    This was a presentation at a Workshop on Development of an Interim Framework for the National Land Use Classification Standard, Methodology and Symbology for South Africa.  It shows why land use and land cover are not the same, why land use often cannot be determined from imagery alone, and why land use, zoning and planning are not the same.

    The role of urban agriculture in global food security is a topic of increasing discussion. Existing research on urban and peri-urban agriculture consists largely of case studies that frequently use disparate definitions of urban and peri-urban agriculture depending on the local context and study objectives.

    By increased rural-urban migration in many African countries, the assessment of changes in catchment hydrologic responses due to urbanization is critical for water resource planning and management. This paper assesses hydrological impacts of urbanization on two medium-sized Zimbabwean catchments (Mukuvisi and Marimba) for which changes in land cover by urbanization were determined through Landsat Thematic Mapper (TM) images for the years 1986, 1994 and 2008. Impact assessments were done through hydrological modeling by a topographically driven rainfall-runoff model (TOPMODEL).

    Nowadays it is necessary to process geographic data about landscape in a digital way. It is possible to analyse selected data and approach to decision and proposition-making process of landscaping based on analysis of these results. The LANDEP methodics provides us verified procedures of primary landscape structures assesment and landscaping. Digitalization of selected landscape elements increases processing efficiency, mainly for time reasons. Creation of complex landscape plans of cadastral areas at Slovakia should become a basic priority of every commune.
