Urbanization in Africa is still a critical issue that preoccupies a good number of governments and getting enough resources is also a big challenge. Solutions are coming in the form of green building solutions - STRAWTEC has recently built factory in Rwanda that produces strawboards panels and the factory has more ambitious projects to improve urbanization in the country with carbon-negative-footprint building materials.
A common characteristic of informal settlements in Cameroon is the lack of indoor lighting during the day. To carry out any productive activities, households have to turn on the lights – for those who can afford electricity - or use kerosene lamps or candles adding to their electricity consumption and accompanying energy-related expenses as well as indoor air pollution. This gadget is an innovative passive lighting technology based on a transparent plastic bottle filled with clean water. It is fitted into the corrugated iron roofs of houses without ceilings.
Sustainable construction techniques present an opportunity for developing countries to lower carbon emissions, lower energy consumption, and from the outset, reduce housing deficit and the cost of living. Many techniques that help lower the cost of building have been tried and tested and proved successful. Green building is slowly but surely being accepted in developing countries.

The Hanging Gardens of Babylon. One of the seven wonders of the ancient world. Attributed to King Nebuchadnezzar II and described by writers of the time as a pensile paradise. Resembling large green mountains constructed of mud bricks; these gardens were the pride of the ancient Babylonians. Legend has it that the King created the gardens for his queen who missed the green hills and valleys of her homeland. Who would have thought that this gesture of affection would set the trend for modern agriculture today? Vertical farming, the act of growing food in high-rise buildings, could change the way we produce food in the future.

Water is one of the great human challenges of our time. As an essential resource for human life, it is staggering that so much of the world should exist without the basic potable water and sanitation services that we know in the developed world. Making a Cleanleap in urban water management practices could facilitate greater access to water for millions of existing city dwellers in developing countries.
The Addis Ababa Light Rail Transit (LRT) project launched in December 2011. The rail is a first in clean initiative in the horn of Africa to enhance public mobility. The light railway of Ethiopia is the first urban metro light rail scheme to be built in a sub-Saharan country outside of South Africa.
