Résumé
This book originated in a workshop organised in La Paz (Bolivia) in December 2008, as part of the Franco-Bolivian ANR-EQUECO programme, with the aim of reflecting on socio-environmental changes in agriculture in the southern Andes over the last 1,000 years. Subsequently, as a result of international collaborations, including the Franco-Argentine ECOS programme, the editors invited other experts to contribute their work to these reflections. The authors of this book - archaeologists, anthropologists, geographers, geneticists, agronomists and ecologists - represent a balanced panel of human and biophysical sciences. All have direct and recent experience of the current or past reality of the societies and natural environment of the Southern Andes. Despite the diversity of their respective disciplines and perspectives, the authors have endeavoured to make their contributions accessible to a non-specialist audience, presenting tables and figures to facilitate understanding of the data and using a glossary to define, where necessary, certain technical or vernacular terms. The temporal scope of the book covers pre-Hispanic periods to the present, while geographically, it covers the southern altiplano and inter-Andean valleys of southern Bolivia, the puna and valleys of northwestern Argentina, and the contrasting regions of Chile.
