مدل های تکاملی تغییرات اقتصادی پایدار در برزیل: کشاورزی بدون توسعه، کاهش جنگل زدایی و سوخت های زیستی اتانول

This paper examines the historical drivers and barriers of three mitigation actions in Brazil: the expansion of no-till agriculture, reduction of deforestation, and increased displacement of gasoline with ethanol. The characteristics of these three economic changes align with evolutionary economic theories rather than neoclassical or environmental economics. Despite its cost-effectiveness, diffusion of no-till agriculture was contingent on social learning and flows of information within the agricultural regime. Brazil’s success in reducing deforestation rates was driven not by policies that changed the microeconomic calculation of farmers, but by command-and-control policies on deforestation enabled through landscape shifts. Brazil’s ethanol biofuels industry emerged due to both niche level innovation of ethanol production systems and pure-ethanol vehicles, and shifts at the landscape level that enabled mandated fuel blends, public procurement programmes, and public investment in R&D. These three economic changes correspond with the categories of reproduction, transformation and transition, respectively.
