ON COMMON GROUND is a collection of original essays, written by 42 scholars and practitioners from a dozen countries, tracing the growth and diversification of the international community land trust movement. A community land trust (CLT) is a transformative strategy of community-led development on community-owned land that has taken root in the Global North and is now spreading to the Global South. CLTs produce and preserve affordably priced homes, community gardens, retail spaces, and a variety of neighborhood facilities – all developed under the guidance of the people who live nearby; all managed to remain permanently affordable for people of modest means.
