Three essays on irrigated agriculture in Brazil
type: CreativeWork
description: The Irrigation technology is an important tool capable of mitigating the adverse effects of climate change, ensuring the yields, raising agricultural productivity rates and increasing employment in rural areas, which generates income and raises food security. Despite its multiple benefits, irrigation adoption in Brazil is still low given the potential for incorporation of new arable land, making the effects of this technology on the production process underestimated and underexplored. The present thesis seeks to analyze the effect of irrigation adoption on important aspects of the Brazilian irrigated agriculture, such as the technical efficiency between irrigators and rain-fed producers; the effect of irrigation on grain supply and demand for productive factors; and added gross revenue from the adoption of irrigation technology. To achieve those goals, three chapters are developed: Irrigation, technical efficiency and farm size in Brazil; Irrigation effects on grain sector in the Brazilian Southeast: A short-run analysis; and The value of irrigation adoption in the Brazilian agriculture. The first chapter analyzes the effect of irrigation technology adoption on the technical efficiency of Brazilian agricultural establishments. The methodological approach combines the stochastic production frontier structure, taking into account the selection bias (Heckman's approach), with the entropy balancing technique. The results show that irrigation adoption contributes to increasing the technical efficiency of irrigators by 2.51 percentage points compared to rain-fed farmers, on average. The greatest effect is observed for the group of large farmers. In the second chapter, we analyze the effect of irrigation on the supply of grains and the demand for productive factors in the Southeast region of Brazil. A system of equations is estimated using the restricted quadratic profit function approach. The results point toward a positive effect on the supply of grains and demand for la…
