{"title":"Armed conflicts and household food insecurity: Effects and mechanisms","authors":"Wendata A. Kafando, Takeshi Sakurai","doi":"10.1111/agec.12814","DOIUrl":"10.1111/agec.12814","url":null,"abstract":"Despite extensive studies on the effects of armed conflict on household dietary diversity, food security, and nutritional outcomes, the underlying pathways remain underexplored. A better understanding of these mechanisms could unpack the subsequent effects of conflict-induced food insecurity and oft-reported nutritional shortcoming, as well as identify which policy interventions hold promise. We study the effects of terrorist violence in Burkina Faso on household dietary diversity, as proxied by food consumption scores (FCS), and investigate the underlying mechanisms. For this purpose, we combine nationally representative 5-years panel data on households with spatial conflict data. We find negative and significant effects of conflict intensity on household food consumption scores. The decline in household FCS is a result of significant decreased dietary diversity in both food production and purchases. Although households in rural areas partially offset these reductions by food assistance, those reliant solely on farming as livelihoods remain the most affected. Further investigations show evidence that per-capita farm income and food expenditure are pathways linking the intensity of armed conflict to reduced FCS in food purchases, whereas reduced dietary diversity in food production results from decline in crop production. Additional specification tests support our main findings, offering insights that can help policymakers faced with similar scaled-armed conflicts. For instance, conflict-sensitive interventions aimed at supporting crop production and farm income for affected households could effectively improve their dietary diversity and overall food security in a post-conflict environment.","PeriodicalId":50837,"journal":{"name":"Agricultural Economics","volume":null,"pages":null},"PeriodicalIF":4.1,"publicationDate":"2024-01-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/agec.12814","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139517700","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Devadason","doi":"10.1111/agec.12811","DOIUrl":"10.1111/agec.12811","url":null,"abstract":"This paper examines the diffusion of external (output and price) shocks to the Association of Southeast Asian Nations (ASEAN) through the agri-food trade channel for the 1990Q1 to 2020Q4 period. For that purpose, the study develops a Global Vector Autoregressive (GVAR) model to simulate the region's economic resilience (output, inflation, interest rate and exchange rate) from various external shocks. We find that the agri-food channel is relevant in the shock propagation to ASEAN. There are more pronounced output effects on ASEAN from global output shocks relative to regional output shocks channeled through agri-food trade. However, the macroeconomic responses of ASEAN to global price shocks are not uniform due to the different consumption intensities of oil and raw materials, with negative and positive output effects from oil price shocks and raw material price shocks, respectively. Overall, ASEAN is more vulnerable to oil price shocks than to raw material price shocks. Our results emphasize that the distributional impacts of the agri-food trade channel and the ASEAN region's ability to mitigate the effects of global shocks depend on the degree of trade linkages and the region's capacity to counter the demand contractions and supply disruptions. The findings suggest that ASEAN should be cautious about the global shocks penetrating through the agri-food channel to address its macroeconomic vulnerabilities and better manage its economic resiliency.","PeriodicalId":50837,"journal":{"name":"Agricultural Economics","volume":null,"pages":null},"PeriodicalIF":4.1,"publicationDate":"2023-12-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138954572","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Abay, Patrick Hatzenbuehler","doi":"10.1111/agec.12809","DOIUrl":"10.1111/agec.12809","url":null,"abstract":"This paper uses comprehensive and long time series monthly food price data and a panel dyadic regression framework to evaluate the impact of the COVID-19 pandemic and associated policy responses on spatial market integration across a diverse set of food items in Nigeria. The empirical results reveal several important insights. First, we show that a significant slowdown in the speed of adjustment and price transmission occurred during the pandemic. For some food items, the speed of adjustment and, by implication, spatial market integration weakened by two- to-threefold after the outbreak of the pandemic. The effect was especially pronounced for perishable food items. Second, lockdown measures and the spread of the pandemic triggered additional dispersion in market prices across markets. For example, lockdown measures were associated with a 5%–10% reduction in the speed of readjustment toward long-term equilibrium. Third, additional underlying attributes of markets, including lack of access to digital infrastructure and distance between markets, exacerbated impacts associated with the pandemic. For instance, access to Internet service reduced the slowdown in the speed of adjustment caused by the pandemic, but longer distances between market pairs induced greater slowdown in the speed of price transmission. Our findings offer important insights for revitalizing the efficiency of food markets affected by the pandemic. The heterogenous impacts of the pandemic across value chains and markets reinforce the need to properly target post-pandemic recovery interventions and investments. Finally, we offer some insights to reduce the vulnerability of food and market systems to disruptions in future pandemics or similar phenomena that inhibit food marketing and trade.","PeriodicalId":50837,"journal":{"name":"Agricultural Economics","volume":null,"pages":null},"PeriodicalIF":4.1,"publicationDate":"2023-11-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/agec.12809","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135037675","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
