Abstract

For emerging countries such as Brazil, improved performance in the agricultural sector can be achieved by studies on the factors that have affected the performance and on economic perspectives relative to their internal structure and its relation with the external market. The present work aims to contribute with sustained economic expansion by studying strategies for expanding the energy supply in agribusiness. The characterization of specific energy consumption and energy indicators was performed considering a process of natural evolution, using logistic curves that describe the growth or evolution process. The specific energy consumption in agricultural activities was determined from data on the consumption of energy by machinery and equipments used in agricultural activities, as well as by establishing specific consumption indicators (ratio of energy consumed per unit produced) for each stage of production and by end-use. Nine crops and three herds were evaluated. In conclusions, the technology levels reached by the Brazilian agricultural sector have reflected on increased productivity and competitiveness in the international market with improvement in machines and equipments efficiency and operational capacity. In sugarcane culture, for example, the productivity increased 10% from 2009 to 2015. It has also been noticed a trend to reduce the use of low-power tractors and to increase the use of medium- to high-power tractors, which has also favored the productivity increase. The incorporation of new technologies tends to be more intense in the crops and herds that have an already established market. (AU)
