Increased flooding caused by climate change impacts is a challenge for many cities both in developing and
developed countries. The existing storm water drainage systems in place have to be physically constructed and
expanded to meet the water run-off challenge. This is an expensive run-off management undertaking for resource
poor countries such as Tanzania. Landscape based storm water management (LSM) is put forward as a
sustainable option to manage storm water run-off and it also addresses water scarcity problems in under-served
urban settlement. However its implementation in cities that are faced with informal residential development is
challenging because among other things, LSM requires land for implementation as well as the collaboration of
different institutions, disciplines and actors. Drawing from data and information obtained from the Water
Resilient Green Cities Africa (WGA) Project in two cities of Africa, this paper explores the planning and
institutional challenges for LSM in Dar es Salaam, a rapidly urbanising city. The paper also presents
opportunities inherent in the process some of which suggest that local institutions offer a critical platform to
collaboratively plan and implement LSM in rapidly urbanising cities.
