Water Security & Climate Resilience Visualization Challenge: Transforming Data into Actionable Insights for Tanga and Mwanza Cities

2025

The visualization challenge focuses on addressing critical water security and climate resilience issues in Tanzania’s rapidly growing urban centers, particularly Mwanza and Tanga cities, which face significant flooding risks, inadequate wastewater management, and environmental pollution due to industrial effluents.

By utilizing flood data from Mwanza’s Mirongo River and wastewater data from Export Processing Zones, managed through the Climate Risk Database (CRD), the challenge aims to support informed, climate-resilient water management decisions. Participants will develop key technical skills such as geospatial data analysis, GIS mapping, and data visualization; analytical abilities including problem-solving and pattern recognition; communication competencies like visual storytelling and stakeholder engagement; and collaborative skills that promote multi-stakeholder coordination and knowledge transfer.

Emphasizing innovation and impact, the challenge encourages solution-oriented thinking, policy relevance, sustainability planning, and technology integration to transform data insights into practical recommendations. Ultimately, this initiative fosters student-industry cooperation to enhance data-driven decision-making and contribute to sustainable urban development and climate resilience in Tanzanian cities.

General Guidelines

Data Visualisation Challenge is an opportunity for students and young professionals to turn raw data into powerful visualization solutions that highlight climate risks and urban resilience. By working with open datasets and user-friendly tools, participants will learn how to transform information into maps, charts, and interactive visuals that can support better decision-making. The challenge encourages creativity, collaboration, and the use of open-source technologies, while building practical skills that are highly relevant in today’s data-driven world.

Geospatial Data

All the data can be downloaded from the Climate Risk Database. Or you can contact your mentors from the University partners who can help you on how to get the needed data.

Preferred Softwares

Under this visualisation challenge, you are allowed to  use any open source softwares to make your visualisation. Here we list few softwares: Data StudioLeafletMapboxQuantum GISGeonodeU Map, and or Open Refine.
