Almost half of countries globally are implementing national strategies to lower population salt intake towards the World Health Organization’s target of a 30% reduction by 2025(1). However, most are yet to lower population salt intake(1). We conducted process evaluations of national salt reduction strategies in Malaysia and Mongolia to understand the extent to which they were implemented and achieving their intended outcomes, using the findings to generate insights on how to strengthen strategies and accelerate population salt reduction. Mixed methods process evaluations were conducted at the mid-point of implementation of the strategies in Malaysia (2018-19) and Mongolia (2020-21)(2). Guided by theoretical frameworks, information on the implementation, mechanism and contextual barriers and enablers of the strategies were collected through desk-based reviews of documents related to salt reduction, interviews with key stakeholders (n = 12 Malaysia, n = 10 Mongolia), and focus group discussions with health professionals in Malaysia (n = 43) and health provider surveys in Mongolia (n = 12). Both countries generated high-quality evidence about salt intake and salt levels in foods, and culturally-specific education resources in 3 and 5 years respectively. However, in Malaysia there was moderate dose delivered and low reach in terms of education and reformulation activities. Within 5 years, Mongolia implemented education among schools, health professionals and food producers on salt reduction with high reach but with moderate dose and reach among the general population. There were challenges in both countries with respect to implementing legislative interventions and both could improve the scaling up of their reformulation and education activities to have population-wide reach and impact. In the first half of Malaysia’s and Mongolia’s strategies, both countries generated necessary evidence and education materials, mobilised health professionals to deliver salt reduction education and achieved small-scale salt reformulation in foods. However, both faced challenges in implementing regulatory policies and the scaling up of their reformulation and education activities to have population-wide reach and impact could be strengthened. Similar process evaluations of existing salt reduction strategies are needed to strengthen intervention delivery and inform areas for adaptation, to aid achievement of the WHO’s global target of a 30% reduction in population salt intake by 2025.

The Mongolian gazelle Procapra gutturosa is a wild ungulate ubiquitous across the largest remaining temperate grasslands of Mongolia, Russia and China. The species is nomadic and ranges over long distances, resulting in widely fluctuating abundance in any given location. Therefore, a comprehensive and range-wide survey is required to accurately estimate its global population size, but challenges are posed by the expansive geographical distribution and the political boundaries across the species’ vast range. To obtain an estimate of the total population, we compiled data from recent range-wide surveys. During 2019–2020, we estimated the population size in Mongolia by conducting line transect distance surveys and total counts, and by deriving numerical predictions for unsurveyed areas through data analysis. The gazelle's population in Russia was surveyed in 2020 across its summer range using simultaneous counts, transect surveys and expert knowledge. The distance sampling surveys in Mongolia revealed that slightly more than half of the gazelles along the transects were detected. Our assessment of the gazelle population, although probably an underestimate, suggests there are c. 2.14 million individuals in Mongolia and c. 30,000 in Russia. These results confirm that the Mongolian gazelle is the most abundant nomadic ungulate in the open plains across its range. However, to obtain more accurate estimates across all range states and effectively monitor the gazelle's population status, it is essential to implement standardized survey protocols that correct for imperfect detection. At present, the management of the Mongolian gazelle is inadequate, as there is a lack of regular monitoring to identify any adverse population changes that could necessitate conservation interventions.

The authors present results from a new research project focusing on the prehistory of the area surrounding a vast flint outcrop in Mongolia, called Tsakhiurtyn Hundi, in the borderland between the Gobi-Altai Mountains and Gobi Desert. They present the discovery of a cave and the results of its exploration, confirming its use by Pleistocene hunter-gatherers.

Innovations in horse equipment during the early Middle Ages provided advantages to societies from the steppes, reshaping the social landscape of Eurasia. Comparatively little is known about the precise origin of these crucial advances, although the available evidence points to early adoption in East Asia. The authors present new archaeological discoveries from western and northern Mongolia, dating to the fourth and fifth centuries AD, including a wooden frame saddle with horse hide components from Urd Ulaan Uneet and an iron stirrup from Khukh Nuur. Together, these finds suggest that Mongolian groups were early adopters of stirrups and saddles, facilitating the expansion of nomadic hegemony across Eurasia and shaping the conduct of medieval mounted warfare.

A Mongolian-German project is investigating abandoned early modern military and monastic sites in central Mongolia, including how the ruins of these urban nodes continue to shape cultural memory within nomadic society. Initial excavations have revealed a previously unknown site type, interpreted as garrisons from the period of Manchu rule (AD 1636–1911).

As wildlife becomes more isolated in human-dominated and rapidly changing environments, species conservation requires investment in landscape connectivity. Identifying stepping stones (discrete areas of suitable habitat that facilitate the movement of dispersing individuals) can help meet connectivity goals. We report the occurrence of the snow leopard Panthera uncia in Ikh Nart Nature Reserve, Mongolia, over 250 km from the nearest known population, one of the easternmost records for the species. Ikh Nart Nature Reserve lies within a region considered highly resistant to movement but harbours high densities of argali sheep Ovis ammon and Siberian ibexes Capra sibirica, both important prey items for snow leopards. This occurrence reveals a new distribution record for the species, the capacity of the species to move across low-quality environments, the value of investment in community conservation and collaborative park management, and the role of remote protected areas such as Ikh Nart Nature Reserve as stepping stones for facilitating population expansion and broader connectivity to other potentially suitable but unoccupied areas.

Beginning in the Middle Palaeolithic, human populations penetrated areas of Central Asia that are today characterised by extremely arid conditions. Mongolia's Gobi Desert comprises one such region. Tsagaan Agui Cave presents an example of the later Pleistocene occupation of this area, containing stratified evidence of diachronic, intense human and animal occupation.

The climatic, hydrographic, and environmental regimes of terminal Pleistocene and Holocene northwestern Mongolia are reconstructed using archaeological and pedological data sets at Bayan Nuur, a lake on the northwestern perimeter of the Altan Els dune field in eastern Uvs Province, Mongolia. The archaeological data consist of land-use patterns controlled for time via time-sensitive, diagnostic artifacts. The pedological data consist of soil classifications and radiocarbon dating of paleosols that track lake levels and water table. These data are combined using a geographic information system (GIS) to ascertain site and paleosol geographic relationships to modern lake levels at Bayan Nuur. They point to a more xeric Younger Dryas than previously recognized, significant Holocene lake regressions, and to Mid- to Late Holocene lake standstills/transgressions, the scale of which had previously been unrecognized. Combined, these data point to a complex late Quaternary picture of paleoclimate and paleoenvironment across the region and the importance of using multiple proxies, including archaeological data, in paleoecological reconstructions.

Cestodes of the genus Arostrilepis Mas-Coma and Tenora 1997 have a Holarctic distribution with 16 species occurring among 28 species of mostly arvicoline hosts. The type species of the genus is Arostrilepis horrida (von Linstow, 1901), described initially as Taenia horrida von Linstow, 1901, from murine rodents in Lower Saxony (Niedersachsen), Germany. Here we report the first helminth parasite from the mole-vole, Ellobius tancrei, in Mongolia which is the first subterranean rodent known to be infected with Arostrilepis in the Palearctic. In addition, we describe a new species: Arostrilepis batsaikhani n. sp. which most closely resembles A. microtis Gulyaev and Chechulin 1997, differing from this species with a genetic distance of about 4% (using cytochrome-b) and by having distinctly large cirrus spines, testes that are larger and fill the whole segment measured anterior–posterior and larger eggs.

This article describes the development of the moral economy of merit among the fishermen and rural poor of Dalai Village, Magtaal soum, Mongolia. In 1971, the historian E. P. Thompson used the term “moral economy” to describe a popular consensus on what was considered right and wrong in economic behavior, arguing that its provocation motivated the eighteenth-century English poor to engage in crowd-based political action. In contemporary, post-socialist eastern Mongolia, the rural poor have constructed a pervasive local discourse on what is considered legitimate (“merit-making” or buyantai) versus what is illegitimate in economic behavior that morally-condones their illegal wildlife procurement, selling, and smuggling activities. The political contexts of these case studies are compared in order to detail a similar political-economic progression: (1) the recent market liberalization of the commons, sparking moral outrage amongst those classes newly disadvantaged through this shift to the market; and (2) the formation of an anti-profiteering moral discourse among these classes, designed to limit the ability of others to economically capitalize off of these circumstances. Comparing the case studies, the moral economy is manifested as exchange practices involving commons-marked goods that distribute their benefits among the participants, envisioned as thereby promoting group wellbeing rather than the uneven accumulation by individuals.

In the thirteenth century AD, the city of Karakorum was founded as the capital of the Mongol Empire. Relatively little archaeological attention, however, has been directed at the site and the phenomenon of steppe urbanism. The authors report new magnetic and topographic surveys of the walled city and the surrounding landscape. The resulting maps reveal the city in unprecedented detail. Combining the magnetic and topographical data with aerial photographs, pedestrian surveys and documentary sources reveals the extent, layout and organisation of this extensive settlement. Road networks and areas of variable occupation density and types of activities deepen our understanding of this important commercial hub and royal palace, which is conceptualised as a form of ‘implanted’ urbanism.

Across Eurasia, horse transport transformed ancient societies. Although evidence for chariotry is well dated, the origins of horse riding are less clear. Techniques to distinguish chariotry from riding in archaeological samples rely on elements not typically recovered from many steppe contexts. Here, the authors examine horse remains of Mongolia's Deer Stone-Khirigsuur (DSK) Complex, comparing them with ancient and modern East Asian horses used for both types of transport. DSK horses demonstrate unique dentition damage that could result from steppe chariotry, but may also indicate riding with a shallow rein angle at a fast gait. A key role for chariots in Late Bronze Age Mongolia helps explain the trajectory of horse use in early East Asia.

The shift to sedentary lifeways represents a significant change in human adaptation. Despite the broadly contemporaneous timing of this transition across East Asia during the Holocene Climatic Optimum, such changes varied regionally. This article synthesises new and existing data from Neolithic sites on the Mongolian Plateau to reveal a simultaneous shift towards investment in site architecture, with distinct variation in the organisation of settlement and subsistence across biogeographic zones. The development of sedentary communities here emphasises the importance of climatic amelioration for incipient sedentism, and demonstrates how differences in ecological and cultural contexts can encourage various responses to the same environmental stimuli.
