About

I study agricultural adaptation to water scarcity through economics, geospatial analysis, and decision-support modeling.

My work focuses on groundwater sustainability, irrigation systems, crop choice, land-use transitions, and the economic feasibility of agricultural adaptation strategies.

Karthik Ramaswamy

Professional Bio

I am an agricultural and resource economist specializing in hydro-economic modeling, irrigation systems, groundwater sustainability, and geospatial agricultural analysis. My research examines how agricultural producers and landscapes adapt to water scarcity through changes in irrigation technology, crop selection, land use, and investment decisions.

I currently work as a postdoctoral researcher at the Nelson Institute Center for Sustainability and the Global Environment at the University of Wisconsin–Madison. My current research focuses on groundwater-dependent agricultural regions, especially the U.S. High Plains Aquifer, where long-term aquifer depletion is reshaping irrigation capacity, crop production, and land-use decisions.

My work integrates agricultural economics, optimization, crop-water relationships, remote sensing, GIS, and county-level agricultural datasets to evaluate policy and management strategies for water-limited agricultural systems.

Research Interests

My research interests sit at the intersection of agricultural economics, water resources, spatial analysis, and applied decision support.

Education and Background

My training combines agricultural economics, irrigation systems, groundwater management, spatial analysis, and applied modeling.

Ph.D.

Agricultural Economics

Oklahoma State University. My doctoral research focused on the economics of groundwater management, irrigation decision-making, and agricultural water use.

Current

Postdoctoral Researcher

University of Wisconsin–Madison, Nelson Institute Center for Sustainability and the Global Environment.

Focus

Applied agricultural and environmental systems research

My current work uses geospatial data, optimization, economic modeling, and decision-support tools to study adaptation pathways for groundwater-dependent agriculture.

Methods and Technical Expertise

I use quantitative, spatial, and computational methods to study agricultural water systems.

Economic Modeling

Crop budgets, net returns, investment analysis, net present value, policy scenarios, and agricultural production economics.

Optimization

Mathematical programming and hydro-economic optimization for crop choice, irrigation capacity, groundwater use, and land-use transitions.

Geospatial Analysis

GIS, remote sensing, county-level agricultural data, crop maps, irrigation datasets, climate data, and groundwater layers.

Decision-support Tools

Applied tools using Excel/VBA, Python, ArcGIS, and GAMS to support irrigation investment and agricultural adaptation decisions.
