This study for WWF-Australia provides a global review and summary of the literature on the economic value of marine turtles. It also estimates the value of provisioning services and non-use values provided by marine turtles in the Asia-Pacific — a region characterised by the highest diversity of marine turtles, gravest threats and ongoing population decline.

Luke conducted an economic valuation of ecosystem services provided by the marine environment of the Cook Islands. This study was part of the Cook Islands Ridge to Reef (R2R) project, funded by the Global Environment Facility (GEF) in partnership with the Cook Islands Government with support from the United Nations Development Program (UNDP). The report describes, quantifies and, where possible, estimates the economic value of the Cook Islands’ marine and coastal resources. The key marine ecosystem services that are assessed in detail are: subsistence and commercial fishing; trochus; pearls; sand and coral aggregate; seabed minerals; coastal protection; tourism; recreation; and existence values related to marine biodiversity.

Luke recently published an update of the Ecosystem Services Valuation Database (ESVD) in collaboration with the Foundation for Sustainable Development (FSD) and Scotlands Rural College (SRUC). This update was funded by the UK Department for the Environment, Food and Rural Affairs (Defra). The ESVD now contains 4,042 records on the economic value of ecosystem services. This data is drawn from 693 studies. The report provides an overview of the economic value of 23 ecosystem services from 15 biomes standardised in International dollars per hectare per year.

Luke recently published an article in the journal Marine Policy on the global costs and benefits of expanding marine protected areas. Marine ecosystems and the services they provide contribute greatly to human well-being but are becoming degraded in many areas around the world. The expansion of Marine Protected Areas (MPAs) has been advanced as a potential solution to this problem but their economic feasibility has hardly been studied. We conduct an economic assessment of the costs and benefits of six scenarios for the global expansion of MPAs. The analysis is conducted at a high spatial resolution, allowing the estimated costs and benefits to reflect the ecological and economic characteristics and context of each MPA and marine ecosystem. The results show that the global benefits of expanding MPAs exceed their costs by a factor 1.4–2.7 depending on the location and extent of MPA expansion. Targeting protection towards pristine areas with high biodiversity yields higher net returns than focusing on areas with low biodiversity or areas that have experienced high human impact.

As part of the current revision process of the UN Statistics System of Environmental-Economic Accounting (SEEA), Luke authored a background paper for the Expert Meeting on Ecosystem Valuation in the context of Natural Capital Accounting organised by the German Federal Agency for Nature Conservation (BfN) in Bonn. The paper provides an overview of the environmental economics literature on the value of ecosystem services. During the past 30+ years, the discipline of environmental economics has attempted to produce information on the economic value of ecosystem services, i.e. their contribution to human wellbeing. This body of knowledge now comprises thousands of studies covering all regions of the world and all ecosystem services. This information may potentially be used as input into ecosystem service accounts and represents an important resource for the implementation of SEEA.

Luke authored a toolkit on environmental economic methods for marine ecosystem management for the GEF Large Marine Ecosystems Learning Exchange and Resource Network (GEF LME:LEARN) project. GEF LME:LEARN is a GEF-UNDP-IOC/UNESCO project designed to improve global ecosystem-based governance of Large Marine Ecosystems (LMEs) and their coasts by generating knowledge, building capacity, harnessing public and private partners and supporting south-to-south learning and north-to-south learning.

The purpose of this toolkit is to show how environmental economic methods can be used to produce information to support decision-making in the context of LME, Marine Protected Areas (MPA), Integrated Coastal Management (ICM), Marine Spatial Planning (MSP) and climate change adaptation. Specifically, it is designed to help a broad audience of practitioners, managers, government officials, private sector managers, NGOs, and statisticians to understand the available environmental economic tools and how the information generated can be used to inform the decisions that they make.

Luke published an article in the journal Ecosystem Services on the economic value of forests in regulating landslide risk. The role of forests in regulating landslide risks is well established but estimates of the economic value of this ecosystem service are limited. In order to incorporate the role of forests for landslide risk mitigation in spatial planning and other decision-making contexts, there is a need for spatially explicit information regarding the value of this service. The paper develops a methodological framework to combine bio-physical modelling of natural hazard risk and socio-economic exposure in a predictive model to estimate and map of the economic value of forest regulation of landslides. This method is applied in a case study of Adjara Autonomous Republic of Georgia to examine alternative scenarios for forest management and associated land cover change. The approach produces credible spatially explicit results to inform policy decisions regarding investment in forest management; and has the potential for replication in other data scarce regions.

Luke co-authored a report for WWF on the current state-of-the-art in ecosystem service-economy modelling and research. The report also identifies what new modelling and analyses are needed to fill key knowledge gaps and deliver evidence on the potential global socio-economic impacts of future changes in biodiversity and ecosystem services.

Luke co-authored a guidance manual on economic valuation of marine and coastal ecosystem services. The purpose of this guidance manual is to show how the value of marine and coastal ecosystem services can be estimated and used to support decisions about the use and management of marine ecosystems. It is designed to help a broad audience of conservation managers, government officials, private sector managers, NGOs, and statisticians to understand and apply the available economic methods for valuing marine and coastal ecosystem services to inform the decisions that they make. To this end, the manual provides: 1. A simple but technical introduction to the economic valuation methods that are applicable to marine and coastal ecosystem services; 2. An explanation of the limitations of each method and potential uncertainties; and 3. Examples of the use in the Pacific Island Countries and Territories (PICTs).

Luke co-authored five studies on the economic value of coastal and marine resources in the South Pacific as part of the Marine and Coastal Biodiversity Management in Pacific Island Countries (MACBIO) project. The studies are for Fiji, Kiribati, Solomon Islands, Tonga and Vanuatu; and assess the economic value of subsistence fishing, commercial fisheries, mineral and aggregate mining, tourism, coastal protection, carbon sequestration, and research and education.
