Workshop: Development of the New National Long-Term Grazing Capacity Norms

The Department of Agriculture identified the need for a new National Long Term Grazing Capacity Map. The current 1993 map has various shortcomings and did not provide values for the previous homeland areas. A national steering committee has been appointed to take the lead in developing a new Long Term Grazing Capacity Map for South Africa.

Workshop: Development of the New National Long-Term Grazing Capacity Norms

The Department of Agriculture identified the need for a new National Long Term Grazing Capacity Map. The current 1993 map has various shortcomings and did not provide values for the previous homeland areas. A national steering committee has been appointed to take the lead in developing a new Long Term Grazing Capacity Map for South Africa.

Background

Long term MODIS NDVI (vegetation index) values were used to produce the first draft map. A tree canopy cover layer was added to indicate areas of high tree canopy cover. On the last meeting of the steering committee it was decided to publish 9 provincial maps in stead of one national product.

Objective

In this workshop, grazing capacity experts from each province will have the opportunity to evaluate 3 different products from which they have to indicate the best values for their province. Delegates will be provided with the following maps:

  1. The 1993 map
  2. The 2007 MODIS derived map
  3. Province own grazing capacity map (if available)

The workshop will tend as a report back on these products and changes, and no discussions on methodology will be allowed.

The main objective is to publish a product on a provincial level that is accepted by the province for use as Long Term Grazing Capacity Norms in the province.
