An updated drought plan is essential
Meteorological experts predict a high likelihood of the Southern African region getting belownormal rainfall by June thanks to El Niño. Indeed, the rainy season began later than usual.
But the SA Weather Service has indicated that while central and southwestern parts of the country may be drier, the northeastern region (which produces most of SA’s grain) is likely to have average rainfall.
Whatever the outcome, it is important for the government to reevaluate its drought response strategy. By definition, drought is the shortage of water due to low rainfall. Its effects are usually broadly felt and include poor crop harvests, higher food prices, deaths of people and livestock, more infectious disease such as cholera, unemployment, poor economic activity and possibly political unrest.
While wealthy countries are also prone to drought, famines are generally avoided because advanced economies have greater resilience through irrigation systems, robust water infrastructure (dams, groundwater, desalination), strong currencies and ample food reserves, secured from previous successful agricultural seasons.
SA’s drought management plan is based on the white paper on disaster management (1999), the Disaster Management Act (2002) and the National Drought Management Plan (2005). Most responsibility for addressing drought and its effects is given to the department of agriculture, with subsidiary roles for the Treasury and provincial and local government.
But a broader, multisectoral drought plan would go a long way in helping avoid problems associated with ad hoc (spontaneous) responses. The drought plan should be more specific when it comes to the ministries’ obligations so that these do not have to be negotiated in the middle of a crisis. It should comprise tasks to be performed before, during and after a drought, to build maximum resilience.
Droughts can be complex. They bring with them problems other than scarcity of water. So in crafting a comprehensive drought response it is important to take stock of all adverse effects on the country. At the earliest prediction the relevant government departments, including international relations, finance and diplomatic missions, should initiate negotiations for sizeable disbursement of humanitarian aid from multilateral institutions, nonprofit organisations and bilateral partners.
This will be necessary for as long as SA is still a developing nation. The Treasury’s rising debt burden means national financial resources have become more limited. It is thus difficult to provide an adequate cushion. Coordinating resources only when a drought’s worst effects become noticeable would be unfortunate. At that stage donors would have already been swarmed by other countries in the region also in need after being hit by El Niño conditions.
The department of health should have a high level of preparedness to prevent and quickly resolve outbreaks of diarrhoeal diseases such as cholera, even before a drought ensues. The department of local government may need to assess the competence of metros and municipalities to ration water in affected communities. If “water-shedding” is communicated beforehand and last no more than a few hours it can result in water savings that can help reservoirs last longer before the next rainy season.
“No-drop” monitoring programmes, where council officials inspect for leakages and encourage residents and businesses to repair them, or repairing them themselves and charging this to their municipal accounts, may also be essential in limiting resource wastage.
Conservation should be encouraged long after the threat of drought is gone. This will add to the resilience of urban areas and keep them prepared for the next drought, regardless of its severity.
It has been reported that in urban areas only 15% of rain water enters the ground. This is a stark difference from 50% groundwater infiltration in rural areas. Pavements, roads and other infrastructure in urban areas cause excessive water runoff. While some of this ends up in dams, much flows into rivers that empty directly into the ocean. The department of local government should therefore improve its diligence and ensure that going forward no new infrastructure is built on wetlands, which are responsible for replenishing ground water.
Higher tariffs may have to be introduced for heavy water users in drought years, or even a few months before forecast droughts, to disincentivise excess water consumption. Water reclamation can also be encouraged, with councils buying back grey water for filtration and redistribution for nonhuman consumption, or strongly encouraging reuse by residents themselves.
The department of agriculture should also strive for wider use of drip irrigation technologies in local agriculture. Globally, agriculture is reported to be responsible for up to 70% of total fresh water consumption. Water savings by farming operations will therefore improve the country’s resilience and adaptability in times of crisis.
The department should also ensure that as soon as the cropping season nears an end it establishes reliable estimates of the country’s forthcoming harvest. This is useful to determine whether imports of grain will be necessary and how much will be needed. If imports are required they should be expeditiously arranged. Promptly acquiring imports can help pre-empt steeper grain prices in the latter half of the year, since it is likely that all or most of the Southern African Development Community region will experience the same El Niño-induced weather conditions.
Villagers in rural areas will also need education on conservation and the various measures that can be used to help rainwater infiltration and avoid excessive runoff and erosion. These may include reforestation, afforestation and agroforestry, which involves the establishment of crops, trees, vegetation and livestock on farms regardless of their location and their primary agricultural focus.
Agroforestry has the further advantage of creating microclimates that result in more rainfall than surrounding areas due to their balanced ecological conditions.
To promote the viability of arid regions the Treasury could establish more favourable special economic zone incentives for those areas. This will assist in reducing their dependency on rainfall for economic activity. In areas where economic and infrastructural development are unthinkable due to aridity, it may be crucial for the department of social development to relocate the residents to assure their wellbeing.
The departments of education and social development should monitor school drop-out rates more diligently and preset campaigns and measures to deter teen pregnancies and child marriages, which are often caused by drought-induced poverty.
Ultimately, there is a need for a multisectoral, co-ordinated and updated response to drought. This will streamline government measures and avert the evolution of coming droughts into fully fledged crises. Promoting water conservation, before or during droughts, will also keep the country physically, mentally and administratively prepared for the next drought.
As drought is a weather phenomenon, strategies should be flexible enough to switch budget commitments to other government departments if a forecast drought does not unfold in line with initial estimates. Once the country has an expertly drafted drought plan it can expand on it to integrate its SADC peers.
