Hydroponic vertical farming brings fresh produce to non-arable regions



Hydroponic vertical farming brings fresh produce to non-arable regions

The Smart Acres farm consists of eight shipping containers equipped with modules that use internet of things technology to monitor for humidity, temperature, and the nutrients inside the plants. It’s all in the name of creating an environment that’s optimized for plant growth and high nutritional value. “When we come in, we have air showers built into our facilities. We make sure that our controlled environment is as sterile as possible to protect the plants from external factors,” says Phongsavanh.

Having fine-tuned the process for leafy greens, the team is preparing to expand its crop. First up: strawberries, a local favorite. “There’s no leading vertical farm in the UAE right now that is commercializing strawberries. So, in fact, we would love to be the first one to test it and get it right,” says Phongsavanh.

Laurel Ruma: From MIT Technology Review, I’m Laurel Ruma. And this is Business Lab, the show that helps business leaders make sense of new technologies coming out of the lab and into the marketplace.

Our topic today is hydroponic vertical farming as a possible solution to food availability challenges in areas like the United Arab Emirates, where the region has little arable land, scarce water for irrigation and far more people than it can feed through its own production. Traditional farming simply isn’t viable. Fortunately, science and technology are finding a way.

Two words for you, food security.

My guest today is Aphisith Phongsavanh, lead project manager of Smart Acres. Smart Acres is an indoor vertical hydroponic farm that grows pesticide-free leafy greens using 1/10th of the land and 90% less water than traditional farming.

This podcast is produced in association with the UAE Pavilion Expo 2020 Dubai.

Welcome Aphisith.

Aphisith: Thanks for having me.

Laurel: In the United Arab Emirates, Smart Acres is one of the leaders in vertical farming. Where is the company right now in its development stage?

Aphisith: After being operational throughout our POC stage for the last three years, we’ve now moved on and integrated a newer version of our growth module, version 2.0. We’ve basically taken into consideration the challenges that we’ve faced with the first model, and we’ve gone ahead and made sure that our newer module is ready to go with better circulation systems, better regulation of humidity and AC, enabled modulation of light intensities during different stages of growth. And in total, all of these changes just resulted in better energy efficiency.

Laurel: So Aphisith, if I were to walk in on your vertical farm today, what would I see, actually? It’s a shipping container?

Aphisith: Sure. So right now, we have eight shipping containers placed in such a way that they’re interconnected for efficiency. You would walk in, they’re all horizontal, by the way, none of them are standing up. You would walk into the entrance container where you would be required to remove your shoes and external clothing such as jackets and sweaters. You’d put on PPE, wash your hands, put on sanitized boots as well, and then walk through a closed air shower. And then you would make your way into the work module and to the right of the work module, we have four growth containers. And then right beside the fourth one, we have a germination module that’s used for germinating our seeds for transplantation into the growth modules. The last module is a packing and a storage facility.

Laurel: Countries like the United Arab Emirates where traditional farming is next to impossible are food dependent. What does that mean, and how does that affect the quality and availability of fresh produce?

Aphisith: Living in a region with a lot of non-arable land and in arid conditions, we’re not able to produce a lot of the crops needed for consumption for the nation. The UAE actually imports 90% of the food for consumption. That’s one factor that we take into consideration when it comes to being food insecure.

Being food insecure, we import a lot of crops from around the world, and that impacts the quality and availability because let’s say, for instance, during the pandemic or even global crises, if you were to have logistical challenges with transport, you’re going to have disruptions in the supply chain. Second of all, the quality. When you have crops being flow in, you’re going to have a great reduction of nutrient value when it comes to healthy foods.

Laurel: Although there are several reasons for poor food production in the UAE, the scarcity of water contributes heavily. Most of the water in the country is recycled and reused, but this process itself can only happen so many times. How does vertical farming address this challenge?

Aphisith: In essence, traditional farming uses a lot of the world’s water for agricultural purposes. A lot of the water is wasted via poor irrigation, evaporation, and just water mismanagement. What vertical farming looks to address is proper efficient use of the water — up to 95% less water than traditional farming methods.

Laurel: Well, looking at the photographs that Smart Acres had posted on social media, I was struck by how green and vibrant the produce is. The heads of lettuce and kale are just beautiful. But one thing that is surprising to see is that your farmers are wearing lab coats, so this looks a lot more like science than traditional farming. Is that a correct assessment?

Aphisith: That’s a really funny observation. Yes, a lot of people do actually make the same observation, and there is a lot of science in what we do, but the main purpose for our PPE, our personal protective equipment, is actually for the crops themselves. When we come in, we have air showers built into our facilities. We make sure that our controlled environment is as sterile as possible to protect the plants from external factors. For an example, even exhalation with our team members. There’s a lot of CO2 that is exhaled and in order for us to keep our environment as consistent and controlled as possible, even the CO2 in the air must be controlled and kept at a consistent rate. These are the reasons why we do wear personal protective equipment, not just for our sake, but mainly for the plants’ sake. Because we do not use any pesticides, we want to make sure that our crops are as healthy as possible for consumption.

Laurel: And keeping the growing in such a contained environment. It sounds like one, it’s good for the plants because they are in a very specific environment that allows for rapid growth and the most nutrient growth. But are there other reasons? What would happen if a pest was somehow accidentally introduced to one of these vertical farms?

Aphisith: When you say a pest, what kind of pest are you referring to? Are you referring to the critter kind?

Laurel: Yes.

Aphisith: That’s an interesting question. We haven’t faced that challenge as of yet, but in terms of protocols, we’d definitely have to sweep the entire system front and back, inside and out with a full-scale disinfection program. But, as I mentioned before, we make sure that all of our team members wear PPE. They wash their hands probably more than 10, 20 times a shift, upon requirements, and there’s an air shower as well at the entrance. So, we try to minimize any external pests that do come in but, as mentioned, if we do happen to find one in the near future, there would be a 100% lockdown and a disinfection.

Laurel: Smart Acres uses this type of state-of-the-art technology to maintain the optimal conditions for growth and nourishment as we said, but you also have in-house growing modules and an internet of things based technology system to help these modules. Could you tell us more about how these technologies ensure high quality crops?

Aphisith: Sure. To begin with our modules, they’re fitted freight containers with individual complete HVAC systems within each module. And we house around 1,920 pots per unit. Part two, our system is a proprietary cloud-based system, and we implement live data monitoring systems via mobile apps. We can control the specific parameters and set targets, and overall, the system is capable of self-adjusting. And what I mean by self-adjusting, there are five main conditions that we control: light, humidity, circulation, nutrients, and temperature. Now, all of those play a big factor in the cultivation of our crops. We try to keep our environment as consistent as possible. So as mentioned before, when it comes to lighting, for example, we found that our first module didn’t modulate the light intensities properly and there was a mismanagement of energy resources. So, we found that near the end of the cultivation, the growth stage, there was a requirement for a higher light intensity so now with our module version two, we’re able to control the intensity.

Same thing with humidity and circulation. We found that living in such a harsh environment within the UAE, humidity was a big, big problem. We managed to create a new system that balanced out the humidity levels with proper air circulation, which helps our plants grow healthier and more efficient. Because if there is high humidity, for example, there isn’t enough plant transpiration, and without proper plant transpiration, you’re not going to get the nutrients being pulled up from the root, through the stem all the way through the leaves. And then you’re going to end up with a variety of problems such as tip burns. So, with all these changes, you end up with better quality plants.

Laurel: What kind of difference are we talking about in nutritional value between a head of lettuce that’s farmed traditionally versus one at Smart Acres? And why is this so important?

Aphisith: We haven’t actually completed our nutritional analysis yet. We are planning to because we just switched to version 2.0 of our module. But when looking at a traditionally farmed head of lettuce versus a vertically farmed head of lettuce at Smart Acres, you can just instinctively tell right off the bat, in terms of nutritional value, because when crops are transported and flown in from halfway across the world, they lose a lot of their nutrient content already during transportation.

When we’re growing our vertically farmed lettuce, you’re getting crops that are locally grown and there’s less time for transportation, which means you have a higher yield of nutrients in your crops. Also, with our vertically farmed lettuce at Smart Acres, we’re able to control the nutrient fertilizers. For example, when you’re farming your crops traditionally, you can spray your fertilizers, but then due to other external factors such as wind and poor irrigation, you’re going to have a lot of the fertilizer that is not properly utilized within the crop. Since we have a controlled environment and we have no soil and the roots are submerged in the water, you’re guaranteed a higher nutritional value, 100%. But, as I mentioned, we haven’t gotten around to testing and analyzing the exact numbers yet, but we will get to that.

Laurel: I’m sure there’s quite a difference. I’m imagining a freight airplane full of boxes of just perishable lettuce and poor temperature control, and everything you have to think of.

Aphisith: That’s a valid point because during transportation, it depends on the logistics company with their cold chain. And if systems go awry, then you’re going to have a lot of inventory that is not nutritionally sound, for sure.

Laurel: The idea is to expand to meet popular demand for exciting produce, not that lettuce isn’t exciting, but things like strawberries and potatoes. How does local appetites kind of influence what you grow? Or is there a scientific reason that we’re starting first with lettuces and kales?

Aphisith: Exciting reasons for the non-cool crops? Well, to begin with, vertical farming in terms of agri-tech is a novel concept and yes, it’s buzzworthy right now. But what I mean by novel, I mean the technology to make sure that you have a product that is accessible and available and affordable. It’s just not there yet because the barrier to entry is so high when it comes to high-tech vertical farming. And so, it’s easier and less of a challenge to start off with experimenting and doing R&D with leafy green vegetables, as opposed to doing high-value crops such as strawberries or staple foods such as potato seeds. So that is the first reason. We chose strawberries because yes, they are a high-value crop and a lot of people in the UAE, regardless of if they’re a local Emirati or expats, do love strawberries. So, we decided to move on with strawberries after leafy greens.

It’s not necessarily a scientific reason. There is no scientific reason for strawberries. It’s more of a business case than it is a scientific reason. In retrospect, I guess you could sort of say there is a slight scientific reason because there is no leading vertical farm in the UAE right now that is commercializing strawberries. So, in fact, we would love to be the first one to test it and get it right, so that is the science behind it I guess you could say.

When it comes to the potato seed, it’s not a scientific reason, more of a socioeconomic reason. A lot of the countries in the MENA region, Middle East, North Africa, get their potato seeds and their potatoes imported from around the globe, such as Europe and North America. We would really like to reduce and curb that dependence on that system, so if we were to grow the Middle East potato seed, it would do wonders for the local ecosystem in terms of Middle East and North Africa.

Laurel: It means such a staple food for so many different meals and available to so many different types of people who can use it around the world, certainly makes a big difference.

Aphisith: For sure. 100%. A big, big difference. I believe the potato was the third main staple crop in the world actually, behind wheat and rice. Yeah. That’s the figure.

Laurel:I was just thinking that.

Aphisith: Yeah, it’s really huge. There’s a huge market for it. But once again, it’s a socioeconomic thing for our vision with the potato seed to ensure that our neighboring countries in the MENA region can depend less on international imports and we can work within a local ecosystem.

Laurel: The future expansion plans of the company is to develop the Smart Acres Institute of Food Security and Agriculture. Talking a bit about what you said, so it’s sort of a localized food security program. This institute will be built on a plot of land owned by Smart Acres’ CEO Abdulla Al Kaabi.

Aphisith: Yes.

Laurel: What is the vision of this institute and what does it mean to invest locally? This is a reoccurring theme on a number of topics we’ve discussed today, but investing locally, growing locally, and consuming locally is certainly important for the United Arab Emirates.

Aphisith: Sure. So being as Abdulla Al Kaabi himself, our CEO, is a local Emirati, we wholeheartedly believe in investing locally. Not just because of that main fact, but because the UAE government itself, they have a mandate — the Food Security Strategy 2051. And we very much would love to participate and help as much as we can to make sure that the UAE reaches their target. When it comes to the Institute, our long-term goal is actually to be a pioneer within the region to facilitate the research and development of plant propagation. We’d really love to look into growing new crops and plants that can be grown efficiently within this harsh environment.

Let’s say for example, right now there are farms that grow melons, that grow cucumber. However, they’re using seeds from international companies that aren’t necessarily, I would say, advantageous in terms of being grown within these harsh environments. So yes, you can grow these certain crops, but how about your yield? How is your yield at the end of harvest? What about disease and pests? Are they prone to such factors? So, our long-term goal with the institute is to focus on plant propagation. And in the short term, the first crop that we wanted to experiment with is, once again, cultivating the UAE potato seed for the MENA region.

Laurel: You’re a trained chef and you have experience in award winning restaurants all over the world, so you must have a pretty unique view of this project. How do you bring your love of food and culinary expertise to this project? And what does it mean for you to be part of it where you can really help bring high quality produce to every table?

Aphisith: That’s a very layered question, and it’s a personal one, and I’ll tell you the honest truth. Because I am a chef, I feel more connected to the business philosophy in terms of food security and food sustainability, because chefs and even home cooks, you’re in tune with the ingredients. You’re touching the produce. It’s who you are. It’s who I am. Without proper ingredients, we cannot do what we are made to do. My experience as a chef gives me a different perspective when it comes to Smart Acres because I don’t just try to think of it wholly 100% from a business perspective, but I also think of it from a consumer social responsibility perspective as well, to make sure that we are doing the right thing for future generations.

To have these different perspectives and my philosophies coming together into one project, it’s very profound for me, to be honest, because even with the food wastage as a chef, we try to minimize food waste in the kitchen, and I took that philosophy with me to the company. For instance, I found ways to upcycle our wastage on the farm so that we can put it right back into the ecosystem and get value from it, as opposed to just throwing it out and having the food waste and throwing your money away.

When I say upcycling, for example, I mean taking lettuce that would otherwise be thrown out and turning it into sauces, right? Turning kale into kale chips. Turning leafy greens into crispy kimchi. There are so many ways that you can utilize the waste. And what I mean by waste, I don’t mean waste that’s spoiled, but I mean waste in terms of not meeting quality standards. Let’s say for instance, we would have a cutoff of, let’s say, one or two percent tip burn. If there is a harvest that doesn’t meet that, then it doesn’t get the passing grade, and then we can utilize that harvest for being upcycled into products for the market.

Laurel: And tip burn for folks is like, you look at a lettuce leaf and you can see browning around the edges, which makes it go bad quicker and also not maybe as beautiful when you’re trying to sell it at a market.

Aphisith: Correct. That’s what I mean by tip burn. I’ve had plenty of talks and discussions with the team here regarding imperfect plants and imperfect crops and vegetables. Some governments around the world, such as France, are implementing policies for the retail sector in terms of loving imperfect produce. I believe that is something that the global community should take into more consideration. The UAE is doing a great job because there are a few campaigns right now being pushed through the grassroots level and slowly up into the commercial sector in regards to appreciating imperfect crops and vegetables and plants and so forth. Just because something doesn’t look perfect, it doesn’t mean it doesn’t taste perfect. I always ask people, “Would you rather eat a tomato that doesn’t necessarily look nice but tastes absolutely fantastic, firm, sweet, vibrant, or eat a tomato that looks sublime, divine, but tastes like water?” And 10 out of 10 people always say, I would rather go for the imperfect tomato that tastes amazing.

Laurel: Absolutely. Aphisith, thank you so much for joining us today on the Business Lab.

Aphisith: You’re very welcome. It was great to be part of this. Thank you.

The hunter-gatherer groups at the heart of a microbiome gold rush



The hunter-gatherer groups at the heart of a microbiome gold rush

The first step to finding out is to catalogue what microbes we might have lost. To get as close to ancient microbiomes as possible, microbiologists have begun studying multiple Indigenous groups. Two have received the most attention: the Yanomami of the Amazon rainforest and the Hadza, in northern Tanzania. 

Researchers have made some startling discoveries already. A study by Sonnenburg and his colleagues, published in July, found that the gut microbiomes of the Hadza appear to include bugs that aren’t seen elsewhere—around 20% of the microbe genomes identified had not been recorded in a global catalogue of over 200,000 such genomes. The researchers found 8.4 million protein families in the guts of the 167 Hadza people they studied. Over half of them had not previously been identified in the human gut.

Plenty of other studies published in the last decade or so have helped build a picture of how the diets and lifestyles of hunter-gatherer societies influence the microbiome, and scientists have speculated on what this means for those living in more industrialized societies. But these revelations have come at a price.

A changing way of life

The Hadza people hunt wild animals and forage for fruit and honey. “We still live the ancient way of life, with arrows and old knives,” says Mangola, who works with the Olanakwe Community Fund to support education and economic projects for the Hadza. Hunters seek out food in the bush, which might include baboons, vervet monkeys, guinea fowl, kudu, porcupines, or dik-dik. Gatherers collect fruits, vegetables, and honey.

Mangola, who has met with multiple scientists over the years and participated in many research projects, has witnessed firsthand the impact of such research on his community. Much of it has been positive. But not all researchers act thoughtfully and ethically, he says, and some have exploited or harmed the community.

One enduring problem, says Mangola, is that scientists have tended to come and study the Hadza without properly explaining their research or their results. They arrive from Europe or the US, accompanied by guides, and collect feces, blood, hair, and other biological samples. Often, the people giving up these samples don’t know what they will be used for, says Mangola. Scientists get their results and publish them without returning to share them. “You tell the world [what you’ve discovered]—why can’t you come back to Tanzania to tell the Hadza?” asks Mangola. “It would bring meaning and excitement to the community,” he says.

Some scientists have talked about the Hadza as if they were living fossils, says Alyssa Crittenden, a nutritional anthropologist and biologist at the University of Nevada in Las Vegas, who has been studying and working with the Hadza for the last two decades.

The Hadza have been described as being “locked in time,” she adds, but characterizations like that don’t reflect reality. She has made many trips to Tanzania and seen for herself how life has changed. Tourists flock to the region. Roads have been built. Charities have helped the Hadza secure land rights. Mangola went abroad for his education: he has a law degree and a master’s from the Indigenous Peoples Law and Policy program at the University of Arizona.

The Download: a microbiome gold rush, and Eric Schmidt’s election misinformation plan



The Download: a microbiome gold rush, and Eric Schmidt’s election misinformation plan

Over the last couple of decades, scientists have come to realize just how important the microbes that crawl all over us are to our health. But some believe our microbiomes are in crisis—casualties of an increasingly sanitized way of life. Disturbances in the collections of microbes we host have been associated with a whole host of diseases, ranging from arthritis to Alzheimer’s.

Some might not be completely gone, though. Scientists believe many might still be hiding inside the intestines of people who don’t live in the polluted, processed environment that most of the rest of us share. They’ve been studying the feces of people like the Yanomami, an Indigenous group in the Amazon, who appear to still have some of the microbes that other people have lost. 

But there is a major catch: we don’t know whether those in hunter-gatherer societies really do have “healthier” microbiomes—and if they do, whether the benefits could be shared with others. At the same time, members of the communities being studied are concerned about the risk of what’s called biopiracy—taking natural resources from poorer countries for the benefit of wealthier ones. Read the full story.

Navigating a shifting customer-engagement landscape with generative AI



Navigating a shifting customer-engagement landscape with generative AI

A strategic imperative

Generative AI’s ability to harness customer data in a highly sophisticated manner means enterprises are accelerating plans to invest in and leverage the technology’s capabilities. In a study titled “The Future of Enterprise Data & AI,” Corinium Intelligence and WNS Triange surveyed 100 global C-suite leaders and decision-makers specializing in AI, analytics, and data. Seventy-six percent of the respondents said that their organizations are already using or planning to use generative AI.

According to McKinsey, while generative AI will affect most business functions, “four of them will likely account for 75% of the total annual value it can deliver.” Among these are marketing and sales and customer operations. Yet, despite the technology’s benefits, many leaders are unsure about the right approach to take and mindful of the risks associated with large investments.

Mapping out a generative AI pathway

One of the first challenges organizations need to overcome is senior leadership alignment. “You need the necessary strategy; you need the ability to have the necessary buy-in of people,” says Ayer. “You need to make sure that you’ve got the right use case and business case for each one of them.” In other words, a clearly defined roadmap and precise business objectives are as crucial as understanding whether a process is amenable to the use of generative AI.

The implementation of a generative AI strategy can take time. According to Ayer, business leaders should maintain a realistic perspective on the duration required for formulating a strategy, conduct necessary training across various teams and functions, and identify the areas of value addition. And for any generative AI deployment to work seamlessly, the right data ecosystems must be in place.

Ayer cites WNS Triange’s collaboration with an insurer to create a claims process by leveraging generative AI. Thanks to the new technology, the insurer can immediately assess the severity of a vehicle’s damage from an accident and make a claims recommendation based on the unstructured data provided by the client. “Because this can be immediately assessed by a surveyor and they can reach a recommendation quickly, this instantly improves the insurer’s ability to satisfy their policyholders and reduce the claims processing time,” Ayer explains.

All that, however, would not be possible without data on past claims history, repair costs, transaction data, and other necessary data sets to extract clear value from generative AI analysis. “Be very clear about data sufficiency. Don’t jump into a program where eventually you realize you don’t have the necessary data,” Ayer says.

The benefits of third-party experience

Enterprises are increasingly aware that they must embrace generative AI, but knowing where to begin is another thing. “You start off wanting to make sure you don’t repeat mistakes other people have made,” says Ayer. An external provider can help organizations avoid those mistakes and leverage best practices and frameworks for testing and defining explainability and benchmarks for return on investment (ROI).

Using pre-built solutions by external partners can expedite time to market and increase a generative AI program’s value. These solutions can harness pre-built industry-specific generative AI platforms to accelerate deployment. “Generative AI programs can be extremely complicated,” Ayer points out. “There are a lot of infrastructure requirements, touch points with customers, and internal regulations. Organizations will also have to consider using pre-built solutions to accelerate speed to value. Third-party service providers bring the expertise of having an integrated approach to all these elements.”
