Katrina Mullan studies the drivers and impacts of land use change, with a current focus on Brazil, China, and the Northwest United States. She uses household surveys and remote sensing data to conduct quantitative empirical analyses, often within interdisciplinary teams. Dr. Mullan has published in journals such as Environmental and Resource Economics, the Review of Environmental Economics and Policy, and World Development. She joined the University of Montana in 2012 to teach courses in Environmental Economics, Econometrics and Microeconomics. Dr. Mullan has a PhD in Environment and Development Economics from Cambridge University, and previously advised on environmental policy for the UK government and the European Environment Agency.

I study how people make decisions about land use and how their choices affect the environment. I primarily use quantitative empirical methods, relying particularly on spatially-referenced panel datasets. This research falls within the following overlapping themes:
Agricultural expansion into tropical forests
Smallholder decisions about use of land and other resources have important environmental implications both globally (e.g. climate change, biodiversity loss) and locally (e.g. erosion, water reliability). My research examines the potential implications of agricultural conversion and intensification for poverty alleviation and ecosystem service provision. I focus on three specific questions:
(1) What are the impacts of deforestation on smallholder incomes and local ecosystem services?
(2) How are smallholder land use decisions affected by changes in household wealth, market development, climate and local ecosystem services?
(3) How effective are alternative policy mechanisms for forest protection?
Environment and migration
I study the impacts of environmental conditions on migration decisions, and the outcomes for land use change. This includes effects of resource depletion on migration to new frontiers in the Brazilian Amazon, effects of climate-related natural disasters on rural-urban migration in Thailand, and how presence of natural amenities such as public lands, lakes and rivers or mountains influences population and housing growth in the northwest US. Key research questions include:
(1) How do the influences of environmental conditions interact with other drivers of migration to determine who migrates and where they go?
(2) What are the environmental consquences of population growth and associated land use change in ecologically sensitive regions?
Improving the sustainability of food, energy and water systems requires understanding how they are connected. I study how land use choices link these systems, including how deforestation for agriculture alters farm productivity via impacts on rainfall and streamflow, and how rural energy provision affects agricultural practices. Students interested in this area of research can apply to the UM BRIDGES graduate training program.
Responses to environmental risks
Health impacts of natural disasters or environmental pollutants depend on how individuals or families understand and respond to the risks they face. I study the actions of people faced with indoor air pollution, wildfires, droughts or floods, to assess the relative importance of information, attitudes and financial or technical constraints in determing behavioral responses to health risks.
