Resumen
Descripción
Bangladesh’s brick kiln industry plays a critical role in supplying construction materials for rapid urbanization. However, the sector remains largely informal and weakly regulated, with widespread extraction of fertile topsoil and substantial emissions of particulate matter and black carbon. These practices raise growing concerns about long-term environmental degradation, agricultural productivity, and food security.
This policy brief summarizes new national-scale evidence on the impacts of brick kiln expansion on agricultural productivity in Bangladesh. Using satellite-based vegetation data covering more than two decades and a newly constructed geospatial inventory of brick kilns, the study provides causal estimates of how kiln establishment affects vegetation health and crop productivity over time.
