The market for ecosystem services relevant to the Southern African context

1. Water regulation and supply

2. Carbon sequestration and maintenance

3. Natural landscapes (biodiversity) for recreation and bequest value.

Environmental and Social Cluster of the Expanded Public Works- Promoting Socio-Economic Development and Improved Livelihoods

1. Working for Water - manages invasive alien plants to enhance the sustainable use and conservation of our natural resources

2. Working for Wetlands - champions the protection, rehabilitation and sustainable use of South Africa's wetlands

3. Working on Fire - enhance the sustainability and protection of life, livelihoods, ecosystem services and natural processes through integrated fire management

4. Working for Woodlands - regain woodland composition, structure and function.

Page 4: The restoration of natural capital and the development of payments for ecosystem services in South Africa: An opportunity for sustainable natural resource management and use?

The Opportunities in the Water Sector

1. Yield (utilizable water),

2. Retention (maximize low flows),

3. Water quality (minimize the loss of top soil, siltation of water infrastructure, damage to water services and human health risks) and

4. Risk (minimize impacts of floods and droughts).

The Water Pricing Strategy - Clearing of Invasive Alien Plants (IAP’s)

• The full cost of control of certain IAP’s may be charged to affected water users.

•…. in consultation with affected stakeholders, … the control of IAPs is the best and most cost effective action possible to increase long term water security and availability.

•Once agreement is reached …, the total cost of control must be communicated to all affected stakeholder organisations. These costs may be supported by subsidy where available and appropriate.

Large-scale project scenario

•20, 000 hectares•417 people employed over 10 years•Total cost: $26 millionPotential annual earnings: @ $3 per credit $600,000@ $20 per credit $4 million

The Proviso•There is no free lunch. •Sellers must be capacitated to enter the market. •There is money to be made but it needs proper regulation.•A long term view•Transaction costs can be a deal breaker!

Impacts of Fire on Biodiversity, Ecosystem Processes and Services

• Sprouting – a large proportion of plants in fire-prone areas have the ability to sprout after fire,

• Serotiny – some plants (for example, proteas) hold their seeds in “fire-proof capsules” built from the remains of the flowers.

• Smoke-stimulated germination – the seeds of many plant species are stimulated to germinate by the chemical cocktails contained in smoke.

• Fire-stimulated flowering – many species are stimulated to flower, following fires, offering the best opportunity for seed production and germination of these plants.

• Flammability – “killing their neighbours”, and creating space for their own progeny to thrive.

• Dependence on fire-induced nutrient flushes - Some animals, such as Roan antelope, calve in the middle of the dry season, when green grass is scarce. The females need the protein flush that follows a fire to provide enough milk for their calves.

Two Major Impacts on Soil Movement and Related Ecosystem Services

• Fire (rotation and season)

• Unsustainable use (overgrazing and “nutrient mining”)

Conclusion

• There is potential for the development of a Payments for Ecosystem Services (PES) Market in South Africa

• The two most promising options at the moment are water regulation and carbon.

• It has the potential to have significant socio-economic benefits to the rural poor where up to 80% of the population are unemployed.

• Restoring Natural Capital and the development of PES could make significant contributions to the alleviation of poverty in developing countries all over the world.
