How IVF Could Get Rhinos Off the Endangered Animal List

Before Sudan died in 2018, scientists collected his sperm in hopes of developing an embryo that would carry on the species. In December 2019, eggs from Najin and Fatu were harvested and sent to the same lab as Sudan’s sperm. It is here that scientists toyed with the idea of in vitro fertilization (IVF) for rhinos.

The Supernatural Role of Masks in Nigeria’s Yoruba Tribal Culture

Whether the feminine celebration of the Gelede mask or the spiritual transformation through the Egungun mask, these cultural objects perform an imperative role in the Yoruba people’s religious culture.

African masks have been functionally used for thousands of years. Recognized for their supernatural qualities, they transform wearers into new entities, symbolize animal or ancestor spirits, mythological heroes, or moral values, and can even be a way of honoring specific individuals. Moreover, specific ceremonies and masks act as visual representations of local customs. With a vibrant music and dance tradition, the Yoruba people are known for their notable mask culture. The Yoruba are one of Nigeria’s largest ethnic groups, mainly concentrated in the southwestern part of the country but also found in smaller groups throughout Benin and Togo. For over 1,500 years, they have also been defined by their advanced urban kingdoms, strong economy and unique artistic tradition. Ceremonies are imperative to their way of life; vibrant festivals, rituals and weddings display cultural pride, celebrate history and connect the physical realm to the spiritual. Beyond the symbolic instruments and costumes used during these occasions, masks are also extremely vital due to their mystic transformative qualities.

However, when and how masks are used depends on their corresponding festivals. The Gelede mask, for example, is used during the Gelede dance. This ceremony is performed as a way to pay tribute to the primordial mother Iyà Nlà and recognize women’s role in social organization and development. Retracing the history and myths of the people, the Gelede takes place annually after harvests and during times of drought and epidemics. The masks, adorned with intricate motifs and vibrant colors, are worn as a way to honor “mothers,” or good witches who have power over bad ones, in their efforts to protect the community from negative forces. Individual masks reflect local traditions, such as through unique facial markings or figures included on the masks.

Epa masks are worn during yam harvest festivals by young male dancers as they leap onto mounds. The rigorous movements of this dance indicate the community’s fate over the next year; if the dancer successfully leaps, then all is well, but if not, sacrifices are made to the forces that made him fail. Leading up to these ceremonies, the masks are kept in shrines, where they are fed to increase their power and efficacy. Since they are believed to contribute to the wearer’s success, heavy weight and symbols associated with war are characteristic of these masks.

One of the most important masks in their ritual culture, the Yoruban Egungun masks are worn to worship ancestors. These are used during Odun Egungun or “masquerade” festivals, during which men move through town wearing masks as they embody their ancestors. These masks act as a visual manifestation of those being depicted, offering members of the community the opportunity to strengthen their familial bonds and ask for protection or blessings.

Developed over centuries, ceremonial masks remain a significant part of Yoruban culture. African masks have also become admired in museums worldwide for their intricate designs, but contemporary artists and historians have noted that they are exhibited mostly as ethnography. Moreover, African masks have inspired many well-known European artworks, most notably in Picasso’s 20th-century modernist paintings. This Westernization has helped shape stereotypes around African communities, decontextualizing their current cultural significance. However, as the Yoruba masks demonstrate, festivals recommence every year, and the masks continue to visually represent the community’s rich history and religious tradition.

Cholera Outbreaks: Nigeria’s Struggle with a Reoccurring Epidemic

Poor access to clean water and underdeveloped facilities has led Nigeria to face a decades-long, deadly battle against cholera.

For decades, Nigeria has faced major cholera outbreaks throughout the country, posing a serious threat to public health. The disease, an acute diarrheal infection caused by ingesting food or water contaminated with the bacterium Vibrio cholerae, is a major indication of inequity, as well as a lack of social and economic development in the areas where it forms. Since 1972, cholera has plagued Nigeria in intermittent outbreaks that have claimed thousands of lives, the worst being in 1991, with a high of 59,478 reported cases and 7,654 deaths. Despite numerous attempts by the World Health Organization, the Nigeria Center for Disease Control and the Borno State Ministry of Health to provide support through free cholera vaccines and implement prevention and preparedness, the country continues to fight against large, destructive outbreaks. 

Many factors make Nigeria especially prone to these widespread epidemics, including a lack of access to safe drinking water, a lack of infrastructure necessary for water supply and waste disposal and a lack of health facilities. Particularly in smaller communities and remote villages, sourcing clean water is a challenge that leads residents to dig their own wells. Moreover, during the dry season, these wells dry up and leave individuals only with the more hazardous alternative of shallow streams. Poor weather conditions worsen this significant obstacle to clean water and sanitation. Flooding, for example, increases food insecurity by destroying farmland, creating economic loss, demolishing sanitation facilities and contaminating sources of clean water. Several financial issues, including poor investment, funding allocation and low human capital, in conjunction with already deficient infrastructure and low community participation, also contribute to a lack of secure water infrastructure. Not only does this make for a higher potential of infection, but Nigera’s healthcare infrastructure is also underdeveloped, lacking the medical facilities and supplies necessary to treat those infected with cholera. Limited medical equipment and supplies, as well as a lack of internet connectivity, make it extremely difficult to heal patients and facilitate important reporting of cholera data. 

These issues remain significant and continue to threaten the lives of Nigeria’s citizens. This is exemplified by the country’s most recent outbreak in 2024, which saw about 11,000 recorded cases and 359 deaths in October that year. Intense rains throughout the year led to widespread floods and dam breaks across Nigeria, weakening water infrastructure, destroying farmland and leaving many homeless in damaged areas, overall causing a large part of the country to be vulnerable to diseases like cholera. This most recent epidemic was met with policy and prevention program recommendations in the hope of impeding future spreads, the most critical of which being Water, Sanitation and Hygiene services. These accelerate and sustain access to safe water, sanitation services and good hygiene practices, all of which are the main deterrents of cholera spread. While this strategy proved effective when instituted by the Nigerian government during the 2018 outbreak, it still requires increased government funding and outside investment to remain effective. Public health and safety continue to endure disadvantages, as the threat of cholera looms over the country. 

GET INVOLVED:

For those looking to get involved in supporting the fight against cholera outbreaks in Nigeria, check out organizations such as WaterAid, Bread and Water for Africa, Save the Children and The Water Project, groups focused on supplying safe drinking water and sanitation to Nigeria, as well as many other countries in Africa. In addition, organizations like Doctors Without Borders, the World Health Organization, ICAP Global Health and Gavi, The Vaccine Alliance provide medical support to cholera patients in Nigeria and contribute to the development of disease control and prevention.
