oa Botswana Notes & Records - Preliminary Land-Use and Land-Cover Mapping in the Upper Okavango Basin and Implications for the Okavango Delta

Volume 37, Issue 1
  • ISSN : 0525-5090



Image processing in the upper Okavango catchment resulted in ten generalised classes which may be used as base line data for monitoring future overall land-use/cover change assessments over the entire upper catchment. Specific work was undertaken using single images for more detailed land-use/cover mapping in a 10 km buffer along all tributaries of the upper Okavango in Angola and Namibia. In terms of the under-developed Angolan upper catchment there is relatively little land clearing at present, and impacts on water use and quality are expected to be minimal in the near future. This is a consequence of 20 years of civil war, while the return of refugees is being inhibited by the prevalence of land-mines. This area is likely to become more intensively used as Namibia attempts to develop greater food security.
