Climate change could deepen poverty in developing countries due to the adverse climatic events, such as heat waves, drought and heavy rains. Urban workers in Bangladesh, Mexico and Zambia were found to be the most at risk, as the cost of food drives them into poverty.
Southeast Asia showed a projected 40% increase in the magnitude of the worst rainfall; central Africa showed a projected 1000% increase in the magnitude of the worst heat waves; and the Mediterranean showed a projected 60% increase in the worst drought.
A statistical analysis was used to determine grain productivity shocks that would correspond in the magnitude to the climate extremes, and then the economic impact of the supply shock was determined by the researchers from Purdue University, Washington.
