Climate resilience within the agriculture sector

JEANETTE CLARK: Climate resilience is outlined because the capability of social, financial and ecosystems to deal with a hazardous occasion or development or disturbance on the planet’s present 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 sequence on agriculture, we converse 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 elements of a climate-resilient agriculture sector in South Africa?

MALUTA NETSHAULU: To reply your query, we’ve received three elements that talk to local weather resilience. The first one is sustainable manufacturing practices, second is know-how 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 will have seen change regionally and even internationally, if you wish to use some examples during the last couple of years? I’m particularly to listen to your ideas on regenerative farming practices.

MALUTA NETSHAULU: For the longest time I believe farmers utilized standard manufacturing practices, reaping the soil and making use of tons of fertiliser and a variety of water with out a lot regard by way of their useful resource availability and the impression of the inputs they’re placing into the soil.

But over time, due to shortage of sources and due to strain that has been coming from the worldwide group and shoppers, we’ve seen a radical shift away from these practices into extra sustainable practices that promote sustainable manufacturing practices by way of ecologically pleasant practices, utilizing much less dangerous materials into extra natural matter that’s way more pleasant by way of the soil, by way of the water, in addition to the setting.

So farming has now actually modified, nevertheless it’s additionally going into that course. I’m attempting to say that not everybody has moved that method, however we’ve seen a variety of farmers shifting that method as a result of it’s not about profitability; it’s additionally about having the ability to be sustainable in attaining these outcomes.

Then, with regards to a number of the greater traits, it’s on manufacturing practices that actually promote discount of carbon sequestration like, for instance, with regards to regenerative agriculture or conservation agriculture. That’s the place you’ll discover that one of these farming promotes farming such that, at any given time limit, in a yr or a season, the land is rarely actually left naked.

If you drive on the N1 in direction of Bloemfontein, and even in direction of Limpopo for that matter, it’s possible you’ll discover in the course of the winter months, and even in another months, after the farmers have harvested the lands and simply ready them, ready for the following season.

In a way, whereas they’re doing these preparations and clearing the land from the earlier season, that releases a variety of carbon into the environment and a variety of vitamins are misplaced because of this, as a result of the land is simply naked.

But with regards to 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 additionally 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, by way of the ecological stability, ensuring that to no matter is there, issues which might be dwelling within the land, there isn’t any disruption, and the water content material of the soil stays good.

And then we see that, as they begin the brand new manufacturing season, it additionally saves quite a bit on soil, on chemical substances and all these issues which, on the finish of the day, assist their backside line. That’s extra the essence, by way of what a dialog or regenerative agriculture is all about.

JEANETTE CLARK: Your colleague, John Hudson, drove the purpose dwelling fairly strongly about farmers right here in South Africa having to do extra with much less. How does know-how and innovation adoption help on this regard, additionally serving to to bolster local weather resilience?

MALUTA NETSHAULU: I believe John did put it properly. His assertion was round ‘if you think agriculture and technology don’t go collectively, you’re fairly mistaken’. That’s what we’ve seen in agriculture. For instance, gone are the times when [no technology is used], besides in a really smallholder-type of setup.

But with regards to industrial and even the mega-farmers, from using tractors, extremely refined items of equipment, using irrigation methods, using issues like IoT [the Internet of Things] gadgets, remote-sensing, aerial and drone imagery and all these issues, and precision farming – these are very refined know-how methods which might be getting used on farms to assist the farmer know what’s taking place on [their] farm. And have the ability to make higher selections by way of the place to use what, primarily based on what knowledge has been obtained. 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 having the ability to act primarily based on that knowledge, I believe, is vital, as a result of by so doing you’re then in a position to mitigate lack of revenue, otherwise you [are] having to behave when it’s a bit too late; it’d imply that it’s essential apply extra by way of corrective measures.

That’s what know-how has carried out for the sector. It has now turn out to be such that it’s regular for farmers to be utilizing this know-how simply from their tractors – [whether it’s] a John Deere or Massey Ferguson, or Case, for instance, they will simply test 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 have the ability to 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 explanations for that – after which have the ability to plan accordingly.

So that’s what know-how and innovation adoption have come to [mean] with regards to agriculture.

JEANETTE CLARK: Well, I see that even agriculture can’t escape large knowledge, and I suppose it helps quite a bit as properly to know the climate patterns and to plan for that. But it doesn’t all the time 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 variety of climate that’s fairly erratic, not simple to foretell. I’m not speaking [about things] like rain. Let’s discuss 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 recognized that farmers, particularly those that function in areas the place they’re very vulnerable to these forms of pure hazards, they usually’re farming with very excessive forms of cultivars of produce. Like within the citrus area, we’re speaking mushy citrus, or within 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 sincere, however they do enable them the chance to type of fight or defend their high-value orchards from these pure hazards.

They also can enhance the efficiency of these orchards by 20%, scale back water utilization, scale back fertiliser or nitrogen functions. So on the finish of the day, they assist farmers to make use of these improvements virtually like insurance coverage, particularly with regards to 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 defend [valuable] manufacturing and orchards.

Something that it additionally helps is like cross-pollination. If you’ve received seeded desk grapes on the opposite 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 ship on the finish of that season, if that different seeded [variety] type of cross-pollinates your seedless one, then it’s going to end in you dropping the contract, which can ripple into different points for you by way of market entry and so forth. So, by having that web, you type of mitigate that threat of cross-pollination and the birds consuming your crops and so forth.

So it’s a really, superb instance of what sustainable options are on the market that farmers are adopting, and they’re seeing worth by way of their operations.

JEANETTE CLARK: You talked about local weather change, and a method of combating local weather change is to have a look at different and renewable vitality options. But why do you assume farmers are turning to different and renewable vitality options? Is it all the time a climate-change matter, or is it typically simply survival as a result of they will’t essentially depend on their electrical energy on a regular basis?

MALUTA NETSHAULU: I believe it’s extra across the latter assertion that you simply simply talked about. It’s all about an vitality 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 variety of downtime and farmers who’re utilizing electrical energy to energy their irrigation methods, to energy their milking parlour, or to energy their processing plant, that does have a variety of detrimental impression by way of their profitability. It may even end result of their having to shed jobs.

So it’s come to a degree the place we’ve seen a variety of farmers adopting renewable vitality options like photo voltaic PV [photovoltaics], for instance, the place they’ll 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 variety of requests for funding of renewable vitality 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 carefully tied to local weather change. But even with out bringing that into the image, southern Africa has all the time had excessive rainfall variability. Even in what we might think about a standard yr farmers would profit from boosting their local weather resilience for the sake of meals manufacturing and the South African financial system.

We have been talking as we speak to Maluta Netshaulu, senior supervisor: agriculture, shopper worth proposition, at Nedbank.
