Design: Eva Kok Translation: Ninette de Zylva (editing) Printed by: Digigrafi, Wageningen, the Netherlands ISBN Agromisa: 90-8573-027-9 ISBN CTA: 92-9081-327-X Foreword Non-timber forest products (NTFPs) are wild plant and animal pro- ducts harvested from forests, such as wild fruits, vegetables, nuts, edi- ble roots, honey, palm leaves, medicinal plants, poisons and bush meat. Millions of people – especially those living in rural areas in de- veloping countries – collect these products daily, and many regard selling them as a means of earning a living. This Agrodok presents an overview of the major commercial wild plant products from Africa, the Caribbean and the Pacific. It explains their significance in traditional health care, social and ritual values, and forest conservation. It is designed to serve as a useful source of basic information for local forest dependent communities, especially those who harvest, process and market these products. We also hope that this Agrodok will help arouse the awareness of the potential of NTFPs among development organisations, local NGOs, government officials at local and regional level, and extension workers assisting local communities. Case studies from Cameroon, Ethiopia, Central and South Africa, the Pacific, Colombia and Suriname have been used to help illustrate the various important aspects of commercial NTFP harvesting.

  • Valuation of Ecosystem Services: Paradox Or Pandora’S Box for Decision-Makers?
    One Ecosystem 2: e14808 doi: 10.3897/oneeco.2.e14808 Research Article Valuation of ecosystem services: paradox or Pandora’s box for decision-makers? Maria Nijnik‡‡, David Miller ‡ The James Hutton Institute, Aberdeen, United Kingdom Corresponding author: Maria Nijnik ([email protected]) Academic editor: Stoyan Nedkov Received: 30 Jun 2017 | Accepted: 15 Sep 2017 | Published: 09 Oct 2017 Citation: Nijnik M, Miller D (2017) Valuation of ecosystem services: paradox or Pandora’s box for decision- makers? One Ecosystem 2: e14808. https://doi.org/10.3897/oneeco.2.e14808 Abstract The valuation of ecosystem services (ES) employs a range of methods. Based on a literature review and selected empirical examples, we consider major opportunities and challenges in ecosystem services valuation. We analyse when different valuation methods are appropriate and most useful. We demonstrate that mechanisms to capture benefits and costs are needed; and that the use of valuation should be incorporated more widely in decision-making. However, we argue that ecosystems are complex systems: neither the ecosystems or the services that they provide are a sum, but are an interrelated system of components. If a component vanishes the whole system may collapse. Therefore, critical natural capital management, in particular, cannot rely on monetary values; whilst the maintanance of the whole system should be considered. Monetary valuation of biodiversity and landscapes is also problematic because of their uniqueness and distinctiveness, a shortage of robust primary valuations, and numerous complexities and uncertainties. We conclude that mixed method and deliberative discourse techniques, as well as proper integration of research tools, should be more widely applied to help decision-makers and the public to understand and assess changes in ES.

  • The Elusive Quest for Valuation of Coastal and Marine Ecosystem Services
    water Review The Elusive Quest for Valuation of Coastal and Marine Ecosystem Services J. Walter Milon 1,* and Sergio Alvarez 2 1 Department of Economics, University of Central Florida, Orlando, FL 32816, USA 2 Rosen College of Hospitality Management, University of Central Florida, Orlando, FL 32816, USA * Correspondence: [email protected] Received: 3 June 2019; Accepted: 15 July 2019; Published: 22 July 2019 Abstract: 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.
