Designing SIA - Retrofitting


Many existing industrial areas which have been established years ago were planned and implemented without any sustainability considerations. Some of them developed organically without a proper planning at all. Old industrial areas are often too densely constructed without an adequate infrastructure and sufficient open green spaces. They have no proper or only an inappropriate sewage and waste collection system, and no facilities for wastewater treatment. The electricity lines are too weak to cater for more, and more workshops and production sites and public transport in the area are insufficient for a growing number of workers and employees. The results are environmental pollution, bad working and living conditions and growing conflicts with neighbouring communities.

GIZ expertise

Experiences of GIZ for retrofitting industrial areas or reactivating former industrial land are given in the following documents:

  • Sustainable Management of industrial areas (SMIA, GedZI, ProCAIS)

    Sustainable Management of Industrial Areas (SMIA, GedZI (French), ProCAIS (Spanish)) is an innovative approach to systematically improve the sustainable management of industrial areas (IA) promoting and supporting the development of resilient Industrial Areas. Industrial areas applying SMIA aim at fostering Green and Inclusive Economy

    • by increasing competitiveness through efficient use of both, non-renewable and renewable resources;

    • by generating green and decent jobs;

    • by minimising environmental and climate impact, as well as risks; and

    • by continuously improving the overall efficiency of management and cooperation structures.

    Thus, SMIA contributes to the SDG goal 9 “Industry, Innovation and Infrastructure” and to climate-resilient, sustainable development.

    The original method applied in 2006 by e-Parc, France, UNEP-IE Paris, and PREMAnet-GIZ drew on the combination of three well established and widely used and cost-effective methods and tools, i.e. PREMA© (, APELL and Eco-mapping.

    Since then, the original concept has been profoundly modified, enlarged and enhanced during applications in Tunisia (ReCapZI, CCP-RAC), Indonesia (GIZ-EU), Ghana (GIZ-PREMAnet-CAD), Peru (GIZ) and Mexico (GIZ). SMIA 4.0 version integrates more comprehensively climate change and biodiversity aspects, thus enhancing the resilience perspective (Sustainable Management of Resilient Industrial Areas SMaresIA).

    A French language version (GedZI – Gestion durable des Zones Industrielles) specifically considering the situation in Tunisa was developed by GIZ ReCapZI.

    A Spanish version (ProCAIS – Programa de Competitividad de Áreas Industriales a través de la Sustentabilidad) specifically consider the situation in Mexico was developed by GIZ PGAU II.

  • Sustainable planning and retrofitting of industrial parks in Tunisia

    During a workshop in December 2012, the most affected Ministries articulated the priorities concerning the planning, design and setting up of industrial parks in Tunisia. The top priorities identified were the establishment of a feasibility study before setting up an industrial park, the elaboration of a Site Master Plan for each industrial park (including existing ones), the elaboration of an exhaustive list of criteria for selecting a site for industrial parks, and the elaboration of propositions for a better management within industrial parks. The elaboration of a manual that helps policy makers and planning departments to develop a Site Master Plan as a strategic tool for each industrial park followed.

  • Wastewater management in industrial parks

    Common effluent collection and treatment systems in industrial parks are often either not existing, dysfunctional or not functioning properly in many developing countries. The causes are diverse and must be thoroughly examined from case to case.

    The tool includes case studies, best practice examples and management manuals elaborated by GIZ and KfW projects in various Asian countries.
