Stewardship Partnerships for Sustainable Natural Resources Management: Regional Exchange for a Just Transition in Economic Zones
As part of their national development goals, many countries are expanding production zones – creating economic hubs that pose both environmental risks and opportunities for large-scale resource efficiency. But how can industrial growth happen without degrading ecosystems and vital natural resources? And how can this transition be socially just, leaving no one behind?
Better together – Partnerships for Collaborative Action on Sustainable Resource Management in Economic Zones

During a three-day regional learning and exchange event, more than 50 participants from different sectors (public, private, civil society) from NatuReS partner countries Ethiopia, South Africa, Zambia and Tanzania came together in Dar es Salaam to shed light on these pressing questions. The consensus was clear. No actor can solve this issue alone. It needs partnerships between the public and private sectors as well as civil society to find shared solutions. Thus, it was no surprise that the event was opened with a strong call for action, collaboration, and innovation.
Balancing Industrial Growth with Environmental Stewardship in Tanzania
Representing the Ministry of Industry and Trade of Tanzania, Mr Aristides Mbwasi, Director of Investment at the Tanzania Export Processing Zone Authority (EPZA) spoke about the importance of balancing industrial development with environmental stewardship. He advocated for social-ecological and transformative measures and integrative solutions that promote economic growth while protecting vital natural resources. Mr Mbwasi stressed the role of sharing knowledge and best practises in order to bridge the gap between industrialization and sustainability to advance a Just Transition.
In his opening remarks, Mr Elibariki Mmassy, Basin Director of the Wami/Ruvu Basin Water Board (WRBWB) in Tanzania, highlighted the urgency of integrated water management in the face of pollution, overuse, and climate change. He emphasized that water security is not only a technical issue – it is also a matter of social justice. He called for transformative solutions to wastewater management and pollution control, highlighting opportunities for private sector engagement.


Water Security for Economic Zones: Lessons from Stewardship Multi-Stakeholder Partnerships Across the Region
After setting the scene for the following days full of discussion and learning, participants had the chance to look beyond their own turf and explore how stewardship multi-stakeholder partnerships are identifying and collaboratively addressing shared natural resources risk. Besides discussing technical solutions such as rainwater harvesting or nature-based solutions, the panellists pointed out that to overcome these challenges, private sector, government and civil society have to work hand in hand to enhance water security and sustainability. To this end, global frameworks such as the International Framework for Eco-Industrial Parks (EIPs) can function as a strategic lever to link commercial success with socio-ecological responsibility.

Making a Business Case for Collaborative Water Stewardship
In a lively fishbowl discussion, participants discussed what makes compelling business cases for collaborative action between all sectors, identifying key drivers, enablers and challenges. Key takeaways include:
- Private sector must shift from profit-only models to sustainability-driven strategies, embracing compliance and innovation.
- Public sector plays a critical role as enabler and regulator, translating policy into impactful action.
- Financing mechanisms like impact investment or investment platforms can scale up solutions, with success measured by both economic returns and socio-ecological impact.



From Dialogue to Action – The Partnership for Sustainable Economic Zones within Benjamin William Mkapa Special Economic Zone (BWM-SEZ)
The second day of the event was packed full of action with a field visit to the premises of the Tanzania Export Processing Zone Authority (EPZA) located within the Benjamin William Mkapa Special Economic Zone (BWM-SEZ). This gave participants the opportunity to see how the Partnership for Sustainable Economic Zones, which is supported by NatuReS, jointly drives activities for a socio-ecological transformation on the ground. The visit also presented the perfect opportunity for the official signing of the new partnership action plan.


Initially formed in 2018, the Partnership for Sustainable Economic Zones has achieved great results in its efforts to enhance water security within the special economic zone.
Notable achievements and activities include:
- Establishing wastewater management guidelines for the zone
- Upgrading the sewage pumping station
- Introducing solid waste management systems for the zone
- Enhancing water use efficiency through the expansion of the Tooku Garments wastewater treatment plant and enhancement of water use efficiency
In addition to gaining insights into the collaborative strategies and actions implemented by the partnership, participants had the opportunity to visit the wastewater treatment plant of Tooku Garments, one of the largest tenants in the Benjamin William Mkapa Special Economic Zone (BWM-SEZ). The visit provided valuable learnings on the practical application of wastewater management solutions and highlighted the importance of sustainable industrial practices in that regard.


Addressing Water Resource Governance Challenges in Tanzania and Beyond
On the last day of the regional exchange event, participants travelled all the way to Morogoro to visit the Mindu Dam which is part of the Wami/Ruvu basin that provides the water resources for millions of people in the region.
Representatives from the Wami/Ruvu Basin Water Board (WRBWB) shared the challenges they face, such as increased water usage and abstraction due to rapid population growth and industrialization, particularly in the Dar es Salaam and Dodoma areas. Pollution from upstream sources also poses a significant threat to water quality. The Board’s role is to ensure the sustainable availability of water resources to support both community well-being and national economic growth.


Following the dam visit, participants were hosted at the Wami/Ruvu Basin Water Board (WRBWB) headquarters, where they were introduced to the journey undertaken by the WRBWB, with support from NatuReS, to improve water resource management and governance in Tanzania. This included the evolution of a water permitting process, from initial concepts to the launch of the national Water Use Management Information System (WUMIS). The WUMIS system can be used both for water abstraction and wastewater discharge permits by various sectors. Participants also learned how WUMIS is currently transforming from a rather complicated, paper-based system into a digitized process that streamlines permit applications, payments, and management, thereby significantly enhancing water governance and improving water resource management in Tanzania.

Additionally, Rosemary Rwebugisa, Assistant Acting Director in the Ministry of Water, emphasized that, alongside improvements in the water governance system, it is crucial to actively involve local communities in water source protection activities. This holistic approach ensures the long-term sustainability of water resources and fosters greater community ownership and responsibility for water conservation.
The insights gained from the water governance journey in Tanzania generated significant interest among participants from Ethiopia, Zambia, and South Africa, offering valuable inspiration to explore similar pathways for enhancing water governance in their own contexts.

Looking Ahead: Building a Just and Resilient Future through Partnerships
The regional exchange reaffirmed that water stewardship is a cornerstone of a socio-ecological transformation, particularly within the context of economic zones and industrial development. Stewardship multi-stakeholder partnerships have proven to be powerful drivers, bringing together actors from across sectors to foster transparency, inclusivity, and shared responsibility on the path to a Just Transition.
Through the power of knowledge exchange, supportive policies, and the joint implementation of innovative solutions, partner countries are advancing toward a future where healthy ecosystems, resilient communities, and thriving sustainable industries are not distant goals – but shared, lived realities.
