Enhancing Soil and Water Conservation in Erosion‐Prone Ethiopia
Progress in soil erosion mitigation necessitates integrated approaches, wherein modeling is validated by field observations and enriched with local knowledge. This study adopts such an integrated methodology to discern areas of severe erosion, understand its relationship with land use and management, and capture local communities' perspectives on erosion causes, indicators, and mitigation measures. The study was done in the 211 km 2 Fota‐Gumara c…
Assessment of Soil Erosion Over Six Decades in a Long‐Term Experiment Using Fallout 137 Cs and Rusle
Soil erosion remains a major global concern affecting agricultural productivity and land sustainability. This study investigates the magnitude and variability of soil erosion in a long‐term experiment (LTE) established in 1963 in Colonia, Uruguay, aiming to compare the performance of the 137 Cs tracer technique and the RUSLE model across different crop rotations. We hypothesized that pasture inclusion into rotations reduces soil erosion compared …
Making air pollution legible
Air pollution is one of the most significant environmental threats to human health, causing over seven million premature deaths annually, with two‐thirds occurring in the Asia‐Pacific region. Each year, from February to April, northern Thailand experiences some of the world's worst air quality. The region's seasonal air pollution is primarily blamed on biomass burning from maize cultivation in the highlands and is perceived to have deteriorated o…
Conversion of native grasslands into croplands in the Pampa biome and its effects on source contributions to suspended sediment of the Ibirapuitã River, Brazil
Grain crops have expanded at the expense of native grasslands in South America's Pampa biome in recent decades, thereby, increasing the sediment delivery to the river systems. This study aimed to evaluate the impact of land use change on sediment source contributions in the Ibirapuitã catchment (5942 km 2 ), Southern Brazil. For this purpose, a sediment fingerprinting approach was developed based on organic matter composition, ultraviolet–visible…
Soil pollution in the European Union – An outlook
Soil pollution in the European Union (EU) is poorly quantified, because of several years of reduced attention and limited funding on soil research and monitoring. Moreover, issues such as different monitoring methodologies within Member States (MS), and quantification methods focused on pseudototal rather than the available fraction of pollutants, has been limiting our understanding of risk under soil pollution. Despite that, thanks to efforts fr…
Particulate Matters
Air pollution now affects 92 percent of the global population and is responsible for one out of nine deaths, nearly two thirds of which occur in Southeast Asia and the Western Pacific. Emerging work on the political ecology of air pollution examines how its noxious effects are unevenly distributed across social categories such as race and class. Geographers know much less about the social mechanisms through which air pollution and its risks and m…
Why did so few refugees return to the Fukushima fallout-impacted region after remediation? An interdisciplinary case study from Iitate village, Japan
Becoming a Crisis
Chiang Mai, Thailand, has long experienced seasonal air pollution episodes at the end of the dry season (February–April). While the severity and length of the episodes vary annually, popular narratives describe how the “haze crisis” is worsening. In this article, we address the role of the media in driving the growing awareness of seasonal air pollution in Chiang Mai. The article contributes to scholarship on the politics of the representation of…
Inexorable land degradation due to agriculture expansion in South American Pampa
Coastal heritage
This article presents the preliminary results of community-based archaeological and ethnographic research on the maritime heritage landscape along the Lanta Bay involving the Urak Lawoi sea nomads and with a focus on caves and rock art. It documents several newly-discovered rock art sites as well as the relationships local groups entertain, or not, with these caves. By doing so, it wishes to investigate the various social groups direct or indirec…
What were the main sources of sediment and associated radiocesium transported during the heavy 2019 typhoons in rivers draining the main Fukushima radioactive plume, Japan
lt;p>The Fukushima nuclear accident released large quantities of radionuclides into the environment in March 2011 and generated a 3000-km2 plume of soils heavily contaminated with Cs-137. Soil erosion in the region mainly takes place during typhoons generally occurring between July and October (Laceby et al., 2016). During these events, rivers draining the main plume may transport large quantities of sediment and radiocesium. Typhoon Hagibis that…

Structures sociales et structures génétiques dans les populations humaines
Dans cette note, nous revenons sur les grandes lignes de la conférence donnée lors des journées de la SAP 2019 concernant le champ actuel de l'ethnogénétique, qui s'intéresse entre autres à l'influence des systèmes de parenté sur la diversité génétique des populations humaines. Nous présentons certains des résultats principaux d'une étude ethnogénétique menée en Asie du Sud-Est dans douze populations présentant des systèmes de parenté variés, à f…
From Tai‐isation to Lao‐isation
This article uses ethnographic data collected since 1994 in Northern Laos to reassess the modalities of Tai cultural and political influence on the Khmu, a Mon‐Khmer‐speaking highland population, and to understand why, after so many years of ‘Tai‐isation’, distinct identities still exist. For Grant Evans, who conducted fieldwork in Tai‐Dam and Sing Moon (Ksing Mul) villages at the end of the 1980s, the answer lay in the fundamentally dualistic ch…

La pollution de l’air en Thaïlande du Nord
Durant la saison sèche, entre février et avril, un épais nuage de pollution recouvre une grande partie de l’Asie du Sud et du Sud-Est, provoquant de nombreux problèmes sanitaires (maladies respiratoires) et économiques (baisse de la fréquentation touristique, perturbation du trafic aérien). Contrairement aux aspects physico-chimiques et biophysiques (absence de précipitations en saison sèche, inversion des températures, combustion de biomasse not…
Residence rule flexibility and descent groups dynamics shape uniparental genetic diversities in South East Asia
OBJECTIVES: Social organization plays a major role in shaping human population genetic diversity. In particular, matrilocal populations tend to exhibit less mitochondrial diversity than patrilocal populations, and the other way around for Y chromosome diversity. However, several studies have not replicated such findings. The objective of this study is to understand the reasons for such inconsistencies and further evaluate the influence of social …

Of myths and metallurgy
Our recent discovery and excavation of a series of iron smelting furnaces, dated to the eighth and ninth century CE, near upland Rmet villages in northwest Laos, potentially sheds new light on the role of regional upland groups during the immediate pre-Tai period. The oral tradition associated with these furnaces emphasises the role of an ancient population of metallurgists who left the area under pressure from the Rmet. These stories could refer…

Les ruines, les « sauvages » et la princesse. Patrimoine et oralité à Viang Phu Kha, Laos
La petite ville de Viang Phu Kha, dans le Nord du Laos, est entourée de ruines et de vestiges matériels dont l’origine demeure obscure. Ces vestiges ont donné naissance à une abondante littérature orale partagée, avec quelques variations, par les populations locales, principalement tai (Yuan, Lue, Yang) et mon-khmer (Khmu, Rmet, Samtao). Cet article présente les premiers résultats d’un travail d’ethnohistoire commencé en 2009 dans cette région. I…
Planned Resettlement, Unexpected Migrations and Cultural Trauma in Laos
Though not officially considered a 'policy' by the Lao government, resettlement of ethnic minorities has become a central feature of the rural development strategy in Laos. Over the past ten years, a majority of highland villages have been resettled downhill, and the local administrations are planning to move the remaining villages in the coming years. This article draws on a national survey about resettlement in Laos, commissioned by UNESCO and …
Monks, Monarchs and Mountain Folks
The development of domestic (or national) tourism in Thailand in the second half of the 20th century relied on a new kind of relationship between the state and local cultures. Rural spaces have been reinvented and transformed into appealing visual and conceptual archetypes which sustain discourses on both local and national identity and history. Thai tourism allows a kind of pacification of the relations between the centre and the periphery, but …

Fils et maîtres du lac. Relations interethniques dans l’État Shan de Birmanie, François Robinne
Les pays d’Asie du Sud-Est péninsulaire, à l’exception de la Thaïlande, se caractérisent depuis les années 1970 par une relative opacité – et il s’agit dans bien des cas d’un doux euphémisme – pour la pratique de l’ethnologie de terrain. Que ce soit pour la Chine, le Vietnam, et surtout la Birmanie et le Laos, on ne dispose que de très peu d’études récentes sur les dynamiques sociales. Ne serait-ce qu’à ce titre, l’ouvrage de François Robinne est…
Solidarités intra-ethniques et relations interethniques. Sens et actualité des "sous-groupes" khmou (tmoï) au Nord Laos
L'article prend pour objet les subdivisions culturelles et territoriales que l'on observe chez les Khmou du Laos et que les membres de ce groupe nomment tmoï. Parmi les spécialistes de la culture khmou, certains voient dans les tmoï les vestiges d'une organisation territoriale antérieure à la fondation du royaume du Lan Xang par les Lao, tandis que d'autres affirment qu'il s'agit seulement de "surnoms" ne correspondant pas nécessairement à des ré…

L'exotique et le domestique
Alors que le tourisme constitue un objet de recherche en sciences sociales depuis maintenant presque quatre décennies, l’étude du tourisme domestique (ou national) dans les pays du Sud reste balbutiante. Rien, ou si peu, n’est écrit à ce propos, sinon en concevant les touristes du Sud comme des copies conformes à leurs modèles occidentaux. Cet article utilise des exemples tirés principalement de la Thaïlande, pour tracer le contour de cet « Autre…
Interethnic systems and localized identities
This chapter focuses on the history of interethnic relationships and social change amongst Khmu villages of the Nam Tha valley, in northwest Laos. It uses three kinds of data: accounts of the area by colonial explorers or administrators, ethnographic studies, such as those of Karl Gustav Izikowitz on the Lamet, or of Damrong Tayanin on the Khmou, and author's personal field data collected since 1994. The chapter demonstrates that the differences …
