Areas of research interest: non-market valuation, ecosystem services, watershed valuation

Project title: Ecological goods and services: clarifying property rights, assessing costs and benefits, and proposing incentive structures in watersheds across Canada (Fellow Water Research Group alumnus David Angus was also involved in this project.)

Description: Ryan is conducting his doctoral research as part of a collaborative research project under the supervision of Dr. Wolfgang Haider. The project seeks to investigate and propose community-compatible incentive structures that will best facilitate improvements in ecosystem services within four Canadian watersheds located in British Columbia, Ontario, and New Brunswick. To achieve this, the project researchers will: (i) examine the perspectives of landowners and the general public within and surrounding each watershed about property rights and responsibilities over ecosystem services; and (ii) conduct benefit-cost analyses of actions taken by landowners to improve ecosystem services in each watershed. A secondary objective is to investigate the accuracy of transferring the ecosystem service values between Canadian watersheds. The results of this analysis will be useful other communities in Canada interested in transferring the values estimated in our study to their watersheds for the purposes of establishing their own incentive structures for improving ecosystem services.

Profile: Ryan developed an interest in the outdoors, and in particular forests, while growing up in rural New Brunswick. He has a broad interest in incorporating non-market values into environmental management decisions. For example, he is interested in integrating the value of ecosystem services flowing from natural capital, such as forests, into the management of forest resources. To date, most of his research experience has dealt with non-market valuation in a watershed context.
