Diversity and protection of Korean pine broad-leaved forests in the Manchurian Natural Area

Methods for the ecological-geographical analysis of the Manchurian Natural Area are discussed to perform estimation of the contemporary state, monitoring, and conservation of the biodiversity of Korean pine broad-leaved forests. The models used for conservation of the mountain Korean pine broad-leaved forests in the transboundary areas of Russia, China, the Democratic People’s Republic of Korea (DPRK), and the Republic of Korea should be based on the coordinated management of national resources. Estimating the ecological potential of Korean pine broad-leaved forests and the state and role played by forest ecosystems in the contemporary structure of the vegetation cover of the Manchurian Natural Area is significant for a more successful management of forests and scientifically grounded distribution of the nature reserves to conserve biodiversity. The united ecological-geographical system taking into account the regional peculiarities of forests can serve as a key in the development of the conservation of the biome.     

Appetites and aspirations: Consuming wildlife in Laos

Research on wildlife use is strongly associated with conservation and environmental debates. Yet, popular beliefs about wildlife consumption also offer many opportunities for discussing identity and social change. To demonstrate this, I examine ideas about eating common types of wildlife in Laos in light of the dialectical contrast between civilised settlements (muang) and the wild forest (pa). The exclusion of wildlife from the widely practised baci ritual and the popularity of wildlife consumption indicate the potency of these animals as social objects. In a contemporary context of widespread social and environmental change across Laos, the practice of eating wildlife is being constructed as an assertion of Lao identity that blends an idealised tradition with a status‐conscious modernity. Ambivalent desires for social transformation draw upon ambiguous symbols to find expression in beliefs as well as in popular social practice.     

The Future of Lao Cinema: The New Wave

The debut work of Mattie Do and Anysay Keola attests to the manner in which Lao cinema is being shaped by a new wave of young filmmakers determined to build a viable movie industry in the Lao PDR. With Chantaly, the first Lao horror movie, Mattie Do conjures up a world that cannot be fully explained rationally. She relies on the phi figure, and the belief of Lao people in supernatural beings, to raise serious questions about the traditional position occupied by women in the Lao family. Another film, Anysay Keola’s At the Horizon, the first Lao thriller, provides an edgy vision of contemporary Laos. The divide between the poor and the rich, tradition and modernity, is conveyed most originally via the soundtrack. Mattie Do and Anysay Keola are part of a new wave of promising young Lao directors who are fashioning a modern film industry in Laos.     

Environmental NGOs,dispossession, and the state: The ideology and praxis of African nature and development

Zimbabwe provides a significant context to examine the interplay of the new development rhetoric, the actions of powerful conservation organizations, donor policies, a relatively strong and stable government, and the empowerment of local communities. This interplay exists in diverse rural areas where the Communal Areas Management Program for Indigenous Resources (CAMPFIRE) is in various stages of experimentation and implementation. CAMPFIRE has been described as a philosophy of sustainable rural development that enables rural communities to manage, and benefit directly form indigenous wildlife. It is the best known of African efforts to permit African communities to re- assert their management of selected natural resources. The program has the official support of the Zimbabwean government. Nonetheless, there are many potential areas of serious conflict. Three case studies are utilized to explore how the challenges of repossession of critical environmental resources by marginalized communities in the changing context of state and NGO relationships where international tourism is a revenue generator for both the private sector and government.     

Randomized soil survey of the distribution of Burkholderia pseudomallei in rice fields in Laos

Melioidosis is a major cause of morbidity and mortality in Southeast Asia, where the causative organism (Burkholderia pseudomallei) is present in the soil. In the Lao People's Democratic Republic (Laos), B. pseudomallei is a significant cause of sepsis around the capital, Vientiane, and has been isolated in soil near the city, adjacent to the Mekong River. We explored whether B. pseudomallei occurs in Lao soil distant from the Mekong River, drawing three axes across northwest, northeast, and southern Laos to create nine sampling areas in six provinces. Within each sampling area, a random rice field site containing a grid of 100 sampling points each 5 m apart was selected. Soil was obtained from a depth of 30 cm and cultured for B. pseudomallei. Four of nine sites (44%) were positive for B. pseudomallei, including all three sites in Saravane Province, southern Laos. The highest isolation frequency was in east Saravane, where 94% of soil samples were B. pseudomallei positive with a geometric mean concentration of 464 CFU/g soil (95% confidence interval, 372 to 579 CFU/g soil; range, 25 to 10,850 CFU/g soil). At one site in northwest Laos (Luangnamtha), only one sample (1%) was positive for B. pseudomallei, at a concentration of 80 CFU/g soil. Therefore, B. pseudomallei occurs in Lao soils beyond the immediate vicinity of the Mekong River, alerting physicians to the likelihood of melioidosis in these areas. Further studies are needed to investigate potential climatic, soil, and biological determinants of this heterogeneity.     

Poverty and institutional management stand-off: a restoration and conservation dilemma for mangrove forests of Tanzania

Mangrove forests of Tanzania are reserved by law, but the capacity to effectively enforce this institution has remained far from reach and mangrove forests continue to be exploited as cheap sources of wood and forest land for other uses. Often, the rural poor who depend on mangroves for their subsistence are pointed out by the state institutions as culprits of the degradation. Promisingly though, this paradigm is being offset by the emerging positive view about human proclivity for caring and nurturing common resources. Traditional and community based forest management practices are emerging as appropriate alternatives to state control and institutional arrangement for ensuring sustainable management of forest resources. Nonetheless, community based management has not yet been robustly implemented for mangrove forests in Tanzania. Retrospectively, this paper argues that nationalization of mangrove forests has not been successful in reversing mangrove degradation. The experiences have instead been the frictions between people and the state, as desperate rural poor continue to plunder on and make a living at the expense of mangrove forests. The paper exemplify how policy failure, weak or dysfunctional state institutions in Tanzania compounded by little participatory awareness and self commitment are ruining the restoration and conservation initiatives.     

Integrating ecological and cultural values toward conservation and utilization of shrine/temple forests as urban green space in Japanese cities

In Japan, forests associated with shrines and temples are recognized as important components of urban green space, which can potentially function as centers for ecosystem conservation in rapidly urbanizing Japanese cities. In addition to their ecological value, shrine/temple forests have social value, providing recreational and aesthetic needs to residents of urban areas. We review the historical development of shrine/temple forests in Japan and discuss current conservation issues from both ecological and sociological perspectives. Generally, shrine forests are minimally managed and public access is discouraged, whereas temple forests are intensively managed for public display. Shrines tend to be spatially scattered across the landscape but associated with specific geographical features, whereas temples tend to be clustered. Their wide and random distribution in urban areas suggests that shrine forests can potentially be used as stepping stones in the urban green space network, whereas spatially clustered temple forests can be integrated to form large areas of green space. Species diversity of shrine/temple forests declines with decreasing area. The distribution pattern of species is not completely nested, indicating that although conservation of large forest fragments may be effective for maintaining landscape-level biodiversity, smaller forest fragments and adjacent precincts are sometimes significant because rare species occasionally inhabit them. Active management and ecological restoration, such as removal of invasive species, are also important to maintain the desirable near-natural forest conditions. A working group including the owner, community, regional government, and ecologists should be involved in creating an effective, long-term management plan. Because social and cultural values are diverse, basic ecological studies of shrine/temple forests would contribute a scientific basis that fosters public confidence in the process.     

Forest protection in Central India: do differences in monitoring by state and local institutions result in diverse social and ecological impacts?

Protection of forests and wildlife outside protected areas (PAs) is necessary for the conservation of wildlife. Extension of conservation efforts outside the existing PA may result in restrictions on local forest resource use. Such situations arise due to differences in understanding of forest as a resource for communities and as a conservation space for endangered species. A clearer focus is needed on the functionality and socio-ecological outcomes of different forest management institutions to address such issues. We conducted a study in a forest landscape connecting Pench and Tadoba-Andhari Tiger Reserves (TRs) in Central India. The two main forest management institutions were the Forest Department (FD) and local communities managing forest resources. We conducted vegetation surveys and focus group discussions in 15 villages selected based on presence or absence of active protection and monitoring of forest resources by either FD or local people. We found that forests with monitoring had significantly higher tree density and vegetation species richness compared to forests without monitoring. Tree density was observed to be higher in sites monitored by villagers rather than those monitored by FD. Self-regulation and resource sharing in locally monitored forests were more acceptable to local communities. In forests monitored by the FD, local communities indicated a feeling of alienation from the forest that weakened their motivation to protect the forest and wildlife. Recognition of local community rights is essential to achieve conservation goals and reduce social conflicts outside PAs, requiring collaboration between state and local institutions.     

Lao peasants on the move: Pathways of agrarian change in Laos

Grant Evans’ body of work on Laos consistently sought to understand how peasant society responded to political, social and economic change. As the Lao peasantry became ever more integrated both nationally and within the wider Southeast Asian region, and relations of market exchange came to dominate rural life, Evans maintained the need to reflect on Laos’ peasant roots to understand resulting pathways of agrarian change. This paper reconnects with this discussion in the contemporary Lao context, focusing on three dimensions of mobility: the widening spatial and sectoral ‘footprints’ of rural livelihoods; physical movement within and beyond rural settings in Laos; and reflections on issues of differentiation. We first track the political and policy changes that have most strongly influenced rural life since Evans’ early research on collectivisation, before exploring ways in which spatial integration, subsistence‐to‐commercial transition and migration have situated the remnants of Lao peasant society in a world of flows.     

An Epidemic of Dengue-1 in a Remote Village in Rural Laos

In the Lao PDR (Laos), urban dengue is an increasingly recognised public health problem. We describe a dengue-1 virus outbreak in a rural northwestern Lao forest village during the cool season of 2008. The isolated strain was genotypically “endemic” and not “sylvatic,” belonging to the genotype 1, Asia 3 clade. Phylogenetic analyses of 37 other dengue-1 sequences from diverse areas of Laos between 2007 and 2010 showed that the geographic distribution of some strains remained focal overtime while others were dispersed throughout the country. Evidence that dengue viruses have broad circulation in the region, crossing country borders, was also obtained. Whether the outbreak arose from dengue importation from an urban centre into a dengue-naïve community or crossed into the village from a forest cycle is unknown. More epidemiological and entomological investigations are required to understand dengue epidemiology and the importance of rural and forest dengue dynamics in Laos.     

Transitional forestry in New Zealand: re-evaluating the design and management of forest systems through the lens of forest purpose

Forestry management worldwide has become increasingly effective at obtaining high timber yields from productive forests. In New Zealand, a focus on improving an increasingly successful and largely Pinus radiata plantation forestry model over the last 150 years has resulted in some of the most productive timber forests in the temperate zone. In contrast to this success, the full range of forested landscapes across New Zealand, including native forests, are impacted by an array of pressures from introduced pests, diseases, and a changing climate, presenting a collective risk of losses in biological, social and economic value. As the national government policies incentivise reforestation and afforestation, the social acceptability of some forms of newly planted forests is also being challenged. Here, we review relevant literature in the area of integrated forest landscape management to optimise forests as nature-based solutions, presenting ‘transitional forestry’ as a model design and management paradigm appropriate to a range of forest types, where forest purpose is placed at the heart of decision making. We use New Zealand as a case study region, describing how this purpose-led transitional forestry model can benefit a cross section of forest types, from industrialised forest plantations to dedicated conservation forests and a range of multiple-purpose forests in between. Transitional forestry is an ongoing multi-decade process of change from current ‘business-as-usual’ forest management to future systems of forest management, embedded across a continuum of forest types. This holistic framework incorporates elements to enhance efficiencies of timber production, improve overall forest landscape resilience, and reduce some potential negative environmental impacts of commercial plantation forestry, while allowing the ecosystem functioning of commercial and non-commercial forests to be maximised, with increased public and biodiversity conservation value. Implementation of transitional forestry addresses tensions that arise between meeting climate mitigation targets and improving biodiversity criteria through afforestation, alongside increasing demand for forest biomass feedstocks to meet the demands of near-term bioenergy and bioeconomy goals. As ambitious government international targets are set for reforestation and afforestation using both native and exotic species, there is an increasing opportunity to make such transitions via integrated thinking that optimises forest values across a continuum of forest types, while embracing the diversity of ways in which such targets can be reached.     

Joint malaria surveys lead towards improved cross-border cooperation between Savannakhet province, Laos and Quang Tri province, Vietnam

ABSTRACT: BACKGROUND: In Savannakhet province, Laos and Quang Tri province, Vietnam, malaria is still an important health problem and most cases are found in the mountainous, forested border areas where ethnic minority groups live. The objectives of this study were to obtain a better joint understanding of the malaria situation along the border and, on the basis of that, improve malaria control methods through better cooperation between the two countries. METHODS: Fourteen villages in Savannakhet and 22 villages in Quang Tri were randomly selected within 5 km from the border where a blood survey for microscopic diagnosis (n = 1256 and n = 1803, respectively), household interviews (n = 400, both sides) and vector surveys were conducted between August and October 2010. Satellite images were used to examine the forest density around the study villages. RESULTS: Malaria prevalence was significantly higher in Laos (5.2%) than in Vietnam (1.8%) and many other differences were found over the short distance across the border. Bed net coverage was high (> 90%) in both Laos and Vietnam but, while in Laos more than 60% of the nets were long-lasting insecticide-treated, Vietnam used indoor residual spraying in this area and the nets were untreated. Anopheles mosquitoes were more abundant in Laos than in Vietnam, especially many Anopheles dirus were captured in indoor light traps while none were collected in Vietnam. The forest cover was higher around the Lao than the Vietnamese villages. After this study routine exchange of malaria surveillance data was institutionalized and for the first time indoor residual spraying was applied in some Lao villages. CONCLUSIONS: The abundance of indoor-collected An. dirus on the Laos side raises doubts about the effectiveness of a sole reliance on long-lasting insecticide-treated net in this area. Next to strengthening the early detection, correct diagnosis and prompt, adequate treatment of malaria infections, it is recommended to test focal indoor residual spraying and the promotion of insect repellent use in the early evening as additional vector interventions. Conducting joint malaria surveys by staff of two countries proved to be effective in stimulating better collaboration and improve cross-border malaria control.     

Molecular Epidemiology of Rabies Viruses Circulating in Two Rabies Endemic Provinces of Laos, 2011–2012: Regional Diversity in Southeast Asia

BackgroundAlthough rabies is endemic in Laos, genetic characterization of the viruses in this country is limited. There are growing concerns that development in the region may have increased transport of dog through Laos for regional dog meat consumption, and that this may cause spillover of the viruses from dogs brought here from other countries. This study was therefore undertaken to evaluate the current rabies situation and the genetic characteristics of rabies viruses currently circulating in Laos.MethodsWe determined the rate of rabies-positive samples by analyzing data from animal samples submitted to the Lao Ministry of Agriculture and Forestry’s National Animal Health Centre rabies laboratory from 2004 through 2011. Twenty-three rabies-positive samples were used for viral genetic characterization. Full genome sequencing was performed on two rabies viruses.ResultsRabies-positive samples increased substantially from 40.5% in 2004 to 60.2% in 2009 and continued at this level during the study period. More than 99% of the samples were from dogs, followed by cats and monkeys. Phylogenetic analyses showed that three rabies virus lineages belonging to the Southeast Asian cluster are currently circulating in Laos; these are closely related to viruses from Thailand, Cambodia and Vietnam. Lineages of the circulating Laos rabies viruses diverged from common ancestors as recently as 44.2 years and as much as 55.3 years ago, indicating periodic virus invasions.ConclusionThere is an increasing trend of rabies in Laotian animals. Similar to other rabies-endemic countries, dogs are the main viral reservoir. Three viral lineages closely related to viruses from neighboring countries are currently circulating in Laos. Data provide evidence of periodic historic exchanges of the viruses with neighboring countries, but no recent invasion.     

A Comprehensive Material Flow Account for Lao PDR to Inform Environmental and Sustainability Policy

Modern environmental and sustainability policy that acknowledges the linkages between socioeconomic processes and environmental pressures and impacts, and designs policies to decouple economic activity from environmental pressures and impacts, requires a sophisticated and comprehensive knowledge base. The concept of industrial metabolism provides a sound conceptual base, and material flow accounting—including primary material inputs and outflows of waste and emissions—provides a well‐accepted operationalization. Studies presenting a comprehensive material flow account for a national economy are rare, especially for developing countries. Countries such as Lao People's Democratic Republic (Lao PDR or Laos) face dual objectives of improving the material standard of living of their people while managing natural resources sustainably and mitigating adverse environmental impacts from growing resource throughput. Our research fills a knowledge gap, presents a comprehensive account of material inputs and outflows of waste and emissions for the Lao PDR national economy, and applies the accounting approach for a low‐income economy in Asia. We present a material balance for the years 2000 and 2015. For this research, we used data from Lao PDR national statistics and the accounting guidelines of the European Statistical Office (Eurostat), which pioneered the use of material flow data as part of its official statistical reporting. We demonstrate the feasibility of the accounting approach and discuss the robustness of results using uncertainty analysis conducted with statistical approaches commonly used in the field of industrial ecology, including Gauss's law of error propagation and Monte Carlo simulation. We find that the fast‐changing scale and composition of Lao PDR material flows, waste, and emissions presents challenges to the existing policy capacity and will require investment into governance of changed patterns of material use, waste disposal, and emissions. We consider the data analysis sufficiently robust to inform such a change in policy direction.     

Responsible resource management: the predicament and reform path for Chinese wetland conservation

Despite national conservation policies, international agreements and public support related to wetlands, a wide range of agricultural development and public works projects have resulted in the over-exploitation and degradation of wetlands during the past decades in China. The phenomenon of “the tragedy of the commons” in Chinese wetland conservation is recognized as an incentive problem provoked by a multi-stakeholder situation. This paper examines the governance of China’s wetlands and its hierarchical and functional–behavioral characteristics within the context of resource management. The results show that the administrative system in China wetland management depends on resource element-oriented legislation, in that various agencies managing different resources place various demands on wetland resources. This paper analyzes the responsibilities and incentives of various government administrators and other stakeholders as well as their behavioral logic and why such a multi-stakeholder mode fails to provide adequate wetland conservation. Using Heilongjiang Province as an example, it explains the conflicts between stakeholders within both the legislative system and those who administer wetland management. In addition, it suggests improvements, especially in the form of an integrated management system with an appropriate and unified system of administration.     

Forest conservation and environmental management in Nepal: a review

This paper provides information on the status of forests and environmental problems related to forestry in Nepal. It aims to integrate the conservation and sustainable management of forests as a part of environmental planning. A critical review of the main environmental problems with prioritization within the forestry sector; thorough review of all forest related documents, strategies, development plans, programs, institutional arrangements, policies mentioned in the Master Plan for Forestry Sector Nepal of 1988, and other relevant documents; identification of major gaps and constraints of forestry policy and plans and current practices of forest conservation and management have been done. The decline in forestry resources in Nepal took place in the past due to lack of appropriate policy to guide the legal, institutional and operational development for the forestry sector. Forestry policy in Nepal, in the past, was shaped by political and economic motives rather than ecological considerations. Policy formulation mechanisms exist in Nepal; however, there is an excessive delay in translating policies into legislation and then into operational rules and administrative orders. There is a need to implement the international obligations by transforming them into regulations in order to make them legally binding. The data to be generated in the coming years in the areas of forestry at both national and international levels suggest that we should revise the research priorities and strategies. Research to add value to the forest resource products has yet been neglected. More attention is required on regular monitoring and evaluation of the projects. A thorough evaluation of the programs and planning for the forestry sector in Nepal is urgently required to update the progress and revise the programs.     

Reconstructing the Human Genetic History of Mainland Southeast Asia: Insights from Genome-Wide Data from Thailand and Laos

Thailand and Laos, located in the center of Mainland Southeast Asia (MSEA), harbor diverse ethnolinguistic groups encompassing all five language families of MSEA: Tai-Kadai (TK), Austroasiatic (AA), Sino-Tibetan (ST), Hmong-Mien (HM), and Austronesian (AN). Previous genetic studies of Thai/Lao populations have focused almost exclusively on uniparental markers and there is a paucity of genome-wide studies. We therefore generated genome-wide SNP data for 33 ethnolinguistic groups, belonging to the five MSEA language families from Thailand and Laos, and analyzed these together with data from modern Asian populations and SEA ancient samples. Overall, we find genetic structure according to language family, albeit with heterogeneity in the AA-, HM-, and ST-speaking groups, and in the hill tribes, that reflects both population interactions and genetic drift. For the TK speaking groups, we find localized genetic structure that is driven by different levels of interaction with other groups in the same geographic region. Several Thai groups exhibit admixture from South Asia, which we date to ∼600–1000 years ago, corresponding to a time of intensive international trade networks that had a major cultural impact on Thailand. An AN group from Southern Thailand shows both South Asian admixture as well as overall affinities with AA-speaking groups in the region, suggesting an impact of cultural diffusion. Overall, we provide the first detailed insights into the genetic profiles of Thai/Lao ethnolinguistic groups, which should be helpful for reconstructing human genetic history in MSEA and selecting populations for participation in ongoing whole genome sequence and biomedical studies.     

Patterns of local wood use and cutting of Philippine Mangrove Forests

Small-scale wood harvesting from mangrove forests is a commonplace yet barely studied phenomenon. This paper integrates bio-ecological and ethnographic methods to examine local wood use and cutting of mangrove forests in two areas of the Philippines. Findings reveal considerable site variation in cutting intensity, with heavier cutting typically closer to settlements and in forest stands that are not effectively regulated by government or private interests. Overall, cutting is responsible for almost 90% of stem mortality in both natural and plantation forests. Field measurements confirm ethnographic evidence indicating that harvesting for construction wood, but not fuelwood, is both species- and size-selective. Mangrove management and conservation efforts can be made more effective by better understanding how local people are harvesting wood resources from these forests.     

Community Turnover of Wood-Inhabiting Fungi across Hierarchical Spatial Scales

For efficient use of conservation resources it is important to determine how species diversity changes across spatial scales. In many poorly known species groups little is known about at which spatial scales the conservation efforts should be focused. Here we examined how the community turnover of wood-inhabiting fungi is realised at three hierarchical levels, and how much of community variation is explained by variation in resource composition and spatial proximity. The hierarchical study design consisted of management type (fixed factor), forest site (random factor, nested within management type) and study plots (randomly placed plots within each study site). To examine how species richness varied across the three hierarchical scales, randomized species accumulation curves and additive partitioning of species richness were applied. To analyse variation in wood-inhabiting species and dead wood composition at each scale, linear and Permanova modelling approaches were used. Wood-inhabiting fungal communities were dominated by rare and infrequent species. The similarity of fungal communities was higher within sites and within management categories than among sites or between the two management categories, and it decreased with increasing distance among the sampling plots and with decreasing similarity of dead wood resources. However, only a small part of community variation could be explained by these factors. The species present in managed forests were in a large extent a subset of those species present in natural forests. Our results suggest that in particular the protection of rare species requires a large total area. As managed forests have only little additional value complementing the diversity of natural forests, the conservation of natural forests is the key to ecologically effective conservation. As the dissimilarity of fungal communities increases with distance, the conserved natural forest sites should be broadly distributed in space, yet the individual conserved areas should be large enough to ensure local persistence.
