National Estuarine Monitoring Programme

What is the estuarine monitoring programme ?

The Department of Water and Sanitation established the National Estuarine Monitoring Programme, NEsMP, in 2008. The purpose of NEsMP is the monitoring of water quality, physico-chemical and biological aspects for determining long-term trends and changes in the condition of South African estuaries. The NEsMP coordinates national monitoring efforts and provides support in the form of sampling equipment, training, data management and information dissemination, while collaborating institutions collect physico-chemical data and water samples.

Estuary Tiers Legal framework :

NEsMP tiers of monitoring activity :

The NEsMP assesses South African estuaries at three levels of intensity:

  1. Tier 1 – collection of basic abiotic data
  2. Tier 2 - collection of more detailed abiotic data in line with reserve determination
  3. Tier 3 - event-driven monitoring to support management intervention in response to factors such as fish kills, pollution incidents and development pressure

NEsMP works with :

  • iSimangaliso Wetland Park
  • Ezemvelo / KZN Wildlife
  • Lower Tugela Biodiversity
  • Eden District Municipality
  • SANParks
  • Lower Breede River Conservancy Trust
