4.1.1. Drought
With improved understanding of southern hemisphere climate systems,
international meteorological services are increasingly able to
predict droughts. However, drought warnings will never be perfect,
partly because the effects of drought are never uniform, and partly
because droughts usually occur over a longer period of time.
Forecasting is mainly the task of the Weather Bureau. However,
forecasts are also available from international bodies and academic
institutions. Government and the private sector both have a role
to play in providing forecasts and advice to farmers. It is small
farmers who will mainly benefit from government's efforts, since
the large scale commercial farm sector has the ability to obtain
information elsewhere.
For droughts it is expected that the lead agency will be the national
Department of Agriculture, which will be the first government
body to initiate any preventative and reactive approaches to mitigating
the effects of predicted or actual drought.
The Department of Agriculture would also provide disaster management
support in cases of floods, veld fires, locust outbreaks, hail,
windstorms and tornadoes. Drought relief in the past has predominantly
been in the form of subsidies to meet the financial losses of
the white commercial farming sector and its creditors.
Prevention and preparedness
Working against drought in the long-term
- The Department of Agriculture has recognised that in the long-term
the reduction of the effects of drought is the best way to mitigate
against the negative impacts. Regular droughts are a normal part
of the climate in South Africa, where there is exceptionally high
variability in rainfall and temperatures associated with the normally
dry climate. Droughts cannot be prevented, so the farming community
has to accept variability and adapt to it as a normal part of
farm management.
- Recognising that the state cannot continue to bail out farmers
like it did in the past with subsidies,more proactive approaches
are now being taken or are being proposed for the agricultural
sector. In conjunction with this policy drive, the Department
of Agriculture is working towards establishing a better way of
co-ordinating drought response and relief. A proposal to establish
a national drought management centre is being investigated.
- The Minister of Agriculture has set up a task team to develop
a new policy on drought. Under the new policy initiative, government's
support for disasters will focus mainly on indirect intervention
through the promotion and facilitation of self reliant strategies
so that farmers take mitigating action to reduce the effects of
drought, both on the environment and on farm incomes. Some of
the proactive ways in which the Department of Agriculture is likely
to take preventative or proactive measure against drought are:
- Developing a national drought management plan that involves other
national departments, such as the Department of Water Affairs
and Forestry, and also the provincial and local governments.
- Improving the Early Warning System, through developing close collaboration
with the Weather Bureau and monitoring systems established by
Department of Water Affairs and Forestry, and through constantly
improved crop and forage forecasting (see below).
- Improving and developing a communication and information strategy
that is linked with communities, which provides farmers not only
with forecasts, but also with farming advice appropriate to the
best available forecasts in each province.
- Investigating and developing financial incentives, such as using
taxation mechanisms to encourage farmers and other communities
to save after good seasons to provide farm income after poor seasons,
and possibly targeting subsidised insurance to emerging farmers.
- Developing with Department of Water Affairs and Forestry a water
demand management strategy for the rural sector.
- Promoting better land-use management and conservation practices
through the extension services in the public and private sector.
- Where necessary, providing expertise and management capacity for
rural public works programmes to ensure that these promote "drought-proofing"
and water-harvesting in the rural environment, such as through
conservation works or afforestry.
Preparing for and responding to drought
A wide number of measures are required in response to drought.
Typical measures that the Department of Agriculture is taking
include:
- Improving information for early warning. Data that should be collected
and disseminated regularly by the Department of Agriculture include:
- National crop forecasting. This is necessary for good market information
for traders, as well as for our partners in the SADC who import
South African grain when available. The Department of Agriculture
is making adjustments to improve crop information now that the
marketing boards no longer exist to provide the information. Forecasts
should be presented to the public within statistical probabilities,
since they will never be completely accurate.
- Crop condition and forecasts in former homelands. Crop failures
provide warning that incomes will fall in an area, and alert other
departments, notably Health, Welfare and Public Works, that nutrition
and income support may be necessary.
- Condition of grazing lands, livestock and the access of livestock
to water.
- Satellite data (greenness indexes, etc) with comparisons from
previous years.
- Similarly, the Departments of Agriculture will gain useful information
from other participants in the early warning system, on weather,
forecasts (rainfall and temperature, stress days), dam and river
levels, etc.
- Ensuring with the cooperation of Department of Water Affairs and
Forestry and the SANDF that supplies of water are secured in poorer
and deep rural areas before the drought hits.
- Mobilising other state resources, to cushion or reduce the impact
of drought, through:
- Mobilising the support of provincial and local governments, particularly
in the most drought prone areas. Provincial departments of agriculture
have the major task in providing appropriate advice to farmers
through their extension services.
- Preparing a communication strategy and advice for farmers and
other communities on how to deal with the drought.
- Mobilising the resources of non-governmental organisations, community-basd
organisations and the private sector in assisting with relief
efforts, particularly in poorer areas.
- Coordinating with the emergency services and committees of organised
farmers, such as the SA Agricultural Union and the National African
Farmers Union.
Points of debate and key questions
- Should the Department of Agriculture (or provincial departments
of agriculture?) be the lead agent for drought disaster management,
and if so, who else should be the other key institutions working
with them?
- What aspects of disaster management should be dealt with by the
Department of Agriculture and provincial departments of agriculture,
and who should be involved for instance in response, and recovery?
What further proactive measures can the Department of Agriculture
take?
- What are the major obstacles to the proposed new approach to drought
management by the Ministry of Agriculture?
- What avenues should be pursued in conveying drought warnings as
early as possible?
- Which people should ensure that all people know the forecasts,
and that adequate advice is offered, and distributed widely?
- Are there institutions and mechanisms already in place that can
be used for this, but have not been used adequately in the past,
or do we need to create new ones?
- How best can one utilise civic or community based structures for
drought management?
- What is the best role of district and local councils in this regard?
Water management
While the national Department of Agriculture is regarded as the
national lead agency for drought-related aspects of disaster management,
the Department of Water Affairs and Forestry is the national lead
agency for most water-related aspects of disaster management.
This may sound like a contradiction in terms, but it is not.
The most relevant drought-related field of jurisdiction of the
Department of Agriculture, as far as disaster management is concerned,
is rain-fed agriculture. This mostly concerns dry-land crop farming
and also extensive stock farming. While these do contain their
particular aspects of water management, which are primarily handled
by Department of Agriculture, water management has a much broader
scope than rain-fed agriculture. The Department of Water Affairs
and Forestry is the national lead agency for this broader water
management. The Department of Water Affairs and Forestry's area
of rsponsibility includes, among other things, water resource
and infrastructure management to serve the urban sector, the rural
domestic sector and also irrigated agriculture at large.
South Africa is a relatively arid country - the average rainfall
is 40% less than the annual world average rainfall. The rainfall
that we do receive is distributed unevenly - some areas receiving
most rainfall and others hardly any. In addition, we face growing
demands for water from our natural water availability. Given these
factors - and the fact that water is essential to sustain all
forms of life - water management is a major area of concern as
far as disaster management is concerned.
Because it takes years, and often decades to plan for and implement
water management schemes - both on the supply and the demand side
- water management must receive continuous attention. This is
especially true during times of relative plenty, when we must
make provision for the cyclical periods of water scarcity. These
cyclical periods of water scarcity are inevitable in South Africa
but their exact timing, intensity and duration are less certain.
Examples of water supply schemes are, for instance, the establishment
of water retention structures, interbasin transfer schemes, water
distribution systems, etc. An example of a water demand management
scheme is the establishment of a national water and energy conservation
ethic.
Experience has proven that it is futile to base water management
schemes on the frequencies and intensities of droughts. Droughts,
by nature, differ vastly, depending on aspects such as rainfall
characteristics, moisture conditions before the drought, etc.
It often occurs that the rainfall during a season is adequate
to produce bumper crops, but that the run-off generated by these
rains does not substantially improve the water situation in our
hydrological systems, leading to so-called hydrological drought
conditions. In other words, there is enough rain for the crops,
but not enough going into our water supply systems, Effective
and efficient water management requires a continuous evaluation
and re-evaluation of areas of expected water scarcity. It requires
that projects are commissioned in good time to limit vulnerability
with regard to water.
South Africa faces a looming water shortage early in the next
century. The only way to address this problem is a continuous
focus on balanced water management practices. In this regard the
unbalanced water-management legacy left by the pre-1994 government
poses major disaster management problems. Some of the major water
management problems are the following:
- Department of Water Affairs and Forestry's focus in the past was
almost exclusively on the supply side of water management.
- The supply-side (water availability) focus of water management
was limited to specific regions, excluding, for instance, the
previous homeland areas. This left vast areas and millions of
people without even moderately stabilised water resources and
basic supply infrastructures.
- Even where a degree of basic water-supply infrastructure has been
supplied in these previously marginalised communities, the communities
have not taken ownership of this infrastructure, for various reasons.
This has led to inadequate maintenance and operations practices.
- The demand-side of water management was left to the second and
third tiers of government (province and local), basically without
incentives from the national level for these authorities to effect
water conservation. All efforts to foster a conservation ethic
thus have to start from scratch.
Thus although the water availability (supply side) seems quite
good in some areas and sectors - mainly the few metropolitan areas
- the present water management situation has a number of serious
deficiencies that the disaster management fraternity must take
note of. It will take many years, even decades, to iron out these
problems, but even after that, it is envisaged that the disaster
management fraternity will have to stay closely involved with
water management.
Prevention and preparedness
The new Department of Water Affairs and Forestry, established
after the 1994 elections, has been exerting itself to address
deficiencies in existing water management approaches, in order
to effect sustainable water management practices, for instance:
- Department of Water Affairs and Forestry published a White Paper
on Water Supply and Sanitation towards the end of 1994, inter
alia, describing the endeavours required to bring at least 25
litres of clean water per person per day to the majority of our
people at a walking distance of not more than 200 meters;
- Since 1994 Department of Water Affairs and Forestry, with a mandate
from Cabinet, has been actively involved in establishing water
supply and sanitation infrastructure in the rural areas. To date
water supply infrastructure to serve between one and two million
people in the rural areas has been supplied. This excludes work
done under the Municipal Infrastructure Programme, which focuses
on urban dwellers and which is also going ahead full steam.
- On the demand-management side, Department of Water Affairs and
Forestry has various programmes running to further water conservation
practices. Very prominent is the "Working for Water Programme"
with various thrusts, e.g. the programme to eradicate alien invasive
vegetation in water-stressed catchments for which more than 8
000 additional jobs have so far been created.
- Our Water Law is being revised substantially to afford holistic
management of water as an indivisible substance in the whole of
the hydrological cycle, and also to effect equity with regard
to water availability and its use;
- The recently passed Water Services Act to identifies the responsibilities
of the various tiers of government and other role-players with
regard to the provision of water and sanitation services. This
will streamline the functioning of the complex hierarchy of institutions
involved with water management, also with regard to emergency
measures and water restrictions.
Responding to water shortages
In terms of the Constitution, water supply and sanitation are
primary functions of local authorities. These authorities must
therefore take ownership of their water supply systems and channel
adequate means towards their operation and maintenance.
Department of Water Affairs and Forestry has a regional office
in each of the nine provinces, which can assist local authorities
and relevant institutions if they should encounter serious water
management problems.
It is essential, however, that partnerships be developed in the
water management field. It is trusted that the provincial disaster
management focal points will largely contribute towards these
endeavours, guided by the proposed National disaster management
Centre.

4.1.2 Floods and Dam Failures
Floods are natural phenomena that occur at irregular intervals
anywhere in our drainage system of rivers and streams. Although
floods cannot be regarded as unexpected, where and when they will
strike is highly unpredictable. The scale of the floods also varies
widely, from minor flashes to major events.
Flood management in general involves a wide range of measures
which can be classified either as structural and non-structural:
Structural measures are physical measures, such as the construction
of flood attenuation dams, river draining works such as levees
and urban stormwater systems to control flood run-off and river
flows.
Non-structural measures entail for instance the introduction and
enforcement of sensible land-use practices on floodplains, promulgation
of dam safety legislation and regulations, furthering flood preparedness
and contingency planning, instituting flood warning systems, etc.
Non-structural measures are aimed mainly at changing patterns
of behaviour.
Local authorities often find that the flood management guidelines
and directives from the national and provincial spheres are not
forceful enough. At present these guidelines and directives are
contained in the Water Act (No 54 of 1956) and in various Provincial
Ordinances. By incorporating these into local bye-laws, local
authorities can establish sensible flood management practices.
Department of Water Affairs and Forestry is the lead agency on
the national level with regard to the physical management of rivers
(the management of water-related matters). For this reason Department
of Water Affairs and Forestry is also expected to be the lead
agency on a national level with regard to floods and dam failures.
However, flood management, and especially non-structural flood
management, is much more of a people issue than a water management
issue. It would therefore make much more sense to have a multi-sectoral,
interdepartmental, integrating body for overall flood management.
Department of Water Affairs and Forestry could feed its largely
technical flood management information into such an integrating
institution. The integrating institution could then link this
technical information with other important information (demographic,
social, etc.) and ensure that it is made available in a useful
form to target audiences. Department of Water Affairs and Forestry
could then limit its input to only water-related aspects.
Other non-water-related issues such as town-planning and building
norms and standards, disaster management contingency planning,
etc. would be handled by other bodies or departments with the
necessary expertise in those fields.
Prevention and preparedness
By and large disasters resulting from floods can be prevented,
as most flood damage occurs because of poor planning, and the
settlement of people in high risk areas on floodplains.
- Although many components of a flood management policy may already
exist, they are not clearly described in a single document. There
is also not a single lead agency dealing with flood management
issues on the national level. The responsibility of a national
lead agency will be, for instance, to ensure that a National Flood
Management Policy is developed and maintained as part of the envisaged
National disaster management Structure. Some of the main elements
of the policy could include, for instance:
- Clear identification of the flood management roles and responsibilities
of national, provincial and local government, catchment authorities,
the private sector (e.g. the insurance industry), individuals
and communities.
- Arranging for a structure of financial assistance to further pre-emptive
flood management practices.
- Providing for the development and enforcement of standard or "default"
norms and practices for how floodplains should be used.
- Arranging for the development and maintenance of a communication
strategy.
- Measures to safeguard the public against loss of life and property
by means of dam safety legislation and flood control guidelines
have been developed by Department of Water Affairs and Forestry.
- The Department has direct access to the best available river flow
data, which include water levels during flood events and current
and planned releases from dams. Monitoring of rainfall and runoff
with the purpose of forecasting flood flow and issuing warnings
exists in only a few places in South Africa. The Department of
Water Affairs and Forestry maintains such a system in the Vaal-Orange
River system of dams, the Ladysmith Local Council has such a system
in the Klip River and the Sandton Local Council monitors the Jukskei
River where it passes through Alexandra. Department of Water Affairs
and Forestry and the Weather Bureau have developed a pilot project
called the "Integrated Vaal River Forecasting System" to facilitate
better flood management in the Vaal River Basin.
- At present Department of Water Affairs and Forestry is busy with
initiatives on our most important rivers to collect and access
up-to-the-minute data with the aid of the newest satellite and
cellphone technology. Presently, there are 46 observation stations,
and the intention is to expand these to 59 to give even wider
coverage.
- The Department is also empowered to build government water works
for the specific purpose of flood control. The Water Act, 1956
empowers the Department of Water Affairs and Forestry to subsidise
the cost of repairing water works damaged by floods.
Responding to floods
Regional or wide-area floods
- A danger situation typically escalates over days and weeks.
- Department of Water Affairs and Forestry monitors river flows
and dam levels, but the density and sophistication of monitoring
networks available, differ vastly from catchment area to catchment
area.
- The Weather Bureau monitors rainfall on a national basis and routinely
issues warnings of expected heavy falls. These forecasts are crucial
for flood warnings where rivers are full.
- Department of Water Affairs and Forestry issues warnings where
it has information of floods escalating. This is done by press
releases and, in a few cases, directly to specific large communities
at risk. A major shortcoming is the absence of an institution
into which Department of Water Affairs and Forestry can feed its
observations and flood forecasts. There is a need for an institution
which can take Department of Water Affairs and Forestry's technical
information and transform it into a form which is useful and meaningful
to the various target audiences usually involved, and which can
direct relevant information and warnings to the respective audiences.
- In the majority of our rivers, flood warnings from the national
level are not possible, largely due to a lack of information at
that level. Communities themselves and regional organisations
such as irrigation boards, normally play an important role in
preparedness and flood warnings. The levels of preparedness of
communities vary vastly, even in one catchment area.
- Depending on the size of the flood escalating, adjacent local
authorities, the province/s, SAPS, the regional component of the
SANDF and the national lead agency will be alerted by either a
specific local authority or regional organisation. In the past
the SAPS and, especially, SANDF helicopters played a crucial role
in rescue operations.
- The following critical services are often interrupted by floods
and require emergency reinstatement:
- Communication systems
- Potable (drinkable) water supply
- Access along selected streets and roads
- Power supply
- Sewers
- Past floods have shown the need for specialist relief teams to
be available to communities during and after floods. These include
typically:
- A co-ordinator with special skills and authority to establish
order and to determine the correct priorities.
- Medical personnel with emergency supplies to provide (additional)
treatment facilities. It appears as if the Medical Corps of the
Defense Force is ideally equipped to fulfill this function.
- Specially trained social workers to deal with the morale of the
affected community.
- Civil engineers to oversee the reinstatement of public buildings,
schools, water supplies, sanitation, streets and roads, and electrical
engineers to oversee the reinstatement of the power supply.
Flash floods at the local level
- Local authorities have the responsibility to monitor and warn
inhabitants against flash floods and inform the relevant provincial
and national governments.
- Local authorities also have the responsibility to mobilise their
emergency services and volunteer institutions or organisations.
- If the situation is beyond the capacity of the local government
to manage, it can call on the assistance of the SAPS, SANDF and
other bodies that can provide physical support in dealing with
victims and conducting search and rescue missions.
- The local authority is also responsible for mobilising temporary
housing resources from the Department of Housing at the Provincial
and National levels, the SANDF, NGOs or the private sector.
- Finally, the local authority has the task of establishing the
extent of damage, and the number of victims.
Dam Failures
- Dam failures occur for a number of reasons. They can either happen
during a flood, when the mass of water spilling over the dam wall
erodes the structure and causes failure. Or there can be a so-called
"sunny-day" failure, when the dam wall fails due to structural
instability. This can be caused by, for example, earthquakes or
deterioration of materials over time.
- For many large dams, emergency preparedness plans exist. Such
plans are statutory requirements for new category II and III dams.
The owner of the dam has the duty to initiate these plans. Local
authorities and Civil Protection Organisations downstream should
play an important role in establishing and maintaining such a
plan. The requirements with regard to emergency preparedness plans
should probably be expanded to also make provision for existing
dams.
- The onus is on the owner of the dam to alert people and communities
downstream of a dam-break developing, in accordance with the emergency
preparedness plan. He/she must also continuously monitor the situation
and inform people downstream of developments. From there onwards
the situation could be dealt with in the same way as a natural
flood event.
Points of debate and key questions
- Who should be the lead agency dealing with floods, and how should
this lead agency involve provincial and local governments in both
long-term and short-term strategies for flood disaster management?
- Is everything being done to ensure that flood potential is closely
monitored, and then, local warnings are provided in a useful format
for people to respond?
- What are the main issues and concerns arising from flood disaster
management with existing systems in place?
- Who else at the national level should the lead agency involve
in preventative measures against floods, and how?
- How best can communities be involved in flood disaster management?

4.1.3 Fire Hazards
The value of property destroyed by fire is increasing in South
Africa. The annual estimate for fire losses is approaching R1000
million. Fire disasters may be caused by a single fire that spreads
from the point of origin - such as buildings - or they may be
the secondary result of another disaster such as a storm or earthquake
that starts fires in numerous locations simultaneously.
Prevention and preparedness
- Within the urban environment fires are prevented through legislation
such as the National Buildings Regulations and municipal by-laws.
Other measures include public education and codes of practice
issued by the SABS.
- Fire fighting, rescue, and emergency medical operations are covered
by the Fire Brigade Services Act, 1987. The Act empowers the Premier
of each province to take extraordinary measures to allow a fire
brigade service to effectively deal with incidents. This is an
important operational provision that can take effect in the early
stages of an incident, before it is formally declared a disaster.
- The Fire Brigade Services Act, 1987, confers a wide range of powers
on a fire fighter. These include the authority to enter premises,
close streets, obtain assistance from the public, and even to
demolish buildings.
- Fire brigade services normally deal with hazardous materials incidents.
They are involved in the safety and prevention aspects during
inspections and building plan approval as well as the mitigation
phase during incidents. Fire fighters receive training in dealing
with a wide range of hazardous material incidents. Larger departments
have large databases at their disposal as well as protective clothing,
HAZMAT equipment and chemical monitoring equipment.
- Fire brigade services are also the agency that responds to disasters
caused by road traffic accidents, collapsed buildings and similar
large-scale incidents.
- The current Fire Brigade Act needs to be applied to expand the
pool of volunteers that can be used as 'reservist' in cases of
emergency. Local government can use the services of NGOs and other
public sector institutions to train these reservists. This provision
in the Act has not been sufficiently exploited.
- There are efforts to establish a National Incident Data System,
which is able to provide quick data and statistics on fires and
hazardous materials incidents. This data system should be linked
to a National Incident Management System and should eventually
form part of information collated by the IDMC.
- In the case of predicting potential weather conditions for fire
hazards, such as veld or forest fires, the Weather Bureau plays
a critical role in advising the public, agricultural communities,
and the forestry sector by giving early warnings.
Responding to fires
In the case of fires, the first people that are likely to respond
to a fire disaster are the emergency services units of a local
authority. However, it is clear that most of the well-equipped
emergency services are based in urban centres, and these are suited
to deal with a range of fire-related incidents such as structural
fire-fighting, aviation, marine, wildfires, and so on. In rural
areas, however, emergency services are weak, and often communication
with these areas is difficult. In responding to fires, the local
authority does carry out certain actions, and these involve:
- Mobilising rapid response teams, with some provinces including
a combined medical services unit. In towns where these services
have been provided in combination, they have been found to be
more effective.
- Calling on intergovernmental co-operation in cases of major disaster.
The main role-players in this case are likely to be the ambulance
department, Department of Water Affairs and Forestry, Environmental
Affairs, university laboratories, SAPS, traffic authorities, SABC,
Hospitals, State veterinary services and provincial health departments.
- In cases that involve rural areas, local authorities have to work
with the Department of Agriculture and Forestry sectors to deal
with particular fire hazards.
Points of debate and key questions
- What are national roles in fire disaster management, and who should
be the key agency?
- What are the main constraints in dealing with fire hazards?
- What are the main preventative measures that can be taken and
who should be involved?
- How should fire brigade services be funded nationally? Is there
a role for the private sector?
- Have efforts been made to ensure that the Forestry and Agriculture
Departments co-operate in their responses to veld fires?
