Environmental Economics


My research has been focused on the temporal and spatial aspects of environmental issues. I have recently worked on topics related to carbon emission, gray water footprint and choice of data scale in conservation studies.

Current and future projects are linked to climate change like the nexus water-crops-food safety, main drivers of the international evolution of negative environmental externalities, and regional growth and urban metabolism.

This paper analyzes the growth in gray water discharges between 1995-2009 using a structural decomposition analysis to isolate the main drivers of such increase. We show that domestic demand for food is the main driver of gray water changes in all countries, while relocation of industrial activities to developing nations has disproportionally transferred this burden from developed countries’ manufacturing industries.

A recurrent issue in conservation impact evaluation studies using GIS data is which scale of analysis to choose and what is the implication of such choice. Using a set of Monte Carlo experiments, we explore the modifiable areal unit problem in terms of scale and derive some recommendations to practitioners.

This paper proposes an integrated Input-Output-GIS model with health, energy and emissions extensions to estimate the impacts of different location choice of new power plants in Brazil.


Research in Progress

The paper traces the evolution of environmental externalities from American households’ consumption, both locally and in other nations. We identify the major drivers of shifts in regional spillovers, and the contribution of changes in international trade, global production chains and induced effects (those from household consumption) to the current trend.
