The book results from research carried out by the authors since 1999 on urban gardening collectives in Russia, then from the extension of this research towards collective urban gardening in France, with some investigations in other European Union Member States and Brazil. This research was carried out within the framework of Kazan University (currently, the Institute of Administration and Territorial Development of the Federal University of Kazan) and the French National Institute for Agricultural Research (INRA). It enabled the creation of an international research network entitled Sustainable Development of Cities: the Relationship between City-Dwellers and Nature. This research was developed with help from a three-year research contract (October 2009 - September 2012) with the GESSOL programme of the French Ministry of Ecology, on the theme of the use of urban and peri-urban soils for the sustainable development of cities. The final report of this research contract provides the basis for the book.
