Global stakeholders should use AI to mitigate impact of heat islands in cities

If human societies do nothing, in just a few decades, the planet could warm to levels it hasn’t reached in at least 34 million years, leading to more melting glaciers and floods than ever before — as well as the dire effect of urban heat waves.

In 2021, in the U.S. alone, there were already 18 extreme climate-related disasters with losses exceeding $1 billion each, according to the National Oceanic and Atmospheric Administration.

When looking at the world’s natural calamities on a consequence and frequency scale, floods and earthquakes have a more devastating effect on people and property, but they occur less frequently than heat waves, which generally take the form of urban heat islands (UHIs). These are also known as heat pockets, which are found across cities’ downtown areas, where temperatures are higher than the peripheries.

With urbanized areas warming up fast, many more populations globally are bound to face the deadly consequences of the heat-island effect, highlighting urban public health disparities. Between 2000 and 2016, according to the World Health Organization, the number of people exposed to heat waves jumped by 125 million, claiming more than 166,000 lives between 1998 and 2017.

City officials in the U.S. now worry that intense heat could lower comfort levels and conditions for residents, especially the most vulnerable populations — but cities are not equipped with the right data to mitigate effects.

Working at a design-led data science company, I know that building sustainable solutions for organizations or solving complex business, societal and socioeconomic problems can be solved using advanced analytics, artificial intelligence (AI) techniques and interactive data visualizations.

Despite this, these emerging technologies can only be rolled out through collaborations among public health professionals, enterprises, local governments, communities, nonprofits and technology partners. This cross-sector intervention is the only way to democratize technology and rectify the urban heat-island devastation. So, how are these players working together to reduce urban heat islands?

Understanding which countries make significant contributions

A handful of companies, governments and NGOs across the world are working to solve the problem with heat waves.

However, since Canada warmed by an average of 1.6°C between 1948 and 2012, roughly double the global average rate of warming, it’s way ahead of the game when using AI to predict heat waves. By nature, Canadian cities are technology-driven and tech-savvy, so cities across the world can look to the country for in-depth analysis and innovative ideas. For example, MyHeat tracks the solar potential of buildings, taking the heat wave and using it to create sustainable energy.

European cities, including Helsinki and Amsterdam, are also trying to tackle this challenge. AI4Cities is an EU-funded project bringing together leading European cities looking for AI solutions to accelerate carbon neutrality. The total funding amount of 4.6 million euros will be divided among selected suppliers.

Despite these projects leveraging AI to solve climate change issues, they are still concentrating on other niches, such as reducing carbon footprint. They focus on the mitigation of the cause of climate change instead of the effect.

Therefore, the impact of heat waves remains a largely unsolved problem. This is also because other natural disasters, such as floods that cause huge immediate effects, get more attention. Heat waves are silent killers with their undercurrents of thermal discomfort, more energy usage and power outages. And perhaps the biggest challenge is that the kind of technology to face heat waves is not openly available to municipalities or nonprofits.

Leveraging AI-powered solutions

Through working with Evergreen, a nonprofit building resilient cities and mitigating climate risks, we were introduced to a network of cities in Canada. And after research and surveys, we realized that there’s a lot of digital infrastructure and data-driven decision-making for floods and earthquakes, but none or very few solutions for heat waves.

Heat waves remain largely an unsolved problem, and there’s a huge opportunity for AI, as a scalable tool, to inform cities to make evidence-based decisions.

Evergreen uses geospatial analytics, AI and big data, alongside a data visualization tool created through the Microsoft AI for Earth grant, to integrate and analyze different datasets that examine urban heat islands across cities. This helps municipalities pinpoint problem areas with low vegetation or impermeable surfaces and mitigate the effects of heat islands by installing cool roofs, water fountains and green roofs.

The AI-powered analysis and visualization tool, built on the Microsoft Azure Stack, offers several capabilities. A map, or a topographic view, allows climate teams in municipalities to get the land surface temperature of every 30-meter block on the ground. Additionally, there’s a Scenario Modeling View that enables them to generate scenarios of the future urban sprawl of cities by modifying features like building counts and height, albedo levels and other urban sprawl parameters.

This multipurpose tool is already impacting climate resilience in municipalities across Canada by tracking greenhouse gases. It could also positively impact policy shifts around greenhouse and carbon dioxide emissions worldwide in years to come.

Sustainable Environment and Ecological Development Society (SEEDS), with Microsoft India, also announced its second phase of an AI model for predicting heat wave risks in India and offering cost-effective interventions. If a heat wave occurs, governments can work out which areas of the city need help and attention. SEEDS uses ground-truth data, and the AI model generates results that are validated on the ground with thermal sensors, among other devices.

City officials should welcome AI as an economical way to face heat wave problems as it is scalable and quickly applicable worldwide — it is agnostic to locality or ground presence. AI can also be packaged into a tool to extract data sources, which makes the knowledge easily shareable across departments and key stakeholders, and digestible for decision-makers.

With Evergreen, the idea is to create a public-facing app, which informs communities about the kind of impact AI has, offering real-life solutions and bringing them alive in a storytelling mode. For example, the app could show how temperatures decreased due to a green roof installation. It would allow users to see data insights as easily consumable stories and help them understand the different complexities that shape the issue they are tackling.

Democratizing and scaling AI at the speed of trust

Working with multiple data sources for AI or machine learning (ML) projects calls for cross-sector solutions. The involvement of nonprofits and community builders is crucial — they act as conduits between technology players, enterprises, other nonprofits, governments, communities, city planners, real estate developers and mayors’ offices.

Technology partners cannot just arrive in a city with an AI solution and expect officials to subscribe to it. You have to make a business case and enable all players to be part of the conversation; it is a multisectoral endeavor.

Equally, the stakeholders who would use this innovative technology won’t just automatically adopt this tool if they are told: “You have a heat pocket. I can install a green roof to help you.”

Let’s take a geospatial example, developed in partnership with Microsoft AI for Earth’s initiative. The entire population of a city was mapped — with release points within blocks of 100 square meters in a 40-meter grid — to release genetically modified mosquitoes to kill dangerous, disease-carrying mosquitoes.

This scalable solution with AI can bring resolutions to communities suffering from dengue and yellow fever. But if someone came to your house and said that you would be inundated with genetically modified mosquitoes, you would most likely say no, mainly due to the idea of being overrun with mosquitoes, but also because of the global resistance against AI as it evolves. There are worries around it magnifying the ability to use personal information that intrudes on privacy interests.

This is why the projects that succeed are often executed by educating communities. Community partnerships are key to spreading positive messaging about bringing down temperatures, using less energy and adopting climate-friendly AI technology.

In Canada, for example, every city has its own climate team, weather model and sensors in crucial places across urban zones. It is challenging for large data or technology companies to get hold of this weather data; cities must be willing to share. It is the same with high-resolution, high-quality satellite imagery working out cloud coverage; you need data providers to inform you about population data and socioeconomic considerations.

Therefore, projects have to be done at the speed of trust. Cities will be more inclined to share data points with technology companies that can offer real, scalable solutions when they have established credibility. Without this, these companies will have to rely on publicly available and open source data from NASA and Copernicus.

So, what does this all mean for enterprise players and their CEOs? AI solutions for cities are targeted toward climate teams and communities in municipalities. But what about oil and gas companies? They are under huge pressure to report their carbon footprints as they contribute to many of the emissions in cities.

An AI solution for them would involve a tracking command center to follow on a real-time basis how much carbon emissions their refineries or freight is leaving in their wake. CEOs have a mandate to decrease their per-product, per-employee carbon footprint. Adopting an AI solution would hold them accountable for environmental effects while showing that they are also aware of being part of the problem with heat waves.

COVID-19 brought attention to heat waves as more people were living at home than working in offices. This means populations experienced higher temperatures and discomfort in more pronounced ways, removed from the general facilities and comforts of offices.

Leaders across the social change community can reverse these dire effects of climate change and heat waves through facilitating collaborations among enterprises, NGOs, governments, technology partners and community leaders. This will mean the potential solutions that have arisen from AI and ML can be rolled out sooner rather than simply too late.

Clean energy firm Husk signs UN energy compact as it begins solar mini-grid expansion in Nigeria, rest of Africa

Published

on

Husk Power Systems, a clean energy company that has been at the forefront of fueling rural electrification since 2008, is planning to launch 500 solar mini-grids in Nigeria over the next five years.

The renewable energy firm revealed the plans today when it announced the signing of a voluntary commitment with the United Nations to grow its energy market in sub-Saharan Africa and South Asia. The commitment is contained under the 24/7 Carbon-free Energy Compact, by leading energy buyers, suppliers, equipment manufacturers and governments. The compact represents a global effort to accelerate the uptake of carbon-free electricity as a way of averting the perilous effects of climate change.

The startup currently has operations in Nigeria, Tanzania and India (Uttar Pradesh and Bihar), where it has the ambitious goal of installing at least 5,000 mini-grids by 2030 and in the process make 1 million connections – half of which will be micro, small and medium-sized enterprises. Husk launched its first six mini-grids in Nigeria November last year, and it’s looking to have 100 mini-grids operational in the country within two years.

“Husk is committed to powering households, but our focus is first and foremost on micro, small and medium enterprises (MSMEs), and public institutions like health clinics and schools. MSMEs are the engine of economies in Africa, and powering existing small businesses and encouraging the formation of new MSMEs helps create the type of economic growth and social benefit that carries over to households by creating more opportunity and more jobs,” the company’s CEO and co-founder Manoj Sinha, told TechCrunch.

The firm is now exploring growth opportunities in the western, southern and eastern regions of Africa, while prioritizing the countries that have a “supportive regulatory environment” like its current markets. In Nigeria, for example, mini-grid operators are “largely free of permit requirements for either standalone off-grid mini-grids or interconnected mini-grids.”

The Nigerian Electricity Regulatory Commission Mini-Grid Regulation (2016) stipulates the transfer of assets and financial compensation for mini-grid operators in cases where the national grid finally connects the regions where private mini-grids are operational.

Husk is one of the companies participating in the Nigeria Electrification Project, which provides performance-based grants, a sort of capital subsidy, to mini-grid developers — part of the national effort to solve the country’s chronic power supply issues.

“In terms of policy frameworks and regulation, the states where Husk works in India (Uttar Pradesh and Bihar) have supportive policies. And the Nigerian mini-grid policy is actually based on those policies, with additional improvements. As a result, Nigeria is seen to have the most conducive policy in sub-Saharan Africa at the moment, which also includes their Nigeria Electrification Project (NEP), a program administered by the Rural Electrification Agency and funded by the World Bank to provide a capital subsidy to mini-grid developers and accelerate market development,” said Sinha.

Nigeria and India are the company’s biggest markets at the moment. A supportive environment encourages investments from private players like Husk, and bridges the energy needs of households and small businesses, especially in rural areas.

Potential markets for Husk include Kenya, which at the start of this month, recognized mini-grid power systems granting them 50% tax allowance and other tax incentives enjoyed by large-scale generators.

“We welcome the Energy Compact commitments made by Husk Power and appreciate their leadership. It showcases the business opportunity presented by the global energy transition, and how private enterprises can drive accelerated action on ending energy poverty, expand renewable energy solutions for consumptive and productive load, and improve the adoption of energy efficiency solutions by end consumers,” said UN Energy programme manager, Kanika Chawla.

According to the World Bank, mini-grids have the potential to provide half a billion people with clean energy by the end of this decade (including those using overburdened grids) with the right policies in place. They also provide cleaner and cheaper alternatives of energy, which could transform the lives of millions of people living in darkness.

Sub-Saharan Africa accounts for 75% of the world’s population with no access to renewable energy solutions and electricity. Countries like South Sudan, Burundi, Chad, Malawi, Burkina Faso, Madagascar, Tanzania are among some of the least electrified countries in the world, and could benefit from clean energy from solar or wind.

“For off-grid communities, where diesel generation is the default source of electricity, the savings to our customers are significant. Businesses can expect about a 30% reduction in their monthly energy costs by switching from diesel to solar mini-grid electricity,” said Sinha.

Husk has to date raised $40 million from investors, including the Shell energy company and the Dutch Development bank FMO. The startup, which also provides financing for household and commercial appliances, was recognized last year by the 2021 Renewables Global Status Report as the only mini-grid developer with over 100 community sites in operation.

Baidu’s electric car brand Jidu closes $400M Series A round

Published

on

Once an industry with long development cycles, the automotive space is being upended by China’s tech giants. One can hardly keep up with all the new electric vehicle brands that come out of the country nowadays. Jidu, an electric carmaking company founded by Baidu and its Chinese auto partner Geely only a year ago, said Wednesday it has banked nearly $400 million in a Series A funding round.

The new injection, bankrolled by Baidu and Geely, which owns Volvo, is a boost to the $300 million initiation capital that Jidu closed last March. The proceeds will speed up Jidu’s R&D and mass production process and allow it to showcase its first concept “robocar” — which it classifies as an automotive robot rather than a car — at the Beijing auto show in April. The mass-produced version of the robocar will launch in 2023.

Jidu’s chief executive Xia Yiping previously headed the connected car unit of Fiat Chrysler in the APAC region and co-founded Mobike, the Chinese bike-sharing pioneer acquired by Meituan in 2018.

The rate at which Jidu has moved forward is remarkable but could easily attract skeptics who question its tech’s viability. The speedy cycle, the carmaker explained, is thanks to its strategy of using a simulated prototype car to develop its smart cockpit and autonomous driving systems, rather than testing individual hardware parts in a mass-produced vehicle.

The carmaker said in as short as nine months, it has “tested and proven” the safety and reliability of its Level 4 (autonomous driving without human interaction in most circumstances) capabilities for urban and highway roads.

The EV startup is also putting a big emphasis on branding and fan community, something its competitor Nio is known for. In December, it started recruiting car lovers to join its “Jidu Union” to geek out about cars at online and offline events.

Moving forward, Jidu will be hiring and training talent specializing in autonomous driving, smart cockpits, smart manufacturing and other related technologies.

Resilience raises $45 million for its cancer care startup

Published

on

French startup Resilience announced yesterday that it has raised a $45 million (€40 million) Series A round led by Cathay Innovation. The startup wants to improve the treatment journey when you’re diagnosed with cancer so that you live a healthier and longer life.

In addition to Cathay Innovation, existing investor Singular is also participating. Other funds are joining the round, such as Exor Seeds, Picus Capital and Seaya Ventures. Finally some healthcare investors are rounding up the round — Fondation Santé Service, MACSF, Ramsay Santé and Vivalto Ventures.

I already profiled Resilience in March 2021 so I encourage you to read my previous article to learn more about the company. Co-founded by two serial entrepreneurs, Céline Lazorthes and Jonathan Benhamou, the company wants to help both patients and caregivers when it comes to cancer care.

On the patient side, Resilience helps you measure, understand and deal with the effects and side effects of cancer and cancer treatments. Users can track various data points in the app and find content and information about their illness.

But Resilience isn’t just an app that you use at home. It is also a software-as-a-service solution for hospitals so that they can better personalize their treatments. Resilience has been founded in partnership with Gustave Roussy, one of the leading cancer research institutes in the world.

Practitioners will be able to take advantage of all the data that patients have gathered from the app. This way, cancer treatment facilities understand the patient better and can adapt their care more quickly. Resilience has acquired Betterise to gain a head start when it comes to data-driven cancer care.

The long-term vision is even more ambitious than that. If you talk with a caregiver working for a cancer treatment facility, they’ll tell you they never have enough time.

And it’s even more difficult to keep track of new treatments that are becoming more and more specialized. Resilience doesn’t want to replace doctors. But it wants to help them overcome blindspots.

The result should be better care for patients, as well as more support through the Resilience app. Cancer care is a long and painful process, so anything that can improve this process is a good thing.
