Uso do solo e produção de alimentos

Abstract

Entre 2005 e meados de 2008, o mundo foi surpreendido pelo aumento do preço dos cereais e dos alimentos em geral – o qual inverteu uma tendência continuada de descida dos preços reais ao longo das últimas quatro dé- cadas. Os preços registados em meados de 2008 estavam duas vezes e meia acima dos de 2005. Praticamente todos os produtos agrícolas bateram então os seus recordes históricos em matéria de preços.
