Although birth rates in developed countries have slowed down dramatically, figures from the United Nations (UN) show that the world's population will hit 9.7 billion by 2050. What's more, much of this growth will occur in underdeveloped and developing countries. These countries lack the infrastructure to cope with rapid population growth, meaning they will require personnel with expertise in transportation, water, waste disposal, and construction.

To learn more, check out the infographic below created by Norwich University's Online Master in Civil Engineering program.

Population Growth Trends

According to the UN, 48 underdeveloped countries, which have been responsible for much of the world's population growth, will continue to experience high birth rates in the future. Out of these countries, 27 are in Africa. With almost all of these countries facing serious financial constraints, they are unlikely to implement sustainable development programs that can spur economic growth. To resolve this problem, these countries should consider collaborating with civil engineers that can help them build and expand health systems, alleviate hunger, build education systems, and enhance the accessibility of basic services. Failure to do so will lead to the degradation of key natural resources including water bodies such as lakes, forests, land, rivers, and wildlife. Over time, population pressure could potentially lead to armed conflict between communities fighting over dwindling and scarce resources.

Exporting Engineering Technology to Underdeveloped Regions

Engineering technologies that have been proven in developed nations can easily resolve some of the major problems facing third world countries. These technologies include:

1. Water desalination

Water desalination technology could be used to resolve water scarcity in drought prone countries. Currently, one in every six people in the world lack access to clean drinking water and demand for this precious commodity is expected to grow by 30% through 2030. Even worse, scientists expect this situation to worsen in the future due to changes in weather patterns that environmental scientists have blamed on global warming.

In Africa, Ghana is one of the countries struggling to satisfy the water demands of its citizens. In order to supply its citizens with fresh water, the Ghanaian government has built a $125 million water desalination plant in Accra. The Accra Seawater Desalination plant has the capacity to desalinate 15.9 million gallons of water that is distributed to over 300,000 residents of the Greater Accra administrative region every day.

2. Food security and rural development

Food security is another major challenge that many underdeveloped countries are facing. Unlike in the west where most people live in urban centers, most people in underdeveloped countries live in rural areas. For this reason, it is more prudent to prioritize rural development to lower poverty levels. These countries should also invest heavily in agriculture because it is the main economic driver accounting for 60% of all employment opportunities in these countries. In Rwanda, for example, the United Nation's International Fund for Agricultural Development (IFAD) has funded 15 rural development programs. As a result, approximately 534,300 rural households are direct project beneficiaries of these programs. IFAD's investments generally aim to solve some of major challenges in Rwanda including food and financial security. Examples of community projects financed by the IFAD include ramping up of food production in irrigated areas and hillsides, export crop farming initiatives, livestock development programs, and development of watershed areas. The IFAD has also funded initiatives that promote rural enterprises.

3. Transportation

Another major problem that underdeveloped countries are grappling with is transportation, including building and maintaining functional transport systems. The most effective way of resolving this issue is investing in urban mobility solutions including light rail and underground public transport solutions. However, transport projects should be useful and sustainable over the long term to ease traffic gridlocks on surface roads. Such undertakings also tend to have a ripple effect on the broader economy including easing accessibility of farm produce (mostly from rural areas), boosting the pool of skilled talent, as well as improving access to affordable food. Nigeria is one of the African countries that has benefited from transport-related projects. This is because the International Bank for Reconstruction and Development (LIBRD) financed the construction of a bus rapid transport (BRT) system in Lagos with the capacity to handle about 200,000 commuters daily. This transport system, which is the only one of its kind in sub-Saharan Africa, has cut daily commute times by 40%.

Upcoming Development Projects

Another project that is bound to boost the prospects of developing and underdeveloped nations is a low-tech and bicycle-based water purification system called Cycloclean. Unlike other devices in this space, the Cycloclean does not require an engine or battery power to operate. This aspect makes it the right tool for addressing the water accessibility challenges facing more than one billion people across the world. The low-tech design approach also means that it can be deployed and used during natural disasters such as flooding. According to the manufacturer, this water purifier requires only one hour to filter enough water for 150 people.

Outside Africa, Nepal has only been able to harness 600 Megawatts of hydroelectric power, which is miniscule considering the country located in the Indian sub-continent has the potential to generate 200,000 MW of hydro-energy. This has forced Nepalese citizens to endure power cuts ranging from 12-18 hours per day. In Africa, universal power distribution is a pipe dream with only 290 million of the continent's 915 million inhabitants connected to the power grid. Fortunately, Africa has the capacity to generate about 283 Gigawatts of energy. Out of this, African countries have only tapped less than 10% of its total energy potential. Nevertheless, projects that can generate 25 GW of energy are under construction across the continent. By 2040, hydropower will account for 25% of all energy produced in Africa.

Conclusion

The world's population is projected to increase by more than two billion people through 2050 with most of this growth occurring in underdeveloped countries. This growth will put a lot of pressure on both natural resources such as water and food as well as transportation systems, especially in urban areas. To deal with these challenges effectively, third world countries should partner with civil engineers who can help them achieve food security, ease transport chaos and boost food production.

Billions of people wake up every day trying to solve the world's problems. It's an amazing thing.

But the world is still filled with problems. Some are extreme (climate change, terrorism), some are just annoying (traffic, storage).

We back entrepreneurs tackling these problems. They usually come to us with a business or an idea. But it's also on us to share what we see as problems that need solving, hoping to spur ideas.

Here's a list of problems we'd like to see solved - and perhaps businesses we'd fund. (This list will be updated.)

1. Low-cost, reliable internet access. More than 34 million Americans don't have access to high-speed internet. It's not even available. And more than 25 million can't afford high-speed internet. So 60 million Americans aren't using high-speed internet in their homes, which is about equal to the combined populations of California and Texas. This is absurd. We're investors in Tazca-Connects, which is running full speed at this problem. But we'd love to see it taken seriously by a greater number of companies and regulators.

2. Next-gen children's toys. Wired Magazine once ranked the top toys of all time: Stick, box, string, cardboard tube, and dirt. This will be true 50 years from now. But if you've ever watched a three-year-old masterfully operate an iPad, you know how much potential kids have with technology. Parents, however, tend to limit or ban screen time out of fear of rotting their kids' brains. That fear comes from a rational realization that most technology doesn't foster creativity and dexterity the way a sick or string does. It's time to change that. Kids grow up in a world dominated by technology and they should be exposed to it from the time they're babies.

3. (Ambitious) Low-energy, low-cost, scalable, desalination. I have a feeling the person who figures this out will be one of the heroes of the 21st Century.

4. Traffic lights. Seriously, someone please make a better traffic light and convince municipalities to buy them. Few moments remind you of your life slipping away than sitting at a red light when no cars are crossing the other way.

5. Civic engagement tools to hold politicians accountable. It's too easy to campaign one way and legislate another. We need something like Change.org, but beyond petitions. Something with teeth, that politicians sign onto and holds them accountable. Apps that cleanly show exactly how government money is being spent could also be helpful.

6. A media company devoted to helping you understand the everyday lives of people outside your socioeconomic group. This has to be done in a way that is engaging enough to get people to want to read it. It's so vital that everyone is able to understand how people of different means - higher or lower - think and live their life.

7. A better way to sell a home. It's insane that people still pay 4-6% real estate commissions. It made a little sense 30 years ago, when all home data was proprietary to real estate brokers. But the Internet has changed that. Stock brokers, travel agents, and insurances salesmen have all seen their margins shrink, if not disappear, due to broader access to information. But realtors are hanging on. Time to shake that up.

8. Khan Academy for adults. Visually teach me something important that I need to know to be a functioning adult. You have three minutes.

9. A cure for social media overload/addiction. I shudder to think how much productivity I've lost over the last decade due to checking Twitter/Facebook/Instagram. I don't want to get rid of these products. But I need a way to check them less often while not feeling like I'm missing out.

10. Analytics that shows how much my daily habits are detracting from my goals. A lot of bad things happen too slow for people to notice until it's too late. Poor diet can lead to cancer and heart disease, but you'd never know that from eating a single cheeseburger. Sleep deprivation takes its toll, but what's one late night going to do? To understand what I'm doing to myself I need to see the cumulative long-term effects of my habits every time I engage in those habits.

11. More efficient home insulation. My thermos keeps my coffee warm for eight hours straight but my house requires a constant gas-burning furnace to maintain humane temperatures. One trend I'm convinced of is that we'll realize the biggest "source" of new energy is increasing the efficiency of our energy-burning stuff.

12. A solution to food waste. Farmers, wholesalers, and consumers waste a ridiculous amount of food. About a third of food is lost or wasted by some estimates, which equates to more than $1 trillion a year. That's some low-hanging fruit (I'm sorry). Just like energy, making better use of what we have can be more valuable than finding new ways to make new stuff.

Lawrence Berkeley National Lab-along with USAID's Global Development Lab, The Lemelson Foundation, The Schmidt Family Foundation, Dalberg Global Development Advisors, The Good Company and OMG-has put together a list of challenges primed for Makers to solve. They call these " Top 50 Game-Changing Technologies for Defeating Global Poverty." These are summarized in a 20-page list, and then fully explored in the full 600-page report. They shared this list "because the problems we all seek to address require urgent action," and they invite the problem-solvers of the world (you, dear readers!) to "begin the conversation."

The top challenge?

The single most needed breakthrough is a cost-effective, energy-efficient method for desalinating water. "Water will be the defining problem of the next 50 years," [Shashi] Buluswar [director of LIGTT, Lawrence Berkeley National Laboratory's Institute for Globally Transformative Technologies] said. "It's probably the single most important thing that needs to be solved."

The researchers analyzed each on its "Difficulty of deployment": (Simple / Feasible / Complex / Challenging/ Extremely Challenging) vs. "Likely time to market" (from "Potential quick wins" to "The most difficult challenges: very complex technologies and daunting deployment hurdles.") In another matrix, they arrange the challenges by commercial potential, in terms of how attractive these would be for industrialized and emerging markets. They are also categorized into nine areas:

1. Global health

2. Food security and agricultural development

3. Education

4. Human rights

5. Gender equity

6. Water

7. Access to electricity

8. Digital inclusion

9. Resilience against climate change and environmental damage

Take a look at how you can help save the world-especially the bolded items that have Makers' names written all over them! (But really, I could have bolded the whole list.)

Despite the dire state of the world today - and the stereotype that millennials' are selfish and apathetic - the generation aged 18 to 35 cares deeply about global issues, and they're determined to tackle them.

In fact, 70% of millennials see plentiful opportunities for themselves and their peers, and 50% believe they can significantly contribute to decision making in their home country.

These insights come from the World Economic Forum's (WEF) annual Global Shapers survey, released this week, which surveyed more than 26,000 millennials from 181 countries to gauge the priorities, concerns, and attitudes of millennials around the globe.

In one survey, WEF asked respondents to name the three most serious issues affecting the world today. For the second year in a row, millennials are most concerned by climate change, followed by large-scale wars and religious conflicts. When asked who should be trusted to fix the issues plaguing the world, millennials said the responsibility belongs to international organizations and themselves.

Below are the top-10 most concerning world issues, according to millennials.
