The book is based on the multi-country collaborative research project Becoming a Young Farmer: Young People's Pathways into Farming in Four Countries (2017-2021). The four countries are: Canada, China, India, and Indonesia. It responds directly and concretely to concerns about the generational sustainability of smallholder farming worldwide- reflected in the current UN Decade of Family Farming. Most current research and literature center on why young people leave farming. The book draws on research that instead asks: "Given the constraints they face, how do (some) young people continue to pursue a (future) livelihood in farming?' The book uses the life-course perspective and privileges voices of young women and men farmers to show that movement away from farming such as time spent in education, migration and non-farm work do not exclude eventual farming futures. Analysing young people's diverse pathways of becoming a farmer illuminates the constraints they face, and their efforts to overcome them. The future shape of rural communities, and of the world's agriculture, will depend to a large extent on these and future generations of young people, their interest in and ability to acquire the needed resources for farming careers and livelihoods.This is an open access book.
