This handbook offers epistemologically and ontologically important personal accounts of academic and professional researchers having long-term intensive, comprehensive and ethnographic fieldwork in various social settings and versatile regional contexts across the globe. The accounts are cross-disciplinary including anthropology, sociology, geography, political sciences, gender studies, forestry and environmental studies, economics, and international relations. They are also trans-regional, covering the globe including South Asia, Southeast Asia, Africa, Europe, Latin America and North America. The book offers a comprehensive portrait of multifaceted challenges that social researchers experience while doing fieldwork in various social settings. The accounts provide both challenges of doing fieldwork in the 21st century and the ways how to address/redress them in the field by complying with the codes of ethics, and the politics of fieldwork. Readers will benefit from the handbook by understanding methodological issues from both disciplinary relevance and regional specificity across time and spaces.
