Available in PDF, EPUB and Kindle. Book excerpt: Ecosystem service valuation is becoming popular among the economists, ecologists, scientists and policy makers. As a result, various research, publications and programs have arisen and content of literature is developed rapidly. Even though this field of study is developing rapidly, Sri Lankan ecosystems have not yet been valued or evaluated yet in terms of economic returns. Hence, the main purpose of this study is to calculate and define economic value for each forest polygon of 2010 forest cover data base by using the value transferring approach. This data base will be an effective tool to have a fair cost-benefits analyses of development projects which are most likely planned to be implemented on forested landscapes. The value transferring approach was selected for this study considering the free availability of data and expensive and time-consuming nature of primary valuation approaches. This study includes two main analyses: an estimation of total economic value of all ecosystem services provided by forest ecosystems of Sri Lanka and an estimation of economic value of water services provided by the forest ecosystems within the Mahaweli River basin which is known as largest and longest river basin of Sri Lanka. For the first analysis, required reference values of ecosystems services were found from the equivalent biomes of TEEB database. These reference data were processed at three levels and standardized to 2019 US dollar values by following a standard procedure. These processed results regarding water services were used for the second analysis and the watershed boundaries, sub-watershed boundaries, stream network, pour points were created using Arc Map 10.8.1. According to the results of first analysis, the total annual economic value of all considered ecosystem services range from US $ 3.472 billion to US $ 138.818 billion and the estimation can be averaged at US $ 34.5 billion. Results further confirmed that mangrove forests are important and ecologically valuable by reaching to the highest per unit area annual economic value being estimated at US $ 42856 per hectare per year. The water service analysis revealed that the economic value of water services provided by all forest ecosystems within the Mahaweli river basin is US $ 67.9 million. Analysis further indicated that, US $ 11,247,073 worth of water services are produced by the 78,429 ha of forest lands within the Parakrama Samoodraya sub-watershed annually. These results of both analyses are important in future conservation and management decisions making, especially regarding identifying restoration and enrichment priorities, and as a progress monitoring tool.

Download or read book Ecosystem services may provide large economic values in Kenya and Vietnam A value transfer application based on results from a systematic literature review written by Hettiarachchi, Upeksha and published by Intl Food Policy Res Inst. This book was released on 2024-01-24 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study focuses on the valuation of ecosystem services in Kenya and Vietnam, two countries that have received much attention from the international development community for their biodiversity significance, opportunities for scaling, climate and poverty challenges, and political will. Using The Economics of Ecosystems and Biodiversity (TEEB) framework and the Millenium Ecosystem Assessment (MEA), this study estimates per hectare values of ecosystem services in Kenya and Vietnam based on a systematic literature review of studies on the values of ecosystem services in both countries. Provisioning services, such as medicines, timber, and non-timber forest products were better studied than regulating, supporting and cultural ecosystem services, underscoring the need for further research to better estimate the values of non-tangible services which would improve the estimation of total value of ecosystem services in Kenya and Vietnam. To complement the national level analysis, we selected forest biomes to conduct a value transfer analysis. Forests provide ecosystem service benefits worth $25.78 billion for Kenya and $35.6 billion in Vietnam in 2022 USD. In comparison, the agricultural sector contributed $48.50 billion to Vietnam’s GDP and $24.10 billon to Kenya’s GDP in 2021. The per hectare values for ecosystem services are used in a value transfer analysis to estimate the total value of forest ecosystem services in Vietnam and Kenya. The average per hectare value of ecosystem services provided by forests in Kenya is $5,718.50 ha−1 yr−1 estimated within a range spanning $1,609.44 to $15,606.62 ha−1 yr−1 , while Vietnam's forests demonstrate an average value of $3,650.20 ha−1 yr−1 , with a range of $84.93 to $8,978.16 ha−1 yr−1 . We project the loss of forests into 2050 and estimate the annual economic loss of ecosystem services at $48.08 million for Kenya and $76.29 million for Vietnam, respectively, if deforestation and forest degradation continue at the current rates. Our approach presents a comprehensive overview of diverse ecosystem services, equipping policymakers with a nuanced comprehension of ecosystems’ inherent value. By consolidating values from the literature into a national-level estimate, we provide compelling evidence at a broader scale for informed decision-making. Despite the well-known limitations of value transfer method and with caveats, the values presented in our paper can provide a guiding reference for incorporating these estimations into broader policymaking endeavors.

Download or read book The Economics of Ecosystems and Biodiversity Ecological and Economic Foundations written by Pushpam Kumar and published by Taylor & Francis. This book was released on 2012-12-20 with total page 454 pages. Available in PDF, EPUB and Kindle. Book excerpt: Human well-being relies critically on ecosystem services provided by nature. Examples include water and air quality regulation, nutrient cycling and decomposition, plant pollination and flood control, all of which are dependent on biodiversity. They are predominantly public goods with limited or no markets and do not command any price in the conventional economic system, so their loss is often not detected and continues unaddressed and unabated. This in turn not only impacts human well-being, but also seriously undermines the sustainability of the economic system. It is against this background that TEEB: The Economics of Ecosystems and Biodiversity project was set up in 2007 and led by the United Nations Environment Programme to provide a comprehensive global assessment of economic aspects of these issues. This book, written by a team of international experts, represents the scientific state of the art, providing a comprehensive assessment of the fundamental ecological and economic principles of measuring and valuing ecosystem services and biodiversity, and showing how these can be mainstreamed into public policies. This volume and subsequent TEEB outputs will provide the authoritative knowledge and guidance to drive forward the biodiversity conservation agenda for the next decade.
Download or read book Economic Valuation of Forest Ecosystem Services written by Aline Chiabai and published by . This book was released on 2009 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: By using ad hoc value transfer protocols, this paper offers a methodological contribution and provides accurate per hectare estimates of the economic value of some selected ecosystem services for all forest biomes in the world, identified following the Millennium Ecosystem Assessment taxonomy MEA. The research also estimates potential total economic losses from policy inaction in year 2050. Final results show that total losses are significant. The total figure is €78 billion, the greatest losses coming from North America and Mexico, followed by Africa, Russia and some Asiatic countries. Most of this loss is attributable to provisioning services and carbon sequestration, while only a minor part is due to loss of cultural services. In terms of biomes the greatest losses are from boreal and warm mixed forests, followed by tropical forests. These results may be surprising to some who argue that it is the loss of tropical forests, particularly the Amazon, that is the most significant. A detailed analysis, shows, however, that this is not the case. The best estimates point to greater losses in areas where use and non-use values are highest, which includes North America.

Download or read book Ecosystem Goods and Services from Plantation Forests written by Jürgen Bauhus and published by Earthscan. This book was released on 2010 with total page 273 pages. Available in PDF, EPUB and Kindle. Book excerpt: Plantation forests often have a negative image. They are typically assumed to be poor substitutes for natural forests, particularly in terms of biodiversity conservation, carbon storage, provision of clean drinking water and other non-timber goods and services. Often they are monocultures that do not appear to invite people for recreation and other direct uses. Yet as this book clearly shows, they can play a vital role in the provision of ecosystem services, when compared to agriculture and other forms of land use or when natural forests have been degraded. This is the first book to examine explicitly the non-timber goods and services provided by plantation forests, including soil, water and biodiversity conservation, as well as carbon sequestration and the provision of local livelihoods. The authors show that, if we require a higher provision of ecosystem goods and services from both temperate and tropical plantations, new approaches to their management are required. These include policies, methods for valuing the services, the practices of small landholders, landscape approaches to optimise delivery of goods and services, and technical issues about how to achieve suitable solutions at the scale of forest stands. While providing original theoretical insights, the book also gives guidance for plantation managers, policy-makers, conservation practitioners and community advocates, who seek to promote or strengthen the multiple-use of forest plantations for improved benefits for society.

Download or read book Lessons from Payments for Ecosystem Services for REDD Benefit Sharing Mechanisms written by Lasse Loft and published by CIFOR. This book was released on 2014-04-02 with total page 12 pages. Available in PDF, EPUB and Kindle. Book excerpt: Where benefits and costs accrue at different scales, financial intermediaries are needed to facilitate relations between global-scale buyers and local-scale providers of carbon sequestration and storage. These intermediaries can help to collect and distribute payments and to promote the scheme to potential beneficiaries. The benefits distributed should compensate for the transaction, opportunity and implementation costs incurred by stakeholders for providing ecosystem services. Therefore, calculating the costs and understanding who incurs them are essential for benefit sharing. Targeting benefits according to a set of criteria that match the objectives of the specific mechanism increases the mechanism’s efficiency. As the level of performance-based payments may not be able to compete with the opportunity costs of highly profitable land uses, performance-related benefit-sharing mechanisms should be focused on areas with moderate opportunity costs. Benefits should be divided into upfront payments to cover startup costs and to give an initial incentive for participation, and payments upon delivery of ecosystem services to ensure adherence to conditionality.

This book was released on 2013-11-26 with total page 404 pages. Available in PDF, EPUB and Kindle. Book excerpt: Agroforestry, the word coined in early seventies, has made its place in all the developed and the developing countries of the world and is now recognized as an important approach to ensuring food security and rebuilding resilient rural environments. India has been an all-time leader in agroforestry. The South and Southeast Asia region comprising India is often described as the cradle of agroforestry. Almost all forms of agroforestry systems exist across India in ecozones ranging from humid tropical lowlands to high-altitude and temperate biomes, and perhumid rainforest zones to parched drylands. The country ranks foremost among the community of nations not only in terms of this enormous diversity and long tradition of the practice of agroforestry, but also in fostering scientific developments in the subject. Agroforestry applies to private agricultural and forest lands and communities that also include highly erodible, flood-prone, economically marginal and environmentally sensitive lands. The typical situation is agricultural, where trees are added to create desired benefits. Agroforestry allows for the diversification of farm activities and makes better use of environmental resources. Owing to an increase in the population of human and cattle, there is increasing demand of food as well as fodder, particularly in developing countries like India. So far, there is no policy that deals with specifics in agroforestry in India. But, the Indian Council of Agricultural Research has been discussing on the scope of having a National Agroforestry Policy in appropriate platforms. However, evolving a policy requires good and reliable datasets from different corners of the country on the subject matter. This synthesis volume containing 13 chapters is an attempt to collate available information in a classified manner into different system ecologies, problems and solutions, and converging them into a policy support.

Download or read book The Economic Value of Forests in Supplying Local Climate Regulation written by Eugenio Figueroa and published by . This book was released on 2015 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Several authors have argued that forest ecosystems serve as a hedge against extreme climatic events at a local scale. Consequently, the local climate regulation ecosystem services provided by forests can be economically valued by evaluating the reduction (increase) in the insurance premium that risk-averse individuals are willing to pay when forest cover is marginally increased (reduced). This type of insurance value associated to forest ecosystems services is estimated to be USD 0.0733 per hectare of forest for Chilean farmers. The empirical framework proposed in this paper is useful and relevant for the cost-benefit analysis of natural resource conservation investments.
Download or read book Ecosystem Functions and Management written by Harpinder Sandhu and published by Springer. This book was released on 2017-03-21 with total page 222 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is the first book to provide vital information on key local ecosystems, their functions, state of health, and their role in development in an Asian context, particularly on the Indian subcontinent. It addresses six major ecosystems on the Indian subcontinent – mountain, rural, desert, forest, urban, and freshwater – and discusses their functions, how they support livelihoods and the economy, the impacts on ecosystem services, and management issues. Asia is home to nearly one third of the global population. With massive industrialization occurring at an increasing pace to support the lifestyles of a growing population, impacts on natural ecosystems are inevitable in this region. The book also explores the concepts, theory and practice regarding these key ecosystems by linking them with the livelihoods of a large population base and subsequently illustrating their importance for sustainable development in the region. Further, by suggesting policies and ways in which these systems can be maintained and enhanced, it facilitates better management of natural resources within the ecological constraints to achieve socio-economic objectives and move towards a green economy for sustainable and equitable development in the region.
