Mapping Ecosystem Services for Land Use Planning,the Case of Central Kalimantan

Indonesia is subject to rapid land use change. One of the main causes for the conversion of land is the rapid expansion of the oil palm sector. Land use change involves a progressive loss of forest cover, with major impacts on biodiversity and global CO₂ emissions. Ecosystem services have been proposed as a concept that would facilitate the identification of sustainable land management options, however, the scale of land conversion and its spatial diversity pose particular challenges in Indonesia. The objective of this paper is to analyze how ecosystem services can be mapped at the provincial scale, focusing on Central Kalimantan, and to examine how ecosystem services maps can be used for a land use planning. Central Kalimantan is subject to rapid deforestation including the loss of peatland forests and the provincial still lacks a comprehensive land use plan. We examine how seven key ecosystem services can be mapped and modeled at the provincial scale, using a variety of models, and how large scale ecosystem services maps can support the identification of options for sustainable expansion of palm oil production.     

Digging Deeper: A Case Study of Farmer Conceptualization of Ecosystem Services in the American South

The interest in improved environmental sustainability of agriculture via biodiversity provides an opportunity for placed-based research on the conceptualization and articulation of ecosystem services. Yet, few studies have explored how farmers conceptualize the relationship between their farm and nature and by extension ecosystem services. Examining how farmers in the Southern Piedmont of South Carolina discuss and explain the role of nature on their farm, we create a detail-rich picture of how they perceive ecosystem services and their contributions to the agroeconomy. Using 34 semi-structured interviews, we developed a detail-rich qualitative portrait of these farmers’ conceptualizations of ecosystem services. Farmers’ conceptualization of four ecosystem services: provisioning, supporting, regulating, and cultural are discussed, as well as articulation of disservices. Results of interviews show that most interviewees expressed a basic understanding of the relationship between nature and agriculture and many articulated benefits provided by nature to their farm. Farmers referred indirectly to most services, though they did not attribute services to biodiversity or ecological function. While farmers have a general understanding and appreciation of nature, they lack knowledge on specific ways biodiversity benefits their farm. This lack of knowledge may ultimately limit farmer decision-making and land management to utilize ecosystem services for environmental and economic benefits. These results suggest that additional communication with farmers about ecosystem services is needed as our understanding of these benefits increases. This change may require collaboration between conservation biology professionals and extension and agriculture professionals to extended successful biomass provisioning services to other ecosystem services.     

Effects of Fish Stocking on Ecosystem Services: An Overview and Case Study Using the Stockholm Archipelago

In this article, we focus on documented and possible effects of fish stocking in terms of ecosystem services. The increasing use of fish stocking between 1970 and 2000 in the semiurban setting of Stockholm archipelago, Sweden, is used as case study. The objective is to analyze this management practice from an ecosystem perspective, accounting for both the ecological and social context of releasing fish. The results show that enhancements of four native species (Salmo S. trutta, Salmo salar, Stizostedion lucioperca, and Anguilla anguilla) have dominated over new introductions of one nonnative species. (Oncorhynchus mykiss). The major objective has been to increase fish catches for local resource users. Involved stakeholders include three management agencies, one hydropower company, and several local sport fishing associations. Documented effects focus on recapture and production rates. However, our analysis suggests that additional positive or negative effects on biodiversity, food web dynamics, mobile links, or ecological information may also result, with possible consequences for the long-term provision of food, game, and aesthetic values. We conclude that a more adaptive and cooperative management approach could benefit from a deeper analysis of where, when, and what species is released, by whom, which stakeholders that use the fish and those ecosystem services the fish generate, and of the role of formal and informal institutions for monitoring and evaluating the success of releasing fish.     

A Case Study of Ecosystem Services in Urban Planning in Finland: Benefits,Rights and Responsibilities

The concept of ecosystem services is entering the agenda of land-use planning and scientists optimistically expect it to inform planners and decision-makers about the benefits that ecosystems provide. While tools and methods have been developed for mapping and valuing ecosystem services, only little attention has been paid to the practical application of the approach or its institutional preconditions and implications. We empirically analysed two urban planning processes for building residential areas in the outskirts of growing population centres in Finland. Our analysis of documents and interviews with planners focused on the benefits provided by ecosystems as well as the associated rights and responsibilities. We found that the concept ‘ecosystem service’ was not used, yet various benefits were identified. The rights of different stakeholders to ecosystem services were not explicitly identified, but many ecosystem services were perceived as public goods and particularly access to recreation was highlighted as an important justification for green areas. The results show that while the ecosystem services approach introduces new insights to land-use planning, it is still not embedded in the current practices or institutions. Operationalizing ecosystem services requires institutional adaptation, case-specific tailoring of methods, and deliberation among practitioners and stakeholders.

A Multiattribute Index for Assessing Environmental Impacts of Regional Development Projects: A Case Study of Korea

Evaluating environmental impacts has become an increasingly vital part of environmental management. In the present study, a methodological procedure based on multiattribute utility theory (MAUT) has been applied to obtain a decision-maker's value index on assessment of the environmental impacts. The paper begins with an overview of MAUT. Next, we elicited strategic objectives and several important attributes, and then structured them into a hierarchy, with the aim of structuring and quantifying the basic values for the assessment. An environmental multiattribute index is constructed as a multiattribute utility function, based on value judgements provided by a decision-maker at the Korean Ministry of Environment (MOE). The implications of the results are useful for many aspects of MOE's environmental policies; identifying the strategic objectives and basic values; facilitating communication about the organization's priorities; and recognizing decision opportunities that face decision-makers of Korea.     

Development of Indicators to Assess Economic Vulnerabilities to Changes in Ecosystem Services: Case Study of Counties in Maryland,USA

We develop indicators showing the relative environmental burdens that human activities place on locales for a given level of economic benefits. The main purpose is to develop tools that allow us to examine the potential vulnerabilities within economies to changes in resource conditions. The indicators of pollution emission or resource consumption per job can be used to identify potential challenges to resource and industry managers and to compare areas in terms of their ability to adapt to change. For example, if a large number of area jobs are dependent on abundant water, this indicates a vulnerability to a reduction in water availability for industrial use. We develop a case study for 23 counties and 1 city in Maryland to examine the usefulness and limitations of the indicators. Our case study demonstrates that the indicators provide an informative view into patterns of local economic activity and use of an area’s environmental goods and services. In contrast to patterns for total environmental burdens (e.g., total SO₂ emissions) that are typically reported, the rates of environmental burden per job are not simply correlated with high or low economic output. Thus, the indicators represent distinct patterns of environmental burdens per job that reflect reliance on environmental services. The indicators have some limitations when used at this fine scale because they can misrepresent conditions in counties in which economic sectors are dominated by one or a few businesses. For this reason, the indicators are best used as a regional screening tool.

The Impacts of Water Conservation Strategies on Water Use: Four Case Studies1

Tsai, Yushiou, Sara Cohen, and Richard M. Vogel, 2011. The Impacts of Water Conservation Strategies on Water Use: Four Case Studies. Journal of the American Water Resources Association (JAWRA) 47(4):687‐701. DOI: 10.1111/j.1752‐1688.2011.00534.x Abstract: We assessed impacts on water use achieved by implementation of controlled experiments relating to four water conservation strategies in four towns within the Ipswich watershed in Massachusetts. The strategies included (1) installation of weather‐sensitive irrigation controller switches (WSICS) in residences and municipal athletic fields; (2) installation of rainwater harvesting systems in residences; (3) two outreach programs: (a) free home indoor water use audits and water fixture retrofit kits and (b) rebates for low‐water‐demand toilets and washing machines; and (4) soil amendments to improve soil moisture retention at a municipal athletic field. The goals of this study are to summarize the effectiveness of the four water conservation strategies and to introduce nonparametric statistical methods for evaluating the effectiveness of these conservation strategies in reducing water use. It was found that (1) the municipal WSICS significantly reduced water use; (2) residences with high irrigation demand were more likely than low water users to experience a substantial demand decrease when equipped with the WSICS; (3) rainwater harvesting provided substantial rainwater use, but these volumes were small relative to total domestic water use and relative to the natural fluctuations in domestic water use; (4) both the audits/retrofit and rebate programs resulted in significant water savings; and (5) a modeling approach showed potential water savings from soil amendments in ball fields.     

Communication in Ecosystem Management: A Case Study of Cross-Disciplinary Integration in the Assessment Phase of the Interior Columbia Basin Ecosystem Management Project

Effective communication is essential to the success of collaborative ecosystem management projects. In this paper, we investigated the dynamics of the Interior Columbia Basin Ecosystem Management Projects (ICBEMP) cross-disciplinary integration process in the assessment phase. Using a case study research design, we captured the rich trail of experience through conducting in-depth interviews and collecting information from internal and public documents, videos, and meetings related to the ICBEMP. Coding and analysis was facilitated by a qualitative analysis software, NVivo. Results include the range of internal perspectives on barriers and facilitators of cross-disciplinary integration in the Science Integration Team (SIT). These are arrayed in terms of discipline-based differences, organizational structures and activities, individual traits of scientists, and previous working relationships. The ICBEMP organization included a team of communication staffs (CT), and the data described the CT as a mixed group in terms of qualifications and educational backgrounds that played a major role in communication with actors external to the ICBEMP organization but a minor one in terms of internal communication. The data indicated that the CT-SIT communication was influenced by characteristics of actors and structures related to organizations and their cultures. We conclude that the ICBEMP members may not have had a sufficient level of shared understanding of central domains, such as the task at hand and ways and timing of information sharing. The paper concludes by suggesting that future ecosystem management assessment teams use qualified communications specialists to design and monitor the development of shared cognition among organization members in order to improve the effectiveness of communication and cross-disciplinary integration.

生态系统服务价值非货币量核算:理论框架与方法学

1997年两个开创性的著作,即Gretchen Daily主编的Nature’s Services:Societal Dependence on Natural Ecosystems一书及同年Robert Costanza在Nature上发表的The Value of the World’s Ecosystem Services and Natural Capital,引发了关于生态资本和生态系统服务、政策等研究的热潮。中国近几年来也将生态文明建设提到了前所未有的高度,并提出了一系列以生态系统服务价值核算为前提的制度和措施。基于此,本研究首先综述了现有生态系统服务分类体系及其存在的不足,剖析了现有核算生态系统服务价值的两类方法,即货币量方法和非货币量方法的核心差异点与可能的融合点,构建了基于能值分析方法和融合货币量核算方法的非货币量生态系统服务功能的新的核算框架,包括:(1)重新分类了生态系统服务价值,即直接价值(增加NPP、固碳释氧、增加土壤、补给地下水/涵养水源、提供水源水电和农产品等)、间接价值(净化大气、水、土壤、人畜排泄物和减少水土流失/侵蚀等)和存在价值(调节气候、调蓄水量、调节径流、旅游休闲、文化教育、维持生物多样性等)三大类;(2)确立了各类生态系统服务价值的核算方法体系;(3)厘清了核算中的加和原则等,以避免重复计算。该理论和方法学是解决现有生态系统服务价值核算方法不足的尝试和完整的方法论构建。     

Environmental Subsidiarity as a Guiding Principle for Forestry Governance: Application to Payment for Ecosystem Services and REDD+ Architecture

This article describes and proposes the “environmental subsidiarity principle” as a guiding ethical value in forestry governance. Different trends in environmental management such as local participation, decentralization or global governance have emerged in the last two decades at the global, national and local level. This article suggests that the conscious or unconscious application of subsidiarity has been the ruling principle that has allocated the level at which tasks have been assigned to different agents. Based on this hypothesis this paper describes the principle of subsidiarity and its application to environmental policies within forest governance and proposes the “environmental subsidiarity” principle as a critical conceptual tool for sustainable resource management. The paper explains as an example how “environmental subsidiarity” is the key principle that can link payment for ecosystem services (PES) with environmental public policies and applies this principle with all its political consequences to reducing emissions from deforestation and forest degradation, and enhancing forest carbon stocks in developing countries (REDD+) architecture. It concludes by showing how the adoption of “environmental subsidiarity” as a ethical principle could help to maximize benefits to all stakeholders involved in PES schemes such as REDD+.     

Estimating the Benefits of Environmental Enhancement: A Case Study of the River Darent

The provision of leisure facilities is usually assessed on their value to users. This paper outlines the use of contingent valuation methods in an ex ante appraisal of the costs and benefits of enhancing river flow for recreational purposes in a low flow river. A number of rivers in England and Wales experience low flows, especially during summer months, due to over abstraction of water, creating a trade-off between leisure uses and the demands of water consumers. The sequential benefits of enhanced flows are estimated from those associated with abstraction up to licensed limits: to river flow at 70% of licensed abstraction levels; to flow levels required for an environmentally acceptable flow regime, which would permit leisure activities such as fishing, enhanced scenic walking and wildlife encounters. These benefits are compared to the costs which would be incurred to achieve these enhanced flow regimes. The study illustrates the importance of including non-user benefits in benefit-cost analysis, if leisure provision is to be provided in certain areas.
