OxTalks is Changing
Oxford Events, the new replacement for OxTalks, will launch on 16th March. From now until the launch of Oxford Events, new events cannot be published or edited on OxTalks while all existing records are migrated to the new platform. The existing OxTalks site will remain available to view during this period.
From 16th, Oxford Events will launch on a new website: events.ox.ac.uk, and event submissions will resume. You will need a Halo login to submit events. Full details are available on the Staff Gateway.
Land degradation – is it a cause for concern?
‘Land degradation’ is a general term that covers many forms of soil deterioration that results in poorer quality, less healthy soils. Its most important form is erosion by water (runoff) which is a global problem with well known ‘hotspots’ such as the Loess plateau in China, Ethiopia and Madagascar. The causes are usually a combination of government economic policy, unwise farming practices, vulnerable soils, sloping sites and rainfall. In Europe, predicted wetter winters and increase in frequency of intense rainfall in summer, increase the threat of erosion. Erosion does not generally impact our ability to grow food crops, but the off-site impacts are very costly: reservoir sedimentation, muddy flooding of properties, pollution of freshwater systems. Soil conservation measures are often linked to flood protection, but quite different approaches may be needed. Soil protection is poorly reflected in global legislation e.g. The Sustainability Goals, and off-site impacts are frequently ignored.
