Conference paper (peer-reviewed)abstract
- The old city of Fez, Morocco, classified as Heritage of Humankind by the UNESCO, is subject to an integrated rehabilitation plan running over 15 years. The plan aims at restoring and preserving the economy, cultural value, and social heritage of the old city. The study follows a system dynamics approach to describe and analyze the rehabilitation plan in order to identify the strengths and defects of the plan. This study shows that while the plan is giving relatively satisfying results over the short and medium terms, it is unlikely to attain long term sustainability.

The coming water shortage in the Jordan River Basin - Finding objectivity in a subjective problem
- 2002
-
In: Proceeding of the 20th International Conference of the System Dynamics Society. ; , s. 78-78
-
Conference paper (peer-reviewed)abstract
- Water distribution and availability in the Jordan region were studied. Self-sufficiency in water availability within the region is determined by the minimum amount of water used per person that is renewable. The objectives of the study were to identify the causes of water shortages and alternative use of water to prolong future supplies. According to our analysis, Israel and Jordan will overutilise their water source by a factor of 2 and Palestine by a factor of 1, by the year 2030. Water recycling has a potential in all the countries. The agricultural sector makes up the bulk of the water use (73-85%). Different water-saving techniques and alternative crop production can drastically reduce water use. Diverting away from agriculture and alternatively developing the industry sector would alleviate the immediate water shortages but will make the region dependent on the global grain market.

The Rubber Industry and Extended Producers' Responsibility Framework: Opportunities and Threats for Swedish Rubber Manufacturers
- 2002
-
In: Proceeding of the 20th International Conference of the System Dynamics Society. ; , s. 88-89
-
Conference paper (peer-reviewed)abstract
- An array of sustainable ways either to reduce the amount of waste rubber generated or for the re-utilisation of waste rubber products as different means of resources at the end of their service lives are provided and briefly evaluated from economic, social and environmental perspectives. Potential measures which the Swedish rubber industry and its major stakeholders can implement (within the context of extended producer’s responsibility framework) to increase source reduction, reuse, material recycling, and energy recovery from waste rubber are examined. Based on the concept of system dynamics, the links between different issues, possible problems arising from them and the solutions, and their relation to the sustainable waste rubber management system are analysed by understanding the cause and effect relationship between important parameters. A model is developed using Stella 5.1.1u to help the decision makers to evaluate different scenarios in Swedish waste rubber management.
