In the Kenyan port city of Kisumu, biological scientist Sheila Kaka Ochugboju tackles the biggest challenge of our era: climate change.

In Kenya, one of Ochugboju's main concerns is the shrinking Lake Victoria, which also borders Tanzania and Uganda. Rich in resources, the lake is the lifeblood of surrounding communities, but a quickly changing environment is forcing people to adapt to new ways of harvesting food and running businesses.

To tackle these issues head-on, Ochugboju works with local women, who she says are most tied to the land and bear the brunt of the crisis.

She and a team of experts also founded the Network of African Women Environmentalists, which aims to address climate issues on all levels.

And as Ochugboju and local women learn more about the area's delicate ecosystem, communities find new ways to support themselves while restoring the nature that surrounds them.
