Optimal Design of Conservation Investments
Investment in Practice
|ECOLOGY & ECONOMICS:
We work on a range of problems that examine how
ecology and socioeconomic sciences can be integrated more effectively
to inform conservation strategies. This work spans theoretical and
empirical techniques and examines both biodiversity conservation and
the management of ecosystem services.

THE OPTIMAL DESIGN OF
Key references and links:
|We develop theoretical principles to inform
design. Some are intended to provoke discussion and critical thinking
within the conservation community. Others are intended to inform policy
and practice more directly. Focal questions for us here concern:
- where should conservation investments be
- what types of investment strategy work best in
ecological, social and economic context?
- when investing in a particular site, how should
population dynamics and ecosystem processes inform your conservation
Our recent work in this area has examined the relative effectiveness of
partial (e.g., through easements) acquisition of land for conservation,
leakage, informational asymmetries, and other issues of mechanism
design as it relates to agrienvironment schemes.

INVESTMENT IN PRACTICE
Key references and links:
|We are also building the evidence base regarding
investment practises on the ground. This work involves collaborators
including local (e.g., Yorkshire Wildlife Trust) and global
conservation NGOs (e.g., The Nature Conservancy) and a range of public
agencies (e.g., Natural England). Focal questions this time
- how much does conservation cost and how are
costs currently met by different organisations?
- how effectively are existing conservation
deployed given what we know about the distribution of biodiversity and
- what is the evidence that investing in
in a site improves the status of the species and ecosystems found there?
- what is the evidence that investments improve the ecosystem services provided by a site?

NATURAL RESOURCE MANAGEMENT
Key reference and links:
fisheries management provide one of the topic areas where
the integration of ecology and economics is arguably most established.
Again, we maintain active interests in this area. In particular, a
number of current projects focus on the design of spatial management
techniques (marine reserves and time-area closures) for managing
