Piloting a systematic framework for public investment in regional natural resource management: Dryland salinity in Australia

The Salinity Investment Framework (SIF3) is designed to help environmental managers make better policy decisions about protecting key assets under threat of dryland salinity, a major degradation problem in Australia. This study reports results from applying SIF3 in partnership with two regional organizations (in the states of Victoria and Western Australia) with contrasting institutional powers and structures. We also engaged relevant policy makers with a view to influencing national policy. Available knowledge, science, and data were used to develop region-specific recommendations for public investment in salinity management. SIF3 proved easy to apply, requiring minimal changes from its original version. Establishing trust and credibility with stakeholders was extremely important. More time was required to be spent on communicating what SIF3 was and what it would mean for stakeholders than in applying it in the catchments. In both regions, recommendations included making a clear distinction between localized assets (such as a particular wetland) and dispersed assets (such as agricultural land as a whole); more targeted investment in spatially identified localized assets; using a broader range of policy tools; basing recommendations on the levels of public and private net benefits; anticipating the adoptability of sustainable land-management practices; and formally integrating relevant scientific, economic and social information with community values. The differences between current action and recommendations were significant in both regions, particularly in Victoria. As a result of our work both regions have decided to implementing a similar asset-based approach covering various environmental threats in addition to dryland salinity. The research indicates that it is feasible to use decision frameworks such as SIF3 to improve the rigour of decision making by community-based environmental management organizations. A broader range of policy tools are needed for dryland salinity, with less reliance on extension and small grants, and more emphasis on intervention around key assets and investment in technology development. We have influenced policy makers to some extent at state level and nationally through discussion of SIF3 in a national inquiry, preparation of a policy paper for peak multi-government policy committees, briefings and provision of advice on policy design. Despite this, achieving significant policy change at the state and national levels remains difficult for a number of reasons. Governments give limited signals to environmental managers to achieve environmental outcomes, being more concerned with community participation objectives and political considerations. We hope for significant policy change with increased scrutiny about sound decision making and public accountability.     

Integrated assessment of public investment in land-use change to protect environmental assets in Australia

A framework for comprehensive integrated assessment of environmental projects is developed and applied in partnership with a regional environmental body. The framework combines theory with practice, bringing a pragmatic and efficient approach to the rigorous assessment of projects for a large number of environmental assets in the north central region of the state of Victoria, Australia. The approach is codified as the Investment Framework for Environmental Resources (INFFER). The analysis assisted the environmental body to make strong business cases for a number of environmental projects, resulting in funding for those projects. Key features of the study include extensive participation of decision makers and stakeholders, integration of a comprehensive set of information about projects, explicit assessment of uncertainties and information gaps, and analysis of the most appropriate policy mechanism for each project. The process of applying the framework involved four steps: identification of around 300 important environmental assets in the region, filtering the list of assets to remove those that are less likely to provide opportunities for cost-effective public investment, development and detailed assessment of projects for a subset of assets, and negotiation of funding for projects. Implications for land-use policy include that environmental projects vary widely in their cost-effectiveness, requiring careful targeting of funds if environmental benefits are to be maximised. Many existing environmental programs use simplistic analyses to support decision making, resulting in missed opportunities for substantially greater environmental benefits. Promoting adoption of improved analytical methods is very challenging, requiring changes in mind-set and culture in environmental organisations. Widespread adoption is unlikely unless funders create incentives by rewarding those project proponents who undertake rigorous and comprehensive project assessments that focus on achievement of environmental outcomes.     

ULYSSES REVISITED — A CLOSER LOOK AT THE SAFE MINIMUM STANDARD RULE

The Safe Minimum Standard (SMS) Rule has been developed as a decision rule involving environmental assets, particularly species, that face some risk of extinction. The SMS rule has been presented by Bishop (1978) (1979) and Randall (1991) as a better decision process than the use of cost benefit analysis (CBA). This paper explores the relationship between the SMS rule and CBA. It shows that there is a tandem effect in operation because the use of both rules rely on the same underlying preferences in society. There is potential for the two rules to achieve the same results, and doubt over whether the SMS rule is an independent control over CBA. Instead, the SMS rule may simply operate as a nagging mechanism for issues of particular interest. Its use can be seen as a signal to switch to a more intensive examination of costs and benefits, and justified in this format because the benefits of more accurate decisions outweigh the costs of operating the SMS rule. The application of the SMS rule will vary according to the justification for its use.     

Do changes in credit ratings of REITs affect their capital structure decisions?

Existing research has highlighted the high leverage ratio of Real Estate Investment Trusts (REITs). To the extent that credit rating is important to REITs when sourcing for capital from the public debt markets, our paper investigates the effect of changes in REIT credit ratings on capital structure decisions while controlling for endogeneity effects. Our results indicate that REITs that face the prospect of an imminent credit rating downgrade issue approximately 11% less debt net of equity as a percentage of total assets than other REITs. This effect is asymmetric in that positive rating outlooks do not have a significant impact on REIT capital structure activities.     

Duck Hunting and Wetland Conservation: Compromise or Synergy?

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.

Financial costs and benefits of a program of measures to implement a National Strategy on Biological Diversity in Germany

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.     

Analysing the Agricultural Costs and Non‐market Benefits of Implementing the Water Framework Directive

Implementation of the Water Framework Directive (WFD) represents a fundamental change in the management of water in Europe with a requirement that member states ensure ‘good ecological status’ for all water bodies by 2015. Agriculture is expected to bear a major share of WFD implementation costs as it is compelled to reduce the emission of diffuse water pollutants. The research outlined here comprises interdisciplinary modelling of agricultural land use, hydrology and consequent water quality effects to consider both agricultural costs and the non‐market recreational use (and potentially non‐use) values that implementation of the Directive may generate. A theme throughout the research is the spatial distribution of the costs and benefits of WFD implementation, which is addressed through the use of GIS techniques in the modelling of agricultural land use, the integration of land use and hydrological models, and the estimation, aggregation and transfer of the economic value of the benefits.     

Analysing foregone costs of communities and carbon benefits in small scale community based forestry practice in Nepal

Reducing emissions from deforestation and forest degradation, conservation and sustainable management of forests and enhancement of forest carbon (REDD+) are considered to be important cost effective approaches for global climate change mitigation; therefore, such practices are evolving as the REDD+ payment mechanism in developing countries. Using six years (2006–2012) data, this paper analyses trade-offs between carbon stock gains and the costs incurred by communities in generating additional carbon in 105 REDD+ pilot community forests in Nepal. It estimates foregone benefits for communities engaged in increasing carbon stocks in various dominant vegetation types. At recent carbon and commodity prices, communities receive on average US$ 0.47/ha/year of carbon benefits with the additional cost of US$ 67.30/ha/year. One dollar’s worth of community cost resulted 0.23 Mg of carbon sequestration. Therefore, carbon payment alone may not be an attractive incentive within small-scale community forestry and should link with payments for ecosystem services. Moreover, the study found highest community sacrificed benefits in Shorea mixed broadleaf forests and lowest in Schima-Castanopsis forests, while carbon benefits were highest in Pine forests followed by Schima-Castanopsis forests and lowest in Rhododendron-Quercus forests. This indicates that costs and benefits may vary by vegetation type. A policy should consider payment for other environmental services, carbon gains, co-benefits and trade off while designing the REDD+ mechanism in community based forest land use practice with equitable community outcomes. The learning from this study will help in the formulation of an appropriate REDD+ policy for community forestry.     

水资源资产负债表构建的若干问题探析

在分析国内外水资源资产负债表研究现状的基础上,剖析了现行水资源资产负债表理论研究中存在的主要问题:没有明确的水资源资产概念、会计主体不明晰、缺乏合理的会计分期、水质未与水资源资产关联、没有统一的水资源资产(负债)核算方法。通过研究得到以下结论:通过现代科学技术手段取得但因未投入使用而未发挥效益的水资源可作为潜在水资源资产,当其实际带来经济利益时方可称为水资源资产;水资源资产负债表的会计主体可以是国家、流域、地方政府,将来随着水资源管理的完善也可以是某一供水系统;水质应与水资源资产账户密切联系;可综合采用日历年度和水文年度进行会计分期;应按一定标准统一水资源资产(负债)核算。     

Perceived importance of ecosystem services in the Białowieża Forest for local communities – Does proximity matter?

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.     

Public preferences for controlling an invasive species in public and private spaces

Discrete choice experiments have been used in this case study to assess community benefits for the control of red imported fire ants, an aggressive ant species that were introduced by accident in 2001 to Brisbane, Australia. This invasive species could have substantial impacts on agricultural production, biodiversity, ecosystem services, infrastructure and communities. Values for avoiding impacts on three particular land uses have been assessed in this study with discrete choice experiments. The results indicated that on a per hectare basis, the value estimates to avoid infestation in public areas (schools and parks), were much higher than for private areas (housing) or natural bushland areas (protected native vegetation). There were high levels of support for eradication rather than containment strategies, despite the additional costs involved. The use of both random parameters logit and latent class models demonstrates that there is a significant heterogeneity in preferences and values for controlling or eradicating the invasive species, indicating that it may be challenging to gain and maintain political support for management options, particularly if these involve large costs or inconvenience to households.

Perceptional differences in the factors of local acceptance of spent nuclear fuel repositories

In the process of land use planning, massive social costs are incurred as various conflicts arise due to the location of locally unwanted land-use (LULU) such as spent nuclear fuel repositories. The factors affecting local acceptance of such facilities may vary according to individuals’ perceptional differences. This study aims to examine the differences in factors affecting local acceptance in regards to residents’ risk perception of spent nuclear fuel repositories. To do so, Q methodology was adopted. Three perceptional types—safety concerns-government distrust (type 1), safety trust-government trust (type 2), and safety concerns-conflict avoidance (type 3)—were identified and the differences in local acceptance factors among these types were verified via path analysis. The results showed that risk perception had the highest influence on local acceptance for types 1 and 3, whereas economic feasibility had the greatest influence for type 2. The methodology and results of this study may contribute to developing a policy on siting LULU facilities in consideration of local acceptance and the risk perception of residents.     

Measuring environmental incomes beyond standard national and ecosystem accounting frameworks: testing and comparing the agroforestry Accounting System in a holm oak dehesa case study in Andalusia-Spain

The standard System of National Accounts (SNA) omits the costs of the environmental inputs from nature and the environmental fixed asset degradation from the national/sub-national natural working landscapes. The United Nations Statistic Division (UNSD) is currently drafting the standardization of the Experimental Ecosystem Accounting (EEA), as part of the System of Environmental-Economic Accounting (SEEA). The EEA- aims to mitigate some of the limitations of the SNA by extending the concept of economic activity and explicitly incorporating ecosystem services and environmental assets provided by nature in the estimates of net value added, adjusted according to the costs of the environmental inputs consumed and the environmental fixed asset degradations of ecosystem. However, the NVAad proposed in the ongoing draft of the EEA is inconsistent in that it omits the manufactured costs of the public economic activities of the new government institutional sub-sector of the ecosystem trustee. In addition, the ongoing methodological guidelines of the EEA do not propose to estimate the environmental income. This implies that there is not a single indicator that integrates the ecosystem services obtained and the evolution of the environmental assets in the natural working landscapes in which the private and public activities are valued. The objective of this research is to discuss conceptually and compare the measurements of ecosystem services and environmental incomes in the extended Agroforestry Accounting System (AAS), and in refined versions of the official SNA and the ongoing EEA methodologies, through a case study of privately-owned holm oak dehesas working landscapes in Andalusia-Spain. This comparison shows that the refined SNA and the refined EEA in their current state of development do not allow the complete visualization of the environmental income contribution to the total income of the natural working landscapes. We also discuss the advances provided by the AAS extended accounting methodology that would be relevant for the EEA next improvements.     

Estimating the joint effect of multiple soil conservation practices: A case study of smallholder farmers in the Lake Naivasha basin,Kenya

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.     

Situating community forestry enterprises within New Institutional Economic theory: What are the implications for their organization?

Community forestry enterprises (CFEs) have gained considerable traction with rural development and forestry practitioners as models for community development, poverty alleviation, and conservation. This paper uses New Institutional Economic theory to identify the key organizational features and potential inherent weaknesses of CFEs. NIE theory focuses on arguments of economic efficiency, specifically transaction cost reductions that serve as incentives for collective action by groups of owners. Examples are given to show how the organization of CFEs reduced transaction costs stemming from interactions with industrial loggers and service providers. However, the creation of these community enterprises goes beyond simple transaction cost reductions and economic justifications. Additional unquantifiable benefits, such as self-determination, control over resources that communities have historically used, application of acquired skills, political representation, and application of acquired skills to name a few, are also secured through community ownership. These benefits however do not come without a cost. As enterprises where ownership rights are incomplete or ill-defined and which do not operate with the incentives of investor-owned firms, CFEs have little to no initial capital pool and experience considerable investment limitations due to limited wealth, horizon problems, and unsolved issues with moral hazard vis-à-vis banks. CFEs also face important management and collective decision-making challenges. In spite of their institutional weaknesses, it is apparent that many societies have decided that the benefits of community ownership far outweigh their ownership costs. State intervention and policy have played an important role in building the necessary supportive framework for the development of these enterprises. NIE as a dominant model for understanding alternative entrepreneurial forms was useful for identifying some important aspects of CFEs that, in a profit-driven economy, can constitute weaknesses that place them at a disadvantage with investor-owned firms. This analysis informs where policy should be targeted if CFEs are to be supported and fostered.     

The costs and benefits of land fragmentation of rice farms in Japan*

Land fragmentation, in which a farm operates multiple, separate plots of land, is a common phenomenon in Japan and many other countries. Usually, land fragmentation is regarded as a harmful phenomenon as it increases production costs and reduces the advantages of scale economies. However, it is also known that fragmentation may have beneficial effects in reducing risk through spatial dispersion of plots. Thus, land fragmentation has both costs and benefits, and whether it is beneficial or harmful is determined by the magnitude of these costs and benefits. This article investigates the costs and benefits of land fragmentation empirically using panel data from Japanese rice farms. The empirical results reveal that fragmentation increases production costs and offsets economies of size, and these impacts strengthen as farm size increases. Moreover, although fragmentation does reduce production risk, its monetary value is far below the cost of land fragmentation. From these findings, we conclude that land fragmentation is an impediment to efficient rice production in Japan.     

Underground assets: potato biodiversity to improve the livelihoods of the poor

Vulnerability and limited assets both constrain the options of poor people, especially smallholder farmers. But the poor often also possess a range of potentially valuable natural, physical, financial, human and social-capital assets. Development interventions requiring high levels of assets that poor people do not have are unlikely to reduce poverty, but those which build on what they do have can build assets and so improve their options. Producing and processing potatoes are important livelihood strategies for millions of the poor. A careful understanding of the context and strategies of the poor can help indicate how potatoes can also be used to reduce poverty. This paper employs the Sustainable Livelihoods Framework to examine these issues, using the Papa Andina case in the Andes as an example of new approaches to use potato diversity to improve livelihoods in a transforming development context. The Papa Andina regional initiative, together with its national partners, helps Andean farmers build new livelihood strategies using the genetic diversity of potatoes, local knowledge and social capital—assets that are often undervalued. But this does not occur in a vacuum; a range of policies and institutions are required, including, for example, collective action among farmers and interaction with outsiders such as market agents and agricultural service providers in order to foster market chain innovation and to access and build market opportunities. Accurate understanding of the changing context of producers, processors and consumers can help ensure that potatoes play a role in improving the welfare of the poor.     

The effect of spatial interdependencies on prioritization and payments for environmental services

Empirical studies and on-the-ground policies assessing optimal selection of projects in the context of payments for environmental services programs rarely consider spatial proximity of one project to other projects. This occurs despite evidence from theoretical and ecological studies that benefits are often spatially interdependent. This paper develops a flexible construct of “spatial synergy benefits” using the principles of Newtonian gravity similar to efforts in other application areas. This approach is novel to the literature on environmental preservation and, as a systematic method, can account for a wide variety of spatial interdependencies. The empirical setting for the application is farm and forest preservation in Delaware, with a quadratic knapsack algorithm used to select the optimal set of parcels. Application results show that the specific level of the spatial synergy benefit measure does not significantly alter the number of parcels and acreage preserved, but that the composition of the optimal set changes as agglomeration preferences increase. These changes in the optimal targeted set indicate a potential bias in past research on PES selection. Policy makers informed by methods that do not explicitly account for spatial agglomeration preferences often make incorrect investment choices from a cost-effectiveness perspective.
