Caught between mounting famine and an ongoing civil conflict, many South Sudanese have been forced to flee into Uganda.

Now, the influx of 1 million people has led to massive resource and food shortages within Uganda,  ABC reports.

Every day for the past year, an average of 1,800 South Sudanese have arrived in Uganda. Another 1 million are displaced in Sudan, Ethiopia, Kenya, Congo and Central African Republic, according to the United Nations High Commissioner for Refugees (UNHCR).

An estimated 85% of Uganda’s South Sudanese refugees are women and children seeking shelter from violence in their home country.

If necessary aid is not sent to Uganda, refugees “may return to South Sudan and take part in the conflict,” Enid Kabasinguzi Ocaya, an official at World Vision, the largest food provider for refugees in Uganda, said in a statement.

A fundraising event hosted by Uganda in June failed to secure the $2 billion in donations needed to support displaced South Sudanese people and the nations that house them.

“With no resolution to the conflict in South Sudan in sight, refugees will continue to flee to Uganda and the humanitarian crisis will only escalate,” Sarah Jackson, an Amnesty International official in Uganda, said.

Refugees in Uganda are normally given plots of land and temporary homes in the hopes they will not only start new lives, but eventually contribute to Uganda’s economy. But without help from the international community, Uganda has become overwhelmed and unable to provide for the new displaced people within their borders.

South Sudan, for its part, has been embroiled in a civil war since 2013, following President Salva Kiir’s accusation that his former vice-president, Riek Machar, plotted to overthrow him.

Despite multiple attempts at ceasefires and peace agreements, the violence has continued to rage.  

"Recent arrivals continue to speak of barbaric violence, with armed groups reportedly burning down houses with civilians inside, people being killed in front of family members, sexual assaults of women and girls and kidnapping of boys for forced conscription," the UN statement read.

Furthermore, a lack of rainfall led to crop failures in 2016, threatening 40% of the population with food insecurity.

The UN and the International Committee of The Red Cross are calling on the international community to donate more to humanitarian assistance so that Uganda can adequately provide for those displaced by poverty, famine, and violence.
