In its most basic sense, the concepts behind nanotechnology were formulated by acclaimed physicist Richard Feynman in 1959. Over the past four decades, nanotechnology has made significant advancements and research is expanding as costs are falling. Because of these innovations, nanotechnology is alleviating poverty worldwide.
Using Nanosensors for Water Management in Agriculture
Whether mechanical or chemical, nanosensors use tools to detect minor changes in chemical composition and relay information to change the dynamics of whatever they are monitoring. Nanosensors use artificial intelligence and computing to make adjustments as soon as any predicaments arise. Because of their sensitivity and small scale, nanosensors can detect problems well before other outdated instruments.
In a study for sustainable agriculture, the Organisation for Economic Co-operation and Development (OECD) asserts nanotechnology is alleviating poverty issues such as food insecurity. The OECD study concluded that nanosensors effectively detect changes in moisture across fields of crops. They then automatically adjust the disbursement of water and eliminate water waste while preventing crop losses. Farm machines outfitted with nanosensors detect moisture levels in different crops and suggest better-suited areas for specific crops allowing farmers to change planting patterns or change water allocations to other land plots.
Nanofiltration Membranes Provide Clean Drinking Water
Access to clean water is a crisis that many developing countries face. Usually, the first issue dealt with when fighting poverty is economic development so regulations are not often in place to protect against pollution. In some countries, scarcity of clean groundwater becomes problematic too. However, nanotechnology is alleviating poverty in these areas by providing clean drinking water.
Ghana was the center of a study on the effectiveness of nanofiltration membranes conducted by the International Water Association (IWA) and members of the Indian Institute of Science. The IWA chose to test Ghana’s groundwater due to the high level of pollutants present. During the study, it tested the levels of contaminants, bacteria and natural materials that render water non-potable before and after utilizing nanofiltration membranes.
The results of the IWA study were impressive. Not only did the study determine that nanofiltration reduces pollutants to potable levels, but executed efficiently enough, rural areas could produce enough water for more than 100 households. Ultimately, the conclusion was that nanofiltration was a low-cost solution for drinking water access and production in impoverished rural regions worldwide.
Nanotechnology to Fight Infectious Disease
Most original concepts of nanotechnology’s usefulness focused on medical care. The World Health Organization (WHO) has long been fond of utilizing nanotechnology in health care and fighting infectious diseases. The WHO now recognizes that nanotechnology is alleviating poverty in developing nations through scientific medical breakthroughs.
The first need for nanotechnology to address in developing countries is the diagnosis of disease. Nanobiotechnology allows for an inexpensive option to find multiple dangerous microbes using a single test. These technologies have improved over time and are being used in developing nations to detect most viral and bacterial infections, including tuberculosis.
The COVID-19 vaccine development shows the importance of nanotechnology in the prevention of disease too. The Pfizer and Moderna vaccines use a nanocarrier system designed to activate the immune system to fight COVID-19 by assisting antibody production. The distribution of the vaccine to developing nations is now underway.
The Future of Nanotechnology for Poverty Reduction
Nanotechnology is alleviating poverty in developing nations, and with continued scientific inquiry and advancements in nanotechnology, new applications for poverty reduction will improve. Nanotechnology’s cost-effectiveness and versatility make it one of the most viable technologies to assist in the struggle against poverty.

Around 75% of working Kenyans make their living through agriculture. Being the largest industry in the country, the ability of Kenyan farmers to produce crops is essential for both economic and food security reasons. Agriculture provides food and money to the many farmers and their communities. This vital sector is in danger, with unpredictable climate conditions and the emergence of pests that can decimate entire crops. Artificial intelligence (AI) and mobile smartphones are new resources being used to save the produce of these farmers and the livelihoods of millions of Kenyans. Mobile technology in Kenya has great potential to increase the production of the valuable agricultural sector, keeping millions above the poverty line.
The most common occupations in impoverished nations are in the agricultural sector. Inventors and mechanics around the world have developed new farming technology that will create sustainable agriculture, thereby saving the jobs of millions of subsistence farmers. This will bring an end to global poverty as impoverished communities will be able to increase their income and contribute to local and national economies.
Even though the world is more connected than ever, poverty remains a large problem as many people are left behind. Fortunately, people are using the internet as a platform for change, resulting in unprecedented awareness of global poverty. One example of this is Z Event, a French charity project hosted annually on the live streaming website Twitch. Z Event started with just two people wanting global change. The video gaming event is shattering world records while raising millions of dollars for charity.
Agri-tech, a growing term used to describe Japan’s digital farming technology has greatly advanced farming systems in the country in order to combat a potential water shortage by 2030. Both experienced and inexperienced farmers in Japan are using new technologies to limit the overuse of water and fertilizer, which in turn, is fighting food insecurity and poverty for the entire population. Professor Kiyoshi Ozawa, from Meiji University Kurokawa Field Science Center, summarizes the system, “instead of spraying a large amount of water with sprinklers or the like, fertigation uses narrow pipes to place drops of water and fertilizer at the roots of the growing crops.” Farming innovations in Japan aim to reduce overall poverty in the country.
As the world becomes more technologically advanced and digitally connected, access to technology remains an issue, especially in developing countries. More so, the digital gap between women and men continues to expand, with 300 million fewer women than men using mobile internet,
Charlette N’Guessan, a 26-year-old Ivorian and CEO of the BACE Group based in Ghana, is the first woman to win the United Kingdom’s Royal Academy of Engineering’s Africa Prize for Engineering Innovation. N’Guessan and her team earned £25,000 ($32,000) with the 2020 award for their
Entrepreneurs in Greece are finding ways to battle the financial crisis that has crippled its economy. While entrepreneurship in Greece has predictably prospered in the tourism sector, many new startups are finding success in technology, science and engineering. In 2018, Greece was named the European Capital of Innovation by the European Union and ranked 11 in the world by the Global Innovation Index for science and engineering graduates. Via innovative ideas, Greek startups are helping the economy by creating jobs and stimulating economic development.
