Modern methods of agriculture have led to cities growing out of control and reducing the available agricultural land, threatening the sustainability of our food system. The previous mutually sustaining relationships of animals, humans and the land have been lost with the progress of industry. The Smartcity - an ecological symbiosis between nature, society and the built form - is the innovative response to contemporary problems from one of the world's leading urban design and architectural thinkers. Addressing the problems of unchecked city growth, the idea of the Smartcity questions whether we could begin to live once again from first principles, focusing in on the inhabitants of the city. The holistic construct of the Smartcity is developed through a series of international case studies, some commissioned by government organisations, others speculative and polemic. Reframing the way people think about urban green space and the evolution of cities, CJ Lim and Ed Liu explore how the reintegration of agriculture in urban environments can cultivate new spatial practices and social cohesion in addition to food for our tables. Representing an emerging architectural voice in matters of environmental and social sustainability, Smartcities and Eco-warriors is a long overdue treatment of the subject from a designer's perspective, and is essential reading for practitioners and students in the fields of architecture, urban planning, environmental engineering, landscape design, agriculture and sociology. An inspiration to government agencies and NGOs dealing with climate change, it also resonates with anyone concerned about cities, energy conservation and the future of food
