Solution: A Multistripe Laser Triangulation (MLT) scanner has been adapted to scan and accurately show large soil pores (macropores). Using the MLT scanner allows soil hydrologists to predict water movement by comparing soil when it’s dry to when it is saturated with water.

Goals and Objectives: Predicting water movement in soil is important for understanding recharge rates of aquifers, making the management of this resource potentially more effective and efficient. This is especially important for agriculturalists in areas that are plagued by drought. The tool could also help scientists and farmers better understand water runoff, soil erosion, how sediment is added to the land (i.e. deposition), and sedimentation of surface water reservoirs. In addition, it could predict how nutrients are transported within the soil.

Implementation: The International Potato Center (CIP) has worked with Rutgers University and the University of Kansas to develop a tool to predict how water moves through the soil. The scanner was originally developed for engineering purposes and was adapted its use to study soil pores and preferential flow.

The MLT offers advantages to researchers in the field of soil hydrology. The MLT scanner is better at detecting and mapping the soil macroporosity when the soil is dry versus when it is saturated with water. Using math to account for the difference between the two states of the soil, one can make predictions about water movement.

Solution: The Manual Precision Seed Planter and Fertilizer is a hand/foot-powered planter designed for use by women practicing Conservation Agriculture. Precise quantities of seed and fertilizer are dropped by hand into two funnels, which deposit the seeds into two separate holes in the soil.

Goals and Objectives:  The planter is able to plant maize seeds and precise quantities of fertilizer through the surface mulch in all soil types and conditions.

Implementation: The solutions are developed by Triple W Engineering Ltd to improve the poor performance of other Conservation Agriculture planting tools that averaged $80 USD in cost.

This tool will plant through the surface mulch in dry and moist soils. In use, the tool is rocked backward and forward as foot and hand pressure is applied. Prior to dropping a seed, the tool is pushed forward and this creates and maintains the tapered slot in the ground.

One person operates the tool and drops a controlled amount of fertilizer using a small plastic container whose capacity has previously been calibrated for the field and crop requirements.

Details of the Planting Spears: The slots created by two spears maintain a space between seed and fertilizer and prevent direct contact. The spears are made from high carbon steel and resist abrasive wear in sandy soils. The ends of the tubes are flared to ensure the seed and fertilizer are directed into the ground.

The space between the spears increases gradually to reduce friction in the center and prevent blockage by soils when wet. The ends of the delivery tubes are curved to ensure the seeds/fertilizer fall into the holes.

The system delivers both seed and fertilizer to a suitable depth in the moist layer. Using hand dropping ensures that precise amounts of both seed and fertilizer are placed in the optimum positions for most efficient utilization.

Achievements: The resulting precision of seed and fertilizer placement requires about half the normal recommended quantities of seed and fertilizer to be used, allowing for considerable economic savings for smallholder farmers.

Proposed Budget: The Manual Precision Seed planter can be manufactured locally by metal workers for roughly $15 USD.

Problem: The current excessive application of agro-inputs that costs sub-Saharan Africa (SSA) over US $90 billion in health due to human over-exposure and more than US $35 billion on food importation to mitigate threats of food security on the continent. 

Solution: The FiKapSy – short for ‘Flying Knapsack System” is a drone system: a spray boom with rotors for crop dusting precision dispersal of agro-inputs. 

Goals and objectives:  The solution aims to reduce the degradation of the environment and the over-exposure of (mostly) farmers to the harmful synthetic compounds that cause occupational poisoning currently affecting more than 1.1 million practitioners in developing countries like Nigeria.

Implementation: The solution is developed by AMIntegrated Aerial, that builds drones for the task of crop dusting open field farms in rural Africa. For the first time ever while conducting drudgery service of crop dusting, mechanization in rural farms can offer these farmers aerial views of their farms along with other vital information. 

Such information may include the size of a farm; condition of crops; surrounding threats. It gives farmers inexpensive insight into expansion potentials beyond their recurrently cultivated areas for some, in over 20 years. Money can then be confidently spent to clear and cultivate farther reaching ends of their lands with informed decisions. 

Introduction of this inexpensive drone innovative mechanization displaces today's dependency on the failed use of heavy duty, expensive farm tractors for the purpose of agro-input dispersal in developing economies like Nigeria.

Achievements: The solution can help increase utilization of the 874 million hectares of arable land available on the continent from a mere 32% to over 60% in 3 years while reducing soil degradation from the chemical over-application per hectare by 30%.

The solution can help not just African states but countries in other emerging economies looking to tackle food insecurity, chemical proliferation or simply increasing crop yield by providing a more targeted application process of agro-inputs.

Problem: On 10 September 2016, an earthquake with a magnitude of 5.7 Richter scale hit Kagera Region on the shores of Lake Victoria in Tanzania. A total population of 117,721 were severely affected by the earthquake. 17  people died and 440 people were injured. 26,000 houses were damaged rendering over 117,000 people homeless or living in temporary accommodation. As in other disasters, women and children, people living with disabilities were more affected due to loss of privacy and protective space caused by damaged houses. Nearly 70% of primary schools’ students and 36% secondary school students’ access to education was disrupted due to damage to classrooms and lack of toilet facilities in schools.

Solution: The project is a South Africa – Tanzania project initiated to contribute to rehabilitation and reconstruction of schools and health facilities post the September 2016 earthquake which destroyed houses, displaced people and left several communities vulnerable in Kagera, Tanzania. The goal of this project is to restore the learning environment and provide basic health services to the affected communities. It is a South-South Cooperation initiative, launched with the aim to contribute to rehabilitation and reconstruction of schools and health facilities post the September 2016 earthquake which destroyed houses, displaced people and left several communities vulnerable in Kagera, Tanzania. The goal of this project is to restore the learning environment and provide basic health services to the affected communities. The project supports reconstruction and rehabilitation of damaged public infrastructure offered by the government such as schools and health facilities. South Africa has committed itself to continue to support regional and continental processes to respond to and resolve crises, promote peace and security, strengthen regional integration, significantly increase intra-African trade and champion sustainable development in Africa; and continue to promote mutually beneficial South-South cooperation by utilizing engagements with formations and groupings of the South. Based on the commitment above, South Africa has committed to making a financial contribution towards relief efforts in Tanzania related to the rehabilitation of destroyed and damaged infrastructure critical to service delivery such as schools and health facilities. South African expert artisans, engineers and Disaster Management institutions are utilised as far as possible in order to contribute to capacity building and technical and skills transfer to the Tanzanian engineers and artisans.

Problem: Intimate partner violence (IPV) is not a new issue but it is probably more prevalent than most of us think. IPV is a leading cause of death and disability for women worldwide. Around the world, 35% of women are estimated to have experienced either physical or sexual violence at some point in their life. Georgia and South Africa are not the exception in the high IPV prevalence. In South African official statistics reports one in five women experienced physical violence by any partner. When IPV occurs, the survivor or perpetrator’s friends, neighbours, or family members often witness or suspect what is happening. These bystanders can play an important role in IPV prevention and reduction, offering help to a survivor or helping to impose consequences on the perpetrator. Frequently, however, bystanders look the other way, and survivors are left unsupported. 

Solution: The initiative aims to focus on changing the behaviour of bystanders to address or respond to IPV. UNDP Georgia and South Africa, in collaboration with UN Women in both countries, focus on changing the behaviour of bystanders to address or respond to IPV. The initiative aims to equip bystanders with information, skills and tools to enable them to report or act against IPV and to also identify early signs of IPV before it happens and to stop it from happening. This joint study is a great opportunity for two very different countries with a common challenge to learn from each other. In 2017 and 2018, the Behavioural Insights Team (BIT) and the UNDP country teams in Georgia and South Africa and their partners collaborated to apply a behavioural approach to encouraging bystanders’ actions against IPV. The exploratory research indicated that survivors in both countries do not receive sufficient emotional support and they need greater support to access services.

Problem: Rwanda holds the world record for the percentage of females in parliament (61%)and since 2018 Rwanda achieved parity at cabinet level. Despite this impressive report record on female political empowerment, gender-based Violence (GBV) among women and girls remains challenge. At least two in five women (41.2%) experienced physical violence by the age of 15, while more than one in five women (22%) have experienced sexual violence. Estimates show that up to 93% of the victims of physical and psychological abuse were women. The National Gender Status report (2018) indicates that Gender Based Violence (GBV) is a key issue affecting gender equality progress. For example, the Rwanda Demographic Health Survey (RDHS) 2014/15 revealed that 14% of women reported being victims of physical violence within one year preceding the survey. Similarly, sexual and gender based violence (SGBV) prevalence rates are high, with average annual cases reaching 8000. However, SGBV is often not reported, and victims do not receive legal or other assistance.

Solution: The project supports Rwanda to implement systemic approaches to fight GBV and promote gender throughout the country. UNDP Rwanda is one of eight country offices of UNDP in the world that currently hold a Gold Certification in the Gender Equality Seal Initiative! UNDP in Rwanda earned the Gold standard through the implementation of numerous gender-equality promoting activities, both internally and externally which contributed to addressing gender equality gaps. Among the areas where UNDP provided substantive support over the past two decades is the fight against GBV in Rwanda through comprehensive support to the legislative and institutional frameworks as well as programmatic interventions. UNDP Rwanda is the first Country in Africa to implement the egdner equality seal in its three dimensions, the UNDP CO, the public sector and the private sector to ensure that that the laws and policies adopted are effectively implemented at the workplace particularly since many of the previous GBV interventions focused at the community level. In this light, UNDP Rwanda facilitated an exchange visit by a delegation from Ivory Coast, focusing on sharing experiences in fighting sexual based violence. Currently, UNDP is partnering with the Government of Rwanda and the private sector to implement the Gender Equality Seal initiative in the private sector and the public sector which among the six pillars will tackle fighting gender based violence at the workplace. As of today, 38 companies have signed up to join the initiative and 10 of them have started the implementation. UNDP Rwanda is also planning to export this initiative to the media sector where it was proved that around 70% of women journalists face GBV including in newsrooms.

This pilot project aims to promote an innovative concept that can encourage the youngest people to adhere to social entrepreneurship. The project also seeks to illustrate the transformative power of socially innovative companies.


Due to conditions such as insularity, size and income, São Tomé and Príncipe faces several development challenges. Although average annual GDP growth has exceeded 4% since 2012, poverty has not decreased significantly. Unemployment rates (19.7% for women and 9.3% for men by 2015) show a gender imbalance that needs to be addressed. At the same time, the unemployment rate among young people between the ages of 15 and 24 (23% in 2015) is much higher than the national average (13%). However, entrepreneurship among young people is underdeveloped for structural reasons related to the lack of available skills and funding, and the predominance of a culture that promotes the security of public functions over other, less stable livelihood options.


The pilot project "Promoting social entrepreneurship among young people" aims to promote actions that encourage young people to become social entrepreneurs, with particular attention to activities related to the green economy. The project also aims to demonstrate the transformative power of socially innovative companies that seek both financial profit and social benefits through a communication strategy geared particularly to decision-makers from the government, business community and development professionals.

Initially, the project will develop national awareness and leadership to promote a business-oriented approach to social development through a complete package of services (training, financing, peer-to-peer, market access, business laboratories) for the target group (young people interested in social entrepreneurship). These activities will be supported by the establishment of strategic partnerships with international entities specializing in supporting social entrepreneurship (such as Ashoka and Impact Hub).

Secondly, the project will support new and existing social entrepreneurs in developing skills in networks, resource mobilization, maximizing the use of information technologies, as well as in planning, starting and managing business. This stage will also include financial support for on-the-job training and the provision of small grants for potential entrepreneurs of community-based youth organizations, based on targeted local development (focusing on priority areas such as renewable energy or waste management).

To extend its reach and maximize target group engagement, the initiative will be mainly channeled through mobile caravans, mobile structures that will visit rural and urban youth centers. Two types of caravans are planned: the blue caravan, aimed at promoting activities related to the environment, and the green caravan, dedicated to services to support social entrepreneurship. The pilot project will cover the two most populous districts of the country (Água Grande and Mé-Zóchi), which concentrate around 60% of the population of São Tomé. Subsequently, based on the lessons learned, the initiative could be extended to other districts and replicated among other target groups (unemployed adults or women's groups).

South-South Cooperation will play a key role in the project, in terms of training and support in the management of social affairs, whether through access to instructional services or tutoring, in a group or individually, or through virtual sharing of knowledge.

Problem: Farmers' supply of an appropriate amount of chemical to treat the trees in order to control the targeted pest or disease. Too little chemical can result in an outbreak of disease or building up resistance to the chemical. Too much chemical can be hazardous to the operator, cause environmental pollution or result in residue problems on the fruit, not to mention costing extra dollars. Also, farmers need dipper penetration of chemical inside the dense canopy of trees to cure disease.

Solution: Air blast sprayers deliver chemical liquid in the form of mist that are fine droplet sizes which are optimized for delivery of plant protection and plant enhancement chemicals. 

Goals and Objectives: The solution aims to help the growth of crops, reduce the expenditure on manual labour and pesticides consumption, be less time-consuming and ergonomic operation.

Implementation: Airblast sprayers are developed by the Nashik-based start-up, MITRA (Machines, Information, Technology, Resources for Agriculture) for fruits and vegetables in general, and grapes, pomegranates, citrus, mango and apple in particular.

These sprayers can be trailed or mounted on tractors thus being recognized as tractor trailed sprayers, tractor mounted sprayers. Air blast technology is being used in these sprayers to provide sufficient air output for Grape orchards/vineyards. Air blast sprayers produce mist of fine droplet sizes which are optimized for delivery of plant protection and plant enhancement chemicals. Thus they are also recognized as mist blowers. MITRA uses axial fans especially suited for different sizes of canopy of orchard trees and air Assisted Sprayer technology works as atomizer and provided complete coverage in dense canopy of orchard trees with lesser chemical consumption.

Achievements: Airblast sprayers developed are up to 30% cheaper than sprayers available in other parts of the world and take half an hour for an activity that would otherwise require four to five labourers for 5 hours. Hence farmers are claiming up to 40% chemical saving, 80% time and labour saving with 100% coverage and assurance against disease. See M.I.T.R.A customer testimonials here:

Problem: Energy poverty is a huge problem across Africa and renewable energy has a part to play however there are challenges. In crime ridden areas across Africa traditional solar PV solutions have failed. The solar panels are typically stolen within a few months of deployment. The problem is so bad that the Gauteng provincial government was prepared to dismiss solar power as a possible electricity solution for schools and community centres.

Solution: Think of a Turtle moving around, and hiding in its shell when needed. Similarly, the SolarTurtle climbs out of its shell, moves to where the demand for energy is, and then feeds on the rays of the sun to supply the demand – quickly and securely. SolarTurtle has a range of solar energy platforms for community electrification with a special focus on schools. From our flag ship solar containers that fold-away by the press of a button (like a turtle into its shell), to light weight portable kiosks that fold-away and store in-doors for safety. These micro-franchises allow community members to become Turtlepreneurs and address energy poverty at the source of the problem. Our secure energy platforms can also be used for banking, clinics, disaster recovery, cold storage etc. Anywhere you need energy quickly and securely.

Goals and Objectives: The innovation designed for unparalleled security and maximum portability and targets poor and rural communities by introducing a unique solar battery charging station (AKA Solar energy kiosk). Furthermore, our software package manages our franchise and makes training and monitoring easy.

Implementation: The SolarTurtle is an innovation in the form of a micro “electricity dispenser” inspired by traders in Johannesburg who used shipping containers as safe trading spaces and women setting up flip-up kiosk outside schools to sell food and drinks to kids. The SolarTurtle kiosks house solar panels that fold out during the day and retract securely at night, charging powerbank batteries during the day. By using powerbank technology, the storage medium also becomes the distribution medium as customers swap out flat power banks for a full one and continue with their day.

These solar kiosks are assembled off-site then deployed by simply offloading the units and unfolding the panels towards the sun. A unique software package manages the training, monitoring and impact tracking of these small community enterprises

Achievements The Solar Turtle was announced the winner of the inaugural the 2018 Nation Builder Social Innovation Challenge and the 2017 Inventors’ Garage competition.

Problem: The sources of dissolved oxygen in an aqua pond are 4% of the water poured in, 7% mixed in from the surface water, and mainly 89% from the photosynthesis of algae. The growth of a quality bloom is a mystery and it varies from pond to pond. The use of organic and inorganic fertilizers and water exchange does not guarantee a quality bloom. If the source water is polluted there is no immediate remedy. If the algal bloom comprises of green algae and blue-green algae, then it does not readily support live food like zooplankton since the cell walls are made of cellulose and it is not easily digestible by the marine animals. Since the algae are not consumed it persists in the system and one day it will die and crash creating Dissolved oxygen problems.

Solution: ' NUALGI Aqua' is a novel research product that can grow diatom algae on almost any water substrate be it the Sea, high saline water, fresh water, sewage water, effluent water etc.

Goals and Objectives: The solution aims to absorb carbon dioxide and release oxygen due to photosynthesis.

Implementation: Nualgi Aqua was invented by Mr. T Sampath Kumar of Bangalore, India in 2004.

'Nualgi Aqua' contains trace, special and appropriate nutrients that can deliver in a biologically available form. Upon application to the water body in the presence of macronutrients like N, P, K and sunlight, phytoplankton predominately in the form of diatoms, bloom and is soon converted to live food like zooplankton which is attractive to fishes and prawns. The live food boosts fishing and marine resources.

Nualgi Aqua can be used for the following purposes:

  • For growing phytoplankton in the seas to absorb global carbon dioxide and reduce greenhouse gases thereby solving global warming problem.
  • For preventing growth of toxic algal species called Red Tides in the sea.
  • For generation of plankton and live food in aquaculture ponds to boost the growth of prawns and fishes.
  • For treating sewage, polluted and effluent waters by growing diatoms and reducing cod, bod, color, bad odour and growth of toxic algae in ponds and lakes. 
  • For reclaiming and bringing life to lakes, rivers, and water bodies that are polluted by sewage and other pollutants and those in a state of eutrophication.
  • For preventing wild growth of waterweeds, water hyacinth, green algae and blue green algae and other waste plants in lakes, rivers, ponds and other water bodies.
  • Avoiding mass fish kill due to oxygen depletion, growth of toxic algae in ponds and lakes.
  • Removing and crashing out of green and blue green algae from water bodies without affecting the fishes, water animals and portability of the water.

Achievements: The 2015 trials in Queensland, Australia strongly indicate that the use of Nualgi Aqua is a simple, yet effective pathway to manage nutrients and control Blue Green Algae growth.

Problem: Open fire cooking is inefficient, requiring large amounts of wood or charcoal. The huge demand for woodfuel for cooking has led to large scale deforestation across the globe, particularly in Sub-Saharan Africa. Household Air Pollution (HAP) is a major contributor to illness and death in the developing world. Inhaling cook smoke can lead to pneumonia, stroke, ischaemic heart disease, COPD, and lung cancer.

Solution: The ACE 1 is a smokeless biomass cookstove, which burns any type of biomass both cleanly and smoke-free indoors or outdoors and drastically decreases exposure to carbon monoxide (CO) and particulate matter (PM2.5), the primary components of HAP, during cooking. Many households in the developing world also rely on kerosene candles for lighting, which further increases HAP; the ACE 1 includes an LED lamp attachment which provides clean, safe lighting.

Goals and Objectives: The ACE 1 is capable of mitigating many of the problems associated with biomass cooking, as well as offering additional benefits by generating free solar electricity.

Implementation: The solution is developed by the African Clean Energy, a startup founded in Lesotho by Father and son team Stephen and Ruben Walker in 2011 to provide off-grid household energy solutions to people in Sub-Saharan Africa and elsewhere in the developing world.  

The ACE 1 symbiotically combines clean biomass combustion and solar electricity to create an integrated solution addressing customers’ energy needs in a cost-effective way. The product decreases fuel use by 50-85% and it can burn any type of solid biomass, which opens up more fuel alternatives such as agricultural residue or even dried cow dung. It also comes distributed with a 10V/10W solar panel to support device charging and lighting, which for low-income households is a significant financial benefit since basic electricity expenses constitute the bulk of their monthly energy cost. This novel blend of thermal and electric energy generation makes the ACE 1 a unique energy product in its category, as it combines the health, social and environmental benefits of a cookstove with the business model of a solar home system. ACE has sold 26,000 units to date.

How the ACE 1 works:

  • A fan blows oxygen into the chamber through holes at both the bottom and the top. This drives the fire to increase in temperature until it reaches approximately 1000°C. These conditions cause the biomass to gasify.
  • Then the hot gas floats up to the top, meeting more oxygen and combusting completely.
  • The stove will produce as much as 5kW worth of energy, and the outside temperature, though warm after continued use, does not become hot enough to cause injury.
  • When fully charged, the battery will power the fan for over 20 hours of cooking. The battery can also be used to charge a mobile device or run LED lighting and can be boosted using a solar panel.

The ACE 1 has DC and USB ports for phone charging, allowing people without access to grid electricity to charge their phones for free, reducing their costs and increasing their access to ICTs. These ports can also be used to power an LED light included with the stove. Providing basic nano-grid electricity to those who live off the grid not only has benefits at the household level, but also at the level of national development policy. In some cases (such as inaccessible or low-population areas) off-grid solutions like the ACE 1 may be preferable to extending the grid, due to the burden which maintaining electrical infrastructure places on developing countries.

The newest ACE 1 model (to be launched in 2019) includes a microprocessor, enabling it to connect and communicate with smartphones. Concurrently, ACE has developed the Android ACE app, and the combination of the two upgrades the ACE 1 to a ‘smart’ product with new capabilities such as live maintenance alerting or usage data logging. This will make it possible to monitor and record ACE 1 impact, and create unprecedented transparency into the energy consumption habits of poor consumers living off-grid, on whom little data is currently available. This advancement, paired with an upgrade in ACE's current self-reported data collection practices, will allow the company to quantify with precision the environmental and social impact of the ACE 1, as well as well as improve its customer relationship management.

Achievements: The economic impact of the product is impressive. The solution reduces fuel use of about 70 percent, saves 50 percent of costs, and drastically improves the lives of women and children, who do the majority of the cooking.

Based on data collected with 3,000 households in Lesotho, customers interviewed experience an 83% average reduction in monthly energy expenses, 95% of them have stopped purchasing paraffin, and 59% say they no longer need to spend any money on energy.

Budget: The ACE 1 is priced at $100+, but the target market cannot afford to purchase it up front. The ACE 1 is sold on a Pay-As-You-Save (PAYS) model, by which customers purchase it with a 6-9 months microloan, and then pay back the investment using the savings made on monthly energy costs. With this model, ACE is likely one of the only companies in the world that can give $2-a-day people access to a $100+ product.
