Ecosystem Services

Ecosystem services are the benefits that humans obtain from ecosystems. The vast majority of these services are usually taken for granted, but they are essential for human wellbeing. There is a growing interest in ecosystem services for two main reasons:

  • to provide sustainable resources for human wellbeing that will meet the Millennium Development Goals and
  • to provide incentives for ecosystem conservation

medium

The Millennium Ecosystem Assessment divided ecosystem services into four categories and this has provided a framework for ongoing studies of ecosystem services:

  • provisioning services (e.g. water, food, drugs and genetic resources)
  • regulating services (e.g. flood attenuation, herbivory, pest control and pollination)
  • supporting services (e.g. primary production, nutrient cycling) and
  • cultural services (e.g. recreational, spiritual and cultural benefits)

What we do

The Biodiversity Research, Information and Monitoring Division's programme on ecosystem services focuses on two main issues:

  • How does biodiversity contribute to ecosystem services?
  • What benefits will the focus on ecosystem services provide for biodiversity conservation?

Food marketOne of the initial thrusts in ecosystem services is that it provides benefits for agriculture. Food security is a key issue all over the world and agriculture is one of the main sources of land transformation, with concomitant impacts on biodiversity. Studies of ecosystem services in agricultural landscapes can explore the relationship between biodiversity conservation, sustainable land use and food security.

Insect pollination is essential in the production of several agricultural crops. SANBI is leading the South African component of the GEF/UNEP/FAO Global Pollination Project - a project which is examining the conservation and sustainable management of pollinators for agriculture. Related to this work is the Honeybee Forage Project, of particular importance in South Africa where agriculture relies heavily on the managed honeybee - which requires adequate year-round forage for colony health.

SANBI has also recently become engaged in the "Networks" project, a collaboration with the University of Exeter, in the UK and Université Pierre et Marie Curie, in France. The Networks project is funded by the EU through the International Research Staff Exchange Scheme (IRSES). The project uses ecological networks to investigate how indigenous vegetation provides pollination and pest control services to mango farms in Limpopo Province.  

The work of the Ecosystem Services team can be summarised as follows:

  • Crop pollination services in South Africa
  • Honeybee forage
  • Natural enemies in the agro-ecosystem
  • Insect diversity, ecosystem services and land management practices
  • Rangeland productivity
  • Valuation of pollination ecosystem services
  • Operational model for classifying ecosystem services
