The world is estimated to have a population of over nine billion people by the year 2050. Such a large number of people would require plenty of essential resources in order to stay alive. Food is one of those essential resources. The U.N.’s Food and Agriculture Organization estimates that 70 percent more food than is produced now will be needed to cater to this new population size.

Overpopulation is a legitimate threat to the well-being of the inhabitants of Earth. Our natural resources are being depleted more quickly; yet at the same time, we require more of those natural resources. We are playing all of our cards and not getting enough back to play again. At any level of overpopulation, people will always need food for sustenance. That is why research in sustainable foods is becoming more popular.

Impossible Foods is an organization set out to create and provide food that tastes great, is good for you and most importantly, does not have a negative impact on the environment or one’s health. Impossible Foods was started by a Stanford University scientist and has since grown in size to 50 scientists. These scientists look at animal products at a molecular level, and then select specific proteins and nutrients from greens, seeds and grains to recreate meat.

Impossible Foods is severing the connection between animals and meat. We have relied on animals to make our food for us in an unsustainable way. Impossible Foods found a better, more humane way of going about creating meat in particular. On its website for example, one can find a picture of an appetizing cheeseburger, crafted only out of plants. That’s right, both the cheese and the burger were made completely out of plants.

Progression in this field of technology can lead to solutions to the foreseeable overpopulation problem. Our current ways of providing food to the masses is becoming inefficient and is under performing. Companies like Impossible Foods are coming up with ways to increase our food production while maintaining the integrity of the land.

wastewaterThe idea behind a technology used to control pollution with algae may not be new but for the first time, scientists have found a way to efficiently implement this unusual system.  Aquanos Energy is now available and aims to produce high-quality water from liquid waste, using minimal amounts of energy.

The key to the advances made by Aquanos Energy lies in addressing algal blooms. Algal blooms are the result of an excess of essential plant nutrients into water. The higher concentrations of these nutrients cause an increased growth of algae and green plants. The term is often used when there is a rapid accumulation in the population of algae in a water system. As more algae and plants grow, others die and the dead matter becomes food for the bacteria. This results in what is often referred to as a “dead area.”

These blooms can be dangerous if the algae involved are toxic, however, researchers have come up with a novel way to control algal blooms and then use them to absorb these excess nutrients before they escape to other parts of the environment.

Researchers were unsure as to why other wastewater with algae treatments did not work in the past. They eventually came to the conclusion that the water which was used to test the methods in the past was simply not dirty enough. The recommendation reached as a result of these studies was that decontamination plants needed to be in shallow ponds and stretch over vast areas of land. Fortunately for people in dire need of fresh water all around the world, these recommended areas can be found in remote areas in developing nations.

Despite the impressive economic growth by developing countries such as India, problems produced by waterborne pathogens still amount to the cause of about 80 percent of illnesses. A huge part of this issue is the lack of wastewater facilities. Only about 20 percent of India’s communities had access to wastewater treatment in the past.

Traditional wastewater treatments require large amounts of oxygen for their biochemical activity. Supplying this amount of oxygen requires mechanical devices to provide air into the reactors to begin cleaning the water. Unfortunately, these devices demand huge amounts of electrical power, to which many developing countries do not have access.

A new technology developed by Aquanos Energy and further improved by World Water Works has succeeded in making conventional wastewater treatment plants available.

The technology’s concept captures the interdependent relationship between bacteria and algae. The process results in a 90 percent reduction in plant energy and reduces the operational costs of wastewater treatment systems by 40 to 60 percent.

The concept was proven effective and successful in a demonstration project and is now being launched in parts of India and Africa.

food security
According to the World Bank, the world’s population is set to reach over 9 billion by 2050. With food security already a challenge, how will agriculture meet the food security needs of a much larger population?

According to Chris Brett, global head of sustainability at Olam International, food security success will depend on what he calls the ‘four A’s’—availability, accessibility, affordability and adequacy.

Availability, says Brett, will depend on smallholders’ access to land rights and financial support. Brett believes that policy-makers should look at ways to encourage lending, and increase the extent to which farmers legally own the lands that they cultivate.

As over 2 billion people depend on smallholder farms for their livelihoods, augmenting the smallholders’ ability to prosper could potentially go a long way to reduce poverty.

Banks, however, are unlikely to lend to farmers in disaster-prone areas. Farmers in such areas face the difficult choice between investing in safe but unprofitable crops, or riskier though potentially more lucrative alternatives.

According to a recent article by Gaby Ramm and Roland Steinmann, agriculture insurance presents a potential solution to the conundrum faced by farmers in risk-prone regions. Pilot study results suggest that insurance can indeed play a role in encouraging farmers to engage in more lucrative practices. In India, farmers with rainfall insurance displayed a tendency to gravitate toward cash crops, which—though vulnerable to rainfall deficits—produce much greater returns.

Furthermore, insurance can also indirectly allow farmers access to more credit, by encouraging lenders to lend with more frequency and confidence. This, in turn, leads to further capital investments.

Smallholders can also benefit from cooperation with large-scale agriculture. According to Brett, cooperation between large-scale and small-scale agriculture can be mutually beneficial, and can increase yields through pre-financing and training in skills such as inter-cropping.

Brett also notes that, while Africa’s agricultural potential is enormous, investments in infrastructure will be necessary for that potential to be fully realized. It is estimated that Africa needs $55 million in agricultural investment to guarantee self-sufficiency.

PAK-Energy
In Pakistan, 16 million families don’t have access to clean-burning fuels for cooking and heating. The result of this is increased health problems, especially for women and children. A solution has been developed by PAK-Energy to help reduce this issue. Ranked in the list of “10 Incredible Tech Innovations from 2014 that will Benefit Humanity” on the ONE website, PAK-Energy knows where the need lies and seems to be working towards a better alternative for people living in Pakistan.

Ali Raza of PAK-Energy has created a small, sustainable domestic biogas unit that produces biogas good enough to take care of a family’s cooking and heating needs. This biogas unit will also help the family save money by reducing the cost of fuel. The other benefits of it include reducing waste production and producing nontoxic organic residues that can be sold later on for fertilizer.

PAK-Energy has a vision that is committed to becoming part of a green revolution for Pakistan. It does this by providing energy solutions that are more cost efficient and better for the community like the one mentioned above.

So what is biogas exactly? Organic waste like animal manure, kitchen waste, agricultural residue and even industrial waste can be turned into biogas. This biogas can be used for cooking, heating, lighting and electricity generation for families. There are also economic benefits to biogas such as employment generation, industrial growth, additional source of income with fertilizer, rural development, low cost product and create a sustainable economy.

PAK-Energy has received a lot of recognition for its progress in helping the poor for example in 2011, it received an invitation from the Prime Minister of Turkey to attend the Global Entrepreneurship Summit. Also within that same year, it one the first prize in the Young Entrepreneurs Business Challenge in Lahore, Pakistan.

So far, PAK-Energy has made a big impact by creating seven pilot projects in Lahore, Pakistan. This helps families save money and it helps the environment as well. As a plan moving forward, PAK-Energy has a goal of 25,000 units to be installed within the next five years.

world food
Global food prices fell to a six-month low in July, according to the United Nations Food and Agriculture Organization.

The FAO’s Food Price Index – which measures price shifts according to the average price of a basket of over 50 food products – measured the average international price of food at 2.1 percent lower than in June. Current levels are the lowest they’ve been since January 2014 and 1.7 percent lower than in July 2013. While global meat prices rose due to higher demand in Asia, prices for grains, oil-seeds and dairy fell. The expected crop production of the United States and South American surpluses drove down the value of soy oil.

“The lingering decline of food prices since March reflects much better expectations over supplies in the current and forthcoming seasons, especially for cereals and oils, a situation that is expected to facilitate rebuilding of world stocks,” says top FAO economist Concepcion Calpe.

The global average price of cereals has dropped 36.9 points since July 2013 while vegetable oils dropped 5.6 points and dairy 17.5 points during the same time period. Sugar and meat prices have risen, however, by 20.1 points and 25.4 points, respectively.

The release of this data comes as Russia has declared a year-long ban on Western food imports in retaliation for Western sanctions against Russia over the Ukrainian conflict. Russia imports 40 percent of its food, and prices within the Federation will likely rise without food imports from the U.S., the European Union and Norway.

Prices in the EU could lower as the ban will decrease overall demand.Yet Calpe does not believe the ban will significantly affect global food prices, saying, “The big losers in this case would be more the consumers in Russia themselves because it means they would pay higher prices. It would increase prices internally in the Russian Federation, but for the rest of the world it would tend to depress the quotations.”

The conflict in Ukraine brought a brief spike in global food prices in March, but experts remain skeptical that the fighting could affect food prices to the extent of the 2008 world food crisis. From 2005 to 2008, global food prices increased by 83 percent – a drastic change that rendered 40,000 million more people unable to afford food. Tens of thousands of citizens found themselves suddenly unable to afford the new prices, demonstrated throughout sub-Saharan Africa, Egypt and parts of Asia.

Economists have since blamed the crisis on decreased levels of production, higher demand from emerging economies, higher energy costs and a new demand for safer agricultural stocks in the wake of the housing bubble.

Still, the decrease in prices comes as good news to those in developing nations who spend a significant portion of their income on food. As the FAO points out, 842 million people worldwide still suffer from chronic hunger, but the organization continues to strive “…to make sure people have regular access to enough high-quality food to lead active, healthy lives.”

sequence-african-rice-genome
As the Earth’s population is predicted to increase to more than nine billion people by the year 2050, researchers have made a step forward in solving the “Nine Billion People Question.” The question poses the possibility of a lack of natural resources as a result of rising population growth. Through successfully sequencing the complete genome of Oryza glaberrima (African rice), scientists and agriculturalists will be better able to understand the crop’s growing patterns and this could allow for the development of modified rice varieties equipped to handle environmental hurdles.

Rice, which feeds half the world, is often deemed the most important food crop. In fact, scientists predict that  come the expected nine billion mark  “hardy, high-yield” crops such as African rice will become increasingly crucial for human survival in conditions of extreme climate change.

While the number of people needing to be fed continues to grow by at least two billion over four decades, crop production is nonetheless halting due to climate change, resulting in a scary combination. Rod A. Wing, who led the recent sequencing effort, also helped sequence the genome of Asian rice, which has since enabled the discovery of hundreds of “agriculturally important genes” which can allow for faster breeding cycles and even the ability for the plant to survive up to two weeks under water during flooding.

The genome for the wild tomato, Solanum pennellii, has also recently been published. Despite the fact that it is poisonous, the wild tomato can better tolerate dry conditions and can handle saltier soils. The genome will ensure that new varieties bred do not include any of its poisonous genes. The tomato, along with African rice, are two prominent examples of food modification that could save millions of human lives.

“The idea is to create a super-rice that will be higher yielding but will have less of an environmental impact,” said Wing, including varieties which could require less water, fertiliser and pesticides. African rice, which has already been crossed with Asian rice to produce new variations known as NERICA, independently selected many of the same genetic traits as its cousin. By developing types of rice which can hold Asian rice’s high yield and African rice’s high tolerance, scientists may have just found the answer to their original “9 billion” question.

palm weevil
To many in the developed world, insects are nothing more than a 
nuisance. They ruin perfectly fun summers, spread dangerous diseases and can wreak havoc on crop production. They are pestilent almost anywhere, but in some tropical and sub-tropical areas, insects are diverse, plentiful and an excellent source of protein.

One such bug, the palm weevil, is even considered to be a super food by the standards of the Food and Agricultural Organization (FAO). Now a new social enterprise is working to commercially farm the nutritious bug to combat food insecurity.

Aspire, a startup social enterprise that won the prestigious Hult Prize in 2013, is looking to bring insect-based meals to the impoverished masses in Ghana, Mexico, Kenya and Thailand. Originally a five-member team of MBA students from McGill University, the group is now growing in size and has an official partnership with the FAO.

In Ghana, the palm weevil is a culturally accepted staple of the Ghanaian diet, but commercial production of the insect is nonexistent. At the same time, vitamin and mineral deficiencies are pervasive in Ghana, and developmental issues such as growth and mental health in children are growing as a result.

The palm weevil offers an interesting solution to the lack of nutrition in the Ghanaian diet. Whereas producing one pound of beef requires 2,900 gallons of water, 25 pounds of feed and 1,345 square feet of land, producing one pound of crickets (similar to producing palm weevils) requires only one gallon of water, two pounds of feed and 134 square feet of land. Insects like the cricket and the palm weevil are much more cost effective to farm and offer comparable levels of protein to beef production.

But unlike beef, palm weevil protein is also rich in essential micronutrients like iron, zinc, potassium and phosphorous. Growing commercial volumes of the bug for food production is cheaper than growing beef, offers more vitamins and minerals and can promote food security in Ghana quite effectively.

Mohammed Ashour, one of the founding members of Aspire, says farming the insect is easy and straightforward. “The process of farming itself isn’t overly complicated. Someone who is uneducated but industrious can do it and get it up and running in a short amount of time,” Ashour told CNN.

The enterprise is in its earliest stage, having only started in 2013. It will need to grow substantially and learn from its current projects to impact food security globally. Entomophagy, the human consumption of insects for food, is as old of a practice as humans themselves. Perhaps economizing the practice is the way to promote stable and nutritious diets for the world in the future.
