JEANETTE CLARK: Climate resilience is outlined as the capability of social, financial and ecosystems to deal with a hazardous occasion or development or disturbance in the world’s current local weather. This is in line with the Intergovernmental Panel on Climate Change’s newest 2022 abstract doc for policymakers. In this podcast, our final in a collection on agriculture, we communicate to Nedbank’s Maluta Netshaulu, senior supervisor: agriculture, shopper worth proposition, about local weather resilience in our agriculture sector.
Maluta, what in your opinion are the parts of a climate-resilient agriculture sector in South Africa?
MALUTA NETSHAULU: To reply your query, we’ve bought three parts that talk to local weather resilience. The first one is sustainable manufacturing practices, second is expertise and innovation adoption, after which final however not least is sustainable options.
JEANETTE CLARK: Right. Can we dive into sustainable manufacturing practices first, what you have got seen change regionally and even internationally, if you wish to use some examples over the final couple of years? I’m particularly to listen to your ideas on regenerative farming practices.
MALUTA NETSHAULU: For the longest time I feel farmers utilized standard manufacturing practices, reaping the soil and making use of tons of fertiliser and a number of water with out a lot regard in phrases of their useful resource availability and the affect of the inputs they’re placing into the soil.
But over the years, due to shortage of sources and due to stress that has been coming from the worldwide neighborhood and shoppers, we’ve seen a radical shift away from these practices into extra sustainable practices that promote sustainable manufacturing practices in phrases of ecologically pleasant practices, utilizing much less dangerous materials into extra natural matter that’s way more pleasant in phrases of the soil, in phrases of the water, in addition to the surroundings.
So farming has now actually modified, however it’s additionally going into that course. I’m making an attempt to say that not everybody has moved that means, however we’ve seen a number of farmers shifting that means as a result of it’s now not about profitability; it’s additionally about with the ability to be sustainable in attaining these outcomes.
Then, on the subject of a few of the greater developments, it’s on manufacturing practices that actually promote discount of carbon sequestration like, for instance, on the subject of regenerative agriculture or conservation agriculture. That’s the place you’d discover that the sort of farming promotes farming such that, at any given level in time, in a yr or a season, the land is rarely actually left naked.
If you drive on the N1 in the direction of Bloemfontein, and even in the direction of Limpopo for that matter, you might discover throughout the winter months, and even in another months, after the farmers have harvested the lands and simply ready them, ready for the subsequent season.
In a way, whereas they’re doing these preparations and clearing the land from the earlier season, that releases a number of carbon into the ambiance and a number of vitamins are misplaced in consequence, as a result of the land is simply naked.
But on the subject of regenerative agriculture, you discover that they do intercropping, whether or not now we have maize and in between, the rows, cowl crops, or instantly after harvesting in addition they guarantee that they don’t actually clear the land, however then they permit [the planting of] different crops over no matter stays on the land, which actually promotes, in phrases of the ecological steadiness, ensuring that to no matter is there, issues which might be residing in the land, there isn’t a disruption, and the water content material of the soil stays good.
And then we see that, as they begin the new manufacturing season, it additionally saves rather a lot on soil, on chemical substances and all these issues which, at the finish of the day, assist their backside line. That’s extra the essence, in phrases of what a dialog or regenerative agriculture is all about.
JEANETTE CLARK: Your colleague, John Hudson, drove the level residence fairly strongly about farmers right here in South Africa having to do extra with much less. How does expertise and innovation adoption help in this regard, additionally serving to to bolster local weather resilience?
MALUTA NETSHAULU: I feel John did put it effectively. His assertion was round ‘if you think agriculture and technology don’t go collectively, you’re fairly fallacious’. That’s what we’ve seen in agriculture. For instance, gone are the days when [no technology is used], besides in a really smallholder-type of setup.
But on the subject of business and even the mega-farmers, from the use of tractors, extremely refined items of equipment, the use of irrigation techniques, the use of issues like IoT [the Internet of Things] units, remote-sensing, aerial and drone imagery and all these issues, and precision farming – these are very refined expertise techniques which might be getting used on farms to assist the farmer know what’s taking place on [their] farm. And be capable of make higher choices in phrases of the place to use what, primarily based on what knowledge has been acquired. If it’s aerial imagery, you’ll be able to spot the place there’s stress in your farm; the place you want [to pay] consideration.
Some of the suggestions that you simply’re getting includes issues that you simply can not see with the bare eye. So with the ability to act primarily based on that knowledge, I feel, is vital, as a result of by so doing you’re then capable of mitigate lack of revenue, otherwise you [are] having to behave when it’s a bit too late; it would imply that it’s essential to apply extra in phrases of corrective measures.
That’s what expertise has finished for the sector. It has now grow to be such that it’s regular for farmers to be utilizing this expertise simply from their tractors – [whether it’s] a John Deere or Massey Ferguson, or Case, for instance, they’ll simply examine from their display whereas they’re engaged on the land, both planting or harvesting – to see what’s going on, what’s the suggestions they’re getting from the sensors of that equipment, and be capable of act up upon it. And even at that actual second or afterwards to have the ability to see and say, oh, that is what I managed to reap on this subject, particular to that subject, what are the causes for that – after which be capable of plan accordingly.
So that’s what expertise and innovation adoption have come to [mean] on the subject of agriculture.
JEANETTE CLARK: Well, I see that even agriculture can’t escape massive knowledge, and I assume it helps rather a lot as effectively to grasp the climate patterns and to plan for that. But it doesn’t at all times need to be excessive tech. There are different sustainable farming interventions that may help in serving to with sure climate occasions, or climate modifications. Can you give me some examples of this?
MALUTA NETSHAULU: Yes, most undoubtedly. When you take a look at local weather change, we’re seeing a number of climate that’s fairly erratic, not simple to foretell. I’m not speaking [about things] like rain. Let’s speak about issues like pure hazards, like extra wind or hail, or issues like frost in winter.
So these improvements which might be on the market, for instance shade-netting or hail nets as they’re additionally identified that farmers, particularly those that function in areas the place they’re very inclined to these kinds of pure hazards, they usually’re farming with very excessive kinds of cultivars of produce. Like in the citrus area, we’re speaking mushy citrus, or in the wine area or table-grape area, and even [about] macadamias for that matter, they can set up these options that are additionally not low cost, to be trustworthy, however they do enable them the alternative to type of fight or shield their high-value orchards from these pure hazards.
They can even enhance the efficiency of these orchards by 20%, cut back water utilization, cut back fertiliser or nitrogen functions. So at the finish of the day, they assist farmers to make use of these improvements nearly like insurance coverage, particularly on the subject of tree crops, insurance coverage may be very costly. Most individuals can’t afford it and most of the people don’t take it. So they find yourself utilizing such improvements like shade netting to function insurance coverage and in addition assist them shield [valuable] manufacturing and orchards.
Something that it additionally helps is like cross-pollination. If you’ve bought seeded desk grapes on the different aspect, adjoining to a seedless [variety], and also you’ve a contract with, say, Woolworths or Checkers, for the seedless [variety], and it’s essential to ship at the finish of that season, if that different seeded [variety] type of cross-pollinates your seedless one, then it’s going to consequence in you shedding the contract, which can ripple into different points for you in phrases of market entry and so forth. So, by having that web, you type of mitigate that danger of cross-pollination and the birds consuming your crops and so forth.
So it’s a really, excellent instance of what sustainable options are on the market that farmers are adopting, and they’re seeing worth in phrases of their operations.
JEANETTE CLARK: You talked about local weather change, and a technique of combating local weather change is to take a look at different and renewable power options. But why do you assume farmers are turning to different and renewable power options? Is it at all times a climate-change matter, or is it generally simply survival as a result of they’ll’t essentially rely on their electrical energy all the time?
MALUTA NETSHAULU: I feel it’s extra round the latter assertion that you simply simply talked about. It’s all about an power supply that’s dependable. In South Africa, with the entire instability and unreliability of the grid for numerous causes – it could possibly be load shedding or it could possibly be cable theft, it could possibly be [a] cable fault, or it may simply be vandalism of the system – if farmers are going to have a number of downtime and farmers who’re utilizing electrical energy to energy their irrigation techniques, to energy their milking parlour, or to energy their processing plant, that does have a number of detrimental affect in phrases of their profitability. It may even consequence in their having to shed jobs.
So it’s come to some extent the place we’ve seen a number of farmers adopting renewable power options like photo voltaic PV [photovoltaics], for instance, the place they are going to set up that to guarantee that they mitigate the danger of downtime due to these issues that I discussed.
So it’s true. We’ve seen that rather a lot. Even from Nedbank, we’ve seen a number of requests for funding of renewable power installations for our farmers, simply to guarantee that they’re resilient in opposition to such dangers as load shedding, for instance.
JEANETTE CLARK: So local weather resilience is a subject that’s intently tied to local weather change. But even with out bringing that into the image, southern Africa has at all times had excessive rainfall variability. Even in what we’d take into account a standard yr farmers would profit from boosting their local weather resilience for the sake of meals manufacturing and the South African economic system.
