According to BNPB (Indonesian National Board for Disaster Management), more than 93% of disasters in Indonesia are hydrometeorological disasters. Out of 2,341 disaster events, 787 were caused by flooding. Some of the affected areas share the same watershed, which has proved to share trans-boundary waters that are facing increasing demands for basin development collaboration.
Floods in 2017 that affected nearly 40 million people across India, Nepal and Bangladesh were strong reminder that disasters and their impacts are often not contained by any national or other jurisdictional boundaries. This results place strong emphasis on transboundary governance systems. The question is what can we do to manage transboundary action better?
Semarang deals with various physical challenges due to its geography as a coastal city; it is known specifically for its frequent floods. There are 21 rivers located in Semarang, creating a high risk of flooding. In response to that, Semarang City Government has carried out several actions to reduce flood risk through the construction of Jatibarang reservoir, normalization of Semarang Flood Canal, and also improvement of the drainage system.
The sun shone brightly as if welcoming us to what is famously called ‘shrimp city’: Cirebon. Located on the northern coast of West-Java, the sea has caused the city’s temperatures to be quite high. Cirebon is said to be one of the country’s most drought-prone cities. In 2015, nearly 14,000 ha rice fields experienced drought. However, when it starts to rain some parts of the city are also prone to flooding. Therefore, environmentally conscious planning should be used to overcome these challenges.
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.
