Second-generation philanthropist Howard G. Buffett is selling his first African charity effort, the Jubatus Cheetah Reserve, in South Africa’s bush country, as he focuses his efforts on agricultural improvements and combating hunger on the continent, The New York Times reports.

Animal conservation was at the center of Mr. Buffett’s initial philanthropic forays, leading him to build the facility in the late 1990s. He had hoped to establish that cheetahs could thrive on small private reserves, but he said the results have been disappointing.

His emphasis has shifted since his father, the investor and philanthropist Warren E. Buffett, gave each of his three children $1-billion worth of stock for charitable work in 2006. The younger Mr. Buffett’s foundation now concentrates on projects to help poor African farm families, such as providing water treatment and developing drought-resistant crops.
