performed in southern China to examine the adaptation strategies of paddy farmers to agricultural drought. We collected first-hand data through household questionnaires, in-depth interviews with local managers, and farm-level land-use surveys. The effectiveness of the adaptation approaches of the farmers was assessed in terms of the ecological, economic, and social benefits. Our findings indicate that over the past three decades, when confronted with recurrent seasonal drought in a warming climate, farmers have gradually abandoned the double-cropping rice production and transformed their cropping patterns into a new diversified mode of “Rice-Cole, rice, cotton, seedling nursery, and coarse cereals”. Current farming practice reduces the vulnerability of local agriculture to drought, and allows farmers to diversify and improve their incomes, which contributes to enhanced resilience and adaptability to drought. However, the autonomous adaptation of farmers may primarily serve their interests of minimizing drought risk and maximizing economic profits but could also undermine the social benefits, such as regional grain security. A robust adaptation strategy should balance the ecological and economic benefits with social interests to maintain agricultural sustainability.  相似文献
