Addressing oil spills and agricultural productivity. Evidence of pollution in Nigeria

Laburpena

This paper examines how the pollution generated by oil operations in Nigeria can affect agricultural total factor productivity. I analyze oil spills, which are the main ecological disaster in Nigeria and lead to major environmental, economic, and social problems. Following a consumer-producer household framework, and applying a difference-and-difference approach, I estimate an agricultural production function. I find that farmers located less than 10 kilometers from oil spills suffer a relative reduction in agricultural output of around 2.73%. I also examine alternative mechanisms and find that oil-spill pollution can explain my results. I detect less owner-occupied land and a drop in labor income in urban areas close to oil spills, which could also be explained by a decrease in the labor productivity component. This study highlights an externality through which the oil industry affects living conditions in rural areas and stresses the importance of clean-up in areas close to oil spills.
