Goals of the task
Task 6.2 applies the RP Simulator, developed in Task 5.4, to simulate the scenarios which have been defined in Task 6.1. Results of the scenario simulation highlight to the local actors the effects of planning measures suggested and possibly illustrate the benefits of a trans-sectoral approach. Furthermore, the scenarios will provide a better understanding of the impacts of future developments (e.g. demographic development, expansion of supply and disposal infrastructures) and will thus further the trans-sectoral consideration of the urban infrastructure and support sustainable management of resources.
Work done to achieve the goals
Substantial preparatory work in the implementation of novel modelling and simulation concepts (see Task 5.4), which will allow rapid model setup once the required data are available, and in setting up draft models of the case cities Da Nang, Kigali and, to a lesser intent, Frankfurt, has been done. As a result, an integrated model of the water, wastewater, energy and waste system of Da Nang was set up (Fig. 61) and preliminary results of material and energy flows at city district level are available for the base case. Therefore, it is expected that scenario simulation can be carried out in good time.
Another activity that has been carried out includes the preparation of a preliminary list of social, environmental and economic criteria for the evaluation of sectoral and trans-sectoral planning alternatives in close cooperation with TUB.
The participation in a working trip to Da Nang in March 2015 provided with many opportunities, for various individual meetings with institutions related to the water, wastewater and waste sectors and a meeting with University of Technology Da Nang. Also a trans-sectoral working group in Da Nang has been established to support the RP activities. These activities also served to discuss and refine the modelling approaches implemented for Da Nang. In a similar way, the RP Biannual meeting in Frankfurt in October 2015 provided the opportunity to discuss and to refine modelling concepts with representatives from Da Nang, Kigali and Assiut.
In a smaller round table and with the sector experts and scenario working group, information and requirements for the trans-sectoral modelling of the supply and disposal infrastructures of Da Nang have also been discussed
As a first test of transferability of the RP modelling concepts, their application to the water sector to the city of Cali/ Colombia and their connection to the principles of “Cleaner Production” form part of the graduation work of a student from Colombia.
