Short description of the intervention
The Krubong landfill site has been proposed to undergo a "thorough and safe environmental rehabilitation program[me]" so that the site can be developed as a public park (Ref. 1). Following completion of a feasibility study, it is envisaged that significant rehabilitation work to address environmental degradation and restoration of natural habitats will be required, after which the site will be developed into a public park (Ref. 1). The programme remains in its planning stage, but seeks to address Sustainable Development Goals (SGDs) 11.6 and 15.1 through protecting, restoring and promoting sustainable use of ecosystems and reversing land degradation and/or biodiversity loss; and reducing the environmental impact of cities by paying special attention to waste management and providing access to safe, open public spaces (Ref. 1). At a more local level, the programme intends to complement additional programmes laid out in Melaka's Resilience strategy document, including promoting both cycling and pedestrian networks and reshaping public spaces in the city (Ref. 1).

Goals of the intervention
As summarised by Ref. 1, the following goals have been identified for the intervention:
- restoration of natural ecosystems, landscapes and biodiversity;
- enhancement of attractiveness of Melaka to residents and visitors;
- potential provision of access to green spaces in urban areas for residents, encouraging active and healthy lifestyles;
- provision of both flood and air pollution mitigation, in addition to reducting urban heat island effects.
Quantitative targets
Still in the envisioning stage of the intervention, quantitative do not yet appear to have been determined for the project. The intervention is to be aligned with SDG Goals 11.6 and 15.1, so ought to pursue the protection, restoration and promotion of sustainable use of ecosystems and the reversing of land degradation and/or biodiversity loss; and also pursue the reduction of the environmental impact of the city, by a) paying special attention to waste management and b) providing access to safe, open public spaces (Ref. 1).

The Department of Management Services and Department of Environmental Health is to conduct a feasibility study to understand the current extent of environmental degradation at the site in order to determine a suitable programme of rehabilitation which will "render the site suitable for public use" (Ref. 1).
Monitoring indicators defined
As above, due to the intervention remaining in its envisioning stage at present, monitoring indicators are yet to be defined.

Implementation activities
Following the completion of a feasibility study, the site will undergo significant rehabilitation in order to counteract the environmental degradation which has occurred to date and restore natural habitats (Ref. 1). In particular, attention will be paid to reducing potential water pollution which may occur due to the site's close proximity to the Melaka River and the potential for leachate to be released from the site (Ref. 1). Having had the site rehabilitated and the natural habitat restored, the site will then be developed into a public park (Ref. 1).

The Transform Krubong Landfill into Public Park initiative has been developed as a sub-project of the Resilient Melaka Strategy. The Resilience Strategy is split into three phases: Preliminary Resilience Assessment (Phase I), Developing the Resilience Strategy (Phase II) and Implementation of the Resilience Strategy (Phase III). Whilst the Krubong landfill sub-project is yet to be implemented (Phase III) and the participatory methods which it might entail are yet to be detailed, the development of the Resilience Strategy itself drew upon information provided during stakeholder engagement sessions and workshops (Ref. 1). It was based on the identification of key resilience strategies identified within these workshops that specific actions were developed for implementation, one of which was the Krubong Landfill into Public Park project (Ref. 1).

NBS intervention implemented in response to a local regulation/strategy/plan
Yes
Please specify the "local regulation/strategy/plan"
The intervention is to be implemented in response to the development of the Resilient Melaka Strategy (Ref. 1). The Strategy itself has been developed in response to several existing city-wide planning documents, in recognition that whilst these existing documents promoted resilience, they often focused upon "urban development, economic development or resource efficiency rather than the holistic, multi-sector approach promoted by the concept of resilience" (Ref. 1).
Mandatory or voluntary intervention
Voluntary (spontaneous)
Please specify other type of voluntary intervention
The intervention has arisen as a result of the Melaka City Council's voluntary development of a Resilience Strategy (Ref. 1).

Yes
Please specify the general plan with GI/NBS section
Melaka has developed a Green City Action Plan (2017-2030) (Ref. 4). Whilst the plan does not specifically revolve around nature-based solutions nor green infrastructure, it does highlight how, amongst other initiatives, a green city approach ought to, with regards to the environment, "focus...on managing land, water and air in an efficient manner to maintain the long term sustainability of these natural resources...and reduc[e] vulnerabilities to natural hazards and climate change impacts by enhancing resilience and managing disaster risks" (Ref. 4). The Melaka State Climate Action Plan 2020 - 2030 which has since been developed also highlights how "ecosystem and biodiversity provide ‘services’ which influence climate change", and how green infrastructure strategies should be explored to promote adaptation and mitigation (Ref. 5).
If there is a relevant strategy or plan, please specify the theme / type of the plan.

Which of the involved actors was motivated by this model?
Please specify technological innovation
Through the remediation and rehabilitation of the Krubong landfill site, and its eventual conversion into an alternate land-use, suitable for public use as a park, technological innovation will be undergone (Ref. 1).
Please specify novelty level of the innovation
There is no information provided alongside the proposed intervention to suggest that the project idea and/or design have been derived from existing initiatives within the city. It appears rather that the intervention was developed during Phases I and II of the Resilient Melaka strategy, in which expert opinion was elicited on the most pressing issues which the city faces as regards its resilience (Ref. 1).
Please specify Replicability/Transferability
There is no information provided to suggest that the Krubong initiative will be transferred to additional landfill sites within the city. However, the introduction of policies that aim to reduce the amount of waste sent to landfills may see similar initiatives be invoked further down the line (see Ref. 5 for further detail on such policies).
Impacts, benefits
Please specify other economic impact
General economic impacts on the city, although this is not explicitly stated within the project documents (Ref. 1).
Description of environmental benefits
Prior to its conversion into a landfill site, Krubong was reported as a "swamp forest planted with close Nypa fruticans and Melaleuca leucadendra trees" (Ref. 3). The Krubong project aims to restore natural ecosystems, landscapes and biodiversity at the site (Ref. 1). Through this rehabilitation process, air quality is hoped to be improved, as is the water quality of the adjacent Melaka River which is at risk of leachate contamination (Ref. 1).

The project is considered to also have the potential to reduce the urban heat island effect and provide flood mitigation, likely through the increased presence of greenspace (Ref. 1).
Economic impacts
Description of economic benefits
The project intends to "enhance [the] attractiveness of Melaka to residents and visitors" (Ref. 1), which may have economic impacts on the city, although this is not explicitly stated within the project documents.
Description of social and cultural benefits
Through the rehabilitation and restoration of the site, the initiative has the potential to provide "residents with access to green spaces in urban areas", thereby "encouraging active and healthy lifestyles" (Ref. 1). By further linking in with additional initiatives which have been proposed during Phases I and II of the Resilience Strategy, conversion of the site may further enhance health benefits. In particular, health benefits may be achieved through connecting with the wider actions of 'reshaping public spaces in the city' more generally, and connecting 'cycling and pedestrian networks' in the city (Ref. 1).
