World Water Week began in Stockholm today, bringing together
scientists, elected officials and NGOs to tackle the growing global
water crisis and develop water policy and management initiatives. This
year, the conference is focusing on sanitation, health, and hygiene. 
More than two-and-a-half billion people lack adequate sanitation,
affecting human and environmental health, according to the World Water
Week website. And in many places, wastewater isn't being treated
properly, leaving people with dirty water to drink and use for food
crops. To examine the water crisis in detail, today FSRN takes you to
Somalia, where water's been an issue since the Central government
collapsed with the fall of Siad Barre's government in 1991. In the long
years since, pipes, reservoirs and water treatment plants in south and
central Somalia have been extensively vandalized. Mogadishu's residents
have devised their own informal water distribution systems, but it may
not be enough.  Abdurrahman Warsameh reports.
