“…Most of the South Asian DRR mechanisms are focused at reducing hazard risks, with less attention given to reducing vulnerabilities (Daly et al, 2017). For example, the Sri Lankan government's recent focus on managing urban wetlands in Colombo aims to prevent floods by preserving retention capacity of wetlands, with lack of attention to enhancing community resilience through livelihood enhancement (Subasinghe et al, 2022). The prevalence of Western scientific and engineering methods also can limit the proposed paradigm shift.…”

PurposeThe paper reviews existing literature on South Asian ecosystem-based disaster risk reduction (DRR) and identifies how community participation can be used to plan and implement ecosystem-based DRR approaches.Design/methodology/approachThe literature review methodology involved several stages. Firstly, the research objective was determined. Secondly keywords for the literature search were determined. Scopus, Google Scholar, JSTOR and AUT online library were utilized for the literature search. After the search, the literature was screened. The study design, methodology, results and limitations were identified and documented. After data extraction, the literature was analyzed. The patterns, trends and inconsistencies in the literature were identified based on the research question. Later the gaps, controversies and future research needs were identified. Then, a comprehensive and structured literature review that summarizes the relevant literature, synthesizes the findings and provides a critical evaluation of the literature was documented. After writing the document, it was reviewed and edited to ensure its clarity, accuracy and coherence.FindingsThe paper identifies four different themes recurrently emerging in literature on the importance of community participation in ecosystem-based DRR in South Asia. The themes are local community participation in ecosystem-based DRR governance, knowledge production, livelihood enhancement and increased public acceptance.Originality/valueThe paper also illustrates the challenges in integrating community participation with the dominant physical scientific approaches ecosystem-based DRR and proposes a five-element framework to facilitate the integration.

The most recent census report (2012) indicates that the Colombo district's total population is 2.3 million (DCS, 2012;Subasinghe et al, 2021). It occupies an approximate area of 700 km 2 in flat terrain situated in coastal plains topographically.…”

Monitoring the Impacts of Urbanisation on Environmental Sustainability Using Geospatial Techniques: A Case Study in Colombo District, Sri Lanka

et al. 2021

View full text Add to dashboard Cite

In recent years, a critical understanding of the sustainable urban environment has become central to many urban studies, leading numerous scholars to employ geospatial tools and techniques to examine the sustainability of growing cities in the developing world. In this study, the Colombo district where the capital city of Sri Lanka is located, was selected with the prospect of monitoring the impacts of urbanization on environmental sustainability. The study uses the spectral indices of remote sensing, including the Normalized Difference Vegetation Index (NDVI) and Normalized Difference Built-Up Index (NDBI), Land Surface Temperature (LST), and Environmental Criticality Index (ECI) to detect the aspects of urbanization and environmental sustainability of the study area. The results show that there has been a dramatic increase in environment criticality from 1997 to 2008, and a slight decrease indicated from 2008 to 2017, coinciding with the government urban planning initiatives. However, the decline of environmental sustainability of the city center and along the transport corridors could be identified in the context of this study. Finally, by drawing attention of the landscape and land use planners, the study emphasizes the aspects that should be considered in future urban planning.
