Scott Butcher
Restoration & Community Development
Scott's areas of expertise can be traced back to growing up on the edges of the Avon-Heathcote Estuary in Christchurch, New Zealand. This led to work as a research assistant monitoring the nesting of endemic braided river birds, which resulted in work that became critical in achieving a Conservation Order for the Rangitata River.

Scott's has also worked within regional and urban parks in Christchurch, Auckland and Sydney involving project management of the construction of park infrastructure across a wide range of projects. Contract management also formed a core element of these roles and managing urban parks maintenance contracts as well as ecological restoration contracts across coastal dune, wetland and bush ecosystems.

As a result of more than 2 years of volunteering in the Solomon Islands and working for the United Nations Development Program (UNDP) and the World Bank, Scotts skills have broadened to include working with indigenous communities and sub-national government to strengthen resilience in the face of climate, disaster and environmental risk. He also worked on collaboratively developing simple yet effective planning process that have allowed communities and provincial governments to identify, plan, and implement their development priorities. The area of climate change resilience, risk integration and the role of effective planning processes is something that he aims to explore further through his postgraduate research.
