Letoyie Leroshi walked for five days in search of water. The rivers in Samburu County, Kenya, were dry after three years of little rain.

Then, Leroshi, a cow herder, found a small wet area of sand on a dry river bottom. He brought a group of fellow herders to the site to help dig. They hit water, and the young men broke into a happy song.

This water, known as groundwater, could be very helpful in an area dealing¹ with a long period of too little water, or drought.

Drought, groundwater

Climate change is making drought more likely. And people in East Africa and the Horn of Africa do not have the resources to tap groundwater effectively or widely.

For Leroshi and other Kenyan herders, the situation is difficult.

"We had thousands of livestock² four years ago when we experienced short rains," he said. "We have lost hundreds of our cattle and are now worried that if the rains fail yet again, we will lose everything."

Leroshi and other herdsmen carry weapons to protect their animals from thieves.

"Everyone else around is also armed and ready to steal our livestock," he said.

The United Nations water agency estimates that roughly 400 million people across Africa lack access to clean water.

The British nonprofit group WaterAid and the British Geological Survey examined the situation. They found that Africa has enough groundwater for most countries to get through at least five years of drought.

In the coastal³ city of Dar es Salaam⁴ in Tanzania in 1997 drought led people to use groundwater. The same thing happened in Cape⁵ Town, South Africa in 2017. In Ethiopia, hand-pumped wells performed better than all other water sources during a drought in 2015 and 2016.

Africa has 72 large underground areas of water, known as aquifers⁶, that are largely unused, scientists say.

Cautionary tales

Experts also warn people about the danger of misusing⁷ groundwater.

Philip Wandera is a former director of the Kenya Wildlife Service and now with the Catholic University of Eastern Africa. He said groundwater "is not a quick-fix answer for the current drought ... if you have been poor managers of surface water, it means you are likely to do the same with groundwater."

The U.N. reports that just three percent of the total farmed land in sub-Saharan Africa is irrigated⁹. It says only 5 percent of that land is irrigated with groundwater.

Groundwater exploration and building projects are impossible without financing.

Agnes Kalibata, leader of the Alliance for a Green Revolution in Africa, said, "Smallholder farmers who make up most food producers on the continent," badly need irrigation technology.

"Millions of people don't have enough safe, clean water to meet their daily needs, let alone face the climate crisis," said Tim Wainwright of WaterAid in the United Kingdom. He added, "Governments, along with the private sector¹⁰, should use COP27 to agree on investments in responsible groundwater use," along with clear rules for how to use it.

COP27 is the UN Climate Change Conference taking place in Sharm al-Sheikh, Egypt.

The people in Samburu, however, cannot wait much longer. Many herders are almost at the point of losing everything.

"I have lost 30 cows in ... two weeks and if it continues like this we will lose many more. Our women and children are also severely¹¹ affected," said 30-year-old herder Lemerwas Limayo. "Drought ravages¹³ all living things."
