🎉 We have just launched Ulwazi II Knowledge Hub

🥁 Today marks a major milestone as APHRC celebrates its Silver Jubilee. The grand opening of Ulwazi II has been presided over by the Chief Guest, Prof. Shaukat Abdulrazak-P.S State Department for Science Research and Innovation accompanied by #IamAPHRC’s Executive Director, Catherine Kyobutungi, Board Chair, Bunmi Makinwa, and other partners from across the Africa development sector.

The newly launched Ulwazi II is an ultra-modern knowledge hub designed to foster learning, collaboration, innovation, and knowledge exchange, creating a dynamic space for researchers, policymakers, partners, and communities to connect and shape solutions for Africa.

This milestone is not only a celebration of APHRC’s 25-year journey of impact, but also a bold step towards strengthening Africa’s knowledge systems and advancing evidence-driven transformation across the continent.

Celebrating 25 years of Transforming lives in Africa through Research.
#APHRCis25, #IamAPHRC

[APHRC @aphrc]

Ahead of our big day and as part of APHRC’s Silver Jubilee celebrations, we’ve kicked things off with an exciting showcase where staff are sharing insights from their respective areas of work and how they contribute to our vision of transforming lives in Africa through research.

From research and policy engagement to communications, partnerships, and operations, the showcase is a powerful reminder that impact is built collectively.

Today, the #IamAPHRC IDEAMAPS Project team hosted a workshop that brought together city leaders, researchers, and community members to explore how data can improve urban services.

Discussions focused on using community-created data and AI-driven earth observation for better planning in areas such as healthcare access, flood risk, waste management, and road networks.

IDEAMAPS is helping shift the understanding of urban deprivation from labels to data-driven, community-led insights that support decision-making and resilience.
This work is part of APHRC’s efforts to build participatory data systems to address urban challenges in low- and middle-income countries.

This week, the #IamAPHRC IDEAMAPS Project team participated in a City-Wide Validation of five critical urban models shaping the future of our cities and communities: Morphological Informality, Road Access Deprivation, Flood Hazard, Emergency Obstetric Care Access, and Accumulated Waste Piles.

These models are part of APHRC’s efforts under the Integrated Deprivation Area Mapping System (IDEAMAPS) Data Ecosystem project, which is co-developing a participatory data-modelling system to routinely and accurately map deprived areas in cities across low- and middle-income countries (LMICs).

By combining AI analysis of earth observation data with community mapping, IDEAMAPS aims to redefine how urban deprivation (“slums”) is understood, empowering diverse local stakeholders with data-driven, community-informed tools for better decision-making.

Since the beginning of January, six planets have been visible in the night sky at the same time in a fascinating event known as a planetary alignment or parade. This phenomenon, which occurs because the planets orbit the Sun within nearly the same plane called the ecliptic, will continue until February.

Venus, Mars, Jupiter, and Saturn can be seen with the naked eye, while Neptune and Uranus require a telescope for viewing.

To fully experience this celestial spectacle, join us on Saturday, the 25th, at the Waterfront in Karen. Together with @leoskyafrica, we’ll explore the night sky through telescopes and marvel at this incredible phenomenon.

If you can’t make it, don’t worry! You can use apps like Stellarium, Skeye, or Starwalk to navigate the night sky and view the four brightest planets a few minutes after sunset.
