On the geography of development

Monitoring Local Development
from outer space.

Our mission is to promote interdisciplinary science for economic, social, and environmental sustainability. We integrate insights from development economics, spatial data science, and applied econometrics to understand and inform the process of sustainable development.

01 / THE RESEARCH QUESTIONS

Why do subnational regions follow different development paths?

Satellite observations reveal patterns. Spatial econometrics, causal inference, and machine learning help us investigate the forces behind them.

The QuaRCS Network is an international and interdisciplinary research network in Quantitative Regional and Computational Science.

Five connected research areas

  • Sustainable regional development
  • The geography of development
  • Regional growth and inequality
  • Spatial structural change
  • Spatial energy economics

NIGHTTIME LIGHTS

Map human activity

Explore the geography of nighttime lights and discover how economic activity is distributed across places.

Explore the map

CHANGE OVER TIME

Follow regional change

Compare luminosity across regions and over time. Start with a pattern, then ask what might explain it.

Explore the trends

POPULATION & PLACE

Put places in context

Explore population patterns alongside the geography of light to frame new questions about people and development.

02 / BEHIND THE RESEARCH

Economics meets
spatial data science.

I’m Carlos Mendez, Associate Professor of Development Economics at Nagoya University, Japan. My research aims to integrate development economics, spatial data science, and applied econometrics to understand and inform the process of sustainable development.

My current research

  • Geospatial inequality, poverty, and growth interactions
  • Geospatial big data analytics and impact evaluation
  • Regional infrastructure, natural disasters, and structural change

05 / THE OPEN CLASSROOM

Build your research toolkit.

Learn to map disparities, analyze regional change, and evaluate policy with practical tutorials in Python, R, and Stata. Work through the methods, then bring them to your own research.
