The Federal Emergency Management Agency provides guidelines for the management of open space created through property acquisition (buyouts); however, land use decisions are primarily left to local governments manifesting in a variety of uses. The purpose of this paper is to provide a land use assessment of buyout sites, to describe the changes in those uses that have occurred during a ten-year period from 1990 to 2000, and to offer an assessment of management approaches employed across these sites.

Using a mixed-methods approach consisting of a land use classification survey and a semi-structured questionnaire of floodplain managers, this study explores the land use trends at buyout sites, diverse approaches local governments take in managing the open spaces created through floodplain buyout programs, and the successes and challenges communities face in open space management.

Results indicate strong support from floodplain managers for property acquisition and several cases emerged where communities put their newly acquired public land to creative uses. However, the opportunity to leverage these properties for greater public values is largely being missed, primarily because of limited funding.

The analysis indicates strong support among floodplain managers for the buyout approach; however, additional resource-sharing and funding opportunities are needed to increase the utility of buyout properties.

By evaluating the long-term management strategies floodplain managers utilize on buyout sites, this study adds to an underrepresented area of scholarship and is of value to practitioners, government officials, and academics.

This study aims to support the development risk management strategies towards improving the resilience of assets located in the estuary and lower level of the Swan River, Western Australia. The study evaluated the key role of Federal/State policies in adaptation planning and the communication and interface between various stakeholders, including State/Local governments, construction professionals, property developers and landowners.

The study applied a mixed research approach through a questionnaire survey followed by an in-depth interview involving local construction experts. Collected data were analysed following the grounded theory methodology style of data analysis.

The findings revealed a convoluted understanding of communication networks and responsibility for owning the future risks between relevant stakeholders. As a result, a framework illustrating clear process and roles in mitigating risk and implementing adaptive asset management measures has been formulated and presented in this study.

Scientific evidence suggested that sea-level rise and increased frequency of major coastal flooding events are inevitable as early as 2100, and having a comprehensive risk management plan of assets to anticipate climate risks and to improve urban resilience is essential. The proposed framework is aimed at local stakeholders in improving current state of communication and adaptation planning as a pathway to develop a robust risk management strategy.

The purpose of this paper is to review the crucial elements of integrated river basin management (IRBM) and their legal frameworks which have to be considered in a comprehensive management approach. A wide range of decision support systems (DSS) have been developed for IRBM‐related fields during the last few decades. However, most of the developed systems are either not used in practice or are used by people other than those they were designed for. The paper also discusses whether DSS are useful for IRBM and presents the requirements which have to be considered in the development of IRBM‐DSS.

Beside literature research, a variety of requirement elicitation techniques such as interviews, buzz groups, questionnaire and prototype evaluation were employed. Feedback from roughly 200 experts representing different work fields and river basins in Central and Western Europe was collected.

Different legal frameworks of IRBM fields were analysed with a view to determining whether they can be applied in a comprehensive approach. Broad elicitations affirm that DSS can assist in various phases of planning and management processes. Some general requirements of DSS for IRBM can be identified which should be considered in DSS development. DSS can be described as socio‐technical instruments and “communication vehicles” because of their multiple roles in participation processes.

The paper illustrates different elicitation techniques used to specify what users require of DSS. Furthermore, it describes some essential requirements for DSS development such as the main added value, key functionalities and factors for successful implementation.

The described results are based on my own studies and elicitations which have been conducted in the course of the past two years.

Flood preparedness and response from the perspective of community engagement mechanisms have been studied in scholarly articles. However, the differences in flood mitigation may expose social and behavioural challenges to learn from. This study aimed to demonstrate how text mining can be applied in prioritising existing contexts in community-based and government flood mitigation and management strategies.

This investigation mined the semantics researchers ascribed to flood disasters and community responses from 2001 to 2022 peer-reviewed publications. Text mining was used to derive frequently used terms from over 15 publications in the Scopus database and Google Scholar search engine after an initial output of 268 peer-reviewed publications. The text-mining process applied the topic modelling analyses on the 15 publications using the R studio application.

Topic modelling applied through text mining clustered four (4) themes. The themes that emerged from the topic modelling process were building adaptation to flooding, climate change and resilient communities, urban infrastructure and community preparedness and research output for flood risk and community response. The themes were supported with geographical flood risk and community mitigation contexts from the USA, India and Nigeria to provide a broader perspective.

This study exposed the deficiency of “communication, teamwork, responsibility and lessons” as focal themes of flood disaster management and response research. The divergence in flood mitigation in developing nations as compared with developed nations can be bridged through improved government policies, technologies and community engagement.

The purpose of this paper is to identify the importance of floodplains in preserving biodiversity, and call attention to alternative ways of managing floodplains in relation to probable scenarios of climate change.

In total, 20 water bodies on the floodplain at Flisa along the River Glomma (Hedmark County, Eastern Norway) were investigated with regards to crustacean zooplankton and water beetle species richness.

Both on a national and regional scale, the species diversity in the investigated water bodies was high. A total of 57 crustacean plankton and 77 water beetle species were recorded. Of these, ten and eight were new records of zooplankton and water beetle species in Hedmark County, respectively. Seven recorded water beetle species were specified in the 2010 Norwegian Red List of Species. Further, the localities on the Flisa floodplain are relatively unique with regard to the composition of species compared to other investigated localities in Hedmark County.

Floodplains are intensively used and are considered as among the most threatened ecosystems in the world. More frequent and less predictable floods can be expected in the future due to climate change's influence. In some settings more frequent larger floods may work to re‐establish the connectivity, but larger floods might also result in demand for construction of more extensive flood mitigation measures.

The results from this case study underpin the high biodiversity of floodplains, an ecosystem infrequently examined in Norway. The results of this study are of importance regarding management and maintenance of ecosystem services (e.g. biodiversity and water retention) from floodplains.

The purpose of this paper is to re-frame planning decision-making to address risks of flooding and to increase community resilience. Rapid urbanisation, fragmented governance and recurrent flooding complicate resolution of DKI Jakarta’s chronic housing shortage. Failure to effectively implement planning decision-making processes poses potential human rights violations. Contemporary planning policy requires the relocation of households living in floodplains within 15 m of DKI Jakarta’s main watercourses, further constraining land availability and potentially requiring increased densification.

This paper presents a preliminary scoping study for a technologically enhanced participatory planning method, incorporating synthesis of existing information on urbanisation, governance and flood risk management in Jakarta.

Responsibility for flood risk management in DKI Jakarta is fragmented both within and across administrative boundaries. Decision-making is further complicated by: limited availability of land use data; uncertainty as to the delineated extent of watercourses, floodplains and flood modelling; unclear risk and liability for infrastructure investments; and technical literacy of both public and government participants.

This research provides information to facilitate consultation with government entities tasked with re-framing planning processes to increase public participation.

Potential increased opportunities for collaborative decision-making and consequent reduction in risk exposure amongst DKI Jakarta’s most vulnerable populations can help to address issues of social justice.

This paper synthesises information from a range of sources not available in English, and offers insights into a complex system of governance and modes for improving decision-making.

This article aims to show how communities with severe river flooding can develop sustainable flood plans that remediate environmental problems caused by previous river straightening and other structural flood controls.

The article builds on a case study of the nationally recognized Napa River Flood Protection Project (USA), which incorporates an ecological living river strategy and builds on strong community participation to restore a river and its floodplain. After discussing the drawbacks of structural flood control measures, and especially of river straightening, reviews the contents of the Napa Flood Project and the public participation process necessary for its design, approval and implementation.

The key lessons learned from Napa's flood project are that: undoing past structural works is difficult but feasible; ecological criteria can and should be used to design modern flood projects; involvement of a wide and diverse group of stakeholders is crucial to developing and implementing an environmentally sustainable flood management project; and the US Army Corps of Engineers can work with communities and depart from its typical, structural flood control approaches.

Information on straightened rivers is extremely limited. Furthermore, this study focuses on flood planning for US rivers, and may therefore be less useful elsewhere in the world where the frequency of river straightening may differ.

This case study provides a critique on river straightening, which is a poorly documented but fairly frequent approach to flood control. This article helps to fill gaps in the knowledge of how communities can, and are, addressing environmental concerns associated with flood controls and river straightening.

This chapter discusses some issues of diversity in hazard mitigation when just recovery is considered or not. Justice in hazard mitigation becomes crucial considering unequal distribution of resources, systemic racism, and social vulnerability to hazards. While there has been research on just recovery, there is little or no evidence of research that examines the issue of equity and justice in hazard mitigation, This chapter discusses what hazard mitigation is, the Disaster Mitigation Act of 2000 focusing on the planning process, public involvement in the planning process, some planning theories on vulnerability, and building the case for achieving and striving for justice and equity in promoting diversity in hazard mitigation. The chapter makes some recommendation on how to achieve diversity in hazard mitigation.
