M-Pesa is an electronic mobile money platform (e-wallet) used to carry out financial transactions (send, receive, and save money) via a local service provider. It is a low-cost, fast, and safe way to make payments and handle money. To carry out any transactions, an individual has to give cash for their virtually registered account (on their mobile phone) to be credited by an authorized agent. The mobile money accounts do not need to be linked to an account in any financial institution or carry out transactions using an internet connection. Aside from P2P payments, this service also facilitates B2B solutions; people can use it to pay for goods and services.

HARASSMap was founded in late 2010 in the hope of engaging Egyptian society to create a no-tolerance environment towards sexual harassment, in a nation where it was often dismissed or viewed as socially acceptable. It is an online platform that allows victims and bystanders to report sexual harassment incidents instantaneously and remotely, with their exact locations mapped and aggregated to identify sexual harassment hotspots. This is paired with groundwork, with volunteers approaching local security, businesses, and authorities in harassment hotspots as part of HARASSMap's Safe Areas scheme to develop, implement and enforce sexual harassments strategies tailored to their specific urban contexts.

Starting in 2015, SafeBoda created a network of boda-boda drivers to provide a safe, convenient, and stress-free urban transportation experience in Uganda via their ride-hailing app. All SafeBoda riders receive extensive training on road safety, first aid, bike maintenance and customer care to make them the most professional riders on the streets. SafeBoda riders are recognizable by their orange jackets and helmets, and they are also mandated to have a spare helmet for passengers. The app has a cashless payment option – customers can choose to pay either in cash or from the e-wallet attached to their SafeBoda account. SafeBoda also has a rider rating system whereby after a ride, customers have to rate their driver before they can request a new trip.

The proposed incinerator runs on biogas produced by biowaste – ensuring that toxic healthcare waste is safely disposed of (instead of exposed in landfills), leveraging the sheer volume of waste generated by the municipality to power its own electricity grid, and producing liquid organic fertilizer as a second byproduct. As the Municipal Council had no prior experience with biogas, UNDP Sri Lanka and the Kaduwela Municipal Council piloted a first plant to test its feasibility. The pilot plant was completed in 2019, and was capable of processing 10 tonnes of solid biodegradable waste.

An Open Data Transparency Portal was developed, to offer citizens the ability to monitor the financial implementation of government programmes at the federal level. The goal was to increase the transparency of public management, enabling citizens to track and monitor exactly how public money is being used. When the portal was initially launched, it was limited in the amount of information it published - however, over the years, more data analytics have been made available via the portal. A crucial component of the portal is a National Debarment List, which lists contractors which citizens are to be wary of as they have previously been sanctioned for corruption or fraud. Citizen engagement was also encouraged, as the portal had an anonymised feedback channel which provided whistleblowers with a secure platform to share intel on corruption activities. The portal also includes a 'contact us' link which offers members of the public the ability to provide suggestions to improve the portal.

NINA is a platform designed to maximise safety on public transport in the city. Witnesses and victims of harassment cases on public transport can easily report incidents on NINA, now embedded within the Meu Ônibus application, the city’s bus route planner. When users report that they are experiencing or witnessing harassment, security cameras in the bus from which the report is logged from is automatically activated, and footage recorded. The recorded footage is then sent to the Civil Police, who then lead the investigation and identify the harasser. The app also provides its users with information about the nearest Brazilian Women's House, so that victims can formalize their report.

The Sakay apps helps commuters determine the best routes through Manila via a variety of transport modes, as per their personal preferences. By aggregating cartographic and commuting data – including public transport fares and timetables – Sakay allows users to plan their routes in advance. With this ability to avoid congested routes and foresee breakdowns, public transit is made more predictable and seamless for Manilans, making mass transit a more viable option than it tended to be previously (and in turn, reducing congestion on the roads from private vehicles). Importantly, Sakay’s route planning capabilities incorporate options from both formal and informal transport modes, including jeepneys, trains, standard buses, point-to-point buses, inter-provincial coaches (UV Express), shuttles, and the Pasig River Ferry. Commuters may check for instance, how to get from point A to point B using a combination of jeepney and bus travel, ensuring that popular local or informal transport options are legitimized and fully leveraged in the local public transport ecosystem.

At its core, ur-scape is a planning support tool which (i) synthesizes available data and (ii) makes associations, estimates, and proxies to fill data gaps in ‘data-poor’ communities. By synthesizing spatial and social data from varied sources at different scales, ur-scape offers policymakers the ability to fully leverage and make sense of city-level data to develop well-informed solutions. An interactive dashboard presents data and statistics in visual formats, ensuring that ur-scape remains intuitive and straightforward for non-expert stakeholders to use for analysis. It makes use of 3 main functions to help planners enhance ‘sweet spots’ and relieve ‘stress points’ in the city. A ‘Contour Tool’ highlights areas where more than one dataset is available, offering policymakers the ability to plan for specific land uses based on specific criteria – for instance, planners could examine (a) population density data and (b) drainage conditions to identify areas with high flood risk (high density, low drainage). A ‘Reachability Tool’ helps with transport planning, generating the time taken to commute between selected points depending on the chosen mode(s) of transport. This way, planners could simulate new routes virtually before piloting them in the real world. Lastly, a ‘Planning Tool’ offers users the ability to simulate the use of new building materials and elements to study their effects – for instance, on population density, soil fertility, green cover, or construction cost.

In May 2020, UNDP’s Uganda Country Office partnered with Jumia Uganda, a leading e-commerce company, to address this challenge. UNDP Uganda proposed Jumia expand its online trading platform to cater for a new market - the products of informal street vendors. Leveraging Jumia’s present digital and logistical e-commerce presence and infrastructure - including its robust network of motorcycle riders - the collaboration allows customers to place and pay online for orders from informal street vendors, which are then relayed to intermediaries or 'market agents'. The market agents then go to the market to pack these orders, performing quality checks and ensuring the products are hygienically and securely packaged, before sending them to motorcycle drivers for delivery.

In collaboration with the Municipality of Concepción del Uruguay, UNDP Argentina’s Accelerator Lab designed and implemented the Con Vos Network. The Network consists of thirty-two stores of different genres, most of them located between 1.5-2 km from the city centre. Neighbours can obtain help from these shop owners to carry out digital procedures at very low costs, while the shop owners simultaneously strengthen their own digital literacy, whilst acquiring additional income. The Network took a bottom-up approach, providing friendly and efficient community-led support to neighbours with limited digital skills in the midst of the COVID-19 pandemic (and beyond).

MBI Sharing is an electric shareable bikes platform developed by MBI Motors Vietnam, a multinational technology corporation from Korea, that allows users to find any parking lots nearby, pay, unlock, ride, and return the vehicle back to another station close by for a small monthly fee. The e-bike sharing scheme was trialled with approximately 500 e-bikes, 50 stations, and one 24/7 operation centre across the Ecopark, an ecological urban township on the outskirts of Hanoi. This sustainable mobility solution is paired with awareness-raising programmes to inform the public of the importance of green transportation.

NAAEV has developed a cloud application-cum-open connection network, the e-Mobility Cloud Center, that details the exact locations of e-vehicles charging stations in Serbia which use renewable energy sources (green chargers). The information shared also includes distances and navigation instructions to the nearest charger, and possibly more specific details - characteristics of the charger and its plugs, working hours, booking possibilities, payment methods, and other useful data. The initiative also involves the installation of three new green chargers to be connected to the Cloud Centre, increasing the nation's capacity for green EV charging. These efforts help offer EV drivers an environmentally-friend journey from start to end, with the Cloud Center serving as a comprehensive trip planner for EV owners. The Centre is available for convenient access through an Android and web app.

The Eastgate Centre is the first building in the world to mimic termite architecture, using the same techniques to develop a self-cooling system. The Centre is a 9-story biomimetic mixed-use building, designed to exploit energy-efficient and passive climate control mechanisms. The architects used construction materials with a high thermal capacity, enabling the storage and release of heat gained from the surrounding environment. The Centre comprises two reinforced concrete building masses connected with a glass-roofed central atrium; the building's ventilation system redirects hot interior air outward through the brick chimney stacks on top. Smaller vents branch out from the center cores, drawing cool air into the building, while fans are operated on cycled timings to facilitate air movement. The exterior design incorporates balconies and planters built with Zimbabwean bricks and concrete, so as to increase surface temperature. The concrete balconies in particular minimize total heat in the building by limiting the amount of natural light in the interior.

Freetown City Council introduced #FreetowntheTreeTown — a novel tree cultivation programme that leverages digital technologies to track tree planting and create employment opportunities for local youth. Community-based growers can use a smartphone app to create a unique geotagged ID for each tree planted, revisiting that tree regularly to water and maintain it. Verified tree growth is incentivized with mobile money micropayments. In addition, tree IDs can be converted into fungible “impact tokens”, which can be sold and traded by businesses and individuals as part of a voluntary carbon offset scheme. This generates more revenue that supports future tree-planting.

With favourable reception to this idea from the City Council, the Accelerator Lab and OpenMap set forth together to begin a pilot mapping exercise for existing waste management infrastructure - a crucial first step in identifying pain/pressure points in the waste network, and charting the demand and supply of waste infrastructure. Inspired by the Collective Intelligence approach, the team enlisted the assistance of student volunteers and local government officials to explore the town on foot and manually map waste infrastructure onto the crowdsourced map database using their smartphones. In a span of 2 weeks, volunteers remotely labelled 26,000 physical features and developed 20 different map layers relevant to waste infrastructure, including trash sites, buildings, roads, and waterways. OpenMap Development verified the resulting datasets, and members of the community were engaged in data validation exercises to ensure the accuracy of the data – going on recce visits to areas to compare with the produced maps.

• Ghana Code Club is an after-school programme that teaches students computer programming skills. Children between ages 5-17 can join its free computer science programs from schools, community centres, and libraries to learn to programme using visual and text languages such as HTML/CSS and Python to make computer games, animations, websites, and mobile applications. The Club offers training for school teachers to understand the fundamentals of computer programming to become confident in delivering the new computing curriculum and continue the programme in-house with educational activities in the school. The Club also trains teachers and volunteers to become trainers.

TuCalle, an initiative for sustainable urban mobility, was launched in Ciudad de la Costa to improve the urban mobility and coexistenceamong inhabitants by generating more spaces for pedestrians, cyclists, and skaters while reducing vehicle traffic. A specific area waschosen as the area of intervention to test the pilot and a series of participatory workshops with neighbours, school children, cyclists,skaters, and city officials was organised to diagnose key challenges and co-design solutions. The intervention materialised in the formof three discrete ideas for the target area: (i) an inclusive street for active mobility comprising a pedestrian sidewalk and a bicycle-priority mixed-use road with a speed limit of 30 km/h, (ii) a unidirectional section on both sides of the road for the exclusive enjoymentof cyclists and skaters, and (iii) a large pedestrian space with seven crossroads and pedestrian sidewalks, and heavily regulated trafficto allow citizens to reclaim the city whilst improving road safety. 

The Odyssey City Card provides a safe digital mode of economic transactions to residents of Bhubaneswar and reducesdependence on cash. Residents can use the card for digital payment of government fees and taxes, utility bills, transittickets, parking and other city services. The Odyssey City Card involves background integration of systems acrossvarious municipal departments, improving efficiency by providing a common mechanism for commercial and civicpayments across the city. The card can also be used for online transactions, to shop in retail stores with POS machines,and local authorities plan to integrate it into the Intelligent Transit System to be used for intra-city and inter-city bustravel. The success of the solution lies in providing access to cashless means of payment through simpler applicationprocesses and a one-stop-shop for all the residents’ payment needs.

In 2017, a group of city officials first launched an application, and now an SMS-based platform, that enables riders to report harassmentcases they witness or experience on a real-time basis. The SMS is received by the EPMTPQ – Quito’s Transport Authority – controlcentre, who immediately calls the person reporting to learn more about the situation. Simultaneously, the bus driver is notified of theincident, and an alarm is triggered on the bus unit, alerting all passengers that they should be especially vigilant. In addition, the policeor security personnel of the EPMTPQ are made available to intercept the victim and/or aggressor at the next station.

Sponge cities offer a simple natural solution to this urban problem. By shifting away from traditional “grey infrastructure” ofconcrete and, instead, building porous, permeable infrastructure such as green roofs, roads and gardens that mimic natureand absorb and retain rainwater for future use, Shenzhen hopes to reduce flooding while moving towards a more circulareconomy. The city has formulated a comprehensive multi-layer sponge plan and has created a standardised framework tocoordinate urban development with the requirements of sponge infrastructure. 

In 2019, Via launched the app TRON app, facilitating the ordering of angkots in Bekasi, a city in the east of Jakarta. Initially,TRON operated as a point-to-point service, as with standard public buses. However, by adapting its fleet managementsolutions from other similar ventures, Via soon managed to re-mould TRON such that it operated as an on-demand service,experimenting with a more novel approach to public transit instead of duplicating existing efforts. Based on pick-up requests,TRON algorithmically charts dynamic routes and directs angkot drivers and passengers to a suitable pick-up point (a virtual‘bus stop’). This tracking approach allows commuters to avoid walking long distances to find and hail an angkot, whilst driversare also assured of customers. Furthermore, up to 15 people can share a ride, while avoiding the rigidity of fixed public busroutes. To avoid congestion and unsafe conditions at these virtual bus stops, angkots are also scheduled to depart within 1 to 3minutes from each stop. The option to pay for angkot rides using the TRON app itself reduces the hassle of exchanging cashwith drivers. Furthermore, with the economies of scale of such a large-scale enterprise venture, fares on TRON angkots arefixed, and hence often more affordable than the surge pricing rates offered by angkots hailed on roads.

In partnership with Evergreen Labs, a social enterprise working with ve chai on research and upcycling efforts, the Accelerator Lab embarked onefforts to map the waste sector. A Collective Intelligence approach made use of a combination of GPS route tracking efforts and field interviewswith ve chai. Volunteers were tasked to follow ve chai on their daily routes, tracking their stops, activities, and engagements with other actorseither via a GPS device, or by tracing them manually on a physical map. This data helped reveal the entrepreneurial nature of ve chai, most of themworking as individuals to build their own business contacts and networks (whether with household waste providers or waste aggregators). A totalof 221 waste collection points were identified in the study area, and by visualising this data on a GIS platform, UNDP Vietnam was able todemonstrate how well-distributed waste collection services by ve chai were, covering more than 80% of the city’s geographical area. It wasdiscovered that ve chai collect a collect a significant 4.3%-7.5% of the total solid waste generated in the city – when estimates of total recyclingrates in the city were at 8%. 

With these efforts, a tab for groceries from informal markets was published on the existing Tambula web platform, listing some of themost in-demand items to begin with. As essential service providers, Tambula personnel were allowed by the law to bring ordered goodsdirectly from vendors to customers' doorsteps. The platform accepts all of Namibia's most popular digital payments modes fromcustomers, whilst paying vendors directly in cash to assure vendors of direct income - and to avoid steep learning curves for vendorsless well-versed with digital. 

The Virtual Singapore initiative harnesses the potential of 3D modelling to solve urban challenges. It is an ambitious research programme,operating along three strategic thrusts: (i) consolidating research in 3D data, (ii) catalysing the local 3D modelling industry, and (iii) developing anoperational 3D city model and data platform that integrates BIM, 3D GIS, and simulation for planning use by researchers, citizens, and civilservants. At the heart of Virtual Singapore is a 3D city model (thrust iii.) – a dynamic 2D/3D Digital Twin which offers planners and citizens tools toexamine spatial data, test-bed concepts, and observe the impacts of projects in a ‘Virtual Singapore’ before delivery in the real world. With accessto live real-time monitoring data from IoT sensors, decision-making and urban interventions are better informed by accurate spatial data and real-life human behaviour. However, a database that met Singapore’s distinct research needs could not be operationalized without certain preliminaryefforts. As such, the initiative also involved synthesising research on best practices in 3D data acquisition and analysis, and identifying a list oflocal use-cases that would benefit from 3D modelling (thrust i.). Secondly, CityGML, a modelling standard with high ‘semantic richness’, wasidentified and adopted to catalyse the local 3D modelling industry. The government worked with a collective of local firms to train and uplift their3D modelling capabilities along the CityGML standard, developing the local expertise to be able to contract for the Virtual Singapore Twin andother future 3D solutions for the government (thrust ii.). 

The Early Warning System of Medellín and the Aburrá Valley (SIATA) is an integrated environmental assessment and risk management tool thatcombines scientific knowledge, research, and technology to identify and predict natural and anthropogenic phenomena. This innovation providestimely alerts to the region’s inhabitants and municipal authorities. SIATA deploys sensors that feed real-time data on hydrometeorologicalvariables and atmospheric conditions to a central system through which the information is analyzed and shared with the relevant parties. Thedata is also used to create numerical and statistical modelling to understand and identify future risk. To make data accessible, SIATA designed amobile application and website where users can find the weather forecast, receive alerts, view precipitation patterns and access real-timeimages from the camera network. The initiative also integrates a communication and education strategy to increase community awareness andparticipation. 

Quipu Market is a web-based and mobile platform that enables sellers to advertise their products and services, take orders and buy and sell fromother users. This digital marketplace centres on supporting microentrepreneurs living in informal settlements, where strong community networksare already part of the local market dynamics. The platform encourages cashless transactions by setting up a payment system through localtokens that work as virtual currency, allowing commerce to take place in tokens, cash or a combination of both. By utilising the tokens system,people can buy and sell within their neighbourhoods while saving cash for commercial transactions outside their communities. The data onspending and selling patterns collected on the app can then be leveraged to access microcredits and loans. Users can also accumulate points toreceive vouchers for market purchases and offers on public transport cards, construction materials and entrepreneurship workshops. 

Together, these efforts culminated in Secret Grandmère, a social enterprise selling herbal and medicinal teas made from native Mauritian plants.Cultivating native plants helps to protect the many threatened endemic species on the island, whilst the tea recipes help preserve the localpractices of traditional medicine. The tea is produced and packaged by 20 women from the village of Chemin Grenier in a facility powered by solarpanels, which also produce additional electricity to sell to the grid to generate additional income – allowing the tea to be sold at competitivemarket prices. To grow enough plants for production, an innovative buy-back system was devised, where seedlings are sold to an additional 50-verfamilies of independent growers who cultivate the plants organically, and earn income by selling the leaves back to the business. First sellinglocally, the SGP soon helped network and identify opportunities to expand sales overseas. A dehydrator, co-funded by the British HighCommission, was then purchased to improve tea shelf-life and increase production. In 2012, the project was awarded a second grant to fund theinstallation of 48 solar panels, making it the first and only NGO in Mauritius to be appraised for small-scale energy production. 

With these ideas, Batumi City Hall and UNDP embarked together on the Green Cities: Integrated Sustainable Transport in the City of Batumi andthe Achara Region (ISTBAR) project, with support from the Global Environmental Facility (GEF). It sought to promote more sustainable urbantransport practices through ground assessments and pilot projects, to help support longer-term policymaking at larger scales. An initial (i.)Household Mobility Survey assessed daily practices and attitudes towards transport amongst 1,550 families in 78 transport ‘zones’. Based onthese base parameters and on global best practices in transport demand/supply modelling, UNDP and Batumi City co-developed a (ii.) TransportModelling System, which helped determine feasibility and priorities for traffic infrastructure (roads, routes, interchanges) by simulating various commuter choice scenarios. The model informed the development of various (iii.) pilot projects, including new parking strategies, dedicated buslanes, and renovated and expanded bike lane networks. Altogether, these laid the ground for the first (iv.) Sustainable Urban Mobility Plan ofBatumi, a guide for policymakers based on technical mobility industry expertise, combined with the real needs of Batumi residents.

The Smart Citizen Kit is an open-source hardware device offered to citizens, incorporating low-cost sensors which provide citizens withthe ability to measure various environmental indicators. At the heart of the Kit is the Urban Sensor Board, containing modular hardwarecomponents which measure air temperature, relative humidity, noise, barometric pressure, ambient light, and particulate matter (PM).Citizens place the Kit in an outdoor location of their choice – such as a balcony, windowsill, or atop a building – and it detects andstreams the environmental data using WiFi to SmartCitizen.me. SmartCitizen.me is a custom crowdsourced digital map of environmentaldata collected via the use of Smart Citizen Kits – not just in Amsterdam, but now around the world. The Kit has been developed withreproducibility in mind, ensuring that it remains low-cost and accessible even as it scales in use. The Urban Sensor Board is also able toaccommodate the addition of a variety of third party sensors to measure other environmental indicators, such as the Smart CitizenStation, a full solution for low-cost air pollution monitoring. With these extendable capabilities, the Kit serves not only as a sensordevice, but as a potential base solution for more complex urban challenges.
