Sommario/riassunto

Urban Claims and the Right to the City explores how contested processes of urban development, and the rights of city dwellers, are understood and interpreted from the perspective of women and men working, in different ways, at the grassroots in Salvador da Bahia, Brazil, and London, UK. In doing so, it represents the grounded voices of authors whose work and lives mean that they engage, on a daily basis, with issues related to housing and spatial rights, and identity struggles around race, gender, disability, sexuality, citizenship and class. Reivindicações Urbanas e o Direito à Cidade investiga como os processos de desenvolvimento urbano em disputa e os direitos de moradores das cidades são compreendidos e interpretados por mulheres e homens que trabalham, de maneiras diferentes, nas bases populares de Salvador da Bahia, no Brasil, e de Londres, no Reino Unido. Ao fazê-lo, o livro representa vozes situadas de autores cujos trabalhos e vidas estão cotidianamente engajados em questões relacionadas aos direitos à moradia e ao espaço, e em lutas pautadas por identidades de raça, gênero, deficiência, sexualidade, cidadania e classe social.
