Integrative Urban and Environmental Planning Framework - Adaptation to Global Climate Change (WP Urban Flooding and WP Urban Energy)

Motivation

Because of its topographic location, Vietnam is extremely endangered by climate change, like international comparison studies show. Especially the metropolises and economic centres of the country - Hanoi and Ho Chi Minh City (HCMC) - are affected. Within its fund "Sustainable Development of the Megacities of Tomorrow" the Federal Ministry of Education and Research (BMBF) granted the project "Megacity Research TP. Ho Chi Minh" with a duration of five years in July 2008 which has been coordinated by the Brandenburg University of Technology Cottbus. The Leibniz Institute of Ecological and Regional Development (IOER) participates in the project by working on two work packages (Urban Flooding and Urban Energy).

At the moment the metropolitan area of HCMC suffers from flooding with novel forms of inundation. The IOER will, in collaboration with the Free University of Berlin (Chair of Remote Sensing and Geoinformatics), identify areas of conflict during different inundation situations for the study area of HCMC and derive danger maps.

With about eight million inhabitants and an annual economic growth of more than 10%, as well as booming construction activities, HCMC alone claims a quarter of the entire energy consumption in Vietnam. Therefore the topic energy is of major importance to a highly dynamic megacity like HCMC.

Objective

The aim of the IOER contribution to the subtask "Urban Flooding" is to build a Geodatabase for flood management and to create flood hazard maps for HCMC. In the subtask "Urban Energy", together with the Vietnamese partners, the spatial distribution of the energy consumption in the residential sector of HCMC is to be determined and analysed as well as the energy production and the structure of the energy sources.

Questions

  1. How can flood hazards in HCMC be exactly spatially localized?
  2. Which urban structure types can be identified for HCMC regarding a sufficiently exact modelling of the energy consumption in the residential sector?
  3. With which accuracy and confidence can energy relevant data be collected in HCMC?
  4. Which energy relevant development statements and recommendations for actions can be derived for the improvement of the energy and climate efficiency of residential areas of HCMC considering the local context?

Methodology

The applied methods encompass mainly geodata processing, the analysis of radar data, the mapping of urban structure types, the classification of buildings, energy modelling and scenario techniques.
