Goals and scope of the special issueLand use is at the centre of political and ethical dispute all over the world. How these disputes are conducted depends, to a certain extent, on scientific policy advice. Knowledge related to land rights, food sovereignty, environmental governance, societal and cultural values, and social and human behaviour, among others, represent the frame conditions, well analysed data the content for a qualified debate. Accordingly, cross-fertilization between social and natural sciences and with local stakeholders is critical to produce the knowledge needed to spur transformation (Jahn et al., 2012). In this special issue we aim at:• encouraging transdisciplinary co-production of knowledge on land use in sustainability research • generating original theoretical and methodological insights on the rapid and profound societal and environmental processes currently taking place at Latin American frontiers, and beyond • contributing to an inventive research agenda for transformative research on land use at extractive and agrarian frontiers.Two assumptions guide our reflection:• True transdisciplinarity implies trusting that each source of knowledge involved has a significant role to play in generating the collective insights needed to construct sustainable futures.• We need innovative arenas, where scientific/lay, Western/non-Western, quantitative/qualitative approaches fruitfully interact, to produce hybrid, socially, politically and ecologically conscious research results.With our Special Issue we, therefore, want to foster integrative approaches from a broad spectrum of social science perspectives, ranging from critical geography, agrarian/gender/cultural studies, political sciences, sociology to anthropology and history. We wish to incorporate qualitative, empirical and exploratory methods, which address the societal root causes, processes and implications of land use change. Indeed, they are invaluable in performing actor-, network-, and policy analyses, and providing critical insights into the motivations, perceptions, preferences, and decision-making of societal actors in relation to nature, ecosystem services and land use/land cover (LULC) changes.
