The mass transit system in Dar es Salaam, capital of Tanzania, cost $150 million and provides transport connections cutting commutes by 2 hours for 400,000 people. 
Dar es Salaam has population 6 million and has grown eightfold since 1980. Four of five people live on the sprawling fringes in informal settlements that take a commute of over 2 hours to city centre. Dar es Salaam has chosen a bus system with dedicated lanes and areas instead of a metro which is costlier to build. The city has only four arterial roads with 2 lanes each way. Most of the growth is on the periphery and unplanned. The Dart System now in place separates the bus lanes from other traffic to reduce stoppages. The average journey from the centre to the terminus at Kimara is now down from 2 hours each way to 45 minutes.saving 50 hours each week for the average bus passenger.

As this report in WSJ shows underreporting of coronavirus cases is a serious problem for Africa, and the figures from Africa's CDC, part of the African Union, do not show the magnitude of the problem. It shows that health workers in places from Yaounde in Cameroon to Dar es Salaam in Tanzania, to cities in Somalia, are reporting a situation quite different from what the CDC shows, with hotspots emerging in some places with little in the way of resources.

Only 1 million tests have been done and half are in SOuth Africa and Ghana. WIthout the testing it is hard to know how many cases there are. Capetown area in South Africa is emerging as a hotspot and hospitals are expected to be overwhelmed within weeks. Officially Tanzania a country with 56 million has 509 cases and 21 deaths, yet this contrasts with reports from health experts. Cameroon and South Sudan are also possible emerging hotspots in addition to Tanzania says this report in WSJ.

A riverside project on the banks of the Sabarmati in Ahmedabad gives the city of 10 million a new look. The project is similar to ones on the Thames in London and Seine in Paris bringing new park space and areas for of public space for a rapidly growing city. Guardian Cities is looking at 15 new cities with population growing to exceed 10 million by 2035- from Tehran, Iran, to Luanda, Mozambique, Hyderabad, India, Ho Chi Minh City, Vietnam, Surat, India, Kuala Lumpur, Malaysia, Chengdu, China, Dar es Salaam, Tanzania. The way this was done was to develop a self financing model. This was the work of architect Bimal Patel who proposed selling 14% of riverfront land of 200 hectares to recover costs. The Sabarmati Riverfront Development Corporation spent 161 million dollars to build new housing for 11,000 displaced families who worked in squatter type housing on the riverbanks as domestic workers, clothes washers. The riverbed had become for decades a dumping ground for city waste. The goals were to provide access for public to the river front and clean up the water with water treatment plants. Bimal Patel calls the project one of three generations as  will take another three years for new water treatment plants. The Ahmedabad Municipal Corporation bears the cost of about $220 million. The famous Sabarmati Ashram of Mahatma Gandhi lies along this riverfront and it gives this sacred space in India's history, the home of Mahatma Gandhi for many years in the struggle for independence, a healthier, brightened space along the river. ...
