After decades of drought, groundwater is rising across Africa’s Sahel

By / / Good News For Humankind

Water tables across much of Niger have climbed roughly 13 feet, refilling aquifers that farming families rely on for drinking water and irrigation. Lake Chad — a vital source of fish, water, and grazing land for the region — swelled past 9,000 square miles in 2024, nearing its 1960s extent, while 200 million regrown trees are anchoring soil and reviving wildlife habitat. Returning rains and farmer-led restoration are rebuilding food and water security across the region. The catch: the same fierce storms driving this recovery are killing people and destroying homes, and whether the aquifers can outpace a fast-growing population remains uncertain.

Guinea worm disease nears total eradication with just 10 human cases recorded

By / / Good News For Humankind

Guinea worm disease is on the verge of becoming only the second human disease ever eradicated, after confirmed cases fell to a historic low of just 10 worldwide. This ancient parasite, which has tormented humans for millennia, has been reduced by more than 99.9 percent since the 1980s through an extraordinary public health campaign relying entirely on community education, water filtration, and local surveillance — no vaccine or drug exists. The achievement, led largely by the Carter Center and local health workers across sub-Saharan Africa, demonstrates that sustained, community-driven effort can conquer even the oldest and most entrenched diseases.
