Many planning systems are currently locked into growth-dependence, encouraging market-led development which can widen social inequalities and produce adverse environmental outcomes. This accessible book introduces students to the debates around growth and planning and sets out the solutions to promote genuinely sustainable communities. It includes:¿ a positive proposal for reform of the planning system;¿ focused discussions from the UK and Europe providing lessons for future planning;¿ analysis of the challenges of implementing reform. Covering chapters on cooperatives, community land trusts, local economic development and community assets and infrastructure, as well as commoning, it provides a roadmap for planning system reform with social justice and sustainability at its heart.
