Meanwhile, the Aga Khan Development Network has overseen projects as diverse as restoring the mud walls of the 14th-century Djingareyber Mosque in Timbuktu (the oldest earthen building in sub-Saharan Africa), repairing key architectural components of the Old City in Afghanistan’s capital, Kabul, and building a huge hydroelectric power network in Uganda that now brings 18 hours of electricity each day to the poor West Nile area, where there had previously been a scant four hours every other day.
