Green economic development in Lao PDR : a Sustainability Window analysis of Green Growth Productivity and the Efficiency Gap

A novel 'Sustainability Window' (SuWi) approach is applied for simultaneous analysis of the pillars of sustainable development; social, environmental and economic, of Lao PDR. This new method employs a variety of indicators for a comprehensive and holistic analysis of sustainable development and green inclusive economy. The analysis is grounded in the assumption that economic development is required for social development, but that simultaneously development needs to be guarded or limited to protect the environment that underpins it. As all three dimensions of sustainable development are interlinked, a comprehensive analysis requires an analytical approach that is simultaneous. The analyses provide information on minimum levels of economic development that are needed to fulfil social sustainability criteria, in tandem with the maximum economic development that avoids breaching environmental sustainability criteria. If actual economic growth lies between these minima and maxima, we can interpret that development is more sustainable with respect to the relationships embodied by the selected social and environmental indicators. The main source of data is the database of the Sustainable Society Index (SSI) developed by the Sustainable Society Foundation (SSF). The indicators used by SSI have been chosen for the Sustainability Window analysis as they can be used to assess both 'weak' and 'strong' interpretations of sustainability. Weak sustainability is defined operationally as no increase in the environmental or carbon emissions intensity of the economy, while strong sustainability is defined as no increase in absolute emissions. Further, a novel Environmental Efficiency Gap analysis has been included in the Sustainability Window. This provides information about the necessary improvement in GDP production efficiency with respect to environmental emissions. Sustainability Window combined with Environmental Efficiency Gap analysis, provides critical knowledge for planners and decision makers. It provides strategic indications of how to aim for social and environmental sustainability through economic investment and growth targets. These new methods can be used in transdisciplinary research of sustainable development and can also assist in national and regional comparisons. In the case of Lao PDR, the analysis needs to be broadened for more fundamental understanding of the gaps and weaknesses. SuWi can be used to assess the sustainable development needed to address the Sustainable Development Goals by 2030. The SuWi does not provide direct policy recommendations as such, but helps to inform decision makers about the direction of development pathways towards these key goals. (C) 2018 The Authors.

Camera-trapping reveals new insights in the ecology of three sympatric muntjacs in an overhunted biodiversity hotspot

The Annamites ecoregion harbors exceptional levels of species richness and endemism, but intensive snaring has decimated populations of terrestrial mammals. Ungulates, such as muntjacs, are susceptible to snaring, and in need of effective conservation action. At least three muntjacs occur sympatrically in the region: the Annamite dark muntjac species complex Muntiacus rooseveltorum/truongsonensis, the northern red muntjac Muntiacus vaginalis, and the large-antlered muntjac Muntiacus vuquangensis. We conducted a landscape-scale systematic camera-trapping survey in Nakai-Nam Theun National Park to gather information on the ecology and distribution of these muntjacs. We analyzed camera-trap records within an occupancy framework to evaluate responses to environmental and anthropogenic variables, and to predict distributions across the protected area. We found varying responses to the covariates, indicating complex drivers of occurrence, though all three muntjac had higher occupancies in more inaccessible areas. Mean (95%) PAO in the protected area was higher for large-antlered muntjac (0.33 [0.22–0.49]), followed by Annamite dark muntjac (0.28 [0.18–0.39]), and then northern red muntjac (0.27 [0.15–0.42]). Large-antlered muntjac and northern red muntjac were widespread, while dark muntjac was restricted to a single high elevation area. Overall, our results provide new insights into muntjac ecology, distribution, and population status, and we discuss how this information can be used to inform conservation efforts. Given the high occupancies that we found for the Critically Endangered large-antlered muntjac, we argue that Nakai-Nam Theun National Park may be vital for the long-term survival of the species
