This document presents the methodology and findings for a national plastic waste inventory for Sri Lanka. It has been prepared as part of the project titled “Marine litter and micro-plastics: Promoting the environmentally sound management of plastic wastes and achieving the prevention and minimization of the generation of plastic wastes,”...

Although masting in Southeast Asia is characterized by the interspecific synchronization of reproduction, little is known about the variation in regeneration strategies among sympatric tree species during major masting events. Herein, we examined the hypothesis that non-abundant species achieve greater seed survival per seed production at the pre-...

Integrating the Sustainable Development Goals (SDGs) into climate actions is essential for a healthy planet and people. Yet, national climate policies and international climate support programs often fail to explicitly recognize the interconnections between climate concerns and other priorities covered under the SDGs. This failure can leave key...

The report assesses the level of public awareness of microplastic pollution and related hazards as well as the current status of microplastic monitoring facilities available in Sri Lanka’s state and private sector institutes, with an emphasis on the public water supply chain and identifying microplastic point sources upstream to ensure safe...

The global demand for plastic is expected to double in the next 20 years. The increasing demand for Single-Use Plastic Products (SUPPs) has become one of the main environmental problems in many developing countries, including Sri Lanka, through direct and indirect means, in the way of excessive consumption and the pollution of the environment...

River meandering and anabranching have become major problems in many large rivers that carry significant amounts of sediment worldwide. The morphodynamics of these rivers are complex due to the temporal variation of flows. However, the availability of remote sensing data and geographic information systems (GISs) provides the opportunity to analyze...

This summary report presents the results of the technical analysis of the third biennial update report of Malaysia, conducted by a team of technical experts in accordance with the modalities and procedures contained in the annex to decision 20/CP.19.

This report presents the challenges faced and opportunities revealed through a study of two cases of source-segregated waste collection by local authorities in Sri Lanka; Moratuwa Municipal Council, in Colombo, and Kataragama Pradeshiya Sabha, in Monaragala for the purpose of raising planning and decision making capacities not only in Sri Lanka but...

This case study report examines the establishment and evolution of plastic waste recycling under two different operational modalities in urban areas of Sri Lanka; 1) single municipal operation, and 2) PPP (Public Private Partnership) based operation. This report provides an analysis of each modality in terms of effectiveness, technical feasibility...

This report presents three case studies in the context of centralised large-scale composting facilities in Sri Lanka in order to reveal the factors and approaches that led to positive results under different type of operational modality, i.e., 1) single municipal operation, 2) provincial operation, and 3) joint consortium operation (operated by two...
