Custos de privação em desastres naturais no Brasil: estudo de caso das commodities de arroz nas enchentes do Rio Grande do Sul

Abstract

Deprivation costs were defined as the economic and social losses resulting from the temporary or permanent unavailability of essential goods. This study aimed to analyze the deprivation costs arising from hydrological natural disasters, focusing on the floods that affected rice production in the state of Rio Grande do Sul, Brazil. The choice of this topic was justified by the relevance of rice in the diet of Brazilians and by the country’s dependence on production from Rio Grande do Sul, which accounts for approximately 70% of national output. The main objective was to understand the influence of intense rainfall on rice production and prices, applying economic concepts related to deprivation costs. The adopted methodology consisted of a case study focusing on the floods that occurred in Rio Grande do Sul and their impacts on the rice harvest. The research addressed variables related to rainfall, productivity, production costs, and the recovery capacity of affected properties, using economic concepts and quantitative methods to understand the effects of climatic events on the production chain. In addition to the productive and economic analysis, the study examined the resilience of the rice supply chain in the face of hydrological disasters, identifying structural and logistical aspects that contributed to the increase in deprivation costs. Thus, the research sought to understand the relationship between climatic events and production costs, highlighting the challenges faced by the rice sector in Rio Grande do Sul and the importance of policies aimed at risk mitigation and strengthening food security.
