Title: THE WORKING FOR WATER PROGRAM
1THE WORKING FOR WATER PROGRAM

- South Africa
2AIS The damage and threat
- 1 000 introduced plant species became
naturalised, 200 are invasive - use 3.3 billion cubic metres more water than
indigenous vegetation - waste 7 of our water resources
- Cost South Africa R600 million a year over 20
years - Loss of Biodiversity Up to a 1/4 of RSAs plant
species - Loss of life, damage to land and property
through high intensity fires.
3The Government of South Africa's Department of
Water Affairs and Forestry created a conservation
program called Working for Water in 1995
4 MISSION The Working for Water programme will
control invading alien species, to optimise the
potential use of natural resources, through a
process of economic empowerment and
transformation. In doing this the programme will
leave a legacy of social equity and legislative,
institutional and technical capacity.
5Objectives
- Enhance water security
- Improve ecological integrity
- Restore productive potential of the land
- Invest in marginal sectors to improve quality of
life - Develop economic benefits from wood land, water
and trained people
6Integrated approach
Clearing invading alien plants.
- Various Departments
- Research and Academic Institutes
- Partners/sponsors in the Private Sector
- International partners
Results
- More than 40 000 jobs were provided.
- Projects in all the provinces.
7Mechanical and Chemical Control
- Basal bark
- Hand pull
- Ring barking
- Frill
- Cut stump treatment
- Stem injection
8Bio ControlSavings of 20-30 could be
achieved if biocontrol methods are used for
woody species.
9Is biological control safe?
- Is only released once it has been proved as
sufficiently host-specific. - Tested and approved biocontrol agents do not
pose a threat to our own crops or indigenous
vegetation, or to those of neighbouring
countries. - No cases of changing their host plant affinities.
10Track record
Since 1913, 95 species of biocontrol agents have
been introduced into SA to control 48 weed
species. No unpredicted host switches have
occurred yet.
11Is biocontrol effective?
- do not completely exterminate populations of
their host plants - small populations of biocontrol agents that
persists will disperse onto re growth or
newly-emerged seedlings of the weed - sustainable control method
12Advantages of biocontrol
- environmentally friendly,
- self-perpetuating or self-sustaining
- cost-effective
- does not disturb the soil
- does not create large empty areas where other
invaders could establish. - allows natural vegetation of the area to recover
gradually in the shelter of the dying weeds. - all levels of biocontrol improve the chances for
rehabilitation of the cleared area
13Legislation
- The Agricultural Pests Act
- The Conservation of Agricultural Resources Act
- National Environment Management Act
- Environment Conservation Act
- Draft National Biological Diversity Act
- National Water Act
- National Veld and Fire Act
14Agricultural Pests Act, 1983 (Act No. 36 of 1983)
- The main purpose is to prevent the introduction
of agricultural pests and organisms associated
with agriculture. - Control the importation of biocontrol agents
- The Directorates Plant Health (DPH) the NPPO,
- South African Agricultural Quarantine
Inspection Services (SAAFQIS)
15Official International trade
- Controlled by the NPPO
- Agricultural Pests Act, 1983 (Act No. 36 of 1983)
- National and International regulations, standards
and agreements
16Plant import
- Plants imported on permit system
- Declared weeds and invaders are prohibited
- Risk assessment show potential new weeds
- Weeds and potential weeds are regarded as pests
as per IPPC definition
17Import of biological control agents
- Biocontrol imported per permit
- Background info is required
- Panel of experts review application, do risk
assessment - Approved organism imported
- Species specificity tests done
- Host specificity test plus other research
18Biocontrol import
- Application for release to NPPO
- NPPO review plus sent to panel of experts
- Release can continue and biocontrol agent are
mass reared for implementation
19CONSERVATION OF AGRICULTURAL RESOURCES ACT (CARA)
Act 43 of 1983, Conservation of Agricultural
Resources Act, 1983 was proclaimed to provide for
control over the utilisation of the natural
agricultural resources of the Republic in order
to promote the conservation of the soil, the
water sources and the vegetation and the
combating of weeds and invader plants and for
matters connected therewith. In March 2001
regulation 15 and 16, dealing specifically with
declared weeds and invader plants, were
promulgated in the Government Gazette Number
22166, thus bringing the number of declared weeds
and plants to a total of 198.
20REGULATION 15 - CATEGORY 1
15A -Deals with combating Category 1
plants Declared weeds Importation and
cultivation is prohibited
21CATEGORY 2
15B - Deals with the combating of Category 2
plants. These plants have a commercial or
utility value, and are only allowed to occur
under certain conditions and with special
permission.
22CATEGORY 3
15C - Deals with the combating of Category 3
plants. These are plants with an ornamental
value, and are allowed to be kept growing if
under controlled circumstances and no more
trading or propagating is allowed
23CONTROL MEASURES
- 15D - Deals with the designation of biological
control reserves for the breeding of biological
control agents. -
- 15E - The different methods for control are
stated here. The need for follow-up actions is
emphasised . Any action taken to control
category 1, 2, and 3 plants shall be executed
with caution and in a manner that will cause the
least damage to the environment.

27The Biological Control Implementation (BCI)
programme in WfW
Initiation and structure
- National BCI officer (Penny Gillespie) PPRI,
1999 - Six regional BCI officers WfW
- Ensure all available BC agents distributed
throughout range - Facilitate incorporation of BC into WfW clearing
programmes
28Distribution of biocontrol agents
- Researchers
- Brief BCI officers on biology of agent
- Supply them with starter culture
- Supply info and photos for agent brochure
- Involved with releases
- Detailed post-release monitoring
- BCI officers
- Mass-rear agents
- Release agents in co-operation with researchers
- Monitor for establishment in co-operation with
researchers - Produce agent brochures
29Sources of insects for redistribution
- 1. Mass-rearing in regional BCI centres
- On potted plants in shade houses
- In insectaries on cut stems
- 2. Field collecting, once insects has
established on biocontrol reserve sites - 3. Insects laying their eggs on immature fruit or
seeds of large woody trees cannot be
mass-reared in lab field-collected seasonally
30Protection of released agents
- Legislation recognises biocontrol, protects
effective BC sites - Allows important BC agent nurseries to be
registered as biocontrol reserves protected
from clearing - Undertaking signed between land user and DoA
31Lessons learnt
- Importance of co-operation between researchers
and BCI officers - Selection criteria for regional BCI officers
skills in field technical information transfer - Value of large agent releases
