In the past week, there have been devastating floods in Houston, Texas in the United States of America as well as in Nepal, India and Bangladesh, not to mention China as well.
Although these events occurred in very different parts of the planet and each had somewhat unique causes and circumstances, nevertheless, their severity can now credibly be linked to human induced climate change that has already raised global mean atmospheric temperatures above one degree Centigrade since pre-industrial times.
On 14 June 2017, ACCCRN had the opportunity to visit the urban planning exhibition at the Department of Urban and Regional Planning at Diponegoro University. In this semester, the third year undergraduate students are focusing on designing Banjir Kanal Timur (east flood canal) as sustainable waterfront settlement based on the problems findings in the area. At a length of 14.5 km and with an average width of 35 meters, the river crosses seven districts in the city. As part of their urban design studio course, the students are divided into groups to focus on eight segments of the river.
According to a survey of some parts of the Banjir Kanal Timur (East Flood Canal) area in Semarang City, there are several findings that are considered to be problems. The situation has become difficult because of the rapid urbanization that has the impact of increasing the needs for infrastructure because of the pressure of increasing population and its domino effect on the environment. Some of the visible problems in the area include slums and squatters and the lack of open space.
The majority of the city of Da Nang is surrounded by water and it is susceptible to regular flooding and tropical typhoons. With a population of roughly one million and a growing economy, this city has a lot to lose when water rises. To meet this challenge, Da Nang became part of the Asian Cities Climate Change Resilience Network (ACCCRN) in 2009, and in the following year undertook a project that would change flood risk reduction within the city, the region, and possibly the whole country.

Coastal flood hazards are diverse and highly unpredictable. In order to develop an appropriate risk management response, it is essential to understand these hazards and their potential impacts. The following steps outline the building blocks for formulating a coastal flood risk management plan, which can be tailored according to the context of a country with its own particular hazards, stage of development, socio-cultural characteristics and institutional structure.
