Abstract

O artigo avalia, com base na construcao de um modelo insumo-produto ecologico, a pegada hidrica nacional e a balanca comercial de agua virtual no Brasil para o ano 2015. Verificou-se que a pegada hidrica do pais alcanca 22.012 hm3/ano de agua virtual, o que equivale a um consumo per-capita de 107,66 m3/ano ou 294,97 litros/dia. Na balanca comercial, verificou-se, em funcao dos setores da agropecuaria e da agroindustria, um saldo exportador liquido de 8.542 hm3/ano de agua virtual que abastece a cada ano 79,33 milhoes de habitantes no mundo. Contudo, frente a escassez de agua global, para proteger o meio ambiente de forma sustentavel, e necessario criar um mercado formal de agua virtual.

巴西经济的水足迹和虚拟水贸易平衡：投入产出分析

本文基于生态投入产品模型的构建，评估了2015年巴西国家水力足迹和虚拟水的商业平衡。研究发现，该国的水足迹达到22012 hm3/年的虚拟水，相当于人均消耗107.66 m3/年或294.97升/天。在贸易平衡中，虚拟水的净出口余额为8542 hm3/年，每年供应世界7933万居民，具体取决于农牧业和农工业部门。然而，鉴于全球缺水，为了可持续地保护环境，有必要创建一个正式的虚拟水市场。

期刊介绍： The journal Economia Aplicada (Brazilian Journal of Applied Economics) is a quarterly publication of the Dept. of Economics of the Faculty of Economics, Business and Accounting of the University of São Paulo at Ribeirão Preto (FEA-RP/USP). It was first published in 1997 by the Dept. of Economics of FEA-USP and by FIPE, with the primary concern of filling an editorial gap in Brazil. The Journal"s interest is to publish solely scientific papers on applied economics. Nowadays it has the same goal. Its focus is to publish papers with economic analysis applied to specific problems of interest either to public or private sector, especially with quantitative results bringing theory and reality closer.
