LUSAKA, Zambia (AP) — Vice President Kamala Harris has visited a farm outside Zambia’s capital that’s using new techniques and technology to boost its vegetable crop as she highlighted ways to secure food supplies in an age of global warming. She walked past rows of peppers and inspected a drip irrigation system and called it ““an example of what can be done around the world.” In the United States, conversations about climate change usually revolve around replacing fossil fuels with clean energy. In Africa, the focus is on expanding access to food. Rising prices stemming from the Russian invasion of Ukraine have been damaging to poor countries, and global warming is expected to bring more challenges in the coming years.
