As the drought afflicting the Western Cape and parts of the Eastern Cape shows no sign of abating, deciduous fruit farmers are considering contingency plans for the coming season, according to deciduous fruit farmers organisation Hortgro.
“Growing fruit trees is a long-term investment with orchards bearing fruit over multiple seasons. It has been one of the driest winters in recent history, with unprecedented low dam levels and pressure on the water infrastructure servicing Cape Town and other municipal areas in the region,” Hortgro spokesman Jacques du Preez said.
Fruit farmers, who were reliant on irrigation water to produce their crops, apprehensively awaited rain to fill up their dams. The water situation differed between regions – with some growers reporting enough water to at least see through most of the summer, while others reported only fractions of the required amounts of water available for the coming season.
Hortgro recently presented an irrigation seminar to equip producers with the tools and strategies to mitigate the impact of the drought as well as possible. Since the future scenario of a drying climate required that all new plantings were highly efficient, the seminar revisited the basic principles of irrigation design and planning.
Stages during the season when trees might be more or less sensitive to drought stress or when conditions allowed water saving were identified while various practices and technologies to save water, such as mulching, restricting irrigation to the root zone, and netting were discussed, he said.
An encompassing drought strategy was presented by a Ceres fruit grower. The strategy involved ranking and allocating water to orchards according to profitability. This would entail optimal irrigation of highly profitable orchards, restriction of water allocation to less profitable orchards, and the removal of unproductive orchards. The strategy would be reassessed during monthly water budget meetings.
In line with the drought strategy, many growers had brought forward their plans to remove older, less productive orchards over the next couple of years to stretch the water they had as far as possible. Others had decided to remove all the fruit from trees in anticipation of the fact that they would not be able to raise a crop and keep their trees alive.
In the end the allocation of water would be an economic decision with the most productive long-term crops getting the advantage over lower yielding orchards or short-term crops, such as onions and potatoes.
“Fruit producers, however, are resilient and have been using technology much more actively and effectively in managing their water, irrigation systems, and orchards. Water has always been a limited and limiting resource – the past seasons and this coming season will continue to hone growers’ skills to make every drop count,” Du Preez said.
A lot could still happen and the situation could quickly change for the better if adequate rain fell, but as it stood at the moment at the tail end of the primary rainfall season in the Western Cape, a decrease in production, exports and foreign earnings, employment, and its associated social impact was something that in all likelihood would occur.
“The magnitude will be determined over the next month and a half. The flipside of a drought and silver lining for fruit farmers is that the eating quality of fruit under water scarce conditions is usually very good with high sugar levels and good taste,” Du Preez said.
