Irrigation and rain-fed agriculture water systems are essential components of South Africa’s agricultural practices. Due to varying climatic conditions and water availability across different regions, watering systems play crucial roles in the country’s agricultural sector. Each approach has its significance and challenges, and farmers in South Africa often use a combination of both methods to optimise crop production. Incorporating water saving devices will ensure the previous resource is conserved.
Irrigation water management
Irrigation is the man-made supply of water to land for the development of crops or other vegetation using furrows, channels, or pipelines where rainfall cannot provide the essential water for crop growth and output. Across the country, the climate varies, and in areas where there is less rainfall, there is a need for man-made irrigation systems, such as centre pivot irrigation. A popular water management system in agriculture, a pivot system – sprinklers that move on wheeled towers in a circular pattern – is able to distribute water across large flat areas.
Some of the water management advantages of this system include a controlled water supply, increased crop yield, year-round crop cultivation and harvesting, and crop diversification, meaning farmers are able to rotate their crops more often.
No system can be without cons, however. Irrigation systems have high set up and maintenance costs, and the operation of the system may require additional investments. A good irrigation system also requires a stable water source, sufficient for the type of crop being farmed. It also goes without saying that some irrigation methods can be energy-intensive, leading to higher operational costs and carbon emissions. Properly managing irrigation systems demands knowledge and skills, and small-scale farmers may find it challenging to optimise their water usage effectively.
Rain-fed irrigation water management
Sustainable water management practices, efficient irrigation systems, and water conservation efforts are essential to ensure the long-term viability of agriculture, considering the increasing pressure on water resources due to population growth and climate change. The natural watering of soil through direct rainfall, rain-fed irrigation also requires a water management system. Although this kind of agricultural water system requires little to no initial costs, is environmentally friendly, is suitable for certain crops, and operates on reduced energy consumption, the supply of water to the crops needs to be managed.
Over irrigation can result in waterlogging, decreasing the productive capacity of the soil. In addition, micro nutrients are lost through excess water run-off.
Water Utility Solutions
At Water Utility Solutions, we believe in efficiency and accuracy when managing water, no matter the sector. In agriculture, an integrated approach which combines both irrigation and rain-fed agriculture can be the most effective and sustainable strategy. By using irrigation in water-scarce areas and rain-fed agriculture in regions with sufficient rainfall, the agricultural sector can optimise crop production and resilience to climate variability.
For this reason, our Kamstrup smart water meters, integrated with ultrasonic technology, provides accurate water readings to ensure sustainable water management. They use intelligent alarms to detect water leaks, bursts and reverse flow.
Our turnkey solutions make it easy to monitor usage, detect leaks, and reduce waste. With real-time data and automated reporting, you can save time and money. In agriculture, accurate water readings can mean the difference between a successful or unsuccessful harvest.
