Optimal allocation of marine areas for ecosystem services

Fisher interactions with sea lions

Behavioural incentives to decrease land clearing

Using a spatial optimisation model, we evaluate how marine management will influence the provision of different marine ecosystem services in Chile. We consider food provision, scenic beauty, and biological diversity.

In Peru and Chile, South American sea lions (Otaria flavescens) compete with fishers for fish and damage fishing nets.

In this research we 1) identify the key concerns fishers have regarding their interactions with sea lions, and 2) quantify the economic impacts of sea lions on fishers’ income.

We evaluate land holder preferences for financial and non-financial incentives to participate in conservation programs in Queensland, Australia.

Preferences for marine energy in Chile

Climate and economic tipping points

What is the value of information in social-ecological systems?

Globally, there has been an increase in the development of marine renewable-energy technology and installations. Due to it's large coastline, Chile provides an ideal location to develop marine energy. We use best-worst scaling to assess the preferences of the Chilean public for the characteristics of potential marine energy installations. The characteristics that we assessed included: environmental impacts, aesthetic qualities, and cost. We use latent class analysis to understand heterogeneity in preferences among different socio-economic groups.

We evaluate how smooth and abrupt changes in climate affect agricultural land use decisions in the UK with and without a policy response to mitigate climate impacts. We represent abrupt climate change as a switching off of the Atlantic Meridional Overturning Circulation (AMOC) and our policy response as irrigation.

We use value of information methods to examine where research will deliver the most important information for environmental management.

Problems caused by choice inconsistency

How do we value complex marine ecosystems?

Economic value of saltmarsh ecosystem services

This analysis presents novel insight into a non-novel conclusion: interpretation of models that account for heterogeneity in error variance (scale) can be misleading if researchers do not appreciate the implications of reported parameter estimates being conflated with scale effects.

To accurately capture how the public values marine area management, we need valuation approaches that can accommodate the complexity of environmental systems and human interaction with them.
