Weaving Together a Decolonial Imaginary Through Design for Effective River Management: Pluriversal Ontological Design in Practice

Looking at how we, as designers, can move beyond charges of neo-colonialism in social design, this article uses the empirical example of a design project focused on the restoration of a riverine system in New Zealand to provide an outline of ways that pluriversal ontological design can occur in practice. Exploring how the use of design tools and frameworks (e.g., boundary objects and infrastructuring) can help build out a decolonial imaginary, the article demonstrates how— through our design practice— we are able to successfully acknowledge, and work with, different “ways of being” in the world.

Catastrophic floods in Kosi catchment during August 2008

A breach in embankment of Kosi barrage was reported on 18 August, 2008 which has changed its course and resulted in a fresh channel around 120 km to the east of its previous channel. At the time of failure of the embankment, gushing out of about 2832 m3/s water with great impact breaking into the Mahendra Rajmarg and then taking a southward route into the old 1892-1921 abandoned course of the river, thus leaving the pre-breach C-loop and following a straight route to the Ganga. In this study meteorological aspect are analysed in details in relation to the catastrophic flood in the Kosi river catchment during August 2008. It seems that this catastrophic flood may not be solely due to rainfall in the catchment of Kosi. The breach is due to incorrect strategies of river management, human negligence and poor maintenance of afflux bund of the barrage (Sinha, 2009).

Strategy for Sustainable Tami River Management as One of the Priority Watersheds in Indonesia

Rivers and their natural potential are important and useful to support the welfare of people's lives. The Tami River which is located in Keerom Regency is included in the management priority because it is a river located in the border area of Indonesia and Papua New Guinea. The Tami river ecosystem stores various kinds of biodiversity that are important to support human life. The research objective is to develop a strategy for managing the Tami river in a sustainable manner by considering it as a priority river within national borders. The results of the research on the Tami river have high biodiversity potential. More than 27 species from 21 plant families were found and 40 species from 28 tree families were also found around the river area. In addition to flora, there is also the potential for fauna of various types of mammals, Avivauna, Heterofauna and various types of birds around the Tami river. The potential of the Tami river can be developed to produce energy for power generation. The Tami river development strategy requires planned and synergized cooperation between parties so that it can be sustainable and provide benefits to the surrounding community.

A socio-hydrologic framework for understanding conflict and cooperation in transboundary rivers

Increasing hydrologic variability, accelerating population growth, and resurgence of water resources development projects have all indicated increasing tensions among the riparian countries of transboundary rivers. This article aims to review the existing knowledge on conflict and cooperation in transboundary rivers from a multidisciplinary perspective and propose a socio-hydrological framework that integrates the slow and less visible societal processes with existing hydrological-economic models, revealing the hidden feedbacks between changes in societal processes and hydrological changes. This framework contributes to understanding the mechanism that drives conflict and cooperation in transboundary river management.

River Re-naturalization - a Nature-based Solution for Climate Change in Urban Areas

The subject of the article is river management and their reconstruction in connection with the need to adapt urban areas to climate change. The article presents a fragment of a wider research. The aim of the study is to identify and indicate the main directions of activities undertaken in the field of river reconstruction, based on the analysis of documents and literature on the subject. The case study of the Wandle River - one of the tributaries of the Thames, running through heavily urbanized areas in London, is an example of the restoration of the river. In this case, the use of natural solutions improved: flood and drought risk management, stormwater retention, inhabitants' access to the river and biodiversity of natural habitats associated with the river.

Tradition lubuk larangan as a local wisdom for ecocultural tourism river management through landscape anthropolinguistic approach in Mandailingnese

Lubuk larangan is a pond that contains freshwater fishes in Kecamatan Tambangan, Kabupaten Mandailing Natal, North Sumatera. The objective of this study was to describe eco cultural tourism river management at the core of the landscape anthropolinguistic approach. The method was qualitative, and an interactive model was implemented. The data were collected by doing an interview and participant observation. Then they were analyzed data reduction, data display, and verifying/conclusion with landscape anthropolinguistic as an approach. This approach was the new paradigm to describe and explain the analysis from a linguistic perspective in landscape study. The study results showed that Lubuk larangan was a natural resource for the villagers economically and contained social, cultural ecology, and religious value. It became a tradition and belonged to Mandailingnese as their local wisdom. It can be concluded that Lubuk larangan became a concept for them to understand and apply management for maintaining environmental usage patterns with cultural-based tourism space.
