The second day of the workshop started with the introduction of the case studies to the delegates. The main aim of introducing and taking up case studies as a workshop exercise was to make to delegates understand the importance of local flood mitigation measures and related water issues.  The additional aim was to make the delegates understand the other benefits of flood mitigation measures such as enhanced livability, ecosystems services such as urban agriculture, reduction in temperature, etc,. The mode of learning on first day was mainly through listening to the experts and practitioners, whereas on Day 2 the delegates were learning by  making use of the knowledge they had gained on Day 1  through the case studies.  Upon completing the exercise the delegates were expected to understand the following,

  • How can we ensure that performance criteria are met after implementation of measures?
  • What additional functions can be integrated to enhance the functionality of design?
  • How can we ensure the performance in Long, medium and Short term?
  • How can the design be adapted to future conditions (flexibility)?

The case studies were introduced by Williem Veerbeek and Mohanasundar Radhakrishnan. Case Study 1 was a new housing complex development proposal in An Hoa Ward in Ninh Kieu district of Can Tho. The participants were provided with  information such as the current proposals and were asked to assess the threats that could be encountered during the implementation of the proposed plan. The second case study was about the development of Bun Xan marsh land into a water body as recommended by the drainage master plan for Can Tho. Apart from providing essential information to the delegates about the case study 2 additional information about the Xan Thoi lake development project was also provided so as to impart the knowledge gained during the execution of the project. The aim was to learn from the previous experience to increase the efficiency of positive measures and not to repeat the mistakes. Owing to the considerable number of delegates of the workshop hailing from Can Tho as well as the case studies being real projects that are at the advanced stages of planning and approval by the concerned city departments, they aroused the curiosity of the delegates and the interest level was very high among the delegates. Case study 1 in An Hoa ward, in particular lead to a lot of discussions and debates. Hence it was to  decided to focus more on this case.

Perceptions on development projects vary with respect to the nature of stake holder.  Ms.Outi Annala from AssistAsia talked about the importance of developing business cases. She presented few cases where the industry partners collaborated with local stakeholders towards attaining cleaner and greener production measures.

The delegates worked on the threats, perceptions and possible measures till noon. After lunch the delegates were taken to the case study area and saw themselves how the actual conditions were at the site in An Hoa. The delegates were very inquisitive and were seen interacting and talking to the inhabitants of the area.

They were also taken to the Xan Thoi lake as beautification work of the lake and the canal leading to was completed recently. The aspirations and expectations of the inhabitants before and after the realisation of the beautification project were explained to them. Though the lake has got firm embankments, functioning flap gates and lined canals, the water quality in the lake has not improved considerably. The lake cannot function as a detention pond  if rainfall and high tides occur at the same time as the drainage outfalls are lower then then the high tide level.

The delegates were asked to revisit the threats, perceptions and possible measures they had arrived at before the site visit and rework on that based on their understanding of what they experienced during their site visit.
