Today, over half of the world’s population lives in urban areas and that number is expected to increase to 68 percent by 2050. This rapid influx can often put a strain on cities as the need to provide services, infrastructure and housing grows. With so many people expected to move to cities, the need for
sustainable housing increases as well. Thankfully, the development of new technologies, such as the recently developed bio-bricks, might be the future of sustainable building.
Low-Income Urban Growth on the Rise
Ninety-six percent of the world’s urban growth through 2030 is projected to occur in the developing world, and the rate of this occurrence is expected to be highest among low-income populations. Sustainable housing is difficult to access for such populations, and new solutions to
sustainable development must be implemented if the populations increase as projected.
Current housing shortages exist in Asia, Africa and Latin America, are most noticeable in cities and urban areas and are projected to increase. Such a housing lack would mean millions of new homes needed to accommodate for growing populations.
What are Bio-Bricks?
Created by students at the University of Cape Town in South Africa, bio-bricks are bricks made by combining sand and human urine through a chemical reaction. The combination creates a new, strong and sustainable building material; the process has been tested before using synthetic urine, but these bricks are the first to use the real fluid.
How are Bio-Bricks Made?
Bio-bricks are created by colonizing loose sand with bacteria to produce an enzyme called urease. When combined with urine, the urease starts a chemical reaction that produces
calcium carbonate, cementing the sand into place — much like the process that creates coral reefs. The bricks are versatile and can be made into any shape.
The strength of the material also depends on how long the bacteria is allowed to react, which provides the opportunity to create stronger bricks than current, traditional building materials. The bricks are made in molds at room temperature that produce zero greenhouse emissions, unlike kiln-fired bricks which bake at a high temperature and produce large amounts of carbon dioxide.
In addition, the urine used in the process is collected through a waterless urinal, where nitrogen and phosphorous are separated and turned into fertilizer. The remaining liquid is then separated and combined with the sand to create the bio-bricks. It takes about one week for the process to occur and the bricks to be made, and there are no health risks posed by using human waste.
Scaling Up
Before these bio-bricks can be used commercially, infrastructure needs to be put in place to collect urine. Each brick needs between 25-30 liters of the liquid to grow, but the eventual cost of
large-scale collection is unclear as no infrastructure currently exists. BioMASON, the company that tested this process with synthetic urine, had the capabilities of making 5,000 bricks every two days, but needs the appropriate infrastructure to make such potential a reality.
Promising Potential
Once the logistics are worked out, bio-bricks will still face a
social hurdle. Large-scale collection and use of urine are not yet socially acceptable, and the bricks do produce a strong ammonia smell when first made (although it dissipates after about 48 hours).
It may be too early to tell if bio-bricks are the future of sustainable building, but the innovative creation shows great promise. With a slight change in production and better waste capture systems, the future of sustainable building looks promising.

Restrictions on Immigration in Australia
Australia welcomed 208,000 immigrants in 2017, most of whom came from India, China and the U.K. This number was significantly higher than the 85,000 in 1996. Australia’s openness to accepting immigrants can be traced back to when prime minister John Howard was first elected in 1996. Howard emphasized accepting skilled migrants, rather than family migrants as a way to boost the economy. The number of permanent migrants from India was 3,000 in 1996 and 40,000 by 2013. The ration of family migrants to skilled migrants has now been reversed to where two-thirds of Australia’s immigrants are skilled migrants and only one-third are family migrants. Immigration in Australia is changing, and here are some reasons why.
The “Pacific Solution”
In 2001, John Howard implemented an immigration policy known as the “Pacific Solution.” The new immigration policy changed the requirements about where a noncitizen could apply for Australian protection. Previously, one could apply from any of Australia’s migration zone, which is comprised of thousands of islands off the coast of Australia. Under the change, Australia had made it so only people who reached the mainland could claim asylum. Australia’s navy was also given the power to stop migrant boats in the ocean, and the country officially started offshore migrant-processing camps in Nauru and Papua New Guinea (PNG).
In 2013, under the new Prime Minister Julia Gillard, Australia extended the “Pacific Solution” to include the mainland, which basically meant migrants could be sent to the offshore detention facilities regardless of where their ships landed. Until then, those who reached mainland Australia could not legally be sent to Nauru or PNG. Now, asylum-seekers are held in the camps while their claims are processed. Even if they are found to have valid asylum claim, they are not allowed to settle in Australia. Instead, they may settle on Nauru or PNG. Australia even paid Cambodia $42 million to take four asylum-seekers.
Further Restrictions in Immigration
This immigration policy has had its critics, with some organizations claiming that the policy violates human rights. Howard claimed that the program protects Australia from the continuous number of boats and ships trying to land in the country. However, Australia did grant 13,800 visas between 2013 and 2014 to Syrian refugee who had legally applied through its Humanitarian Programme, so the country is clearly open to housing refugees who enter the country legally. In 2017, Australia had received 35,170 new requests for asylum, with most refugees coming from Iraq, Syria and Afghanistan.
In March of 2018, the 457 visas were replaced by the Temporary Skilled Shortage (TSS) visa. The number of primary visas granted for sponsored workers had decreased by 35 percent from July to September in 2017 compared to the same time frame in 2016. This can be attributed to the fact that the employers wanting to sponsor a 457 worker declined, resulting in a one-third reduction in available jobs.
This new policy will also require workers to have two years work experience to be eligible. Jobs deemed to fall under the Medium or Long-Term Strategic Skills list will give workers a four-year, renewable visa with a pathway to citizenship. However, jobs that fall under the Short-Term Skilled Occupation list will be restricted to a two-year, once refundable visa with no pathway to permanent residency.
Clearly, immigration in Australia is changing. It is unclear to what extent Australia will benefit or suffer from these newly implemented restrictions. One thing is for sure, immigrants seeking asylum are going to have a harder time finding it in Australia.

Reinvent the Toilet: Improvements in Sanitation and Hygiene
In November 2018, The Bill and Melinda Gates Foundation hosted the Reinvented Toilet Expo in Beijing. The Expo was the latest iteration of the Reinvent the Toilet challenge that was started in 2011 to help bring clean, safe sanitation to millions of people living in poverty in the developing world. The expo unveiled the world’s first pathogen killing toilet along with small-scale wastewater treatment plants ready for sale to both private and municipal entities. Innovations showcased at the Expo have the potential to greatly decrease human and economic losses because they provide improvements in sanitation and hygiene.
The Importance of Sanitation and Hygiene
Unlike most modern toilets, where waste is flushed away with water, these reinvented toilets separate the waste and water and were designed to be used in areas where no sewer systems exist and to safely reduce waste byproducts With 2.3 billion people worldwide not having access to basic sanitation facilities, it is no wonder that as many as 892 million people defecate in open places like street gutters and bodies of water. This creates serious sanitation concerns as it contributes to the spread of diseases including Hepatitis A, typhoid and polio, as well as intestinal worms, schistosomiasis and trachoma.
Poor sanitation and hygiene along with inadequate water kill as many as 842,000 people in low and middle-income countries each year, affecting children under five the most. According to a 2013 UNICEF report, “2,000 children under five die every day from diarrheal disease, and of these 1,800 deaths are linked to poor sanitation, water and hygiene.” These figures underline the importance of hygiene and sanitation around the world, showing just how important the work done with the Reinvented Toilet Expo is.
Decreasing the Number of Sanitation and Hygiene Related Deaths
The innovative ideas displayed at the Reinvented Toilet Expo aim to significantly decrease the number of deaths from poor sanitation over the course of the next 10 years, especially in urban areas. The World Bank, the Asian Development Bank and the African Development Bank were among the financial institutions that have pledged financial commitments with the potential of reaching $2.5 billion toward urban sanitation projects, which is the largest ever coordinated commitment to urban sanitation.
Currently, 55 percent of the world’s population resides in urban areas, and that number is expected to increase to 68 percent by 2050. This poses a growing challenge for sanitation and hygiene for impoverished people in urban areas where sanitation is at a premium. What limited data exists on urban sanitation suggests that human waste is discharged directly into rivers, lakes and oceans. Making improvement in sanitation and hygiene in urban areas will not only create a healthier population but it also is good for the overall economy.
Better Sanitation Equals a Better Economy
According to The Bill and Melinda Gates Foundation, poor sanitation and hygiene lead to more than $200 billion lost in healthcare costs, decreased income and productivity. The new toilets would greatly reduce that number. The reinvented toilet could represent an estimated $6 billion in the global market by 2030 and could even help open up a new sanitation sector. The World Health Organization reported that every dollar invested in global sanitation could have an average return of $5.50.
Since 2011, the Bill and Melinda Gates Foundation has invested over $200 million towards improvements in sanitation and hygiene and plans to invest another $200 million into decreasing the cost for nations where improved sanitation and hygiene will have the most impact. The continued improvements in sanitation and hygiene will decrease the mortality rate, boost the global economy and have the potential to offer new sources of renewable energy and water.

Top 10 Facts About Living Conditions In Sweden
Located in northern Europe, Sweden has long been heralded by the international community as the embodiment of the Nordic Model– a projection of pragmatic socialism, a bastion of human rights and prosperity for all. But is the country really worthy of the laudatory praise? In the text below, this question will be answered by presenting the top 10 facts about living conditions in Sweden.
Top 10 Facts About Living Conditions In Sweden
As becomes quickly apparent from the article above, Sweden ranks near the top globally in a variety of crucial aspects that help to piece together a thorough picture of living conditions in the country, from its heavily-funded education and health care system to its commitment to upholding democracy, human rights and thwarting income inequality. Nonetheless, significant social strains continue to threaten the country. Sweden’s large refugee intake and changing demography, for example, has been met with a harsh reprimand by some and a rise in crime. If the country fails to address these major issues, its pristine standing in the international communities may be threatened.

How Togo Women Empower Themselves in West Africa
The West African country of Togo has a long history of military rule and had General Gnassingbé Eyadema installed as president from 1967 until his death in 2005. Under his leadership, many human rights abuses were reported and he tightly controlled all aspects of the Togo government.
Soon after General Eyadema died, his son Faure Gnassingbé was appointed as president by the Togo military. However, he yielded to the objections of foreign and domestic protesters and held elections. He won the elections, but the legitimacy of the elections have been a subject of ongoing debate, and his presidency remains controversial because his family has essentially maintained a 50-year-long dynasty in Togo. However, under his rule Togo has demonstrated gradual democratic improvement, holding legislative elections in 2013 and a presidential vote in 2015 that was deemed credible by the international community.
Women in Togo
Although women in Togo are legally considered equal to men, in many ways they are treated as second-class citizens. Togolese women are three times less likely to be sent to primary school, they experience a great deal of discrimination both in searching for work and once they find a job and they must defer to their husbands or brothers when it comes to managing the household. A woman, according to Togolese tradition, can never be the head of her own household. Although women in Togo are positioned as the inferior sex according to the customs of the country and gender discrimination is still prevalent, they still empower themselves by finding unique and creative ways to get their voices heard.
Sexual Boycott
In 2012, a group of Togolese women from an organization called Let’s Save Togo resolved to go on a sex strike in a hope of persuading their male counterparts to take a stand against President Gnassingbé. This sexual boycott, also known as a Lysistrata, was inspired by the Liberian activists who held their own sex strike in protest of violence against women in 2003. Though the Togolese president ultimately did not step down at that point as a result of the strike, it was a notable example of how a nominally disenfranchised group could find a way to speak out and take a stand.
The movement opposing the rule of President Faure Gnassingbé is still very much in effect and Togolese women continue to play a critical role despite the dangers associated with trying to topple such a powerful man. The market women of Togo are largely responsible for financing the opposition to Eyedema, and in return, two of their buildings have been burned down by the government. Though officially a republic, Togo has essentially operated as a dictatorship, with the same family in power for over 50 years, and the Togolese women have had enough.
Plan International Togo
Faced with economic and political challenges in a country that still has a dismal ranking of 134th in U.N. Women’s Gender Inequality Index, Togo women empower themselves with an inner strength and resilience that transcends generations of oppression. The nongovernmental organization Plan International Togo is lending their support with a variety of programs for women and girls. They are providing health education, early marriage prevention and training on citizenship and the basics of government so that women can become more active in the political process.
Togolese women have always been on the front lines of political change, even fighting increased taxation during the period of French colonialism. They continue to make great strides, seemingly undaunted by the limitations that society has tried to impose on them. The way that Togo women empower themselves today would make their predecessors very proud.

Declining Child Mortality in India
Child mortality rate, according to Our World in Data, is defined as the probability that the newborn baby will die before reaching the age of five. It is calculated as the percentage of babies that do die before this age, per 1,000 births. Similarly, the infant mortality rate is the number of children deaths occured before the child reaches his or her first birthday, per 1,000 births. Over the course of world modernization, the child mortality rate has declined greatly, in some areas more than others.
Child Mortality Statistics
In 1990, one in 11 children died before their fifth birthday worldwide, whereas in 2017 that number has more than halved and only one in 26 children died before the age of five. This positive trend can be attributed to improvements in the health field, education and technology, as well as many other factors. The drop in child mortality rate is not exclusive to developed countries, because the developing country of India has also seen tremendous declines in mortality rate over the past several decades.
Child Mortality in India
In India in the 1960s, anywhere between 20 percent and 25 percent of children died before their fifth birthday. This trend continued through the end of the 20th century and at the beginning of the 21st. As of 2015, only 4.8 percent of children are projected to die before they turn the age five. Despite the declining child mortality in India, the country still contributes significantly to the world’s children mortality rate, as it still has negative statistics of 42 deaths per 1,000 live births. The main causes of death for children under the age of five are highly preventable, given the right tools. The most prevalent cause is pneumonia, followed by newborn infections, birth complications and malaria. If more women in India were receiving effective prenatal health care, the numbers would likely drop even more.
The Decline of Child Mortality in India
The declining child mortality in India can be attributed to a number of factors. India saw a great increase in the funding of health care initiatives in the first two decades of the 21st century. The percent of GDP used towards public health was 1 percent in 2004 and jumped to 1.4 percent in 2014, which is a 40 percent boost over the decade. With increased funding towards health care, the country is able to set up set up health infrastructures in areas that did not have any and train community health workers. These trained health workers could serve as the frontline in the mission to improve health in India, and women and newborns would benefit greatly from the extra care.
The elimination of communicable diseases such as polio and tetanus also play a huge role in the declining child mortality in India. There are also plans being put in place for the elimination of more diseases such as malaria and tuberculosis in years to come. While the public health system is not yet in a place to focus on curing diseases, they are aiming for much funding at prevention.
While the declining child mortality in India has been a success for the country thus far, there is, of course, still a long way to go. One of the main areas that could be significantly improved is the time and health care to the women before the child is even born as not enough pregnant women are engaging in prenatal checkups, and many don’t have traditional deliveries in medical institutions. If both these practices were increased, child mortality would drop even more and children would have a better chance at living a healthy life from the beginning. Additionally, the continued improvement of water sanitation and hygiene would improve the lives of all people in India, and certainly contribute to healthier children.
Although the child mortality rate continues to drop in India year after year, the country still needs to understand that this battle is not won. While all citizens must participate in order for the country to continue the positive trend, the government must focus on improving the health care system and devote the attention to the mothers and young children.
