Abstract

Climate change and energy price fluctuations in Iran have considerable economic, social, and environmental consequences. Thus, in this study, the effects of climate change and energy shock on food security in Iran from 2004 to 2018 were investigated using a panel‐VAR model. The results indicate that climate change has a major contribution to the volatility of food prices. Also, among the climatic variables, the effect of temperature on food price volatilities is greater than that of precipitation. Furthermore, the results showed that any shock from energy price fluctuations has a positive effect on the price of agricultural commodities. Therefore, any attempt to decrease food insecurity in Iran's provinces should consider climate change. According to the above results, it is essential to identify regions vulnerable to food insecurity and adopt appropriate strategies to mitigate the effects of climate change on food insecurity. El cambio climático y las fluctuaciones del precio de la energía en Irán tienen consecuencias económicas, sociales y medioambientales considerables. En este estudio, por lo tanto, se investigaron los efectos del cambio climático y las crisis energéticas en la seguridad alimentaria en Irán desde 2004 hasta 2018, utilizando un modelo VAR de panel. Los resultados indican que el cambio climático contribuye en gran medida a la volatilidad de los precios de los alimentos. Además, entre las variables climáticas, el efecto de la temperatura sobre la volatilidad de los precios de los alimentos es mayor que el de las precipitaciones. Los resultados mostraron asimismo que cualquier perturbación de las fluctuaciones del precio de la energía tiene un efecto positivo en el precio de los productos agrícolas. Por lo tanto, cualquier intento de disminuir la inseguridad alimentaria en las provincias de Irán debe tener en cuenta el cambio climático. De acuerdo con estos resultados, es esencial identificar las regiones vulnerables a la inseguridad alimentaria y adoptar estrategias adecuadas para mitigar los efectos del cambio climático en la inseguridad alimentaria. 必ずしも経済的な要因が原因ではない大規模な都市化を経験してきたグローバル・サウスにおいては、都市部の貧困と脆弱性の動態はこれまでとは異なっている可能性がある。貧困を測定する従来の方法では、この問題の大きさと複雑さが見えてこない。本稿は、グローバル・サウスにおける都市貧困の測定と目標設定に対する代替方法を提案する。また、規範的な議論と実証的な事実のもと、貧困と脆弱性の相互関係、農村部と都市部のつながり、および分析における異なるカテゴリーとして都市部の貧困を特徴づける、その他の都市特有の問題を考慮する必要性を強調する。さらに、インドの最近の人口保健調査(Demographic and Health Survey:DHS)のデータを用いて、例証的な多次元指標を作成するため、本研究では、社会保障の欠如、貧困の罠、社会空間の断片化を表す新しい次元と指標を用いる。結果から、貧困の発生率は従来の推定値よりも高いことが明らかになった。
