Though transformative change requires cross-sectoral solutions, many governments continue to budget and plan largely along sectoral lines. The thematic working papers in the Towards a More Equal City series highlight sectoral interventions that have proven effective in cities around the world, with a focus on struggling and emerging cities. They draw on the deep experience of the authors and focus on key sectors that highlight how cities are different today and why they need new solutions. They examine sanitation, water, transport, land management, the informal economy, energy, and housing.
