This text aims to summarize the state of scientific knowledge on drylands globe. It explores current stage understanding desertification as well its extent and possible solutions. The book argues that is one world's most pressing environmental problems it a global issue which accelerating. edition has been revised expanded include updated computer images desertification, fuller descriptions explanations issues concerned. Using detailed data physical chemical status soil degradation provided...
Abstract The Anthropocene is proposed as a new interval of geological time in which human influence on Earth and its record dominates over natural processes. A major challenge demarcating the that balance between human‐influenced processes varies spatial temporal scales owing to inherent variability both activities (as associated with culture modes development) drivers (e.g. tectonic activity sea level variation). Against this backdrop, we consider how geomorphology might contribute towards...

Abstract As part of a wider project investigating the palaeoenvironmental significance partially vegetated linear dunes in southwest Kalahari, data collected latter 1992 concerning dune movement and vegetation cover suggest that sediment transport is occurring on some surfaces, majority surface activity occurs crests upper slopes dunes. The limiting variables vary different parts dune. On interdunes lower primary variable available wind energy, while it cover. Ground by litter has much...

Environmental change poses risks to societies, including disrupting social and economic systems such as migration. At the same time, migration is an effective adaptation environmental other risks. We review novel science on interactions between migration, climate change. highlight emergent findings, how dominant flows of rural urban mean that populations are exposed new within destination areas requirement for sustainability. issue lack mobility a major limiting effectiveness strategy...

Abstract Using data from field studies in the Kalahari rangelands of Southern Africa, relationships between ‘scientific’ and ‘land user’ interpretations land degradation change nonequilibrium savanna ecosystems are explored. Scientific land‐user views often regarded as distinct, even opposed, knowledges. We contest that a more constructive view can be taken through concept hybrid knowledge, whereby value is attached to both approaches which useful meaningful assessment environmental change,...
