Kragujevac – renewable energy in district heating

Posted on by erik

‘ENERGETIKA’ Kragujevac, a state-owned company specialising in steam generation and air conditioning, has taken an important step towards environmental protection. In 2021, the old coal-fired boilers were replaced by modern gas-fired boilers, which have been in operation since the 2022/2023 heating season. This conversion has significantly reduced the plant’s environmental impact.

In a further project for the next three years, it is now planned to use the waste heat from a data centre located near the ‘Aerodrom’ boiler house heating plant and feed it into the district heating network using a heat pump. The data centre is planned for two expansion stages and the first has been in operation for less than two years. The currently installed cooling capacity of the 2 modules is 4.4 MW. The expansion of the data centre to 4 modules is expected to double the cooling capacity, which is planned for the coming years. The cooling system is designed for redundant operation.

By using the waste heat from the data centre in Kragujevac and other measures to increase energy efficiency in the hot water system, a significant reduction in greenhouse gas emissions will be achieved.

The initiative highlights the importance of continuous improvement through the exchange of expertise and experiences, ensuring medium to long-term success.

Heat in the City

Posted on by erik

“Heat in the City” is the first Deep Dive learning project run by Connective Cities. Through the “Deep Dive” model, the Connective Cities platform allows municipalities to assign two or three staff spend two to three years as part of an international group focusing on a global issue which is relevant to cities.

2023 was the warmest year since weather records began. Heat accumulated with great intensity in cities, leading to the formation of “heat islands”. In the period from 1986 to 2005 German cities experienced twice as many days with temperatures of 30°C or more than in surrounding areas. Without wide-ranging countermeasures, this number could increase tenfold by 2100. Hot weather particularly affects vulnerable groups such as older people, children, the sick, homeless people and people who work outdoors.

From mid-2023 to mid-2025, six municipalities are joining forces for the Connective Cities “Heat in the City” Deep Dive. Together they are analysing the impacts of heatwaves and how heat islands form in their cities, and they are developing solutions tailored to local conditions. The cities involved are Lüdenscheid and Heidelberg (Germany), Aswan (Egypt), Nairobi and Mombasa (Kenya), and Lviv (Ukraine).

At a meeting in Nairobi in March 2024 the delegates undertook detailed work to identify the challenges their cities face and started developing a strategy to manage them. By the end of 2024 they aim to implement pilot projects which can be scaled up at a later date. At a third in-person workshop in Heidelberg from 3 to 6 June 2024 they expanded on their pilot projects and drafted action plans for implementing the projects.

This documentation presents the results to date in detail.

Solar pumps, e-mobility, and climate-friendly street lighting in Sub-Saharan Africa

Posted on by erik

The workshop is part of a working group for Renewable Energy Applications for Cities convened by Connective Cities in collaboration with the Romanian development agency RoAid.

Apart from the municipal experts and the Connective Cities team, the conference was graced by the attendance of Daniella Dobre (RoAid), Massimiliano Pedretti (Delegation of the European Union to Tanzania), and Dr. Tobias Godau (GIZ ProWaS – Water Security and Climate Resilience for Urban Areas in Tanzania.

The conference was a follow-up event of the kick-off workshop in Nairobi in 2023, focusing on the topic of Street Lighting and E-Mobility applications in the urban context.

Participants

The participant experts represented the cities of Nairobi, Kisumu and County of Baringo (Kenya), City of Kasungu (Malawi), Gulu city (Uganda), City of Dar es Salaam, City of Mwanza and City of Tanga (Tanzania). The Working Group is accompanied by the international representatives from the cities of Gersthofen (Germany), Slatina and Alba Luluia (both Romania).

Participating institutions were:

  • Malawi Local Government Association (MALGA)
  • Regional Administration and Local Government Tanzania (PO-RALG)
  • The City Climate Gap Fund (through the project support office of the Global Covenant of Mayors)
  • The African Development Bank (through the Renewable Energy and Energy Efficiency Department)

Ideas presented:

All ten cities presented their projects and received advice. All ten cities are familiar with the prerequisites for funding and have completed 70% of these requirements.

Kisumu, Kenya:

Improving electric mobility and street lighting in the city of Kisumu. Piloting a PPP model for the deployment of charging infrastructure for 2- and 3-wheel motorcycles.

Baringo, Kenya:

Solarization of a water pump that pumps water from Lake Baringo to a treatment plant in Kabernet town.

Gulu, Uganda:

Solarization of the main street of Gulu City.

Mwanza, Tanzania:

Solar Project on Ijinga Island generated from solar panels to operate water pumps that push water to a treatment tank. Fundraising stage, feasibility analysis completed already.

Nairobi: Energy efficiency and Solarization of markets. Target pilot projects: City Market, City Park Market, Kangundo Road Market and Gikomba Market. Energy audits for these sites have been carried out.

Dar es Salaam: Solar powered street lighting along market street incorporating solar power radio for the market and charging stations for three wheelers.

Tanga: The cites faces an ever-growing landfill. The city intends to undertake a waste to energy project. To begin, the city therefore aims to undertake waste value chain analysis. This will highlight the waste characteristics and the attendant calorific values.

Kasungu: The City of Kasungu presented a double challenge of deforestation due to the heavy usage of biofuels (firewood and charcoal) and the high cost of power for lighting the streets compounded by lack of such streetlights in many areas. The city therefore prioritizes for the project to prepare a solution for solar street lighting still integrated with the main grid for back-up.

Malawi Local Government Association (MALGA): The proposed project focuses on installing solar-powered streetlights to improve lighting in selected municipalities and cities in Malawi. This initiative aims to enhance the local business environment, improve security, and contribute to local economic development.

Targeted Municipalities: Kasungu, Karonga, Luchenza, Mangochi.
Targeted Cities: Zomba City, another city to be determined.

Next Steps of the Working Group

In the journey to support the cities to develop solutions to their challenges, Connective Cities and RoAid plan to continue their support via:

  • Insight sessions and webinars: present emerging knowledge in short learning sessions.
  • Best practices: Publishing of innovative solutions of the collaborating cities.
  • Conferences / Workshops: to bring the city experts together to scale up peer to peer and associated learning.
  • Expert missions: will be availed to city experts with clear cases and inputs for experiential learning and exchange. This will include virtual formats where cities are connected according to relevance of needs.

Bonn benefits in the long term from expert exchange on SDG monitoring

Posted on by erik

The city of Bonn is considered a pioneer in reporting on the local implementation of the United Nations’ 2030 Agenda. In 2022, it presented its second voluntary implementation report – a Voluntary Local Review (VLR) – to the United Nations. A significant milestone in this journey was a dialogue event held in April 2021, which the city organized jointly with Connective Cities.

Growing attention for Voluntary Local Reviews

Bonn embarked early on the implementation of the Sustainable Development Goals (SDGs) adopted by the United Nations in 2015. It was among the first of approximately 40 cities worldwide to submit a VLR. Following the publication of its first VLR in 2020, there was a desire to further advance its work through international exchange and to share its experiences with others.

Strengthening Risk-Informed Urban Development in Sub-Saharan Africa

Posted on by erik

SADC Peer-to-Peer Learning Platform for Integrating Disaster Risk Management into Urban Planning and Development

The race against time to determine resilience-driven solutions to highly complex and existential urban disaster risk challenges is increasingly necessary more so in Africa. Projections point to the fact that by 2050, 90% of the global urbanization will be experienced in Africa and Asia. Despite Africa’s low contributions to Greenhouse Gas (GHG) emissions, the continent remains the most vulnerable to hazards and risk drivers like such as, but not limited to, climate change and (climate) variability. Evidently, Africa’s cities face exponential growth, unplanned urbanization trends and unfolding vulnerabilities threatening thus, to undo urban development gains. By 2050, most of the countries in the region will have made an urban transition, meaning that more than 50% of their population will live in urban areas, which are in turn, the cornerstone of Africa’s socio-economic development (IFRI 2022). As hubs of infrastructure, services, trade and people, cities are faced with one of the major urban threats in Sub-Saharan Africa (SSA), namely floods, subsequently challenging the continent’s socio-economic development ambitions. Urbanization is arguably an inevitable, unstoppable yet positive trend which nevertheless has the potential to greatly increase risk.

To incorporate integrated Disaster Risk Management (DRM) and climate change adaptation measures into multilateral and bilateral development cooperation programs – within and across all sectors -, Connective Cities (CC) and the Resilience Initiative Africa (RIA) have called the joint initiative on risk-informed urban development (RIUD) to enable peer to peer exchanges through a hybrid modular learning processes (LP). The LP focuses on strengthening risk-informed urban development by creating innovative solutions for flood risk management in urban systems situated in Sub-Sahara Africa with a focus in the Southern African Development Community (SADC) Region.

The LP enables the use of an agile, barrier-reduced learning and exchange platform for RIUD, which is used by regional, national, and local governmental and non-governmental actors. The modular and systemic approach of the LP for RIUD includes areas related to “Sustainable Urban Development” and “Good governance” facilitating the formation of new partnerships across vertical and horizontal scales for urban/regional resilience. Through the differentiated yet complementary political counterparts, between CC and RIA, the GIZ is able to ensure scalability and wide-spread transfer and communication of the results (i.e. RIUD SADC Publication).

To enhance resilience in southern African cities, CC and RIA developed a series of hybrid modular LPs (Live Events and virtual Insight Sessions) which focus on peer to peer exchange on integrated flood risk management in SADC as part of Sub-Sahara Africa.

The kick-off event in Windhoek, Namibia took place in April 2023 and marked the first round of the LEP by creating feedback loops to inform the development of context-specific, gender-equitable and climate-change-sensitive solution options directed at tackling urban flood risk challenges in both structural and non-structural terms. During the kick-off event, the peer-to-peer exchange was guided by initial thematic areas i.e: 1) Understanding and managing flood risk drivers, 2) Green infrastructure and nature-based approaches for risk-informed solutions, and 3) Risk communication flows and good governance.

Local Economic Development Forum in Tbilisi

Posted on by erik

Tbilisi, June 7th – Connective Cities Southeast Europe convened a parallel session during the Local Economic Development (LED) Forum in Tbilisi, focusing on “Renewable Energy Options at the Municipal Level.” This session provided a platform for mayors from Georgian municipalities, including Senaki, Eredvi, and Khoni, to exchange insights, challenges, and innovative approaches in advancing renewable energy initiatives within their jurisdictions. Furthermore, Dr. Irakli Samkharadze, Energy Advisor of Omnia, provided insights into the European Green Deal and its implications for municipalities, enriching the discussion with a broader perspective on sustainable energy transitions.

The Mayor of Senaki Municipality shared notable advancements, including the integration of renewable energy sources into municipal buildings and the installation of solar panels across various locations to raise awareness and support action plans aligned with the Covenant of Mayors.

Showcasing the Amman Urban Observatory

Posted on by erik

The insight session on “Showcasing the Amman Urban Observatory” was held on 24 April 2024, delivered by Mr. Akram Khreisat from the Greater Amman Municipality. The session was organized by Connective Cities and presented to the global community of urban practitioners, as part of the Connective Cities network. Among the participants were urban practitioners, local and national government actors, academic researchers, non-governmental organizations, and local community members.

Mr. Akram Khreisat, director of the Amman Urban Observatory, introduced the participants into the working mechanisms and the fields of action of the Amman Urban Observatory and its role in tackling planning challenges in the capital city of Jordan.

The Amman Urban Observatory generates ‘urban indicators’ to monitor various aspects of the city that are important for urban development. Based on real-time monitoring of these urban indicators, planning processes in urban development are improved, as planners and developers are empowered to make informed decisions. In doing so, the observatory works together with ministries, government departments, national organizations, NGOs and companies from the private sector. The observatory works together with over 40 partners and stakeholders. Such urban indicators include vital characteristics for measuring sustainable urban development such as unemployment rate, land cover or the percentage of people living in poverty.

The Amman Urban Observatory has proved itself to be an effective tool for strategic and urban planning. Mr. Akram Khreisat described the observatory as not being a tool, but as a “process to achieve the Sustainable Development Goals”. In the case of the Amman Urban Observatory, the indicators created focus on the thematic areas of the following SDGs: Good Health and Well-Being (3); Affordable and Clean Energy (7); Industry, Innovation and Infrastructure (9); Sustainable Cities and Communities (11); Climate Action (13) and Partnerships for the Goals (17).  

After the presentation by Dr. Akram Khreisat, the attendees asked questions about the Amman Urban Observatory. When asked about the challenges and difficulties the observatory faces, he elaborated on the large influx of refugees that Amman receives and the associated challenges for the measurement of urban indicators. As the city recently receives many refugees, indicators need a certain flexibility to account for the inconstant change of inhabitant numbers. Furthermore, Mr. Khreisat was asked whether the observatory uses the gathered data for spatial analysis or 3D cadaster purposes. In answering this, he elaborates that they work together with the city’s GIS Department in order to deliver scenario plans for spatial growth.

The Connective Cities Network intends to create a working group to identify different best practices for the observation of urban parameters. Furthermore, interested cities are intended to be assisted through the development of templates that can be used to implement in a similar process to the one in Amman. Any city representatives interested in joining the working group are very welcome to contact Dr. Muna Shalan (muna.shalan@giz.de) and Mr. Jimmy Yoedsel (jimmy.yoedsel@giz.de) for further information and the possibility to take part.

Connective Cities would like to thank Dr. Akram Khreisat and all the participants for the presentation of the Amman Urban Observatory and for the fruitful exchange and discussion.

Dar es Salaam Metropolitan Development Project (DMDP) – Phase 1

Posted on by erik

The Dar es Salaam Metropolitan Development Project (DMDP) aims to improve connectivity and mobility within the city while reducing flooding through structural and non-structural measures. As part of the project, 67 kilometres of rainwater channels were built. The focus was on training local government experts, solid waste management and urban greening initiatives.

However, the DMDP also became aware of various issues and challenges that the city faces in drainage management. These include the effects of climate change, such as flooding, storms, heat, drought and sea level rise, as well as an inadequate stormwater drainage system due to a lack of suitable corridors and space for retention basins. Unrestricted access to stormwater drains has led to misuse for sewage and waste disposal.

The effects of rapid urbanisation also had to be taken into account: Around 70 per cent of Dar es Salaam’s population lives in unplanned settlements, mostly in very exposed locations. Community involvement is crucial here: it can help build trust, ensure sustainability and promote ownership of flooding control projects. Cooperation and coordination between different stakeholders, including authorities, municipalities and other organisations involved in the project, as well as effective communication and coordination are essential.

Six municipalities join forces to combat increasing heat in cities

Posted on by erik

From 3 to 6 June 2024, the group came together in Heidelberg as part of the “Connective Cities Deep Dive” to substantiate their pilot projects and learn from the experiences of other cities.

Although the six cities have to adapt to increasing heat in different ways, they have two principles in common, as became clear during their exchange in Heidelberg. If you want to do something strategically and in the long term to combat heat in cities, you need a plan. This is just as true for Aswan in Egypt, where temperatures can reach 50 degrees Celsius in summer, as it is for Lüdenscheid, which is located in the cooler, densely wooded Sauerland region of Germany. They also strongly believe in the approach of initially testing innovative heat solutions in small pilot projects before implementing them on a larger scale.

There are many ways for cities to reduce the negative heat effects on the population: creating more green spaces, planting shade-providing trees, greening building facades, creating cooling corridors, for example through watercourses, raising public awareness and much more. To do this, it is first important to know where the heat builds up in a city.
