Multiple impacts (effects) on Inle lake ecosystems (Myanmar) examined by recording their strength and interaction in the lake catchment area. Numerous impacts affect Valued Ecosystem Components (VECs) over space and time thus resulting in cumulative impacts in environmental management. Cumulative nature of the impacts is a major issue. The present study proposes a conceptual framework for advancing Cumulative Effects Assessment (CEA). The study used a participatory appraisal technique for quantifying impacts and impact interactions. A combination of assessment tools at spatiotemporal scale...

The concept of cumulative effect assessment (CEA) as a theory and tool for the quantitative assessment of cumulative effects (impacts) on multifunctional wetlands was furthered in view of a an inherent and chronic lack of environmental data sets in the vast majority of ecosystems in the developing Asia that is a major stumbling block on the way of CEA. Whereas expert opinion as a CEA method has been long recognized, a participatory rural appraisal (PRA) as another important method was largely overlooked despite its strong validity under the circumstances when the required environmental data...
