Agricultura de base ecológica em sistemas urbanos: potencialidades, limitações e experiências.

Urban Farm DB summary

This review compiles ecological principles for urban agriculture—crop diversity, organic and mineral-based fertilizers, and non-toxic pest and disease management—and describes international examples such as diversified plots in Austria and the "organoponico" system in Cuba. It surveys Brazilian experiences from pioneering ecological urban agriculture in Belo Horizonte, Minas Gerais, to later programs in Campinas (São Paulo) and Natal (Rio Grande do Norte), as well as initiatives in Rio de Janeiro, the São Paulo municipal urban agriculture program, and Brasília, presenting the rationale, alternatives, and constraints of ecologically based crop management in urban agriculture.
