01 / Our vision

T-SUM is an interdisciplinary and cross-sector collaborative project that aims to identify the conditions under which pathways to sustainable and inclusive transport and land use development can be accelerated in growing cities in the Global South.

T-SUM is grounded in the observation that, in the context of still-low-but-rising levels of motorization, economic growth and increasing social and spatial inequalities, the formulation and implementation of policies, practices and partnerships that can support an accelerated implementation of sustainable mobility structures is an urgent concern for rapidly developing cities.

02 / Objectives

1. To develop a conceptual framework based on alternative development trajectories for (un)sustainable urban transport, drawing on data from cities across the Global North and the Global South.

2. To assemble and co-produce evidence by interrogating urban transport and land use data in two rapidly developing cities in the region, Maputo and Freetown.

3. To initiate participative governance processes to foster new models of development based on a sustainable mobility trajectory, through evidence-based engagement with public and professional stakeholders across levels of governance and sectors.

03 / Impact

T-SUM focuses on the co-production of knowledge between local and international partners in academia, government and the third sector to generate a conceptual framework, evidence base and practice experiences for accelerating sustainable and inclusive mobility development trajectories in Sub-Saharan African cities. 

One of our most important outcomes includes fostering new models of development based on a sustainable mobility trajectory through institutional and governance processes.

T-SUM's main beneficiaries will be the circa 3 million inhabitants from Maputo and Freetown and their periphery. We aim to expand the concepts and methods of this pilot study to other growing economies across the Global South.

Project overview
The Challenge

Cities in developing countries are faced with a choice of repeating the evolutionary mistakes of many of the cities in more developed countries, or ‘leapfrogging’ car-oriented mobility to directly develop more sustainable and liveable cities.
