Flash flood that hit the West Flood Canal (Kanal Banjir Barat), which is the downstream of Garang River (Kali Garang) in 1990, still left some terrible memory for the locals. During the event, many of them witnessed how their neighbors and even families fell victims, lost their lives and possessions. According to the incident record, the flash flood in that year inundated more than 100 houses and claimed 47 lives. Material loss was estimated to be at 8.5 billion rupiahs. The flood can be considered as one of the worst that ever occurred in Semarang City.
Flood resilience within the Garang Watershed in Central Java has at the least involved two main regions which are Semarang Regency and Semarang City. Semarang Regency, which is located in the upstream area, is ecologically important in terms of flood management that could affect the mid- and downstream area. Therefore, it is important to maintain the quality of the ecosystem and its services that contribute to flood prevention such as the storm water management.
According to Article 6 of the the United Nations Framework Convention on Climate Change (UNFCCC), countries are supposed to ensure awareness, education and capacity building to tackle climate change with the developed countries while also support these efforts in the developing countries. It challenges the prevailing paradigm under which nearly a billion dollars had been invested in supporting capacity building.
The World Bank report estimated around 140 million across Asia and Africa, with 40 million in South Asia will be displaced and become climate migrants due to the adverse impacts of climate change. Of them, around 10 million or more are likely to end up in Dhaka. How could Bangladesh cope up with these upcoming challenges?
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?
