SSS12.7

The editors of Land Degradation and Development Currently, several aspects of land degradation and resilience are at the centre of hot debates: How much do no-till technologies contribute to sustainable soil management? Can reclaimed land be converted to arable land? Do we have strong evidence of the land restoration potential of regenerative agriculture? Does land degradation lead to large carbon storage in sediment, hence a feedback on global warming? What is the optimal level of soil organic matter? Is biochar addition enhancing or curbing soil erosion? Does the revival of ancient land management techniques induce soil erosion? Can 137Cs efficiently be used to measure soil-loss rates? Researchers will present evidence and defend their opinion concerning either side of these and other ongoing debates. After debating, the authors will be invited to publish their (opinion) papers in a special issue of “Land Degradation and Development”. This approach will direct auditors and readers to evidence that contributes to the debates. The session will provide suggestions on how the research community may assist in resolving such very important questions of land and soil degradation.
