 Landscape-scale analysis of ecosystem risk and returns: A new tool for ICZMJeremy Hills, Margaret Carlisle, Martin Le Tissier, David Muir and Caroline Robinson Marine Policy, 2009, vol. 33, issue 6, 887-900 Abstract: Management of the coastal zone often focuses on "islands" of high value ecosystems, in terms of economic value or conservation. However, integrated management requires landscape-level analysis of all ecosystem values. The biodiversity portfolio analysis (BPA) method is derived from the logic used in share (equity) portfolio management in terms of balancing within a portfolio the returns with the risks. Optimising the returns from a share portfolio, or a suite of ecosystems in a landscape, is dependent on the relationship between the units in terms of risk and return. Three case studies are then presented to test the applicability of the BPA method at the international (North West Europe), regional (Durham Heritage Coast, UK) and local (part of South Uist, Outer Hebrides, UK) spatial scale. The Biodiversity Portfolio Analysis for NW Europe showed that risk and return were highly correlated in the studied Member States. The ranking of risk and return, with the highest first, was Ireland > UK > France=Netherlands > Belgium. For these Member States the risks to ecosystem service provision were positively correlated with GNI (r=0.97, P Keywords: Integrated; Coastal; Zone; Management; Coastal; management; Environmental; economics; Stakeholders (search for similar items in EconPapers) Downloads: (external link) Related works: Export reference: BibTeX RIS (EndNote, ProCite, RefMan) HTML/Text Persistent link: https://EconPapers.repec.org/RePEc:eee:marpol:v:33:y:2009:i:6:p:887-900 Access Statistics for this article Marine Policy is currently edited by Eddie Brown More articles in Marine Policy from Elsevier |
