Ecological Importance

This paper collates seagrass studies from 2008- 2017. The focus of review is on the studies conducted in Philippines and in some areas of world in relation to this dynamic and most productive marine ecosystem the seagrass meadows. The review reveals that there is an abundance in diversity, distribution and cover of seagrass in different parts of the country, wherein articles written in other part of the world provides data and information on physical, biological and economic importance of Seagrass in the human lives. The cause of its destruction was found out to be mostly anthropogenic activities. Limitations on the conducted studies in the Philippines was shown as reflected in the collected studies that are generally done along the coastal areas in the Visayas and Mindanao regions. Which practically shows an opportunity to explore different places in Luzon for an assessment of Seagrass for its ecosystem resiliency, stability, management and sustainability. Foreign studies included in the review reflects studies on assessment of biophysical characteristics of the seagrasses with the use of modern technologies like remote sensing and management practices that illustrates market value of ecosystem services of seagrass meadows on its application for some small-scale fisheries. Knowledge gap on socio-ecological importance of seagrasses, economic valuation of this marine habitat ecosystem services and wake up call for policy maker to consider seagrasses in their proposal for management shift of this ecologically significant habitat are topics needing further investigations.

Holistic Method

The authors, with the awareness that climate change affects and changes the landscape, wanted to investigate how these changes are occurring within the metropolitan area of Tehran. Trying to keep a holistic method that embraces different disciplines, reasoning from large scale to small scale, the authors tried to study the main problems related to water scarcity and loss of green spaces. Subsequently they dedicated themselves to the identification of the present and missing ecosystem services, so that they could be used in the best possible way as tools for subsequent design choices. From the analysis obtained, the authors have created a masterplan with the desire to ensure a specific natural capital, the welfare of ecosystem services, and at the same time suggest good water management practices. It becomes essential to add an ecological accounting to the economic accounting, giving dignity to the natural system and the ecosystem services that derive from it.

Policy And Planning

Coastal and marine ecosystem (CME) services provide benefits to people through direct goods and services that may be harvested or enjoyed in situ and indirect services that regulate and support biological and geophysical processes now and in the future. In the past two decades, there has been an increase in the number of studies and journal articles designed to measure the economic value of the world’s CME services, although there is significantly less published research than for terrestrial ecosystems. This article provides a review of the literature on valuation of CME services along with a discussion of the theoretical and practical challenges that must be overcome to utilize valuation results in CME policy and planning at local, regional, and global scales. The review reveals that significant gaps exist in research and understanding of the broad range of CME services and their economic values. It also raises questions about the validity of aggregating ecosystem services as independent components to determine the value of a biome when there is little understanding of the relationships and feedbacks between ecosystems and the services they produce. Finally, the review indicates that economic valuation of CME services has had a negligible impact on the policy process in four main regions around the world. An alternative direction for CME services research would focus on valuing the world’s CME services in a wealth accounting framework.

Economic valuation of marine ecosystem services is strongly anchored within the logic of Marine Strategy Framework Directive (MSFD). An inventory and critical assessment of marine valuation studies was conducted within the European Union funded Policy-oriented marine Environmental Research for the Southern European Seas (PERSEUS) research project ( http://www.perseus-net.eu/ ) and this information was fed into a suitable, spatially explicit valuation database, namely Valuation database for Marine Ecosystem Services of Southern European Seas (V-MESSES), with the objective of providing monetary values for Southern European Seas (SES) to be used in cost–benefit and cost-effectiveness applications. At present, the database contains 93 studies offering over 110 value estimates for four categories and 20 subcategories of marine ecosystem services covering all regions of Mediterranean and Black Sea. The database enables so far the estimation of the aggregated value of all ecosystem services. However, the selection of appropriate, policy relevant value estimates is not a simple and straightforward task, since several conditions should be met in order to conduct effective and efficient value transfers. Bearing in mind the above limitations, tentative reference value estimates are compiled from the V-MESSES database for a number of coastal and marine ecosystem services, although not all service categories are covered sufficiently.

AbstractSeagrass habitats provide a range of goods and benefits to coastal communities by supporting ecosystem functioning, food provisioning, and cultural values. However, they are at risk worldwide from anthropogenic activities, climate change impacts and limited resources, which hamper efforts to protect them. Effective conservation planning requires prioritisation of sites based on multiple factors, including their relative value and vulnerability (VU). The current study examines the efficacy of combining two well-established approaches – ecosystem service assessments and habitat VU analyses – to test a method for determining conservation priority for selected seagrass meadows in Southeast Asia. Seven seagrass meadows around Southeast Asia were selected and scored by the authors based on (1) the cumulative contribution of 12 ecosystem services (ES) and the condition of the meadows, (2) VU from 16 anthropogenic threats, which were each ranked against five factors (spatial scale, frequency, functional impact, resistance and recovery time) and (3) the combination of the two approaches to create a single numerical index. Prioritisation of sites differed when meadows were scored solely for the ES they provide, compared to how vulnerable they are to anthropogenic threats. The new combined analysis brought the two metrics together to give conservation priority to sites where management intervention will yield maximum conservation benefits from conservation effort, and resulted in the prioritisation of three sites: Barrang Lompo (Indonesia), Cape Bolinao (Philippines) and Beting Tanjung Kupang (Malaysia). This method is easy to use and does not require great technical expertise. It is also auditable, allowing for clear and transparent understanding of decision-making process.

The Impact

Tanguar haor wetland is one of the listed Ramsar sites enrich with biodiversity variety and provides several ecosystem services with significant contribution to the national economy of Bangladesh. But these services were decreasing day by day due to natural and anthropogenic activities. The purposes of this study were to identify the utilized ecosystem services by communities, economic values of utilized ecosystem services and the basic reasons for depleting of ecosystem services. Data were collected through baseline survey, checklists, face to face questionnaire survey and focus group discussion (FGD) from 120 residential respondents and 50 tourist respondents by accepting random sampling techniques during November, 2016 to September, 2017. Physiochemical characteristics of the water were determined where the mean temperature and pH were 28.26°C and 7.72 respectively. The highest TDS, EC, DO, NO3 and PO4 values were 1020 (mg L−1), 1460 (μS cm−1), 8.56 (mg L−1), 1.769 (mg L−1) and 0.078 (mg L−1), respectively. Commonly utilized ecosystem services were crops, vegetables, fuel, fresh water, fishes and migratory birds, climate regulation, water purification, natural hazards protection, aesthetic, social relations, recreation & tourism, health benefit, primary production, nutrient cycling, water cycling habitats for species and provision of habitat etc. Market Value Method (MVM) and Contingent Value Method (CVM) were applied to measure the economic value of Tanguar haor wetland services. DPSIR framework and Impact Matrix (IM) were applied for conceptual analysis to identify the effects on ecosystem services. Total economic value of 39 ecosystem services of Tanguar haor was estimated at 174039980 BDT year−1. Mismanagement of biodiversity, over exploitation, sedimentation of haor, climate change, illegal hunting, land use changes and habitat changes were the responsible factors for depleting ecosystem services. The impact factor (4.161) was identified by natural and anthropogenic factors on ecosystem services. There have a vast prospect of the Tanguar haor wetland services for near communities. Finally the research suggested several sustainable management approaches which have the potentiality to protect the services of the wetland.J. Bangladesh Agril. Univ. 16(2): 237-243, August 2018

Abstract Economic valuation of marine ecosystem services in the Baltic Sea region has gained importance, as policy-makers are recognizing their decline and focusing on achieving good environmental status there in terms of, for example, reduced eutrophication. Parallel with this development, several initiatives have been launched, leading to a large number of economic valuation studies. However, current research indicates that neither a common approach to classifying ecosystem services nor a widely accepted methodological framework for assessing their economic value exist yet. This paper seeks to shed light on the current state of the economic valuation of ecosystem services provided by the Baltic Sea through reviewing all currently available empirical studies on the topic. The results indicate that only a few ecosystem services, including recreation and reduction of eutrophication, have been extensively monetarily valued, and still lack cross-study methodological consistency, while many other marine ecosystem services have rarely or never been valued with economic methods. The paper concludes that existing economic valuation studies provide only limited practical guidance for policy-makers intending to improve the environmental status of the Baltic Sea. There is a need for more widely shared agreement on the systematic nature of marine and coastal ecosystem services and especially on a coherent methodological framework for assessing their economic value.

AbstractThe systematic designation of protected areas is a key strategy in modern biodiversity conservation. As for now, the Natura 2000 system of the European Union (EU) is the largest coordinated network of conservation areas worldwide. Since this scheme has a focus on forests, its effectiveness substantially depends on small-scale private forest owners who represent the largest forest ownership group in Europe. We conducted a quantitative survey (n = 1671) in Northwest Germany focusing on the perceived importance of ecosystem services, the performance of management practices, nature conservation attitudes, as well as stand characteristics of small-scale private forest owners with and without Natura 2000 sites. Forest owners perceived regulating and cultural services as more important than provisioning ecosystem services while having a multifunctional perspective on their forest. Owners with Natura 2000 sites had a stronger focus on resource use and, with the exception of habitat-tree protection, did not perform conservation measures more frequently than those without. Moreover, we found more negative nature conservation attitudes among this ownership group. In conclusion, the Natura 2000 scheme needs to be more strongly adapted to the demands of small-scale private forest owners, for example by increasing profound participation and establishing a results-based incentive scheme for conservation measures. The perspectives of small-scale private forest owners have to be considered comprehensively to ensure the effective and sustainable implementation of the Natura 2000 conservation network.
