Abstract

A maior parte dos estudos socioeconômicos que tratam das mudanças climáticas procura explicar qual é o custo associado a esse fenômeno, considerando os diferentes cenários propostos para o futuro. Tratando especificamente do setor agrícola, a literatura é diversificada e apresenta resultados distintos. Essas diferenças se devem, principalmente, aos métodos alternativos de análise, às condições climáticas tomadas como base, às previsões de crescimento econômico e aos cenários climáticos considerados. Neste artigo, procurou-se organizar essa literatura em duas abordagens principais. Uma delas procura entender o impacto sobre o setor agrícola, desconsiderando, ou apenas incluindo, implicitamente, as estratégias adaptativas; a segunda abordagem modela explicitamente a adaptação, analisando seu potencial de mitigar os efeitos negativos das mudanças climáticas. Concluiu-se que, mesmo havendo diferenças de entendimento sobre a forma de mensurar os impactos, a maior parte dos estudos prevê que as nações em desenvolvimento serão as mais afetadas negativamente pelos efeitos das mudanças climáticas globais......Most socioeconomic studies that address climate change aims to explain what is the cost associated with this phenomenon, considering the different scenarios proposed for the future. Taking account specifically the agricultural sector, the literature is quite diverse and presents different results. These differences are mainly due to alternative methods of analysis, climatic conditions, the economic growth outlooks, and climate scenarios used. In this paper I tried to summarize this literature into two major approaches. The first one aims to understand the impact on the agricultural sector, disregarding, or only implicitly including, the adaptive strategies; the second approach is able to model explicitly the adaptation, analyzing their potential to mitigate the negative effects of climate change. It was concluded that, even with differences of understanding on how to measure the impacts, most studies predicts that developing countries will be the most negatively affected by global climate change effects
