18.1 Introduction
To give ourselves a framework around which to think about AI for social good, we will be following the UN Sustainable Development Goals (SDGs). The UN SDGs are a collection of 17 global goals adopted by the United Nations in 2015 as part of the 2030 Agenda for Sustainable Development. The SDGs address global challenges related to poverty, inequality, climate change, environmental degradation, prosperity, and peace and justice.
-What is special about SDGs is that they are a collection of interlinked objectives designed to serve as a “shared blueprint for peace and prosperity for people and the planet, now and into the future.”. The SDGs emphasize the interconnected environmental, social and economic aspects of sustainable development by putting sustainability at their center.
+A recent study (Vinuesa et al. 2020) highlights the influence of AI on all aspects of sustainable development, in particular on the 17 Sustainable Development Goals (SDGs) and 169 targets internationally defined in the 2030 Agenda for Sustainable Development. The study shows that AI can act as an enabler for 134 targets through technological improvements, but it also highlights the challenges of AI on some of the targets. When considering AI and societal outcomes, the study shows that AI can benefit 67 targets, but it also warns about the issues related to the implementation of AI in countries with different cultural values and wealth.

Microsoft’s FarmBeats project is an end-to-end approach to enable data-driven farming by using low-cost sensors, drones, and vision and machine learning algorithms ¹. The project aims to solve the problem of limited adoption of technology in farming due to the lack of power and internet connectivity in farms and the farmers’ limited technology savviness. The project’s goal is to increase farm productivity and reduce costs by coupling data with the farmer’s knowledge and intuition about their farm. The project has been successful in enabling actionable insights from data by building artificial intelligence (AI) or machine learning (ML) models based on fused data sets.
+In Sub-Saharan Africa, off-the-shelf cameras and edge AI cut cassava losses to disease from 40% down to 5%, protecting a staple crop (Ramcharan et al. 2017).
+In Indonesia, sensors monitor microclimates across rice paddies, optimizing water usage even with erratic rains (Tirtalistyani, Murtiningrum, and Kanwar 2022).

-Explanation: Healthcare is a critical sector where timely interventions can save lives. TinyML can enable real-time monitoring and predictions, making healthcare more proactive and personalized.
+
+18.2 Agriculture
+Agriculture is essential to achieving many of the UN Sustainable Development Goals, including eradicating hunger and malnutrition, promoting economic growth, and using natural resources sustainably. TinyML can be a valuable tool to help advance sustainable agriculture, especially for smallholder farmers in developing regions.
+TinyML solutions can provide real-time monitoring and data analytics for crop health and growing conditions - all without reliance on connectivity infrastructure. For example, low-cost camera modules connected to microcontrollers can monitor for disease, pests, and nutritional deficiencies. TinyML algorithms can analyze the images to detect issues early before they spread and damage yields. This kind of precision monitoring can optimize inputs like water, fertilizer, and pesticides - improving efficiency and sustainability.
+Other sensors like GPS units and accelerometers can track microclimate conditions, soil humidity, and livestock wellbeing. Local real-time data helps farmers respond and adapt better to changes in the field. TinyML analytics at the edge avoids lag, network disruptions, and high data costs of cloud-based systems. And localized systems allow for customization to specific crops, diseases, and regional issues.
+Widespread TinyML applications can help digitize smallholder farms to increase productivity, incomes, and resilience. The low cost of hardware and minimal connectivity requirements make solutions accessible. Projects across the developing world have shown the benefits:

+18.3 Healthcare
+
+18.3.1 Expanding Access
+Universal health coverage and quality care remain out of reach for millions worldwide. A shortage of medical professionals severely limits access to even basic diagnosis and treatment in many regions. Additionally, healthcare infrastructure like clinics, hospitals, and utilities to power complex equipment are lacking. These gaps disproportionately impact marginalized communities, exacerbating health disparities.
+TinyML offers a promising technological solution to help expand access to quality healthcare globally. TinyML refers to the ability to deploy machine learning algorithms on microcontrollers, tiny chips with processing power, memory, and connectivity. TinyML enables real-time data analysis and intelligence in low-powered, compact devices.
+This creates opportunities for transformative medical tools that are portable, affordable, and accessible. TinyML software and hardware can be optimized to run even in resource-constrained environments. For example, a TinyML system could analyze symptoms or make diagnostic predictions using minimal computing power, no continuous internet connectivity, and a battery or solar power source. These capabilities can bring medical-grade screening and monitoring directly to underserved patients.
+
+
+18.3.2 Early Diagnosis
+Early detection of diseases is one major application. Small sensors paired with TinyML software can identify symptoms before conditions escalate or visible signs appear. For instance, cough monitors with embedded machine learning can pick up on acoustic patterns indicative of respiratory illness, malaria, or tuberculosis. Detecting diseases at onset improves outcomes and reduces healthcare costs.
+A detailed example could be given for using TinyML to monitor pneumonia in children. Pneumonia is a leading cause of death for children under 5, and detecting it early is critical. A startup called Respira Labs has developed a low-cost wearable audio sensor that uses TinyML algorithms to analyze coughs and identify symptoms of respiratory illnesses like pneumonia. The device contains a microphone sensor and microcontroller that runs a neural network model trained to classify respiratory sounds. It can identify features like wheezing, crackling, and stridor that may indicate pneumonia. The device is designed to be highly accessible - it has a simple strap, requires no battery or charging, and results are provided through LED lights and audio cues.
+Another example involves researchers at UNIFEI in Brazil who have developed a low-cost device that leverages TinyML to monitor heart rhythms. Their innovative solution addresses a critical need - atrial fibrillation and other heart rhythm abnormalities often go undiagnosed due to the prohibitive cost and limited availability of screening tools. The device overcomes these barriers through its ingenious design. It uses an off-the-shelf microcontroller that costs only a few dollars, along with a basic pulse sensor. By minimizing complexity, the device becomes accessible to under-resourced populations. The TinyML algorithm running locally on the microcontroller analyzes pulse data in real time to detect irregular heart rhythms. This life-saving heart monitoring device demonstrates how TinyML enables powerful AI capabilities to be deployed in cost-effective, user-friendly designs.
+TinyML’s versatility also shows promise for tackling infectious diseases. Researchers have proposed applying TinyML to identify malaria-spreading mosquitoes by their wingbeat sounds. When equipped with microphones, small microcontrollers can run advanced audio classification models to determine mosquito species. This compact, low-power solution produces results in real time, suitable for remote field use. By making entomology analytics affordable and accessible, TinyML could revolutionize monitoring of insects that endanger human health. From heart disease to malaria, TinyML is expanding healthcare access for vulnerable communities.
-
+
+18.3.3 Infectious Disease Control
+Mosquitoes remain the most deadly disease vector worldwide, transmitting illnesses that infect over one billion people annually (“Vector-Borne Diseases”). Diseases like malaria, dengue, and Zika are especially prevalent in resource-limited regions lacking robust infrastructure for mosquito control. Monitoring local mosquito populations is essential to prevent outbreaks and properly target interventions.
+
+“Vector-Borne Diseases.” https://www.who.int/news-room/fact-sheets/detail/vector-borne-diseases.
+Traditional monitoring methods are expensive, labor-intensive, and difficult to deploy remotely. The proposed TinyML solution aims to overcome these barriers. Small microphones coupled with machine learning algorithms can classify mosquitoes by species based on minute differences in wing oscillations. The TinyML software runs efficiently on low-cost microcontrollers, eliminating the need for continuous connectivity.
+A collaborative research team from the University of Khartoum and the ICTP is exploring an innovative solution using TinyML. In a recent paper, they presented a low-cost device that can identify disease-spreading mosquito species through their wingbeat sounds (Altayeb, Zennaro, and Rovai 2022).
+
+Altayeb, Moez, Marco Zennaro, and Marcelo Rovai. 2022. “Classifying Mosquito Wingbeat Sound Using TinyML.” In Proceedings of the 2022 ACM Conference on Information Technology for Social Good, 132–37.
+This portable, self-contained system shows great promise for entomology. The researchers suggest it could revolutionize insect monitoring and vector control strategies in remote areas. By providing cheaper, easier mosquito analytics, TinyML could significantly bolster malaria eradication efforts. Its versatility and minimal power needs make it ideal for field use in isolated, off-grid regions with scarce resources but high disease burden.

18.4 Science
-Explanation: Scientific research often requires data collection in challenging environments or over extended periods. TinyML can empower researchers with real-time data analysis, enabling more efficient and in-depth exploration in various scientific domains.
-
-
+In many scientific fields, researchers are limited by the quality and resolution of data they can collect. They often must infer the true parameters of interest indirectly, using approximate correlations and models built on sparse data points. This constrains the accuracy of scientific understanding and predictions.
+The emergence of TinyML opens new possibilities for gathering high-fidelity scientific measurements. With embedded machine learning, tiny low-cost sensors can automatically process and analyze data locally in real time. This creates intelligent sensor networks that capture nuanced data at much greater scales and frequencies.
+For example, monitoring environmental conditions to model climate change remains a challenge due to the lack of widespread, continuous data. The Ribbit Project from UC Berkeley is pioneering a crowdsourced TinyML solution (Rao 2021). They developed an open-source CO2 sensor that uses an onboard microcontroller to process the gas measurements. By distributing hundreds of these low-cost sensors, an extensive dataset can be aggregated. The TinyML devices compensate for environmental factors and provide granular, accurate readings not possible previously.
+
+Rao, Ravi. 2021. Www.wevolver.com. https://www.wevolver.com/article/tinyml-unlocks-new-possibilities-for-sustainable-development-technologies.
+The potential to massively scale out intelligent sensing via TinyML has profound scientific implications. From ecology to cosmology, higher resolution data can lead to new discoveries and predictive capabilities. Other applications could include seismic sensors for earthquake early warning systems, distributed weather monitors to track microclimate changes, and acoustic sensors to study animal populations.
+As sensors and algorithms continue improving, TinyML networks may generate more detailed maps of natural systems than ever before. Democratizing the collection of scientific data can accelerate research and understanding across disciplines. But it also raises new challenges around data quality, privacy, and modeling unknowns. Overall, TinyML signifies a growing convergence of AI and the natural sciences to answer fundamental questions.

18.5 Conservation and Environment
-Explanation: The planet’s ecosystems are under threat, and timely data can aid conservation efforts. TinyML can provide real-time insights into environmental conditions and wildlife behavior.
-
-
-
-
+TinyML is emerging as a powerful tool for environmental conservation and sustainability efforts. Recent research has highlighted numerous applications of tiny machine learning across domains like wildlife monitoring, natural resource management, and tracking climate change.
+One example is using TinyML for real-time wildlife tracking and protection. Researchers have developed Smart Wildlife Tracker devices that leverage TinyML algorithms to detect poaching activities. The collars contain sensors like cameras, microphones, and GPS to continuously monitor the surrounding environment. Embedded machine learning models analyze the audio and visual data to identify threats like nearby humans or gunshots. Early poaching detection gives wildlife rangers critical information to intervene and take action.
+Other projects apply TinyML to study animal behavior through sensors. The smart wildlife collar uses accelerometers and acoustic monitoring to track elephant movements, communication, and moods (Verma 2022). The low-power TinyML collar devices transmit rich data on elephant activities while avoiding burdensome Battery changes. This helps researchers unobtrusively observe elephant populations to inform conservation strategies.
+
+Verma, Team Dual_Boot: Swapnil. 2022. “Elephant AI.” Hackster.io. https://www.hackster.io/dual_boot/elephant-ai-ba71e9.
+On a broader scale, distributed TinyML devices are envisioned to create dense sensor networks for environmental modeling. Hundreds of low-cost air quality monitors could map pollution across cities. Underwater sensors may detect toxins and give early warning of algal blooms. Such applications underscore TinyML’s versatility in ecology, climatology, and sustainability.
+A survey on how TinyML can be used to solve environmental issues has been published by researchers from Moulay Ismail University of Meknes in Morocco (Bamoumen et al. 2022). However, thoughtfully assessing benefits, risks, and equitable access will be vital as TinyML expands environmental research and conservation. With ethical consideration of impacts, TinyML offers data-driven solutions to protect biodiversity, natural resources, and our planet as a whole.

18.6 Disaster Response
-Explanation: Natural disasters can have devastating effects, but early warnings and efficient post-disaster management can mitigate their impact. TinyML can enhance these systems, making them more responsive.
-
-
+In disaster response, speed and safety are paramount. But rubble and wreckage create hazardous, confined environments that impede human search efforts. TinyML enables nimble drones to assist rescue teams in these dangerous scenarios.
+When buildings collapse after earthquakes, small drones can prove invaluable. Equipped with TinyML navigation algorithms, micro-sized drones like the CrazyFlie can traverse cramped voids and map pathways beyond human reach (Duisterhof et al. 2019). Obstacle avoidance allows the drones to weave through unstable debris. This autonomous mobility lets them rapidly sweep areas humans cannot access.

+
+Crucially, onboard sensors and TinyML processors analyze real-time data to identify signs of survivors. Thermal cameras detect body heat, microphones pick up calls for help, and gas sensors warn of leaks (Duisterhof et al. 2021). Processing data locally using TinyML allows for quick interpretation to guide rescue efforts. As conditions evolve, the drones can adapt by adjusting their search patterns and priorities.
+
+Additionally, coordinated swarms of drones unlock new capabilities. By collaborating and sharing insights, drone teams achieve a comprehensive view of the situation. Blanketing disaster sites allows TinyML algorithms to fuse and analyze data from multiple vantage points. This amplifies situational awareness beyond individual drones (Duisterhof et al. 2021).

IEEE.
+Most importantly, initial drone reconnaissance enhances safety for human responders. Keeping rescue teams at a safe distance until drone surveys assess hazards saves lives. Once secured, drones can guide precise placement of personnel.
+By combining agile mobility, real-time data, and swarm coordination, TinyML-enabled drones promise to transform disaster response. Their versatility, speed, and safety make them a vital asset for rescue efforts in dangerous, inaccessible environments. Integrating autonomous drones with traditional methods can accelerate responses when it matters most.

+In 2020, Harvard University, Columbia University, the International Centre for Theoretical Physics (ICTP), and UNIFEI jointly founded the TinyML for Developing Communities (TinyML4D) network (Zennaro, Plancher, and Reddi 2022). This network aims to empower universities and researchers in developing countries to harness TinyML for local impact.
+
+Zennaro, Marco, Brian Plancher, and V Janapa Reddi. 2022. “TinyML: Applied AI for Development.” In The UN 7th Multi-Stakeholder Forum on Science, Technology and Innovation for the Sustainable Development Goals, 2022–05.
+A core focus is expanding access to applied machine learning education. The TinyML4D network provides training, curricula, and lab resources to members. Hands-on workshops and data collection projects give students practical experience. Through conferences and academic collaborations, members can share best practices and build a community.
+The network prioritizes enabling locally-relevant TinyML solutions. Projects address challenges like agriculture, health, and environmental monitoring based on community needs. For example, a member university in Rwanda developed a low-cost flood monitoring system using TinyML and sensors.
+To date, TinyML4D includes over 50 member institutions across Africa, Asia, and Latin America. But greater investments and industry partnerships are needed to reach all underserved regions. The ultimate vision is training new generations to ethically apply TinyML for sustainable development. Outreach efforts today lay the foundation to democratize transformative technology for the future.
18.8 Accessibility
-Explanation: For a more inclusive world, tools and devices need to cater to people of all abilities. TinyML can power devices that bridge the gap, ensuring everyone has access to essential services and experiences.
-
-
+Technology has immense potential to break down barriers faced by people with disabilities and bridge gaps in accessibility. TinyML specifically opens new possibilities for developing intelligent, personalized assistive devices.
+With machine learning algorithms running locally on microcontrollers, compact accessibility tools can operate in real-time without reliance on connectivity. The National Institute on Deafness and Other Communication Disorders (NIDCD) states that 20% of the world’s population has some form of hearing loss. Hearing aids leveraging TinyML could recognize multiple speakers and amplify the voice of a chosen target in crowded rooms. This allows people with hearing impairments to focus on specific conversations.
+Similarly, mobility devices could use on-device vision processing to identify obstacles and terrain characteristics. This enables enhanced navigation and safety for the visually impaired. Companies like Envision are developing smart glasses, converting visual information into speech, with embedded TinyML to guide the blind by detecting objects, text, and traffic signals.
+
+TinyML could even power responsive prosthetic limbs. By analyzing nerve signals and sensory data like muscle tension, prosthetics and exoskeletons with embedded ML can move and adjust grip dynamically. This makes control more natural and intuitive. Companies are creating affordable, everyday bionic hands using TinyML. And for those with speech difficulties, voice-enabled devices with TinyML can generate personalized vocal outputs from non-verbal inputs. Pairs by Anthropic translates gestures into natural speech tailored for individual users.
+By enabling more customizable assistive tech, TinyML makes services more accessible and tailored to individual needs. And through translation and interpretation applications, TinyML can break down communication barriers. Apps like Microsoft Translator offer real-time translation powered by TinyML algorithms.
+With thoughtful and inclusive design, TinyML promises more autonomy and dignity for people with disabilities. But developers should engage communities directly, avoid compromising privacy, and consider affordability to maximize benefit. Overall, TinyML has huge potential to contribute to a more just, equitable world.
-
+
18.9 Infrastructure and Urban Planning
-Explanation: As urban areas grow, managing infrastructure efficiently becomes paramount. TinyML can optimize various urban systems, making cities more livable and sustainable.
-
-
+As urban populations swell, cities face immense challenges in efficiently managing resources and infrastructure. TinyML presents a powerful tool for developing intelligent systems to optimize city operations and sustainability. It could revolutionize energy efficiency in smart buildings.
+Machine learning models can learn to predict and regulate energy usage based on occupancy patterns. Miniaturized sensors placed throughout buildings can provide granular, real-time data on space utilization, temperature, and more (Seyedzadeh et al. 2018). This visibility allows TinyML systems to minimize waste by optimizing heating, cooling, lighting, etc.
+
+Seyedzadeh, Saleh, Farzad Pour Rahimian, Ivan Glesk, and Marc Roper. 2018. “Machine Learning for Estimation of Building Energy Consumption and Performance: A Review.” Visualization in Engineering 6: 1–20.
+These examples demonstrate TinyML’s huge potential for efficient, sustainable city infrastructure. But urban planners must consider privacy, security, and accessibility to ensure responsible adoption. With careful implementation, TinyML could profoundly modernize urban life.
-
+
18.10 Challenges and Considerations
-Explanation: While AI for Good has immense potential, it’s essential to address the challenges and ethical considerations to ensure the technology benefits all without causing harm.
-
-
+While TinyML presents immense opportunities, thoughtful consideration of challenges and ethical implications will be critical as adoption spreads globally. Researchers have highlighted key factors to address, especially in deploying TinyML in developing regions.
+A foremost challenge is limited access to training and hardware (Ooko et al. 2021). Few educational programs exist tailored to TinyML, and emerging economies often lack a robust electronics supply chain. Thorough training and partnerships will be needed to nurture expertise and avail devices to underserved communities. Initiatives like the TinyML4D network help provide structured learning pathways.
+
+Ooko, Samson Otieno, Marvin Muyonga Ogore, Jimmy Nsenga, and Marco Zennaro. 2021. “TinyML in Africa: Opportunities and Challenges.” In 2021 IEEE Globecom Workshops (GC Wkshps), 1–6. IEEE.
+Data limitations also pose hurdles. TinyML models require quality localized datasets, but these are scarce in under-resourced environments. Creating frameworks to ethically crowdsource data could address this. But data collection should benefit local communities directly, not just extract value.
+Optimizing power usage and connectivity will be vital for sustainability. TinyML’s low power needs make it ideal for off-grid use cases. Integrating battery or solar can enable continuous operation. Adapting devices for low-bandwidth transmission where internet is limited also maximizes impact.
+Cultural and language barriers further complicate adoption. User interfaces and devices should account for all literacy levels and avoid excluding subgroups. Voice-controllable solutions in local dialects can enhance accessibility.
+Addressing these challenges requires holistic partnerships, funding, and policy support. But inclusively and ethically scaling TinyML has monumental potential to uplift disadvantaged populations worldwide. With thoughtful implementation, the technology could profoundly democratize opportunity.
18.11 Conclusion
