    The effect of violent conflict on calorie consumption and dietary quality in Iraq
    (2024) Parigi, Marta
    By combining 2012 Living Standard Measurement Survey cross-sectional survey responses and georeferenced conflict data, this study quantifies the effect of violent conflict on food security and dietary quality in Iraq. Specifically, it estimates the effect of physical insecurity on different food security dimensions, including caloric consumption and household dietary diversity. Because disrespecting war-related foreign national cemeteries is a war crime that discourages nearby fighting, instrumenting conflict intensity by the exogenous variation in distance between these sites and household place of residence addresses potential sources of bias. The instrumental variable analysis confirms the positive (negative) effect of conflict—deriving from state, non-state and one-sided violence (e.g., attacks by the Islamic State)—on per capita caloric consumption (household dietary diversity), which although counterintuitive is unsurprising given Iraq's relatively high-income levels and changes in dietary pattern. Given that the primary driver of conflict's positive effect on calories is increased consumption of carbohydrates and, to a lesser extent, saturated fat, these results suggest that in countries transitioning to Western-style diets, violent conflict may drive the population toward an unhealthier diet, contributing heavily to a growing national prevalence of nutrition-related non-communicable diseases.

    Investigating the environmental Kuznets curve between economic growth and chemical fertilizer surpluses in China: a provincial panel cointegration approach
    (2022) Yu, Xiaomin; Schweikert, Karsten; Doluschitz, Reiner
    This study investigated the relationship between fertilizer nitrogen (N) and phosphate (P) surpluses and economic development on the regional level in China. With a balanced panel dataset covering 30 provinces of mainland China from 1988 to 2019, we employed panel cointegrating polynomial regression (CPR) analysis using fully modified OLS (FM-OLS) estimators. Our results suggested that all provinces exhibit a long-run cointegrated relationship between fertilizer surpluses and real per capita gross regional product (GRP). A total of 22 provinces out of 30 showed a significant inverted U-shaped environmental Kuznets curve (EKC). Among those, 14 provinces are considered to have reached the peak and 8 provinces are considered to be before the peak. The group-mean turning points on the EKC are CNY 7022, CNY 9726, CNY 4697, CNY 3749, and CNY 5588 per capita GRP (1978 = 100) for the Northeast, Northcentral, Middle, and lower reaches of the Yangtze River, Southwest and Northwest China, respectively. The overall turning point of China is CNY 6705 per capita real gross domestic product (GDP), which was reached in circa 2012. This shows a general improvement of chemical fertilizer management in China. However, six provinces still exhibit linear growth in fertilizer surpluses when the economy grows. These regions are characterized by high cash-crop ratios and are mostly located along the southeast coast. Therefore, more effort and attention should be given to these regions to promote further fertilizer reduction. At the same time, nutrient use efficiencies should be improved, especially for cash crops such as fruit and vegetables.
