A Conceptual Framework for Flood Impact Mitigation Through Transboundary River Management

Abstract

Successful mitigation of flood risk requires an integrated, basin-wide approach. This is particularly important in transboundary river basins, where the actions of multiple stakeholders must be coordinated. The Ciliwung River, Indonesia, presents an example of a complex urban basin that crosses multiple administrative borders. The increasing frequency and severity of floods in the downstream capital city of Jakarta has highlighted the need for better river governance arrangements. However, it is unclear what form these arrangements should take. This paper aims to develop a conceptual framework that identifies the key concepts relevant to flood management and governance in transboundary river basins and how they relate to the situation in the Ciliwung. Key concepts were drawn from a review of the literature conducted using online databases and search engines. The framework firstly outlines the flood hazard itself in terms of drivers and impacts. It then goes on to establish the associated governance arrangements and identifies any interdependencies. The framework highlights multiple interrelated drivers of flood risk, both human and physical. There is also a range of governance issues related to capacities, coordination of institutions, and fragmentation of plans and policies. Due to flood risk and river management complexities, this conceptual framework provides much-needed clarity to develop improved management arrangements in the Ciliwung River Basin. It also sets a framework to facilitate future research on transboundary management in relation to flood risk in other urban and peri-urban river basins.

The historical perspective of flood occurrences in the Shire River basin, Malawi

“…Flooding and population vulnerability have increased dramatically in recent decades as a result of several factors, including urbanization, climate change, land-use pressures, and severe weather variability, all of which have increased ood intensity and frequency, posing a threat to many regions' development strategies (Dinh, Balica, Popescu & Jonoski, 2012;Jonkman & Dawson, 2012;Twar, 2016). Historical changes in ood susceptibility are complex and dynamic, in uenced by economic, social, demographic, cultural, institutional, and governance factors (Clegg, Haigh, Amaratunga, Karunarathna, Rahayu & Septiadi, 2021). Flood events that have occurred in Asia accounted for 41% of the world, comparatively followed by 23% in America, 17% in Africa, 14% in Europe, and 4% in Oceania (Perera, et al, 2019).…”
