Water Resilient Green Cities for Africa (WGA)
PROJECT IS CLOSED
Project period: 2013 to 2019
The project investigated the options for leapfrogging conventional urban water systems to landscape-based systems for increasing the climate resilience of larger African cities and for providing inclusive urban green spaces, and better local planning and governance. This was through developing catchment plans, facilitating a rapid mind-set change through champions, encouraging stakeholder involvements through design charrette and developing low-tech and local material based green technologies.
The WGA project was led by the Department of Geosciences and Natural Resource Management (IGN) University of Copenhagen. Project partner institutes were the Institute of Human Settlements Studies (IHSS) at Ardhi University, Tanzania and the Ethiopian Institute of Architecture, Building construction and City Development (EiABC) at Addis Ababa University, Ethiopia. The project was in close collaboration with representatives from the city administrations and selected communities in Addis Ababa and Dar es Salaam.
The project was organised into four work packages
- Work Package 1
Urban ecology, green spaces; use and livelihoods. Explore the use, functions and livelihood activities in urban green spaces and identify opportunities and barriers for integrating stormwater management in the landscape.
WP leader: Kumelachew Yeshitela (email@example.com), EiABC
- Work Package 2
Stormwater management. Assess the present stormwater management, and design and test local options for LSM in two communities in the two case cities.
WP leader: Antje Backhaus, IGN
- Work Package 3
Urban planning and governance. Identify opportunities and barriers, from an urban planning and institutional point of view, for the adoption and implementation of LSM and its integration in urban planning and how to facilitate inclusive stormwater management.
WP leader: Wilbard Kombe (firstname.lastname@example.org), IHSS
- Work Package 4
Research capacity building and management. Strengthen research capacity in relation to urban climate change adaptation through interdisciplinary and cross-institutional research activities linking theory and practice in a collective learning process specifically related to LSM.

The city of Addis Ababa is the capital of Ethiopia. The population of Addis has been very dynamic. What used to be 443,000 in 1961 has grown 2,7 in 2007 in official figures, however, estimates are that the population has reached 4 million. Addis Ababa has a complex mix of subtropical highland climate. Mid-November to January is characterized by dry winters. The short rainy season is from February to May, with warm temperatures and a pleasant rainfall. The long wet season is from June to mid-September; it is the major winter season of the country. The city is located at 2,200 meters above sea level, at the foot of a mountain range. Many polluted rivers pass by the city. The city experiences both heavy rains and severe drought. Several of the rivers are equipped with dams for the water supply of the city.
The City of Dar es Salaam is Tanzania's largest and richest city, serving as a regionally important economic center. The Dar es Salaam Region had a population of 4,364,541 as of the official 2012 census. Dar es Salaam has a tropical wet and dry climate, with two different rainy seasons. Annual rainfall is approximately 1,100 mm (43 in), and in a normal year there are two distinct rainy seasons: "the long rains", which fall during April and May, and "the short rains", which fall during October and November. Dar es Salaam is located in a river delta. In the rainy season, many areas of the city suffer from flooding and stagnant water. According to researchers, 50% of the problems with flooding, however, a consequence of human impact and 'bad management' such as garbage in drainage channels and streams, lack of infrastructure and so on.
